REFERENCE TO PRIOR APPLICATIONS [0001] This application claims priority to U.S. provisional application 60/929,739 filed Jul. 11, 2007, and to French patent application 0755935 filed Jun. 21, 2007, both incorporated herein by reference. FIELD OF THE INVENTION [0002] The present invention relates to compositions comprising two different polyester polymers and to their use, in particular in cosmetics such as lipsticks. Novel polyesters are also described. [0003] The compositions according to the invention preferably can be applied to substrates, such as the skin of the face or body, lips and keratinous substances, such as the hair, eyelashes, eyebrows and nails. [0004] Additional aspects and other features of the present invention will be set forth in part in the description that follows and in part will become apparent to those having ordinary skill in the art upon examination of the following or may be learned from the practice of the present invention. The advantages of the present invention may be realized and obtained as particularly pointed out in the appended claims. As will be realized, the present invention is capable of other and different embodiments, and its several details are capable of modifications in various obvious respects, all without departing from the present invention. The description is to be regarded as illustrative in nature, and not as restrictive. BACKGROUND OF THE INVENTION [0005] There exist numerous cosmetic compositions for which properties of gloss of the film deposited, after application to keratinous substances (skin, lips, superficial body growths), are desired. Mention may be made, for example, of lipsticks, nail varnishes or some hair products. [0006] In order to obtain such a result, it is possible to combine specific starting materials, in particular lanolins, with “glossy” oils, such as polybutenes, which, however, exhibit a high viscosity; or esters of fatty acid or alcohol having a high carbon number; or else certain vegetable oils; or also esters resulting from the partial or complete esterification of a hydroxylated aliphatic compound with an aromatic acid, as described in Patent Application EP 1 097 699. [0007] It is also known to combine lanolins with polyesters obtained by sequential reaction of castor oil with isostearic acid and then with succinic acid, as described in U.S. Pat. No. 6,342,527. [0008] In order to improve the gloss of the film deposited, and also its hold, the proposal has also been made to use esters resulting from the condensation of a polyol with a carboxylic acid of “neo” type, in particular in FR 2 838 049. [0009] Mention may also be made of EP 1 457 201, which describes a composition combining a polyester of triglycerides of hydroxylated carboxylic acids and an oil of low molecular weight chosen from polybutylenes, hydrogenated polyisobutylenes, hydrogenated or nonhydrogenated polydecenes, vinylpyrrolidone copolymers, linear fatty acid esters, hydroxylated esters, C 24 -C 28 branched fatty alcohol or fatty acid esters, silicone oils and/or oils of vegetable origin. A description is given, in Patent Application EP 0 792 637, of a composition combining an aromatic ester and a polymer of polybutene or polyisobutene type. [0010] A description is given, in Patent Application EP 1 155 687, of a process which consists in incorporating, in an oily phase composed of a cosmetically acceptable oil, an organopolysiloxane having at least 2 groups capable of establishing hydrogen bonds. [0011] However, these compositions and combinations, even if they significantly improve the gloss, are still considered inadequate from the viewpoint of the long-lasting hold of this gloss over time. DESCRIPTION OF THE PREFERRED EMBODIMENTS [0012] The polymers used in the context of the present invention are preferably alkyd resins, which constitute a specific class of polyesters, being the reaction product of polyols and polycarboxylic acids, generally modified by unsaturated fatty acids, such as oleic acid, or by unsaturated oils, for example soybean oil or castor oil. [0013] Cosmetic compositions comprising polyesters have been described in the prior art. Mention may in particular be made of the document FR 2 562 793, which describes the use of sucrose benzoate in combination with toluenesulphonamide/formaldehyde resins; or the document JP61246113, which describes the use of sucrose benzoate in combination with an alkyd resin modified with glycidyl versatate ester. Mention may also be made of WO2002243676, which describes the use of a neopentyl glycol trimellitate adipate polyester resin in combination with alkyl acrylate and methacrylate copolymers. JP58023614 is also known, which describes the use of a modified polyester obtained by condensation of pentaerythritol with cis-4-cyclohexene-1,2-dicarboxylic acid and castor oil fatty acids and then reaction with a dioxirane compound of epoxy resin type; or JP54011244 is also known, which describes the use of a modified polyester obtained by condensation of dipentaerythritol with cyclohexane-1,2-dicarboxylic acid and castor oil fatty acids and then reaction with a dioxirane compound of epoxy resin type. [0014] The polyesters used in the context of the present invention have a different structure from known polyesters. In addition, when they are formulated in combination with specific ingredients, they make it possible to obtain cosmetic properties which are the same as or indeed even better than the performances already obtained with known polyesters. [0015] One aim of the present invention is to provide cosmetic compositions, the gloss of which is improved in comparison with the compositions of the prior art comprising other polyesters, and the hold of the gloss of which is improved over time [0016] The inventor has discovered, surprisingly and unexpectedly, that two specific polyesters result in compositions, the hold of the gloss of which is improved. Compositions, preferably cosmetic compositions, comprising these polyesters make up a part of the invention. [0017] One subject-matter of the present invention is thus a composition, comprising: at least one polyester capable of being obtained by reaction: of at least one polyol comprising 3 to 6 hydroxyl groups; of at least one nonaromatic branched monocarboxylic acid; of at least one aromatic monocarboxylic acid, and of at least one polycarboxylic acid comprising at least 2 carboxyl groups COOH and/or one cyclic anhydride of such a polycarboxylic acid, at least one polyester capable of being obtained by reaction: of at least one polyol comprising 3 to 6 hydroxyl groups; of at least one nonaromatic linear monocarboxylic acid; of at least one aromatic monocarboxylic acid, and of at least one polycarboxylic acid comprising at least 2 carboxyl groups COOH and/or one cyclic anhydride of such a polycarboxylic acid. [0028] Naturally, the two polyesters are different from one another. [0029] The composition of the invention can be provided in any form including the form of a paste, solid or more or less viscous cream. It can be an oil-in-water or water-in-oil emulsion or a stiff or soft anhydrous gel. In particular, it is provided in the form cast as a stick or in a dish and more especially in the form of an anhydrous stiff gel, in particular of an anhydrous stick. [0030] According to another of its aspects, a subject-matter of the present invention is a composition, comprising: a first benzoic acid/isophthalic acid/isostearic acid/pentaerythritol polymer, and a second benzoic acid/isophthalic acid/stearic acid/pentaerythritol polymer. [0033] The ratio by weight of the first polymer to the second polymer is advantageously between 50/1 and 2/1, for example between 30/1 and 20/1. [0034] The term “hydrocarbon” is understood to mean a radical or a compound formed essentially, indeed even composed, of carbon and hydrogen atoms and optionally of oxygen, nitrogen, sulphur or phosphorus atoms but not comprising silicon or fluorine atoms. It can comprise alcohol, ether, carboxylic acid, amine and/or amide groups. Preferably, the adjective “hydrocarbon” denotes a radical or a compound composed solely of carbon and hydrogen, and oxygen, atoms. [0035] The term “branched” is understood to mean a compound comprising at least one branching. More generally, the number of branchings of a molecule corresponds to the number of side groups comprising at least one carbon atom and branched on the main chain of the molecule, the main chain corresponding to the longest carbon chain of the molecule (see Organic Chemistry, S. H. Pine, 5th Edition, McGraw-Hill, Chapter 3). Polyesters (or Polycondensates) [0036] Polyesters (also known subsequently as polycondensates) are advantageously obtained by reaction of a polyol, a polycarboxylic acid, a nonaromatic branched or linear monocarboxylic acid and an aromatic monocarboxylic acid. [0037] The first polymer can be obtained by reaction of a polyol, a polycarboxylic acid, a nonaromatic branched monocarboxylic acid and an aromatic monocarboxylic acid. [0038] The second polymer is advantageously obtained by reaction of a polyol, a polycarboxylic acid, a nonaromatic linear monocarboxylic acid and an aromatic monocarboxylic acid. [0039] According to one embodiment, the content of nonaromatic monocarboxylic acid is between 5 and 80% by weight, preferably between 20 and 70% by weight, for example from 25 to 65% by weight, with respect to the total weight of the polycondensate. [0040] According to another embodiment, the polyesters are advantageously obtained from the reaction of a polyol, a polycarboxylic acid and at least one nonaromatic monocarboxylic acid, the monocarboxylic acid being in a high content. [0041] The polycondensates are capable of being obtained by esterification/polycondensation, according to methods known to a person skilled in the art, of the constituents described below. [0042] One of the constituents useful in the preparation of the polycondensates according to the invention is a polyol, preferably comprising 3 to 6 hydroxyl groups, in particular 3 or 4 hydroxyl groups. Use may very clearly be made of a mixture of such polyols. [0043] The polyol can in particular be a saturated or unsaturated and linear, branched and/or cyclic carbon, in particular hydrocarbon, compound which comprises 3 to 18 carbon atoms, in particular 3 to 12 carbon atoms, indeed even 4 to 10 carbon atoms, and 3 to 6 hydroxyl (OH) groups and which can additionally comprise one or more oxygen atoms intercalated in the chain (ether functional group). [0044] The polyol is preferably a saturated, linear or branched, hydrocarbon compound comprising 3 to 18 carbon atoms, in particular 3 to 12 carbon atoms, indeed even 4 to 10 carbon atoms, and 3 to 6 hydroxyl (OH) groups. [0045] It can be chosen, alone or as a mixture, from: triols, such as 1,2,4-butanetriol, 1,2,6-hexanetriol, trimethylolethane, trimethylolpropane or glycerol; tetraols, such as pentaerythritol (tetramethylol-methane), erythritol, diglycerol or ditrimethylolpropane; pentols, such as xylitol, hexyls, such as sorbitol and mannitol; or also dipentaerythritol or triglycerol. [0050] Preferably, the polyol is chosen from glycerol, pentaerythritol, diglycerol, sorbitol and their mixtures; and better still the polyol is a tetraol, such as pentaerythritol. [0051] The polyol, or the polyol mixture, preferably represents 10 to 30% by weight, in particular 12 to 25% by weight and better still 14 to 22% by weight of the total weight of the final polycondensate. [0052] Another constituent for the preparation of the first polyester according to the invention is a nonaromatic branched monocarboxylic acid. The nonaromatic branched monocarboxylic acid can be saturated or unsaturated, comprising 6 to 32 carbon atoms, in particular 8 to 28 carbon atoms and better still 10 to 24, indeed even 12 to 20, carbon atoms. Use may very obviously be made of a mixture of such nonaromatic monocarboxylic acids. The term “nonaromatic branched monocarboxylic acid” is understood to mean a compound of formula RCOOH in which R is a saturated or unsaturated and branched hydrocarbon radical comprising 5 to 31 carbon atoms, in particular 7 to 27 carbon atoms and better still 9 to 23 carbon atoms, indeed even 11 to 19 carbon atoms. Preferably, the R radical is saturated. Better still, the R radical is a branched C 5 -C 31 , indeed even C 11 -C 21 , radical. [0053] In a specific embodiment of the invention, the non-aromatic branched monocarboxylic acid exhibits a melting point of greater than or equal to 25° C., in particular of greater than or equal to 28° C., indeed even 30° C.; this is because it has been found that, when such an acid is employed, in particular in a large amount, it is possible, on the one hand, to obtain good gloss and good hold of the gloss and, on the other hand, to reduce the amount of waxes normally present in the composition envisaged. [0054] Mention may be made, among nonaromatic branched monocarboxylic acids capable of being employed, of, alone or as a mixture: [0000] isoheptanoic acid, 4-ethylpentanoic acid, 2-ethylhexanoic acid, 4,5-dimethylhexanoic acid, 2-heptylheptanoic acid, 3,5,5-trimethylhexanoic acid, isooctanoic acid, isononanoic acid or isostearic acid. [0055] Preferably, use may be made of 2-ethylhexanoic acid, isooctanoic acid, isoheptanoic acid, isononanoic acid, isostearic acid and their mixtures and better still isostearic acid. [0056] The nonaromatic branched monocarboxylic acid or the mixture of the acids preferably represents 30 to 80% by weight, in particular 40 to 75% by weight, indeed even 45 to 70% by weight and better still 50 to 65% by weight of the total weight of the final polycondensate. [0057] Another constituent for the preparation of the second polyester according to the invention is a nonaromatic linear monocarboxylic acid. The nonaromatic monocarboxylic acid can be saturated or unsaturated, comprising 6 to 32 carbon atoms, in particular 8 to 28 carbon atoms and better still 10 to 24, indeed even 12 to 20, carbon atoms.

[0059] In a specific embodiment of the invention, the nonaromatic monocarboxylic acid exhibits a melting point of greater than or equal to 25° C., in particular of greater than or equal to 28° C., indeed even 30° C.; this is because it has been found that, when such an acid is employed, in particular in a large amount, it is possible, on the one hand, to obtain good gloss and the hold of the gloss and, on the other hand, to reduce the amount of waxes normally present in the composition envisaged.

[0212] The linear hydrocarbon waxes are advantageously chosen from substituted linear alkanes, unsubstituted linear alkanes, unsubstituted linear alkenes or substituted linear alkenes, an unsubstituted compound being composed solely of carbon and hydrogen. The substituents mentioned above not comprising carbon atoms. [0213] The linear hydrocarbon waxes include polymers and copolymers of ethylene with a molecular weight of between 400 and 800, for example the Polywax 500 or Polywax 400 sold by New Phase Technologies. [0214] The linear hydrocarbon waxes include linear paraffin waxes, such as the paraffin waxes S&P 206, S&P 173 and S&P 434 from Strahl & Pitsch. [0215] The linear hydrocarbon waxes include long-chain linear alcohols, such as the products comprising a mixture of polyethylene and of alcohols comprising 20 to 50 carbon atoms, in particular the Performacol 425 or Performacol 550 (mixture in proportions 20/80) sold by New Phase Technologies. [0216] Examples of silicone waxes are, for example: the C 20-24 alkyl methicone, C 24-28 alkyl dimethicone, C 20-24 alkyl dimethicone and C 24-28 alkyl dimethicone sold by Archimica Fine Chemicals under the reference SilCare 41M40, SilCare 41M50, SilCare 41M70 and SilCare 41M80, the stearyl dimethicones with the reference SilCare 41M65 sold by Archimica or with the reference DC-2503 sold by Dow Corning, the stearoxytrimethylsilanes sold under the reference SilCare 1M71 or DC-580, the products Abil Wax 9810, 9800 or 2440 from Wacker Chemie GmbH, the C 30-45 alkyl methicones sold by Dow Corning under the reference AMS-C30 Wax and the C 30-45 alkyl dimethicones sold under the reference SF1642 or SF1632 by General Electric. [0222] The amount of wax in the composition according to the invention can range from 5 to 70% by weight, with respect to the total weight of the composition, preferably from 5 to 40% by weight and better still from 10 to 30% by weight. Coloring Material [0223] The composition according to the invention can comprise a colouring material in a proportion of, e.g., 0.5 to 50% of colouring material, preferably of 2 to 40% and better still of 5 to 30%, with respect to the total weight of the composition. [0224] The colouring material can be any inorganic and/or organic compound exhibiting an absorption between 350 and 700 nm or capable of generating an optical effect, such as the reflection of incident light or interferences, for example. [0225] The colouring materials of use in the present invention are chosen from all the organic and/or inorganic pigments known in the art, in particular those which are described in the Kirk-Othmer Encyclopaedia of Chemical Technology and in Ullmann's Encyclopaedia of Industrial Chemistry. [0226] Mention may be made, as examples of inorganic colouring materials, of titanium dioxide, which is or is not surface treated, zinc oxide, zirconium or cerium oxides, iron or chromium oxides, manganese violet, ultramarine blue, chromium hydrate and ferric blue. For example, the following inorganic pigments can be used: Ta 2 O 5 , Ti 3 O 5 , Ti 2 O 3 , TiO, ZrO 2 as a mixture with TiO 2 , ZrO 2 , Nb 2 O 5 , CeO 2 or ZnS. [0227] Mention may be made, as examples of organic colouring materials, of nitroso, nitro, azo, xanthene, quinoline, anthraquinone, phthalocyanine, of metal complex type, isoindolinone, isoindoline, quinacridone, perinone, perylene, diketopyrrolopyrrole, thioindigo, dioxazine, triphenylmethane or quinophthalone compounds. [0228] In particular, the colouring materials can be chosen from carmine, carbon black, aniline black, azo yellow, quinacridone, phthalocyanine blue, sorghum red, the blue pigments classified in the Colour Index under the references CI 42090, 69800, 69825, 73000, 74100 and 74160, the yellow pigments classified in the Colour Index under the references CI 11680, 11710, 15985, 19140, 20040, 21100, 21108, 47000 and 47005, the green pigments classified in the Colour Index under the references CI 61565, 61570 and 74260, the orange pigments classified in the Colour Index under the references CI 11725, 15510, 45370 and 71105, the red pigments classified in the Colour Index under the references CI 12085, 12120, 12370, 12420, 12490, 14700, 15525, 15580, 15620, 15630, 15800, 15850, 15865, 15880, 17200, 26100, 45380, 45410, 58000, 73360, 73915 and 75470, and the pigments obtained by oxidative polymerization of indole or phenol derivatives, as described in Patent FR 2 679 771. [0229] The pigments in accordance with the invention can also be in the form of composite pigments, as described in Patent EP 1 184 426. These composite pigments can be composed in particular of particles comprising an inorganic core, at least one binder, which provides for the attachment of the organic pigments to the core, and at least one organic pigment at least partially covering the core. [0230] The colouring materials can be chosen from dyes, lakes or pigments. [0231] The dyes are, for example, fat-soluble dyes, although water-soluble dyes may be used. The fat-soluble dyes are, for example Sudan Red, D & C Red 17, D & C Green 6, β-carotene, soybean oil, Sudan Brown, D & C Yellow 11, D & C Violet 2, D & C Orange 5, quinoline yellow or annatto. They can represent from 0 to 20% of the weight of the composition and better still from 0.1 to 6%. The water-soluble dyes are in particular beetroot juice or methylene blue and can represent from 0.1 to 6% by weight of the composition (if present). [0232] The term “lake” is understood to mean dyes adsorbed on insoluble particles, the combination thus obtained remaining insoluble when used. The inorganic substrates on which the dyes are adsorbed are, for example, alumina, silica, calcium sodium borosilicate, calcium aluminium borosilicate and aluminium. Mention may be made, among organic dyes, of cochineal carmine. [0233] Mention may be made, as examples of lakes, of the products known under the following names: D & C Red 21 CI 45 380), D & C Orange 5 CI 45 370), D & C Red 27 CI 45 410), D & C Orange 10 CI 45 425), D & C Red 3 CI 45 430), D & C Red 7 (CI 15 850:1), D & C Red 4 (CI 15 510), D & C Red 33 (CI 17 200), D & C Yellow 5 (CI 19 140), D & C Yellow 6 (CI 15 985), D & C Green CI 61 570), D & C Yellow 10 CI 77 002), D & C Green 3 CI 42 053) or D & C Blue 1 CI 42 090). [0234] The term “pigments” should be understood as meaning white or coloured and inorganic or organic particles intended to colour and/or opacify the composition. The pigments in accordance with the invention can, for example, be chosen from white or coloured pigments or from pigments possessing special effects, such as pearlescent agents, reflective pigments or interference pigments. [0235] Mention may be made, as pigments which can be used in the invention, of titanium, zirconium or cerium oxides as well as zinc, iron or chromium oxides and ferric blue. Mention may be made, among the organic pigments which can be used in the invention, of carbon black and barium, strontium, calcium (D & C Red No. 7) and aluminium lakes. [0236] The pearlescent agents can be present in the composition in a proportion of 0.001 to 20% of the total weight of the composition, preferably at a level of the order of 1 to 15%. Mention may be made, among the pearlescent agents which can be used in the invention, of mica covered with titanium oxide, with iron oxide, with natural pigment or with bismuth oxychloride, such as coloured titanium oxide-coated mica. [0237] The pigments can be present in the composition in a proportion of 0.05 to 30% of the weight of the final composition and preferably in a proportion of 2 to 20%. [0238] The variety of the pigments which can be used in the present invention makes it possible to obtain a rich palette of colours and also specific optical effects, such as metallic or interference effects. [0239] The term “pigments possessing special effects” is understood to mean pigments which generally create a coloured appearance (characterized by a certain hue, a certain saturation and a certain lightness) which is non-uniform and which changes according to the conditions of observation (light, temperature, angles of observation, and the like). They consequently contrast with white or coloured pigments, which provide a conventional opaque, semitransparent or transparent uniform colouring. [0240] Mention may be made, as examples of pigments possessing special effects, of white pearlescent pigments, such as mica covered with titanium dioxide or with bismuth oxychloride, coloured pearlescent pigments, such as mica covered with titanium dioxide and with iron oxides, mica covered with titanium dioxide and in particular with ferric blue or with chromium oxide or mica covered with titanium dioxide and with an organic pigment as defined above, and pearlescent pigments based on bismuth oxychloride. Mention may be made, as pearlescent pigments, of the following pearlescent agents, Cellini, sold by Engelhard (mica-TiO 2 -lake), Prestige, sold by Eckart (mica-TiO 2 ), or Colorona, sold by Merck (mica-TiO 2 —Fe 2 O 3 ). [0241] Mention may also be made of pigments possessing an interference effect which are not attached to a substrate, such as liquid crystals (Helicones HC from Wacker) or holographic interference flakes (Geometric Pigments or Spectra f/x from Spectratek). Pigments possessing special effects also comprise fluorescent pigments, whether they be substances which are fluorescent in daylight or which produce ultraviolet fluorescence, phosphorescent pigments, photochromic pigments and thermochromic pigments. [0242] The composition advantageously comprises goniochromatic pigments, for example multilayer interference pigments, and/or reflective pigments. These two types of pigments are described in Application FR 0 209 246, the content of which is incorporated by reference in the present application. [0243] The composition can comprise reflective pigments which may or may not be goniochromatic pigments and which may or may not be interference pigments. [0244] Their size is compatible with the demonstration of a specular reflection of visible light (400-700 nm) of sufficient intensity, taking into account the mean gloss of the composition, to create a highlight point. This size is capable of varying according to the chemical nature of the particles, their shape and their capacity for specular reflection of visible light. [0245] The reflective particles will preferably exhibit a dimension of at least 10 μm, for example of between approximately 20 μm and approximately 50 μm. [0246] The term “dimension” denotes the dimension given by the statistical particle size distribution to half the population, referred to as D50. The size of the reflective particles can depend on their surface condition. The more reflective the latter, the smaller may a priori be the dimension, and vice versa. [0247] Reflective particles usable in the invention, possessing a metallic or white glint, can, for example, reflect the light in all the components of the visible region without significantly absorbing one or more wavelengths. The spectral reflectance of these reflective particles can, for example, be greater than 70% within the 400-700 nm range and better still at least 80%, indeed even 90% or also 95%. [0248] The reflective particles, whatever their shape, may or may not exhibit a multilayer structure and, in the case of a multilayer structure, may exhibit, for example, at least one layer of uniform thickness, in particular of a reflective material, which coats a substrate. [0249] The substrate can be chosen from glasses, ceramics, graphite, metal oxides, aluminas, silicas, silicates, in particular aluminosilicates and borosilicates, and synthetic mica, this list not being limiting. [0250] The reflective material can comprise a layer of metal or of a metal compound. [0251] The layer of metal or of metal compound may or may not completely coat the substrate and the layer of metal may be at least partially covered with a layer of another material, for example a transparent material. It may be preferable for the layer of metal or of metal compound to completely coat the substrate, directly or indirectly, that is to say with insertion of at least one intermediate metal or non-metal layer. [0252] The metal can be chosen, for example, from Ag, Au, Cu, Al, Ni, Sn, Mg, Cr, Mo, Ti, Pt, Va, Rb, W, Zn, Ge, Te, Se and their alloys. Ag, Au, Al, Zn, Ni, Mo, Cr, Cu and their alloys (for example, bronzes and brasses) are preferred metals. [0253] In the case in particular of particles possessing a substrate coated with silver or with gold, the metal layer can be present at a content representing, for example, from 0.1 to 50% of the total weight of the particles, indeed even between 1 and 20%. [0254] Particles of glass covered with a metal layer are described in particular in the documents JP-A-09188830, JP-A-10158450, JP-A-10158541, JP-A-07258460 and JP-A-05017710. [0255] Particles possessing a glass substrate coated with silver, in the form of platelets, are sold under the name Microglass Metashine REFSX 2025 PS by Toyal. Particles possessing a glass substrate coated with nickel/chromium/molybdenum alloy are sold under the name Crystal Star GF 550 or GF 2525 by this same company. [0256] The reflective particles, whatever their shape, can also be chosen from particles possessing a synthetic substrate at least partially coated with at least one layer of at least one metal compound, in particular a metal oxide, for example chosen from titanium oxides, in particular TiO 2 , iron oxides, in particular Fe 2 O 3 , tin oxides, chromium oxides, barium sulphate and the following compounds: MgF 2 , CrF 3 , ZnS, ZnSe, SiO 2 , Al 2 O 3 , MgO, Y 2 O 3 , SeO 3 , SiO, HfO 2 , ZrO 2 , CeO 2 , Nb 2 O 5 , Ta 2 O 5 MOS 2 and their mixtures or alloys. [0257] Mention may be made, as examples of such particles, for example, of particles comprising a substrate of synthetic mica coated with titanium dioxide or particles of glass coated either, on the one hand, with brown iron oxide or, on the other hand, with titanium oxide, with tin oxide or with one of their mixtures, such as those sold under the Reflecks brand by Engelhard. [0258] Pigments of the Metashine 1080R range, sold by Nippon Sheet Glass Co. Ltd., are also suitable for the invention. These pigments, more particularly described in Patent Application JP 2001-11340, are flakes of C-Glass glass comprising 65 to 72% of SiO 2 which are covered with a layer of titanium oxide of rutile (TiO 2 ) type. These glass flakes have a mean thickness of 1 micron and a mean size of 80 microns, i.e. a mean size/mean thickness ratio of 80. They exhibit blue, green, yellow or silver-coloured glints, depending on the thickness of the TiO 2 layer. [0259] Mention may also be made of particles with a dimension of between 80 and 100 μm comprising a substrate of synthetic mica (fluorophlogopite) coated with titanium dioxide representing 12% of the total weight of the particle, these particles being sold under the name Prominence by Nihon Koken. [0260] The reflective particles can also be chosen from particles formed of a stack of at least two layers possessing different refractive indices. These layers can be polymeric or metallic in nature and can in particular include at least one polymer layer. Such particles are described in particular in WO 99/36477, U.S. Pat. No. 6,299,979 and U.S. Pat. No. 6,387,498. Mention may be made, by way of illustration of the materials which can constitute the various layers of the multilayer structure, of, this list not being limiting: polyethylene naphthalate (PEN) and its isomers, poly(alkylene terephthalate)s and polyimides. Reflective particles comprising a stack of at least two layers of polymers are sold by 3M under the name Mirror Glitter. These particles comprise layers of 2,6-PEN and of poly(methyl methacrylate) in a ratio by weight of 80/20. Such particles are described in U.S. Pat. No. 5,825,643. [0261] The composition can comprise one or more goniochromatic pigments. [0262] The goniochromatic colouring agent can be chosen, for example, from multilayer interference structures and liquid crystal colouring agents. [0263] In the case of a multilayer structure, the latter can comprise, for example, at least two layers, each layer, independently or not independently of the other layer(s), being produced, for example, from at least one material chosen from the group consisting of the following materials: MgF 2 , CeF 3 , ZnS, ZnSe, Si, SiO 2 , Ge, Te, Fe 2 O 3 , Pt, Va, Al 2 O 3 , MgO, Y 2 O 3 , S 2 O 3 , SiO, HfO 2 , ZrO 2 , CeO 2 , Nb 2 O 5 , Ta 2 O 5 , TiO 2 , Ag, Al, Au, Cu, Rb, Ti, Ta, W, Zn, MoS 2 , cryolite, alloys, polymers and their combinations. [0264] The multilayer structure may or may not exhibit, with respect to a central layer, a symmetry with regard to the chemical nature of the stacked layers. [0265] Examples of symmetrical multilayer interference structures which can be used in are, for example, the following structures: Al/SiO 2 /Al/SiO 2 /Al, pigments having this structure being sold by DuPont de Nemours; Cr/MgF 2 /Al/MgF 2 /Cr, pigments having this structure being sold under the name Chromaflair by Flex; MOS 2 /SiO 2 /Al/SiO 2 /MoS 2 ; Fe 2 O 3 /SiO 2 /Al/SiO 2 /Fe 2 O 3 and Fe 2 O 3 /SiO 2 /Fe 2 O 3 /SiO 2 /Fe 2 O 3 , pigments having these structures being sold under the name Sicopearl by BASF; MoS 2 /SiO 2 /mica-oxide/SiO 2 /MoS 2 ; Fe 2 O 3 /SiO 2 /mica-oxide/SiO 2 /Fe 2 O 3 ; TiO 2 /SiO 2 /TiO 2 and TiO 2 /Al 2 O 3 /TiO 2 ; SnO/TiO 2 /SiO 2 /TiO 2 /SnO; Fe 2 O 3 /SiO 2 /Fe 2 O 3 ; SnO/mica/TiO 2 /SiO 2 /TiO 2 /mica/SnO, pigments having these structures being sold under the name Xirona by Merck (Darmstadt). By way of example, these pigments can be pigments with a silica/titanium oxide/tin oxide structure sold under the name Xirona Magic by Merck, pigments with a silica/brown iron oxide structure sold under the name Xirona Indian Summer by Merck and pigments with a silica/titanium oxide/mica/tin oxide structure sold under the name Xirona Caribbean Blue by Merck. Mention may also be made of the Infinite Colors pigments from Shiseido. Different effects are obtained according to the thickness and the nature of the various layers. Thus, with the structure Fe 2 O 3 /SiO 2 /Al/SiO 2 /Fe 2 O 3 , the colour changes from green-golden to red-grey for SiO 2 layers of 320 to 350 nm; from red to golden for SiO 2 layers of 380 to 400 nm; from purple to green for SiO 2 layers of 410 to 420 nm; and from copper to red for SiO 2 layers of 430 to 440 nm. [0266] Use may also be made of goniochromatic colouring agents possessing a multilayer structure comprising an alternation of polymer layers, for example of the polyethylene naphthalate and polyethylene terephthalate type. Such agents are described in particular in WO-A-96/19347 and WO-A-99/36478. [0267] Mention may be made, as examples of pigments possessing a polymeric multilayer structure, of those sold by 3M under the name Color Glitter. [0268] The liquid crystal colouring agents comprise, for example, silicones or cellulose ethers onto which mesomorphic groups are grafted. [0269] Use may be made, as liquid crystal goniochromatic particles, for example, of those sold by Chenix and of those sold under the name Helicone® HC by Wacker. [0270] The compositions according to the invention can be provided in any form acceptable and conventional for a cosmetic composition. [0271] A person skilled in the art can choose the appropriate formulation form, and its method of preparation, on the basis of his general knowledge, taking into account, on the one hand, the nature of the constituents used, in particular their solubility in the support, and, on the other hand, the application envisaged for the composition. [0272] The compositions in accordance with the invention can be used for caring for or making up keratinous substances, such as the hair, skin, eyelashes, eyebrows, nails, lips or scalp and more particularly for making up the lips, eyelashes and/or face. [0273] They can thus be provided in the form of a product for caring for and/or making up the skin of the body or face, lips, eyelashes, eyebrows, hair, scalp or nails; of an antisun or self-tanning product; of a hair product, in particular for colouring, conditioning and/or caring for the hair; they are advantageously provided in the form of a mascara, lipstick, lip gloss, face powder, eyeshadow or foundation. [0274] A further subject-matter of the invention is the use of two different polycondensates as described above, in particular in the proportions and the chemical compositions described above, for making up the lips in order to improve the fastness of the colour over time. [0275] A further subject-matter of the invention is a method for the cosmetic treatment of keratinous substances, in particular the skin of the body or face, lips, nails, hair and/or eyelashes, comprising the application, to the materials, of a cosmetic composition as defined above. [0276] This method according to the invention makes it possible in particular to care for or make up the lips by application of a lipstick or lip gloss composition according to the invention. [0277] The invention also relates to the use of the compositions described above for making up the lips. Another subject-matter of the present invention is a cosmetic combination comprising: a container delimiting at least one compartment, the container being closed by a closing element; and a composition as described above positioned inside the compartment. [0280] The container can have any appropriate form. It can in particular be in the form of a bottle, a tube, a pot, a box, a tin, a bag or a case. [0281] The closing element can be in the form of a removable stopper, of a lid, of a seal, of a tear-off strip or of a capsule, in particular of the type comprising a body fixed to the container and a cap articulated over the body. It can also be in the form of an element providing the selective closure of the container, in particular a pump, a valve or a flap. [0282] The container can be used in combination with an applicator, in particular in the form of a brush comprising an arrangement of hairs held by a twisted wire. Such a twisted brush is described in particular in U.S. Pat. No. 4,887,622. It can also be in the form of a comb comprising a plurality of application elements, obtained in particular from moulding. Such combs are described, for example, in Patent FR 2 796 529. The applicator can be in the form of a fine brush, such as described, for example, in Patent FR 2 722 380. The applicator can be in the form of a pad of foam or elastomer, of a felt-tipped pen or of a spatula. The applicator can be free (powder puff or sponge) or integrally attached to a rod carried by the closing element, such as described, for example, in U.S. Pat. No. 5,492,426. The applicator can be integrally attached to the container, such as described, for example, in Patent FR 2 761 959. [0283] The product may be contained directly in the container or indirectly. By way of example, the product can be positioned on an impregnated support, particularly in the form of a wipe or of a wad, and can be positioned (singly or severally) in a tin or in a bag. Such a support incorporating the product is described, for example, in Application WO 01/03538. [0284] The closing element can be coupled to the container by screwing. Alternatively, the coupling between the closing element and the container is carried out other than by screwing, in particular via a bayonet mechanism, by snapping, clamping, welding or adhesive bonding, or by magnetic attraction. The term “snapping” is understood to mean in particular any system involving the crossing of a row or strip of material by elastic deformation of a portion, in particular of the closing element, and then by elastically returning the portion to the unstressed position after the row or strip has been crossed. [0285] The container can be at least partially made of thermoplastic material. Mention may be made, as examples of thermoplastic materials, of polypropylene or polyethylene. [0286] Alternatively, the container is made of non-thermoplastic material, in particular of glass or of metal (or alloy). [0287] The container can have rigid walls or deformable walls, in particular in the form of a tube or of a tube bottle. [0288] The container can comprise means intended to bring about or facilitate the distribution of the composition. By way of example, the container can have deformable walls, so as to bring about the departure of the composition in response to excess pressurization inside the container, which excess pressurization is brought about by the elastic (or non-elastic) crushing of the walls of the container. Alternatively, in particular when the product is in the form of a stick, the latter can be driven by a piston mechanism. Still in the case of a stick, in particular of a make-up product (lipstick, foundation, and the like), the container can comprise a mechanism, in particular a rack-and-pinion mechanism or a mechanism with a screw rod or a mechanism with a helical groove, capable of moving a stick in the direction of the opening. Such a mechanism is described, for example, in Patent FR 2 806 273 or in Patent FR 2 775 566. Such a mechanism for a liquid product is described in Patent FR 2 727 609. [0289] The container can be composed of a case with a bottom delimiting at least one receptacle comprising the composition and a lid, in particular articulated over the bottom, capable of at least partially covering the bottom. Such a case is described, for example, in Application WO 03/018423 or in Patent FR 2 791 042. [0290] The container can be equipped with a drainer positioned in the vicinity of the opening of the container. Such a drainer makes it possible to wipe the applicator and optionally the rod to which it may be integrally attached. Such a drainer is described, for example, in Patent FR 2 792 618. [0291] The composition can be at atmospheric pressure inside the container (at ambient temperature) or pressurized, in particular using a propellant gas (aerosol). In the latter case, the container is equipped with a valve (of the type of those used for aerosols). [0292] The invention is illustrated in more detail in the following examples. Method for Measuring the Viscosity [0293] The viscosity at 80° C. or at 110° C. of the polymer is measured using a cone/plate viscometer of Brookfield CAP 1000+type. [0294] The appropriate cone/plate is determined by a person skilled in the art on the basis of his knowledge; in particular: between 50 and 500 mPa·s, use is made of a cone O 2 between 500 and 1000 mPa·s: cone 03 between 1000 and 4000 mPa·s: cone 05 between 4000 and 10 000 mPa·s: cone 06 Example 1 Synthesis of pentaerythrityl benzoate/isophthalate/isostearate [0299] 20 g of benzoic acid, 280 g of isostearic acid and 100 g of pentaerythritol are charged to a reactor equipped with a mechanical stirrer, an argon inlet and a distillation system and then the mixture is gradually heated, under a gentle argon stream, to 110-130° C. in order to obtain a homogeneous solution. The temperature is subsequently gradually increased up to 180° C. and this temperature is maintained for approximately 2 hours. The temperature is again increased up to 220° C. and this temperature is maintained until an acid number of less than or equal to 1 is obtained, which takes approximately 11 hours. The mixture is cooled to a temperature of between 100 and 130° C., then 100 g of isophthalic acid are introduced and the mixture is again gradually heated up to 220° C. for approximately 11 hours. [0300] 405 g of pentaerythrityl benzoate/isophthalate/isostearate polycondensate are thus obtained in the form of a very thick oil. [0301] The polycondensate exhibits the following characteristics: soluble to 50% by weight, at 25° C., in Parleam acid number=3.7 hydroxyl number=72 Mw=59 400 η 110° C. =1510 mPa·s ratio of the number of moles of aromatic monocarboxylic acid to the number of moles of nonaromatic branched monocarboxylic acid: 0.16. Example 2 Synthesis of pentaerythrityl benzoate/isophthalate/isostearate [0308] 35 g of benzoic acid, 270 g of isostearic acid and 80 g of pentaerythritol are charged to a reactor equipped with a mechanical stirrer, an argon inlet and a distillation system and then the mixture is gradually heated, under a gentle argon stream, to 110-130° C. in order to obtain a homogeneous solution. The temperature is subsequently gradually increased up to 180° C. and this temperature is maintained for approximately 2 hours. The temperature is again increased up to 220° C. and this temperature is maintained until an acid number of less than or equal to 1 is obtained, which takes approximately 11 hours.
