PRODUIT COSMETIQUE. CE PRODUIT EST CARACTERISE PAR LE FAIT QU'IL CONTIENT DANS UN SYSTEME SOLVANT POUR VERNIS UNE RESINE ESSENTIELLEMENT CONSTITUEE PAR COPOLYMERE RESULTANT DE LA COPOLYMERISATION: 1D'AU MOINS UN MONOMERE DE FORMULE:(CF DESSIN DANS BOPI)DANS LAQUELLE R REPRESENTE NOTAMMENT H,R REPRESENTE NOTAMMENT HET R REPRESENTE ALORS NOTAMMENT:(CF DESSIN DANS BOPI) 2D'AU MOINS UN METHACRYLATE D'ALKYLE OU DE DIMETHYLAMINOETHYLE; 3D'AU MOINS UN ACRYLATE D'ALKYLE. APPLICATION AU VERNISSAGE DES ONGLES. Anhydrous nail varnishes are disclosed which contain a copolymer of: (1) at least one unsaturated polar monomer of the formula: (I) in which: R1 represents H, -CH3 or -CH2COOH; such that if R1 represents H, R2 represents either (a) H, in which case R3 represents: (i) -COOH (ii) -SO3H +R1, (iii) (iv) (v) or (vi) -COOR4, R4 representing a glycidyl radical, a mono- or di-hydroxy-alkyl radical, the alkyl radical having from 2 to 4 carbon atoms, or the radical -(CH2-CH2-C)l-R', R' representing a methyl or ethyl radical and l representing 3 or 4, or (b) -COOH, in which case R3 represents: (vii) -CO2R5 or (viii) -CONHR5 R5 representing H or an alkyl radical having from 1 to 4 carbon atoms; and if R1 represents -CH3 or -CH2COOH, R2 represents H and R3 represents -COOH or -COOR4; (2) at least one methacrylate monomer of the formula: (II) in which: R6 represents a linear or branched alkyl radical having up to 18 carbon atoms, or the radical and (3) at least one acrylate monomer of the formula: CH2=CH-COOR7 (III) in which: R7 represents a linear or branched alkyl radical having up to 18 carbon atoms, or a quaternary derivative thereof.
