Abstract: Nail lacquer compositions comprising a polymer resin consisting essentially of units resulting from the copolymerization of:(1) 75 to 97% by weight of at least one monomer having the general formula: ##STR1## in which: R.sub.1 represents an hydrogen atom or a methyl radical, andR.sub.2 represents a linear alkyl radical or a branched radical having 1 to 18 carbon atoms, a mono or dihydroxy alkyl radical, the alkyl radical having from 2 to 4 carbon atoms, a glycidyl radical or the radical --(CH.sub.2).sub.n --OR', wherein R' represents methyl or ethyl and n is 3 or 4, and(2) 3 to 25% by weight of at least one monomer selected from the group consisting of N-vinylsulfonamide, 4-styrenesulfonamide, acrylamide, methacrylamide, N-(N'N',3-dimethylaminopropyl) methacrylamide and N-(N'N',3-dimethylaminopropyl) acrylamide.

Abstract: A cosmetic makeup composition contains in an appropriate cosmetically acceptable vehicle or carrier a colored pigment resulting from the salification reaction of a polymer having salified primary or secondary amine functions or quaternized tertiary amine functions and an acid dye, in free acid form or as a salt thereof, the acid dye being fixed on said polymer in an amount of at least 10 weight percent of the stoichiometric quantity.The compositions include lip rouges, cheek rouges, foundation creams and nail enamels.

Abstract: The present invention concerns new acid colorant and copolymer salts carrying tertiary amine functions, the process for preparing said salts, as well as the makeup compositions and in particular the lipsticks and nail varnishes containing as coloring substances the saits according to the invention.

Abstract: Anhydrous nail varnishes are disclosed which contain a copolymer of:(1) at least one unsaturated polar monomer of the formula: ##STR1## in which: R.sub.1 represents H, --CH.sub.3 or --CH.sub.2 COOH; such that if R.sub.1 represents H, R.sub.2 represents either(a) H, in which case R.sub.3 represents:(i) --COOH(ii) --SO.sub.3 H ##STR2## or (vi) --COOR.sub.4,R.sub.4 representing a glycidyl radical, a mono- or di-hydroxy-alkyl radical, the alkyl radical having from 2 to 4 carbon atoms, or the radical --(CH.sub.2 --CH.sub.2 --C)l--R', R' representing a methyl or ethyl radical and l representing 3 or 4, or(b) --COOH, in which case R.sub.3 represents:(vii) --CO.sub.2 R.sub.5 or(viii) --CONHR.sub.5R.sub.5 representing H or an alkyl radical having from 1 to 4 carbon atoms; and if R.sub.1 represents --CH.sub.3 or --CH.sub.2 COOH, R.sub.2 represents H and R.sub.3 represents --COOH or --COOR.sub.4 ;(2) at least one methacrylate monomer of the formula: ##STR3## in which: R.sub.
