Abstract

Anhydrous nail varnishes are disclosed which contain a copolymer of: PA1 (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 PA2 (a) H, in which case R.sub.3 represents: (i) --COOH (ii) --SO.sub.3 H ##STR2## or (vi) --COOR.sub.4, PA1 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 PA2 (b) --COOH, in which case R.sub.3 represents: PA3 (vii) --CO.sub.2 R.sub.5 or PA3 (viii) --CONHR.sub.5 PA1 R.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 ; PA1 (2) at least one methacrylate monomer of the formula: ##STR3## in which: R.sub.6 represents a linear or branched alkyl radical having up to 18 carbon atoms, or the radical ##STR4## and (3) at least one acrylate monomer of the formula: EQU CH.sub.2 .dbd.CH--CO…
