A nail coating formulation which upon drying forms a film which will adhere to keratin of the nail and has a moisture vapor transmission from about 0.1 to about 1.6 mg./cm.<2>/hr., said formulation comprising an aqueous emulsion of a copolymer having a solids content of from about 30 to about 55 percent, the copolymer having a glass transition temperature within the range of about -10 DEG C. to about 50 DEG C. as determined by differential thermal analysis and being prepared by the aqueous emulsion polymerization of two or more of the following monomers, at least one of which is of formula I or formula II;
<CHEM>
wherein R is C1-C20 alkyl, phenyl, benzyl, hydroxy- (C1-C4)-alkyl, C1-C4 alkoxy- (C1-C4) alkyl, cyclopentyl, cyclohexyl, furyl, C1-C4 alkylfuryl, tetrahydrofuryl, or C1-C4 alkyltetrahydrofufyl; R<1> is hydrogen or methyl; and R<2> is hydrogen or C1-C3 alkyl, subject to the limitation that when R is one of monomers is C1-C4 alkoxy- (C1-C4) alkyl, then R in the other monomer is a group other than C1-C4 alkoxy- (C1-C4) alkyl or hydroxy- (C1-C4) alkyl.
