Claim:
1. A cosmetic composition for application to the nails comprising: (a) from about 6% to about 20%, by dry weight, of at least one photo-curable polymer dispersed in water; (b) greater than about 8%, by dry weight, of at least one non-photo-curable polymer dispersed in water; (c) less than or equal to about 2% by weight of at least one photo-initiator; (d) from about 0% to about 8% by weight of at least one plasticizer; (e) optionally a colorant; and (f) from about 40% to about 70% water; wherein the ratio, by dry polymer weight, of the at least one photo-curable polymer (a) to the at least one non-photo-curable polymer (b) is from 4:1 to 1:5, and the sum, by dry polymer weight percent, of the photo-curable polymer (a) plus the non-photo-curable polymer (b) is from about 25% to about 40%; all weights being relative the total weight of the composition, wherein the at least one non-photo-curable polymer dispersed in water (b) has at least one low glass transition temperature (Tg), wherein the photo-curable polymer dispersed in water (a) has a number average molecular weight from about 10,100 Mn to about 500,000 Mn, and wherein the photo-curable polymer dispersed in water (a) is selected from an aliphatic urethane acrylic copolymer, an aliphatic anionic polyurethane dispersion, an aromatic polyurethane dispersion, and mixtures thereof.
