Claim Text:
1. A nail polish composition, comprising: a. at least one high gloss film forming agent chosen from (1) an esterified styrene maleic anhydride copolymer selected from mixed methyl and isobutyl partial ester copolymers, (2) a non-esterified styrene maleic anhydride copolymer, and mixtures thereof, each of said copolymers having a styrene/maleic anhydride monomer molar ratio of from 1:2 to 2:1, and mixtures thereof, said film forming agent being present in an amount from about 10% to about 20% by weight of the total composition, having a molecular weight from about 5,000 to about 200,000 and having a Tg ranging from about 125° C. to about 160° C.; b. a tosylamide epoxy resin having a Tg of less than about 80° C. and being present in an amount ranging from about 11% to about 20% of the total weight of the composition; c. at least one plasticizer being present in an amount of from about 1% to about 20% by weight, based on the total weight of the composition; d. at least one solvent, said solvent being present in an amount of from about 10% to about 80% by weight, based on the total weight of the composition; and e. optionally, at least one colorant; wherein the weight ratio of the high gloss film forming agent to the at least one co-film forming agent is from about 1 to 1 to about 2 to 1, said composition having a gloss value of at least 80 at angles of 20° and 60° and containing about 0% nitrocellulose.
