Claims Analysis
Total Claims: 25
Claim 1
Independent Claim
207 words
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 polymer having a solids content from about 30 to about 55 percent, the polymer having a T g within the range of about -10° C. to about 50° C. when measured by differential thermal analysis and being prepared by an aqueous emulsion polymerization of two or more of the following monomers, at least one of which is of formula I or formula II; ##STR8## wherein R is C 1 -C 20 alkyl, phenyl, benzyl, hydroxy-(C 1 -C 4 )-alkyl, C 1 -C 4 alkoxy-(C 1 -C 4 )alkyl, cyclopentyl, cyclohexyl, furyl, C 1 -C 4 alkylfuryl, tetrahydrofuryl, or C 1 -C 4 alkyltetrahydrofuryl; R 1 is hydrogen or methyl; and R 2 is hydrogen or C 1 -C 3 alkyl, subject to the limitation that when R in one of the monomers is C 1 -C 4 alkoxy-(C 1 -C 4 )alkyl, then R in the other monomer is a group other than C 1 -C 4 alkoxy-(C 1 -C 4 )alkyl or hydroxy-(C 1 -C 4 )alkyl.
