Abstract

Abstract This invention relates to a cosmetic film forming composition which is especially useful as a nail coating composition which upon drying forms a film which will adhere to keratin of a nail. More particularly, the present invention relates to cosmetic film forming compositions which consist of aqueous emulsion (A) which comprises a sulfopolyester and a copolymer of vinyl acetate and dialkyl maleate, and aqueous emulsion (B) which comprises an aqueous emulsion of acetoacetoxyethyl alkylacrylate or the reaction product of acetoacetoxyethyl alkylacrylate with a vinylfunctional monomer. These cosmetic film forming compositions are fast drying, have good adhesive properties and are environmentally compatible.

Claims Analysis

Total Claims: 11
Claim 1
Independent Claim 293 words
A cosmetic film forming composition comprising: (A) 30 to 85 weight percent of an aqueous emulsion comprising (1) 5 to 20 weight percent of a sulfopolyester consisting essentially of repeat units from (a) a dicarboxylic acid selected from the group consisting of aromatic dicarboxylic acids, saturated aliphatic dicarboxylic acids, cycloaliphatic dicarboxylic acids, and combinations thereof; (b) a diol, and (c) a difunctional sulfomonomer containing at least one sulfonate group attached to an aromatic nucleus wherein the functional groups are hydroxy, carboxy or amino, provided the difunctional sulfomonomer is present in an amount from 4 to 25 mole percent based on 100 mole percent dicarboxylic acid and 100 mole percent diol; and (2) 95 to 80 weight percent of a copolymer having repeat units from 50 to 90 weight percent vinyl acetate and 10 to 50 weight percent of a dialkyl maleate having the formula ##STR7## which is polymerized in an aqueous dispersion of the sulfopolyester; and (B) 15 to 70 weight percent of an aqueous emulsion containing acetoacetoxyethyl alkylacrylate having the formula: ##STR8## or a reaction product of acetoacetoxyethyl alkylacrylate with a vinylfunctional monomer selected from the group consisting of ##STR9## and mixtures thereof; provided that the total solids in the film forming composition is from 30 to 65 weight percent; wherein: R is a monovalent alkyl radical having 1 to 12 carbon atoms, R 1 is a monovalent alkyl radical having 1 to 4 carbon atoms, R 2 is selected from the group consisting of an alkyl radical having 1 to 20 carbon atoms, a substituted alkyl radical having 1 to 20 atoms, phenyl, substituted phenyl, cycloalkyl, furfuryl, and tetrahydrofurfural, and R 3 is independently selected from the group consisting of hydrogen and an alkyl radical having 1 to 4 carbon atoms.
Claim 2
Dependent Claim 293 words
A cosmetic film forming composition comprising: (A) 30 to 85 weight percent of an aqueous emulsion comprising (1) 5 to 20 weight percent of a sulfopolyester consisting essentially of repeat units from (a) a dicarboxylic acid selected from the group consisting of aromatic dicarboxylic acids, saturated aliphatic dicarboxylic acids, cycloaliphatic dicarboxylic acids, and combinations thereof; (b) a diol, and (c) a difunctional sulfomonomer containing at least one sulfonate group attached to an aromatic nucleus wherein the functional groups are hydroxy, carboxy or amino, provided the difunctional sulfomonomer is present in an amount from 4 to 25 mole percent based on 100 mole percent dicarboxylic acid and 100 mole percent diol; and (2) 95 to 80 weight percent of a copolymer having repeat units from 50 to 90 weight percent vinyl acetate and 10 to 50 weight percent of a dialkyl maleate having the formula ##STR7## which is polymerized in an aqueous dispersion of the sulfopolyester; and (B) 15 to 70 weight percent of an aqueous emulsion containing acetoacetoxyethyl alkylacrylate having the formula: ##STR8## or a reaction product of acetoacetoxyethyl alkylacrylate with a vinylfunctional monomer selected from the group consisting of ##STR9## and mixtures thereof; provided that the total solids in the film forming composition is from 30 to 65 weight percent; wherein: R is a monovalent alkyl radical having 1 to 12 carbon atoms, R 1 is a monovalent alkyl radical having 1 to 4 carbon atoms, R 2 is selected from the group consisting of an alkyl radical having 1 to 20 carbon atoms, a substituted alkyl radical having 1 to 20 atoms, phenyl, substituted phenyl, cycloalkyl, furfuryl, and tetrahydrofurfural, and R 3 is independently selected from the group consisting of hydrogen and an alkyl radical having 1 to 4 carbon atoms.
