Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
97 words
A method of forming a cured composition comprising; (a) forming a composition comprising an aqueous dispersion of a vinyl addition polymer and about 1% to about 200% by weight, based on the weight of said polymer, of a reactive coalescent of formula II ##STR3## wherein R is a monovalent or polyvalent organic radical, X is an integer from 1 to 6 whose value is equal to the valence of the organic radical R and R 1 is hydrogen or C 1 -C 22 alkyl; and (b) exposing said composition to the air for at least 28 days.
Claim 2
Independent Claim
97 words
A method of forming a cured composition comprising; (a) forming a composition comprising an aqueous dispersion of a vinyl addition polymer and about 1% to about 200% by weight, based on the weight of said polymer, of a reactive coalescent of formula II ##STR3## wherein R is a monovalent or polyvalent organic radical, X is an integer from 1 to 6 whose value is equal to the valence of the organic radical R and R 1 is hydrogen or C 1 -C 22 alkyl; and (b) exposing said composition to the air for at least 28 days.
Claim 3
Independent Claim
102 words
A method of forming a cured composition comprising; (a) forming a composition comprising an aqueous dispersion of a vinyl addition polymer and about 1% to about 200% by weight, based on the weight of said polymer, of a reactive coalescent of formula II ##STR4## wherein R is a monovalent or polyvalent organic radical, X is an integer from 1 to 6 whose value is equal to the valence of the organic radical R and R 1 is hydrogen or C 1 -C 22 alkyl; and (b) exposing said composition to light with a wavelength of about 200 nanometers to about 400 nanometers.
