Claim 2
Dependent Claim
81 words
A composition adapted to coat or impregnate a substrate 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.
Claim 3
Dependent Claim
98 words
A composition adapted to coat or impregnate a substrate 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; further comprising about 0.0005% to about 2% by weight drier based on the weight said reactive coalescent.
Claim 4
Dependent Claim
