Abstract
Vinyl acetate based aqueous dispersion having improved wet adhesion properties are prepared by copolymerizing vinyl acetate with about 3 to about 10 percent by weight of a polyacrylate ester and about 0.5 to 3 percent by weight of hydroxymethyl diacetone acrylamide, said percentages being based on the total weight of the copolymer. Optionally, other monomers copolymerizable therewith can be included in the copolymer. Aqueous dispersions of this invention have utility as vehicles in protective coating formulations.
