Vinyl acetate polymer with wet adhesion

An aqueous coating composition having wet adhesion properties, which comprises a blend of two different aqueous film-forming copolymer dispersions in which the copolymer particles have different average particle size ranges and consisting essentially of:

• (a) about 1 to about 50 wt % of a first of said two different film-forming copolymer dispersions wherein the copolymer particles have an average particle size of from about 50 to about 200 nm, said copolymer particles of said first film-forming copolymer dispersion comprising the copolymeric product formed by copolymerization of a first copolymerizable mixture of monomers which includes a wet adhesion-imparting quantity of an unsaturated wet adhesion property imparting cyclic ureido monomer, and
• (b) about 99 to about 50 wt % of a second of said two different film-forming copolymer dispersions wherein the copolymer particles have an average particle size of about 300 to about 700 nm, said copolymer particles of said second film-forming copolymer dispersion comprising the copolymeric product formed by copolymerization of a second copolymerizable mixture of monomers from which said unsaturated wet adhesion property imparting cyclic ureido monomer is absent,
• wherein said cyclic ureido monomer is present in said blend, in copolymerized form and only in the first polymer dispersion, in an amount of about 0.01 to about 0.25 wt % of total monomer present in polymerized form in said first and second film-forming copolymer dispersions in said blend.
