Abstract
Wet adhesion properties comparable or superior to all-acrylic latexes for vinyl acetate copolymers and other low cost polymers, such as EVA-vinyl chloride copolymers, is achieved by blending a minor proportion, usually about 5 to 15%, of a small particle size copolymer containing copolymerized wet adhesion monomer which is a cyclic ureido. Very low quantities of the wet adhesion monomer, less than 0.25 wt% of total monomers, only are required to achieve excellent results.
