International ClassesC08L 027/06C08L 039/04 827 832 833 AbstractWet adhesion, ICI viscosity, and scrub resistance of a paint are improved by incorporating into the paint a binder that comprises a film former and polymeric composition. The polymeric composition comprises either (a) about 15 to about 35 weight percent of substantially non-self-polymerizable monomer, about 30 to about 70 weight percent of a copolymerizable monomer whose homopolymer is water-soluble, and about 10 to about 35 weight percent of a wet adhesion promoting monomer, or (b) about 35 to about 65 weight percent of the substantially non-self-polymerizable monomer and about 35 to about 65 weight percent of the wet adhesion promoting monomer. The polymeric composition and film former are substantially inseparable by chromatographic means.Other References
