Aqueous dispersion of keto- and phosphorus acid monomer-functionalized polymer particles
The present invention is related to a coating composition comprising a) an aqueous dispersion of acrylic or styrene-acrylic polymer particles functionalized with structural units of a monomer with keto functionality and structural units of a phosphorus acid monomer; b) a dispersant comprising structural units of a carboxylic acid monomer and a monomer with keto functionality; and c) a dihydrazide crosslinking agent. The composition of the present invention is useful for improving scrub resistance in a coating formed from the composition.
