Pigmented latex paints having superior gloss prepared by grinding a pigment into a solution of a copolymer of an unsaturated carboxylic acid

摘要

A high gloss, water base, pigmented latex is provided by grinding a pigment into a water-free solution of a carboxyl-functional addition copolymer of monoethylenically unsaturated monomers including at least about 3% by weight of monoethylenically unsaturated carboxylic acid in water miscible organic solvent, the copolymer being at least partially neutralized with an amine, particularly an hydroxy amine, to render the said copolymer dispersible in water, and thereby form a nonaqueous pigment paste, and then mixing the nonaqueous pigment paste with an aqueous latex. The invention includes the latex paint so-produced.
