ABSTRACT:
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 aqueoux latex. The invention includes the latex paint so-produced.
