Abstract
A water-based paint composition comprising (A) from 10-90% by weight, based on total weight of resin solids of a water-dispersible acrylic graft copolymer having an acid value of 10-30 mg and a hydroxyl value of 50-150, wherein the polymer is obtained by graft polymerization of an acrylic copolymer of an acid value of 35-120 mg KOH/g and a hydroxyl value 50-150 mg KOH/g, and an acrylic copolymer of acid value .ltoreq.15 and a hydroxyl value of 50-150, and (B) from 10-90% by weight, based on total weight of resin solids of internally non-crosslinked acrylic fine particles having an acid value 15-200 and a hydroxyl value of 15-200 made by emulsion polymerizing .alpha.,.beta.-ethylenically unsaturated monomers.
