PURPOSE:To provide a water-based coating composition excellent in drying property, gloss and film properties, prepared by mixing a specified aqueous emulsion of oxidation-polymerized copolymer with an aqueous solution or dispersion of an oxidation-polymerized resin. CONSTITUTION:The water-based coating composition is prepared by mixing an aqueous emulsion of an oxidation-polymerized copolymer with an aqueous solution or dispersion of an oxidation-polymerized resin. The oxidation-polymerized copolymer is prepared by emulsion polymerization of 2-60pts.wt. monomer having an air-drying double bond selected from among unsaturated polyester compds. obtained by reacting alpha,beta-ethylenically unsaturated dicarboxylic acid (anhydride) with a reaction product of (semi) drying oil fatty acid and alpha,beta- ethylenically unsaturated aziridinyl alkyl ester and a reaction product of (semi) drying oil and polyhydric alcohol, and 98-40pts.wt. copolymerizable alpha,beta-ethylenically unsaturated monomer.
