Abstract
A cationic electrodeposition paint composition suitable to be coated on a road wheel of an automotive vehicle. The paint composition is composed of an acrylic cationic resin (A), a urethanated epoxy cationic resin (B) a hardner resin (C) of a blocked isocyanate, and a cationic cross-linked resin particulate (D) having an average particle size ranging from 0.01.mu. to 1.mu.. In the paint composition the acrylic cationic resin (A), the urethanated epoxy system cationic resin (B), the blocked isocyanate hardner resin (C) and the cationic cross-linked resin particulate are respectively in amount of 20 to 70 parts by weight, 5 to 50 parts by weight, 10 to 40 parts by weight and 1 to 20 parts by weight relative to 100 parts by weight of a total solid content of the resins and particulate (A), (B), (C) and (D), thereby improving the corrosion resistance of the paint composition to the cut edge portion of the road wheel and the weatherability of coated paint film.
