Abstract
A cationic electrodeposition paint composition suitable for a wheel of an automotive vehicle. The paint composition contains an amine-modified epoxy resin and a blocked isocyanate as main components. The paint composition further contains a nonionic emulsified and dispersed type acrylic resin within a range from 6 to 30% by weight in resinous solid content relative to the total resin content of the paint composition, a colloidal silica-containing gelled particulate within a range from 10 to 30 PHR in solid content in paint composition, and an alkyltin ester compound of an aliphatic carboxylic acid within a range from 0.1 to 10 PHR in solid content in the paint composition, thereby improving corrosion resistance of an edge portion of the wheel and a weatherability of a paint film coated on the surface of the steel plate of the wheel.
