ABSTRACT:
An aqueous coating composition for the manufacture of precoated metal is based on an aqueous resin having a carboxyl group in a molecule and neutralizable with a basic material as a binder, the aqueous resin being selected from an acrylic copolymer resin, polyester resin, and polyurethane resin. A mono- or poly-carbodiimide compound is blended with the aqueous resin. The composition forms a coating having improved chemical resistance, water resistance, and adhesion to sheet metal.
