Abstract

A method of forming a multilayered coating film by applying a cationic electrodeposition coating material containing a blocked polyisocyanate compound as a cross-linking agent, applying a water-based intercoating material containing a blocked polyisocyanate compound as a cross-linking agent on the electrodeposited coating film to form an intercoating film without curing the electrodeposited coating film, and heating the two coating films to simultaneously cure both, characterized by regulating the coating materials so that the cross-linking curing reaction of the electrodeposited coating film begins earlier than that of the intercoating film. This method can give a multilayered coating film improved in finish appearance (smothness, gloss, etc.), interlaminar adhesion between the coating films, etc.
