Abstract (en)
There is disclosed a method of forming a multilayered coating film by coating a cationic electrodeposition paint, containing a blocked polyisocyanate compound as a crosslinking agent, forming an intermediate coating film by coating a water-based intermediate paint, containing a blocked polyisocyanate compound as a cross-linking agent, on the formed, electrodeposited coating film without curing said electrodeposited coating film, and then heating both coating films to form a multilayered coating film by curing both together, characterized by regulating so that the crosslinking curing reaction of said electrodeposited coating film starts earlier than the crosslinking curing reaction of said intermediate coating film. According to the method the finish appearance (smoothness, gloss etc.), interlaminar adhesion between both coating films of the multilayered coating film can be improved.
