    摘要: The present invention provides a process of a forming multilayer coating film characterized by that in a process of forming a multilayer coating film by successively coating with an undercoat paint (A), an intermediate paint (B) and a topcoat paint (C) on a substrate, (1) to use a liquid thermocurable paint containing 0.1-30 parts by weight of aluminium powder and 1-200 parts by weight of titanium oxide pigment per 100 parts by weight of a thermosetting resin composition and the hiding film thickness of its coating film being less than 25 &mgr;m as said intermediate paint (B), (2) to use a solid color paint, a metallic paint or an interference pattern paint as said topcoat paint (C), and (3) to coat said topcoat paint (C) after curing by heating of the coating film of said intermediate paint (B). By this process it is possible to make an intermediate coating film thinner and to form a multilayer coating film with excellent smoothness.
