Abstract
The present invention provides a process for forming a multilayer film by applying, on a substrate, the following coatings in the following order: (A) a primer, (B) an intermediate coating, C) a coloring base coating, (D a pearl-like base coating, and (E) a clear coating, in which process the intermediate coating (B) is a liquid thermosetting coating containing a thermosetting resin composition, a fine aluminum powder having an average particle diameter of less than 10 .mu.m and a titanium oxide pigment, the amounts of the fine aluminum powder and the titanium oxide pigment being 0.1-30 parts by weight and 1-200 parts by weight, respectively, per 100 parts by weight of the thermosetting resin composition so that a film formed from the liquid thermosetting coating has a hiding powder of 25 .mu.m or less; the coloring base coating (C) is a coating containing a thermosetting resin composition, a titanium white pigment and an aluminum flake, the amounts of the titanium white pigment and the aluminum flake being such that a film formed from the coating has a value of N 7 to N 9 in Munsell's color system; and the pearl-like base coating (D) is a white-pearl-like or silver-pearl-like coating containing a thermosetting resin composition and a scaly mica powder coated with titanium oxide. The process enables formation of a multilayer film superior in chipping resistance, high white-iridescent appearance, color stability, etc. even when having a small total film thickness.
