Abstract
The present invention provides a process for forming a multilayer film, which comprises: applying a cationic electrocoating (A) and an intermediate coating (B) in this order, followed by heat-curing, applying thereon a coloring base coating (C) capable of forming a colored film having a value of N 7 to N 9 in Munsell's color system, applying, without curing the coloring base coating (C) applied above, an iridescent base coating (D) containing a scaly mica powder coated with titanium oxide, followed by preliminary drying at 50.degree.-100.degree. C., and applying a clear coating (E), followed by heating to subject the films of the coatings (C), (D) and (E) simultaneously to crosslinking and curing, wherein the coloring base coating (C) and the iridescent base coating (D) are each a thermosetting aqueous coating containing, as vehicle components, an acrylic resin emulsion (a), a urethane resin emulsion (b) and a crosslinking agent (c). The process can form a multilayer film superior in iridescence feeling, depth feeling, smoothness, distinctness of image gloss, etc. and is suitably used for coating of, in particular, automobile body panel.
