Abstract
The present invention provides a method for film formation, which comprises applying onto a substrate an electrocoating (A) and an intermediate coating (B) in this order, heat-curing the formed films of the coatings (A) and (B), applying thereon a liquid light color coating (C), the liquid light color coating (C) forming a color film having an L value of 30-95 in the Lab color system, which comprises 100 parts by weight of a thermosetting resin composition, 0.1-30 parts by weight of a fine aluminum powder having an average particle diameter of less than 10.mu. and 1-200 parts by weight of a titanium oxide pigment and which shows a film hiding power of 25.mu. or less and a film elongation ratio of 10-50% at 20.degree. C., a liquid metallic coating (D) which comprises 100 parts by weight of a thermosetting resin composition and 0.1-20 parts by weight of a metallic pigment having an average particle diameter of 3.mu. or more and which shows a film hiding power of 50.mu. or more and a film elongation ratio of 10% or less at 20.degree. C., and a clear coating (E) in this order on a wet-on-wet basis, and heating the formed films of the coatings (C), (D) and (E) to crosslink and cure the …
