Abstract
A process for forming a coating with a metallic finish, which comprises PA1 (1) a first step of coating an article with [A] a water-thinnable paint comprising (a) a cross-linkable (meth)acrylate ester copolymer or a mixture of the (meth)acrylate ester copolymers containing at least 0.1 equivalent, per 1,000 g of resin solids, of a carboxyl or carboxyl ion group and a group capable of undergoing a ring-opening reaction with the carboxyl or carboxy ion group upon heating, both of said groups being contained in the same or different copolymers, and having a number average molecular weight of at least 3,000 and (b) metallic scales, and baking the coating paint to form a coating containing the metallic scales and PA1 (2) a second step of coating [B] a powder paint comprising a (meth)acrylate ester copolymer having a glycidyl or .beta.-methylglycidyl group and a polycarboxylic acid on the scale-containing coating obtained in the first step, and baking the coated paint to form a protective coating for the scale-containing coating.
