<p>The invention provides: A method of forming a coating film by forming in sequence a pigmented base coat and a clear top coat on a substrate followed by finishing by the two-coat one-bake technique, the method being characterized by using, as a coating composition for pigmented base coat formation, a composition comprising, as essential components thereof, (1) an OH-containing resin, (2) an amino resin, (3) a polyorganosiloxane which has, on an average, at least two groups, per molecule, each selected from the class consisting of a silanol group and an alkoxysilane group and has a number average molecular weight of at least 1,000, (4) a flaky metal powder and/or a mica powder, and (5) an organic solvent, and using, as a coating composition for clear top coat formation, a composition comprising, as essential components thereof, (1) an OH- and epoxy-containing base resin which further contains at least one group selected from the group consisting of a silanol group and a hydrolyzable group bound directly to a silicon atom, (2) a curing catalyst, and (3) an organic solvent. </p> |
