Abstract
A method for forming a coating film by sequentially forming a pigmented base coat and a clear top coat on a substrate. The pigmented base coat composition includes (1) an OH-containing resin, (2) an amino resin, (3) a polyorganosiloxane resin a number average molecule weight of at least 1,000 and having at least two groups per molecule selected from a silanol group and an alkoxysilane group and (4) a flaky metal or a mica powder in (5) an organic solvent. The clear top coat composition includes (1) an OH- and epoxy-containing base resin which additionally contains at least one of a silanol group and a hydrolyzable group bound directly to a silicon atom, (2) a curing catalyst and (3) an organic solvent.
