Abstract
Disclosed is a coating method comprising the steps of applying a base coat composition to a substrate, applying a clear coating composition to the coated surface while the applied base coat composition is still uncured and curing the two coating compositions thus applied at the same time, the method being characterized in that the base coat composition is an aqueous one containing a coloring pigment and that the clear coating composition is a curable one containing a basal resin and a curing catalyst as main components, the basal resin being a resin (Y) having in the molecule hydroxyl group and/or hydrolyzable group both directly attached to the silicon atom, and epoxy group or a resin mixture (Z) of a resin or a compound (Z-1) having hydroxyl group and/or hydrolyzable group both directly attached to the silicon atom and a resin (Z-2) having epoxy group.
