Abstract
The present invention provides a method for forming a topcoat which comprises applying an aqueous colored base coating composition comprising a hydroxyl- and carboxyl-containing acrylic resin, a melamine resin, an alicyclic epoxy-containing compound, a neutralizing agent, and a coloring pigment to a substrate and applying to the base coat an organic solvent type clear coating composition to be cured by the crosslinking reaction between a carboxyl group and an epoxy group.
