Abstract
The present invention relates to a two coat one bake coating method in which the aqueous base coating composition and the powder clear coating composition are applied onto substrates in automobile painting processes. In accordance with the present invention, the aqueous base coat contains: (a) a vinyl polymer prepared by copolymerizing 8 to 30% by weight of an amido group containing ethylenic monomer, an acidic group containing ethylenic monomer, a hydroxyl group containing ethylenic monomer and at least one other ethylenic monomer; (b) an aqueous dispersion of hydrophilic group containing oligomers; and (c) pigment. The clear powder coating composition comprises an epoxy group containing acrylic resin, and may carry polymer microparticles on each powder particle.
