Method for forming multi-layer metallic coating film

Disclosed is an aqueous resin dispersion prepared by dispersing in an aqueous medium a graft resin (A) and a hydrophobic melamine resin (B), said graft resin (A) having a weight average molecular weight of 10,000 to 100,000 and an acid value of 5 to 80, and consisting of a hydrophobic main chain moiety and a hydrophilic side chain moiety, said hydrophilic side chain moiety being 5,000 to 50,000 in weight average molecular weight and at least 20 in acid value.

Aqueous resin dispersion

Disclosed are (1) a water-dispersible resin composition prepared by a process comprising; (I) reacting a silane monomer (A) having hydrolytic functional group and/or silano group and polymerizable unsaturated bond with a vinyl monomer (B) in an aqueous medium to obtain a three-dimensionally crosslinked particulate polymer, (II) reacting the particulate polymer with the silane monomer (A) and/or an allyl acrylate or allyl methacrylate (C), and (III) copolymerizing the resulting reaction product with a vinyl monomer component comprising a carboxyl-containing vinyl monomer (D), followed by neutralizing the carboxyl group; (2) a water-dispersible coating composition comprising a crosslinking agent and the water-dispersible resin composition prepared using a hydroxyl-containing vinyl monomer and another vinyl monomer as the vinyl monomer (B) in the step (I), and (3) a coating method characterized by using as a base coat composition a water-dispersible coating composition comprising the foregoing water-dispersible coating composition and a coloring pigment and/or metallic pigment in the two-coat method.
