The present invention provides an thermosetting aqueous coating composition comprising (A) 100 parts by weight of a hydroxy- and carboxy-containing water-soluble resin having a weight average molecular weight of 500 to 200,000, a hydroxy value of 1 to 200 mg KOH/g, and an acid value of 10 to 100 mg KOH/g, and (B) 10 to 100 parts by weight of a luster pigment; the coating composition being applied so as to form a film with a thickness of 3,000 to 8,000 nm when cured; and the coating composition, when formed into a deposited coating with a solids content of 40 wt.%, having a viscosity of 4 x 102 to 1 x 104 mPa·s as measured at 20°C and a shear rate of 0.1 sec-1.
The present invention discloses a thermosetting aqueous paint, comprising an oligomer (A-1), having a specific acid value, hydroxyl value and number average molecular weight, and obtained by reacting a compound having at least one hydroxyl group and at least one carboxyl group in a molecule thereof, a monoepoxide compound having a long-chain hydrocarbon group, and as necessary, a polyvalent carboxylic acid and/or polyvalent carboxylic acid anhydride, and/or a polyester resin (A-2) obtained by further reacting a polyvalent carboxylic acid and/or a polyvalent carboxylic acid anhydride and/or a polyisocyanate compound with the oligomer, and a crosslinking agent (B); and also discloses a method for forming a paint film using this paint.
