<p>A water-base metallic paint composition comprising (A) 100 parts by weight (solid content) of a film-forming water-base acrylic polymer obtained by neutralizing a copolymer having a number-average molecular weight of 2,000 to 200,000 an acid value of 10 to 110 mg KOH/g, and a hydroxyl value of 20 to 100 mg KOH/g, and obtained by copolymerizing (a) 10 to 35 % by weight of styrene, (b) 5 to 25 % by weight of alkyl (meth)acrylate having 6 to 18 carbon atoms, (c) 0.1 to 10 % by weight of a polymerizable unsaturated monomer containing a phosphate group and represented by general formula (I), wherein X represents a hydrogen atom or a methyl group, and m represents an integer from 1 to 3, (d) 2 to 10 % by weight of a polymerizable unsaturated monomer containing a carboxylic group, (e) 5 to 20 % by weight of a polymerizable unsaturated monomer containing a hydroxyl group, and (f) 0 to 77.9 % by weight of another polymerizable unsaturated monomer and (B) 2 to 100 parts by weight of a scaly metallic pigment; and a method of forming an overcoat from the composition.</p> |
