Abstract:
An aqueous metallic coating composition comprising(A) 100 parts, based on solids, of a film-forming aqueous 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, the copolymer being obtained by copolymerizing (a) 10 to 35 wt. % of styrene, (b) 5 to 25 wt. % of C.sub.6-18 alkyl (meth)acrylate, (c) 0.1 to 10 wt. % of phosphoric ester group-containing polymerizable unsaturated monomer represented by the general formula ##STR7## wherein X is a hydrogen atom or methyl, and m is an integer of 1 to 3, (d) 2 to 10 wt. % of carboxyl-containing polymerizable unsaturated monomer, (e) 5 to 20 wt. % of hydroxyl-containing polymerizable unsaturated monomer, and (f) 0 to 77.9 wt. % of other polymerizable unsaturated monomer; and(B) 2 to 100 parts by weight of metallic flake pigment.
