Abstract
An aqueous coating composition constitutes an aqueous graft copolymer and an amino resin, the graft copolymer being obtained by neutralizing, with a base, the carboxyl groups of a copolymer which is obtained by copolymerizing the following components (a), (b), (c) and (d) and which contains 3-30% of component (a), 3-20% of component (b), 5-40% of component (c) and 10-89% of component (d): PA1 (a) a radical-polymerizable polyester compound having a (meth)acryloyl group at one end, preferably a macromolecular monomer which is a copolymer of a hydroxyalkyl (meth)acrylate and another .alpha.,.beta.-ethylenically unsaturated monomer, having a radical-polymerizable group at one end, PA1 (b) an .alpha.,.beta.-ethylenically unsaturated carboxylic acid, PA1 (c) a hydroxyalkyl (meth)acrylate, and PA1 (d) another vinyl monomer.
