Abstract
Disclosed is an aqueous coating composition characterized in that the composition consists essentially of: PA0 (A) a resin for use in aqueous coating compositions, PA0 (B) a urethane resin emulsion, and PA0 (C) crosslinking agent, PA0 the component (B) being an aqueous dispersion of a polyurethane resin prepared by reacting (a) an aliphatic polyisocyanate and/or an alicyclic polyisocyanate, (b) a high-molecular-weight polyol, (c) an .alpha.,.alpha.-dimethylolmonocarboxylic acid, and when required, (d) a chain lengthening agent and/or a polymerization terminator, and subsequently neutralizing the carboxyl with (e) a primary monoamine and/or a secondary monoamine.
