An aqueous coating composition comprising (A) an aqueous dispersing material which is a copolymer having a glass transition temperature (Tg) of 80.degree. C. or less which is obtained by the copolymerization a specific unsaturated carboxylic acid, (meth)acrylic acid alkyl ester, and other monomers and (B) a specific aminoalcohol compound in a specific proportion.
