Abstract

An aqueous coating composition comprising (A) an aqueous dispersing material which is a copolymer having a glass transition temperature (Tg) of 80° 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. The aqueous coating composition is safe due to absence of heavy metals, produces excellent gloss and has a fine external appearance when coated, and exhibits superior durability and water resistance which are represented by black heel mark resistance and anti-scuff properties. The composition is particularly useful as a floor coating material.
