Abstract

The present invention provides an aqueous emulsion composition excellent in heat resistance, water resistance, hot water resistance, boiling water resistance, and viscosity stability and also excellent in stain resistance. The present invention relates to an aqueous emulsion composition including an aqueous emulsion (D) and a cyclic acid anhydride (E). The aqueous emulsion (D) includes a polymer (X) having an ethylenically unsaturated monomer (B), a polyvinyl alcohol resin (A), and water. At least one selected from the polyvinyl alcohol resin (A) and the polymer (X) has, in a main chain thereof, a structural unit derived from a monomer (C) represented by the following formula (I), (II), (III), or (IV). (The definitions of the symbols in the formulae are omitted.)
