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.)
本发明提供了一种耐热性、耐水性、耐热水性、耐沸水性和粘度稳定性极佳,且抗污性极佳的水性乳液组合物。本发明涉及一种水性乳液组合物,包括水性乳液(D)和环酸酐(E)。水性乳液(D)包括具有乙烯不饱和单体(B)的聚合物(X)、聚乙烯醇树脂(A)和水。聚乙烯醇树脂 (A) 和聚合物 (X) 中至少有一种在其主链中具有由下式 (I)、(II)、(III) 或 (IV) 所代表的单体 (C) 衍生的结构单元。
