  An object of the present invention is to provide an aqueous resin composition and its uses, wherein the aqueous resin composition combines the blocking resistance and the frost damage resistance and thereby can secure the durability over a long period of time even under circumstances where a severe temperature cycle is present. As a means of achieving this object, the aqueous resin composition according to the present invention is an aqueous resin composition comprising an acrylic resin emulsion and a crosslinking agent as essential components, with the aqueous resin composition being characterized in that, when a coating film is formed from the aqueous resin composition, the formed coating film exhibits an elongation ratio (E (%)) that satisfies a specific relational expression along with the glass transition temperature (Tg T (° C.)) of the acrylic resin in the emulsion.

  本发明的目的是提供一种水性树脂组合物及其用途，其中该水性树脂组合物兼具抗阻塞性和抗霜冻破坏性，因此即使在存在严重温度循环的情况下也能确保长期的耐久性。作为实现该目标的一种方法，根据本发明的水性树脂组合物是一种水性树脂组合物，它由丙烯酸树脂乳液和交联剂作为基本成分组成，该水性树脂组合物的特征在于，当用该水性树脂组合物形成涂膜时，所形成的涂膜的伸长率（E (%)）与玻璃化转变温度（Tg T (摄氏度）。
