ABSTRACT:
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 (TgT(° C.)) of the acrylic resin in the emulsion.
