(57) [Summary] [PROBLEMS] To harden in a relatively short time even at room temperature without generating harmful components such as formaldehyde, Provided is an aqueous acrylic resin composition which is excellent in flexibility and forms a film excellent in water resistance, solvent resistance, heat resistance, durability, adhesion to a substrate, and the like. A water-dispersible acrylic copolymer obtained by copolymerizing a functional group other than an oxazoline group, which has reactivity with an oxazoline-reactive group, is used as an acrylic containing an oxazoline-reactive group. An aqueous acrylic resin composition containing specific amounts of a water-soluble or water-dispersible polymer compound other than the copolymer and a water-soluble polymer compound containing an oxazoline group. |
