(57) [Summary] [Purpose] A film having various properties such as excellent mechanical strength, water resistance, solvent resistance, heat resistance, durability, and adhesion to a substrate, etc., even when cured at room temperature for a short time. To form. [Structure] A water-soluble, water-dilutable or water-dispersible polymer (A) is contained as a main component, and at least a part of the polymer (A) has a functional group capable of reacting with a 2-oxazoline group. An aqueous resin composition which is a polymer (A1) and contains a water-soluble polymer (B) having a 2-oxazoline group as a crosslinking agent for the polymer (A1) is used. |
