ABSTRACT:
There is provided an aqueous resin composition which does not cause coagulation, can be cured at low temperature, and, by this curing, forms a coating superior in mechanical strength, water resistance, solvent resistance and adhesion to various substrates. The aqueous resin composition of this invention comprises an oxazoline group-containing polymer (A), a carboxyl group-containing polymer (B), and an acidic compound-amine salt catalyst (C). The curing is carried out by a reaction between the oxazoline group-containing polymer (A) and the carboxyl group-containing polymer (B) in the presence of the acidic compound-amine salt catalyst (C).
