    摘要: The present invention provides: an ink jet recording material which displays sufficient water resistance and further, excellent definition of initial images; and a coating agent therefor to give such an ink jet recording material. A first coating agent for ink jet recording materials, according to the present invention, comprises: an aqueous polymer having a carboxyl group; and a water-soluble polymer having an oxazoline group as a crosslinking agent. A second coating agent for ink jet recording materials, according to the present invention, comprises a polymer and a crosslinking agent, wherein the polymer has both a structural unit, as formed by ring-opening polymerization of an oxazoline compound, and a carboxyl group. An ink jet recording material, according to the present invention, has on at least one face thereof a coated and cured layer of the above present invention first coating agent and/or a coated and cured layer of the above present invention second coating agent, and displays high water resistance and excellent image quality.

    摘要: 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).
