ABSTRACT:
(1) A coating resin composition consisting essentially of a self-crosslinking resin (I) having at least one hydroxyl group and at least one blocked isocyanate group in the molecule wherein the resin (I) is prepared by reacting some of the free isocyanate groups of a vinyl polymer (A) having at least two free isocyanate groups in the molecule with some of the hydroxyl groups of a polyolefin resin (B) having at least two hydroxyl groups in the molecule, and subsequently reacting a blocking agent with the remaining free isocyanate groups, and (2) a coating resin composition consisting essentially of a self-crosslinking resin (II) having at least one hydroxyl group and at least one blocked isocyanate group in the molecule wherein the resin (II) is prepared by reacting all free isocyanate groups of a vinyl polymer (C) having at least one free isocyanate group and at least one blocked isocyanate group in the molecule with some of the hydroxyl groups of a polyolefin resin (B) having at least two hydroxyl groups in the molecule.
