| 摘要 |
A resin composition of the present invention is obtainable by adding a photo-polymerization initiator (d) to a resin solution (a) containing a modified product of a thermoplastic resin (A). The modified product is prepared by conducting radical polymerization of the thermoplastic resin (A) with a (co)polymer (B) of a copolymerizable monomer (C) comprising a monomer having an alpha , beta -mono-ethylenically unsaturated group, or the monomer and other copolymerizable monomers in a weight ratio (A)/(B) of 1/9 to 9/1, in an organic solvent, or by conducting polymerization of a copolymerizable monomer (C) comprising a monomer having an alpha , beta -mono-ethylenically unsaturated group, or the monomer and other copolymerizable monomers in a weight ratio (A)/(C) of 1/9 to 9/1, in an organic solvent in the presence of the thermoplastic resin (A), and then conducting radical polymerization thereof. <??>The above resin composition has excellent adhesion to polyolefin resin-molded products such that is an effect unobtainable heretofore. <??>A paint of the invention comprises the resin composition of the present invention or a main component of the resin composition and a curing agent capable of reacting with active hydrogen and/or hydroxyl group. The paint is suitable for uses such as primers, and paints and adhesives for polyolefin resin-molded products. <??>A process for forming a coating film according to the invention comprises the step of applying the resin composition or the paint and irradiating with light.
