Abstract
Present invention is a resin composition obtained by reacting polyolefin (A) with a (co)polymer (B) prepared from a copolymerizable monomer mixture (C) comprising an &agr;,&bgr;-monoethylenically unsaturated monomer and other copolymerizable monomers in a weight ratio (A)/(B)=1/9-9/1 under radical generation in an organic solvent, or by polymerizing a copolymerizable monomer mixture (C) comprising an &agr;,&bgr;-monoethylenically unsaturated monomer and other copolymerizable monomers in the presence of polyolefin (A) in a weight ratio (A)/(C)=1/9-9/1 in an organic solvent and successively by reacting the obtained reaction mass under radical generation; and the resin composition has good solution stability, does not cause liquid phase separation or solid precipitation, can be used as intact, is excellent in sprayability at high concentration, and, specifically, has novel function and effect that adhesion to polyolefin molded articles is excellent; and the resin composition can be favorably used for coating and primer because a coated film obtained by using a curing agent capable of reacting with an active hydrogen atom and/or hydroxyl group of the resin composition has excellent weatherability.
