A graft copolymer produced by polymerizing an ethylenically unsaturated monomer in the presence of a fluorine-containing resin having reactive double bonds via a urethane linkage is excellent in transparency and pigment dispersibility and can provide a coating composition excellent in weather resistance.

Process for producing graft copolymer

A resin composition for coating comprising (A) a polyester-modified vinyl copolymer obtained by copolymerization of (a) a polyester resin having 5 to 60% by weight of oil or fatty acid component with special physical limitations, (b) a polymerizable unsaturated monomer having at least one tertiary amino group, (c) a polymerizable unsaturated monomer having at least one carboxyl group, and (d) an unsaturated monomer copolymerizable with the components (b) or (c), and (B) an epoxy resin can be cured at room temperature or with slight heating to give a coating film excellent in dispersibility of pigment having large oil absorption.

Coating resin composition

A coating resin composition comprising a chlorinated polyolefin-containing polymer obtained by polymerizing a monomer blend containing 0.01 to 5% by weight of an unsaturated organic silane compound in the presence of a chlorinated polyolefin resin having a chlorine content of 50% by weight or less can yield molded articles or coatings excellent in adhesiveness, gloss, resistance to gasoline, resistance to alcohol, or the like.
