Abstract
A novel chlorine-free modified polyolefin resin composition with excellent adherence to nonpolar substrates, excellent solubility in solvents, excellent compatibility with other resins, and without tack after painting and drying is obtainable by graft modifying a mixed resin having 40 to 99 parts by weight of polyolefin resin (A) and 1 to 60 parts by weight of ethylenic compound-unsaturated carboxylic acid copolymer (B) that contains 0.1 to 50% by weight of unsaturated carboxylic acid derivative, with unsaturated carboxylic acid derivative and/or its anhydride (C), the modified polyolefin resin composition having weight average molecular weight of 20,000 to 150 000 and the grafting weight of (C) being 0.1 to 20% by weight.
