(57) [Problem] To provide a novel acid-modified polyolefin having excellent adhesion to a non-polar substrate and having no tack after coating and drying. SOLUTION: The content of the unsaturated carboxylic acid derivative and / or its anhydride (B) is 0.1% by weight or more and 30% by weight or less and the content of N-substituted maleimide (C) is based on polyolefin (A). A modified polyolefin resin composition having a weight-average molecular weight of 5,000 to 150,000, which has been graft-modified so that the amount is 0.001% to 40% by weight. |
