Abstract
The present invention has an object to provide a modified polyolefin resin capable of forming a coating film that is excellent in water-resistant adhesiveness under a high temperature condition. The present invention provides a modified polyolefin resin including a graft-modified product in which a component (A) that is a polyolefin resin is graft-modified with a component (B) that is an α,β-unsaturated carboxylic acid or a derivative thereof, and having a tensile modulus of 250 MPa or higher, and a weight-average molecular weight of 70,000 or more and less than 200,000.
