WIPO Patent Application WO/2022/065286
Kind Code:
A1
Abstract:
Provided is an adhesive composition that provides high adhesion durability even in a high-humidity atmosphere or in water. An adhesive composition according to the present invention is characterized by: containing an acid-modified polyolefin (A) obtained by graft-modifying 100 parts by mass of a polyolefin (a1) with 0.2-5 parts by mass of an acid compound (a2); and having a storage elastic modulus of 130-330 MPa at 23ºC, as measured using a rheometer, and a yield elastic modulus of 30-120 MPa at 23ºC in a tensile test.
