Problems solved by technology

[0004] However, as a result of the inventor's research, since the adhesive layer in the laminate described in the above-mentioned Japanese Patent Laid-Open No. 64-14235 has a strong adhesive force, the laminate does not adhere to the adhesive layer. It is difficult to easily peel off and recycle the adherend

Abstract

The present invention provides: an adhesive resin composition containing the following components (A), (B) and (C), wherein, (A): an olefin resin containing an epoxy group, (B): a curing agent, (C): thermally decomposable foaming agent; an adhesive film formed by forming the adhesive resin composition into a film; an adhesive laminated film formed by laminating the adhesive film on a support substrate; A laminate formed by bonding an adherend to an adhesive layer obtained by heating the adhesive film; and a method of heating the laminate and peeling and recovering the adherend from the laminate .

Description

technical field [0001] The present invention relates to an adhesive resin composition comprising an epoxy group-containing olefin resin, a curing agent, and a thermally decomposable foaming agent, an adhesive film formed by forming the adhesive resin composition into a film, and an adhesive film formed on a support base. An adhesive laminate film formed by laminating the adhesive film on a material, a laminate formed by bonding an adherend to an adhesive layer obtained by heating the adhesive film, and heating the laminate A method of peeling the laminate from the laminate and recovering the adherend. Background technique [0002] Laminates obtained by bonding adherends via an adhesive layer of an adhesive film are widely used in automotive parts, home appliances, electronic products, office supplies, daily necessities, and the like. Also disclosed in Japanese Patent Laid-Open No. 64-14235 is that a laminate that is strongly bonded to an adherend is obtained through an adhe...
