Title: LAMINATE, MANUFACTURING METHOD FOR SAME, AND RESIN FILM WITH ADHESIVE LAYER
Abstract:
The present invention provides a laminate that is excellent in terms of dimensional stability of the adhesive layer during curing, and in terms of adhesive strength, thermal resistance, flexibility, electrical insulation, low dielectric constant, and low dielectric tangent of the adhesive layer after curing. This laminate is provided with: an electrically conductive pattern (3); a first layer (1) to be bonded, which exhibits an insulating property and on which the electrically conductive pattern (3) is supported; and a second layer (2) to be bonded, which is disposed facing the first layer (1) to be bonded with a cured adhesive layer (4) therebetween. The second layer (2) to be bonded is an electrically conductive layer or an insulating layer. The cured adhesive layer (4) is a cured product of a thermosetting adhesive agent that contains a polyisocyanate component and a styrene-based elastomer having a carboxylic acid anhydride group. The first layer (1) to be bonded and the insulating layer are each independently a resin film selected from the group consisting of a polyimide film, a liquid crystal polymer film, and an alicyclic polyolefin film having a glass transition temperature of 100-400°C.
