Abstract:
The present invention provides an adhesive for laminating a metal foil and a resin film, including: (A) 1% to 20% by mass of polyurethane which has at least one functional group selected from the group consisting of a hydroxy group, an acryloyl group, and a carboxy group; (B) 30% to 90% by mass of a monomer which does not has an active hydrogen and has two or more ethylenically unsaturated bonds; (C) 1% to 55% by mass of an aliphatic monomer which has one ethylenically unsaturated bond; (D) 1% to 15% by mass of a polyisocyanate compound; and (E) 0.5% to 5% by mass of a photoinitiator. The (B) has a cyclic structure, and the (C) has a linear hydrocarbon group, a branched hydrocarbon group, or a cycloalkyl group.
