PROBLEM TO BE SOLVED: To provide an adhesive which has excellent reworkability, prevents voids in optical laminates, inhibits flotation, peeling and foaming between glass substrates and adhesive layers, and has excellent durability. SOLUTION: This adhesive comprises an acrylic resin (1), an acrylic resin (2), a silicone oligomer (3), and a cross-linking agent (4). The acrylic resin (1): an acrylic resin comprising a (meth)acrylate of formula (A) and a monomer (B) and having a Mw of 1,000,000 to 2,000,000. The monomer (B): a monomer (B-1) and/or a monomer (B-2). The monomer (B-1): a monomer containing a carboxyl group and an olefinic double bond. The monomer (B-2): a monomer having an olefinic double bond and a polar functional group such as a hydroxyl group, amido group, amino group, epoxy group, oxetanyl group, aldehyde group or isocyanato group. The acrylic resin (2): an acrylic resin comprising the monomer (A) and the monomer (B) and having a Mw of 50,000 to 500,000. The silicone oligomer (3): an oligomer comprising 2 to 100 compounds represented by formula S (R3and R4are each an alkyl or the like; X and Y are H, alkyl or the like). COPYRIGHT: (C)2007,JPO&INPIT
