    摘要: Disclosed is an adhesive for laminated sheets comprising: a urethane resin obtainable by mixing an acrylic polyol with an isocyanate compound; and a silane compound; wherein the silane compound contains a glycidyl based silane compound, wherein the acrylic polyol is obtainable by polymerizing polymerizable monomer, the polymerizable monomer contains a monomer having a hydroxyl group and the other monomer, and the other monomer contains acrylonitrile, and the isocyanate compound contains at least one selected from xylylene diisocyanate and hexamethylene diisocyanate. The adhesive for laminated sheets has a moderate curing rate and is excellent in initial adhesion to a film and in long-term hydrolysis resistance at high temperature; it is also excellent in weatherability.
