An object of the present invention is to provide an adhesive for laminated sheets, which is excellent in initial adhesion to a film and is also excellent in long-term hydrolysis resistance at high temperature; a laminated sheet obtainable by using the adhesive; and an outdoor material obtainable by using the laminated sheet. 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 acrylic polyol is obtainable by polymerizing a polymerizable monomer, the polymerizable monomer contains a monomer having a hydroxyl group and the other monomer, and the other monomer contains acrylonitrile. The adhesive for laminated sheets is excellent in initial adhesion to a film and is also excellent in long-term hydrolysis resistance at high temperature. The adhesive is preferably used for outdoor materials, and is particularly useful as an adhesive for solar battery back sheets. |
