PROBLEM TO BE SOLVED: To provide an adhesive for a laminated sheet having excellent initial adhesiveness to a film and excellent long-term hydrolysis resistance at a high temperature, a laminated sheet produced by using the adhesive, and an outdoor material produced by using the laminated sheet.SOLUTION: There is provided an adhesive for a laminated sheet comprising a urethane resin obtained by mixing an acryl polyol with an isocyanate compound, and a silane compound, wherein the acryl polyol is produced by polymerizing a polymerizable monomer, the polymerizable monomer includes a hydroxyl-containing monomer and other monomer, and the other monomer includes acrylonitrile. The adhesive is excellent in initial adhesiveness to a film and long-term hydrolysis resistance at high temperature. The adhesive for laminated sheet is suitable for use in outdoor materials, and especially useful as an adhesive for solar cell back sheets. |
