An object of the present invention is to provide an adhesive for laminated sheets, which is excellent in initial adhesion to a plastic film and is also excellent in long-term hydrolysis resistance at high temperature in the production of a laminate using the plastic film; 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, said adhesive comprising: a urethane resin obtainable by mixing an acrylic polyol with an isocyanate compound; and a silane compound, wherein the silane compound contains an epoxy based silane compound, and 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 is excellent in initial adhesion to a film and is also excellent in long-term hydrolysis resistance at high temperature. The adhesive for laminated sheets is preferably used for an outdoor material, and is particularly useful as an adhesive for solar battery back-sheets. |
