PROBLEM TO BE SOLVED: To provide a back sheet for solar cell module having excellent durability and weatherability and exhibiting high gas barrier properties and moisture barrier properties, by forming an adhesive layer of a novel resin, and to provide a back sheet of environment-friendly product, by utilizing a resin using a lot of carbon dioxide as its raw material.SOLUTION: In a back sheet for solar cell module that is one member for composing a solar cell module by laminating a plurality of kinds of film with an adhesive layer interposed therebetween, at least any one of the adhesive layer is a cured coating layer formed of a polyhydroxy polyurethane resin obtained by causing reaction of carbon dioxide as a part of raw material. The polyhydroxy polyurethane resin is induced from reaction of a compound having three or more 5-membered cyclic carbonate group in a molecule, and an amine compound. |
