<p><P>PROBLEM TO BE SOLVED: To provide a back protective sheet for solar cell module, which is superior in adhesion, heat resistance, weatherability and durability. <P>SOLUTION: In the back protective sheet 1 for solar cell module, at least a protection layer 11, a primer layer 12, a polyester-based resin layer 13 and a substrate formed of thermoplastic resin are laminated in this order from an external side of a backside of the solar cell module. The surface protection layer 11 is formed by crosslinking and curing an ionizing radiation curing resin composition by ionizing radiation irradiation. The primer layer 12 is formed of polyurethane resin (P) formed by crosslinking and curing urethane-based prepolymer (Ppre) including urethane prepolymer (PpreH) or a diol component (OL) and urethane prepolymer (PpreC) by isocyanate-based crosslinking agent. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
