<p><P>PROBLEM TO BE SOLVED: To provide a solar cell module back protective sheet superior in scratch resistance, humidity/heat resistance, weatherability and heat resistance. <P>SOLUTION: In the solar cell module back protective sheet, at least a protection layer 11, a primer layer 12, a polyester based resin layer 14, 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 protection layer 11 is formed by crosslinking and curing an ionizing radiation curing resin composition by ionizing radiation irradiation. The primer layer 12 is obtained by adding pigment to be dispersed in polyurethane resin formed by crosslinking and curing a diol component where 0 to 30 pts.wt. of acrylic diol having hydroxyl groups in both ends is blended with respect to 100 pts.wt. of diol formed of polycarbonate diol and polyester diol, and urethane based prepolymer by isocyanate cross-linking agent. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
