POLYESTER FILM, AND SOLAR-CELL BACK SHEET AND SOLAR-CELL USING THE SAME
摘要：
A polyester film has a laminate structure including a polyester layer (layer P1) containing a crystalline polyester and inorganic particles and a polyester layer (layer P2) containing a crystalline polyester, inorganic particles, and an antihydrolysis segment, wherein the content (Wa2) of the inorganic particles in the layer P2 is at least 10 mass % of the layer P2, the difference between the content (Wa2) (mass %) of the inorganic particles in the layer P2 and the content (Wa1) (mass %) of the inorganic particles in the layer P1, Wa2−Wa1, is 5 to 25 mass %, and the content (Wb2) of the antihydrolysis segment in the layer P2 is 0.02 to 1.5 mass % of the layer P2.
