COATED FILM AND BACKSIDE PROTECTIVE SHEET FOR SOLAR BATTERY MODULE

摘要

PROBLEM TO BE SOLVED: To provide a coated film having excellent adhesiveness between a resin layer and a substrate film and excellent scratch resistance of the resin layer, and to provide a backside protective sheet for a solar battery module having light resistance and ultraviolet light resistance which can withstand use under severe outdoor environments over a long period of time.SOLUTION: There are provided: a coated film in which A layer and B layer composed of a resin obtained by crosslinking a polyol with a polyisocyanate are laminated in the order of a substrate film/A layer/B layer on at least one surface of the substrate film, where the equivalence ratio (NCO/OH) of the isocyanate group (NCO) to the hydroxyl group (OH) of a polyol in the B resin is larger than that in the A resin.SELECTED DRAWING: None
