PROBLEM TO BE SOLVED: To provide a polarizer protective polyester film excellent in adhesiveness between a polarizer and a functional layer such as a hard coat layer.SOLUTION: A polarizer protective polyester film has an easily adhesive layer P1 on one surface of a polyester film and an easily adhesive layer P2 on the other surface thereof. The easily adhesive layer P1 contains a polyester resin (A), a polyvinyl alcohol resin (B) and a crosslinking agent (C). The polyester resin (A) has an acid value of 20 KOH mg/g or less and the polyvinyl alcohol resin (B) has a saponification degree of 60 to 85 mol%. The easily adhesive layer P2 contains, as main components, an urethane resin (D) having aliphatic polycarbonate diol as a constituent component, and a crosslinking agent (E). A number average molecular weight of the aliphatic polycarbonate diol is 1,500-4,000.SELECTED DRAWING: None |
