PROBLEM TO BE SOLVED: To provide a polarizer protective polyester film excellent in adhesiveness to a polarizer and a functional layer such as a hard coat layer.SOLUTION: The polarizer protective polyester film includes an easily adhesive layer P1 on one surface of a polyester film and an easily adhesive layer P2 on the other surface. The easily adhesive layer P1 comprises a polyester resin (A), a polyvinyl alcohol resin (B) and a crosslinking agent (C), wherein 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 comprises, as main components, a urethane resin (D) having an aliphatic polycarbonate polyol as a constituent component, and a crosslinking agent (E). |
