PROBLEM TO BE SOLVED: To provide a laminated polyester film having excellent adhesive properties with various coating layers and blocking resistance. SOLUTION: The laminated polyester film comprises a laminated film containing an acrylic resin in two types of polyester resins having different glass transition points and formed on at least one side surface of a polyester film. In this film, the two types of the polyester films include a polyester resin (A) having the glass transition point of 60 to 100°C, and a polyester resin (B) having the glass transition point of 0 to lower than 60°C. The polyester resin (B) contains 65 to 95 mol% of an isophthalic acid as an acid component, or 50 to 95 mol% of a diethylene glycol as a diol component. COPYRIGHT: (C)2003,JPO
