ABSTRACT:
The present invention is to provide a laminated polyester film with excellent adhesive properties for use in a laminating material, and the laminated polyester film is a film in which a resin layer including a polyester resin and a oxazoline-based cross-linking agent is laminated on at least one side surface of polyester film, diethylene glycol accounts for 40 mole % or more of all diol components constituting the polyester resin and the mass ratio of the polyester resin to the oxazoline-based cross-linking agent resin layer is within a range of 20/80 to 80/20. Furthermore, the present invention is to provide a flame-retardant polyester film in which a polyimide-including layer is laminated on both sides of the laminated polyester film and also a copper-clad laminated plate in which the flame-retardant polyester film is used, and also a circuit substrate in which the copper-clad laminated plate is used.
