Zusammenfassung:	PROBLEM TO BE SOLVED: To establish an excellent antistatic performance using a conductive polymer, enhance the resistance against solvent and the coating film performance by enhancing the tape exfoliating force using acrylic resin and also adjusting the bridging density through the use of an appropriate bridging agent, and enhance the anti-contamination function by adding fluoro-resin. SOLUTION: Manufacturing method according to the invention for a polyester film comprises a stage to make uniaxial elongation of a polyester base film, a stage to fabricate an antistatic coating liquid containing a conductive highpolymer resin, acrylic resin, the bridging agent and fluoro-resin, a stage to form an antistatic layer by applying the coating liquid to one or both surfaces of the polyester film subjected to uniaxial elongation, and a stage to make biaxial elongation of the polyester base film furnished with the antistatic layer as described. This is free of separation or dissolution of an antistatic agent from the antistatic layer when washing is made with water or alcohol. Also it is possible to establish an excellent anti-contamination function and enhance the tight attaching force with a sticky tape. COPYRIGHT: (C)2009,JPO&INPIT
