SINGLE-LAYER, ORIENTED THERMOPLASTIC POLYESTER FILM CAPABLE OF STRUCTURING BY MEANS OF ELECTROMAGNETIC RADIATION, FOR PRODUCING SELECTIVELY METALLIZED FILMS

摘要

Provided are a monolayered oriented polyester film which is prepared with a low cost and has an excellent alignment and high tensile strength, elastic modulus, elongation at break and tensile stress to lateral and longitudinal axes, its preparation method, its use in a printed circuit board, a ribbon cable, a smart card, a RFID label, a membrane keyboard and a film substrate, and a use of a metal compound used in the film. The monolayered oriented polyester film contains 0.1-15.0 wt% of a metal compound which isolates a metal of basic shape in polyester by the irradiation of an electromagnetic wave, wherein the film has a total thickness of 5-500 micrometers and is oriented to at least one axis. Preferably the metal compound is a metal oxide or spinel, and the metal oxide is CuCr2O4. Preferably the polyester film has a silicone coating on at least one surface.
