BIAXIALLY ORIENTED POLYESTER FILM FOR METAL SHEET LAMINATING MOLDING

摘要

A biaxially oriented polyester film to be laminated on a metal plate and molded, which comprises an aromatic polyester composition comprising: (A) an aromatic polyester which comprises ethylene terephthalate as the main recurring unit and a titanium compound and a phosphorus compound both of which satisfy at least one of the following expressions (1) and (2): 0.1 5 wherein Ti is the amount (mmol%) of elemental titanium of the titanium compound contained in this aromatic polyester and P is the amount (mmol%) of elemental phosphorus of the phosphorus compound contained in the aromatic polyester, and the following expression (3): 2 wherein Ti is as defined hereinabove, and which contains alkali metal compounds, germanium compound and antimony compound in a total amount of not more than 3 ppm in terms of the total of elemental alkali metals, elemental germanium and elemental antimony; and (B) 0.05 to 5.0 wt% based on the aromatic polyester composition of inert fine particles having an average particle diameter of 2.5 mu m or less.
