Abstract: A biaxially oriented polyester film wherein the ratio (=IMD /IND) of the peak intensity (IMD) in the longitudinal direction to the peak intensity (IND) in the thickness direction determined at 1615 cm by laser Raman scattering method is not less than 6; and a process for production of a biaxially oriented polyester film which comprises the steps of controlling the ratio (A/B) of the maximum thickness (A) of the edge portion of a cast film to the thickness (B) of the central portion in the transverse direction thereof in the range of 2 to 6, biaxially stretching the cast film, and controlling the peak intensity ratio of the biaxially oriented film determined by the laser Raman scattering method in the above-described range. The biaxially oriented polyester film thus produced has a specific orientation in the longitudinal direction, and therefore has great strength in the longitudinal direction and small irregularity in properties such as thickness or birefringence.

Abstract: A polyester composition containing a ligand which is able to coordinate to a metal or a metal ion and contains as the donor atom at least one of nitrogen, sulfur, and oxygen. In this composition, the metal catalyst causative of lowering the heat resistance of the polyester can be inactivated by the ligand. The polyester composition and films made thereof are excellent in heat resistance, colorability, and weather resistance. A polyester composition improved in heat resistance can be produced by adding, in the step of producing a polyester with a metal catalyst, a ligand which is able to coordinate to a metal or a metal ion and contains as the donor atom at least one of nitrogen, sulfur, and oxygen to thereby separate and recover the catalyst.

Abstract: PROBLEM TO BE SOLVED: To provide a polyester film which can be easily laminated to a tinplate with a sufficient strength and also possesses an excellent flavor property. SOLUTION: A polyester film for laminating a tinplate is a laminated film consisting of a substrate layer made of a polyester A having a melting point of 246-270 deg.C and an adhesive layer made of a polyester B having a melting point of 200 deg.C-the melting point of the polyester A and arranged on at least one surface of the substrate layer. An practical heat treating temperature for the laminated film is the melting point of the polyester B-that of the polyester A.
