    摘要: A biaxially oriented film to be laminated on a metal, which is a laminate film comprising (A) a first layer of a polyester comprising ethylene terephthalate as a main recurring unit; and (B) a second layer formed from a composition of a polycarbonate and polyesters, the polycarbonate and the polyesters being each contained in amounts of 20 to 50% by weight and 50 to 80% by weight based on the total thereof; the polyesters consisting essentially of a first polyester comprising ethylene terephthalate as a main recurring unit and having a terminal carboxyl group concentration of more than 5 eq./10.sup.6 g and a second polyester comprising butylene terephthalate as a main recurring unit and having a terminal carboxyl group concentration of less than 20 eq./10.sup.6 g; and the first and second polyesters being each contained in an amount of 10 to 90% by weight based on the total thereof; and in which (C) the plane orientation coefficients of the first layer and second layer are both in the range of 0.05 to 0.10.

    摘要: A photoresist layer supporting film is (A) formed from a polymer composition comprising (i) 55 to 100% by weight of a copolyester containing ethylene terephthalate units as a main recurring unit and having a melting point of 210 to 250.degree. C. and (ii) 0 to 45% by weight of polybutylene terephthalate or a copolyester containing butylene terephthalate units as a main recurring unit and having a melting point of not lower than 180.degree. C. and (B) has a plane orientation coefficient of 0.08 to 0.16. Since this supporting film is excellent in substrate shape follow-up properties and resolution, it is suitable for the preparation of a photoresist film laminate by laminating a protective film and a photoresist layer on the surface thereof.

    摘要: Provided is a polyester film containing a lubricant having an average particle diameter of 0.001 to 2.5 .mu.m in an amount of 0.01 to 5.0% by weight and suited for the lamination onto the surface that comes in contact with the contents of an easy-open can cap. The polyester film has a plane orientation coefficient of 0.115 to 0.140, two or more endothermic peaks in DSC curve in the range of 170 to 270.degree. C., a peak temperature of 60 to 120.degree. C. of a complex elastic modulus (E") in water and an intrinsic viscosity of 0.50 to 0.64 dl/g. Having these features, the polyester film laminated onto a metal sheet is excellent in can-capping processability and in corrosion resistance even after holding at high temperature.
