    摘要: The present invention provides a polyester film which is excellent in hydrolysis resistance of a base film, is hardly deteriorated in adhesion property to various members or top-coating agents, and can suitably used, for example, as a film for a protective member for protecting a back surface of solar cells. The present invention relates to a biaxially oriented polyester film in the form of a laminated film comprising a biaxially oriented polyester base film having a phosphorus element content of 0 to 170 ppm and a terminal carboxylic acid content of not more than 26 equivalents/t, and a coating layer formed on at least one surface of the biaxially oriented polyester base film which comprises a polyurethane having a polycarbonate skeleton or a polyether skeleton and a crosslinking agent, wherein the laminated film has a haze value of not more than 10%.

    摘要: White, biaxially oriented polyester films which have a base layer B which comprises a thermoplastic polyester such as polyethylene terephthalate, and which comprise substantially only TiO2 as a white pigment, whose R value is less than 43 daN/mm2, whose emax ratio is less than 2.5 and at least one of whose two surfaces of the film has been provided with an acrylate-containing coating, are particularly tear-resistant and do not tend to delamination and are therefore suitable in particular as lid films for food containers, for example yoghurt cups. A process is described for producing the films.
