    Abstract: The present invention is a flame-retardant polyester film including resin layers laminated on both surfaces of a polyester film, wherein the resin layer satisfies 15 ‰¤ (Wc 1 - Wc 2 )/Wc 0 × 100 ‰¤ 99 (where Wc 0 represents the weight of the resin layer, Wc 1 represents the weight of the resin layer after the temperature thereof is raised from 25°C to 600°C in air, and Wc 2 represents the weight of the resin layer after the temperature thereof is raised from 25°C to 800°C in air), and has a non-flammable'gas generating rate of 3 to 40 percent over the range of 180°C to 450°C. The present invention provides a flame-retardant polyester film having an excellent flame retardancy, and adhesive tapes, flexible printed circuits, a membrane switch, a film heater, and a flat cable, each including the flame-retardant polyester film.

    Abstract: A laminated film for thermosensitive image transfer material, comprises a biaxially oriented polyester film including at least one surface thereof a laminated layer containing 50% by weight or more of a wax-based compound, wherein the laminated layer has island-like protrusions, wherein the island-like protrusions have stripe-like protrusions on their surfaces, and wherein a density of the island-like protrusions is 2 to 100 protrusions/100 mu m . Such laminated film for thermosensitive image transfer material has excellent hot sticking resistance even in a high energy-applied range, slidability, and printability that cannot be achieved conventionally.

    Abstract: A polyester film comprises a polyester whose dicarboxylic acid copolymerized component contains (i) an aromatic dicarboxylic acid having a metal sulfonate and/or a derivative thereof and (ii) a polyetherdicarboxylic acid represented by the following chemical formula (a) and having a mean molecular weight in the range of 600 to 20,000 and/or a derivative thereof. R OOCCH2-(O-R )n -OCH2 COOR (a) where, "R " and "R " are hydrogen or C1 - 8 alkyl groups, "R " is a C2-8 alkylene group and "n" is a positive integer. The polyester film can be used as a base film for a photosensitive material.

    Abstract: A film for thermal porous printing paper and a thermal porous printing paper composed of the film and a porous support are disclosed. The film comprises a biaxially oriented polyester film having a crystal melting energy, Delta Hu, of 3 to 11 cal/g and showing a difference between the crystal melting completion temperature and crystal melting initiation temperature, delta Tm, of 50 to 100 deg.C. Hence it has such a high heat sensitivity that characters and solid images are distinctly recorded with substantially no unevenness in thickness or density of the images. In addition, since it eliminates the necessity of reducing the thickness of the film.
