    • A laminated base film for a photographic film, (A) which is a laminated film comprising a first layer formed substantially of polyethylene-2,6-naphthalenedicarboxylate and a second layer formed substantially of a polymer composition containing a 2,6-naphthalenedicarboxylate unit ##STR1## and an ethylene unit (--CH.sub.2 CH.sub.2 --) in a total amount of at least 50% by weight, and (B) which has a haze value of 3.0% or less, (C) in which the first layer has a plane orientation coefficient (NS.sub.1) of 0.270 or less, and (D) in which the first layer thickness/second layer thickness ratio is in the range of from 3/7 to 7/3 wherein the laminated film has a curl degree f.sub.2 in the longitudinal direction of 0 to 70%. This base film is provided with a proper curling which can be cured by the contraction of a photosensitive emulsion and has various suitable properties as a base film for a photographic film, such as transparency, lubricity, and the like.

    • A base film for a thermal transfer ribbon which is a biaxially oriented polyester film comprising polyethylene-2,6-naphthalene dicarboxylate as a main constitutional element, wherein in a temperature-dimensional change curve under load in a longitudinal direction of the film, the dimensional change from the original length of the film at temperatures of up to 200° C. is 1.0% or less and the dimensional change from the original length of the film at temperatures of up to 230° C. is 3.0% or less. This film may have a coating layer of at least one water-soluble or water-dispersible resin selected from the group consisting of an urethane resin, polyester resin, acrylic resin and vinyl resin-modified polyester resin, on one side thereof. The base film gives a thermal transfer ribbon which has excellent adhesion to a sublimation-type ink layer and excellent printing performance without blurred ink at the time of high-speed printing and without wrinkles formed by friction with a head.
    • 一种热转印带的基膜,其是包含聚2,6-萘二甲酸二乙酯作为主要构成元素的双轴取向聚酯膜,其中在膜的纵向负载下的温度 - 尺寸变化曲线中,尺寸 在最高达200℃的温度下从薄膜的原始长度的变化为1.0%以下,并且在高达230℃的温度下从薄膜的原始长度的尺寸变化为3.0%以下。 该膜可以在其一面上具有至少一种选自聚氨酯树脂,聚酯树脂,丙烯酸树脂和乙烯基树脂改性聚酯树脂的水溶性或水分散性树脂的涂层。 基膜给出了一种热转印带,其在高速印刷时具有优良的与升华型油墨层的粘附性和优异的印刷性能,而没有油墨模糊,并且没有由头部摩擦形成褶皱。
