    • A molded article for photographic photosensitive material formed of a molding resin composition consisting essentially of 100 parts by weight of crystalline resin composition comprising crystalline resin and at least lubricant or antistatic agent, 0.001 to 2 parts by weight of antioxidant and 5 to 90 parts by weight of acrylic acid copolymer resin, and a molded article for photographic photosensitive materials formed of a light-shielding thermoplastic resin composition comprising a light-shielding material of which the surface has been treated with a surface-treating material and antioxidant. The molded article can inhibit bleeding out and thermal decomposition of antistatic agent, lubridant and organic nucleating agent, and can prevent various troubles induced therefrom.
    • 一种用于照相感光材料的模制品,其由模制树脂组合物形成,该模塑树脂组合物基本上由100重量份的包含结晶树脂和至少润滑剂或抗静电剂的结晶树脂组合物,0.001至2重量份抗氧化剂和5至90重量份 的丙烯酸共聚物树脂,以及由遮光性热塑性树脂组合物形成的感光感光材料的成型体,其包含表面已经用表面处理材料和抗氧化剂处理的遮光材料。 模制品可以抑制抗静电剂,杂化剂和有机成核剂的渗出和热分解,并且可以防止由其引起的各种麻烦。

    • A substrate of a photosensitive web material of which the base end portion is gradually thinned toward the base end a core for a rolled photographic film which comprises a core body and a crosslinked foamed sheet having an expansion ratio of 18 to 45 times and a thickness of 0.2 to 2.0 mm which contains more than 50 wt. % in the sum of one or more members selected from the group consisting of polyethylene resin having a density of less than 0.930 g/cm.sup.3, ethylenevinyl acetate copolymer resin having a comonomer content of less than 25 wt. % and ethylene-ethyl arcylate copolymer resin having a comonomer content of less than 25 wt. % is disposed on the surface of the core body. The substrate and core sharply reduce the occurrence of marking troubles and pressure mark troubles on the photosensitive web material near the core caused by the difference in levels induced by the base end portion of the web.
    • 感光纤维网材料的基材,其基端部朝向底端逐渐变薄,用于卷筒纸照相胶片的芯,其包含芯体和发泡比为18〜45倍的交联发泡片材,其厚度为 0.2至2.0mm,其含有大于50wt。 选自密度小于0.930g / cm 3的聚乙烯树脂的一种或多种成分的总和中的%,共聚单体含量小于25wt。的乙烯 - 乙酸乙烯酯共聚物树脂。 %和乙烯 - 乙酸乙酯共聚物树脂,其共聚单体含量小于25wt。 %设置在芯体的表面上。 基板和芯线由于由网片的基端部分引起的电平差异,大大降低了芯体附近的感光纤维网材料上的标记问题和压力标记问题的发生。
