    • A motion picture intermediate film has on one side of a support material, in order, an antihalation undercoat and at least one silver halide emulsion layer; and on the opposite side of the support a transparent, process surviving antistatic backing layer. The transparent, antistatic backing layer retains its antistatic properties after photographic film processing so that the motion picture intermediate film is protected from the generation of static charge during high speed printing of, for example, motion picture print films. The antistatic backing layer of the invention has a resistivity of less than about 1×1011 &OHgr;/□ after film processing. In a most preferred embodiment, the motion picture intermediate film of the invention is used to print images onto a motion picture print film that has a transparent antistatic backing layer. In accordance with the invention, use of a motion picture intermediate film as described above in making multiple prints onto motion picture print film results in surprisingly decreased levels of dirt and other image defects in the projected motion picture print film images, especially where such intermediate film is used to print onto print films having a process surviving antistatic backing layer.
    • 电影中间膜在支撑材料的一侧上依次是防晕晕底涂层和至少一个卤化银乳剂层; 并且在支撑体的相对侧上是透明的工艺存活的抗静电背衬层。 透明的抗静电背衬层在照相胶片处理之后保持其抗静电性能,使得电影中间膜在例如电影印刷胶片的高速印刷过程中免受静电荷的产生。 本发明的抗静电背衬层在膜加工后具有小于约1×10 11欧姆/平方的电阻率。 在最优选的实施例中,本发明的运动图像中间膜用于将图像打印到具有透明抗静电背衬层的电影印刷胶片上。 根据本发明,如上所述使用电影中间膜在动画图像打印胶片上进行多次打印导致惊人地降低了投影电影打印胶片图像中的污垢和其他图像缺陷的水平,特别是在这种中间膜 用于印刷具有工艺存活抗静电背衬层的印刷膜。

    • The present invention is a photographic element including a support with a polyolefin resin layer, which is preferably polypropylene, on each surface of the support. The photographic element includes a print or backmark retaining and spliceable antistatic layer having a dry coverage of from 10 mg/m2 to 10,000 mg/m2 on one of the free surfaces of the polyolefin layers. An imaging layer may be superimposed on the other free surface of the polyolefin layers. The antistatic layer includes a (i) conductive agent, preferably a combination of an alkali metal salt and a polymerized alkylene oxide, (ii) colloidal silica, preferably aluminum modified colloidal silica and (iii) a polymeric film-forming binder with a peel strength of 200 g or above on a polypropylene surface on which the antistatic layer of the present invention is to be formed. Such an antistatic layer is expected to provide surface electrical resistivity of less than 12 log &OHgr;/□, preferably equal to or less than 11 log &OHgr;/□, and excellent backmark retention characteristics and spliceability for commercial photofinishing equipment such as the Gretag CLAS 35 printers.
    • 本发明是一种照相元件,其包括在支撑体的每个表面上具有聚烯烃树脂层的支撑体,其优选为聚丙烯。 照相元件包括在聚烯烃层的一个自由表面上具有10mg / m 2至10,000mg / m 2的干覆盖率的印刷或背面保持和可拼接的抗静电层。 成像层可以叠加在聚烯烃层的另一自由表面上。 抗静电层包括(i)导电剂,优选碱金属盐和聚合的烯化氧的组合,(ii)胶体二氧化硅,优选铝改性的胶体二氧化硅和(iii)具有剥离强度的聚合物成膜粘合剂 在其上将形成本发明的抗静电层的聚丙烯表面上为200g以上。 预期这种抗静电层的表面电阻率小于12logΩ/平方,优选等于或小于11logΩ/平方,以及用于商业照相洗印加工设备如Gretag CLAS 35打印机的优异的背标保持特性和可拼接性 。
