    • The present invention is a photographic element including a substrate with a polyolefin resin layer, which is preferably polypropylene, on each surface of the said substrate. The photographic paper includes a print or backmark retaining and spliceable antistatic layer having a dry coverage of from 10 mg/m.sup.2 to 10,000 mg/m.sup.2 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) a positively charged colloidal oxide sol and (iii) a film forming binder which is an interpolymer of a primary amine addition salt with a peel strength of 200 g or above on the polyolefin surface on which the antistatic layer of the present invention is to be formed. The antistatic layer is expected to provide surface electrical resistivity of less than 12 log .OMEGA./, preferably equal to or less than 11 log .OMEGA./, and excellent backmark retention characteristics and spliceability for commercial photofinishing equipment such as the Gretag CLAS 35 printers.
    • 本发明是在所述基板的每个表面上包括具有聚烯烃树脂层的基材(其优选为聚丙烯)的照相元件。 照相纸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)带正电荷的胶体氧化物溶胶和(iii)作为伯胺的互聚物的成膜粘合剂 在其上将形成本发明的抗静电层的聚烯烃表面上具有剥离强度为200g以上的加成盐。 预计抗静电层的表面电阻率小于12log OMEGA / + Z,优选等于或小于11log OMEGA / + Z,以及商业照相洗印加工设备(如Gretag CLAS 35)的优异的背标保持特性和可拼接性 打印机
