    摘要： 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.
