摘要： 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.
