    摘要： A coating composition comprising a solution of an electrically-conductive polymer and an organic solvent media wherein the solvents are selected from the group consisting of alcohols, ketones, cycloalkanes, arenes, esters, glycol ethers and their mixtures; the media having a water content of less than 12 weight percent. Such a coating composition provides a means to protect an imaging element against the accumulation of static electrical charges before and after image processing while also providing the element with improved manufacturability and physical properties.

    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.

    摘要： The present invention is a motion picture film including a support having on one side thereof an antihalation undercoat and at least one silver halide emulsion layer. The motion picture film has on the opposite side thereof an antistatic layer and a protective overcoat. The protective overcoat includes a layer of a polyurethane binder having a tensile elongation to break of at least 50% and a Young's modulus measured at a 2% elongation of at least 50000 lb/in.sup.2, and a topcoat farthest from said support. The topcoat is an interpolymer having repeating units of A and B wherein A is a fluorine containing acrylate or methacrylate monomer and B is an ethylenically unsaturated monomer containing hydratable groups.
