    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： A photographic element which includes a support having a frontside and a backside, at least one silver halide emulsion layer superposed on the frontside of the support; and a protective overcoat layer superposed on the backside of the support. The protective overcoat layer is formed from a coating solution comprising a continuous liquid organic medium having therein a mixture of dispersed core/shell polymer particles and a soluble polymer. The core/shell polymer particles comprise a core portion, which is insoluble in the organic medium, and a shell portion which has an affinity for both the core portion and the organic medium and has an acid number of from 25 to 200. The soluble polymer has an acid number of from 70 to 500 and the acid number of the soluble polymer is greater than the acid number of the shell of the core/shell polymer particles.

    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.
