    摘要: The present invention is a photographic element having a support, at least one silver halide emulsion layer superposed on a first side of the support and a protective overcoat superposed on a second said of the support. The protective overcoat includes a polyurethane having a tensile elongation to break of at least 50% and a Young's modulus measured at 2% elongation of at least 50,000 lb/in.sup.2, an interpolymer composed of repeating units of A and B wherein A comprises a fluorine containing acrylate or a fluorine containing methacrylate monomer and B comprises an ethylenically unsaturated monomer containing hydratable groups and an electrically conductive agent.

    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.

    摘要: The present invention is an imaging base which includes a polyester film support and an adhesion promoting layer directly adhered to a surface of the support. The adhesion promoting layer is formed by the coating and subsequent drying of a coating composition comprising a gelatin-grafted-polyurethane. The gelatin-grafted polyurethane is covalently bound to the polyurethane through a grafting agent wherein the ratio of gelatin to polyurethane is from 1:10 to 2:1. In one embodiment of the invention the imaging support is coated with at least one silver halide emulsion layer to form a photographic element.
