    摘要: The present invention is an imaged photographic element having a protective overcoat thereon. The protective overcoat is formed by providing a photographic element having at least one silver halide light-sensitive emulsion layer. A first coating of hydrophobic polymer particles having an average size of 0.01 to 1 microns, a melting temperature of from 55 to 200° C. at a weight percent of 30 to 95, and gelatin at a weight percent of 5 to 70 is applied to form a first layer over the silver halide light-sensitive emulsion layer. A second coating of abrasion resistant particles having an average size of from 0.01 to 1 microns is applied to form a second layer over the first layer. The photographic element is developed to provide an imaged photographic element. The first and second layers are fused to form a protective overcoat.

    摘要: The present invention is a photographic element which includes a support, and at least one light-sensitive silver halide layer on a front side of the support. The photographic element has on the backside of the support an antistatic layer; a transparent magnetic recording layer; and a lubricating overcoat layer. The lubricating overcoat layer is farthest from the support and includes a lubricant of the general formula:R--CONH.sub.2where R is a long chain hydrocarbon between 12 and 30 carbons, preferably between 16 and 22.The present invention also provides a method of producing an imaging support which includes, providing a support, and simultaneously coating on the support; a transparent magnetic recording layer including magnetic particles, a polymeric binder and an organic solvent, and a lubricating overcoat layer, the lubricating overcoat layer comprising a lubricant of the general formula:R--CONH.sub.2where R is a long chain hydrocarbon between 12 and 30 carbons, preferably between 16 and 22, and an organic solvent, and drying the magnetic recording layer and the lubricating overcoat layer.

    摘要: The invention provides a blend of metal oxide, such as silicon oxide, with etheric phosphazene. The invention optionally contains salt for antistatic coatings. The composition of the invention is formed by preparing solutions of etheric phosphazene and alkoxysilane, such as tetraethoxysilane. The solutions are then coated onto suitable substrates, or cast films and cured at room temperature or with moderate heating. The coatings and films produced are transparent, tough, hard, and flexible. They are multicomponent blends of the silicon oxide and phosphazene. It is also within the invention to form the blends with other metal oxides, rather than silicon, such as titanium, aluminum, or zirconium. The composite may be doped with low lattice energy salts to form antistatic composites.
