  • Patent number: 5756272
    Abstract: 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.
