Polyester photographic film support

摘要

The present invention is a photographic film base including a polyester support. Superposed on the polyester support is a polymer layer superposed having a photoreactive moiety and a gelatin reactive moiety. A gelatin subbing layer is attached to the polymer layer. The present invention includes a photographic element having at least one light sensitive silver halide emulsion layer on the described photograpic film base. The present invention also includes a process for producing a film base which includes providing a polyester support, exposing the polyester support to an energy treatment, applying a polymer coating to the polyester support, the polymer coating having a photoreactive moiety and a gelatin reactive moiety, and applying a gelatin subbing layer to the polymer coating.
