Abstract
Novel photographic processing compositions including a polymeric oxime viscosity-increasing reagent for processing an exposed film unit to provide a photographic image. While this photographic image may be in black-and-white or in color and prepared by any of the heretofore known systems, of particular interest are color diffusion transfer systems for preparing a color image viewable without separation of any of the components or layers of the photographic product. The invention also includes a novel class of polymeric oximes which may be employed in such compositions.
