Polymeric hydroxamic acid polyvalent metal salt interlayer for photographic diffusion transfer products

摘要

Photosensitive elements for color diffusion transfer film units comprising a support layer, at least two selectively-sensitized silver halide layers having image-dye forming materials associated therewith, and a novel interlayer, separating the silver halide layers, comprising a polymeric hydroxamic acid polyvalent metal salt which serves as a barrier to the migration of solubilized image-dye forming material until it is rendered permeable to the image-dye forming material subsequent to contact with a sequestering agent for the polyvalent metal of the salt barrier.
