Abstract (en)
[origin: US4407929A] In a color photographic recording material for the dye diffusion transfer process a transparent layer support, a light sensitive element, a light-reflecting opaque layer and an image-receiving layer form in that order a non-disconnectable assembly of layers and the light-sensitive element contains at least one silver halide emulsion layer and associated therewith an electron donor compound and a non-diffusing reducible color-providing compound that when reduced liberates a diffusible dye under alkaline development conditions. The material provides "development control on viewing" when the first part, e.g. about 2 minutes, of total development is conducted in dark and is completed at ambient light.
