Photographic dye diffusion transfer process
Non-diffusible dye-providing components which may be used in association with a silver halide emulsion layer and on development yield diffusible yellow dyes of improved light fastness are cyanalkyl aminoazo dyes of the formula (I) in which A1 represents oxidizable carrier residue; D represents a het...
