ABSTRACT:
A color photographic light-sensitive material comprising a support having thereon at least one light-sensitive silver halide emulsion layer having associated therewith a compound encompassed by one of two general formulae which are specifically disclosed. The compound associated with the silver halide emulsion layer is an azo dye image-forming compound which provides a yellow dye image having excellent transferability and light fastness. The azo dye image forming compound is particularly suitable for use in a photographic material for a color diffusion transfer process. The disclosed material is capable of providing a transferred dye image with a high maximum image density (D.sub.max), a low minimum background density (D.sub.min), a good gradation and excellent color hue.
