ABSTRACT:
A photographic light-sensitive element having at least one light-sensitive silver halide layer and a dye image forming non-diffusible material which, upon a redox reaction under alkaline conditions releases a diffusible cyan dye or precursor thereof wherein said material is ##STR1## wherein Car represents a carrier component having at least on Ball group as a part thereof which alone or together with other such groups in said Car renders said compound non-diffusible during development in alkaline processing solution, said Car being capable of releasing from said compound a diffusible dye or the precursor thereof as the result of a redox reaction under alkaline conditions:
