ABSTRACT:
In a silver halide color photographic light-sensitive material having each at least one red-sensitive silver halide emulsion layer (RL), green-sensitive silver halide emulsion layer (GL) and blue-sensitive silver halide emulsion layer (BL) on a support and further having a hydrophilic colloidal layer (AH-1) containing black colloidal silver between the support and the nearest light-sensitive silver halide emulsion layer, wherein the light-sensitive material further has a light-sensitive silver halide emulsion layer (DL) between the hydrophilic colloidal layer (AH-1) and the support, wherein the silver halide emulsion layer (DL) comprises at least one light-sensitive silver halide emulsion, and optical information is recorded by an exposure to light through the support, and the light-sensitive emulsion layer (DL) or its adjacent layer has a color-forming coupler.
