ABSTRACT:
A color photographic light-sensitive material which comprises a support having coated thereon at least one light-sensitive silver halide emulsion layer containing a yellow dye-forming coupler, at least one light-sensitive silver halide emulsion layer containing a cyan dye-forming coupler, at least one light-sensitive silver halide emulsion layer containing a magenta dye-forming coupler and at least one light-sensitive silver halide emulsion layer containing at least one non-diffusible silver bleach inhibitor selected from the group consisting of a nitrogen-containing heterocyclic compound having a thioether bond and a heterocyclic compound containing one or more nitrogen atoms which combine with a group containing 11 or more carbon atoms to form a quaternary salt, in combination with one or more heterocyclic thione compounds having a thione group which is not capable of forming a mercaptan. The color photographic light-sensitive material provides silver images for sound recording without any specific processing steps as are conventionally used to form sound tracks.
