ABSTRACT:
A multilayer color photographic material suitable for optically recording sound images on a sound track area formed thereon is composed of a support having coated thereon at least one silver halide emulsion layer containing a color coupler in at least a 40 mol% excess of the stoichiometric amount of the coupler to the silver halide contained in the emulsion layer and at least one silver halide emulsion layer containing a color coupler in an amount less than 40 mol% excess of the stoichiometric amount of the coupler to the silver halide in the emulsion layer.
The color photographic material is suitably processed by a color intensification development process.
