Abstract

Abstract A color photographic cine or TV film on which a sound recording band or track can be formed without the necessity for a specific additional treatment comprising a film base having thereon at least a silver halide emulsion layer containing a coupler capable of forming a dye by the coupling reaction with the oxidation product of an aromatic primary amino developing agent, and at least one of the emulsion layers of the color photographic material containing a bleach inhibitor in only the portion defined as the sound recording track.
