    摘要： There is disclosed a novel silver halide photosensitive color photographic material comprising a coupler which consists of a coupling component (A) which is capable of causing a coupling reaction with an oxidized color developing agent and a substituent component bonded at the coupling position of said coupling component (A), which substituent component is capable of being split off on coupling reaction, the improvement characterized in that said substituent comprises a coupling component (B) which can undergo coupling reaction with an oxidized color developing agent when released from said coupling component (A) and a photographically useful component which is capable of being released on coupling reaction of said coupling component (B).The color photographic material according to the present invention provides graininess, sharpness and color reproducibility which is sufficiently competent to the requirement of further miniturization of film size by use of a coupler having novel functions.
