ABSTRACT:
A color photographic material is disclosed comprising a black image forming coupler substituted in the 2, 4 and/or 6 position shown by formula (I) or formula (II), where in LINK represents a divalent linking group, BALL represents a group that prevents the coupler from diffusing away from the layer containing it. X and Y each represent a hydrogen atom or a coupling-off group capable of being released upon an oxidative coupling reaction with a developing agent. The material has a good color reproduction and excellent light stability.
