ABSTRACT:
A light-sensitive silver halide color photographic material, which comprises a cyan coupler for photography represented by the formula [IA] or [IB] shown below in the light-sensitive emulsion; ##STR1## wherein R.sup.1 is a group having a bulk sufficient to impart diffusion resistance to said coupler; R.sup.2 and R.sup.3 each represent a hydrogen atom or a halogen atom, at least one of R.sup.2 and R.sup.3 being a halogen atom; R.sup.2' represents an alkyl group, a cycloalkyl group, an alkenyl group or an aryl group; R.sup.3' represents a halogen atom; and Z represents a hydrogen atom or a group eliminable during the coupling reaction with the oxidized product of a color developing agent.
According to the material of this invention, good spectral absorption characteristics can be exhibited and a cyan dye image can be given without dye loss even by use of a bleaching bath or bleach fixing bath which is fatigued after running.
