摘要:
There is disclosed a light-sensitive silver halide color photographic material containing novel cyan coupler which comprises a light-sensitive silver halide color photographic material having at least one silver halide emulsion layer on a support, characterized in that at least one layer of the silver halide emulsion layer contains at least one cyan coupler represented by the formula (I) shown below: ##STR1## wherein R.sub.1 and R.sub.2 each represent an alkyl group, an aryl group, a heterocyclic group, a dialkylamino group, an anilino group, an alkoxy group or an arloxy group; R.sub.3 represents a hydrogen atom or an alkyl group; R.sub.4 represents a hydrogen atom, an alkyl group, an aryl group, A R.sub.5 CO--group or a R.sub.5 SO.sub.2 --group; provided that R.sub.3 and R.sub.4 cannot be hydrogen atoms at the same time; R.sub.5 represents a hydrogen atom, an alkyl group, an aryl group, a dialkylamino group, an anilino group, an alkoxy group or an aryloxy group; and X represents a hydrogen atom or an eliminatable group through the reaction with the oxidized product of a color developing agent.
