Abstract
Disclosed is a silver halide color photographic light-sensitive material comprising a support and thereon a blue-sensitive silver halide emulsion layer, a green-sensitive silver emulsion layer and a red-sensitive silver halide emulsion layer, wherein said green-sensitive emulsion layer contains at least one coupler represented by Formula M-I and at least one of a non-color-forming compound represented by Formula A-1 or A-2: ##STR1## wherein R represents a hydrogen atom or a substituent; X represents a hydrogen atom or a substituent capable of splitting upon making a reaction with an oxidized product of a color developing agent; and Z represents a group consisting of metal atoms necessary to form a nitrogen-containing heterocyclic ring: Formula (A-1) EQU R.sub.21 --NHSO.sub.2 --R.sub.22 wherein R.sub.21 and R.sub.22 represent each a hydrogen atom, an alkyl group, a cycloalkyl group, an alkenyl group, a cycloalkenyl group, an alkinyl group, an aryl group, a heterocyclic group, an alkoxy group, an aryloxy group, a heterocyclicoxy group, or ##STR2## wherein R.sub.23 and R.sub.24 represent each a hydrogen atom, an alkyl group or an aryl group: ##STR3## wherein R.sub.31 represents an alk…
