Silver halide photographic light-sensitive material excellent in treatment stability

A silver halide photographic light-sensitive material comprising a support having thereon photographic component layers comprising a blue-sensitive silver halide emulsion layer, a green-sensitive silver halide emulsion layer and a red-sensitive silver halide emulsion layer, wherein said red-sensitive silver halide emulsion layer contains silver halide grains comprising not less than 90 mol % of silver chloride, a compound represented by the following formula [S] and a cyan coupler represented by the following formula [I]:

• ##STR132## wherein Ar is an arylene group or a cycloalkylene group;
• R.sub.A is an alkyl group, an alkoxy group, a carboxyl group or its salt, a sulfo group or its salt, a hydroxyl group, an amino group, an acylamino group, a ##STR133## group, an --NHSO.sub.2 R" group or an ##STR134## group, R' and R" being a hydrogen atom an alkyl group or an aryl group, respectively, and M is a hydrogen atom, an alkali metal atom or an ammonium group;
• ##STR135## wherein R.sup.1 is an alkyl group or an aryl group;
• R.sup.2 is an alkyl group, a cycloalkyl group, an aryl group or a heterocyclic group;
• R.sup.3 is a hydrogen atom, a halogen atom, an alkyl group or a alkoxy group, R.sup.3 and R.sup.1 being allowed to form a ring by coupling with R.sup.1 ;
• Z represent a hydrogen atom or a group capable of being splitted off upon reaction with the oxidized product of an aromatic primary amine color developing agent.
