ABSTRACT:
A silver halide photographic light-sensitive material containing a novel development inhibitor releasing coupler compound, capable of forming a substantially colorless product, represented by the following general formula (I): ##STR1## wherein R represents ##STR2## X represents ##STR3## --SO.sub.2 R.sub.2, --SO.sub.2 OR.sub.2, --SO.sub.2 N(R.sub.2).sub.2, --SO.sub.2 NHR.sub.2, --CN, --N.sup.+ (R.sub.2).sub.3 or ##STR4## R.sub.1 and R.sub.2 each represents an aliphatic group, an aromatic group or a heterocyclic group and further two R.sub.2 groups can combine and represent an atomic group necessary to form, together with the nitrogen atom to which they are attached, a nitrogen-containing heterocyclic group; and Y represents a group capable of being released from the compound represented by the general formula (I) upon reaction with the oxidation product of a color developing agent to provide a compound which has a development inhibiting effect and having a triazole ring bonded to the carbon atom through the nitrogen atom at the 1-position thereof.
