Light-sensitive material with coupler containing triazole coupling-off group

An aqueous alkaline developing solution containing an aromatic primary amino developing agent and a development inhibitor releasing photographic coupler represented by the following general formula (I):

• ##STR8## wherein R.sub.1, R.sub.2, R.sub.3 and R.sub.4, which may be the same or different, each represents a hydrogen atom, an aliphatic residue, an aromatic residue or a heterocyclic residue;
• and X represents a triazole ring which is released upon reaction of the coupler with an oxidation product of an aromatic primary developing agent and which exhibits development inhibiting effects, with the triazole ring being connected to the coupling position of the coupler through the nitrogen atom at the 1-position of the ring.

A method of forming images comprising developing an imagewise exposed photographic light-sensitive material comprising a support having thereon at least one silver halide emulsion layer in the presence of a development inhibitor releasing photographic coupler represented by the following general formula (I):

• ##STR9## wherein R.sub.1, R.sub.2, R.sub.3 and R.sub.4, which may be the same or different, each represents a hydrogen atom, an aliphatic residue, an aromatic residue or a heterocyclic residue;
• and X represents a triazole ring which is released upon reaction of the coupler with an oxidation product of an aromatic primary amine developing agent and which exhibits development inhibiting effects, with the triazole ring being connected to the coupling position of the coupler through the nitrogen atom at the 1-position of the ring, the said exposed material being developed with an aromatic primary amino color developing agent and the color developing agent, after being oxidized, coupling with the said coupler to form a dye image and to release a development inhibitor wherein the coupler initially present in either the said silver halide emulsion or a color developing solution.
