ABSTRACT:
A silver halide photographic light-sensitive material is described, which comprises a support having provided thereon a light-sensitive silver halide emulsion layer, wherein the silver halide photographic material contains a compound having been blocked by a metal chelate and capable of releasing a photographically useful compound therefrom through a reaction of the metal chelate moiety with a water-soluble chelating agent capable of forming a metal chelate having a higher stability constant on development. A method for forming an image is also described, which comprises processing, after imagewise exposure, a silver halide photographic light-sensitive material with a processing solution containing a nitrogen-containing heterocyclic carboxylic acid-base chelating agent.
