ABSTRACT:
A photographic silver halide light-sensitive material is disclosed. The material is comprised of a support and a photographic layer or layers on the support. The photographic layer contains at least one of the compounds represented by the general formula: A--OCH.sub.2 --Z (wherein A is a group capable of undergoing cleavage on application of alkali hydrolysis, and Z is a photographically useful group containing a nitrogen atom through which it is linked to the group A--OCH.sub.2 --). The compounds, i.e., photographically useful group precursors, as used herein are stable during the storage of the raw film and can release the photographically useful group at a controlled speed during development.
