ABSTRACT:
A silver halide photographic light-sensitive material containing a diffusion resistant coupler, a light-sensitive silver halide and at least one compound represented by the following general formula (I) in the same layer or different layers on a support. ##STR1## wherein R.sup.1 and R.sup.2 independently represent an alkyl group having from 1 to 5 carbon atoms, a hydroxyalkyl group having from 1 to 5 carbon atoms, an alkoxyalkyl group having from 2 to 10 carbon atoms or an alkylsulfonamidoalkyl group having from 2 to 10 carbon atoms; R.sup.3 represents a hydrogen atom, an alkyl group having from 1 to 5 carbon atoms or an alkoxy group having from 1 to 5 carbon atoms; X represents a hydrogen atom or a group capable of being removed with alkali; Y represents ##STR2## and Z represents an alkyl group, an alkenyl group, an aryl group or a heterocyclic group.
The compound represented by the general formula (I) is a novel precursor of a color developing agent which provides a sufficiently high color density on development and causes less desensitization as well as less fog or stain formation during storage of any photographic light-sensitive material containing it. A method of forming a color photographic image using the silver photographic light-sensitive material is also disclosed.
