ABSTRACT:
A silver halide photographic light-sensitive material containing a diffusion resistant coupler, a light-sensitive silver halide and at least one organic metal complex represented by the following general formula (I) in the same layer or different layers on a support. ##STR1## wherein M represents a divalent metal atom; R.sup.1 and R.sup.2, which may be the same or different, each represents 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, or R.sup.1 and R.sup.2 may be bonded each other to form a heterocyclic ring together with the nitrogen atom; 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; and R.sup.4 and R.sup.5, which may be the same or different, each represents a hydrogen atom, a halogen atom, a hydroxy group, an amino group, a carboxylic acid group, a sulfonic acid group, an alkoxycarbonyl group, an alkyl group or an alkoxy, or R.sup.4 and R.sup.5 may be bonded to each other to form a 5-membered or 6-membered ring.
The compound represented by the general formula (I) is a precursor of a color developing agent which provides a sufficiently high color density on development and causes less desensitization and little fog or stain formation during storage of the photographic light-sensitive material containing thereof. A method of forming a color photographic image using the silver halide photographic light-sensitive material is also disclosed.
