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.sub.1 and R.sub.2, which may be the same or different, each represents a hydrogen atom or an alkyl group having from 1 to 10 carbon atoms, or R.sub.1 and R.sub.2 may be bonded to each other to form a heterocyclic ring together with the nitrogen atom; R.sub.3, R.sub.4, R.sub.5 and R.sub.6, which may be the same or different, each represents a hydrogen atom, a halogen atom, a hydroxy group, an amino group, an alkoxy group, an acylamido group, a sulfonamido group, an alkylsulfonamido group or an alkyl group, or R.sub.1 and R.sub.6 or R.sub.2 and R.sub.3 may be bonded to each other to form a 5-membered or 6-membered ring; X represents HPF.sub.6 or HBF.sub.4 ; and n represents an integer from 1 to 3.
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 formation of fogs or stains 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.
