ABSTRACT:
A silver halide photographic light-sensitive material is disclosed. The light-sensitive material comprises a support having thereon a photographic layer including a silver halide emulsion layer wherein the outermost surface of said photographic layer has a pH value of from 5.4 to 5.9 and said silver emulsion layer contains a compound represented by the following formula I; ##STR1## wherein R.sub.1 is an alkyl group, a cycloalkyl group or an aryl group; R.sub.2 is an alkyl group, a cycloalkyl group, an acyl group or an aryl group; R.sub.3 is a substituent, n is 0 or 1; X.sub.1 is a substituent capable of splitting off upon coupling reaction with the oxidation product of a color developing agent; and Y.sub.1 is an organic group. The light-sensitive material is excellent in stability during storage and gives stable photographic characteristics even when pH value of developer is varied.
