Abstract
Abstract A silver halide photographic light-sensitive material which comprises at least one of those pyrazole compounds represented by the following general formula: ##STR1## wherein A is a group which can be eliminated in a photographic process condition; X is ##STR2## wherein R 5 is a hydrogen atom or an alkyl, an aryl, an acyl or a sulfone group, which R 5 group may combine together with R 1 to form a condensed ring; R 1 is a hydrogen atom or an alkyl, an aryl, an acyl, a sulfone, an alkoxy, or a heterocyclic residue; R 2 is a hydrogen atom or an alkyl, an aryl, an alkoxy, an amino, an acid amide, a sulfonamide, a carboxyl, an alkoxycarbonyl, a carbamoyl, a cyano, or a halogenated alkyl group, R 3 and R 4 each is a hydrogen atom or an alkyl or an aryl group; and PUG is a photographically useful group which is released after elimination of the A group in a photographic processing condition and which has a hetero atom directly combined with the carbon substituted in the fourth position of the pyrazole nucleus.
