Abstract: An improved silver halide photographic material that has at least one silver halide emulsion layer on a support and that contains a hydrazine derivative in said emulsion layer or an adjacent layer. The improvement is that said emulsion layer or at least one of the other hydrophilic colloidal layers contains at least one of the compounds represented by the following general formulas (I) and (II): ##STR1## wherein R.sub.1 and R.sub.1 ' are each a group selected from among a substituted or unsubstituted alkane residue, an alkene residue, a benzene residue, a cyclohexane residue and a nitrogenous heterocyclic residue; R.sub.2 is a substituted or unsubstituted alkyl group; R.sub.3, R.sub.3 ', R.sub.4 and R.sub.4 ' are each a hydrogen atom or a substituted or unsubstituted methyl group, provided that R.sub.3 and R.sub.4 or R.sub.

Abstract: A silver halide photographic light-sensitive material suitable for photomechanical process is disclosed. The light-sensitive material comprises a support and a silver halide emulsion layer and the emulsion layer or a layer adjacent to the emulsion layer contains a compound represented by formula 1, 2 or 3 and a compound represented by formula 4 or 5. ##STR1## The light-sensitive material give extreme high contrast images by processing usung a stable developer and is inhibited from producing pepper fog.

Abstract: The improve silver halide photographic material contains a specified hydrazide compound and a specified polyoxyethylene based compound and is capable of providing high-contrast image with high sensitivity in a rapid and consistent way.
