High-contrast silver halide photographic material

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.

What is claimed is: 
     
       1. In a silver halide photographic material having at least one light-sensitive silver halide emulsion layer, the improvement wherein said photographic material contains at least one of the compounds represented by the formula IIIa shown below and at least one compound represented by the formula IV also shown below: ##STR36## where R 2 , R 3  and R 4  each represents a hydrogen atom, an optionally substituted aliphatic, aromatic, heterocyclic, alkoxy or aryloxy group; R 5  represents a divalent aromatic group; R 6  represents an optionally substituted alkyl, alkoxy or amino group; and Y represents a sulfur or oxygen atom; ##STR37## where R 1  is a hydrogen atom or a substituted or unsubstituted aromatic group; and n is an integer of 10-200; and wherein said photographic material contains a hardener. 
     
     
       2. A silver halide photographic material according to claim 1 wherein the compound represented by the formula (IV) is at least one compound selected from among the following compounds IV-3, IV-9 and IV-10. ##STR38## 
     
     
       3. A silver halide photographic material according to claim 1 wherein the silver halide contained in the silver halide emulsion layer is silver bromide or silver iodobromide. 
     
     
       4. A silver halide photographic material according to claim 1 wherein the silver halide contained in the silver halide emulsion layer is composed of grains having an average size of 0.1-1.0 μm, with at least 75% of the total grains having a grain size ranging from 0.7 to 1.3 times the average grain size.
