Abstract
A superhigh contrast negative type silver halide photographic material, comprising a support having provided thereon at least one silver halide emulsion layer, wherein the emulsion layer or at least one other hydrophilic colloid layer contains at least one hydrazine derivative and at least one organic desensitizer having at least one water-soluble group or alkali-dissociative group. The material has a reduced sensitivity suitable for processing in a bright room while enjoying the effect of the hydrazine derivative to increase contrast.
