PRODUCTION OF SILVER HALIDE PHOTOGRAPHIC SENSITIVE MATERIAL

摘要

PURPOSE: To provide a method for stably producing a photosensitive material for a bright room being supercontrasty, excellent in safe-light safety and not causing safe light fogging. CONSTITUTION: A silver halide photographic sensitive material contg. the silver halide emulsion grains having 0.1-0.05μm average diameter and a hydrzine derivative is produced while keeping the silver halide emulsion contg. the grains at <=45 deg.C from the formation of the grain until the emulsion is applied in process 1. A silver halide photographic sensitive material contg. the silver halide emulsion grains having 0.1-0.05μm average diameter and a hydrazine derivative is produced by incorporating at least one kind among benzotriazole and its derivatives into the sensitive material at the time of redissolution after the desalting and water washing in the course of the production of a silver halide emulsion contg. the grains in process 2. Otherwise, both processes 1 and 2 are combined to produce the sensitive material.
