Title:
DEVELOPMENT PROCESSING METHOD FOR SILVER HALDE PHOTOGRAPHIC SENSITIVE MATERIAL
Document Type and Number:
Japanese Patent JP2684257
Kind Code:
B2
Abstract:
PURPOSE: To improve the blackness of image silver without causing desensitization in the case of rapid processing of an emulsion high in sensitivity by processing the silver halide photographic sensitive material with a developing solution containing a specified compound.
CONSTITUTION: This silver halide photographic sensitive material uses at least one kind of silver halide emulsion containing silver halide grains having an average grain diameter of ≤0.5μm in terms of spheres or flat silver halide grains having an average grain thickness of ≤0.25μm and an aspect ratio of ≥3, and it is processed with the developing solution containing the compound represented by formula in which M is H or an alkali metal atom or the like; L is a divalent organic group comprising alkylene, alkenylene, ether, or the like alone or in combination; X is an amino or ammonium group each optionally alkylated, hydroxy, or an optically substituted heterocyclic group; and n is 0 or 1.
