Title:
SILVER HALIDE COLOR PHOTOGRAPHIC SENSITIVE MATERIAL
Document Type and Number:
Japanese Patent JPH01156733
Kind Code:
A
Abstract:
PURPOSE:To rapidly process the sensitive material, to improve the max. optical density of an image, and to reduce the generation of a fogging by providing a layer contg. silver halide having a high silver chloride content, a prescribed cyan coupler and a prescribed fog restrainer on the title material. CONSTITUTION:The silver halide particle having >=90mol.% of the silver chloride content is incorporated in one or more layers of the silver halide emulsion layers of the silver halide photographic sensitive material. The emulsion layer contains the imidazole type cyan coupler (for example a compd. shown by formula) and a nitrogen-contg. heterocyclic ring compd. having mercapto group (for example a compd. shown by formula II) as the fog restrainer. In formula I, R1 and R2 are each a substituting group, X is H atom or a group capable of being released by allowing to react with the oxidant of a color developing main agent, (n) is 0-5. In formula II, Ra is H atom or alkyl group, etc., Z is -NH- or -O- etc., M is H atom or a cation.
