Abstract
Disclosed are a silver halide photographic light-sensitive material comprising silver halide containing a metal complex having a cyanide ligand in a silver halide emulsion layer and comprising a hydrazine compound having an onium group in the molecule, and a method of developing the silver halide photographic light-sensitive material with a developer having a pH of 9.0-11.0. The silver halide photographic light-sensitive material of the present invention can provide high sensitivity, high processing stability and high contrast images.
Claims18
A silver halide photographic light-sensitive material comprising at least one silver halide emulsion layer on a support, wherein the silver halide emulsion layer contains silver halide containing a metal complex having a cyanide ligand, and the silver halide photographic light-sensitive material contains a hydrazine compound having an onium group in the molecule represented by the following formula:
- wherein —G1—R2 represents —COCF2H or —COCF2CF2COOM (M represents a hydrogen atom or a counter cation), J represents an alkylene group, and Q represents a pyridinium group or a quinolinium group.
A silver halide photographic light-sensitive material comprising at least one silver halide emulsion layer on a support, wherein the silver halide emulsion layer contains silver halide containing a Group VIII metal compound, and the silver halide photographic light-sensitive material contains a hydrazine compound having an onium group in the molecule represented by the following formula:
- wherein —G1—R2 represents —COCF2H or —COCF2CF2COOM (M represents a hydrogen atom or a counter cation), J represents an alkylene group, and Q represents a pyridinium group or a quinolinium group.
A monochromatic silver halide photographic light-sensitive material which is developed with a developer having a pH of 9.0-11.0 and a replenishing amount of 330 mL/m2 or less for the developer, wherein the monochromatic silver halide photographic light-sensitive material has one or more hydrophilic colloid layers on a support, at least one of the hydrophilic colloid layers is a silver halide emulsion layer, and the monochromatic silver halide photographic light-sensitive material contains at least one kind of a hydrazine compound having an onium group in the molecule represented by the following formula:
- wherein —G1—R2 represents —COCF2H or —COCF2CF2COOM (M represents a hydrogen atom or a counter cation), J represents an alkylene group, and Q represents a pyridinium group or a quinolinium group.
A monochromatic silver halide photographic light-sensitive material which is developed with a developer having a pH of 9.0-11.0, wherein the monochromatic silver halide photographic light-sensitive material has one or more hydrophilic colloid layers on a support, at least one of the hydrophilic colloid layers is a silver halide emulsion layer, and the monochromatic silver halide photographic light-sensitive material contains at least one kind of a hydrazine compound having an onium group in the molecule represented by the following formula:
- wherein —G1—R2 represents —COCF2H or —COCF2CF2COOM (M represents a hydrogen atom or a counter cation), J represents an alkylene group, and Q represents a pyridinium group or a quinolinium group.
