FIELD OF THE INVENTION The present invention relates to a silver halide photographic light-sensitive material, and more particularly to a silver halide photographic light-sensitive material suitable as a light-sensitive material for printing plate making.

[0002]

BACKGROUND OF THE INVENTION In silver halide photographic light-sensitive materials, improvement of image quality is an important issue, and in recent years, by utilizing a functional organic material which releases a development inhibitor imagewise or reverse imagewise in the development process. Image quality is being improved, and development of these functional organic materials for improving image quality is being energetically carried out.

On the other hand, silver halide photographic light-sensitive materials are required to have various image qualities depending on the purpose of use. In the silver halide photographic light-sensitive material used for printing plate making, in order to cope with the variety and complexity of printed matter, image reproducibility, specifically, line drawing reproducibility in the line drawing process, and clearness in the character shooting process. It is desired that the reproducibility, stretchability and shrinkability are good, and that the quality of characters to be removed in the returning step and the pinholes after sticking are good.

In order to solve these problems, a technique using a redox compound which releases hydrazine or an inhibitor is disclosed in JP-A-62-80640, JP-A-62-235939 and JP-A-62-235939.

However, when hydrazine is added to the silver halide photographic emulsion to make it into a high contrast, there is a problem that the suitability for stretching is deteriorated, and an inhibitor is further added to the silver halide photographic light-sensitive material containing hydrazine. When the release redox compound is contained, defects such as deterioration of high contrast, softening during storage, and deterioration of black spots occur, and the silver halide photographic light-sensitive material is satisfactory as a sensitizer for printing plate making.
