Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a photographic light-sensitive material having a silver halide light-sensitive layer on a support and a method for processing the same, and more particularly to a silver halide photographic light-sensitive material capable of obtaining high contrast and a method for processing the same. .

[0002]

2. Description of the Related Art The photolithography process includes a process of converting a continuous-tone original into a halftone dot image. In this step, a technique based on infectious development has been used as a photographic technique capable of reproducing an ultrahigh contrast image.

The lithographic silver halide photographic light-sensitive material used for infectious development has, for example, an average grain size of 0.2 μm, a narrow grain distribution and a uniform grain shape, and a high silver chloride content (at least 50 mol). % Or more) of silver chlorobromide emulsion.
By treating this lith-type silver halide photographic light-sensitive material with an alkaline hydroquinone developer having a low sulfite ion concentration, an image with high contrast, high sharpness and high resolution can be obtained.

However, since these lith-type developers are susceptible to aerial oxidation, their preservative properties are extremely poor.
Even in continuous use, it is difficult to keep the development quality constant.

There is known a method of rapidly obtaining a high-contrast image without using the lith developer. For example, as disclosed in U.S. Pat.No. 2,419,975, JP-A-51-16623 and JP-A-51-20921, JP-A-56-106244, a hydrazine derivative is contained in a silver halide light-sensitive material. is there.

According to these methods, the concentration of sulfite ion can be kept high in the developing solution, and processing can be carried out in a state where the homeostasis is enhanced. However, in these methods, in order to fully exhibit the high contrast property of the hydrazine derivative, it was necessary to perform processing with a developer having a pH of 11 or more. A developer having a high pH of 11 or more is more stable than a lith developer which is susceptible to oxidation of the developing agent when exposed to air, but oxidation of the developing agent often fails to obtain a high contrast image. In order to compensate for this drawback, JP-A-63-29751 and European Patents 333,435 and 345,0
No. 25 discloses a silver halide photographic light-sensitive material containing a contrast-increasing agent capable of increasing the contrast even in a developer having a relatively low pH.

However, when a silver halide photographic light-sensitive material containing such a contrast-increasing agent is processed with a developer having a pH of less than pH 11, the contrast becomes insufficient and satisfactory halftone dot performance cannot be obtained. The current situation.

On the other hand, European Patent 364,166 and Japanese Patent Laid-Open Nos. 62-222241, 60-140340, 62-250439 and 62-
No. 280733 and the like describe nucleation accelerators for accelerating the increase in contrast, and it is true that the addition of these compounds to the emulsion layer improves the halftone dot performance, but sand-like dots are present in the halftone dots. It has been found that pin-shaped fog, so-called black spots, occurs and the quality of the halftone dot image is impaired.

Therefore, there is a demand for a light-sensitive material using an effective contrast-increasing agent and a nucleation accelerator that solves the above problems.

[0010]

The object of the present invention is to provide a pH1
A silver halide photographic light-sensitive material and a processing method thereof which have a high photographic property even when processed with a developing solution of less than 1 and suppress fogging occurring in a halftone dot image and have further better halftone dot performance.
