Description

Detailed Description of the Invention (Field of Industrial Application) The present invention relates to a silver halide photographic light-sensitive material that provides extremely sharp negative images, high sensitivity negative images, and excellent halftone image quality; The present invention relates to a silver halide photographic material that forms a positive photographic image, and particularly to a photographic material containing a novel compound as a nucleating agent for silver halide.

Ultra-high contrast photographic characteristics with gamma exceeding 10 are negative images,

It is extremely useful for photographic reproduction of continuous tone images (dot images) or reproduction of line drawings.

Conventionally, for this purpose, the content of silver chloride was set at 50%.
A common method is to use a silver chlorobromide photographic emulsion with a mol%, preferably more than 75 mol%, and develop it with a hydroquinone developer with an extremely low effective concentration of sulfite ions (usually 0.1 mol/i or less). It was used in However, with this method, the concentration of sulfite ions in the developer is low, so
The developer is extremely unstable and cannot be stored for more than 3 days.

Furthermore, all of these methods require the use of chlorobromide emulsions with a relatively high silver chloride content, making it impossible to obtain high 5 degrees. Therefore, there has been a strong desire to obtain ultra-high contrast photographic characteristics useful for reproducing halftone images and line drawings by using emulsions with high sensitivity and stable developers.

No. 4,323.643, etc., disclose silver halide photographic emulsions that use stable developing solutions and provide extremely high-contrast photographic characteristics, but the acylhydrazine compounds used therein are It has been found that it has some drawbacks.

In other words, these conventional hydrazines are known to generate nitrogen gas during the development process, and these gases collect in the film and form bubbles that damage the photographic image. This is because the leakage into other photographic materials has an adverse effect on other photographic materials.

It has been known to increase the molecular weight of a nucleating agent to make it diffusion resistant as a means of preventing it from leaking into the development processing solution. It turns out there is a problem. That is, when a coating solution containing a nucleating agent is aged, precipitates form in the coating solution, deteriorating filtration properties, and furthermore, photographic performance changes.

In addition, when these conventional hydranones are required in large quantities to increase contrast, or when a particularly high degree of hydranone is required for the performance of the sensitive material, other sensitization techniques (such as chemical sensitization) may be used. U.S. Pat. No. 4.272.606 and U.S. Pat. No. 4,241,164
When used in combination with compounds that promote exacerbation (such as the addition of compounds that promote exacerbation as described in the above issue), in general, exacerbation over time and increased strength may occur during storage.

Therefore, there has been a desire for a compound that can reduce the generation of bubbles and leakage into the developer, has no problems with stability over time, and can provide extremely high-contrast photographic properties with the addition of a very small amount. .

Also, U.S. Patent No. 4,385.108, U.S. Pat.
．． No. 929 and No. 4,243,739 describe that extremely hard negative gradation photographic properties can be obtained by using hydrazines having substituents that are easily adsorbed to silver halide grains. However, among these hydrazine compounds having an adsorptive group, those specifically mentioned in the above-mentioned known examples have a problem in that they cause loss of energy over time during storage. Therefore, it was necessary to select a compound that would not cause such problems.

On the other hand, there are various direct positive photography methods, including a method in which silver halide grains that have been fogged in advance are exposed to light in the presence of a 15-agent and then developed, and a method in which silver halide grains have photosensitive nuclei inside them. The most common method is to develop a silver emulsion in the presence of a nucleating agent after exposure.The present invention relates to the latter method.

Silver halide emulsions that mainly have S photonuclei inside the silver halide grains and in which latent images are mainly formed inside the grains are called internal layer image type silver halide emulsions. These grains can be distinguished from silver halide grains which form latent images on the surface.

A method of directly obtaining a positive image by surface developing an internal layer image type silver halide photographic emulsion in the presence of a nucleating agent, and a photographic emulsion or light-sensitive material used in such a method are known.

In the above-mentioned method for obtaining a direct positive image, the nucleating agent may be added to the developer, but it may also be added to the photographic emulsion layer or other appropriate layer of the light-sensitive material so that it is adsorbed to the surface of the silver halide grains. Sometimes better inversion characteristics can be obtained.
