Abstract

PURPOSE:To maintain the high sensitivity and to prevent fog by incorporating a compound having a specified anti-fogging mercapto group which is table in neutral and acidic regions and is activated in an alkaline region during development into a silver halide emulsion layer. CONSTITUTION:A compound represented by the formula is used as an anti- foggant. In the formula, A is an anti-fogging mercapto-heterocyclic group, R is H, R<1> is H, alkyl or substituted alkyl, and R2 is H, halogen, hydroxy, alkyl or alkoxy. The heterocyclic group may be tetrazole, benzoxazole, benzothiazole or benzoimidazole. The anti-foggant is incorporated into a silver halide emulsion layer or a colloidal layer on the emulsion layer. Thus, a photosensitive material contains the anti-foggant, so the high sensitivity is maintained during develop ment, and fog can be prevented.

(B) Prior art and its problems Silver halide photographic materials are developed under strong conditions, for example, at relatively high temperatures or using highly active developers.
When developing for an extremely short time, there is a risk that even silver halide grains having no latent image nuclei may be reduced.

As such, a fundamental disadvantage of adding cyclic mercapto compounds, etc., which are active against overdeveloped capri, directly to silver halide emulsions is that they are not fully active from the time of addition. That is, it is already fully active during the manufacturing process, during the storage period of the photographic material, and during the development stage.

In order to solve this problem, the mercapto groups of these compounds are protected with suitable hydrolyzable groups, so that their effects are not desired during the period (the entire period before development, including the manufacturing process). Attempts have already been made to regenerate their active form by alkaline hydrolysis during the development process. Such substituents are usually thioesters or thioethers of the mercaptocapric inhibitor.

However, although these thioesters are hydrolyzed in the alkaline medium of the developer, they have the disadvantage that partial hydrolysis gradually proceeds even in the neutral or weakly acidic pH range. Therefore, these thioester-type anticapri agents can be added to emulsions in an inactive form, but if the emulsion preparation process or the storage period of the photographic material is optically long, undesirable desensitizing effects may occur due to partial hydrolysis. to cause

Although the compounds disclosed in No. 73,796 are indeed stable in neutral or weakly acidic media, during the development process the original mercaptocapric inhibitor is not regenerated at all or only gradually. Therefore, it has the disadvantage of not being able to effectively prevent over-existence of mound capri.
