Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention relates to a photographic light-sensitive material containing a novel compound q'syr that can make photographically useful groups available during development processing.

(Prior art) By color-developing a silver halide color photographic material, an oxidized aromatic-amine color developing agent and a coupler react to form indophenol, indoaniline,
It is known that indamine, azomethine, phenoxazine, phenazine and similar dyes can be produced to form color images. In this method, a subtractive color method is usually used for color reproduction, with silver halide emulsions selectively sensitive to blue, green, and red, and yellow, which has a relationship with the remaining colors, respectively.
Magenta, and cyan color image forming agents are used. To form a yellow image, for example, acylacetanilide or dibendiylmethane couplers are used, and to form a magenta image, pyrazolone, pyrazolobenzimidazole, cyanoacetophenone! or indacylon couplers are used, and phenolic couplers, such as phenols and naphthols, are used primarily to form a cyan image.

It has been known that couplers are used not only to form dye images but also to release photographically useful groups. For example, US patent cylinder 3. ．．
227.33 Hiro No. 3. /4tr, Issues 01 and 2 and the Journal of the Amer.
Coupler that releases a development inhibitor or a dye from the coupling position is described in vol. 72 (7930), p. 7333 of Ican Chemical Society, Vol. 72 (7930), page 7333.

Also, the US patent cylinder is 3.70! , No. 101 discloses couplers that are capable of releasing bleach inhibitors from the coupling site after reaction of the coupler with oxidized developing agent. Furthermore, recently, Japanese published patent 37-/30g≠j
No. 1, No. 1, No. 1, No. 1, No. 1, No. 1, No. 1, No. 1, No. 2003, No. 1, No. 1, No. 1, No. 1, No. 1, No. 1, No. 1, No. 1, No. 1, No. 1, No. 1, No. 1, 2006, and 1, No. 1, No. 1, No. 1, No. 1, No. 1, 2006, and 1, No. 1, No. 1, No. 1, No. 1, 2 and 3, 2, and 3, discloses couplers that release a caprase agent from the coupling site after the reaction between the developed oxidized herbal drug and the coupler.

Compounds that do not produce dyes but release photographically useful groups by reacting with oxidized crude drugs for development have also been known. For example, US Patent No. 3, 273, discloses indanone-type couplers that release development inhibitors.

As is well known from the above-mentioned specifications, the compound vIf released on a photographically useful group is used for the purpose of improving color reproducibility, improving graininess, improving sharpness, or increasing sensitivity, respectively.

It is common knowledge in the art that for compounds that release photographically useful groups, techniques for adjusting the rate of total release and degree of diffusion into the emulsion are more important than adjusting the photographic action tJ4 of the photographically useful groups. be. It is also disclosed in Jter 362≠ that the greater the diffusibility of the released development inhibitor, the greater the sharpness improvement. As one such technique, an example of a coupler that releases a photographically useful group with a timing group is disclosed in US Pat. No. 9.2, No. 62. This coupler is useful for photography.
Compared to the type of coupler directly bonded to the t-coupling position, an increase in the coupling rate has been observed and it has a certain degree of performance. However, there are drawbacks such as decomposition during storage of the film after application, resulting in decreased functionality or desensitization, and increased turnip IJk. This is due to the fact that when the film is stored, under humid conditions, hydrolysis at the bonded portion of the electrophilic group is unavoidable, and as a result, the photographically useful group is released. Because photographically useful groups are structurally designed to diffuse for their purpose, they diffuse into other layers and come into contact with silver halide, thereby exerting a full influence on photographic properties. It is fatal that photographic effects occur during film storage, and improvements have been desired.

In order to improve these shortcomings and to have even better photographic performance, JP-A-10-1999/ZA 37.30
A series of compounds are known.

These are compounds in which the compound released after a coupling reaction with an oxidized developed crude drug undergoes a redox reaction with another molecule of an oxidized developed crude drug, thereby releasing all photographically useful groups. Due to the mechanism of action in which the photographically useful group is released only after two reactions with the oxidized developing agent, these compounds have the ability to control the diffusion range of the photographically useful group depending on the concentration of the oxidized developing agent. Can be done.

For this reason, they exhibit excellent photographic performance.

Furthermore, due to its structural characteristics, it is extremely stable against air oxidation and hydrolysis.

However, in the above-mentioned compounds, the final release rate of the photographically useful group was often too low. For this reason, it has not always been possible to effectively express the photographically useful group in terms of photographic function.

(Object of the Invention) Therefore, an object of the present invention is to provide a novel compound which has excellent storage stability and which can release photographically useful groups at an optimum rate during development. Another object of the present invention is to provide a color photographic material that contains the compound of the present invention and has excellent image quality in terms of graininess, sharpness, color reproducibility, and the like.

(Structure of the Invention) These objects of the present invention have been achieved by a silver halide photographic light-sensitive material characterized by containing a compound represented by the following general formula (I).

General formula (I) In the formula, Aii represents a group that is cleaved by reaction with an oxidized developing agent, and B is a nucleophilic group represented by Nu that reacts with the oxidized developing agent and is then linked to B.

It is the reaction between B-(L 2)w-4)UG and T■,
3 Nu is destroyed by the subsequent cleavage reaction of (L2) w-PUG. These two reactions are what characterize all the excellent effects of the present invention. That is, in the first stage reaction, this reaction is a secondary reaction between T■ and B (L2)WPUG, and the rate of the 3Nu reaction depends on the concentration of each. Therefore T
In places where a large amount of (2) is generated, PUG'i will eventually be generated quickly.

On the other hand, in contrast, only a small amount of T■ is generated and it is formed late. Due to such an action mechanism in which the production concentration of PUG is controlled depending on the concentration of T, the full effect of PUG can be expressed.

In addition, in the second stage reaction, the nucleophilic group Nu that can cleave (L2) w-PUG is linked to B through sL3, so this cleavage reaction proceeds quickly as an intramolecular reaction. . Therefore, (L2)w-)'UG can be efficiently and quickly released, and therefore the action of PUG can be effectively expressed.

This black-and-white developer contains known black-and-white image agents such as dihydroxybenzenes such as hydroquinone, 3-pyrazolidones such as phenyl-3-pyrazolidone, or amine phenols such as N-methyl-p-aminophenol. They can be used alone or in combination.

The pH of these color developing solutions and black and white developing solutions is generally 2 to 1. The amount of replenishment of these developing solutions depends on the color photographic light-sensitive material to be processed, but it is generally less than 1) Jl per square meter of light-sensitive material, and it is important to reduce the bromide ion concentration in the replenisher. 30
It can also be set to 0- or less. When reducing the amount of replenishment, it is preferable to prevent evaporation of the liquid and air oxidation by reducing the area of contact with the air in the processing tank. Furthermore, the amount of replenishment can be reduced by using means for suppressing the accumulation of bromide ions in the developer.

After color development, the photographic emulsion layer is usually bleached.

The bleaching process may be carried out simultaneously with the fixing process.
(fixing process) may be performed separately. Furthermore, in order to speed up the processing, a processing method may be used in which bleaching is followed by bleach-fixing. Furthermore, treatment with two consecutive bleach-fixing baths, fixing treatment before bleach-fixing treatment, or bleaching treatment after bleach-fixing treatment can be carried out as desired depending on the purpose. Examples of bleaching agents include iron (■) and cobalt (II).
Compounds of polyvalent metals such as I), chromium (■), and copper (If), peracids, quinones, and nitro compounds are used.

Typical bleaching agents include 7-erythyanide; dichromate; organic complex salts of iron (In) or cobalt (■), such as ethylenediaminetetraacetic acid, diethylenetriaminepentaacetic acid, cyclohexanediaminetetraacetic acid, methyliminodiacetic acid, l,3-diaminoprol; Aminopolycarboxylic acids such as O-pantetraacetic acid, glycol ether diamine tetraacetic acid, or complex salts of citric acid, tartaric acid, malic acid, etc.; persulfates: bromates; permanganates: nitrobenzenes, etc. can be used. . Among these, aminopolycarboxylic acid iron(III) complex salts and persulfates, including ethylenediaminetetraacetic acid iron(III) complex salts, are preferable from the viewpoint of rapid processing and prevention of environmental pollution. Furthermore, aminopolycarboxylic acid iron(III) complexes are particularly useful in both bleach and bleach-fix solutions.

The pH of the bleach or bleach-fix solution using these aminopolycarboxylic acid iron (III) complex salts is usually r, z to t, but in order to speed up the processing, it can be processed at an even lower pH. .

A bleach accelerator may be used in the bleaching solution, bleach-fixing solution, and their prebaths, if necessary.

The silver halide color photographic light-sensitive material of the present invention is generally subjected to water washing and/or stabilization steps after desilvering treatment.

The amount of water used in the washing process depends on the characteristics of the photosensitive material (for example, depending on the materials used, such as couplers), the application, the temperature of the washing water, the number of washing tanks (number of stages), the replenishment method such as countercurrent flow, turbid flow, etc., and various other conditions. Can be set over a wide range. Among these, the relationship between the number of washing tanks and the amount of water in the multistage countercurrent method is
