Abstract

PURPOSE:To obtain a color photosensitive material having an excellent graininess, sharpness and color reproducibility by incorporating a coupler which releases a compd. to capture a developing agent oxidant by reaction with the developing agent oxidant into said material. CONSTITUTION:The coupler expressed by the general formula (I) is incorporated into the silver halide color photosensitive material. In the equation, R and R' denote respectively an aliphat. group, arom. group or heterocyclic group, m denotes 0, 1 or 2 and two Y and two Z may be the same or different when m is 2. Any two among W, X, Y, Z and Q (when R is included) may form a cyclic structure by combining with each other. The excess developing agent oxidant generated in the stage of developing process is thus reduced and is effectively removed. The generation of mottle is prevented as individual dye clouds do not grow larger than certain extent. The graininess is thus improved.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a silver halide color photographic light-sensitive material containing a photographic coupler for improving sharpness and graininess.

(Prior art) When a silver halide color photographic material is color developed, the oxidized aromatic-grade amine color developing agent and coupler react with each other to form indophenol, indoaniline, etc.
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 imaging agents are used.

To form a yellow image, for example, an acylacetanilide or dibenzoylmethane coupler is used; to form a magenta image, a pyrazolone, pyrazolone benzimidazole, cyanoacetophenone or indacylon coupler is used, and a cyan color image. Primarily phenolic couplers, such as phenols and naphthols, are used to form images.

In recent years, with the spread of disk cameras and /10 size cameras, high image quality has become more important than ever in silver halide photographic materials, especially color photographic materials. In particular, it is important to improve sharpness and graininess.

It has been known that couplers are used not only to form dye images but also to release photographically useful groups. Compounds that release photographically useful groups are used for various purposes such as improving color reproducibility, improving graininess, improving sharpness, or increasing sensitivity.

Now, a coupler has been proposed that can release a compound that captures an oxidized herbal drug that exhibits a coloring phenomenon from the coupling position of the coupler. For example, Tokukai Sho Sko, 2r3/za,
Compounds described in the same, t7-///, 3r37, and the same No. 2-/3♂636 are known. These couplers are used for the purpose of improving graininess or controlling gradation, but their effects are weak and further improvements have been desired. It has also been found that the scavengers for the oxidized developing agent released by these known couplers not only have a weak scavenging ability but also have low diffusivity. Therefore, it was not possible to improve the sharpness, and it was also not possible to obtain a multilayer effect by diffusing into other layers.

(Problems to be Solved by the Invention) Therefore, an object of the present invention is to improve graininess and sharpness by incorporating a novel coupler that releases a compound that captures an oxidized developing agent by reaction with the oxidized developing agent. Another object of the present invention is to provide a color photographic material that is excellent in color reproducibility due to a multilayer effect.

(Means for Solving the Problems) The above object has been achieved by a silver halide color photographic light-sensitive material containing a coupler represented by the following general formula (r).

General formula (1) % formula %) In the formula, A represents a coupler residue whose bond with an oxygen atom is cleaved by reacting with an oxidized developing agent, W represents a substituted or unsubstituted methine group, X, At least 7 of Y and 2
One represents a nitrogen atom, the other X, Y and Z represent a substituted or unsubstituted methine group, Q represents a 10H group, -NH
S O2R group, -NH2, R and R' each represent an aliphatic group, an aromatic group, or a heterocyclic group, m represents θ,/or co, and when m is 2, λ Y12 2 are the same But it could be something different. Also, w, x, y, 2
and Q (when R is included) may be connected to form a cyclic structure.

The compound of general formula [1] shows the opposite reaction with the oxidized herbal drug! The reducing action of the leaving group which is released by some means is, for example, Ange
w, Chem, Int, Ed, /7, F73~Fr
This can be explained by the general structural rule described in &(/ri2♂). In particular, the reducing agent included in the invention is useful because it exhibits appropriate reducing power in photographic systems.

When the coupler of the present invention is used, excess oxidized developing agent generated during development can be reduced and effectively removed. This prevents individual pigment clouds from growing beyond a certain level, prevents the occurrence of mottles, and improves graininess. Furthermore, when the coupler of the present invention was used, edge effects and interlayer effects were observed when the reducing agent released from the coupler had a high diffusivity. This effect was particularly noticeable in color reversal sensitive materials. For example, it has been known to use couplers that release development inhibitors (DIR couplers) for edge effects and interlayer effects. However, the current situation is that conventional DIR couplers cannot be used in color reversal sensitive materials because they do not have the effect of inhibiting development. This is because conventional -DIR couplers use a type of inhibitor that adsorbs to iron halide, and this is not effective in suppressing the phenomenon in color reversal processing where development activity is high.

However, the coupler of the present invention showed excellent graininess improvement effects and sharpness improvement effects even when used in color reversal sensitive materials. That is, in the second development of the color reversal process, the compound released from the coupler of the present invention functions as a scavenger for the oxidized developing agent and consumes the oxidized developing agent. As a result, the developable silver is consumed and color development is eventually suppressed, indicating the DIR effect.

Thiol or disulfide based compounds are preferred bleach accelerators. These bleach accelerators are particularly effective when bleach-fixing color light-sensitive materials for photography.

Examples of the fixing agent include thiosulfate, thiocyanate, thiourea thioether compounds, and a large amount of iodide, but thiosulfate is commonly used. As the preservative for the bleach-fix solution and the fix solution, sulfites, bisulfites, or carbonyl bisulfite adducts are preferred.

After bleach-fixing or fixing, washing with water is usually performed. In the water washing process, various known compounds may be added for the purpose of preventing precipitation and saving water. For example, to prevent precipitation, use water softeners such as inorganic phosphoric acid, aminopolycarboxylic acid, and organic phosphoric acid, fungicides and anti-spiking agents to prevent the growth of various bacteria, algae, and mold, magnesium salts, and aluminum. A hardening agent, typically salt, or a surfactant to prevent drying load and unevenness may be added as necessary. Orori, E, 'Wes
