Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a silver halide color photographic material in which the hue of magenta images is improved and the desilvering process is shortened.

(Prior art) In conventional color photographic compound light-sensitive materials,
A dye-forming coupler (hereinafter simply referred to as coupler) that produces yellow, magenta, and cyan dyes through a coupling reaction with an oxidized aromatic primary amine developing agent.
It is well known that color images are formed using . Among these, 5-pyrazolone coupler oil has been used for a long time as a magenta coupler. However, 5
- The azomethine dye produced by the coupling reaction between the birazolone coupler and the oxidized aromatic primary amine developing agent has a main absorption in the green light region and a secondary absorption in the blue light region, which is the color This was a problem in terms of color reproducibility of photographic materials. Therefore, in negative color light-sensitive materials, attempts have been made to improve color reproducibility by using an appropriate amount of a yellow-colored magenta coupler to substantially cancel out this side absorption. Although the use of such colored couplers is an effective and important technique for improving the color reproducibility of color photographic materials, on the other hand, it has the side effect of lowering the sensitivity of the photosensitive materials, which makes it difficult to use high-sensitivity photographic materials. This was one of the obstacles to the development of 1H-pyrazolo(1,5-b)-1, which was first developed in JP-A-59-171956,
It is known that 2,4-triazole is a magenta coupler skeleton that has no sub-absorption in the blue light region and has very excellent performance in terms of color reproduction. That is, if this 1H-pyrazolo[1,5-mutant)-1,2,4-)reazole can be used in a color negative photosensitive material, a photosensitive material with excellent color reproducibility can be produced without using a yellow-colored magenta coupler. It was considered possible to design

On the other hand, in recent years there has been a strong demand for faster processing of color negative light-sensitive materials. The processing process for color photosensitive materials can be roughly divided into the development process and the desilvering process, but the time required for the desilvering process is large compared to the processing time. Realization is essential.

As a method for increasing the bleaching edge, Research Disclosure+-Item Na No. 24241, No. 11449, and JP-A-61-201247 describe couplers that release bleach accelerator compounds. It is known that the use of silver halide color photographic materials containing couplers improves their desilvering properties.

(Problems to be Solved by the Invention) However, the bleach-accelerating compound-releasing coupler can be used with 1H-pyrazolo(1,5-b)-1,2゜4, a specific example of which is described in JP-A-59471956. -It was found that when used together with a triazole magenta coupler, the effect of improving desilvering properties becomes smaller. Also, JP-A-61-
No. 201247 includes an example of using the 1H-pyrazolo(5,1-c)-1,2,4-) riazole magenta coupler described in JP-A-58-42045 in combination with a bleach accelerator-releasing coupler. Although the effect is certainly recognized, the effect was insufficient when the desilvering process was accelerated. The present invention has been made to solve the above-mentioned problems of silver halide color photographic materials.

Accordingly, an object of the present invention is to provide a silver halide color photographic material that has excellent color reproducibility and rapid desilvering.

(Means for Solving the Problems) The above object of the present invention is to provide a silver halide color photographic light-sensitive material having at least one silver halide emulsion layer on a support. A compound that releases a bleach accelerator by reacting with an oxidized form of a developing agent, and at least one compound 1 represented by the following general formula [A]
It has been found that this can be achieved by a silver halide color photographic light-sensitive material characterized by containing H-pyrazolo[1,5-mutual)-1,2,4-)riazole magenta coupler.

General formula (A) -M formula (In Al, R+ represents an alkyl group, an alkoxy group, or an aryloxy group. When R1 is an alkyl group, R3 is a secondary alkyl group, a tertiary alkyl group, an aryl group, or a hetero Represents a ring group.

R3, R1 or X may form a dimer or more multimer. Nor does X represent a bleach accelerator or a precursor thereof.

Desilvering properties are achieved when the 1H-pyrazolo[1,5-mutual 3-1.2.4-) riazole magenta coupler described in JP-A-59-171956 and a bleach accelerator-releasing compound are used together. It was surprising that the improvement effect of 1H-pyrazolo[l,5-亙)-1,2,4
-) It is even more surprising that by changing the substituent directly attached to the mother nucleus of the lyazole magenta coupler as in the coupler of the present invention, the desilvering property was improved when used in combination with a bleach accelerator releasing compound. This effect is surprising.

(The following is a blank space) The light-sensitive material of the present invention only needs to have at least IN of the silver halide emulsion layers of a blue-sensitive layer, a green-sensitive layer, and a red-sensitive layer on the support, There are no particular restrictions on the number or order of the silver halide emulsion layers and non-light-sensitive layers.A typical example is to create multiple silver halide emulsion layers with substantially the same color sensitivity but different light sensitivities on the support. A silver halide photographic light-sensitive material having at least one light-sensitive layer consisting of a silver halide emulsion layer, the light-sensitive layer having unit photosensitivity that is sensitive to any one of blue light, green light, and red light. In multilayer silver halide color photographic light-sensitive materials,
Generally, the unit photosensitive layers are arranged in this order from the support side: a red sensitive layer, a green sensitive layer, and a blue sensitive layer. However, depending on the purpose, the above-mentioned order of installation may be reversed, or the order of installation may be such that different photosensitive layers are placed within the same color-sensitive layer.

Non-photosensitive layers such as various intermediate layers may be provided between the silver halide photosensitive layers and between the uppermost layer and the lowermost layer.

The intermediate layer includes JP-A Nos. 61-43748 and 59-1.

15. Development processing can be carried out by the usual methods described in the left column to right column.

The color developing solution used in the development of the light-sensitive material of the present invention is preferably an alkaline aqueous solution containing an aromatic primary amine color developing agent as a main component. Aminophenol compounds are also useful as color developing agents, but p-phenylenediamine compounds are preferably used, representative examples of which are 3-methyl-4-amino-N, N-diethylaniline, 3-methyl -4-amino-N-ethyl-N~
β-hydroxyethylaniline, 3-methyl-4-amino-N-ethyl-N-β-methanesulfonamidoethylaniline, 3-methyl-4-amino-N-ethyl-β-
Examples include methoxyethylaniline and their sulfates, hydrochlorides, p-toluenesulfonates, and the like. Two or more of these compounds can be used in combination depending on the purpose.

The color developer may contain pH 1 buffers such as alkali metal carbonates, borates or phosphates, development inhibitors such as bromide salts, iodide salts, benzimidazoles, benzothiazoles or mercapto compounds, or fogging agents. It generally contains an inhibitor. In addition, if necessary, hydroxylamine, diethylhydroxylamine, sulfite hydrazines, phenyl semicarbazides, triethanolamine, catechol sulfonic acid, )-lyethylenediamine (1,4-diazabicyclo(2,2,21

This black and white developer contains known black and white developing agents such as dihydroxybenzenes such as hydroquinone, 3-virapritones such as 1-phenyl-3-pyrazolidone, or aminophenols such as N-methyl-p-aminophenol. Alternatively, they can be used in combination.

The pH of these color developing solutions and black and white developing solutions is generally 9 to 12. The amount of replenishment of these developing solutions depends on the color photographic light-sensitive material to be processed, but -a is 32 or less per square meter of light-sensitive material, and by reducing the bromide ion concentration in the replenisher, 500
It can also be less than d. 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.

The time for color development processing is usually set between 2 and 5 minutes, but the processing time can be further shortened by using high temperature, high PL+, and high concentration of developing agent.

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

The bleaching process may be carried out simultaneously with the fixing process (bleach-fixing process) or 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 (■), Kobal) (I
Compounds of polyvalent metals such as [[), chromium (■), and copper ('It), peracids, quinones, nitro compounds, etc. are used.

Typical bleaching agents include ferricyanide; dichromate; organic complex salts of iron CT [1] or cobalt (In);

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 or forward flow, 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
Urnal of the 5ociety of M
tion Picture and Televisi
on Engineers Volume 64, P, 248-2
53 (May 1955 issue).

According to the multi-stage countercurrent method described in the above-mentioned literature, the amount of water used for washing can be significantly reduced, but due to the increase in the residence time of water in the tank, bacteria will breed, and the generated suspended matter will adhere to the photosensitive material. The problem arises. In the processing of color photosensitive materials of the present invention, as a solution to these problems,
The method for reducing calcium ions and magnesium ions described in JP-A No. 62-288,838 can be used very effectively. Also, JP-A-57-8.542

The pH of the washing water in the processing of the photosensitive material of the present invention is 4 to 4.
9, preferably 5-8. The washing water temperature and washing time can also be set variously depending on the characteristics of the photosensitive material, its use, etc., but generally it is 20 seconds to 10 minutes at 15 to 45°C, preferably 2
A range of 30 seconds to 5 minutes is selected at 5 to 40°C. Furthermore,

In such stabilization treatment, Japanese Patent Application Laid-Open No. 57-854
All known methods described in No. 3, No. 58-14834, and No. 60-220345 can be used.

Further, following the water washing treatment, a further stabilization treatment may be carried out, such as a stabilizing bath containing formalin and a surfactant, which is used as a final bath for color photosensitive materials for photography. .

Various chelating agents and antifungal agents can also be added to this stabilizing bath.

The overflow liquid from water washing and/or replenishment of the stabilizing liquid can be reused in other processes such as the desilvering process.

Samples 102-
114 was produced. These samples were processed to a size of 35+WIIl, a standard subject was photographed, and each was subjected to a running process of 500 m in the processing steps (1) and (It) shown below. Thereafter, samples 101 to 114 were subjected to wedge exposure of 20 CMS at 0 light, and developed in processing steps (1) and (n) using the processing solution after the running processing. The amount of residual silver in the sample was measured using fluorescent X-rays, and the results are shown in Table 1.

Table 1 shows that the samples of the present invention had a small amount of residual silver, and when used in combination with the I H-pyrazolo (1,5-b:l-1,2°4-triazole magenta coupler) of the present invention, the bleach accelerator-releasing coupler was found to work effectively.

Furthermore, it was found that this effect became even more pronounced in the running treatment of treatment step (II).

From these facts, it is clear that 1H-pyrazolo (1,5-
It has been found that by combining a b)-1,2,4-) lyazole magenta coupler and a bleach accelerator-releasing compound, a photographic material with excellent color reproducibility and rapid processing ability can be constructed. Ta.
