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) Conventional color photographic materials use dye-forming couplers (hereinafter simply referred to as couplers) that produce yellow, magenta, and cyan dyes through a coupling reaction with an oxidized aromatic primary amine developing agent. ) is known to be used to form color images.

Among these, 5-pyrazolone couplers have been used for a long time as magenta couplers. However, 5-
The azomethine dye produced by the coupling reaction between the pyrazolone 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. There was a problem with the color reproducibility of the material. Therefore, in order to solve this hue problem, LH-pyrazolo [5°1- and 1,2,4-) riazole (1
Magenta couplers (also referred to as H-pyrazolo[3,2-mutual)-3-)riazole] have recently begun to be put to practical use in negative color light-sensitive materials.

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 broadly divided into the development process and the desilvering process, but the time required for the desilvering process is large compared to the processing time, and in order to speed up the processing, it is necessary to speed up the desilvering process. Required.

As a method for increasing the bleaching edge, Research Disclosure+-Item No. 24241, No. 11449 and JP-A-61-201247 describe bleach-accelerating compound-releasing couplers; It is known that the use of silver halide color photographic materials containing couplers improves their desilvering properties. JP-A-61-201247 discloses desilvering accelerator-releasing couplers and 1H-pyrazolo[5,1-
An example is described in which a 1,2,4-1-riazole magenta coupler is used in combination with the 1,2,4-1-riazole magenta coupler.

(Problems to be Solved by the Invention) However, the desilvering accelerator releasing coupler described in JP-A-61-201247 and 1H-pyrazolo[5,1-c]
Although the desilvering promoting effect is certainly observed in photosensitive materials using -1,2,4-triazole magenta couplers in combination, it is still insufficient, especially when developing in a rapid processing step using a bleach-fixing bath. It was observed that silver failure occurred. Furthermore, it has been found that staining occurs when this photosensitive material is processed by anhydrous washing using a stabilizing bath and is stored under high humidity conditions. It has also been found that this photosensitive material does not have sufficient sharpness of color images, which is one of the particularly important properties in color negative photosensitive materials. The present invention has been made to solve the above-mentioned problems of silver halide color photographic materials.

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

A second object of the present invention is to provide a silver halide color photographic material in which image sharpness is improved by thinning the layer.

A third object of the present invention is to provide a silver halide color photographic material that exhibits less staining during long-term storage after processing.

A fourth object of the present invention is to provide a silver halide color photographic material that exhibits good desilvering properties even during running processing using a bleach-fixing bath.

A fifth object of the present invention is to provide a silver halide color photographic light-sensitive material in which cyan coupler does not suffer from defective color recovery even during running processing using a bleach-fixing bath.

Further, the magenta coupler represented by the general formula (A) of the present invention can be used in combination with other types of magenta couplers.

Next, the silver halide color photographic material used in the present invention will be explained.

The light-sensitive material of the present invention only needs to have at least one silver halide emulsion layer of a blue-sensitive layer, a green-sensitive layer, and a red-sensitive layer on the support. There are no particular limitations on the number and order of the emulsion layers and non-photosensitive layers. A typical example is a silver halide photographic light-sensitive material having on a support at least one photosensitive layer consisting of a plurality of silver halide emulsion layers having substantially the same color sensitivity but different photosensitivity. The photosensitive layer is a unit photosensitive layer sensitive to blue light, green light, or red light, and in the multilayer silver halide color photographic light-sensitive material,
Generally, the unit photosensitive layers are arranged in this order from the support side: a red color sensitive layer, a green color sensitive layer, and a blue color 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 halogenated photosensitive layers and between the uppermost layer and the lowermost layer.

The intermediate layer includes JP-A Nos. 61-43748 and 59-1.
No. 13438, No. 59-113440, No. 61-20
Coupler, DIR compound, etc. as described in No. 037 and No. 61-20038 may be included,
It may also contain a commonly used color mixing inhibitor.

A plurality of silver halide emulsion layers constituting each unit photosensitive layer are composed of a high-speed emulsion layer and a low-speed emulsion layer, as described in German Patent No. 1.121,470 or British Patent No. 923.045. A two-layer configuration can be preferably used.

Usually, it is preferable to arrange the layers so that the photosensitivity decreases toward the support, and a non-photosensitive layer may be provided between each halogen emulsion layer. Also, JP-A-57-
No. 112751, No. 62-200350, No. 62-2
As described in Nos. 06541 and 62-206543, a low-density emulsion layer may be provided on the side away from the support, and a high-sensitivity emulsion layer may be provided on the side close to the support.

As a specific example, from the side farthest from the support, low sensitivity blue sensitive layer (BL) / high sensitivity blue sensitive layer N (Bll) / high sensitivity green sensitive layer (NiH) / low sensitivity green sensitive layer (GL )/
High-sensitivity red-sensitive layer (R11) /low-sensitivity red-sensitive layer (R
L) or Bll/BL/GL/GH/RH/R
In order of L or 88/BL/GH/GL/RL/R11
They can be installed in the following order:

Furthermore, as described in Japanese Patent Publication No. 55-34932, blue-sensitive N/GH/R
They can also be arranged in the order of H/GL/RL. Alternatively, as described in JP-A-56-25738 and JP-A-62-63936, the blue-sensitive layer/GL/RL/Gll/RH may be arranged in this order from the farthest side from the support. .

In addition, as described in Japanese Patent Publication No. 49-15495, the upper layer is a silver halide emulsion layer with the highest sensitivity, the middle layer is a silver halide emulsion layer with lower sensitivity, and the lower layer is more sensitive than the middle layer. An example is an arrangement consisting of three layers with different photosensitivity, in which a silver halide emulsion layer with a low density is disposed and the photosensitivity gradually decreases toward the support. Even when it is composed of three layers with different photosensitivity, as described in JP-A No. 59-202464,
In the same color-sensitive layer, the medium-sensitivity emulsion layer/high-sensitivity emulsion layer/low-sensitivity emulsion layer may be arranged in this order from the side remote from the support.

As mentioned above, various layer structures and arrangements can be selected depending on the purpose of each photosensitive material.

The preferred silver halide contained in the photographic emulsion layer of the photographic light-sensitive material used in the present invention is silver iodobromide, silver iodochloride, or silver iodochlorobromide, which contains about 30 mol% or less of silver iodide. be. Particularly preferred is silver iodobromide or silver iodochlorobromide containing from about 2 mole percent to about 25 mole percent silver iodide.

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-

The color developer may contain pH buffering agents such as alkali metal carbonates, borates or phosphates, bromide salts, iodide salts,
Development inhibitors or anticapri agents such as benzimidazoles, benzothiazoles or mercapto compounds are generally included. In addition, as necessary, various compounds such as hydroxylamine, diethylhydroxylamine, sulfite hydrazines, phenyl semicarbazides, triethanolamine, catechol sulfonic acids, and triethylenediamine (l,4-diazabicyclo(2,2,21 octane)) may be added. preservatives, organic solvents such as ethylene glycol, diethylene glycol, development accelerators such as benzyl alcohol, polyethylene glycol, quaternary ammonium salts, amines, dye-forming couplers, competitive couplers, caplacing agents such as sodium boron hydride, Auxiliary developing agents such as 1-phenyl-3-pyrazolidone, viscosity imparting agents, various chelating agents such as aminopolycarboxylic acids, aminopolyphosphonic acids, alkylphosphonic acids, and phosphonocarboxylic acids, e.g. , ethylenediaminetetraacetic acid, nitrilotriacetic acid, diethylenetriaminepentaacetic acid, cyclohexanediaminetetraacetic acid, hydroxyethyliminodiacetic acid, 1-hydroxyethylidene-
1,1-diphosphonic acid, nitrilo-N,N,N-trimethylenephosphonic acid, ethylenediamine-N,N,N,N

Known black and white developing agents such as 3-pyrazolidones such as 1-phenyl-3-pyrazolidone or aminophenols such as N-methyl-p-aminophenol can be used alone or 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 is generally 32 or less per square meter of light-sensitive material, and by reducing the bromide ion concentration in the replenisher, 500
−Can also be less than or equal to: 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 pt+, and high concentration of color 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 (n), peracids, quinones, nitro compounds, etc. are used.

Typical bleaching agents include ferricyanide; dichromate; organic complex salts of iron (III) or cobalt (I), such as ethylenediaminetetraacetic acid, diethylenetriaminepentaacetic acid, cyclohexanediaminetetraacetic acid, methyliminodiacetic acid, 1.3 - Aminopolycarbonate M such as diaminopropanetetraacetic acid, glycol ether diaminetetraacetic acid, or complex salts of citric acid, tartaric acid, malic acid, etc.;
Persulfates; bromates; permanganates; nitrobenzenes and the like can be used. Among these, aminopolycarboxylic acid iron (III) complex salts and persulfates, including ethylenediaminetetraacetic acid iron (I [[) complex salts] are preferred from the viewpoint of rapid processing and prevention of environmental pollution. Furthermore, aminopolycarboxylic acid iron(1) complex salts are particularly useful in both bleach and bleach-fix solutions. The pH of the bleach solution or bleach-fix solution using these aminopolycarboxylic acid iron(III) complex salts is usually 5.5 to 8, but in order to speed up the processing, it can be processed at an even lower pi+. .

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

Specific examples of useful bleach accelerators are described in U.S. Pat. No. 3,893.858, German Pat.

These bleach accelerators may be added to the bleaching material. These bleach accelerators are particularly effective when bleach-fixing color light-sensitive materials for photography.

Examples of fixing agents include thiosulfates, thiocyanates, 1,000-onythyl compounds, thioureas, and large amounts of iodide salts, but thiosulfates are commonly used, with ammonium thiosulfate being the most commonly used. Can be used widely. As the preservative for the bleach-fix solution, sulfites, bisulfites, or carbonyl bisulfite adducts are preferred.

It is preferable that the silver halide color photographic light-sensitive material of the present invention undergoes a water washing and/or stabilization step after the 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 30 seconds to 5 minutes at 25 to 40°C. A range is selected. Furthermore, the photosensitive material of the present invention can also be directly processed with a stabilizing solution instead of washing with water.

In such stabilization treatment, Japanese Patent Application Laid-Open No. 57-854
All known methods described in No. 3, No. 5B-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.

The silver halide color light-sensitive material of the present invention may contain a color developing agent for the purpose of simplifying and speeding up processing. In order to incorporate the color developing agent, it is preferable to use various precursors of the color developing agent. For example, U.S. Patent No. 3.342.59

Example 2 The sharpness of the green sensitive layer of the samples obtained by developing Samples 101 to 112 in the processing step (n) was evaluated using a conventional MTF value. The results are shown in Table 2.

From Table 2, it was found that the brightening material using the magenta coupler of the present invention having a molecular weight of 620 or less gave a good MTF value indicating sharpness.

Example 3 Next, samples 101 to 112 were exposed to white light for 20CM in the same manner as before.
S wedge exposure was performed, and development processing was performed in processing step (III). The residual ophthalmic measurements of these samples are shown in Table 3. Furthermore, these samples were incubated at 80°C and 170% for 2
After storage for a week, the B density of the unexposed area was measured, and the increment relative to the sample before storage is shown in Table 3.
