Description

Detailed Description of the Invention (Industrial Application Field) The present invention relates to a silver halide color photographic light-sensitive material, and more specifically, a naphthol cyan coupler having a substituent at the 5-position and an alkoxy group or an aryloxy group at the 6-position. The present invention relates to a silver halide color photographic light-sensitive material containing a pyrazoloazole magenta coupler having a pyrazoloazole group.

(Prior Art) Silver halide color light-sensitive materials preferably have good color development, color reproducibility, and sharpness, as well as good processing dependence, stability over time, and color image storage. A naphthol-based cyan coupler that relatively satisfies the above performance has been proposed in European Patent No. 161,626A, and a magenta coupler has been proposed in U.S. Patent No. 4,540,654 and European Patent No. 226849A. The effect was small when used.

Therefore, some combinations of these were proposed in JP-A-62-180365, which certainly improves color reproducibility, processing dependence,
Image storage has been improved. However, it has become clear that there is a problem in that the photographic performance of silver halide photosensitive materials changes during storage over time.

(Problems to be Solved by the Invention) An object of the present invention is to provide a photosensitive material that simultaneously satisfies the above-mentioned performances required of a color photosensitive material. More specifically, the purpose of the present invention is, firstly, to provide a color sensitive material with excellent color reproducibility, and secondly, to provide a color sensitive material with excellent color reproducibility. The purpose of the present invention is to provide a color photosensitive material with little change in performance during image storage.The third objective is to provide a color photosensitive material with excellent image storage properties.
Fourthly, the objective is to provide a color sensitive material with little change in density after processing even in degraded or low pH bleach and bleach-fix baths.Fifthly, the objective is to provide a color sensitive material with high sensitivity and excellent sharpness. Our goal is to provide the following.

(Means for Solving the Problems) The above problems are caused by a red-sensitive silver halide emulsion layer containing a cyan coupler, a green-sensitive silver halide emulsion layer containing a magenta coupler, and a yellow coupler containing a red-sensitive silver halide emulsion layer containing a yellow coupler on a support.

This black and white developer contains known black and white developing agents such as dihydroxybenzenes such as hydroquinone, 3-pyrazolidones 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 it is generally less than 31 per square meter of the light-sensitive material, and by reducing the bromide ion concentration in the replenisher, it can be increased to 500
It can also be lower than mA. 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 performed simultaneously with the fixing process (bleach-fixing process), or may be performed separately. Furthermore, in order to speed up the processing, a processing method may be used in which a bleaching treatment is followed by a bleach-fixing treatment. 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 (■), cobalt (I [
Compounds of polyvalent metals such as I), chromium (■), and copper (II), peracids, quinones, and nitro compounds are used.

Typical bleaching agents include ferricyanide; dichromate; organic complex salts of iron (III) or cobalt (III), such as ethylenediaminetetraacetic acid, diethylenetriaminepentaacetic acid, cyclohexanediaminetetraacetic acid, methyliminodiacetic acid, and 1,3-diaminoacetic acid. Aminopolycarboxylic acids such as propanetetraacetic acid, glycol ether diamine tetraacetic 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 (I[+) complex salts and persulfates, including iron ethylenediaminetetraacetate (I[[> If salt), are preferable from the viewpoint of rapid processing and prevention of environmental pollution. Iron(III) complex salts are particularly useful in both bleaching solutions and bleach-fixing solutions.The pH of bleaching solutions or bleach-fixing solutions using these aminopolycarboxylic acid iron(Iff) complexes is usually 5.5 to 8. However, to speed up the process, it is also possible to process at an even lower pH.

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.

Also preferred are the compounds described in No. 2.834. These bleach accelerators may be added to the photosensitive material. These bleach accelerators are particularly effective when bleach-fixing color light-sensitive materials for photography.

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

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 washing water 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 washing water temperature, 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

You can ask for it.

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 propagate and the generated suspended matter will adhere to the photosensitive material. The problem arises. In the processing of the color photosensitive material of the present invention, as a solution to such problems,
The method for reducing calcium ions and magnesium ions described in Japanese Patent Application No. 61-131.632 can be used very effectively. Also, patent application No. 57-8.542

The pH of the washing water in the processing of the photosensitive material of the present invention is 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 - 10 minutes at 15-45°C, preferably 20 minutes.
A range of 30 seconds to 5 minutes at 5-40°C is selected. Furthermore,

All known methods described in No. 34 and No. 60-220,345 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.
