Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a silver halide color photographic material, and more particularly to a silver halide color photographic material having excellent color reproducibility and processability.

(Prior Art) Color reproducibility is the most important characteristic in silver halide color photographic materials. In order to improve this color reproducibility, many efforts have been made to improve color reproducibility, including (1) optimizing spectral sensitivity, (2) optimizing interlayer effects, (3) reducing interlayer color mixture, and (4) optimizing color pigments. Technology is being developed. The present inventor has conducted intensive research mainly from the viewpoint of the multilayer effect of (2), and has improved color reproducibility by incorporating compounds of general formulas (1a) and (1b) into a silver halide color photographic material. I discovered that.

However, it has also been found that when this compound is used to the extent that a sufficient effect can be obtained, the desilvering properties deteriorate in the development process. In particular, in treatments where the bleaching step and the fixing step are performed in one bath, the desilvering ability is relatively small, so there is a need for improvement.

In order to improve the desilvering properties, it is known to add various desilvering accelerators to the sensitive material.

(Problem to be solved by the invention) However, when these compounds are included in a photosensitive material,
This had the disadvantage of deterioration in stability over time, especially an increase in fog.

Furthermore, it is also known that compounds adsorbed to silver halide grains in the light-sensitive material have a large effect on desilvering properties.

However, even with the above techniques, it cannot be said to be sufficient, and there has been a desire to develop further improved techniques.

Therefore, an object of the present invention is to provide a silver halide color photographic material having excellent color reproducibility and desilvering property.

NQ, 17643, pages 28-29, and No. l
Development processing can be carried out by the usual methods described in 651 left column to right column of 8716.

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-phenylenecyamine compounds are preferably used, representative examples of which include 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
-methoxyethylaniline and their sulfates, hydrochlorides, p-toluenesulfonates, and the like.

Among these, 3-methyl-4-amino-N-ethyl-N-β-hydroquinoethylaniline sulfate is particularly preferred.

Two or more of these compounds can be used in combination depending on the purpose.

The color developer may contain pH buffering agents such as alkali metal carbonates, borates or phosphates, chloride salts, bromide salts,
It is common to include development inhibitors or antifoggants such as iodide salts, hengimidazoles, benzothiazoles or mercapto compounds. If necessary, various preservatives such as hydroquinolamine, diethylhydroxylamine, sulfites, hydrazines such as N,N-biscarboquinomethylhydracine, phenyl semicarpant, triethanolamine, and catechol sulfonic acids may be added. constant agents, organic solvents such as ethylene glycol and diethylene glycol, development accelerators such as pencil alcohol, polyethylene glycol, quaternary ammonium salts, amines, dye-forming couplers, competitive couplers, 1-
Auxiliary developing agents such as phenyl-3-pyrazolidone, viscosity-imparting agents, various calcinants such as aminopolycarboxylic acids, aminopolyphosphonic acids, alkylphosphonic acids, and phosphonocarboxylic acids, such as ethylenecyamine. Tetraacetic acid, nitrilotriacetic acid, diethylenetriaminepentaacetic acid, noclohexaneaminetetraacetic acid, hydroxyethyliminodiacetic acid, 1-hydroxyethylidene-1,1-diphosphonic acid, nitrilo-N, N, N-trimethylenephosphonic acid, ethylenediamine -N, N, N, N-
Tetramethylenephosphonic acid, ethylene glycol (0-
Hydroxyphenylacetic acid) and their salts can be used in combination.

Further, when performing reversal processing, black and white development is usually performed and then color development is performed. This black and white developer contains known black and white developing agents such as dihydroquine benzenes such as hydroquinone, 3-pyrazolidones such as ■-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 being processed, but in general it is 31 or less per square meter of light-sensitive material, and by reducing the bromide ion concentration in the replenisher, it can be increased to 500 or less.
It can also be less than m1. 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.

The contact area between the photographic processing solution and air in the processing tank can be expressed by the aperture ratio defined below.

That is, the above aperture ratio is preferably 0.1 or less, more preferably 0.001 to 0.05. As a method for reducing the aperture ratio in this way, in addition to providing a shield such as a floating lid on the surface of the photographic processing liquid in the processing tank,
Method using a movable lid described in No. 033, JP-A-63
The slit development processing method described in Japanese Patent No. 216050 can be mentioned. Reducing the aperture ratio is important not only for both color development and black and white development processes, but also for subsequent processes,
For example, it is preferable to apply it to all steps such as bleaching, bleach-fixing, fixing, washing with water, and stabilization. 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 pH, and high concentration of color developing agent.

In the color reversal development method, reversal processing is performed after black and white development.
This reversal bath will be explained.

The reversal bath can contain a known fogging agent. That is, stannous ion-organophosphate complex salt (U.S. Pat. No. 3,
617,282), stannous ion organic phosphonocarboxylic acid complex salt (Japanese Patent Publication No. 56-32616),
stannous ion complex salts such as stannous ion-aminopolycarboxylic acid complex salts (UK Patent No. 1,209.050), borohydride compounds (US Pat. No. 2,984°567), heterocycles boron compounds such as amine borane compounds (UK Patent No. 1,011,000); The pH of this fogging bath (inversion bath) ranges widely from the acidic side to the alkaline side.
2-12, preferably 2.5-1O1, particularly preferably 3
It is in the range of ~9. In place of the reversal bath, a light reversal process may be performed by re-exposure, and the reversal step can also be omitted by adding the above-mentioned fogging agent to the color developing solution.

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. The present invention is more effective and preferable when performing this bleach-fixing treatment. Furthermore, in order to speed up the processing, a processing method may be used in which bleaching is followed by bleach-fixing. Furthermore, depending on the purpose, treatment may be carried out in two consecutive bleach-fixing baths, fixing treatment before bleach-fixing treatment, or bleaching treatment after bleach-fixing treatment. As a bleaching agent, for example, iron (
polyvalent metal compounds such as III), peracids, quinones,
Nitro compounds and the like are used. Typical bleaching agents include organic M salts of iron (Ill) such as ethylenediaminetetraacetic acid, diethylenetriaminepentaacetic acid, cyclohexanediaminetetraacetic acid, methyliminodiacetic acid, 1. Aminopolycarboxylic acids such as 3-diaminopropanetetraacetic acid and glycol ether diaminetetraacetic acid, or complex salts such as citric acid, tartaric acid, and malic acid can be used. Among these, aminopolycarboxylic acid iron(III) complex salts, including ethylenediaminetetraacetic acid iron(III) complex salt and l,3-diaminopropanetetraacetic acid iron(III) complex salt, 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 4.0 to 8, or it can be processed at an even lower pH to speed up the processing. .

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.

No. 8, West German Patent No. 1,290.812, Japanese Unexamined Patent Publication No. 1983-
Preference is given to the compounds described in No. 95.630. Also preferred are the compounds described in US Pat. No. 4,552,834. These bleach accelerators may be added to the photosensitive material. These bleach accelerators are particularly effective when bleach-fixing color photographic materials.

In addition to the above-mentioned compounds, the bleaching solution and bleach-fixing solution preferably contain an organic acid for the purpose of preventing bleach staining. Particularly preferred organic acids have an acid dissociation constant (pKa) of
-5, specifically acetic acid, propionic acid, etc. are preferred.

Examples of fixing agents used in fixing solutions and bleach-fixing solutions include thiosulfates, thiocyanates, thioether compounds, thioureas, and large amounts of iodide salts. Among them, ammonium thiosulfate is the most widely used. Further, a combination of thiosulfate, thiocyanate, thioether compound, thiourea, etc. is also preferred. As the preservative for the fixer and bleach-fixer, sulfites, bisulfites, carbonyl bisulfite adducts, or sulfinic acid compounds described in European Patent No. 294,769A are preferred. Furthermore, it is preferable to add various aminopolycarboxylic acids and organic phosphonic acids to the fixing solution and bleach-fixing solution for the purpose of stabilizing the solution. The total time for the desilvering process is
It is preferable that the length be as short as possible so long as desilvering failure does not occur. The preferred time is 1 minute to 3 minutes, more preferably 1 minute to 2 minutes.

Furthermore, the treatment temperature is 25°C to 50°C, preferably 35°C to
The temperature is 45°C. In a preferred temperature range, the desilvering rate is improved and the occurrence of staining after processing is effectively prevented.

In the desilvering step, it is preferable that stirring be as strong as possible. Specific methods for strengthening the agitation include the method of impinging a jet of processing liquid on the emulsion surface of the photosensitive material described in JP-A-62-183460, and the method described in JP-A-62-183.
No. 461, a method of increasing the stirring effect using a rotating means, and further improving the stirring effect by moving the photosensitive material while bringing the emulsion surface into contact with a wiper blade provided in the liquid to create turbulence on the emulsion surface. Examples include a method of increasing the circulation flow rate of the entire treatment liquid. Such means for improving agitation is effective for all bleaching solutions, bleach-fixing solutions, and fixing solutions. It is believed that improved stirring speeds up the supply of bleach and fixing agent into the emulsion film, and as a result increases the desilvering rate. Further, the agitation improving means described above is more effective when a bleach accelerator is used, and can significantly increase the accelerating effect and eliminate the fixing inhibiting effect caused by the bleach accelerator.

The automatic developing machine used for the photosensitive material of the present invention is
No. 0-191257, No. 60-191258, No. 60
It is preferable to have the photosensitive material conveying means described in Japanese Patent Application No. 191259. As described in the above-mentioned Japanese Patent Application Laid-Open No. 60-191257, such a conveying means can significantly reduce the carry-over of the processing liquid from the front bath to the rear bath, and is highly effective in preventing deterioration of the performance of the processing liquid. Such effects are particularly effective in shortening the processing time in each step and reducing the amount of processing liquid replenishment.

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
urnalof the 5ociety of M
tion Picture and Televis
Jon 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 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 JP-A No. 62-288.838 can be used very effectively. Also, JP-A-57-8,542

The results are shown in Table 2. The smaller this value is, the less residual silver there is, indicating that the degree of desilvering failure is smaller.

Next, two samples each were taken from Samples 101 to 113, and one sample was subjected to wedge exposure using white light, and the other sample was subjected to wedge exposure using a green light source. These samples were subjected to a bleach-fixing time of 120' in the above treatment.

After processing, sensitometry was performed on the magenta image of the sample, and the sensitivity ratio between the magenta image of the white-exposed sample and the magenta image of the green-exposed sample was determined for each sample. The results are also shown in Table 2. This indicates the degree of the interlayer effect on the green-sensitive emulsion layer, and the larger the value, the greater the interlayer effect, which is preferable in terms of color reproduction.

As seen from Table 2, the sample Nα1 according to the present invention
It can be seen that 06 to 109.111.113 have improved desilvering properties, a large multilayer effect, and are preferable in terms of color reproduction.

I(w+x+y+z=20) After the treatment, the amount of silver remaining in the sample was determined by optical density measurement using yellow light. The results are shown in Table 6. The smaller this value, the less residual silver and the smaller the degree of desilvering failure.

Next, two samples from each of samples 201 to 213 were taken, and one sample was subjected to wedge exposure using white light, and the other was subjected to wedge exposure using a green light source. These samples were subjected to the above-mentioned treatment using a fixing time of 4 minutes.

After processing, sensitometry was performed on the magenta image of the sample, and the sensitivity ratio between the magenta image of the white exposed sample and the magenta image of the green exposed sample was determined for each sample. The results are also shown in Table 6. This indicates the degree of interlayer effect on the green-sensitive emulsion layer, and the larger this value is, the greater the interlayer effect is, which is preferable in terms of color reproduction.

As seen from Table 6, sample No. 206 according to the present invention
It can be seen that samples 213 to 213 have improved desilvering properties, a large multilayer effect, and are preferable in terms of color reproduction.
