Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Field of Application) The present invention relates to a silver halide color photographic light-sensitive material.

(Prior Art) In silver halide color photographic materials, combinations of various light-sensitive silver halide emulsions and yellow couplers, cyan couplers and magenta couplers are usually used. Among these magenta couplers, pyrazoloazole couplers described in British Patent No. 1.252,418 and the like are preferable in terms of color reproduction because of their low side absorption of coloring dyes. However, when this coupler is used, it has a drawback that graininess deteriorates due to high coupling reactivity with oxidized color developer. In order to compensate for this drawback, U.S. Patent No. 3,227
, 554 is generally well known in the art. However, the azomethine dye produced by this method is unfavorable in terms of color reproduction of color images. Regarding this, colorless DIR couplers (for example, Japanese Patent Application Laid-open No. 49-77635
No. 50-20725) or dye-flow couplers (for example, Japanese Patent Application Laid-Open No. 168444-1982) have been proposed. Problems such as low coupling activity and significant contamination of the processing solution have not yet been solved. In addition, in order to eliminate the drawbacks of the above-mentioned functional couplers,

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 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 that is sensitive to blue light, green light, or red light, and in a multilayer silver halide color photographic light-sensitive material, generally the unit photosensitive layer is A red-sensitive layer, a green-sensitive layer, and a blue-sensitive layer are arranged in this order from the support side. However, depending on the purpose, the above-mentioned installation order may be reversed, or the installation order may be such that different color-sensitive layers are sandwiched between the same color-sensitive layers.

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.

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 West 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. In addition, JP-A-57

As described in No. 206541, No. 62-206543, etc., a low-sensitivity emulsion layer may be provided on the side far 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 (BH) / high sensitivity green sensitive layer (GH) / low sensitivity green sensitive layer (GL) / High-sensitivity red-sensitive layer (RH) / Low-sensitivity red-sensitive layer (RL), or BH/BL/GL/GH/RH/RL, or BH/BL/GH/GL/RL/RH They can be installed in the following order:

Further, as described in Japanese Patent Publication No. 55-34932, the blue-sensitive layer/G H/
They can also be arranged in the order of RH/GL/RL. Alternatively, as described in JP-A-56-25738 and JP-A-62-63936, the blue-sensitive layer/GL/RL/GH/RH can 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 a lower sensitivity, and the lower layer is a silver halide emulsion layer that 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 arranged and the photosensitivity decreases sequentially 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, 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. In addition, they may be arranged in the following order: high-sensitivity emulsion layer/low-sensitivity emulsion layer/middle-sensitivity emulsion layer or low-sensitivity emulsion N/middle-sensitivity emulsion layer/high-sensitivity emulsion layer.

Furthermore, even in the case of four or more layers, the arrangement may be changed as described above.

It can be measured by using a swellometer (swelling film) of the type described in No., pp. 124-129, and TI/□ is the maximum swelling film reached when treated with a color developer at 30°C for 3 minutes and 15 seconds. 90% of the thickness is defined as the saturation film thickness, and is defined as the time required to reach the film thickness of T I/f.

The film swelling rate TI, □ can be adjusted by adding a hardening agent to gelatin as a binder or by changing the aging conditions after coating. Further, the swelling rate is preferably 150 to 400%. The swelling ratio can be calculated from the maximum swollen film thickness under the conditions described above according to the formula = (maximum swollen film thickness - film thickness)/film thickness.

The color photographic material according to the present invention includes the above-mentioned RD, N

16, No. 651, 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 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, and I)-toluenesulfonates. Among these, 3-methyl-4-amino-N-ethyl-N-β-hydroxyethylaniline 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, benzimidazoles, benzothiazoles or mercapto compounds. If necessary, various preservatives such as hydroxylamine, diethylhydroxylamine, sulfites, hydrazines such as N,N-biscarboxymethylhydrazine, phenyl semicarbazides, triethanolamine, and catechol sulfonic acids, ethylene glycol, Organic solvents such as diethylene glycol, development accelerators such as benzyl alcohol, polyethylene glycol, quaternary ammonium salts, amines, dye-forming couplers, competitive couplers, auxiliary developing agents such as 1-phenyl-3-pyrazolidone, viscosity imparting agents. agent, aminopolycarboxylic acid, aminopolyphosphonic acid,
Various chelating agents such as alkylphosphonic acids and phosphonocarboxylic acids, such as ethylenediaminetetraacetic acid, nitrilotriacetic acid, diethylenetriaminepentaacetic acid, cyclohexanediaminetetraacetic acid, hydroxyethyliminodiacetic acid, 1-bitroxyethylidene-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. This can be cited as a representative example.

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 dihydroxybenzenes such as hydroquinone, 3-pyrazolidones such as 1-phenyl-3-pyrazolidone, or aminophenols such as N-methyl-p-aminephenol. 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 it is generally less than 30 m2 per square meter of light-sensitive material, and by reducing the bromide ion concentration in the replenisher,
It can also be set to 1 or less. When reducing the amount of replenishment, it is preferable to reduce the contact area with the air in the processing tank to prevent evaporation of the solution and air oxidation.The contact area between the photographic processing solution and the air in the processing tank is It 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.

Methods for reducing the aperture ratio in this manner include the method of using a movable lid as described in JP-A No. 1-82033, in addition to providing a shield such as a floating lid on the surface of the photographic processing solution in the processing tank;
The slit development method described in JP-A No. 63-216050 can be mentioned.

It is preferable to reduce the aperture ratio not only in both color development and black-and-white development steps, but also in all subsequent steps, such as bleaching, bleach-fixing, fixing, washing, 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.

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. As the bleaching agent, for example, compounds of polyvalent metals such as iron (III), peracids, quinones, nitro compounds, etc. are used. Typical bleaching agents include organic complex salts of iron (III), such as ethylenediaminetetraacetic acid, diethylenetriaminepentaacetic acid, cyclohexanediaminetetraacetic acid, methylimide, noniacetic acid, 1.3-diaminopropanetetraacetic acid, glycol ether diaminetetraacetic acid, etc. Aminopolycarboxylic acids or complex salts of citric acid, tartaric acid, malic acid, etc. can be used. Among these, aminopolycarboxylic acid iron(III) complex salts, including ethylenediaminetetraacetic acid iron(III) complex salt and 1,3-diaminopropanetetraacetic acid iron(III) complex salt, are preferable from the viewpoint of rapid processing and prevention of environmental pollution. . In addition, iron aminopolycarboxylate (Ill

West German Patent No. 1,290,812, JP-A-53-956
The compounds described in No. 30 are preferred.

Further 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 bleaching and fixing color light-sensitive materials for imaging.

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 (p k a ) of 2 to 5. Specifically, preferred compounds include acetic acid and propionic acid.

Examples of fixing agents used in fixing solutions and bleach-fixing solutions include thiosulfates, thiocyanates, thioether compounds, thioureas, and large amounts of iodide salts, but thiosulfates are commonly used. Among them, ammonium thiosulfate is the most widely used. It is also preferable to use a thiosulfate in combination with a thiocyanate, a thioether compound, thiourea, or the like. As a preservative for fixer and bleach-fixer,
Preferred are sulfites, bisulfites, carbonyl bisulfite adducts, and sulfinic acid compounds described in EP 294,769A.

Further, it is preferable to add various aminopolycarboxylic acids and organic phosphonic acids to the fixing solution and the bleach-fixing solution for the purpose of stabilizing the solution.

The total time of the desilvering process is preferably as short as possible without causing desilvering defects. The preferred time is 1 minute to 3 minutes, more preferably 1 minute to 2 minutes. In addition, the processing temperature is 25℃~
The temperature is 50°C, preferably 35°C to 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.

A specific method for strengthening stirring is described in Japanese Patent Application Laid-Open No. 1834-1983.
No. 60 and No. 62-183461, the method of impinging a jet of processing liquid on the emulsion surface of a photosensitive material, and the method of colliding a jet of processing liquid on the emulsion surface of a photosensitive material, as described in JP-A No. 62-183461,
No. 183461, 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. and 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 bleaching agent and fixing agent into the emulsion film, and as a result increases the desilvering rate.

The agitation improvement means described above are more effective when a bleach accelerator is used, and can significantly increase the accelerating effect and eliminate the fixing inhibiting effect of the bleach accelerator.

The automatic developing oven used for processing the photosensitive material of the present invention is disclosed in Japanese Patent Application Laid-open Nos. 60-191257 and 60-191258,
It is preferable to have a means for transporting a photosensitive material as described in Japanese Patent No. 60-191259. The above-mentioned Japanese Patent Application Laid-Open No. 60-191
As described in No. 257, such a conveyance means can significantly reduce the amount of processing liquid brought into the post bath from the front bath, and is highly effective in preventing performance deterioration 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 (the number of stages), the replenishment method such as countercurrent or forward flow, and various other conditions. Can be set over a wide range. this house,

ion Engineers Vol. 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-62-288838 can be used very effectively. In addition, isothiazolone compounds and thiabendazoles described in JP-A No. 57-8542,

It is also possible to use the fungicides described in 1986).

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 25 to 45°C.
A range of 30 seconds to 5 minutes at ~40°C is selected. moreover,
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 Nos. 57-8543 and 58-1483
All known methods described in No. 4 and No. 60-220345 can be used.

Further, following the water washing treatment, a further stabilization treatment may be performed. An example of this is a stabilization bath containing a dye stabilizer and a surfactant, which is used as a final bath for color photographic materials. be able to. Examples of the dye stabilizer include aldehydes such as formalin and glutaraldehyde, N-methylol compounds, hexamylenetetramine, and aldehyde sulfite adducts.

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. When each of the above-mentioned processing liquids is concentrated by evaporation in processing using an automatic processor or the like, it is preferable to correct the concentration by adding water.

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 a color developing agent, it is preferable to use various precursors of the color developing agent. For example, U.S. Patent No. 3,342,59

However, R.M.S.
The graininess indicated by the value worsens. Sample 103 to which DIR-hydroquinone was added, which should improve this defect, had the side effect of a decrease in sensitivity, although the graininess was slightly improved. Furthermore, in sample 104, there is a DIR in the layer adjacent to the GL layer.
- Addition of hydroquinone does not give satisfactory results. In contrast, the development inhibitor releasing compound 11-
It is clear that samples 105° and 107 using 3.II+-23 improve graininess without adversely affecting sensitivity and color haze.

In addition, an improvement trend was observed in the present invention samples 106 and 108 in which the development inhibitor releasing compound of the present invention was added to the layer adjacent to the GL layer, but no improvement effect was obtained when it was added to the GL layer. It can be seen that adding it to the same layer is better.
