Description

Detailed Description of the Invention (Field of Industrial Application) The present invention relates to a silver halide color photographic light-sensitive material, in particular a silver halide color photographic material that is processed using a bleaching cabinet or a bleach-fix solution that is tired or has weak oxidizing power. This invention also relates to a silver 9-10-genide color photographic light-sensitive material that does not cause a decrease in color density, has excellent image storage stability, and has thinner layers and improved image quality.

(Prior art) When a silver halide photographic light-sensitive material is exposed to light and then subjected to color development, an oxidized aromatic primary amine developing agent reacts with a dye-forming coupler (hereinafter referred to as coupler), resulting in color development. An image is formed.

Couplers and coloring dyes for color photographic materials are required to have various performances. For example, it has excellent stability, excellent processing suitability, excellent hue of the dye image, and fastness of the dye image.

Conventionally, phenolic couplers and naphthol couplers have been used as shear couplers.

In particular, for 2-alkylcarbamoyl-7-naphthol couplers, the maximum absorption (λmax) of the coloring dye produced is long wavelength, with little side absorption in the edge region, and many couplers with excellent coloring properties have been found, and they can be manufactured at low cost. It has excellent suitability and has been widely used as a color negative photosensitive material.

However, these couplers have the disadvantage that sufficient color images cannot be obtained if the bleaching or bleach-fixing solution is tired or has weak oxidizing power during the bleaching or bleach-fixing process of color development processing. However, the cyan image formed by the coupler has a further drawback of low fastness.

In contrast, U.S. Pat. It was also disclosed that the fastness of the dye image was excellent.

These improvements were remarkable, but due to variations in hue due to color density, and the crystallinity of couplers and generated dyes, which tend to precipitate, it was necessary to reduce the amount of high-boiling organic solvents incorporated into light-sensitive materials. Therefore, it has disadvantages such as difficulty in thinning the layer.

On the other hand, U.S. Patent No. 3,1111. /? J issue, Japanese Patent Application Publication No. 1973-
No. 23714171, same t/-/ltj! No. 17, same 4
The 2-arylcarbamoyl-l-naphthol coupler described in /-/j34←No. The amount of high-boiling organic solvent required to disperse the coupler can be reduced and the layer can be made thinner. However, they had drawbacks such as poor optical staining, long-wave color sum, and decreased color development during refrigerated storage.

In addition, in Japanese Patent Application Kokai Sho≦J-yrtti, λ,j-diacylaminophenol having a specific ballast at the 5th position suppresses the aforementioned decrease in color density and deterioration of color image fastness, and reduces the amount of high-boiling organic solvent. It is disclosed that thinning is possible. However, it has slightly poor fading properties and a short-wave hue, and although it is used in positive photosensitive materials, its use in negative photosensitive materials for photography has not been considered.

(Problems to be Solved by the Invention) Objectives of the Invention Vi Firstly, a silver halide color photograph that does not reduce cyan coloring density even when processed using a bleach or bleach-fix solution that is tired or has weak oxidizing power. Our purpose is to provide photosensitive materials.

A second object of the present invention is to provide a silver halide color photographic material with excellent cyan image fastness.

A third object of the present invention is to provide a silver halide color photographic material with excellent image quality.

A fourth object of the present invention is to provide a silver halide color photographic material in which the coloring performance of color couplers is improved.

(Means for Solving the Problems) As a result of extensive studies, the present inventors found that Silver Halide Power 2, which has one or more red-sensitive emulsion layers, one or more green-sensitive emulsion layers, and one or more blue-sensitive emulsion layers on a support, respectively. - At least one cyan dye-forming coupler selected from the following -Formation [:I)> and -Formation (If) in the photographic light-sensitive material and at least one cyan dye-forming coupler represented by the following -Formation (III) One color developing agent, a compound that reacts with the oxidized form of the color developing agent to release a diffusible development inhibitor or its precursor, and another 7 molecules of a compound that is cleaved after reacting with the oxidized form of the color developing agent. It has been found that the object of the present invention is distantly related to the object of the present invention by a silver halide color photographic light-sensitive material containing at least one compound selected from compounds that cleave a development inhibitor by reacting with an oxidant.

The layer to which each cyan coupler is added is mainly a red-sensitive layer, but it can be optionally added to other photosensitive layers or non-photosensitive layers depending on the purpose.

- At least one kind of cyan coupler among Monna CIO> and [■] and at least one kind of cyan coupler of the general formula (Iff) may be used by being added to the same layer or different layers of the photosensitive material.

Usually, when a hecoupler is incorporated into a silver halide sensitive material, it is dissolved in a high-boiling organic solvent and dispersed as minute oil droplets in a hydrophilic medium. Color development, storage stability, and color image fastness are often influenced by the ratio between the amount of the high-boiling organic solvent and the amount of coupler. Usually, the greater the amount of the high-boiling organic solvent, the higher the color development. The film thickness of the material increases and the sharpness deteriorates.

The shea couplers of the general formulas CI) to (III) of the present invention are couplers that can be made into thin layers with little deterioration in color development even if the amount of the core high-boiling organic solvent is reduced. The weight ratio of the high-boiling organic solvent and the coupler contained in the same layer is preferably less than 0, preferably less than 1.0, more preferably less than 0.2, and most preferably less than 1.
This is the case where O is used and no high boiling point organic solvent is used.

The diffusive development inhibitor-releasing compound used in the present invention can be added to either the silver halide emulsion layer or the non-photosensitive intermediate layer in the silver halide color photographic light-sensitive material.

When a silver halide emulsion is included in the same layer, the amount of the diffusible development inhibitor-releasing compound added is in the range of o.oooi to 0.1 mole per mole of silver in the same layer, preferably 1 mole. θ, in the range of '00/-0,0j mol, more preferably 0
．． The range is from 00j to 0,000 oz moles. When the same layer does not contain a silver halide emulsion, it can be used in an amount within the above-mentioned range per mole of silver contained in the adjacent photosensitive layer.

Development inhibitor-releasing compounds can be broadly classified into diffusible development inhibitor-releasing compounds and non-diffusible development inhibitor-releasing compounds, depending on the degree of diffusion of the development inhibitor. The development inhibitor releasing compounds may be used alone or in combination of four or more types having different degrees of diffusivity.

When used in combination, they may be used together in the same layer, each may be used alone in different layers of the same color-sensitive layer, or each may be used alone in different layers of different color-sensitive layers. May be used in

When the color-sensitive layer is composed of a fast layer and a slow layer, the development inhibitor releasing compound may be used in an offset layer. Diffusible development inhibitor releasing compounds can be preferably used in the slow speed layer.

When the color sensitive layer is comprised of fast and medium speed layers and a slow speed layer, the development inhibitor releasing compound may be used in either layer. Diffusible development inhibitor releasing compounds can preferably be used in the medium speed layer and/or the slow speed layer.

The development inhibitor-releasing compound can be a timed development inhibitor-releasing compound that releases the development inhibitor via a step of releasing a precursor by reaction with an oxidized developing agent, or can be developed directly by reaction with an oxidized developing agent. It is classified as a non-timed development inhibitor-releasing compound that releases an inhibitor. The timing type development inhibitor releasing compound and the non-timing type development inhibitor releasing compound can be used alone or in combination of two or more types. When used in combination, they may be used together in the same layer, in different layers in the same color-sensitive layer, or in different layers in different color-sensitive layers.

It is more preferable to use a development inhibitor-releasing compound in which the released development inhibitor exhibits a development inhibitory effect in the photosensitive material, but quickly loses its development inhibitory ability when it flows out from the photosensitive material into the developer. commonly used.

The cyan coupler of the general formulas [I] to CIII) of the present invention and the diffusive development inhibitor releasing compound can be used in the same layer or in different layers in the sensitive material.

The light-sensitive material of the present invention only needs to have at least one silver halide emulsion layer each 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. As a typical example, a blue-sensitive, green-sensitive, and red-sensitive light-sensitive layer consisting of a plurality of silver halide emulsion layers having substantially the same color sensitivity but different light sensitivities is formed on a support. A silver halide photographic light-sensitive material having at least one unit photosensitive layer, generally arranged in order from the support side: a red-sensitive layer, a red-sensitive layer,
The green-sensitive layer is installed in that order, followed by the blue-sensitive layer.

However, depending on the purpose, the order of installation may be reversed, or the order of installation may be such that different photosensitive layers are sandwiched between the same color-sensitive layer.

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

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 in which a silver halide emulsion layer with a low density is arranged, and the photosensitivity is sequentially lowered toward the support, and the photosensitivity varies from 3N to tJI. Even in the case where the layer is composed of three layers with different photosensitivity, as described in JP-A No. 59-202464, medium-sensitivity emulsion is added from the side remote from the support in the same color-sensitive layer. They may be arranged in the following order: layer/high-speed emulsion layer/low-speed emulsion layer.

In addition, high-sensitivity emulsion layer / low-sensitivity emulsion layer / medium-sensitivity emulsion layer,
Alternatively, they may be arranged in the order of low-speed emulsion layer/medium-speed emulsion layer/high-speed emulsion layer, etc.

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

Various chelating agents such as alkylphosphonic acids and phosphonocarboxylic acids, such as ethylenecyagonatetraacetic acid, nitrilotriacetic acid, diethylenetriaminepentaacetic acid, cyclohexanediaminetetraacetic acid, hydroxyethyliminodiacetic acid, l-hydroxyethylidene -1,1-diphosphonic acid, nitrilo-N,N,N-)rimethylenephosphonic acid, ethylenediamine-N,N,N,N tetramethylenephosphonic acid, ethylenediamine di(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. In this black and white developer, known black and white developing agents such as dihydroxybenzenes such as hydroquinone, 3-birapritones such as -phenyl-3-pyrazolidone, or aminophenols such as N-methyl-p-aminophenol may be used alone or 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 31 or less per square meter of photosensitive material for -IC, and by reducing the bromide ion concentration in the replenisher, it can be reduced to 50.
It can also be set to 0- or less. 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. It is also possible to reduce the amount of replenishment by using means to mark the accumulation of bromide ions in the developer solution.

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 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 that can be used include compounds of polyvalent metals such as iron (III), peracids, quinones, nitro compounds, etc. Typical bleaching agents include organic complex salts of iron (1), such as ethylenediaminetetraacetic acid, Aminopolycarboxylic acids such as diethylenetriaminepentaacetic acid, cyclohexanediaminetetraacetic acid, methyliminodiacetic acid, 1,3-diaminopropanetetraacetic acid, glycol etherdiaminetetraacetic acid, or complex salts such as citric acid, tartaric acid, malic acid, etc. can be used. . Among these, aminopolycarboxylic acid iron (NL) complex salts, including ethylenediaminetetraacetic acid iron (III) complex salt and 1,3-cyanopropanetetraacetic acid iron (III) complex salt, are used from the viewpoint of rapid processing and environmental pollution prevention. Preference is also given to iron aminopolycarboxylate (I[[)
Complex salts are particularly useful in both bleach and bleach-fix solutions. These aminopolycarboxylic acid iron (I[[)
The pH of bleach or bleach-fix solutions using complex salts is usually 4.0.
~8, but it is also possible to process at an even lower pH for faster 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;

-95.630 are preferred. Furthermore, the compounds described in U.S. Pat. No. 4,552,834 are also preferred. These bleach accelerators may be added to light-sensitive materials. agents are particularly effective.

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 2.
-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, but thiosulfates are commonly used. Among them, ammonium thiosulfate is the most widely used. It is also preferable to use a combination of thiosulfate, thiocyanate, thioether compounds, thiourea, etc. As a preservative for fixing solutions and bleach-fixing solutions, sulfites, bisulfites, carbonyl bisulfite adducts, or European patented The sulfinic acid compounds described in No. 294769A are preferred. Furthermore, it is preferred 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°C to 5°C.
0°C1 is preferably 35°C to 45°C. In the 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 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 any of the bleaching solution, the bleaching window M'e, and the fixing solution. 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 above-mentioned stirring improving means includes:
It is more effective when a bleach accelerator is used, and the accelerating effect can be significantly increased and the fixing inhibiting effect caused by the bleach accelerator can be eliminated.

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 processing liquid from the front bath to the rear bath, and is highly effective in preventing deterioration of the performance of the processing liquid. This effect is particularly effective in shortening the processing time in each step and reducing the amount of processing solution 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 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 (stages), the replenishment method such as countercurrent flow, 1lII flow, etc.
It can be set in a wide range depending on various other conditions. Among these, the relationship between the number of washing tanks and the amount of water in the multistage countercurrent method is as follows:
Ty of Motion Picture
and Te1e-vision Engineer
s Vol. 64, P, 248-253 (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. In the processing of the color photosensitive material of the present invention, such problems can be solved by:
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 pu 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. 58-14834, 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. Examples of the dye stabilizer that can be used include aldehydes such as formalin and glutaraldehyde, N-methylol compounds, hexamethylenetetramine, and aldehyde sulfite adducts.

It is also possible to add various botanical agents and antifungal agents 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 the above-mentioned processing solutions are concentrated by evaporation during processing using an automatic processor or the like, it is preferable to add water to correct the shrinkage.

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. U.S. Patent No. 3,342,59

It was created.

(Preparation of sample 2/2) Sample 2/, except that the colored coupler Exc-j in the 2.3rd layer of sample 1.213 was replaced with ExC-/j in an equal molar amount. 2. Sample 2/1 in the same manner as 2/3,
2/? It was created.

Samples 20/-2/7 prepared as described above were subjected to the color development described above after imagewise exposure.

Table 2 shows the results of MTF of magenta color image, color separation degree of cyan color image, poor color development due to bleaching solution fatigue, and light stain.
I stopped it and showed it.

Further, the decrease in color development after the photosensitive material was left in a -iz 0c refrigerator for one week was expressed as a percentage of the color development of a sample that had not been refrigerated.

The method for measuring MTF is that of T.H. James (
T, H, James)! , 'The Theory,
1- The Photographic Process (TheT
theory of the Photographic
Process) 4th Edition” (Mac Mira 7 (Mac)
Published by Mil fan), / 1977), No.
It is described on pages 607 to 607.

The degree of color separation of the cyan color image is determined by performing imagewise exposure through a red separation filter and cyan density 3. It is expressed as the ratio of the density of the magenta component to the exposure point of o.

From the results in Tables 1 and 1 above, it can be seen that the cyan turnip 2 of the present invention
- By using this method, a cyan image with a preferable hue can be obtained, and even when using a tired and weak whitening liquid, there is little color development defect, and the cyan image has excellent fastness, sharpness, and color reproducibility. It has become clear that an excellent silver halide color photographic material can be obtained.
