Description

Detailed Description of the Invention (Industrial Application Field) The present invention relates to a silver halide color photographic light-sensitive material, and in particular contains a bleach accelerator-releasing compound (referred to as a BAR compound) and a phosphoric acid ester to facilitate desilvering. The present invention relates to a silver halide color photographic light-sensitive material in which the stability of the light-sensitive material is accelerated and the stability over time of the light-sensitive material is improved.

(Prior Art) When a silver halide color photographic light-sensitive material is exposed to light and then subjected to color development, an oxidized aromatic-amine developer and a dye-forming coupler react to form a color image. Generally, in this method, a subtractive color reproduction method is used, and in order to reproduce blue, green, and red, images of yellow, magenta, and cyan, which are complementary colors, are formed, respectively. In color photography, color-forming couplers are added to the developer solution or incorporated into light-sensitive photographic emulsion layers, blocks, and other color image-forming layers, and are combined with the oxidized product of the color developer formed by development. The reaction forms a non-diffusible dye.

The reaction between the coupler and the color developing agent takes place at the active site of the coupler, and couplers with hydrogen atoms at this active site have 4
Equivalent couplers are those which require stoichiometrically 4 moles of silver halide to form 1 mole of dye. On the other hand, those having an anionically detachable group at the active site are 2-equivalent couplers, i.e. couplers that require only 2 stoichiometric moles of silver halide to form 1 mole of dye; Compared to a 4-equivalent filler, the amount of silver halide in the photosensitive layer can generally be reduced and the film thickness can be made thinner, making it possible to shorten the processing time of the photosensitive material and further improving the sharpness of the color image formed.

Functional groups as groups capable of leaving the two-equivalent coupler, such as development inhibitors, fogging agents, developing agents, couplers, fluorescent brighteners, ultraviolet absorbers, bleach accelerators, dyes or dye precursors, silver halide solvents, etc. By using couplers, the performance of photosensitive materials is improved by giving the couplers various functions. These organic materials such as couplers and ultraviolet absorbers are generally dissolved in a high boiling point organic solvent, emulsified and dispersed in a hydrophilic colloid (eg, gelatin) in the presence of a surfactant, and then introduced into a photosensitive material.

(So-called oil droplet dispersion method and oil protection method)
An example of such a method is described in US Pat. No. 2,322,027, and examples of high-boiling organic solvents include diethyl phthalate, dibutyl phthalate, n-hexyl benzoate, N,N-diethyl lauramide, etc. .

Incidentally, silver halide color photographic materials are generally processed basically through a color development step and a desilvering step. In the color development step, the exposed silver halide is reduced by a color developing agent to produce silver, and the oxidized color developing agent reacts with a color former (coupler) to provide a dye image. The silver thus formed is oxidized by a bleaching agent in the subsequent desilvering step, and further transformed into a soluble silver complex by the action of a fixing agent, which is then dissolved and removed.

In recent years, there has been a strong demand in this industry for speeding up processing, that is, shortening the time required for processing, and in particular, shortening the desilvering step, which accounts for nearly half of the processing time, has become a major issue.

As a method for increasing the bleaching edge, Research Disclosure +-1 temk 24241, 11449, and JP-A-61-201247 describe bleach-accelerating compound-releasing couplers, which contain such bleach-accelerating compound-releasing couplers. It is known that the desilvering properties of silver halide color photographic materials can be improved by using silver halide color photographic materials.

(Intelligence B to be Solved by the Invention) A compound that releases a bleach accelerator or its precursor upon reaction with an oxidized product of an aromatic primary amine developer (
Although it has become possible to promote m-silver by introducing BAR compounds (hereinafter referred to as BAR compounds) into photosensitive materials, a new problem has arisen. That is, a problem has arisen in which a photosensitive material containing a BAR compound has an increase in Turnip IJ degree during storage, or in other words, a problem in which stability over time has deteriorated.

Accordingly, an object of the present invention is to provide a silver halide color photographic material in which desilvering is promoted and the material has excellent stability over time.

(Means for Solving the Problems) As a result of intensive studies aimed at improving the stability over time, the present inventors found that a silver halide color photographic photosensitive material having at least one silver halide emulsion layer on a support. The light-sensitive material contains a compound that releases a bleach accelerator or its precursor upon reaction with an oxidized product of at least one aromatic primary amine developer, and at least one phosphoric acid ester. It has been found that this can be achieved in a silver halide color photographic light-sensitive material characterized by the following.

Examples of JP-A-62-173467 include couplers that can also function as BAR compounds (Exemplary coupler (1), (
An example is described in which 3) and θ) are dissolved and dispersed in dibutyl phthalate and introduced into a photosensitive material.

However, according to the examples, only improved sensitivity and solidification of color images are claimed, but there is no mention of stability over time, and according to the examples in the specification of the present application, which will be described later, the stability over time is not necessarily good. It is clear that this is not the case.

(Remains hereinafter) The light-sensitive material of the present invention is provided with at least one silver halide emulsion layer of a front window chromatic layer, a glaucoligochromatic layer, and a red chromatic layer on a support. Generally, there are no particular restrictions on the number and order of the silver halide 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 the following order from the support side: a red-sensitive layer, a green-bewitching layer, and a blue-sensitive layer. However, depending on the purpose, the above arrangement may be reversed, or the arrangement 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 silver halide photosensitive layers and between the uppermost layer and the lowermost layer.

For cough intermediate layer, JP-A-61-43748 and JP-A-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 structure can be preferably used0
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-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 Bll/BL/GL/G) I/R11/R
Order of L or B) I/BL/GH/GL/RL/RH
They can be installed in the following order:

Further, as described in Japanese Patent Publication No. 55-34932, from the side farthest from the support, the blue-sensitive layer /G)I/
They can also be arranged in the order of RH/GL/RL. Furthermore, as described in JP-A-56-25738 and JP-A-62-63936, the blue-sensitive layer/GL/RL/GH/R)I may be arranged in this order from the farthest side from the support. You can also do it.

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 disposed, and three layers with different photosensitivity are successively lowered toward the support. Even when composed of 3N having 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-speed 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, containing about 30 mol% or less of silver iodide. . Particularly preferred is silver iodobromide or silver iodochlorobromide containing from about 2 mole percent to about 25 mole percent silver iodide.

Silver halide grains in photographic emulsions include those with regular crystals such as cubes, octahedrons, and tetradecahedrons, those with irregular crystal shapes such as spherical and plate shapes, and those with twin planes. may have crystal defects, or a composite form thereof.

−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 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, or in order to speed up the process, a bleach-fixing process may be performed after the bleaching process. 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 chromium (IV), li (II), peracids, quinones, nitro compounds, etc. are used.

Typical bleaching agents include ferricyanide; dichromate; organic complex salts of cobalt (I) or cobalt (1), such as ethylenediaminetetraacetic acid, diethylenetriaminepentaacetic acid, cyclohexanediaminetetraacetic acid, methyliminodiacetic acid, 1,3 - Aminopolycarboxylic acids such as diaminopropanetetraacetic acid, glycol ether diamine tetraacetic acid, or complex salts of citric acid, tartaric acid, malic acid, etc.; persulfates; bromates; permanganates; nitrobenzenes, etc. may be used. can. Among these, aminopolycarboxylic acid iron(II) complex salts and persulfates, including ethylenediaminetetraacetic acid iron(1) complex salts, are preferable from the viewpoint of rapid processing and prevention of environmental pollution. Furthermore, the aminopolycarboxylic acid iron(I[[) complex salts are particularly useful in both bleaching solutions and bleach-fixing solutions. PL of bleach solution or bleach-fix solution using these aminopolycarboxylic acid iron (I[[) complex salts
+ is usually 5.5 to 8, but to speed up processing,
It is also possible to process at even lower pH.

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

These bleach accelerators may be added to the photosensitive material. These bleach accelerators are particularly effective when bleach-fixing color photographic materials for posthumous images.

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.

It is typical for the silver halide color photographic material of the present invention to undergo a water washing and/or stabilization process 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
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
Chlorinated disinfectants such as isothiazolone compounds, cyabendazole, chlorinated sodium isocyanurate, and other benzotriazoles listed in the issue, "Chemistry of antibacterial and fungicidal agents" by Hiroshi Horiguchi, "Microbial Sterilization, sterilization, and anti-mildew techniques" and the Japan Antibacterial and Anti-Mildogaku Yoshihen [Encyclopedia of Antibacterial and Antifungal Agents" can also be used.

The pI (pI) 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 be set in various ways depending on the characteristics of the photosensitive material, its use, etc.
Generally, a range of 20 seconds to 10 minutes at 15 to 45°C, preferably 30 seconds to 5 minutes at 25 to 40'C 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 carried out; an example of this is a stabilization bath containing formalin and a surfactant, which is used as the final bath for color irradiation materials for shadows. Can be done.

Various chelating agents and antifungal agents can also be added to this stabilizing bath.

The overflow liquid resulting from the water washing and/or replenishment of the stabilizing liquid can also be reused in 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

Sample 1 except that the compound of the present invention was substituted as shown in
Samples 118 to 123 were prepared in the same manner as 01. However, EX-6 was replaced in an equimolar amount.

Two sets of the obtained samples 101-123 were prepared,
One was refrigerated for 7 days, and the other was stored for 7 days under high-temperature storage conditions, i.e., a temperature of 40°C and a humidity of 80%. After that, a wedge exposure of 20 CMS was applied at the tip of the mouth, and the following processing step (1) or treatment was performed, respectively. Processing of step (II) was performed. Thereafter, the amount of residual silver was measured using fluorescent X-rays on the samples that had been refrigerated and processed. Further processing steps (
For the samples subjected to 1) (samples with a large amount of residual silver are desilvered again) red light (samples 101 to 117)

The temperature was measured.

Tables 1 and 2 summarize the results of determining the difference in minimum concentration between samples subjected to post-treatment after high-temperature storage and samples subjected to post-treatment after refrigerated storage.

As is clear from Tables 1 and 2, it can be seen that the increase in minimum concentration due to high temperature storage is well suppressed in the samples of the present invention. It has already been recognized that the photographic performance corresponds well to the aging time and the above-mentioned high-temperature storage.

In addition, for samples using BAR compounds, all treatment steps (
It was found that the amount of residual silver in both 1) and (II) was 30 mg/po or less, which was a level that caused no practical problems. It is known that when the amount of residual silver exceeds 30 mg/cm, color reproducibility and gradation balance deteriorate. The residual silver amount of sample 101 of the comparative example was 48 ffig/po (processing step (1)) and 60 ffig/po.

The obtained samples 201 to 210 were stored under refrigeration and stored at high temperatures in the same manner as in Example 1, and then the amount of residual silver and the minimum concentration change were determined in the same manner as in Example 1 and summarized in Table 3.

As is clear from Table 3, it can be seen that the increase in minimum concentration during high-temperature storage is well suppressed in the samples of the present invention. In addition, it was found that in all the samples using the BAR compound, the amount of residual silver in both treatment steps (1) and (I[) was less than 30 g/rrf, which was at a level that caused no practical problems.

The amount of resident silver in Sample 201 of the comparative example was 104 B/rd (processing step (I)) and 128 mg/rd (processing step (■)).
