Description

Detailed Description of the Invention (Field of Industrial Application) The present invention relates to a silver halide color photographic light-sensitive material, particularly a silver halide color photographic light-sensitive material that has excellent color reproducibility, sharpness, and image storage stability. Regarding.

(Prior Art) In silver halide color photographic materials, the use of pyrazoloazole-type magenta couplers is already known as magenta couplers in order to improve color reproducibility.

(U.S. Patent No. 3.725067, Japanese Unexamined Patent Publication No. 1983-172
982, etc.) Compared to conventional magenta couplers and pyrazolone type couplers, this coupler has a sharper visible absorption spectrum of the coloring dye produced by development, and has less absorption in unnecessary regions, i.e., yellow and cyan components, and is especially useful for vermilion, red, Colors such as pink can be made very vivid.

In addition, color dyes, which are important for the preservation of images produced by photographing and developing silver halide color photographic materials, gradually change during long-term storage, and the photographic material after processing will last for a long time. Pyrazoloazole couplers are superior to conventional pyrazolone couplers in terms of one-color image storage stability, which has the disadvantage of discoloration when stored for a period of time, but they are still not sufficient. As a storage property improvement technique, it is known to use various anti-fading agents in combination.

Specific examples of organic anti-fading side are described in the following patent specifications:

/ 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-sensitizing layer, and a red-sensing layer on the support; There is no limit to the number of emulsion layers and non-photosensitive layers and to the type of stone. A typical example is a silver halide photographic film having on a support at least one light-sensitive layer consisting of a plurality of silver halide emulsion layers having substantially the same color sensitivity but different light sensitivities. The photosensitive layer is a unit photosensitive layer that is sensitive to blue light, green light, or red light, and multilayer silver halide color photography is generally used as a unit photosensitive layer in optical materials. The layers are arranged in this order from the support side: a red-sensitive layer, a green-mechanic 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 sandwiched between the same color-sensitive layers.

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 consisting of three layers with different photosensitivity, in which a silver halide emulsion layer with a low density is disposed and the photosensitivity gradually decreases toward the support. Even when it is composed of three layers with different photosensitivity, as described in JP-A No. 59-202464,
In the homochromatic layer, the medium-range emulsion layer/high-range emulsion layer/low-range emulsion layer may be arranged in this order from the side remote from the support.

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.

As mentioned above, various layer structures and arrangements can be selected depending on the purpose of each photosensitive material.

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, and stabilization.Also, the amount of replenishment can be reduced by using means to suppress 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 PL+, and high concentration of color developing agent.

After color development, the photographic opalescent layer is usually bleached.

The bleaching process may be carried out simultaneously with the fixing process (fixing process within H), or may be carried out separately. Furthermore, in order to speed up the process, a bleach-fixing process may be performed after the bleaching process. Depending on the purpose, treatment may be carried out in consecutive bleach-fixing baths, fixing treatment before bleach-fixing treatment, or bleaching treatment after bleach-fixing treatment. As bleaching agents, for example, compounds of polyvalent metals such as iron (I[+), peracids, quinones, nitro compounds, etc. are used. Typical bleaching agents include organic complex salts of iron (I[[), for example. Aminopolycarboxylic acids such as ethylenediaminetetraacetic acid, 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, iron(III) aminopolycarboxylic acids (I[[)[salts] include ethylenediaminetetraacetic acid iron(III) complex salts and 1,3-diaminopropanetetraacetic acid iron(I[[) complex salts]. Further, aminopolycarboxylic acid iron (I) is preferable from the viewpoint of prevention.
I) Complex salts are particularly useful in both bleach and bleach-fix solutions. These aminopolycarboxylic acid iron (II
I) The p)I of the bleach or bleach-fix solution using a complex salt is usually 4.0 to 8, but it is also possible to process at a lower pH for speeding up the process.

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.

Among them, compounds having a mercapto group or a disulfide group are preferable from the viewpoint of a large promoting effect, and in particular, compounds having a mercapto group or a disulfide group are preferred.
No. 858, West German Patent No. 1.290,812, JP-A-5
The compounds described in US Pat. No. 3-95, 630 are preferred, and the compounds described in U.S. Patent No. 4,552,834 are also preferred. These bleach accelerators are particularly effective when bleach-fixing color light-sensitive 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 2.
~5, specifically acetic acid, propionic acid,
Hydroxyacetic acid and the like 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. Preservatives for fixing solutions and bleach-fixing solutions include thiosulfate, bi[acid salts, and carbonyl bisulfite adducts]. Alternatively, the sulfinic acid compounds described in European Patent No. 294769A are preferred. Furthermore, various aminopolycarboxylic acids and organic phosphonic acids are preferably added to the fixing solution and bleach-fixing solution for the purpose of stabilizing the solution.

In the present invention, the fixer or bleach-fixer contains a compound having a pKa of 6.0 to 9.0 for p adjustment, preferably imidazole, 1-methylimidazole, 1ethylimidazole, and 2-methylimidazole. It is preferable to add 0.1 to 10 mol/2 of imidazoles.

The total time for 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°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. Specific methods for strengthening the agitation include the method of colliding a 91 flow of a processing liquid on the emulsion surface of a photosensitive material described in JP-A No. 62-183460, and the method described in JP-A No. 62-18.
A method of increasing the stirring effect using the rotating means of No. 3461,
Furthermore, a method of moving the photosensitive material while bringing the emulsion surface into contact with a wiper blade provided in the liquid to create turbulent flow on the hole side surface improves the stirring effect and increases the circulation flow rate of the entire processing liquid. One example is how to do it. Such means for improving agitation is effective for any of bleaching solutions, bleach-fixing solutions, and constant f 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 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
JP-A-60-191257, which preferably has the photosensitive material conveying means described in No.-1.91259.
As described in the above issue, 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 (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
urn-al of the 5ociety of
Motion Picture and Te1e-v
ision EngDreers Volume 64, P, 24
8-253 (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 water retention in the tank, bacteria propagate and the generated suspended matter adheres 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

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

The pl+ 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 temperature 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 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.

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 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

No. 144547 and No. 58-115438.

Various treatment liquids in the present invention are used at 10°C to 50°C. Normally, a temperature of 33°C to 38°C is standard, but higher temperatures can be used to accelerate processing and shorten processing time, or lower temperatures can be used to improve image quality and stability of the processing solution. can be achieved.

Trial 1f4102-130 was created by making the following changes.

Magenta coupler C-410g was heated and melted in tricresyl phosphate 2+d and ethyl acetate 20M1, and 1g of sodium dodecylbenzenesulfonate was added as a surfactant, and the mixture was stirred at high speed with 200g of a 5% gelatin aqueous solution using a stirring emulsifier. An emulsion was created.

Emulsions of magenta couplers were prepared by replacing C-4 with the respective couplers.

In addition, emulsions with different surfactants were created by changing the weight of sodium dodecylbenzenesulfonate to each of the surfactants listed in the table below.

The obtained samples 101 to 130 were evaluated by the following test method. The results are shown in Table 1.

Test method 1) Color purity test The "red" chart of the Macbeth standard color table was
Light the area with a daylight incandescent lamp adjusted to a color temperature of The sample was developed according to the processing steps described below.

The resulting sample was measured using a point measuring densitometer (X-Light, XLight).
The measurements were carried out at the following: The R density at the point corresponding to the G density of 3.0 was used as an index of color turbidity. The lower the R density (cyan component), the brighter the color group is.

2) Sharpness The MTF was determined by measuring the density of the exposed sample through a wedge for measuring MTF.

3) Color image storage properties The exposed and developed samples were stored for one week at a constant temperature of 80°C and 70%, and the ratio of the magenta density after storage to the magenta density immediately after development was determined.

It is clear that the cyan component that causes turbidity in the red image is very small, the colors are bright, and the image has excellent storage stability. Furthermore, the sharpness of the white layer and lower layer was not impaired, indicating that this is a color reversal photosensitive material that maintains excellent image quality.

Note that Samples 119 and 120 had smaller particle sizes than the other samples, and the maximum density at the time of color development was high.

1. ONP H5,0-7,0 In trial #J201, the magenta coupler ExM-5 in the 7th layer, 8th layer, and 9th layer was changed as shown in the table below,
In addition, the surfactant used when emulsifying this coupler is W-2.
Samples 202 to 230 were created by changing sodium dodecylbenzenesulfonate to those shown in the table.

The method for preparing the emulsion was based on Example 1.

Samples 201 to 230 were evaluated based on the following test method.

The results are shown in Table 2.

Test method: 1-color turbidity test The "green" chart of the Maches standard color table is illuminated with a daylight incandescent lamp whose color temperature is adjusted to 4800°, and the exposure is adjusted to take a photograph. The sample was developed according to the processing steps described below.

The obtained sample was subjected to point measurement type concentration 81 (X light,
(manufactured by Light Company). G
R711 degrees at a point corresponding to a density of 2.0 was used as an index of color turbidity. The smaller the R4 degree (Noan component), the brighter the color group.

2. Sharpness: The density of the exposed and developed sample was measured through a wedge for measuring MTF, and the MTF was determined.

3. Color image storage properties The exposed and developed samples were stored for one week at a constant temperature of 80'C and 70%, and the ratio of the magenta density after storage to the magenta density immediately after development was determined.

It can be seen that Samples 207 to 230 of the present invention are silver halide photosensitive materials that have little color turbidity and excellent color image storage stability without impairing the sharpness of the green-sensitive layer and the red-sensitive layer.
