Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a silver halide photographic material with high sensitivity, excellent sharpness and graininess, and little increase in fog or sensitivity when stored under high humidity. .

(Prior Art) Silver halide color photographic light-sensitive materials for photography, whether negative or reversal, are required to have high sensitivity and excellent image quality such as sharpness and graininess.

Normally, in a multilayer silver halide color photographic light-sensitive material having blue-sensitive, green-sensitive and red-sensitive silver halide emulsion layers, light scattering by silver halide grains affects the lower emulsion layer. It is known to reduce sharpness. On the other hand, US Pat. No. 4,439,520 and the like disclose multilayer color photographic materials that have high sensitivity and improved sharpness by using tabular silver halide grains.

Furthermore, Japanese Patent Publication No. 11386/1983 discloses a silver halogen photographic light-sensitive material whose graininess is improved by using a monodispersed emulsion.

Therefore, by appropriately combining emulsion layers containing the above-mentioned tabular grains and monodispersed grains, it is possible to simultaneously improve sharpness and graininess.

On the other hand, from a practical point of view, it is strongly desired to provide a stable silver halide photographic material that not only has high sensitivity and high image quality but also exhibits little fog or change in sensitivity during storage. However, the shape or crystal phase of silver halide grains that have high sensitivity, high image quality, and stable performance during storage have not been disclosed to date. For example, JP-A-6177847 discloses a photographic material using tabular silver halide grains in the highest-sensitive layer and monodisperse silver halide grains in the lower-sensitivity layer. Furthermore, there have been no regulations regarding the crystal phase of monodisperse particles, which is intended to improve color reproduction and is more preferable from the viewpoint of stability over time during storage.

(Problems to be Solved by the Invention) An object of the present invention is to provide a silver halide photographic material that has high sensitivity, high image quality, and high stability under storage conditions of high humidity.

(Means for solving problems) The above problem was solved by the following means.

That is, a plurality of silver halide emulsions having a plurality of silver halide emulsion layers having different color sensitivities on a support, each of which has substantially the same color sensitivity, and different sensitivities. In a color photographic light-sensitive material composed of layers, at least one of the color-sensitive layers is occupied by the highest sensitive layer, and 50% or more of the total projected area of the same color-sensitive layer has a thickness of 0.25 mm. 5μ

This is a silver halide color photographic light-sensitive material characterized by being composed of a 0) surface.

The present invention will be explained in detail below.

The light-sensitive material of the present invention has silver halide emulsion layers having different color sensitivities, such as a blue-sensitive layer, a green-sensitive layer, and a red-sensitive layer, on a support. Further, these color-sensitive layers are constituted by a plurality of silver halide emulsion layers having substantially the same color sensitivity but different sensitivities. The above color-sensitive layers are usually arranged in the order of a red-sensitive layer, a green-sensitive layer, and a blue-sensitive layer from the support side. However, even if the above arrangement differs depending on the purpose, it is still the same.
It is also possible to adopt an arrangement in which different color-sensitive layers are sandwiched between color-sensitive layers.

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.

The intermediate layer includes JP-A Nos. 61-43748 and 59-1.
No. 13438, No. 59-113440, No. 61-20
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. Also, JP-A-57-

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 BH/BL/GL/GH/RH/RL, or BH/BL/GH/GL/RL/RH They can be installed in the following order:

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 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 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.

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.

The most sensitive layer of at least one color sensitive layer of the present invention contains tabular silver halide grains. The tabular silver halide grains that can be used in the present invention will be explained below.

In the present invention, tabular silver halide grains (hereinafter referred to as "tabular grains") having an aspect ratio of 3 or more are defined as having two opposing parallel principal planes, and having a circular equivalent diameter of the principal planes (same as the principal planes). A particle in which the diameter of a circle having a projected area) is three times or more larger than the distance between principal planes (i.e., the thickness of the particle).

The average grain diameter/grain thickness ratio of the emulsion having tabular grains of the present invention is preferably from 3 to 12, particularly preferably from 5 to 10.

Here, the average grain diameter/grain thickness ratio is obtained by averaging the grain diameter/grain thickness ratio of individual tabular grains, but as a simple method, it is obtained by averaging the average diameter of all tabular grains,
It can also be determined as a ratio to the average thickness of all tabular grains.

The ratio of tabular grains to the projected area of all grains in the emulsion layer is 50% or more, preferably 70% or more.

The diameter (circular light) of the tabular grains of the present invention is 0.3 to 10 μm
Preferably 0.5 to 5.0 μm, more preferably 0.5 μm.
It is 5 to 2.0 μm.

Particle thickness is 0. 5 μm or less, preferably 0.05 to 0
．． The thickness is preferably 5 μm, more preferably 0.08 to 0.3 μm.

The particle diameter and particle thickness in the present invention can be determined from electron micrographs of the particles by the method described in US Pat. No. 4,434,226.

This can be accomplished by appropriately combining the methods described in 4306, 4435501, and the like.

For example, a seed crystal containing tabular grains of 40% or more by weight is formed in an atmosphere with a relatively high pAg value of pBrl, 3 or less, and a silver and halogen solution is added while maintaining the pBr value at the same level or higher. It is obtained by growing seed crystals.

In the above grain growth process, it is desirable to add a silver and halogen solution to prevent the generation of new crystal nuclei.

The size of the tabular grains can be adjusted by controlling temperature, selection of the type and amount of solvent, silver salt used during grain growth, rate of addition of halide, etc.

The tabular grains that can be used in the present invention are prepared by adding a silver salt solution (for example, A g N

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 set to I11 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,

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.

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.

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

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, thionanates, thioether compounds, thioureas, and large amounts of iodide salts, but thiosulfates are commonly used. Among them, ammonium thiosulfate is the most widely used.

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.

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

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 ~
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. 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.
A method of increasing the stirring effect using a rotating means as described in No. 461, and further improving the stirring effect by moving the photosensitive material without bringing the wiper blade provided in the liquid into contact with the emulsion surface and creating 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
urn-al of the 5ociety
of Motion Picture and
Te1evision Engineers No. 64
Vol., p. 248-253 (May 1955 issue).

According to the multi-stage countercurrent method described in the above-mentioned document, 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, grouper terriers breed, and the resulting floating 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

The washing water temperature and washing time can 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 process, a further stabilization process may be carried out. For example, a stabilizing bath containing a dye stabilizer and a surfactant, which is used as a finishing bath for color photosensitive materials for photography, may be further carried out. can be mentioned. Examples of the dye stabilizer 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 resulting from the water washing and/or replenishment of the stabilizing liquid can also be reused in processes such as the desilvering process.

When processing using an automatic processor, etc., if the above processing solutions become concentrated due to evaporation, add water! ! It is preferable to correct it.
