Description

Detailed Description of the Invention (Industrial Application Field) The present invention relates to a large amount of silver halide color photographic material, and provides a color photographic material with excellent color reproducibility and improved processability. It is something.

(Prior Art) Color photography technology has made remarkable progress in recent years. Color photographic materials have undergone numerous improvements in many aspects, such as sharpness, granularity, color reproducibility, color image preservation, exposure light source suitability, processing stability, etc., and are now available in the form of integrated cutting-edge technologies. Ta.

Regarding sharpness and color reproducibility, compounds that release development inhibitors or their precursors (hereinafter abbreviated as DIR compounds)
The use of DIR couplers is important, and various DIR couplers have been developed to this day.

For example, British Patent No. 935,454, US Patent No. 3°227
．． No. 554, No. 4,095,984, No. 4.149,
When coupled with a color developing agent as described in No. 886 and JP-A No. 57-151944, the coupler core forms a dye while releasing the development inhibitor bound to the force-twisting site. , DIR that exhibits a development inhibitory effect
An example is a coupler. Also, U.S. Patent No. 3,652,34
No. 5, No. 3,928,041, JP-A-53-1105
No. 29, No. 54-13333, No. 55-161237
DIR couplers that release a development inhibitor but do not form a dye when subjected to a cambling reaction with an oxidized form of a color developing agent, such as those described in No. Also, JP-A No. 54-145135, No. 56-114946, No. 5
When reacted with an oxidized color developing agent such as that described in No. 7-154234, the mother nucleus forms a dye or a colorless compound, while the released timing group undergoes an intramolecular nucleophilic substitution reaction or an elimination reaction. Also included are 1DtR couplers that release development inhibitors.

Furthermore, the DIR coupler, which was developed to extend the effect of the development inhibitor from the layer containing the coupler to other layers in the color photosensitive material, releases a diffusible descendant development inhibitor. It is a sex DIR coupler, published in Japanese Patent Application Laid-Open No. 57-15
Examples include No. 1944 and No. 57-154234. In particular, the development inhibitor disclosed in JP-A No. 57-151944 exhibits development inhibitory properties when released from the coupling reaction, and when released into the processing solution, the development inhibitory effect is deactivated, thereby preventing contamination of the processing solution. It is an excellent DIR coupler with

By using these J) IR couplers, sharpness and color reproducibility have been considerably improved, but on the other hand, excessive use of these DIR couplers may result in a decrease in color development sensitivity or may require directional development processing. When this is done, an unnecessary development inhibitory effect occurs in the layer of the photosensitive material in the form of a tail in the direction opposite to the direction in which the processing progresses, resulting in the formation of an undesirable image. A directional development processing method is usually 1
Processing in which 35-size photosensitive materials are endlessly joined in a photofinishing laboratory, or processing using the roller transport method, crimping method, etc., such as the simple rapid processing machine called a minilab, which has become popular in recent years. is pointing to.

When designing color sensitive materials, it is desirable to use more than enough of such diffusive DIR couplers in each color-sensitive layer to improve sharpness and color reproducibility, but for the reasons mentioned above, the amount used is limited. was limited, and a method to improve this was desired.

JP-A No. 62-177557 discloses a method for improving preservability due to a diffusible DIR compound and non-photosensitive silver halide fine particles in a protective layer.
Improvements in development processing characteristics are cited, but with the slow yellow coupler used in the publication, diffusible DIR compounds cannot be used sufficiently, resulting in poor color reproducibility and sensitivity. It was insufficient in several respects.

(Problems to be Solved by the Invention) An object of the present invention is to provide a multilayer silver halide color photographic material with stable processability without impairing color reproducibility or sensitivity.

(Means for Solving the Problems) The present inventors have made extensive efforts to achieve the above object, and as a result have found that the above object can be achieved by the following method. That is, in a silver halide color photographic light-sensitive material having a blue-chromic layer, a green-sensitive layer, and a red-sensitive layer on a support, the following general formula [I] is used as a yellow dye-forming color coupler.
A compound containing at least one compound represented by and/or which reacts with an oxidized form of a color developing agent to release a diffusible development inhibitor or its precursor into the color-sensitive layer furthest from the support. Alternatively, a compound that cleaves the development inhibitor by reacting with an oxidized form of a color developing agent and then reacts with one more molecule of a color developing agent to cleave a development inhibitor is added at 1 mol to the photosensitive silver halide of the color sensitive layer. Contains more than %,
and a protective layer of a non-photosensitive hydrophilic colloid layer is provided on the side farther from the support than the color-sensitive layer, and the non-photosensitive fine grain silver halide is contained in the protective layer at a concentration 15 times that of the above compound. This was achieved by using a multilayer halogenated color silver photographic light-sensitive material characterized by containing more than mol of halogenated silver.

Next, the non-photosensitive fine grain silver halide related to the present invention will be explained.

Non-photosensitive fine grain silver halide is not exposed to light during imagewise exposure to obtain a dye image, is not substantially developed in the development process, and may be couplered in advance, but preferably in advance. These are uncoupled silver halide particles.

The fine-grain silver halide has a silver bromide content of 0 to 100 mol%, and as long as it contains silver bromide in this proportion, it may have various compositions. Good too. Silver chloride and/or silver iodide may be contained if necessary.

Preferably, silver iodobromide containing 0.5 to 10 mol% of silver iodide is used.

The fine grain silver halide has an average grain size of 0.01-0.
5 μm is preferable, more preferably 0.02 to 0.2
μm is used. The average grain size of silver halide grains means the average diameter of circles corresponding to the projected area of individual silver halide grains, and this measurement can be performed, for example, in "Fundamentals of Photographic Engineering - Silver Salt Photographic Layers - J (Japanese) It can be determined by the method described in pages 227 to 228 (edited by the Photographic Society, published January 30, 1976).

The fine-grain silver halide can be obtained in the same manner as in the preparation of ordinary photosensitive silver halide emulsions, or in accordance with the preparation of ordinary photosensitive silver halide emulsions.

In this case, the surface of the silver halide grains does not need to be optically sensitized, nor is there any need for fractional attenuation enhancement. However, before adding these fine silver halide grains to the coating solution, known stabilizers such as triazole compounds, azaindene compounds, benzothiazolium compounds, mercapto compounds, and zinc compounds are added in advance. It is preferable to keep it.

Such fine grain silver halide is added to at least one of the non-photosensitive hydrophilic colloid layers provided on the side remote from the support of the color-sensitive layer furthest from the support of the light-sensitive material of the present invention. The non-photosensitive hydrophilic colloid layer may be composed of one layer or multiple layers of two or more layers, and fine grain silver halide is contained in at least IN of jffJW, and the layer containing fine grain silver halide grains is a support layer. It may or may not be adjacent to the color-sensitive layer furthest from the body.

The amount of fine-grained silver halide added to the non-photosensitive hydrophilic colloid layer is influenced by factors such as the composition of the fine-grained silver halide, the grain size, and the amount of diffusible development inhibitor contained in the outermost color-sensitive layer. However, when the color-sensitive layer farthest from the support of the present invention contains a diffusible development inhibitor-releasing compound in an amount of 1 mol % or more based on the photosensitive silver halide in the same layer, the diffusible development inhibitor The molar amount is 15 times or more relative to the releasing compound. Preferably, the amount is 15 times to 1000 times, more preferably 20 times to 500 times.

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-phinidine diamine compounds are preferably used, and a typical example is 3-methyl-4-amino-N,N-diethylaniline. , 3-methyl-4-amino-N-ethyl-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. Although the amount of replenishment of these developing solutions depends on the color photographic light-sensitive material being processed, it is generally less than 3 Il per square meter of light-sensitive material, and by reducing the bromide ion concentration in the replenisher,
It can also be less than 〇-. 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.

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, it is possible to use a processing method in which bleaching is followed by bleach-fixing, furthermore, processing in two consecutive bleach-fixing baths, fixing before bleach-fixing, or bleach-fixing. A post-bleaching treatment can also be optionally carried out depending on the purpose. Examples of bleaching agents include iron (■), cobalt (T[
[), compounds of polyvalent metals such as chromium (■), copper (II), peracids, quinones, nitro compounds, etc. are used.
Typical bleaching agents include ferricyanide; dichromate; organic complex salts of iron (III) or cobalt (III), such as ethylenediaminetetraacetic acid, diethylenetriaminepentaacetic acid, cyclohexanediaminetetraacetic acid, methyliminodiacetic acid, and 1,3-diaminoacetic acid.

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

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, as a solution to such problems,
The method for reducing calcium ions and magnesium ions described in Japanese Patent Application No. 61-131.632 can be used very effectively. Also, JP-A-57-8,542

Generally, a range of 20 seconds to 10 minutes at 15-45°C, preferably 30 seconds to 5 minutes at 25-40°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. 57-8.543, 5B-14゜8
All known methods described in No. 34, No. 60-220.345 can be used.

Further, following the water washing treatment, a further stabilization treatment may be carried out, such as a stabilizing bath containing formalin and a surfactant, which is used as a final bath for color photosensitive materials for photography. .

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.

Table 1 shows the sensitivity of the blue-sensitive layer after subjecting the sample to white imagewise exposure and passing through the color development process shown below.

After imagewise wedge exposure with blue light and color development of the composition described above, a yellow color image shown in FIG. 1 was obtained. The density of the yellow component (Ds) and the density of the magenta component (DG) measured through a blue filter and a green filter are calculated by taking the ratio of D ts / D@ at an exposure amount where D is 2.5 and determining the blue sensation. The color separation of the layer was used as a measure of the color reproducibility of the blue-sensitive layer. The results are summarized in Table 1.

Stability with respect to processing directionality was evaluated as follows.

After the sample is irradiated with X-rays in a rectangular shape and subjected to the following treatment A and treatment B, the concentration of the rectangle is measured and the degree of deformation of the corners (i.e. edges) of the rectangle is calculated as (treatment B) / (treatment Stability with respect to processing directionality was evaluated in comparison with A).

Processing A: A rectangular (35 u x 12 ml) sample is passed through the processing process by vertically moving it up and down while keeping it perpendicular to the surface of the color developing solution having the composition described above.

(referred to as "hanging") Processing B: The same sample as above is moved through a processing step in a color developer having the composition described above so that the sample surface is parallel to the direction of movement of the sample. (Linear velocity 100C11/Monthin) That is, the second
If the image obtained after processing B with processing directionality by performing X-ray irradiation as shown in ■ in the figure is almost symmetrical as in processing A without processing directionality (O≦x/X ≦0.15
) is good, if some slight deformation is observed (0,05<
x / )
is not allowed. It is presumed that such image deformation due to processing directionality occurs because the diffusible development inhibitor generated in the image area (photosensitive area) moves to an undesired area and causes a decrease in density.

The above results are summarized in Table 1.

X is the concentration difference obtained by subtracting the background concentration of the unirradiated part of the sample from the maximum concentration of the X-ray irradiated part of the sample.

X is the difference in concentration between the highest and lowest concentrations of the xl irradiated portion of the sample; if x/X is small, the processability is good; if it is large, the unevenness depending on the processing direction is large.

As is clear from Table 1, the samples of the present invention do not suffer from a decrease in sensitivity, have good processing stability, and are excellent in color reproducibility.
