Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention relates to a multilayer silver halide color photographic material, and more specifically to a silver halide color photograph that has good color development and maintains color balance even during rapid processing. Regarding photosensitive materials.

(Prior Art) In the formation of color photographic images based on the subtractive color method, aromatic-grade amine compounds, particularly M,M-disubstituted paraphenylene diamine compounds, which are developing agents, are generally used to form exposed photographic emulsions. A process is used in which the silver halide grains are converted to #R and the reaction of the reaction product with a coupler gives cyan, magenta and yellow dye images.

In recent years, rapid processing using a combination of high silver chloride emulsions and IZ)M has become common in developing silver halide color photographs using this method. High reactivity (hereinafter referred to as color development) is now required. Furthermore, at the same time as this rapid processing became widespread, benzyl alcohol, which had previously been contained in developing solutions as a color accelerator, was being removed due to environmental pollution and operational problems. As a result, there was a demand for couplers with even higher color development.

In order for a color photograph to exhibit excellent color reproducibility, the color balance of the three colors, ie, magenta, cyan, and yellow, is important. In other words, sufficient density (Dm) for all three colors
, and the gradations (7) must be well aligned. The magenta, cyan, and yellow couplers that have been studied and widely used have shown excellent color balance when subjected to conventional processing, but when the processing changes described above, the color balance is disrupted. However, most of the products could not be used without new technology.

The new technology involves changing the structure of the coupler itself,
Possible methods include improving the color-forming properties and adding new additives to compensate for the decrease in color-forming properties of couplers. In order to achieve balanced color development for all three colors using the former method, it is necessary to synthesize a large number of couplers for the five colors and select the optimal combination from among them.
Considering that couplers have a relatively complex structure and that they are expensive as organic materials, it can be easily inferred that they are extremely disadvantageous in terms of time and cost. On the other hand, in the latter method, if an effective additive is found, the color development can be adjusted by adjusting the amount of the additive. Is this additive non-color-forming and not related to color? Since it is b, there is a wide range of choice and there is a high possibility that a structure with low cost can be selected.

Many methods have been disclosed so far as methods for improving color development using additives. For example, JP-A-60

Recently, a ruthio-eliminating 2-equivalent coupler was disclosed in WO 38-04795, whose rapid processing suitability was improved over the previous 2-equivalent 5-bilazolone coupler. This type of coupler is a magenta coupler and has a tendency to improve color development and also has excellent color image retention. However, in order to obtain a color photograph with flat colorimetric reproducibility using this magenta coupler, the balance of the three colors is important, as mentioned above. However, when a color photograph is constructed by combining the coupler disclosed in the above-mentioned patent with yellow and cyan couplers known so far, it is not clear what additives should be added to maintain color balance after rapid processing. It was completely unclear whether the additive was effective as there was no mention in the patent regarding the additive.

(Problems to be Solved by the Invention) Therefore, the present invention provides a quick and effective color development promoter (by using an effective non-chromogenic color accelerator when a new arylthio leaving type 5-pyrazolone magenta coupler is combined with a known yellow cyan coupler). The purpose of this invention is to provide a silver halide color photographic material that does not lose its color balance even during processing and has ambiguous color reproducibility.

(Means for Solving the Problem) As a result of intensive studies aimed at achieving the above object, the inventors discovered that the following novel combination is an effective means, and have developed the present invention. It came to fruition. That is,
In a silver halide color photographic light-sensitive material having at least one red-sensitive, green-sensitive and blue-sensitive light-sensitive layer on a support, at least one coupler represented by the following general 2 [1] and/or [■], It contains at least one type of 5-pyrazolone coupler containing a leaving group represented by the following general 2 [melon], and at least one type of coupler represented by the following general 2 [■], and further contains the following general 2 [V co, Cvi ], [■], [l, [310[
The object has been achieved by a silver oxide color photographic light-sensitive material characterized in that at least one of the non-chromogenic substances represented by [X] and [X] is contained in at least one of the light-sensitive layers. .

The color photographic light-sensitive material of the present invention is constructed by coating at least one blue-sensitive silver halide emulsion layer, green-sensitive silver halide emulsion I-, and red-sensitive silver halide emulsion layer on a support. Can be done. In general color photographic paper, it is usually coated on the support as described above.
The chronology may be different from this. These photosensitive emulsion layers contain a silver halide emulsion sensitive to each wavelength range, and dyes that are complementary colors to the sensitizing light - yellow for blue, magenta for green, and cyan for red. By incorporating a so-called color coupler to form, subtractive color reproduction can be performed. It's nine,
The coloring hues of the photosensitive layer and the coupler may not correspond as described above.

As the silver halide emulsion used in the present invention, one consisting of silver chlorobromide or silver chloride that does not substantially contain silver iodide can be preferably used. Here, "substantially free of silver iodide" means that the silver iodide content is 1 molar or less, preferably 12 molar or less. The halogen composition of the emulsion may be different or the same among the grains, but if an emulsion having the same halogen composition among the grains is used, it is easy to make the properties of each grain uniform. In addition, regarding the composition distribution of NO to ROGE inside the silver halide emulsion grains, there are grains with a so-called uniform structure in which the composition is the same in any part of the silver halide grains, and cores inside the silver halide grains ( Particles with a so-called laminated structure in which the halogen composition differs between the core (core) and the shell L-layer or multiple layers surrounding it, or particles with a layered structure having different halogen compositions inside or on the surface of the particle in a non-layered manner ( If it is on the particle surface, particles with a structure in which portions of different compositions are joined to the edge, corner, or surface of the particle can be appropriately selected and used. In order to obtain high sensitivity, it is advantageous to use either of the latter two types of particles having a uniform structure, and it is also preferred from the viewpoint of pressure resistance. When silver halide grains have the above-mentioned structure, even if the boundaries between parts with different halogen compositions are clear boundaries, mixed crystals may be formed due to compositional differences, resulting in unclear boundaries. It is also possible to have continuous structural changes.

Regarding the halogen composition of these silver chlorobromide emulsions, any silver bromide/silver chloride ratio can be used. Although this ratio can vary widely depending on the purpose, those having a silver chloride ratio of 296 or more are preferably used.

Further, for light-sensitive materials suitable for rapid processing, emulsions with a high silver chloride content are preferably used. The silver chloride content of these high silver chloride emulsions is preferably 90 molt or more,
More preferably, the molar ratio is 95 or more.

In such a high silver chloride emulsion, it is preferable to have a silver bromide localized layer as described above in a layered or non-layered manner inside the silver halide grains and/or on the surface. The localized phase O halogen composition preferably has a silver bromide content of at least 10 mol, more preferably more than 20 mol*f. And these local layers are
It can be grown inside the grain, on the edge, corner, or surface of the grain surface, but one preferred example is epitaxial growth on a portion of the horn of the grain.

On the other hand, in order to minimize the decrease in sensitivity when a photosensitive material is subjected to pressure, even in a high silver chloride emulsion with a silver chloride content of 90 moles or more, grains with a uniform structure with a small distribution of halogen composition within the grains are used. It is also preferable to use

Furthermore, it is also effective to further increase the silver chloride content of the silver halide emulsion for the purpose of reducing the amount of replenishment of the development processing solution.

In the case of this rut, the silver chloride content is 98 mol% to 10
Emulsions of nearly pure silver chloride, such as those having a molar ratio of 0, are also preferably used.

Average grain size of the silver halide grains contained in the silver halide emulsion used in the present invention (the grain size is defined as the diameter of a circle equivalent to the projected area of the grain, and the number average thereof is taken)
is preferably 11μ to 2μ.

The particle size distribution is preferably so-called monodisperse, with a coefficient of variation (standard deviation f of particle size divided by average particle size) of 20% or less, preferably 15% or less. At this time, in order to obtain a wide latitude, it is preferable to blend the above-mentioned monodispersed emulsions in the same layer or to apply multilayer coating.

The shape of silver halide grains contained in photographic emulsions is regular (cubic, tetradecahedral, or octahedral).
It is possible to use those having an irregular (xar) crystal shape, irregular crystal shapes such as spherical or plate-like, or a composite shape thereof. Moreover, it may be made of a mixture of crystals having various crystal forms.

In the present invention, among these particles, the content of particles ft having the above-mentioned regular crystal form is preferably 50% or more, preferably 70% or more, and more preferably 90% or more.

In addition to these, the average aspect ratio (yen equivalent diameter/
Emulsions in which the tabular grains (thickness) of 5 or more, preferably 8 or more, exceed 50 percent of the total grains in terms of projected area can also be preferably used.

It can be prepared using the previously described method described in J.D.A., 1964). That is, any of the acidic method, neutral method, ammonia method, etc. may be used, and the method for reacting the soluble silver salt with the soluble halogen salt may be any method such as one-sided mixing method, simultaneous mixing method, or a combination thereof. May be used. A method in which particles are formed in an atmosphere containing excess silver ions (so-called back mixing method) can also be used. As one type of simultaneous mixing method, a method in which the pAg in the liquid phase in which silver halide is produced can be kept constant, that is, the so-called Chondrald double jet method can also be used. According to this method, a silver halide emulsion having a regular crystal shape and a nearly uniform grain size can be obtained.

Among the above-mentioned antifading agents, nuviroindanes and hindered amines are particularly preferred.

In the present invention, it is preferable to use the following compounds together with the above-mentioned couplers.

That is, compounds that chemically bond with the aromatic amino/developing agents remaining after color development processing to produce chemically inert and substantially colorless compounds; and/or aromatic compounds remaining after color development processing. For example, in storage after processing, the compound (G) that chemically bonds with the oxidized form of a group amine color developing agent to produce a chemically inert and substantially colorless compound may be used simultaneously or singly. This is preferable in order to prevent staining and other side effects caused by the formation of coloring dyes due to the reaction between the color developing agent or its oxidized product remaining in the film and the coupler.

The occupied area ratio (2) of eight-bed pigment fine particles per specified unit area is calculated by dividing the observed area into adjoining unit areas of 62 m x 6 μm, and calculating the projected area onto that unit area. It can be determined by measuring the occupied area ratio (equity) (R3) of the fine particles. The coefficient of variation of the occupied area ratio (4) is the standard deviation g of R3 with respect to the average value (i) of R1.
It can be determined by the ratio a/R. The number (n) of target unit areas is preferably 6 or more, so that the coefficient of variation s /T can be accommodated.

In the present invention, the coefficient of variation of the occupied area ratio (lack) of the pigment fine particles is less than cL15L15 [preferably less than L12. When the CLO is 8 or less, it can be said that the dispersibility of the particles is substantially uniform.

The silver halide color photographic light-sensitive material used in the present invention is generally washed with water and/or stabilized after desilvering treatment such as fixing or bleach-fixing.

The amount of washing water 1 used in the washing process varies widely depending on the characteristics of the photosensitive material (for example, depending on the materials used such as couplers), the purpose, the washing water temperature, the number of washing tanks (number of stages), the replenishment method such as countercurrent or forward flow, and various other conditions. Can be set to . Among these, the relationship between the number of flushing tanks and the amount of water in the multistage countercurrent method is described in the Journal Opinion of Motion Picture and Telecommunication Engineers (Journal
alof the 8ociety of Mot4o
n Picture and Telev-1aion
Engineers') Volume 64, P-248~2
55 (f? May 1955 issue). Generally, the number of stages in the multistage countercurrent system is preferably 2 to 6, particularly preferably 2 to 4.

According to the multi-stage countercurrent method, the washing water speed can be greatly reduced, for example, it is possible to reduce the amount of water from 0.5 t to 1 per 12 of photosensitive materials, and the effect of the present invention is remarkable. The increased residence time of water within the photosensitive material causes problems such as bacteria propagation and the resulting floating matter coming into contact with the photosensitive material. In the processing of the color light-sensitive material of the present invention, the method for reducing calcium and magnesium described in Japanese Patent Application No. 61-151i532 can be used very effectively as a solution to such problems.

It is also possible to use bactericidal agents described in "Encyclopedia of Bacterial and Antifungal Agents".

Further, in the washing water, a surfactant can be used as a draining agent, and a chelating agent such as EiDTm can be used as a water softener.

It is also possible to carry out the treatment with the stabilizing solution directly following the above-mentioned water washing step or without passing through the water washing step. A compound having an image stabilizing function is added to the stabilizing solution, such as an aldehyde compound typified by formalin, a buffer for adjusting membrane pH suitable for dye stabilization, and an ammonium compound. In addition, in order to prevent the proliferation of bacteria in the solution and to impart anti-mold properties to the photographic material after processing, the aforementioned various sterilizing agents and anti-mold agents can be used.

Furthermore, surfactants, optical brighteners, and hardeners can also be added. In the processing of the photosensitive material of the present invention, where stabilization is achieved directly without going through a water washing process, JP-A-57-

All known methods described in No. 45 and the like can be used.

In addition, it is also a preferable embodiment to use chelating agents such as 1-hydroxyethylidene-1,1-diphosphonic acid and ethylenediaminetemethylenephosphonic acid, and magnesium and bismuth compounds.

In the present invention, a so-called rinsing solution is also used as a washing solution or a stabilizing solution used after the desilvering treatment.

The pH of the water washing step or stabilization step of the present invention is 4 to 10, preferably 5 to 8. Temperature depends on the use of photosensitive materials.
Although the temperature can be set depending on the characteristics etc., the temperature is generally 15-45°C, preferably 20-40'C.

Although the time can be set arbitrarily, a shorter time is preferable from the viewpoint of reducing processing time. Preferably it is 15 seconds to 1 minute 45 seconds, more preferably 30 seconds to 1 minute 50 seconds. The smaller the amount of replenishment, the better from the viewpoints of cleaning/cleaning costs, reduction in emissions, ease of handling, and the like.

A specific preferable replenishment amount is O,S to 50 times, preferably 5 to 40 times, the amount of light-sensitive material brought in from the bath per unit area. Or, it is 1L or less per 1W of photosensitive material, preferably 500 or less. Further, replenishment may be performed continuously or intermittently.

The liquid used in the water washing and/or stabilization step can also be used in the previous step. In this column, the over-7-low wash water reduced by the multi-stage countercurrent system is flowed into the bleach-fixing bath, which is the previous bath, and the bleach-fixing bath is replenished with concentrated solution to reduce the amount of waste liquid. .

The total process time of the desilvering process, water washing and stabilizing process of the present invention is 2 minutes or less, preferably 50 seconds to 1 minute 50 seconds.

The total time here refers to the time from when the silver halide color photographic light-sensitive material comes into contact with the first bath in the desilvering process until it leaves the last bath in the water washing or stabilization process. 9 medium hours for movement O are included.

Here, "the sum of the processing time of desilvering treatment, water washing treatment, and stabilization treatment is 2 minutes or less" means that the total processing time of desilvering treatment, water washing treatment, and stabilization treatment is less than 2 minutes. For example, ■ Desilvering → Water washing ■ Desilvering → Stabilization ■ Desilvering → Water washing - Stabilization The sum of the processing times is less than 2 minutes.
