Description

Detailed Description of the Invention (Field of Industrial Application) The present invention relates to a silver halide color photographic material, and more particularly to a silver halide color photographic material with excellent sharpness and color reproducibility. It is.

(Prior Art) Color photographic materials have conventionally used couplers that release development inhibitors (DIR couplers) for the purpose of improving image sharpness and color reproducibility. The above-mentioned improvement in color image quality by DIR couplers is remarkable, and various DIR couplers have been developed or proposed with the aim of further improvement.

As a DIR coupler, for example, U.S. Pat. No. 3.127,
jju issue, same! , /ur, No. 062, same 3゜PI3.1
No. 00, Dotei, Da77. A coupler that releases a development inhibitor from the coupling position is disclosed in No. JAj.

In these DIR couplers, a development inhibitor is bound to the coupling position of the coupler, and therefore, in some cases where a development inhibitor is used, a problem arises in that the coupling reaction between the coupler and the oxidized developing agent is delayed. In order to improve this, it was necessary to interpose a linking group between the coupling position of the coupler and the development inhibitor. For example, US Patent No. ψ, l
ψ6゜No. 394, same 1. koψr, ytkogo and ytkogo.

This is a coupler described in Dako I, Rat issue, etc. These couplers certainly show improvement in the speed of the coupling reaction and have a certain degree of performance. However, when compared with a DIR coupler in which a development inhibitor is directly bonded to the coupling position and which originally has high reactivity with the oxidized developing agent, it was found that there is almost no difference.

Additionally, U.S. Patent No. 1,1731. /ri No. 3, same ψ, 3
No. 31.3?3, JP-A No. 1986-16-16-1 Button and AO-20J Tada No. 3 disclose examples of couplers that emit DIR couplers. Although the couplers described in these patents have shown some performance in improving graininess and sharpness, further improvements have been desired. In addition, with respect to improving color reproducibility, it has been found that there is a problem in that a portion of the dye produced when the released DIR coupler diffuses and further reacts with the oxidized developing agent remains in the sensitive material.

Furthermore, U.S. Patent No. φ, tie, r'yi, 17.
737. Gu! Couplers described in Japanese Patent Application Laid-Open No. 2003-23371, Japanese Patent Application Publication No. A/-+2337v1 and Japanese Patent Application Laid-open No. A/-2310!7 are known. The coupler described in this patent releases a compound (DIR redox compound) that releases a development inhibitor through an oxidation-reduction reaction, and is a type of D.
It is an IR coupler. The couplers described in these patents had few of the above-mentioned drawbacks and exhibited excellent performance in terms of improved sharpness due to the edge effect and improved color reproducibility due to the multilayer effect. However, these couplers are expensive to synthesize and have practical limitations, and further improvements have been desired.

(Problems to be Solved by the Invention) The object of the present invention is to provide a novel compound with excellent sharpness and color reproducibility by using a novel compound that can be manufactured at an appropriate cost and used in sufficient amounts. An object of the present invention is to provide a color photographic material.

(Means for Solving the Problems) The above object has been achieved by a silver halide color photographic light-sensitive material characterized by containing a compound represented by the following general formula [I].

- Formula (1) % Formula % The person in the formula represents a group that reacts with the oxidized developing agent to cleave the bond with (L)7-0-B, and L
Represents a group whose bond with O is cleaved after being cleaved from ViA, and B is a carbon atom that bonds with A-(L)AI-0-!
represents a 7- to 7-membered unsaturated heterocyclic group having 3 to 3 carbon atoms, and the heterocyclic group is selected from a hydroxy group, a sulfonamido group, an amino group, and a sulfamoylamino group in the ring-constituting carbon atoms. A group having a group and a development inhibitor group or its precursor as a substituent, l represents an integer from O to 2, and when l is 1, the two Ls may be the same or different.

In general formula [I], A is specifically a coupler residue i or a redox group that can be oxidized to cleave =(L)l-0-B. LH is a known timing group or linking group. The group represented by OB is A-(L)A during development.
! - is a group that can be oxidized by an oxidized developing agent after being cleaved.

That is, for the 0-BK button, 0 and R are at positions that satisfy the Kenda-Pelz rule. By being oxidized in this way, 0-B becomes a structure capable of releasing the development inhibitor group represented by R or its precursor. The release mechanism is nucleophilic addition of O-H to the oxidized form by a nucleophilic species.
This is elimination, and therefore R3, which is eliminated, must be substituted at the position where the nucleophilic species is added.

Nucleophiles are, for example, hydroxylamine, sulfite ions or hydroxide ions. The development inhibitor or its precursor released during development by the above mechanism exhibits an edge effect and a multilayer effect, thereby improving image sharpness and color reproducibility.

The coupler described in JP-A No. 4T-73314 has a heterocycle similar to some of the compounds of the present invention as a leaving group, but it does not have a development inhibitor or its precursor as a substituent. The improvements in sharpness and color reproducibility as described above were completely inadequate.

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 FWl (BH) /
High sensitivity green photosensitive layer (GH) /Low sensitivity green photosensitive layer (GL
) High-sensitivity red-sensitive layer (RH) / Low-sensitivity red-sensitive layer (
RL) or B) I/BL/GL/GH/RH/
RL order or BH/BL/Gl/GL/RL/RH

In the present invention, it is preferable to use non-light-sensitive fine-grain silver halide. Non-light-sensitive fine-grain silver halide is not exposed to light during imagewise exposure to obtain a dye image, but is not exposed to light during the development process. These are fine silver halide grains that are not substantially developed and are preferably not fogged in advance.

The fine-grain silver halide has a silver bromide content of 0 to 100 mol%, and may contain silver chloride and/or silver iodide as necessary, preferably silver iodide in a content of 0.5 to 100 mol%. It contains 10 mol%.

The fine grain silver halide preferably has an average grain size (average diameter equivalent to a circle of the projected area) of 0.01 to 0.5 μ■, and 0.
．． 02 to 0.2 μ- is more preferable.

Fine-grain silver halide can be prepared in the same manner as ordinary photosensitive silver halide. In this case, the surface of the silver halide grains does not need to be optically sensitized, nor is spectral sensitization necessary. However, prior to adding this to the coating solution, it is preferable to add in advance a known stabilizer such as a triazole-based, azaindene-based, benzothiazolium-based, or mercapto-based compound, or a zinc compound.

This can be cited as a representative example.

Further, when performing reversal processing, black and white development is usually performed and then color development is performed. This black-and-white developer contains known black-and-white developing agents such as dihydroxybenzenes such as hydroquinone, 3-pyrazolidones such as l-phenyl-3-pyrazolidone, or aminophenols such as N-methyl-p-aminophenol. They can be used alone or 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 to be processed, but is generally less than 32 torr per square meter of light-sensitive material, and by reducing the bromide ion concentration in the replenisher,
It can also be less than ad. 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.

Photo processing in a processing tank? The contact area between & and air can be expressed by the aperture ratio defined below.

In other words, the volume of the processing liquid! (cm') The above aperture ratio is preferably 0.1 or less, more preferably 0.001 to 0.05.

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 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 (bleach-fixing process), or in order to speed up the process, it may be carried out in two ways: bleach-fixing process after 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. Examples of bleaching agents include compounds of polyvalent metals such as iron (I[[), peracids2. Quinones, nitro compounds, etc. are used. Typical bleaching agents include complex salts of iron (I [ Aminopolycarboxylic acids such as -diaminopropanetetraacetic acid and glycol ether diaminetetraacetic acid, or complex salts such as citric acid, tartaric acid, and malic acid can be used.

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.

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 process, it is preferable to strengthen the stirring as much as possible.A specific method for strengthening the stirring is to impinge a jet of processing liquid on the emulsion surface of a photosensitive material as described in JP-A-62-183460. Method and JP-A-62-183
No. 461, a method of increasing the stirring effect using a rotating means, and further improving the stirring effect by moving the photosensitive material while bringing the emulsion surface into contact with a wiper blade provided in the liquid to create 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.

As stated in the issue, this type of 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.This effect reduces the processing time in each process. This is particularly effective in shortening the processing time and reducing the amount of processing liquid replenishment.

The silver halide color photographic light-sensitive material of the present invention is preferably subjected to a water washing and/or stabilization step after the 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 Engineers 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 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, 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 pH of the washing water in the processing of the photosensitive material of the present invention is 4 to 4.
9, preferably 5-8. The washing water temperature and washing time can also be set in various ways depending on the characteristics of the photosensitive material, its use, etc., but generally it is in the 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, such as a stabilizing bath containing a dye stabilizer and a surfactant, which is used as a final bath for color sensitive/optical materials for photography. Examples of dye stabilizers that can be mentioned include aldehydes such as formalin and glutaraldehyde, N-methylol compounds, hexamethylenetetrasilane, 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 a color developing agent, it is preferable to use various precursors of the color developing agent. U.S. Patent No. 3.342.59
