Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a silver halide color photographic light-sensitive material (hereinafter also referred to as "light-sensitive material") containing a novel yellow coupler and defining the amount of a high-boiling organic solvent used, More specifically, the present invention relates to a silver halide color photographic light-sensitive material having excellent sharpness using a yellow coupler that does not cause deterioration in color developability even when the amount of a high-boiling organic solvent used is reduced.

[0002]

2. Description of the Related Art In the subtractive method, an acylacetamide coupler represented by benzoylacetanilide type and pivaloylacetanilide type is generally used as a yellow coupler for forming a color photographic image.
The former generally has high coupling activity with the oxidized primary aromatic amine developer during development, and the molecular extinction coefficient of the yellow dye produced is slightly larger than that of the latter, so color sensitivity for photography that requires high sensitivity. Mainly used in materials,
The latter is mainly used in color papers and color reversal systems because the yellow dye has superior spectral absorption characteristics and fastness to the former.

In recent years, in silver halide color photographic light-sensitive materials, especially in photographic light-sensitive materials, high sensitivity represented by ISO400 light-sensitive material (for example, Super G-400 manufactured by FUJIFILM Corporation) having a high image quality of ISO sensitivity 100. There has been a demand for a light-sensitive material which has high sensitivity, excellent color reproducibility, and excellent sharpness. In addition, as one of the recent trends in color photography materials, there is a reduction in the size of the photography screen as seen in panoramic photography and an increase in the print enlargement ratio accompanying it, and improvement of sharpness in particular is a major issue. As a means for improving sharpness, it is well known to use so-called DIR compounds described in, for example, JP-A-54-145135, JP-A-56-114946 and JP-A-57-151944. Certainly, these compounds improved the edge effect and improved the sharpness to some extent, but these compounds released a sufficient amount of the development inhibitor to be released, and did not use a sufficient amount of silver halide. There is a problem that a sufficient edge effect cannot be obtained, and a problem that the sensitivity decreases when the amount of the DIR coupler used is increased, and the DIR coupler alone has a limit.

Another method for improving the sharpness is to reduce the thickness of the emulsion layer. In particular, it is effective to reduce the film thickness of the uppermost blue-sensitive layer in a normal photographic light-sensitive material. As an effective means for reducing the film thickness of the blue-sensitive layer, the color developability of the yellow coupler used in the blue-sensitive layer is improved, the amount of the high-boiling organic solvent used is reduced, or the molecule of the color-forming dye is used. A method of increasing the extinction coefficient can be considered. By these methods, the oil-soluble content in the layer can be reduced, and as a result, the hydrophilic colloid such as gelatin as a binder can be used in a reduced amount without deteriorating the film quality.

Regarding the yellow coupler having a higher molecular extinction coefficient than the benzoylacetanilide yellow coupler, a yellow coupler having a nitrogen-containing hetero ring in the acyl portion is disclosed in European Patent EP482552 as a yellow coupler having a novel acyl group. . However, although the molecular extinction coefficient is certainly improved in this yellow coupler, the decrease in color development is relatively large when the amount of the high boiling point organic solvent (oil) used is reduced, and the amount of the coupler used is increased. The effect of improving the sharpness was not sufficiently satisfactory. A yellow coupler having a cycloalkyl group in the acyl portion is disclosed in JP-A-4-218042.
No. Further, JP-A-5-5974 describes that a thin layer can be formed by reducing the amount of the high boiling point organic solvent used in the yellow coupler. Although the use of this coupler has some improvement in sharpness, it is still unsatisfactory, and the problem that film quality deteriorates when water-soluble colloid such as gelatin as a binder is reduced has become clear. .

The yellow coupler represented by the general formula (1) of the present invention is described in French Patent No. 991,453, US Pat. No. 2,500,487, and Japanese Patent Application Laid-Open No. 57-151944.
The structure is disclosed in JP-A-59-36249 and the like, but these patents do not describe the amount of dispersion,
It does not imply the present invention.

Development can be carried out by the usual method described in No. 307105, pages 880-881. The color developing solution used for the development processing of the light-sensitive material of the present invention is preferably an alkaline aqueous solution containing an aromatic primary amine type color developing agent as a main component. As the color developing agent, aminophenol compounds are also useful, but p-phenylenediamine compounds are preferably used, and typical examples and preferred examples thereof are compounds described in EP 556700A, page 28, lines 43 to 52. Is mentioned. Two or more of these compounds can be used in combination depending on the purpose. Color developers include alkali metal carbonates, pH buffers such as borates or phosphates, chloride salts,
Generally, a development inhibitor such as a bromide salt, an iodide salt, benzimidazoles, benzothiazoles or a mercapto compound or an antifoggant is contained. Also, if necessary, hydroxylamine, diethylhydroxylamine, sulfite, hydrazines such as N, N-biscarboxymethylhydrazine, phenylsemicarbazides, triethanolamine, various preservatives such as catecholsulfonic acids, ethylene glycol, Organic solvents such as diethylene glycol, benzyl alcohol, polyethylene glycol, quaternary ammonium salts, development accelerators such as amines, dye-forming couplers, competitive couplers, 1-
Auxiliary developing agents such as phenyl-3-pyrazolidone, viscosity imparting agents, aminopolycarboxylic acids, aminopolyphosphonic acids, alkylphosphonic acids, various chelating agents represented by phosphonocarboxylic acids, for example, ethylenediaminetetraacetic acid, Nitrilotriacetic acid, diethylenetriaminepentaacetic acid, cyclohexanediaminetetraacetic acid, hydroxyethyliminodiacetic acid, 1-hydroxyethylidene-1,1-diphosphonic acid, nitrilo-N, N, N-trimethylenephosphonic acid, ethylenediamine-N, N, Add N, N-tetramethylenephosphonic acid, ethylenediamine-di (o-hydroxyphenylacetic acid) and their salts.

When the reversal process is carried out, black and white development is usually carried out before color development. In this black-and-white developer, known black-and-white developing agents such as dihydroxybenzenes such as hydroquinone, 3-pyrazolidones such as 1-phenyl-3-pyrazolidone or aminophenols such as N-methyl-p-aminophenol are used alone. Alternatively, they can be used in combination. The color developing solution and the black and white developing solution generally have a pH of 9 to 12. The replenishing amount of these developing solutions depends on the color photographic light-sensitive material to be processed, but it is generally 3 liters or less per 1 square meter of the light-sensitive material. You can also do it. When the replenishment amount is reduced, it is preferable to prevent the liquid evaporation and air oxidation by reducing the contact area of the treatment tank with the air. The processing effect of the contact between the photographic processing liquid and air in the processing tank is the aperture ratio (= [contact area between processing liquid and air c
m ² ] ÷ [volume of treatment liquid cm ³ ]). The aperture ratio is preferably 0.1 or less, more preferably 0.001 to 0.05. As a method for reducing the aperture ratio, in addition to providing a cover such as a floating lid on the photographic processing liquid surface of the processing tank, a method using a movable lid described in JP-A-1-82033 and JP-A-63-216050 are disclosed. The slit development processing method described can be mentioned. The aperture ratio is preferably reduced not only in both the color development step and the black-and-white development step but also in the subsequent steps, for example, all the steps such as bleaching, bleach-fixing, fixing, washing, stabilizing and the like. Further, the amount of replenishment can be reduced by using a means for suppressing the accumulation of bromide ions in the developing solution. The time of color development processing is usually set between 2 and 5 minutes, but by using a high temperature, high pH and using a color developing agent at a high concentration,
Further, the processing time can be shortened.

The photographic emulsion layer after color development is usually bleached. The bleaching process may be performed simultaneously with the fixing process (bleach-fixing process), or may be performed individually. Further, in order to speed up the processing, a processing method of bleach-fixing processing after bleaching processing may be used. Further, treatment with two continuous bleach-fixing baths, fixing treatment before the bleach-fixing treatment, or bleaching treatment after the bleach-fixing treatment can be optionally carried out. As the bleaching agent, compounds of polyvalent metals such as iron (III), peracids, quinones, nitro compounds and the like are used. As a typical bleaching agent, an organic complex salt of iron (III),
For example, ethylenediaminetetraacetic acid, diethylenetriaminepentaacetic acid, cyclohexanediaminetetraacetic acid, methyliminodiacetic acid, 1,3-diaminopropanetetraacetic acid, glycol etherdiaminetetraacetic acid, and other aminopolycarboxylic acids or complex salts of citric acid, tartaric acid, malic acid, etc. Etc. can be used. Among them, ethylenediaminetetraacetic acid iron (III) complex salt and 1,3-diaminopropanetetraacetic acid iron (III)
II) Complex salts and other aminopolycarboxylic acid iron (III) complex salts are preferable from the viewpoint of rapid processing and prevention of environmental pollution. Further, the aminopolycarboxylic acid iron (III) complex salt is particularly useful in both the bleaching solution and the bleach-fixing solution. The pH of the bleaching solution or the bleach-fixing solution using these aminopolycarboxylic acid iron (III) complex salts is usually 4.0 to 8, but a lower pH can be used for speeding up the processing.

If necessary, a bleaching accelerator can be used in the bleaching solution, the bleach-fixing solution and their pre-bath.
Specific examples of useful bleaching accelerators are described in the following specifications: US 3,893,858, DE 1,290,812, 2,059,988, JP-A-53-32736, 53-57831, 53-37418, 53-72623. ,

The compounds described in 3,893,858, DE 1,290,812 and JP-A-53-95630 are preferable. Further, the compounds described in US 4,552,834 are also preferable. These bleaching accelerators may be added to the light-sensitive material. These bleaching accelerators are particularly effective when bleach-fixing a color light-sensitive material for photography. In addition to the above compounds, the bleaching solution and the bleach-fixing solution preferably contain an organic acid for the purpose of preventing bleach stain. Particularly preferred organic acids are compounds having an acid dissociation constant (pKa) of 2 to 5, and specifically acetic acid, propionic acid, hydroxyacetic acid and the like are preferable. Examples of the fixing agent used in the fixing solution and the bleach-fixing solution include thiosulfates, thiocyanates, thioether compounds, thioureas, and a large amount of iodide salts, but thiosulfates are generally used. Yes, especially ammonium thiosulfate can be used most widely. Further, it is also preferable to use a combination of thiosulfate, thiocyanate, thioether compound and thiourea. As a preservative for the fixing solution and the bleach-fixing solution, sulfites, bisulfites, carbonyl bisulfite adducts or sulfinic acid compounds described in EP 294769A are preferable. Further, addition of aminopolycarboxylic acids or organic phosphonic acids to the fixing solution or the bleach-fixing solution is preferable for the purpose of stabilizing the solution. In the present invention, the fixing solution or the bleach-fixing solution contains a compound having a pKa of 6.0 to 9.0 for pH adjustment, preferably an imidazole such as imidazole, 1-methylimidazole, 1-ethylimidazole or 2-methylimidazole. It is preferable to add 0.1 to 10 mol per liter.

The total time of the desilvering process is preferably as short as possible in the range where desilvering failure does not occur. Preferred time is 1 to 3 minutes
Minutes, more preferably 1 minute to 2 minutes. The treatment temperature is 25 ° C to 50 ° C, preferably 35 ° C to 45 ° C. In the preferable temperature range, the desilvering rate is improved, and the stain generation after the processing is effectively prevented. In the desilvering process, it is preferable that the stirring is strengthened as much as possible.
As a specific method for strengthening stirring, a method of impinging a jet of a processing solution on the emulsion surface of the light-sensitive material described in JP-A-62-183460, or a stirring effect by using a rotating means of JP-A-62-183461 is used. Method of raising, further moving the photosensitive material while contacting the emulsion surface with the wiper blade provided in the solution, to improve the stirring effect by making the emulsion surface turbulent, the circulation flow rate of the entire processing solution There is a method of increasing it. Such a stirring improving means is effective in any of the bleaching solution, the bleach-fixing solution and the fixing solution. It is considered that the improvement of the stirring speeds up the supply of the bleaching agent and the fixing agent into the emulsion film and, as a result, increases the desilvering rate. Further, the above-mentioned stirring improving means is more effective when a bleaching accelerator is used, and it is possible to remarkably increase the accelerating effect and eliminate the fixing inhibiting action of the bleaching accelerator. The automatic processor used for the light-sensitive material of the present invention is disclosed in JP-A-60-191257.
It is preferable to have the photosensitive material transporting means described in 60-191258 and 60-191259. As described in the above-mentioned JP-A-60-191257, such a conveying means can significantly reduce the carry-in of the treatment liquid from the front bath to the rear bath, has a high effect of preventing the performance deterioration of the treatment liquid, and It is particularly effective in shortening the processing time and reducing the replenishment amount of the processing liquid.

The light-sensitive material of the present invention is generally washed with water and / or stabilized after the desilvering process. The amount of rinsing water in the rinsing process depends on the characteristics of the light-sensitive material (for example, depending on the materials used such as couplers), application, and further the rinsing water temperature, the number of rinsing tanks (number of stages), replenishment system such as countercurrent, forward flow, and various other conditions Can be set in a wide range. Of these, the relationship between the number of washing tanks and the amount of water in the multi-stage countercurrent system is described in the Journal of t
he Society of MotionPicture and Television Enginee
It can be determined by the method described in rs Volume 64, P. 248 to 253 (May 1955). According to the multi-stage countercurrent method described in this document, the amount of washing water can be significantly reduced, but due to the increase in the residence time of water in the tank, bacteria propagate and the suspended matter produced adheres to the photosensitive material. Problem arises. As a solution to this problem, the method of reducing calcium ion and magnesium ion described in JP-A-62-288838 is extremely effective. Further, isothiazolone compounds and siabendazoles described in JP-A-57-8542, chlorine-based bactericides such as chlorinated sodium isocyanurate, and other benzotriazoles, Hiroshi Horiguchi, "Chemistry of Antibacterial and Antifungal Agents"
(1986) Sankyo Publishing, Sanitary Technology Association, "Microbial Sterilization, Sterilization, and Antifungal Technology" (1982) Industrial Technology Association, Japan Antibacterial and Antifungal Society, "Encyclopedia of Antibacterial and Antifungal Agents" (1986) The disinfectants described can also be used. The pH of washing water in the processing of the light-sensitive material of the present invention is 4 to 9, preferably 5 to 8.
The washing water temperature and washing time can be set depending on the characteristics and use of the light-sensitive material, but in general, a 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 light-sensitive material of the present invention can be directly processed with a stabilizing solution instead of the above washing with water. For such stabilization treatment, known methods described in JP-A-57-8543, JP-A-58-14834, and JP-A-60-220345 can be applied. Further, there is a case where further stabilization treatment is carried out after the water washing treatment, and an example thereof is a stabilizing bath containing a dye stabilizer and a surfactant used as a final bath of a color light-sensitive material for photographing. You can Examples of dye stabilizers 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 solution accompanying the washing with water and / or the replenishment of the stabilizing solution can be reused in other steps such as the desilvering step. In the processing using an automatic processor, etc., when the above processing solutions are concentrated by evaporation,
It is preferable to correct the concentration by adding water. The photographic material of the present invention may contain a color developing agent for the purpose of simplifying and accelerating the processing. For incorporation, it is preferable to use a precursor of a color developing agent. For example US 3,34

ExY-2, which is a benzoylacetanilide coupler, is excellent in color developability when the amount of the high boiling point organic solvent is relatively large, but the color developability is deteriorated when the amount of the high boiling point organic solvent used is reduced. It is large and is disadvantageous for thinning the photosensitive material. Also, comparison couplers RC-1 and RC-
In No. 2, although the oil amount dependency is improved to some extent, the color development at the time of oil reduction is not yet at a satisfactory level. On the other hand, the coupler of the present invention shows almost no decrease in color developability even when the amount of the high-boiling organic solvent used is reduced, and is extremely advantageous for thinning the light-sensitive material.

Development processing was performed as follows. The processing solution used was a standard exposure of Super G-400 manufactured by Fuji Photo Film Co., Ltd., which was processed until the replenishing amount of the color developing solution was three times that of the tank mother solution.

Example 2 Next, the effect of improving the sharpness and the film quality when the amount of gelatin was reduced were evaluated. Samples 201 to 233 were created by simultaneously making the following changes (1) and (2) for each sample created in Example 1. (Refer to Table-C) (1) Change in amount of coupler used In each sample prepared in Example 1, the coupler modified in Example 1 in the 11th layer was used so that the color development was the same as that of Sample 101. The amount used was adjusted. (However, the amount of the high-boiling organic solvent was also adjusted so that the oil / coupler ratio had the value shown in Table C.) (2) Reduction of gelatin amount The amount of gelatin used in the 11th layer was 1.0 g / m 2. Changed to ² .

The samples 201 to 233 thus obtained were subjected to the same exposure and development processes as in Example 1, and the same evaluation of color development as in Example 1 and the following evaluations were performed.

Evaluation 3. Sharpness Similar processing is performed for sharpness, and conventional MTF is used.
(Modulation Transfer Function) method, magenta image 20 cycles / m to evaluate the sharpness of the lower layer
The MTF value of m was determined and expressed as a relative value with the sample 201 set to 100.

Evaluation 4. Film quality (adhesion strength) Further, the adhesion strength of each sample was measured using the following method to evaluate the film quality. The adhesion strength was determined by scratching the emulsion surface (the surface on which the photosensitive emulsion had been coated) of the sample after development processing in advance, and then applying an adhesive tape and peeling it off at a constant speed. It was evaluated by measuring the area. In the test conducted here, knit-polyester adhesive tape No. 31 (manufactured by Nitto Denko Corporation) was used as an adhesive tape. The evaluation was carried out in the following five stages.

A: No peeling off B: Less than 5% peeled area C: 5% or more and less than 15% peeled area D: 15% or more but less than 35% peeled area E: 35% or more peeled area

[Table 6]

From the results shown in Table C, it was found that when the yellow coupler of the present invention was used with a reduced amount of oil and gelatin, the film quality was not deteriorated and the sharpness was remarkably improved. .

Example 3 A sample similar to the sample 101 in the example described in US Pat. No. 4,956,269 was prepared, and the yellow coupler C-5 in the 15th layer was used in the example 1. A sample was prepared in which the yellow coupler of the invention was replaced. These samples were evaluated for color developability and the evaluation performed in Example 2 using the processing method described in US Pat. No. 4,956,269. As a result, it was found that the light-sensitive material using the coupler of the present invention is excellent in color developability and improves sharpness without deteriorating film quality.
