Description

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, and more particularly to a silver halide color photographic light-sensitive material having improved color reproducibility and development processing stability.

[0002]

2. Description of the Related Art An excellent silver halide color light-sensitive material has a color reproduction that is faithful in terms of image quality, fine graininess, and sharpness that allows even fine details to be clearly expressed. In recent years, color negative photographic light-sensitive materials have been widely used in the world, and there are many kinds having different performances according to the purpose of use. As a usage method, it is generally used as a negative for photographic light-sensitive materials, and finally converted into a color positive light-sensitive material such as color photographic paper or color transparency and used in a form observed by the human eye. Is. Further, in some cases, the photographed positive image (color transparency or the like) may be converted into a different positive image (color photographic paper or the like) and used for viewing the image. There is also a color negative used for such a conversion, and the intermediate negative for conversion from positive-negative to positive-positive is known as color internegative. The process of printing from a color negative for movies to a positive for movies is generally negative (for photography) -positive-negative-positive (for projection), and the photosensitive material used in the middle is called intermediate film. It is widely used in the industry. It is essential that these light-sensitive materials propagate without impairing the original color (negative or positive image), graininess and sharpness. Conventionally, research has been conducted for improving image quality (color, graininess, sharpness) particularly in the above-mentioned light-sensitive material for color duplication, but it is still far from perfection.

Means for improving color reproducibility, which is one of image quality, is disclosed in, for example, JP-A-54-145135 and JP-A-56-135135.
It is well known to use so-called DIR compounds described in JP-A-114946 and JP-A-57-151944. Certainly, these DIR compounds improved the interlayer effect and improved the color reproducibility, but when the photosensitive silver halide grains became finer, the development activity of each grain increased, so the effect of the DIR compound was remarkably reduced. However, even if the amount used is increased, a sufficient inter-layer effect cannot be obtained, and it is extremely difficult to improve color reproducibility. On the other hand, a light-sensitive material using fine grain silver halide is EP-0492443A1, WO92 /
11573, JP-A-61-273543, 61-
No. 289341, No. 61-289346, No. 62-1
No. 8555, No. 63-30844, etc., but these have problems in color reproducibility. In addition, JP-A-6
-130531 states that the size of silver halide grains is generally selected from ultrafine grains of 0.05 μm or less to coarse grains of more than 2 μm, but these describe only emulsion grains having one layer. However, it is fundamentally different from the structure in which the effect is exhibited when the total photosensitive emulsion layer is 0.20 μm or less as in the present invention.

[0004]

That is, when the grain size of each emulsion grain is ri and the number is ni, the average grain size r is defined by r = Σni · ri / Σni, and the standard deviation S thereof is

The compounds described in 0 are preferred. 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 photographic material for photography. The bleaching solution and the bleach-fixing solution preferably contain an organic acid in order to prevent bleaching stain in addition to the above compounds. 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. Also,
Thiosulfates and thiocyanates, thioether compounds,
A combined use of thiourea is also preferable. 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 imidazoles such as imidazole, 1-methylimidazole, 1-ethylimidazole, and 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 so long as no desilvering failure occurs. Preferred time is 1 minute to 3
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 step, 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 for 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 consequently the desilvering rate. Further, the above-mentioned means for improving the stirring is more effective when a bleaching accelerator is used, and can significantly increase the accelerating effect or eliminate the fixing inhibiting effect 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 and magnesium ions described in JP-A-62-288,838 is extremely effective. Further, isothiazolone compounds and siabendazoles described in JP-A-57-8,542, chlorine-based germicides such as chlorinated sodium isocyanurate, and other benzotriazoles, Hiroshi Horiguchi, "Chemistry of antifungal agents"

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. In such stabilization treatment, known methods described in JP-A-57-8543, JP-A-58-14834, and JP-A-58-220345 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 fungicides can also be added to this stabilizing bath.

The overflow solution accompanying the above washing with water and / or supplementation 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 light-sensitive material of the present invention may contain a color developing agent for the purpose of simplifying and speeding up the processing. For incorporation, it is preferable to use a precursor of a color developing agent. For example US 3,34

^{2g / m 2, 0.02g / m} 2 in the fourth layer, 0.01 in the fifth layer
Sample 103 was prepared by adding g / m ² .

(Samples 104 to 106) As shown in Table 2, when the silver halide grain size of the blue-sensitive emulsion layers used in Samples 101 to 103 was increased, ExC-6 was used as a sample of 65% of Sample 102. Sample 106 was prepared by adding 105 and ExC-5 in the same amount as sample 103. At this time, the grain sizes of the red-sensitive emulsion layer and the green-sensitive emulsion layer are shown in Table 3. (Samples 107 to 109) Samples 107 to 109 were prepared by further increasing the grain size of the blue-sensitive emulsion layer used in Samples 104 to 106 and changing the amount of ExC-6 to 35% of that of Sample 102. Table 3 shows the grain sizes of the red and green emulsion layers.

(Samples 110 to 112) Samples 101 to 10
Samples 110 to 112 were prepared by making the emulsion grain size smaller than 3 and increasing the amount of ExC-6. (Samples 113 to 116) From Sample 103, the third, fourth, and fifth layers of yellow-colored couplers in YC-30 in equimolar amounts,
Sample 1 was changed to YC-31, YC-32, YC-47.
13-116 were created. The samples 101 to 116 thus obtained were subjected to white imagewise exposure and then subjected to the development processing (color development time 3'00 ") described later to determine the sensitivities of the red, green and blue photosensitive emulsion layers. Regarding these sensitivities, the relative sensitivities of the samples 102 and 103 are displayed for the samples 101 to 103 with the sensitivity of the sample 101 being 100. The relative sensitivities of the samples 104 to 106 to the sample 104 are displayed.
7, the sensitivity to the sample 110 is displayed. Sample 113
About -116, it displayed with respect to sample-101.

The following values were calculated and shown in Table 2 as a method of showing color reproducibility. After the red imagewise exposure, a uniform blue exposure is performed (the yellow density of the red unexposed portion of the sample 101 is 1.2 and the same process is performed to give a cyan density of 1.5). The value obtained by subtracting the yellow density at the cyan fog portion from the yellow density was determined as the color turbidity.The smaller this value, the less color turbidity and the better color reproducibility. After the exposure, only the color development time is 2'30 "and 3'3.
It was changed to 0 ″ and processed, and from the obtained sensitometry curve, (fog density + 0.2) and (fog density + 1.
The difference between the slopes of the straight line connecting the two points in 2) is displayed. It can be said that the smaller this value is, the less the variation in the development process is and the more stable the process is.
