Description

Ϊ́ Silver halide photographic material

The present invention relates to a novel silver halide color photographic light-sensitive material, and more particularly, to a silver halide color photographic light-sensitive material excellent in processing stability and pressure resistance. Background art

In recent years, the demand for silver halide color photographic light-sensitive materials (hereinafter simply referred to as color light-sensitive materials) has been increasing, and in addition to high sensitivity and high image quality, development processing has been carried out for the purpose of speeding up work and increasing efficiency. A high level of performance is required for faster and more stable operation.

Generally, when continuous development is performed in an automatic developing machine used in a large-scale processing laboratory, a small developing machine used in stores, or a so-called mini-lab, the film to be processed is usually used. Depending on the area, a certain amount of each developing replenisher is replenished, and the processing solution is controlled so as to always have a constant processing characteristic or composition. There is also a method of constantly monitoring the development activity of the processing solution and making corrections as necessary. There is no problem if the quality of the developing solution is strictly controlled in this Didi. For example, when the amount of film processed per hour is small, when unconventional processing is performed, or when moisture is When the evaporation amount is abnormally large, or when the developing process is restarted after the developing process has been stopped for a long time between holidays, etc., the activity of the developing solution tends to fluctuate. In such a processing environment, processing of silver halide color photographic light-sensitive materials, for example, color negative film, causes fluctuations in minimum density (force pre-density), maximum density, sensitivity, and gradation. This results in variations in print quality when printed on one paper.

Various attempts have been made to impart processing stability to silver halide color photographic light-sensitive materials in such a development processing environment. For example, methods for improving the composition and structure of the photosensitive silver halide particles, A method for improving the composition of a silver halide photographic light-sensitive material, for example, a layer constitution, a film thickness, a degree of hardening, etc., a method for improving with an oil-soluble additive, for example, a coupler, a DIR coupler, or a developing method. Methods using stabilizers and development inhibitors are known. However, the methods proposed to improve the stability to image processing often involve other photographic performance degradation, making it difficult to achieve a balance between processing stability and photographic performance. It is.

On the other hand, in the case of color light-sensitive materials, especially multi-layer color light-sensitive materials, non-photosensitive fine silver halide particles are added to the protective layer to suppress fluctuations in photographic performance due to fluctuations in the composition of the developing solution. It is known in the art that silver halide is contained (for example, see Patent Document 1). According to this method, a non-photosensitive fine grain silver halide having a particle size of 0.04 m or less is added to the protective layer. This is to prevent diffusion into the material and to prevent the inhibitory components generated by the development reaction from flowing out and accumulating in the developing solution. It has been found that the stabilizing effect against the change of iodine ion in the developing solution is insufficient with the improvement means using only silver halide. In the case of a multi-layer color light-sensitive material, the silver halide light-sensitive layer located at the outermost layer, specifically, the blue light-sensitive layer, tends to be susceptible to processing fluctuations. Various attempts have been made to improve the processing sensitivity of the blue light-sensitive layer by using silver halide emulsions or couplers, but it is still difficult to say that the quality is still satisfactory. In recent years, benzoylacetanilide-type yellow couplers having excellent color developing properties and color reproducibility have been proposed (for example, see Patent Document 2). For the purpose of further improving the color reproducibility of yellow one-color images, an acetoanilide-type coupler to which [1,2,4] thiadiazine-1,1-dioxide is bonded has been proposed (for example, Patent Document 3). Excellent color reproduction (yellow and white) and excellent white stability in bright and dark storage due to silver halide color photographic materials in which yellow dye has a specific normalized spectral absorption. O is obtained

The benzoylacetanilide-type yellow couplers or the [1,2,4] thiadiazine-1,1-dioxide-bonded acetoanilide-type couplers described in Patent Documents 2 and 3 have high coloring properties. Although this is an advantageous property for improving photographic performance, there is no mention of stability against the composition of the developing solution, and no application example is disclosed.

On the other hand, the development processing speed and the development time have been shortened, and the development processing speed has been remarkably increased. As a result, undesired scratches are generated in the processing tank due to contact between the processing equipment used and the color photosensitive material. The problem of color development has become apparent.

This is because the film that has swelled and becomes flexible in the developing solution comes into contact with a part of the equipment, for example, the surface of the transport roller, and the stress propagates to the photosensitive layer to expose it to light. Is a phenomenon, also called pressure, that occurs This causes a problem during printing and is a problem. It is said that increasing the thickness of the protective film is effective against this submerged pressure. However, simply increasing the thickness of the protective film cannot provide a sufficient effect. As a result, this results in a reduction in processing and processing fluctuations, and urgent improvement is required.

The present invention has been made in view of the above problems, and an object of the present invention is to provide a silver halide color photographic light-sensitive material having excellent processing stability and improved pressure resistance.

<< Characteristic evaluation of each sample >> [Evaluation of development processing stability 1]

(Exposure and development processing)

Each of the samples prepared above was exposed through a page in accordance with JISK 7614-1981, and then developed according to paragraphs [0220] to [0227] of JP-A-10-123652. According to the processing method, the amount of potassium iodide in the composition of the color developing solution was changed except that two kinds of color developing solutions of 1.2 mg / L solution (standard processing solution) and 1.5 mg / L solution were used. Similarly, each color developing process was performed. Then, for each of the color-developed samples, the densities of yellow, magenta and cyan were measured using a densitometer manufactured by X-rite, which is a transmission densitometer. An og E characteristic curve was created.

(Evaluation of processing stability)

In each of the yellow density characteristic curves of the photographic D-L 0 g E characteristic curve created above, the reciprocal of the exposure required to obtain a density of +0.10 from the minimum density is defined as sensitivity, The sensitivity fluctuation width (ΔS) between the reference processing solution with the added amount of potassium of 1.2 mg ZL solution and the sample processed with the color developing solution of 1.5 mg / L solution was determined, and this was calculated as the processing stability 1 ( (Iodine ion concentration dependence in treatment liquid). A smaller value indicates better processing stability.

[Evaluation of development processing stability 2]

(Exposure and development processing)

Each of the prepared samples was exposed through a page in accordance with JISK 76 14-1981, and then described in paragraphs [0220] to [0227] of JP-A-10-123652. One round of continuous processing using an automatic processor according to the processing method and replenishing the replenisher in a specified amount according to the processing area (Running processing) was performed to evaluate the stability of the image processing.

Blue sensitivity SB obtained by processing each sample using the developing solution at the start of processing in the standard development processing. When the blue-sensitive sensitivity S _{B 1} obtained by processing each sample after the running processing of one round is measured, determined the sensitivity variation ratio SB according to the following equation

5 33 indicates that the closer to 1.0 the value, the better.

B— S B 1 / B 0

Note that the above continuous processing was performed using a film obtained by randomly photographing a landscape photograph of Centnuria 100 and Centuria 400, which are color negative films manufactured by Konica Corporation. In the present invention, one round means a point in time when the integrated amount of the color developing solution replenishment amount 10 reaches the same amount as the processing tank volume of the color developing solution. In addition, the blue sensitivity was expressed as the reciprocal of the exposure required to obtain a density of minimum density + 0.3.

[Pressure resistance: evaluation of liquid pressure]

For each 35 mm x 15 10 cm sample that had been processed in one round, which was created in the evaluation of processing stability 2 above, using a loupe, transmitted light using a loupe caused scratches in the sample, and the occurrence of one-color spots (yellow one color) The presence or absence of pressure was observed, and the pressure resistance was evaluated according to the following criteria.

◎: Scratches are observed, but no yellow coloring marks are observed. 〇: Scratches are observed, and pale yellow coloring marks are slightly observed, but there is no practical problem.

Δ: Yellow-colored marks are observed with the occurrence of abrasions, but the color density is low and this is a practically acceptable limit.

X: Yellow color spots were observed due to scratches, and the color density was slightly high. Out of acceptable range for practical use

X X: Strong yellow coloration is observed with the occurrence of abrasion, which is out of the allowable range that poses a practical problem.
