Description

TECHNICAL FIELD The present invention relates to a silver halide color photographic light-sensitive material, more specifically, desilvering in a processing step is promoted and stability of a raw light-sensitive material with time is improved. The present invention relates to an improved silver halide color photographic light-sensitive material.

(Prior Art) Generally, the basic steps of processing a color light-sensitive material are a color development constitution and a desilvering step. In the color developing step, the silver halide exposed by the color developing agent is reduced to form silver, and the oxidized color developing agent is used as a color forming agent (coupler).
To give a dye image. In the next desilvering step, the silver produced in the color development step is oxidized by the action of an oxidizing agent (commonly called a bleaching agent), and then dissolved by a complexing agent of silver ions, commonly known as a fixing agent. It By passing through this desilvering process, only a dye image is formed on the color light-sensitive material.

The above desilvering step is generally composed of two baths, a bleaching bath containing a bleaching agent and a fixing bath containing a fixing agent. However, a method using one bleach-fixing bath containing a bleaching agent and a fixing agent, a bleaching bath Various methods such as a method of providing a washing step between the fixing bath and the fixing bath are selected according to the light-sensitive material to be processed. However,
Highly sensitive color light-sensitive material during bleaching or bleach-fixing processing,
In particular, when processing a color reversal light-sensitive material for photography and a color negative light-sensitive material for photography having a large amount of coated silver, desilvering failure is likely to occur and bleaching requires a long time, so shortening the processing time is strongly desired. . Recently, along with the spread of minilabs, there is a tendency to shorten the processing time, and there is a strong demand for shortening the desilvering process, which has a large weight among the processing processes.

The most effective means of shortening the desilvering process is to use a bleaching accelerator. U.S. Pat.No. 3893858 includes a bleaching bath containing a water-soluble mercapto compound that is a bleaching accelerator.
Although it is described that the desilvering is promoted by adding it to the bleach-fixing bath or these pre-baths, the expected effect is hardly obtained due to the instability of the mercapto compound in the bleach-fixing bath or the bleach-fixing bath. Further, the method of adding to the pre-bath not only has a small accelerating effect, but also runs counter to the shortening of the necessity of newly adding a bath. On the other hand, in the method of adding a bleaching accelerator to a light-sensitive material, a mercapto compound having a high affinity for silver ions is added to a silver halide emulsion, which easily causes deterioration of photographic performance and stability over time. is expected.

As a method capable of solving these problems when using a bleaching accelerator, a bleaching accelerator releasing type coupler in which a bleaching accelerator or a precursor thereof is bonded to the coupling active position of the coupler is considered. This coupler is a coupler having a characteristic of releasing a bleaching accelerator by a coupling reaction with an oxidized product of an aromatic primary amine developing agent in a color developing step, Research Disclosure, No. 11449 (1973), N.
No. 24241 (1984) and JP-A No. 61-201247, specific examples thereof are described.

(Problems to be Solved by the Invention) Such a coupler can accelerate desilvering by simply adding it to a light-sensitive material without changing the processing step, and it was excellent in principle, but on the other hand, it was a serious problem. Brought. That is, when a light-sensitive material containing a bleach-accelerating agent-releasing coupler is stored in an unexposed (mainly) state, fog increases remarkably, which is a serious problem in terms of stability over time. The increase of fog with time leads to deterioration of photographic performance immediately, and is an important issue to be solved.

Therefore, an object of the present invention is to provide a silver halide color photographic light-sensitive material in which desilvering in the processing step is promoted and the stability of the raw light-sensitive material over time is improved.

When reversal processing is performed, black development is usually performed before color development. In this black-and-white developing solution, 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. Or in combination.

The color developing solution and the black and white developing solution generally have a pH of 9 to 12. The replenishment amount of these developing solutions depends on the color photographic light-sensitive material to be processed, but it is generally 3 or less per square meter of the light-sensitive material, and 500 ml can be obtained by reducing the bromide ion concentration in the replenishing solution.
It can also be: When the replenishment rate is reduced, it is preferable to prevent evaporation of the liquid and air oxidation by reducing the contact area of the processing tank with the air. Further, the amount of replenishment can be reduced by using means for suppressing the accumulation of bromide ions in the developing solution.

The color development processing time is usually set between 2 and 5 minutes, but the processing time can be further shortened by using a high temperature and high pH and using a color developing agent at a high concentration.

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 processing with two continuous bleach-fix baths,
The fixing treatment before the bleach-fixing treatment or the bleaching treatment after the bleach-fixing treatment can be optionally carried out according to the purpose.
Examples of bleaching agents include iron (III), cobalt (III),

Among these, iron (III) aminodicarboxylate iron (III) complex salts and other aminopolycarboxylic acid iron (II
I) Complex salts and persulfates are preferable from the viewpoint of rapid processing and prevention of environmental pollution. Furthermore, iron (III) aminopolycarboxylate
Complex salts are particularly useful in both bleaching solutions and bleach-fixing solutions. The pH of the bleaching solution or the bleach-fixing solution using these aminopolycarboxylic acid iron (III) complex salts is usually 5.5 to 8, but the processing can be carried out at a lower pH in order to speed 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 bleach accelerators are described in the following specifications: US Pat. No. 3,893,858, West German Patents 1,290,812, 2,059,98.
