Detailed Description of the Invention

[0001]

FIELD OF THE INVENTION The present invention relates to a method for processing a silver halide photographic light-sensitive material, and more particularly to a highly stable processing.

[0002]

2. Description of the Related Art Silver halide photographic light-sensitive materials are used in the platemaking field,
It is used in a wide range of fields such as the medical diagnostic field. As the field of use expands and deepens, the demand for development processing steps necessary for image formation increases, and in particular, rapid and stable development processing is strongly desired. After exposure, the silver halide photographic light-sensitive material is generally processed in the steps of developing, fixing and washing. Among them, the black-and-white developing solution is generally an alkaline solution containing hydroquinone as a developing agent, aminophenols or 3-pyrazolidones as an auxiliary developing agent, and a sulfite.

This sulfite is used in the form of an alkali metal sulfite or bisulfite, and is an essential component for maintaining the developing activity of hydroquinones and for suppressing the air oxidation of the developing solution. is there. Sulfite may also be used in a method of improving graininess by positively utilizing a so-called dissolution physical development action in the development reaction process, which has an action of appropriately dissolving silver halide. On the other hand, the developer is desired to have higher stability (preservation). If the developer is stable against air oxidation for a long time, a certain photographic performance can be obtained without any trouble in maintaining and managing the developer. In particular, when maintaining and managing the liquid composition while replenishing a certain amount of replenisher with an automatic processor (hereinafter referred to as an automatic processor), both the amount of replenisher and the running cost can be reduced. It's important. In order to reduce the amount of this replenisher, the developer stability must be higher. The decrease in the amount of the replenisher is because the residence time of the developer in the developing machine and the tank of the replenisher is further lengthened, and the degree of air oxidation of the developer is greatly increased.

Air oxidation of the developing solution can be prevented by increasing the sulfite concentration in the developing solution, but there is a limit to increasing the sulfite concentration. One of the reasons is as follows. That is, usually, a concentrated solution prepared by concentrating the developing solution to several times is prepared, and it is used by diluting it when actually developing it. One of the largest factors controlling the concentration of this concentrated solution is sulfite. . If a large amount of sulfite is added to increase the stability of the developer, the concentration will decrease.In an extreme case, the same concentration will be obtained from the time when the developer is first prepared to the time when it is used on-site in the developing machine. That is, the same volume of developer is used, which is very disadvantageous both in terms of transportation and space. Another reason is that a developer containing a large amount of sulfite increases the dissolution and elution of silver halide from the silver halide light-sensitive material, resulting in a large amount of silver stain in the developer and promoting stains on the developing rack and rollers. Because it will be done.

For these reasons, there is a limit even if it is desired to include a large amount of sulfite which is effective in improving the stability of the developing solution in the developing solution, and as described above, further stability,
In recent years, there have been increasing demands for improved homeostasis. Ascorbic acid is known as a means for improving the preservative property of a developing solution. Known techniques for adding to a lith developer include, for example, Japanese Examined Patent Publication (Kokoku) No. 44-28673, and the disadvantages of ascorbic acid are that as the ascorbic acid deteriorates, the pH of the developer lowers, and the developer is easily decomposed. It is mentioned that when metal ions such as copper ions and iron ions are present, they are easily decomposed. The ascorbic acid derivative is a compound that has been known for a long time, and there are other examples of use in the art as well. US Patent No. 26
In JP-A-88549 and JP-B-36-17599, it is used as a developing activity, gradation improvement, and a preservative for 3-pyrazolidones. Actually, when this compound was evaluated, it has an excellent air oxidation suppressing function of the developer,
The problem is that the developing activity is lowered because the pH of the developing solution is lowered. The acetoins described in British Patent No. 1306176 are also unsatisfactory in terms of preservative performance.

[0006]

Therefore, the first object of the present invention is to improve the air oxidation stability of a developing solution containing a hydroquinone as a developing agent. The second purpose is to increase the stability of the developer while maintaining the concentration of the developer concentrate. The third purpose is to enhance the stability of the developer without promoting silver stain. The fourth object is to improve the stability of the developing solution to reduce the replenishing amount of the developing solution, reduce the pollution load, and improve the economic efficiency of the developing process.

[0007]

An object of the present invention is to provide a method for developing an exposed silver halide photographic light-sensitive material with a developer containing dihydroxybenzenes.

(Evaluation of Photographic Property) 488 using film A
An interference filter having a peak at nm and a continuous wedge were intervened to expose with a xenon flash light with an emission time of 10 ^-6 sec.
