Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automatic development processor for silver halide color photographic light-sensitive materials, and more particularly to an automatic development processor and processing method in which streaky uneven processing is prevented.

[0002]

2. Description of the Related Art The processing steps of a silver halide color photographic light-sensitive material consist of color development, desilvering, washing with water and / or stabilization. The desilvering process includes a bleaching process and a fixing process. When the bleaching step and the fixing step are performed separately, a bleaching solution and a fixing solution are used. When the bleaching step and the fixing step are carried out simultaneously, a bleach-fixing solution is used. It is also possible to use a combination of a bleaching solution and a bleach-fixing solution, a bleaching-fixing solution and a fixing solution, a bleaching solution, a bleaching-fixing solution and a fixing solution. The automatic developing machine for photographic light-sensitive materials has one processing solution tank and
Or, it has multiple tanks.

In recent years, the amount of waste liquid and the amount of replenishment have been actively reduced from the viewpoints of environmental protection and ease of handling by users. In order to reduce the amount of waste liquid and the amount of replenishment, a technical problem is a decrease in activity due to an increase in accumulated substances in the treatment liquid and a decrease in stability with an increase in the elapsed time of the treatment liquid. Color development, bleach-fixing and fixing are largely deteriorated by air oxidation, and many techniques for improving stability have been studied. Among them, the bleach-fixing solution has extremely poor stability because the preservative, which is a reducing agent, is mixed with the bleaching agent, which is an oxidizing agent, in addition to the air oxidation of the preservative. Improving the sex has been an extremely difficult task.

A technique which is particularly effective for improving the stability of a bleach-fixing solution is disclosed in Japanese Patent Laid-Open Publication Nos. 1-224762 and 1-22.
No. 31051, No. 1-230039, No. 2-9164
No. 3 is described. This is because a sulfinic acid compound is newly added as a preservative to improve the stability, and the stability of the bleach-fixing solution, which has been a problem, is remarkably improved. However, when the sulfinic acid compound was added to the bleach-fixing solution, a serious problem in practical use was discovered that streak-like processing unevenness was generated in the medium density range of the light-sensitive material (reflective density of about 0.5 to 1). . So far, there is no technology to solve the process unevenness caused by sulfinic acid compounds,
In order to realize low replenishment and low waste liquid, technological development for preventing the occurrence of processing unevenness has been strongly desired.

[0005]

SUMMARY OF THE INVENTION Therefore, a first object of the present invention is to prevent streak-like uneven processing defects which occur when a sulfinic acid compound is used. A second object is to reduce the amount of waste solution and the amount of replenishment of the bleach-fixing solution, to preserve the environment and to improve the handling convenience of the user.

After the running processing, the photosensitive material was not processed and the processing temperature was adjusted to 10 hours / day for 3 weeks. The decrease in the liquid level due to evaporation was corrected by adding water every day. The above coated sample which had been unexposed and gray-exposed to a density of about 0.5 after 3 weeks was treated, and the yellow minimum density (YD
