Abstract

PURPOSE:To form the processing soln. from a little part soln. and to supply the soln. through a circulating mechanism by parting the replenishing soln. into two kinds of processing solns. and adding the second-part processing soln. to the vessel of the first-part processing soln. CONSTITUTION:The replenishing soln. is parted into a first-part processing soln. and a second-part processing soln., and the first-part processing soln. is charged in the vessel of enough volume to contain the starting mother liquor. The second-part processing soln. is added to the first-part processing soln. to obtain a replenishing soln. A third-part processing soln. is further added to the replenishing soln. to obtain the starting mother liquor. The first-part processing soln. contains the composition except the color developing agent, the second-part processing soln. contains the color developing agent, and the third-part processing soln. contains at least an inhibitor. As a result, the number of the parts of the processing soln. to be supplied is reduced, and the replenishing soln. and starting mother liquor are prepared only with the processing soln. supplied.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for supplying a processing solution for silver halide color photographic light-sensitive materials, and more specifically, a processing solution is prepared by using only the processing solution supplied. The present invention relates to a method for supplying a processing solution for a silver halide color photographic light-sensitive material to obtain a solution.

[0002]

2. Description of the Related Art Processing of a silver halide color photographic light-sensitive material is performed by subjecting the light-sensitive material to photographic exposure, followed by color development processing, bleaching processing, fixing processing (bleach-fixing processing), water washing processing (washing processing), stabilization processing and drying processing. In addition to the above, there are other processing steps added in order to stably use each processing solution, to increase the physical strength of the processed light-sensitive material, and to increase the stability.

In the processing of silver halide color photographic light-sensitive materials, replenishment is generally carried out in order to keep the quality thereof constant, and the replenishing role is lost. It is in the recovery of the activity of the liquid.

In order to facilitate the processing of the silver halide color photographic light-sensitive material, the processing agent used in the processing is supplied in the form of a liquid, and the processing solution can be obtained only by diluting with water. .. However, although easy to use,
The supply liquid has various states, and is supplied in many parts.

When processing a silver halide color photographic light-sensitive material with a replenishing solution, a replenishing solution is necessary in addition to a starting mother liquor (also called a new solution). The starting mother liquor is used at the start of processing and when all the solutions are renewed. Only necessary, replenisher is sufficient for all other cases. Therefore, it is not preferable to separately supply the two types of treatment liquids, that is, the starting mother liquor and the replenishment liquid, from the viewpoints of manufacturing the treatment agent and simplifying the stock of the treatment agent. The method of preparing the starting mother liquor by these combinations has been generalized.

In recent years, the processing of silver halide color photographic light-sensitive materials is progressing with mechanization of processing and simplification of processing, and with the spread of small automatic processors, a small space is used.
Processing is done in many places. Since the water washing process, which was indispensable for photo processing, was replaced by a processing agent due to technological advances, there was no need for water supply facilities for water supply, and the amount of replenishment was also small, so it was discharged after use. The amount of processing liquid used also decreases,
It is now possible to collect the waste liquid after use in a container, eliminating the need for a facility for draining water, and installing an automatic processor anywhere.

[0007]

It is considerable to prepare a replenisher using a processing solution supplied in a number of parts and to prepare a starting mother liquor using a part of the replenisher. Since the water washing equipment is not required because the washing process is replaced by treatment with a treating agent, it is no longer necessary to use water equipment on the automatic processor side, making it more inconvenient to use water. Therefore, a treatment liquid that can be used as it is, which facilitates the preparation of However, the processing liquid that can be used as it is has a problem in stability, and it changes within the distribution period of the product and cannot be used in good condition.

[0008]

An object of the present invention is to supply a stable processing liquid throughout the distribution period of a product,
Another object is to reduce the number of parts of the processing solution supplied, and yet another object is to prepare the replenisher solution and the starting mother liquor with only the supplied processing solution.

As a method for achieving the above-mentioned object, in a treatment liquid composed of a plurality of treatment liquid parts, a replenisher liquid is obtained by adding the other treatment liquid part to one treatment liquid part, and further another treatment liquid. The purpose was achieved by adding the parts to obtain the starting mother liquor, 2 parts to obtain the replenisher and 1 part to obtain the starting mother liquor, and to obtain all treatment liquids without using water.

The treatment liquid of the first part is stored and supplied in a container capable of storing the starting mother liquor, and the treatment liquid of the second part is stored in the first portion.
A replenisher is obtained by adding it to the treatment liquid of the part, a starting mother liquor is obtained by further adding the treatment liquid of the third part to the replenisher, and the treatment liquid of the first part is stored and supplied in a container capable of storing the amount of the replenisher. However, the treatment liquid of the second part is added to the treatment liquid of the first part to obtain a replenisher liquid, and all treatment liquids can be obtained without using water or a container.
