DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. 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 method for processing a silver halide photographic light-sensitive material which does not delay fixing even when the replenishment is reduced. is there.

[0002]

2. Description of the Related Art Generally, processing of a silver halide color photographic light-sensitive material comprises a color developing process and a silver removing process. Silver generated by development is oxidized by a bleaching agent and then dissolved by a fixing agent. A ferric (III) ion complex salt (for example, aminopolycarboxylic acid-iron (III) complex salt) is mainly used as a bleaching agent, and a thiosulfate is generally used as a fixing agent.

On the other hand, the processing of a black-and-white photographic light-sensitive material comprises a development step and a step of removing unexposed silver halide, and unlike the processing of a color photographic light-sensitive material, fixing processing is performed without a bleaching step after development. Also in this case, thiosulfate is usually used as a fixing agent.

[0004] In recent years, reduction of the replenisher amount of a photographic processing solution has been actively studied. The same applies to a bath having a fixing ability. However, silver ions and halogen ions (eg, iodine ions, bromine ions, and chloride ions) that accumulate in the running fatigue fluid as the replenishment rate decreases.
It is a major problem that the amount of the toner increases and the progress of fixing becomes slower, and there is a demand for a liquid composition that does not delay fixing even when the replenishment is reduced. In addition, when the replenishment is reduced, the residence time of the liquid is extended, so that the liquid stability also becomes a problem. Particularly, thiosulfate, which is widely used as a fixing agent, has a problem of sulfurization, and therefore, improvement of this point is highly desired.

In order to improve this point, thiocyanate ions (eg, ammonium thiocyanate, sodium thiocyanate) have conventionally been added to a bath having a fixing ability, but the fixing delay has not been sufficiently improved. In addition, a good material has been desired since there is concern about the effect of thiocyanate ions on the environment.

[0006]

The color developing replenisher contains compounds contained in the color developing solution. The role of the color developing replenisher is to control the concentration of the compound eluted from the photosensitive material by the processing of the photosensitive material or the replenishment of the compound to the color developing solution, which is reduced by deterioration over time in an automatic processor, and vice versa. In this case, the developing performance is kept constant. Therefore, the former compound has a higher concentration than the color developing tank solution,
Also, the latter compound has a low concentration. The former compound is a color developing agent or a preservative, and the replenisher contains 1.1 to 2 times the amount of the tank solution. The latter compound is a development inhibitor typified by a halide (for example, potassium bromide).
0.6 times. The halide concentration in the replenisher is usually 0.006 mol / l or less, but it is necessary to reduce the concentration as the replenishment becomes lower, and the halide may not be contained at all. Compounds that hardly change in concentration due to processing or aging are usually contained at approximately the same concentration as the color developing tank solution. Examples of this are chelating agents and buffers. Further, the pH of the replenisher for color development is 0.05 to 0.
Increase by about 5 This difference in pH also needs to increase with decreasing replenishment. The replenishment amount of the color developing solution is 3000 ml or less per 1 m ² of the light-sensitive material.

The processing time is suitably from 20 seconds to 5 minutes, preferably from 30 seconds to 3 minutes and 20 seconds, and more preferably from 1 minute to 2 minutes and 30 seconds. Further, the color developing bath may be divided into two or more baths as necessary, and a color developing replenisher may be replenished from the first or last bath to shorten the developing time and further reduce the replenishing amount.

The processing method of the present invention can be preferably used for color reversal processing. In the reversal process, after the black and white development, the reversal process is performed as necessary, and then the color development is performed. The black-and-white developing solution used at this time is a so-called black-and-white first developing solution which is generally used in a reversal process of a color photosensitive material, and is a black-and-white developing solution used in a processing solution of a black-and-white silver halide photosensitive material. Various well-known additives used in addition to the liquid can be contained.

For example, opening area (cm ² )
Is divided by the volume of the developing solution (cm ³ ), and the opening ratio is preferably 0.01 (cm ⁻¹ ) or less.
005 or less is more preferable.

The developer can be regenerated and used.
Regeneration of the developing solution means that the used developing solution is subjected to anion exchange resin or electrodialysis, or the activity of the developing solution is increased by adding a processing chemical called a regenerating agent, and used again as a processing solution. . In this case, the regeneration rate (the ratio of the overflow solution in the replenisher) is preferably 50% or more, particularly preferably 70% or more. As processing using developer regeneration, after regenerating the overflow solution of the developer,
Use as replenisher. As a regeneration method, it is preferable to use an anion exchange resin. Regarding the particularly preferred composition of the anion exchange resin and the method of regenerating the resin, see DIAION MANUAL (I) (198)

However, it is particularly preferably 50 ml to 1500 ml. The treatment temperature of the conditioning bath is preferably from 20C to 50C, and particularly preferably from 30C to 40C.

It is preferable to use a method in which the overflow solution in the washing step or the stabilization step is flowed into a bath having a fixing ability, which is a pre-bath, since the amount of waste liquid can be reduced. In the processing, not only the bleaching solution, the bleach-fixing solution, and the fixing solution but also other processing solutions (for example, a color developing solution, washing water, and a stabilizing solution) require an appropriate amount of water or a correction amount to correct the concentration due to evaporation. It is preferable to replenish the solution or the processing replenisher.

In a multilayer silver halide color photographic light-sensitive material, the arrangement of unit photosensitive layers is generally such that a red-sensitive layer, a green color-sensitive layer Layer and a blue-sensitive layer in this order.
However, the order of installation may be reversed depending on the purpose, or the order of installation may be such that different color-sensitive layers are sandwiched between the same color-sensitive layers. Non-photosensitive layers such as various intermediate layers may be provided between the silver halide photosensitive layers and as the uppermost layer and the lowermost layer.

As described in West German Patent 1,121,470 or British Patent 923,045, a plurality of silver halide emulsion layers constituting each unit light-sensitive layer may be composed of a high-sensitivity emulsion layer and a low-sensitivity emulsion layer. A two-layer structure of layers can be preferably used. Usually, it is preferable to arrange them so that the light sensitivity decreases sequentially toward the support, and a non-photosensitive layer may be provided between the respective halogen emulsion layers. Also, JP-A-57-112751, JP-A-62-200350,
As described in JP-A-62-206541 and JP-A-62-206543, a low-sensitivity emulsion layer may be provided on the side remote from the support, and a high-sensitivity emulsion layer may be provided on the side close to the support.

Alternatively, they can be installed in the order of BH / BL / GL / GH / RH / RL, or in the order of BH / BL / GH / GL / RL / RH. Further, as described in JP-B-55-34932, the layers may be arranged in the order of blue-sensitive layer / GH / RH / GL / RL from the side farthest from the support. JP-A-56-25738 and JP-A-62-63.
As described in JP-A-936, the blue-sensitive layer / GL / RL / GH / RH may be arranged in this order from the farthest side from the support. In addition, Japanese Patent Publication No. 49-15495
The upper layer is the most sensitive silver halide emulsion layer, the middle layer is the lower sensitive silver halide emulsion layer, and the lower layer is less sensitive than the middle layer as described in An example is an arrangement in which a silver emulsion layer is disposed, and the sensitivity is sequentially lowered toward the support, and the sensitivity is sequentially reduced to three layers having different sensitivities. Even when such three layers having different sensitivities are used, as described in JP-A-59-202264, the medium-sensitive emulsion layer / They may be arranged in the order of high-speed emulsion layer / low-speed emulsion layer. As described above, various layer configurations and arrangements can be selected according to the purpose of each photosensitive material.

The photosensitive material was stored under conditions of 5 ° C. and 50% RH for 7 days after the preparation, first, the total thickness of the photosensitive material was measured, and then, after removing the coating layer on the support, the thickness was measured again. The difference is used to determine the thickness of the entire coating layer excluding the support of the photosensitive material. The thickness is measured, for example, by a film thickness measuring device (Anritus Electric Co.
Ltd., K-402B Stand.). The removal of the coating layer on the support can be performed using an aqueous solution of sodium hypochlorite. Further, a photograph of a cross section of the above-mentioned photosensitive material can be taken using a scanning electron microscope (preferably at a magnification of 3,000 or more), and the total thickness on the support can be measured.

100] is preferably 50 to 200%, and 70 to 150%
Is more preferred. If the swelling ratio deviates from the above value, the residual amount of the color developing agent increases, and adversely affects photographic performance, image quality such as desilvering properties, and film properties such as film strength.

Further, the film swelling speed of the light-sensitive material in the present invention is defined as a saturated swelling film thickness which is 90% of the maximum swelling film thickness reached when processing in a color developing solution (38 ° C., 3 minutes 15 seconds). When the time required to reach this 1/2 film thickness is defined as the swelling speed T1 / 2, it is preferable that T1 / 2 is 15 seconds or less. More preferably, it is 9 seconds or less.
