Description

Description: TECHNICAL FIELD The present invention relates to a method for processing a silver halide photographic light-sensitive material having rapid processing suitability.

[Background of the Invention]

In recent years, the consumption of silver halide photographic materials has been steadily increasing. For this reason, the number of developed silver halide photographic materials has been increased, and it has been required to speed up the development processing, that is, to increase the processing amount within the same time.

The above tendency is also seen in the printing plate making field. That is,
Due to the rapid increase in the immediacy and the number of times of information, it is necessary to carry out printing and plate making operations in a short delivery time and in a larger amount. In order to satisfy the demands of the printing plate making industry, it is necessary to promote simplification of the printing process and to process the printing plate making film more quickly.

Therefore, the amount of gelatin has been reduced to shorten the drying time after the treatment. On the other hand, not only in processing but also in the exposure process, labor saving and speeding up are performed by automatic conveyance as seen in scanners and facsimile plotters, and a matting agent is added to the photosensitive material surface to improve film transportability Then, the surface roughness is increased.

However, when gelatin is reduced and a matting agent is used in a large amount, the concentration is reduced and pinholes are increased. For this improvement, technical studies such as the use of an amorphous matting agent and a monodispersed matting agent on the emulsion layer side have been conducted, but are insufficient, are capable of rapid processing, and have less occurrence of mat pinholes. A photosensitive material having good transportability and a satisfactory processing method therefor have not been obtained.

No. 64, JP-A-48-64933 and the like may be used.

In the present invention, the "development time" and the "fixing time" refer to the time from the time when the photosensitive material to be processed is immersed in the developing tank solution of the automatic developing machine to the time when the photosensitive material is immersed in the next fixing solution. It means the time from immersion to the next washing tank liquid (stabilizing liquid).

The term “washing time” refers to the time during which the sheet is immersed in the washing tank liquid. Further, the "drying time" is usually a drying zone in which hot air is blown at 35 ° C to 100 ° C and preferably 40 ° C to 80 ° C. Say.

The development temperature and time are about 25 ° C. to 50 ° C. for 15 seconds or less, preferably 30 ° C. to 40 ° C. for 6 seconds to 15 seconds.

The fixing solution is an aqueous solution containing a thiosulfate, and has a pH of 3.8 or more, preferably 4.2 to 5.5.

Examples of the fixing agent include sodium thiosulfate and ammonium thiosulfate. Thiosulfuric acid ions and ammonium ions are essential components, and ammonium thiosulfate is particularly preferable from the viewpoint of fixing speed. The amount of the fixing agent can be appropriately changed, and is generally about 0.1 to about 6 mol /.

The fixing solution may contain a water-soluble aluminum salt acting as a hardener, and examples thereof include aluminum chloride, ammonium sulfate, potassium alum and the like.

Tartaric acid, citric acid or their conductors can be used alone or in combination of two or more in the fixing solution. It is effective that these compounds contain 0.005 mol or more per fixing solution, particularly 0.01 mol / to 0.03 mol /.

Specifically, there are tartaric acid, potassium tartrate, sodium tartrate, potassium sodium tartrate, citric acid, sodium citrate, potassium citrate, lithium citrate, ammonium citrate and the like.

The fixing solution may optionally contain a preservative (eg, sulfite or bisulfite), a pH buffer (eg, acetic acid or nitric acid), a pH adjuster (eg, sulfuric acid), a chelating agent having a water softening property, The compounds described in JP-A-60-213562 can be included.

The fixing temperature and time are preferably from about 20 ° C to about 50 ° C for 6 seconds to 1 minute, more preferably from 30 to 40 ° C for 6 seconds to 30 seconds, and still more preferably from 30 ° C to 40 ° C for 6 seconds to 15 seconds. is there.

When the fixer concentrate is replenished to the automatic processor by the method of the present invention together with water for diluting the photosensitive material as it is processed, it is most preferable that the fixer concentrate is composed of the agent I. Is the same as in the case of the developer.

The fixing solution present solution can be stably present as the agent I at pH 4.5.
And more preferably pH 4.65 or more. pH4.5
If it is less than 30, the thiosulfate is decomposed and finally sulfided, especially when the fixing solution is left for many years until it is actually used. Therefore, in the range of pH 4.5 or more, the generation of sulfurous acid gas is small and the working environment is improved. The upper limit of the pH is not so severe, but if the fixing is carried out at an excessively high pH, the membrane pH is increased even after washing with water, and the membrane swells and the drying load is increased. In the case of a fixing solution that hardens using an aluminum salt, the pH is limited to a pH of 5.5 or less, which prevents precipitation and precipitation of the aluminum salt.

In the present invention, either the developing solution or the fixing solution may be a so-called working solution which does not require the above-mentioned dilution water (that is, replenishes as an undiluted solution).

The supply amount of each concentrated solution to the treatment tank solution and the mixing ratio with the dilution water can be variously changed depending on the composition of the concentrated solution.
The total amount of each of these developing solution and fixing solution is preferably 50 ml to 1500 ml per 1 m ² of the photosensitive material.

In the present invention, the light-sensitive material is subjected to washing or stabilization after the current solution and fixing.

Any method known in the art can be applied to the washing or stabilizing treatment, and water containing various additives known in the art can be used as the washing water or the stabilizing solution. The use of water which has been subjected to antifungal means in the washing water or stabilizing solution, not only the possible water saving processing of the photosensitive material 1 m ² per 3 less replenishing rate, automatic processor installed in the piping is not required Further, the number of stock tanks can be reduced. That is, the preparation dilution water and the washing water or the stabilizing solution for the developing solution and the fixing solution can be supplied from one common stock tank, so that the automatic developing machine can be made more compact.

When water that has been subjected to antifungal means is used in combination with washing water or a stabilizing solution, the occurrence of scale can be effectively prevented.
0 to 3, preferably 0 to 1, water saving treatment can be performed per ² pieces.

Here, the case where the replenishment amount is 0 means that no replenishment is performed except for appropriately reducing the amount of the washing water in the washing tank due to spontaneous evaporation or the like. This refers to the case where the processing method is performed.

As a method for reducing the amount of replenishment, a multi-stage countercurrent method (for example, two-stage, three-stage, etc.) has been known for a long time. If this multi-stage countercurrent method is applied to the present invention, the photosensitive material of the fixing solution is gradually processed in a clean direction, that is, the processing solution which is not contaminated with the fixing solution is successively contacted and processed. Washing is performed. According to this, unstable thiosulfate and the like are appropriately removed, the possibility of discoloration and fading is further reduced, and a more remarkable stabilizing effect is obtained. The amount of washing water is much smaller than before.

When washing with a small amount of washing water, it is more preferable to provide a squeeze roller washing tank described in Japanese Patent Application No. 60-172968.

Further, part or all of the overflow liquid from the washing or stabilizing bath, which is generated by replenishing the water subjected to the fungicide means to the washing or stabilizing bath according to the treatment, is disclosed in JP-A-60-2351.
As described in No. 33, it can also be used for a processing solution having a fixing ability, which is the preceding processing step. By doing so, it is more preferable because the stock water can be saved and the waste liquid can be reduced.

As the antifungal means, an ultraviolet irradiation method described in JP-A-60-263939, a method using a magnetic field described in JP-A-60-263940, and an ion-exchange resin described in JP-A-61-131632 are used. Method for making pure water, Japanese Patent Application No. 60-253807, 60-295894
