Description

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. In particular, it relates to a method of processing a silver halide photographic light-sensitive material suitable for rapid processing.

[0002]

2. Description of the Related Art As to the processing method of silver halide photographic light-sensitive materials, speeding up is required. This is strongly demanded, for example, in the field of medical X-ray photographic light-sensitive materials. For example, in large hospitals and the like where the number of X-ray films required for diagnosis per day is enormous, mechanization of agency work and high-speed diagnosis have recently been performed in order to reduce waiting time in order to avoid patient fatigue. . Therefore, shortening of the development processing time has been studied in the past few years, and processing for making the total processing time 45 seconds is becoming widespread, but there is a strong demand for further reduction.

When the processing time is shortened, the immersion time (developing time) in the developing solution is naturally shortened, so that the development may not be sufficiently performed. Therefore, development activation such as increasing the amount of the developing agent / auxiliary agent, increasing the pH, and adding a development accelerator has been carried out.

However, when the treatment is shortened to 30 seconds or less, the sensitivity can be achieved by the conventional method, but a satisfactory characteristic curve shape cannot be obtained (for example, γ reduction). However, problems such as lack of stability of sensitometry with respect to pH, dilution ratio from concentrated solution, uneven concentration, and the like were inevitably caused.

[0005]

SUMMARY OF THE INVENTION It is an object of the present invention to solve the above problems and provide a method of processing a silver halide photographic light-sensitive material which has good photographic characteristics and good stability even when subjected to rapid processing.

[0006]

SUMMARY OF THE INVENTION The above object of the present invention is to process a silver halide photographic light-sensitive material having at least one silver halide photographic emulsion layer by means of an automatic processor for carrying out at least development processing with a developing solution. In the method of processing a material, as a developer, (1) a dihydroxybenzene-based developing agent, (2) 1-phenyl-3-pyrazolidone-based auxiliary developing agent, (3) a compound represented by the general formula [1] and / or a general A compound containing the compound represented by the formula [2] is used (the general formulas [1] and [2] will be described later in detail),
And a processing time of Dry to Dry of 30 seconds or less, a method of processing a silver halide photographic light-sensitive material.

In the processing method of the silver halide photographic light-sensitive material of the present invention, the concentration of the buffer agent in the developer is preferably 0.5 mol / liter to 0.9 mol / liter.

In the processing method of the silver halide photographic light-sensitive material of the present invention, the coated silver amount of the light-sensitive material to be processed is preferably 3.90 g / m ² or less in terms of both sides.

In the processing method of the silver halide photographic light-sensitive material of the present invention, the replenishing amounts of the developing solution and the fixing solution are preferably 20 cc / quarter or less.

In the processing method of the silver halide photographic light-sensitive material of the present invention, it is preferable that the automatic developing machine performs each processing of development, fixing, washing and drying.

That is, as a result of earnest studies by the present inventor,
A compound represented by the general formula [1] and / or a compound represented by the general formula [2] (hereinafter sometimes referred to as the compound of the present invention) is contained in a developing solution, and rapid processing for 30 seconds or less is performed. By doing so, it was found that the above problems can be solved, and the present invention has been achieved.

Further, the concentration of the buffer agent in the developing solution is set to 0.
It is preferable that the amount is specified to 5 to 0.9 mol%, and it has been found that by adopting this mode, a preferable treatment having excellent running stability, particularly long-term stability can be performed.

Further, it has been found that a preferable processing with greatly improved processing variation can be carried out when the amount of silver attached to the light-sensitive material is 3.90 g / m ² or less in terms of both sides.

Further, a replenishment amount of 20 cc / quarter cutting or less has a great advantage of reducing the environmental load in the sense that the amount of waste liquid can be reduced, but since the residence time is extended by the reduction of the replenishment amount, the influence of air oxidation is exerted. However, it was found that the constitution of the present invention solves this problem and provides long-term stable processing performance.

The compound represented by the general formula [1] of the present invention may be an acid or a salt. A specific example will be shown later. Particularly preferred compounds are L-ascorbic acid, erythorbic acid and salts thereof. The amount added was 0.1 per liter of developer.
The amount is preferably 005 to 0.200 mol, particularly preferably 0.020 to 0.060 mol. If the amount is 0.200 mol or less per liter, a slight decrease in γ may occur and a sufficient characteristic curve may not be obtained. If the amount is more than 0.060 mol, there is a possibility that the processing variation will be large.

When this compound is dissolved in the concentrated part of the developing solution, it is preferable to add it to the acidic part rather than the alkaline part because of its storability.

Specific examples of the compound represented by the general formula [2] of the present invention are shown below, but a particularly preferred compound is N-hydroxysuccinimide or maleimide. The addition amount is preferably 0.005 mol to 0.40 mol, and more preferably 0.02 mol to 0.10 mol, per liter of the developing solution. When it is 0.005 mol or less per liter, running stability is slightly inferior, and when it is 0.40 mol or more, desensitization may occur.

Further, it is preferable to add both the compound represented by the general formula [1] and the compound represented by the general formula [2] according to the present invention.

In the practice of the present invention, the concentration of the buffer agent in the developing solution is preferably 0.40 mol to 0.90 mol, more preferably 0.50 to 0.65 mol.
If the amount added is less than this range, the running stability is not sufficient, and if the amount added exceeds this range, it is disadvantageous due to the relationship of the exudation property with respect to the volume of the concentrate.

The buffer agent is boric acid, bicarbonate, carbonate, phosphate, etc. in the alkaline range (pH 9.0 to 11.0).
Those having a buffering ability are preferably used, and boric acid and bicarbonate are more preferable.

The silver content of the light-sensitive material to be processed is preferably 3.9 g / m ² or less in terms of both sides. If it exceeds that, the effect of improving the process fluctuation due to the configuration of the present invention may not be sufficiently exhibited.

The replenishing amount of the developing solution and / or the fixing solution is 20.
cc / quarter size or less is preferable, more preferably 14 cc
/ It is cut into four or less pieces. 14 cc or less is preferable in order to reduce the cost of land treatment cost to the same level as or higher than the cost load of waste liquid treatment in the current situation where ocean dumping is possible. With the configuration of the present invention, it is possible to obtain sufficiently stable processing performance even with such low replenishment processing.

The processing time is Dry to Dry 30 seconds or less, preferably 25 seconds or less. By setting the time to 25 seconds, the processing time can be greatly shortened for the first time. Here, “Dry to Dry” means that a part of the photosensitive material to be processed (for example, a front end portion) is started to be processed by the processing liquid, and the processing is ended to dry the same portion (for example, dried and discharged). It is the time until (including so-called migration time).

The developing time (the time from the time when the liquid enters the developing solution to the moment when the liquid enters the fixing solution) is preferably 11 seconds to 5 seconds, and is automatically used in the steps of developing, fixing, washing with water (including stabilization) and drying. In the case of developing, the fixing time (the time from entering the fixing solution to the washing with water) is 4 seconds to 7 seconds, and the washing time (the time from entering the washing to the squeeze rack) is 2.5. It is preferable that the second to 5.5 seconds and the drying time (the time from the entry into the squeeze rack to the time when the squeeze rack enters the drying section) be 5 to 9 seconds.

With respect to the automatic developing machine, it is preferable to provide a cotton lacquer between the developing tank and the fixing tank and between the fixing tank and the water washing tank in order to drain the carry-in liquid. In addition, Watarilac having a cleaning mechanism is preferable.

The opening area ratio of the developing tank is preferably 0.035 or less in order to suppress the influence of air oxidation due to long-term processing.

In order to improve the drying property, it is preferable to use an infrared heater or a heat roller in the drying section.

When a sulfite is used in the developing solution, the amount thereof is generally preferably 0.40 mol / liter or more from the viewpoint of preservability, but from the viewpoint of silver sludge property and exuding property of the concentrated solution when kept cold. , 0.60 mol / liter or less is more preferable.

The developer and fixer concentrate are preferably enclosed in an integrated bottle. An automatic developing machine with a built-in automatic liquid preparation device is preferably used in order to save space and reduce the work load, and an integrated bottle is suitable for such an automatic developing machine in terms of workability. The number of developing solution concentration kit parts is preferably 2 parts or 1 part from an integral bottle.

As for the number of fixing solution concentrating kit parts, one solution is preferable because of the merits such as the workability of preparing the replenishing solution and the reduction of solution preparation errors.

The fixing solution may have aluminum removed because it is a solution of the concentrated solution which is caused by aluminum and is liquated out.

Conventionally, an acetic acid buffer has been generally used as a buffer agent for a fixing solution.
When a large amount of oxygen is added to suppress the increase, the acetic acid odor of the liquid is deteriorated, and the acetic acid odor of the treated film is deteriorated.As an alternative buffer agent, the material itself emits a weak odor, β-alanine. Preference is given to using succinic acid.
