DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for taking out a processing agent for a photosensitive material, and more particularly to a method for taking out a processing agent for a photosensitive material which is excellent in handleability and is preferable in terms of safety and health.

[0002]

2. Description of the Related Art Conventionally, a processing agent for a silver halide photographic light-sensitive material such as a color film, a color paper, a lith film and an X-ray film, and a non-silver salt light-sensitive material for printing such as a PS plate is, for example, a polyethylene bottle. A hard container such as hard polybin or a soft container such as “Cubitener” is used.

[0003] The treatment agent contained in these containers may be a liquid agent or a solid agent, but in any case, it is not preferable to adhere to the hand. In particular, since the developer is strongly alkaline, special attention is required.

[0004] However, the processing agent often adheres to hands when the contents of the processing agent are charged from these containers into an automatic developing machine.

[0005] In the case of hard polybins and the like, a liquid mixing mixer,
In some cases, preparation is performed using a so-called “chemical mixer”. However, even in this case, the internal treating agent may adhere to the inner wall of the container and may not be sufficiently removed. In particular, it is remarkable in a solid developer such as a processing agent having a high viscosity or a granule.
It is expected that the treatment agent remaining inside the container is not preferable in terms of disposal and also causes a concentration variation of the charged solution, which may cause a fluctuation in treatment performance.

[0006] On the other hand, plastic waste has become a major social problem from the viewpoint of environmental protection. In particular, polyvin is difficult to dismantle, has a large volume, and has storage and transportation problems.

Attention has been paid to flexible soft containers instead of polyvins. Specific product names include “Cubitener”, “Show Repack”, “Chapak”, “Doipack”, and the like. These are containers formed by processing a relatively thin resin into a square shape, a standing pouch shape, or the like. In particular, standing pouch-type containers have the advantage that when used, they have a very small volume when they are used and are easy to dispose of.

When a processing agent is filled in a standing pouch-type container, it is common practice to take out the processing agent by cutting the upper part of the container obliquely with scissors at the time of use. However, in this method, a treatment agent is attached to hands or the treatment agent adheres to scissors, causing rust. Further, the standing pouch has a problem in disposal because the treating agent tends to remain in the container as compared with the polybin. Furthermore, when the treating agent is a powdery or granular solid agent, the treating agent tends to remain in the container. It is considered that this is because the standing pouch is originally of a type in which two flat resin films are opposed to each other, so that when the content decreases, the treating agent is sandwiched between the resin films. Thus, although the standing pouch has the merit of disposal, there are some problems in use.

[0009]

SUMMARY OF THE INVENTION It is an object of the present invention to provide a processing agent which can be easily taken out of the processing agent without soiling the hands, reduce the amount of the remaining processing agent in the container, and reduce the fluctuation performance of the processing agent.

At the time of disposal, a bulky and foldable container is preferable, and a standing pouch type can be suitably used. Further, since the bottom of the container is provided with holes or cuts, it is preferable to make the film thinner or weaker than the side surfaces. If necessary, an outlet may be provided at the bottom in advance, and a cap may be attached. The outlet may be sealed with an aluminum foil or the like to prevent the treatment agent from leaking, and may have a structure in which a hole is easily formed. Moreover, you may perforate from a cap.

FIG. 1 shows a specific example of the form of the container used in the present invention.
(A) to FIG. 1 (e) are shown.

FIG. 1 (a) is a square-shaped flexible plastic container which is heat-sealed on its upper and side sides.

FIG. 1B shows a type having an outlet in FIG. 1, which is commercially available under the trade name "Cheer Pack".

FIG. 1C shows a hard polybin.

FIG. 1D shows a standing pouch-type flexible container commercially available under the trade name "Doipack".

FIG. 1 (e) shows the standing pouch of FIG. 1 (b) with an outlet at the bottom.

In the present invention, other types of containers such as a plastic bag, a milk carton, and a cubine can be used.

In the take-out method of the present invention, the take-out port is opened in the container filled with the treating agent at the time of use.
The take-out port is preferably provided at the bottom of the container for ease of taking out the treatment agent, but may be provided at the side or top of the container in some cases. When the take-out port is provided at the upper part, it is troublesome to take out the liquid material by suction, but when supplying the cleaning water, it is not particularly necessary to apply a water pressure and the cleaning is easy. There are two ways to open the outlet in the container: a method in which a processing agent container is inserted into a piercing blade to make a hole, a method in which the blade is moved and cut open, or a method in which an outlet is provided in the container in advance and the outlet is attached. There is a method of providing an outlet by peeling off a seal made of aluminum foil or the like.

The size of the outlet may be relatively small in the case of a liquid agent, but is preferably increased in the case of a solid agent.

The method of discharging the treating agent from the outlet is as follows.
The method of dropping and discharging by gravity is advantageous, but it may be discharged by suction with a pump or the like.

After or after discharging the treating agent from the outlet, a predetermined amount of washing water is sprayed from the washing water supply nozzle to wash the inside of the container.

The washed washing water is supplied to a processing liquid tank provided below the container.

The washing water supply nozzle is preferably integrated with the drilling blade, and has a specific structure as shown in FIG. It is preferable that the pressure of the washing water is increased to efficiently wash the inside of the container, and that warm water is used.

The water pressure of the washing water is increased particularly in the case of a standing pouch type container, and is preferably in the range of 0.3 to 5 kg / cm ² .

The temperature of the washing water is 27-50 ° C., preferably 35 ° C.
~ 45 ° C. If the washing water is lower than 27 ° C, the cleaning effect of the liquid or powder remaining in the container is weak, and if it is higher than 50 ° C, the cleaning effect is good, but depending on the material of the container, the material of the container may be dissolved. If the container is deformed or high-temperature washing water is used, there is a problem in handling safety.

The timing of supplying the cleaning water is preferably such that, when the processing agent filled is a liquid agent, the cleaning water is supplied after the liquid agent is taken out. At the same time, it is preferable to take out the solidifying agent while dissolving it with washing water.

The processing agent for a photosensitive material used in the present invention is a processing agent for a silver halide photographic material and a non-silver salt photosensitive material for a printing plate such as a PS plate, and can be used for both a liquid agent and a solidifying agent. However, it is particularly effective for solidifying agents.

Processing agents for silver halide photographic materials include black-and-white developers, color developers, fixers, bleach-fixers,
A liquid agent such as a bleaching solution or a stabilizing solution instead of washing, or a solidifying agent such as a powder or granule thereof can be applied.

As a processing agent for a non-silver salt photosensitive material for a printing plate such as a PS plate, a developing solution, a developing replenisher, a rinsing solution, a gum solution, or a solidifying agent such as a powder or granule thereof may be used. Can be.

The black-and-white developing solution for a silver halide photographic light-sensitive material contains at least one black-and-white developing agent selected from hydroquinones, 1-phenyl-3-pyrazolidones and para-aminophenols.

The color developing agents used in the color developing solution are disclosed in Japanese Patent Application Nos. 3-264896, 3-272952, 4-81883 and 4-321.
Compounds described in No. 54 and the like are used.

EXAMPLES Examples of the present invention will be described below, but the present invention is not limited to these examples. Example 1 The film configuration was such that low-density polyethylene (150
μ) / Saran coat PET (12μ) / Nylon (15μ)
1A was filled with the following X-ray developer kits A, B, and C manufactured by Konica Corporation.

Part (A) potassium hydroxide 230 g potassium sulfite 610 g sodium bicarbonate 120 g diethylenetetraminepentaacetic acid 28 g 5-methylbenzotriazole 0.5 g 1-phenyl-5-mercaptotetrazole 0.2 g hydroquinone 300 g Part (B) Triethylene glycol 200 g 5-Nitroindazole 1 g 1-Phenyl-3-pyrazolidone 13 g Glacial acetic acid 100 g Add water 300 ml Part (C) Glutaraldehyde bisulfite 130 g Add water 250 ml The bottom of the filled container of the kit was attached to the perforation nozzles 1, 2, and 3 of the liquid preparation device of FIG. 3, and the processing liquid therein was discharged. Thereafter, from the washing nozzle integrated with the perforated nozzle, an amount of washing water corresponding to about 3.3 times the total capacity of the kit was jetted to wash the inside of the container. The discharged washing water was used as dilution water for the treatment liquid. The processing agent used as the used solution was sufficiently mixed by the stirrer 4 and the developing replenisher was sent to the processor by the liquid sending pump 5.

At the start of development, the starter is adjusted,
Used at the start.

Glacial acetic acid 16 g Potassium bromide 19.0 g Water was added to 1.0 liter Wash water was supplied into the container at a flow rate of 20 l / min using tap water preliminarily adjusted to 40 ° C. A nozzle having an inner diameter of 3 mm was used as a washing water supply nozzle.

The fixing solution used had the following composition.

Ammonium thiosulfate 140 g Sodium sulfite anhydride 8.8 g Boric acid 7.0 g Sodium acetate trihydrate 20 g Aluminum sulfate 18 hydrate 18 g Sulfuric acid 8 g Glacial acetic acid 5.5 g Make up to 1 liter with water. <Processing Method> At the start of development, 20 ml of the above-mentioned starter was added per liter of the developing solution as a starter, and the developing solution was processed using an automatic developing machine SRX-501 (manufactured by Konica Corporation). The amount of washing water at this time was ² per m2 of film.
At 1 / m ² , the developer replenishment rate was 250 ml / m ² . The replenishment rate of the fixing solution was 360 ml / m ² .

The film was made using Konica SR-G.
Post exposure processing.

As described above, when the X-ray film was developed, it was only necessary to set the developer kit, and the development could be easily performed for a long period of time. Since the container for the developer was automatically washed, the liquid remained in the container to some extent, but was almost like water, so that it was harmless even if it adhered to hands. The treatment agent container was foldable, and the disposal volume was smaller than that of the case of polybin, and the disposability was excellent. In addition, there was no performance fluctuation due to the residual processing solution in the container which tends to be a problem in such a flexible container.

Example 2 A color developing replenisher kit (10 liter kit) for a color paper having the following part configuration was loaded from the inside with PE (100 liter).
μ) / Nylon (2μ) / Polyurethane (3μ) / PE
A T (10μ) film was used to fill a bag made into the shape shown in FIG. 1D, and the opening was heat-sealed to obtain a container. This was set in the liquid preparation device of FIG.

Color developing replenisher for color paper Part A Pure water Approx. 100 g Triethanolamine 145 g N, N-diethylhydroxylamine 70 g Fluorescent brightener 15 g Diethylene glycol 145 g Pure water was added to make up to 0.4 liter.

Part B About 300 g of pure water 4.3 g of potassium sulfite N-ethyl-N-β-methanesulfonamidoethyl-3-methyl-4-aminoaniline sulfate 65 g Pure water was added to make up to 0.4 liter.

Part C Pure water About 400 g Potassium carbonate 350 g Potassium bromide 0.1 g Potassium chloride 3 g Ethylenediaminetetraacetic acid 15 g Catechol-3,5-disulfonate disodium salt 15 g 1-Hydroxyethylidene-1,1-disulfonic acid 15 g Pure water And finished to 0.6 liters.

When the starting solution is used, 0.01% potassium bromide per liter of the starting solution is added to a replenisher of 70% of the starting solution to be prepared.
5 g, 2.3 g of potassium chloride and 2.5 g of 50% sulfuric acid are added, and water is added to finish to 100%.

The starting liquid was charged into a Konica CL-PP1701 printer processor, and wedge exposure was performed on a Konica color paper type QA-A5 by a conventional method.
The running process was performed while replenishing the solution from the developing replenisher tank 9 shown in FIG.

The bleach-fixer / stabilizer was Konica K-20P2.
R-01 and K-20P3R-01 were used.

The container filled with the processing solution is pierced by the perforation blades 6, 7, and 8 in FIG. 4 so that a hole is formed in the container, and the liquid inside falls down and enters the developing replenisher tank. Thereafter, the cleaning liquid is jetted from the cleaning nozzle to clean the container. At this time, pure water heated to 40 ° C. was used. The total amount of washing water was adjusted to 8.6 l. Also,
Compressed air was simultaneously sent into the container. By doing so, the dent-shaped container swelled, and the cleaning effect was improved. (Using the washing nozzle of FIG. 4 (h). A perforation nozzle having the shape as shown in FIG. 4 (g) can also be used.) When the developing replenisher is charged, it can be set without soiling the hands, and the processing solution in the container is sufficiently removed. Can be put into the processing liquid tank
A stable development replenisher could always be prepared, and as a result, the quality of the processed paper was stable. Further, the container for the developing replenisher had little liquid remaining therein, but was almost close to water and had no problem even if it adhered to hands. Furthermore, this container can be folded at the time of disposal, and was excellent in disposability.

Example 3 A positive PS plate SLP-N (manufactured by Konica Corporation) was image-exposed. On the other hand, 0.76 kg of potassium silicate and 0.31 kg of potassium hydroxide, each consisting of 26% by weight of SiO _{2 and} 13.5% by weight of K ₂ O, and pure water
A development replenisher for positive PS plate consisting of 0.31 kg was granulated by a stirring granulator. 0.6 kg of a developer was obtained.

This granule developer was filled in a standing pouch type container (A) shown in FIG. 1D having the following layer constitution, and heat-sealed.

Container (A) From inside: 75 μl of polyethylene / 12 μl of EVAL / Alμ / 15 μL of PET Separately, a rinsing liquid SRW-1 (manufactured by Konica Corporation) was powdered with a spray dryer, and the standing pouch type container (B) shown in FIG. ) And sealed.

Container (B) From inside: polyethylene / nylon 6.10 / Al / polyethylene, total thickness 250 μm.

When the above powdery PS plate treating agent was used, the upper portion was cut off with scissors as shown in FIG. 5 (k), and manually charged into the respective treating solution tanks. However, at this time, the dust still remains on the container wall. This container is turned upside down and put on the washing nozzle of the apparatus of FIG. 5 (i), and a pump for supplying washing water is operated to supply a certain amount of washing water into the container.
The container was washed. This washing water falls down, enters the processing liquid tank, and is used as dilution water. Using a magnet pump that sends 10 liters of water for development replenisher per minute,
4 L of washing water was supplied from a washing water supply nozzle having five nozzle holes having a hole diameter of 1 mm to wash the inside of the container. This 4 l of washing water enters the lower developing replenisher tank and is diluted with water (dissolved water).
Becomes The washing water used at this time was heated by a heater provided in the washing tank and the temperature was adjusted to 35 ° C.

The granule developer and the rest of the powder gum in the container were not visually observed. The pH of the prepared development replenisher was 13.80 at 25 ° C., which was a standard pH value. When the replenisher was used for replenishing the automatic developing machine and the running process was performed for a long period of time, the finish of the PS plate was stable.

Further, the rinsing liquid was normally replenished, and no stain was generated during printing.

Comparative Example 1 In Example 3, the upper part of the standing pouch type container of the solid processing agent was cut with scissors, and the powder processing agent was manually charged.
This container was discarded without washing, and the same amount of water as the washing water of Example 3 was added to the treatment liquid tank to prepare a treatment agent. Other operations were performed in the same manner as in Example 3. As a result, a considerable amount of solid processing agent still remained in the processing agent container. (FIG. 5 (l)) In particular, there was little clearance at the side portion of the container, a force for flattening the container worked, and the powder treatment agent was likely to remain. When the container was shaken in order to sufficiently remove the powder from the container, the powder scattered and soiled the apparatus and floor. However, solids remained in the container.

The prepared developer replenisher had a pH at 25 ° C. of 13.65 lower than the standard because the powder processing agent was less than the predetermined amount. As a result, the developability of the PS plate was reduced, halftone dots in the shadow portion of the printed matter were easily broken, and the reproducibility of the shadow portion was deteriorated.

On the other hand, the replenishment of the rinsing liquid tends to be insufficient, and the erased portion of the plate becomes stained during printing.

Comparative Example 2 FIG. 4 (f) was obtained by filling the container of FIG. 1 (d) with the color developing replenisher kit for color paper in Example 2.
Without using the above device, the upper corner of the container was cut with scissors, and the processing solution was manually poured into the developing replenisher tank.

Thereafter, an experiment was carried out in the same manner as in Example 2 except that predetermined dilution water was added to the developing replenisher tank, stirred, and used as a developing replenisher.

As a result, liquid remained in the processing agent container, the amount of which was larger than that in the case of using the polyvin container, the used liquid component of the developing replenisher became thinner than a predetermined amount, and the tendency of the developing property to decrease was observed.

Further, when the standing pouch type treating agent container is opened, it is not possible to prevent the liquid from dripping, and there is a problem that the liquid remaining in the treating agent container adheres to hands and clothes, and a problem of soiling the floor. In addition, there was a problem that scissors used when opening the treatment agent container were rusted, which was not a preferable operation result.

[0079]

According to the method for removing a treating agent of the present invention, the treating agent can be easily removed without soiling the hands, the amount of the remaining treating agent in the treating agent container can be reduced, and the fluctuation performance of the treating agent can be reduced. But with excellent processing performance.
