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 light-sensitive material, and more particularly to a method for taking out a processing agent for a light-sensitive material which is excellent in handleability and is preferable in terms of safety and hygiene.

[0002]

2. Description of the Related Art Conventionally, processing agents for silver halide photographic light-sensitive materials such as color films, color papers, squirrel films and X-ray films and non-silver salt light-sensitive materials for printing such as PS plates are, for example, polyethylene bottles. Such a rigid polybin or a soft container such as a "cube tenor" is used.

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 it to the hand. In particular, the developer is strongly alkaline, so special care is required.

However, when the contents of the processing agent are charged into the automatic developing machine from these containers, the processing agent often adheres to the hand.

For hard polybin, etc., a liquid preparation mixer,
There is also a case where the so-called "chemical mixer" is used for preparation. However, even in this case, the treatment agent inside may adhere to the inner wall of the container and may not be sufficiently taken out. Especially, it is remarkable in a processing agent having a high viscosity and a solid developer such as granules.
It is expected that the treatment agent remains inside the container, which is not preferable in terms of disposal and causes variations in the concentration of the charged liquid, which may cause fluctuations in the treatment performance.

On the other hand, plastic waste has become a major social problem from the viewpoint of environmental protection. In particular, polybin is difficult to disassemble, has a large volume, and has problems in storage and transportation.

In place of these polybins, flexible and soft containers are drawing attention. Specific product names include "Cubitener", "Shoripak", "Charpack", "Doipack", etc. These are containers obtained by processing a relatively thin resin into a square type or a standing pouch type. In particular, a standing pouch-type container has an advantage that it is easy to dispose of when it is a used container because it has a very small volume because it falls.

When a standing pouch type container is filled with a treating agent, a method is generally used in which the treating agent is taken out by obliquely cutting the upper part of the container with scissors. However, in this method, the treatment agent is attached to the hand or the treatment agent adheres to the scissors, which causes rust. In addition, the standing pouch has a problem in disposal because the treating agent is more likely to remain in the container than polybin. Further, when the treating agent is a powdery or granular solidifying agent, the treating agent is likely to remain in the container. It is considered that this is because the standing pouch is a type in which two resin films, which are originally flat, are opposed to each other, and thus the treating agent is sandwiched between the resin films when the content decreases. As described above, the standing pouch has a merit of discardability, but has some problems in use.

[0009]

It is an object of the present invention to easily remove the treating agent without soiling the hands when using the treating agent, reduce the amount of the residual treating agent in the container, and reduce the fluctuation performance of the treating agent. It is to provide a method of taking out.

Still another object of the present invention is to provide a method for taking out a treating agent which has improved practical problems of the treating agent container having excellent disposability.

[0011]

The above object of the present invention is achieved by the following configurations.

(1) A photosensitive material having a device for cleaning the inside of the container after or while taking out the processing agent from a container filled with the processing agent for the photosensitive material to a processing solution tank in a developing machine for the photosensitive material. Is a processing device for a container, wherein the container is made of synthetic resin, and the thickness of the wall surface of the container is 30 to 500.

A container filled with the processing agent for the light-sensitive material of the present invention is a polybin made of hard polyethylene or polypropylene or the like, a soft cubator mainly composed of low density polyethylene, a cheer pack with a tape, a standing pouch type doy pack, etc. Various containers are used,
In the present invention, it is particularly effective when applied to a standing pouch type container.

In addition, as a usable container, a container obtained by laminating polyethylene on paper used for sake, milk, juice and the like can also be used.

The treatment agent container preferably used in the present invention is a container whose main constituent material is a flexible synthetic resin material, and may be a film made of a single material, but in the case of imparting gas barrier property or hot melt property, A multilayer structure is preferable.

Examples of synthetic resin materials include polyethylene,
Examples include polypropylene, polyvinyl chloride, polyvinyl acetate, nylon, polyvinylidene chloride polystyrene, polycarbonate, vinylon, EVAL, polyethylene terephthalate (PET), polyester, rubber hydrochloride, acrylonitrile butadiene copolymer, and epoxy-phosphate resin.

These are usually laminated and adhered to the film, but may be applied as a coating layer.

Further, it is more preferable to use various gas barrier films, for example, aluminum foil, aluminum vapor deposition synthetic resin or silica vapor deposition synthetic resin is used for the above film.

The thickness of the film film of the container is preferably 30 to 500 μm, more preferably 50 to 300 μm.

Examples of the one-layer polymer resin film satisfying the conditions of the present invention include (1) polyethylene terephthalate (PET) having a thickness of 0.1 mm or more, and (2) acrylonitrybutaciene having a thickness of 0.3 mm or more. Examples thereof include copolymers and (3) hydrochloric acid rubber having a thickness of 0.1 mm or more. Among them, polyethylene terephthalate is excellent in alkali resistance and acid resistance, and thus can be suitably used in the present invention. Next, as a laminated polymer resin film that meets the conditions of the present invention, for example, (4) PET
/ Polyvinyl alcohol / ethylene copolymer (EVAL) / Polyethylene (PE), (5) Stretched polypropylene (OPP) / EVAL / PE, (6) Unstretched polypropylene (CPP) / EVAL / PE, (7) Nylon (N ) / Aluminum foil (Al) / PE, (8) PET / Al

EVAL / LDPE, (28) ON (stretched nylon) / EVAL / LDPE, (29) SiO2 vapor-deposited PET / PE, the shape of the container used in the present invention has a hole or a notch for discharging the treatment agent at the bottom at the time of use. In order to provide it, it is preferable to have some area at the bottom of the container. In addition, at the time of disposal, a foldable container that is not bulky is preferable, and a standing pouch type can be preferably used. Further, since the bottom of the container is provided with a hole or a cut, it is preferable to make the film thickness thinner or the strength weaker than the side surface. Further, if necessary, an outlet may be provided in advance on the bottom and a cap may be attached. The outlet may be sealed with aluminum foil or the like to prevent the treatment agent from leaking and to have a structure in which holes can be easily formed. Alternatively, the cap may be perforated from above.

A concrete example of the form of the container used in the present invention is shown in FIG.
It shows in (a) -FIG.1 (e).

FIG. 1 (a) shows a rectangular flexible plastic container in which the upper part and the side are heat-sealed.

FIG. 1 (b) is a type with the outlet shown 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 provided at the bottom.

In the present invention, other containers such as a plastic bag, a milk carton and a cubic retainer can be used.

In the taking-out method of the present invention, at the time of use, the taking-out port is opened in the container filled with the treating agent.
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 surface or the upper part of the container in some cases. When the outlet is provided at the upper part, there is some trouble in sucking and taking out the liquid agent, but when supplying the cleaning water, it is not necessary to apply a water pressure and the cleaning is easy. The container can be opened by inserting the treatment agent container into a perforating blade to make a hole, by moving the blade to cut it open, or by providing the container with a discharge port beforehand. There is a method of providing an outlet by peeling off a seal such as aluminum foil.

The size of the outlet may be relatively small in the case of a liquid agent, but it is preferable to make it large in the case of a solid agent.

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

After the processing agent is discharged from the outlet, or while discharging the processing agent, a predetermined amount of cleaning water is sprayed from the cleaning water supply nozzle to clean the inside of the container.

The cleaned cleaning water is allowed to enter the processing liquid tank provided below the container.

The washing water supply nozzle is preferably integrated with the perforating blade, and a concrete structure is as shown in FIG. It is preferable that the washing water has a high water pressure in order to efficiently wash the inside of the container, and that hot water is used.

The water pressure of the washing water is set high especially 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 to 50 ° C, preferably 35 ° C
~ 45 ° C. If the cleaning 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 components of the container material may melt out. The deformation of the container and the use of high-temperature washing water poses a problem in handling safety.

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

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

As the processing agent for the silver halide photographic light-sensitive material, a black-and-white developing solution, a color developing solution, a fixing solution, a bleach-fixing solution,
A liquid agent such as a bleaching solution and a stabilizing solution for washing with water, or a solidifying agent such as a powder agent or granules thereof can be applied.

As the processing agent for the non-silver salt light-sensitive material for printing plates such as PS plate, a developing solution, a developing replenishing solution, a rinsing solution, a gum solution, or a solidifying agent such as powder or granules thereof is applied. You can

The black-and-white developing solution for 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.

EXAMPLES Examples of the present invention will be described below, but the present invention is not limited thereto. Example 1 The film composition was such that the low density polyethylene (150
μ) / Saran coat PET (12μ) / Nylon (15μ)
A container having the shape shown in FIG. 1 (a) was filled with Konica developer solution A, B, C for X-ray shown below.

Part (A) Potassium hydroxide 230 g Potassium sulfite 610 g Sodium hydrogencarbonate 120 g Diethylenetetramine pentaacetic acid 28 g 5-Methylbenzotriazole 0.5 g 1-Phenyl-5-mercaptotetrazole 0.2 g Hydroquinone 300 g Water is added and 2500 ml pH is adjusted to 11.0. Preparation Part (B) Triethylene glycol 200 g 5-Nitroindazole 1 g 1-Phenyl-3-pyrazolidone 13 g Glacial acetic acid 100 g Water added 300 ml Part (C) Glutaraldehyde bisulfite 130 g Water added 250 ml The bottom of the filled kit container was put on the perforation nozzles 1, 2 and 3 of the liquid preparation device of FIG. 3 to discharge the processing liquid therein. After that, the inside of the container was washed by ejecting an amount of washing water corresponding to about 3.3 times the total volume of the kit from the washing nozzle integrated with the perforation nozzle. The discharged wash water was used as a diluting water for the treatment liquid. The treating agent used as a working solution was sufficiently mixed by the stirrer 4, and the developer replenisher was sent to the processor by the solution sending pump 5.

At the start of development, adjust the starter,
Used at the start.

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

The fixing solution used had the following composition.

Ammonium thiosulfate 140 g Anhydrous sodium sulfite 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 Water to make a total volume of 1 liter. <Processing method> At the start of development, the developing solution was processed using an automatic processor SRX-501 (manufactured by Konica Corporation) by adding 20 ml of the starter per 1 liter of the developing solution as a starter. At this time, the amount of washing water is 2 per 1 m2 of film.
The developer replenishment rate was 250 ml / m2 at 1 / m2. The replenishment rate of the fixer was 360 ml / m2.

As the film, SR-G manufactured by Konica Corporation is used.
It was post-exposure treated.

In this way, when the X ray film was developed, it was only necessary to set the developer kit, and the development could be easily carried out for a long period of time. Since the developer container was automatically cleaned, the liquid remained in the container to some extent, but it was almost water, so that it was harmless even if it adhered to the hand. The treatment agent container was foldable and had a smaller disposal volume than that of polybin, and was excellent in disposal property. In addition, no performance fluctuation due to the residual treatment liquid in the container, which tends to be a problem with such a flexible container, was observed.

Example 2 A color development replenisher kit (10 liter kit) for color paper having the following part construction was PE (100
μ) / Nylon (2μ) / Polyurethane (3μ) / PE
A T-shaped (10 μm) film was used to fill a bag made in the shape shown in FIG. 1 (d) and the opening was heat-sealed to form a container. This was set in the liquid preparation device of FIG.

[0058] Color development replenisher for color paper Part A   Pure water about 100g   Triethanolamine 145g   N, N-diethylhydroxylamine 70g   Optical brightener 15g   Diethylene glycol 145g Pure water was added to make 0.4 liter.

[0059] Part B   Pure water about 300g   Potassium sulfite 4.3g   N-ethyl-N-β-methanesulfonamidoethyl-     65 g of 3-methyl-4-aminoaniline sulfate Pure water was added to make 0.4 liter.

[0060] Part C   Pure water about 400g   350g potassium carbonate   Potassium bromide 0.1g   Potassium chloride 3g   Ethylenediaminetetraacetic acid 15g   Catechol-3,5-disulfonic acid disodium salt 15 g   1-Hydroxyethylidene-1,1-disulfonic acid 15g Pure water was added to make 0.6 liter.

When the starting solution is used, 70% of the starting solution to be prepared is supplemented with 0.01% potassium bromide per liter of the starting solution.
Add 5g, 2.3g potassium chloride and 2.5g 50% sulfuric acid and add water to make 100%.

A Konica CL-PP1701 printer processor was charged with the starting liquid, and Konica color paper type QA-A5 was subjected to wedge exposure by a conventional method.
Running processing was performed while replenishing with the liquid feed pump 10 from the developer replenisher tank 9 shown in FIG.

The bleach-fix / stabilizer is K-20P2 manufactured by Konica.
R-01 and K-20P3R-01 were used.

The container filled with the processing liquid is pierced by the punching blades 6, 7, and 8 shown in FIG. 4, so that the container is pierced and the liquid inside falls into the developing replenisher tank. Then, the cleaning liquid is ejected from the cleaning nozzle to clean the container. Pure water heated to 40 ° C. was used as the washing water at this time. The total amount of washing water was adjusted to 8.6 l. Also,
Compressed air was simultaneously sent into the container. By doing this, the dented container bulged and the cleaning effect was improved. (Use the cleaning nozzle shown in Fig. 4 (h). You can also use a perforation nozzle with the shape shown in Fig. 4 (g).) You can set the developer replenisher without getting your hands dirty when preparing it, and take out the processing liquid from the container sufficiently. Since it can be placed in the processing liquid tank,
A stable developer replenisher could be prepared at all times, so that the quality of the processed paper was stable. Further, the developer replenisher solution container was almost water, although some solution remained therein, and there was no problem even if it adhered to the hand. Furthermore, this container can be folded at the time of disposal, and has excellent disposability.

Example 3 A positive PS plate SLP-N (manufactured by Konica Corporation) was imagewise exposed. On the other hand, 0.76 Kg of potassium silicate, 0.31 Kg of potassium hydroxide and pure water consisting of 26 wt% SiO2 and 13.5 wt% K2O.
A positive PS plate development replenisher of 0.31 Kg was granulated with a stirring granulator. 0.6 kg of developer was obtained.

This granule developer was filled in the standing pouch type container (A) of FIG. 1 (d) having the following layer structure and heat-sealed.

Container (A) Polyethylene 75μ / Eval 12μ / Alμ / PET 15μ Separately, rinse solution SRW-1 (manufactured by Konica Corp.) was powdered with a spray dryer and the standing pouch type container (B) shown in FIG. 1 (d). ) And sealed.

Container (B) From the inside Polyethylene / Nylon 6.10 / Al / Polyethylene Total film thickness 250 μm.

When the above-mentioned powdery PS plate treating agent was used, the upper part was cut with scissors as shown in FIG. 5 (k) and put into each treating solution tank by hand. However, at this time, the powder agent still remains on the wall of the container. This container is placed upside down and covered with the cleaning nozzle of the device of FIG. 5 (i), and a pump for supplying cleaning water is operated to supply a certain amount of cleaning water into the container.
The container was washed. This wash water drops down, enters the treatment liquid tank, and is used as dilution water. For the cleaning water of the development replenisher, use a magnet pump that delivers 10 liters per minute,
4 l of cleaning water was supplied from a cleaning water supply nozzle having 5 nozzle holes each having a hole diameter of 1 mm to clean the inside of the container. This 4 liters of washing water enters the developing replenisher tank below, and diluting water (dissolved water)
Becomes The cleaning water used at this time was heated by a heater provided in the cleaning tank and the temperature was adjusted to 35 ° C.

No residual granule developer or powdered gum in the container was visually observed. The pH of the prepared developer replenisher was pH 13.80 at 25 ° C., which was a standard pH value. When a running process was carried out for a long time while replenishing the automatic developing machine with this replenishing solution, the finish of the PS plate was stable.

The rinse liquid was also replenished normally, 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 introduced.
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 the same as in Example 3. As a result, a considerable amount of solid treatment agent still remained in the treatment agent container. (FIG. 5 (l)) In particular, the side portion of the container had a small clearance, and the force to flatten the container worked, and the powder treatment agent was likely to remain. When the container was shaken in an attempt to take out sufficient powder from the container, the powder was scattered and soiled the equipment and floor. However, the solid material still remained in the container.

The prepared developer replenisher had a pH of 13.65 at 25 ° C., which was lower than the standard, because the powder processing agent was less than the predetermined amount, and when it was replenished to the automatic processor, a long-term running process was performed. As a result, the developability of the PS plate deteriorated, the halftone dots in the shadow portion of the printed matter were easily crushed, and the reproducibility of the shadow portion deteriorated.

On the other hand, the replenishment of the rinse solution is also likely to be insufficient, and the erasing portion of the plate is contaminated during printing.

Comparative Example 2 In Example 2, the color development replenisher kit for color paper is filled in the container shown in FIG.
The upper corner of the container was cut with scissors without using the apparatus of No. 1 and the processing solution was manually injected into the developer replenisher tank.

Then, an experiment was conducted in the same manner as in Example 2 except that predetermined diluting water was added to the developer replenisher tank, stirred, and used as the developer replenisher.

As a result, a liquid residue was found in the processing agent container, and the amount thereof was larger than that in the case where the polybin container was used, and the used liquid component of the developing replenisher became thinner than the predetermined amount, and the developing property tended to deteriorate.

When the standing pouch-type treatment agent container was opened, liquid dripping could not be prevented, and there was a problem that the liquid remaining in the treatment agent container adhered to hands and clothes, and the floor was soiled. In addition, the scissors used when opening the processing agent container are rusty, which is an unfavorable result in terms of work.

[0079]

According to the method of taking out the treating agent of the present invention, the treating agent can be easily taken out 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. And has excellent processing performance.
