Description

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 / or a processing method of a silver halide photographic light-sensitive material, which comprises dissolving and replenishing with a peripheral device.

[0002]

2. Description of the Related Art So-called 3K which is tight, dirty, and dark
The work style represented by (1) has become more and more repelled by workers in recent years, and along with this, there is a growing demand in the medical industry for improvements in the processing area of automatic processors. That is, it is possible to reduce the load of replenishment work for development and fixing.

Each industry has been making efforts to maintain the global environment, but in the photographic industry as well, from the viewpoint of the processing load of the photographic waste liquid, the amount of the waste liquid is reduced and further replenished. Reuse of plastic containers used for liquids is cited as a future issue.

On the other hand, however, since it is a device and material used for medical diagnosis, the system performance including the silver halide photographic light-sensitive material (hereinafter also simply referred to as light-sensitive material), the processing agent and the device is At present, in terms of performance stability and reliability, it is required to have a level higher than that of other general-purpose equipment and materials because it has a great impact on human life.

Considering the reduction in the use of plastic bottles, the use of powder treating agents is considered. That is, the current method of diluting a concentrated solution with a chemical mixer is transported and sold in a state where the concentrated solution is packaged in a poly pot, but by making it into a powder, it becomes a poly bag with a small amount of PET used. It can be packaged, and since there is no water, the powder treatment agent is lighter and easier to carry.

However, it takes time and effort to dissolve the powder processing agent, and the work load of the worker is rather increased. Furthermore, when dissolved, the powder flew away, and there was a big problem in terms of safety.

In order to improve the above problems, a method of forming a powdery processing agent into a tablet shape or a method of forming into a so-called granular shape can be considered, but in the medical industry, the processing amount of a photosensitive material per unit time is processed. Is relatively large, and the solubility of the solid processing agent is inferior, causing a large problem in causing performance fluctuations.

That is, the performance fluctuation means the following.

As the throughput of the light-sensitive material per unit time increases, the stability of performance deteriorates. Specifically, a decrease in sensitivity and a decrease in γ occur. Further, when the developer contained in the developing tank of the automatic developing machine becomes 7 L or less, the stability of the performance is impaired. Specifically, the sensitivity and γ vary during processing. When the amount of silver coated on the light-sensitive material exceeds 3 g / m ² , the silver tone deteriorates. When the I content of the light-sensitive material is 0.5 mol% or more, the sensitivity and γ during processing are varied and stable performance cannot be obtained. When the concentration of the developing agent in the developing solution is 0.9 mol / L or less, the sensitivity and γ change during processing.

[0010]

SUMMARY OF THE INVENTION In view of the above problems, an object of the present invention is to reduce the sensitivity and γ, the sensitivity and γ do not change during processing, and the silver halide photography with little deterioration in silver tone.

The four-way seal, the three-way seal, and the stick (pillow, gusset) packaging have different forms, and the above materials are used. However, when using the peel open method, a sealant agent is laminated to give the peel open aptitude.

The peel-open method generally includes a cohesive failure method, an interfacial peeling method, and an interlayer peeling method.

The cohesive failure method is an adhesive called hot melt, which is used as a sealant in a heat seal lacquer, and peels off due to internal cohesive failure of the sealant layer at the time of opening.

The surface-active peeling method is a method of peeling at the interface between films, in which the sealing film (sealant) and the adherend are not completely fused and can be peeled with an appropriate strength. The sealant is a film in which an adhesive resin is mixed, and polyethylene, polypropylene or a copolymer thereof, polyester, or the like can be selected depending on the material of the adherend.

PTP is a type of blister pack that is molded into P
It is a packaging form in which a solid processing agent is put into a sheet such as VC or CPP and heat-sealed with an aluminum sealing material.

Environmentally, PVC is not used as a forming material, and recently A-PET and highly moisture-proof PP (for example, TAS-1130, TA
S-2230, TAS-3230: Taisei Kako Co., Ltd. are preferably used.

The preferred polyvinyl alcohol is a very good film-forming material and has good strength and flexibility under most conditions. Commercially available polyvinyl alcohol compositions cast as films vary in molecular weight and degree of hydrolysis, but have molecular weights of about 10,000 to about 10,0.
It is preferably 000. The degree of hydrolysis is the rate at which the acetic acid ester group of polyvinyl alcohol is replaced with a hydroxyl group.

In the present invention, as the supply means for supplying the solid processing agent to the processing tank, for example, when the solid processing agent is a tablet, Japanese Utility Model Publication Nos. 63-137783 and 63-97522,
Although there is a known method such as Japanese Utility Model Laid-Open No. 1-85732, any method may be used as long as it has at least the function of supplying tablets to the processing tank. Further, when the solid processing agent is a granule or powder, it is used in Japanese Utility Model Laid-Open Nos. 62-81964, 63-84151 and JP-A-1-
No. 292375, the gravity drop method described and No. 63-105159,
The method using screws or screws described in JP-A-63-195345 and the like is a known method, but is not limited thereto.

However, a preferable method is, as a supply means for supplying the solid processing agent to the processing tank, for example, a predetermined amount of the solid processing agent which is previously weighed and divided and packaged is opened according to the processing amount of the light-sensitive material, and the package is opened. A method of taking it out is possible. Specifically, the solid processing agent is sandwiched and housed in a package composed of at least two packaging materials by a predetermined amount, preferably one replenishment amount, and the package is separated in two directions or the package A part of it is opened so that it can be taken out. The solid processing agent that can be taken out can be easily supplied to the processing tank having the filtering means by spontaneous fall. A predetermined amount of the solid processing agent is housed in a package that is divided and hermetically sealed so that the air permeability between the solid processing agent and the adjacent solid processing agent is blocked. Therefore, moisture resistance is guaranteed unless the package is opened.

As an embodiment, it is conceivable that a package composed of at least two packaging materials sandwiching the solid processing agent is closely adhered or adhered to each other so that the periphery of the solid processing agent can be separated. . By pulling the respective packaging materials sandwiching the solid processing agent in different directions, the closely contacted or adhered contact surfaces are separated, and the solid processing agent can be taken out.

As another embodiment, it is conceivable that at least one of the packages made of at least two packaging materials can be opened by an external force so as to sandwich the solid processing agent. The term "opening" as used herein means a cut or break that leaves a part of the packaging material. As the unsealing method, the solid processing agent is forcibly pushed out by applying a compressive force from the packaging body on the non-opening side to the packaging body which can be opened through the solid processing agent, or on the packaging body on the openable side. It is considered that the solid processing agent can be taken out by making a cut with a sharp member.

The supply start signal is obtained by detecting the processing amount information. The supply stop signal is obtained by detecting the information that the supply of the predetermined amount is completed. Further, when the treatment agent is packaged and needs to be opened, the driving means for separating or opening based on the obtained supply start signal operates, and the driving means for separating or opening based on the supply stop signal is It can be controlled to stop.

The above-mentioned solid processing agent supplying means has a control means for charging a fixed amount of the solid processing agent in accordance with information on the processing amount of the light-sensitive material, which is an important requirement in the present invention.
That is, in the automatic developing machine of the present invention, it is necessary to keep the component concentration in each processing tank constant and to stabilize photographic performance. What is the processing amount information of silver halide photographic light-sensitive materials?
It is a value proportional to the processing amount of the silver halide photographic light-sensitive material processed with the processing solution, the processing amount of the processed silver halide photographic light-sensitive material, or the processing amount of the silver halide photographic light-sensitive material being processed. It indicates indirectly or directly the amount of reduction of the treating agent in the liquid. It may be detected before or after the photosensitive material is carried into the processing liquid, or at any timing during immersion in the processing liquid. Further, it may be a physical parameter such as the concentration of the composition in the treatment liquid or a change in the concentration, pH and specific gravity. Further, it may be the amount of the treatment liquid which is discharged to the outside after drying.

It is preferable that the structure is such that the dissolved components move to the processing section because there is a certain amount of processing liquid circulation between the processing section and the processing section. The solid processing agent is preferably added to the temperature-controlled processing liquid.

Generally, the temperature of an automatic processor is adjusted, so that the temperature of the processing liquid is adjusted by an electric heater.
