Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a processing agent part for silver halide photographic light-sensitive materials, and more specifically, it has improved storage stability of the processing agent and can process used containers without adversely affecting the environment. The present invention relates to a processing agent part for silver halide photographic light-sensitive materials.

[0002]

2. Description of the Related Art Processing agents for silver halide photographic light-sensitive materials (hereinafter also referred to as "processing agents for photographic materials") are generally supplied as concentrates or powders, and diluted or dissolved in a certain amount of water before use. By doing so, a working solution is prepared. These concentrated solutions or solid processing agents are oxidized by oxygen in the air. If it is a concentrated developer or solid developer,
The concentration of the developing agent or preservative decreases, and the developability after storage with time deteriorates. Further, in the case of a fixing concentrate or a solid fixing agent, thiosulfuric acid which is a fixing agent is oxidized to generate sulfur.

Therefore, there has been a demand for a concentrated solution of a treating agent or a solid treating agent for which the performance is not deteriorated even after long-term storage. Conventionally, various contrivances have been made to these air oxidations, such as increasing the amount of preservative, improving the sealing property of the container, and sealing the inside of the container with an inert gas.
Since the activity of the processing agent is being increased in response to the demand for faster development processing, further improvement in long-term storage stability has been demanded.

On the other hand, in recent years, environmental problems have become more serious, and environmental suitability of waste materials is required. Conventionally, a container made of polyethylene is used as a treatment agent, and a used container is reused by incineration treatment or landfill disposal or recovery.

However, in recent years, environmental problems have become serious, and various restrictions have been imposed on disposal methods and reuse.
For example, when plastics are extinguished, they generate a large amount of heat and the capacity of the furnace must be strengthened. In addition, regarding landfill, the amount of waste in the urban area has increased remarkably and there is no landfill.
Problems such as landfill and illegal dumping to other prefectures are also occurring.

Further, the solid processing agent contains components that generate gas by self-decomposition and reaction with other components. In particular, these components react with other components having a lower pH (for example, chelating agent, main agent, pH adjusting agent, photographic performance adjusting agent, etc.) by using water that has permeated the container from the outside and entered into the inside as a medium. As a result, gas is likely to be generated, and the generated gas causes bulging or rupture of the container, which becomes a problem.

[0007]

SUMMARY OF THE INVENTION Therefore, the object of the present invention is to improve the long-term storability of a processing agent, and further, to process a used container capable of processing a used container without adversely affecting the environment. To provide a drug part. or,
Another object is to provide a solid processing agent kit part for silver halide photographic light-sensitive material, which suppresses gas generation due to long-term storage and prevents expansion and rupture of the container.

4-85534 and 4-172341).

A preferred method for producing a tablet is a method in which a solid processing agent in powder form is granulated and then a tableting step is performed to form the tablet. Compared to a solid processing agent formed by a tableting process by simply mixing a solid processing agent component, there is an advantage that solubility and storage stability are improved, and as a result, photographic performance is also stabilized.

The granulation method for tablet formation includes rolling granulation,
Known methods such as extrusion granulation, compression granulation, crushing granulation, stirring granulation, fluidized bed granulation, and spray drying granulation can be used. For tablet formation, the average particle size of the obtained granulated product, when the granulated product is mixed and compressed under pressure, the components become non-uniform,
100-800 in that so-called segregation hardly occurs.
μm, more preferably 2 μm.
It is 00 to 750 μm. Further, the particle size distribution is preferably such that 60% or more of the granulated product particles have a deviation of ± 100 to 150 μm.

Next, when the obtained granulated product is compressed under pressure, a known compressor such as a hydraulic press, a single-shot tableting machine, a rotary tableting machine, or a pre-ketching machine is used. You can The solid treatment agent obtained by compression under pressure can have any shape, but from the viewpoint of productivity and handleability, or from the problem of dust when used on the user side, it is a cylindrical type. So-called tablets are preferred.

More preferably, at the time of granulation, the above-mentioned effects become more remarkable by separately granulating each component, for example, an alkali agent, a reducing agent, a preservative and the like.

A method for producing a tablet processing agent is described in, for example, Japanese Patent Application Laid-Open No.
Nos. 1-61837, 54-155038 and 52-
No. 88025, British Patent No. 1,213,808, etc., and can be produced by a general method. Further, granulating agents are described in, for example, JP-A Nos. 2-109042 and 2-109043.
And JP-A-3-39735, JP-A-3-39939, and the like. Further, powder processing agents are disclosed in, for example, JP-A-54-133332, British Patent
It can be produced by a general method as described in JP-A Nos. 25,892 and 729,862 and German Patent 3,733,861.

The bulk density of the solid processing agent is 1.0 in the case of tablets in view of its solubility and the effect of the object of the present invention.
2.5 g / cm ³ is preferable, and when it is larger than 1.0 g / cm ³ , the strength of the obtained solid is 2.5 g / cm ^3.
A smaller size is more preferable in terms of solubility of the obtained solid. When the solid processing agent is granules or powder, the bulk density is preferably 0.40 to 0.95 g / cm ³ .

The solid processing agent used in the present invention is used as a photographic processing agent such as a developer, a fixing agent and a rinse agent.
It is the developer that has a great effect of the present invention, particularly the effect of stabilizing the photographic performance.

It is within the scope of the present invention to solidify a part of the components of a solid treating agent, but it is preferable that all the components of the treating agent are solidified. It is desirable that each component is molded as a separate solid processing agent and is packaged in the same package. It is also desirable that the separate components are packaged in the order in which they are periodically charged repeatedly.

It is preferable to add all of the processing agents to be replenished to the respective processing tanks as solid processing agents according to the processing amount information. When replenishing water is required, replenishing water is replenished based on the processing amount information or other replenishing water control information. In this case, the liquid to be replenished to the processing tank can be only replenishing water.
That is, when two or more processing tanks need replenishment, only one tank is required to store the replenishing liquid by sharing the replenishing water, and the size of the automatic developing machine can be reduced. The replenishing water tank may be provided externally or may be built in an automatic developing machine, and the built-in water tank is preferable in terms of space saving and the like.

When the developer is solidified, all of the alkaline agent and the reducing agent are solidified, and in the case of a tablet, at least 3 agents or less, most preferably 1 agent is used in the present invention. It is a preferred embodiment of the solid treatment agent. In addition, when it is divided into two or more agents and made into a solid treatment agent,
It is preferable that the plurality of tablets and granules are packed in the same package.

As the supply means for supplying the solid processing agent to the processing tank, for example, when the solid processing agent is a tablet, there are No. 63-13783, 63-97522, and No. 1-85732. Although there is a known method, 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 granules or powder, it is used in JP-A-62-81964 and 63-84.
No. 151, JP-A-1-292375 and the like, and a gravity drop method described in JP-A-63-105159 and JP-A-63-195.
Although there is a known method using a screw or a screw described in No. 345 or the like, the method is not limited thereto.

However, the 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 in accordance with the processing amount of the photosensitive material is packaged. A method of opening and taking out is conceivable. Specifically, the solid processing agent is sandwiched and housed in a package constituted by at least two packaging materials in a predetermined amount, preferably in a replenishment amount for one time, and the package is separated in two directions or the package is separated. A part of is opened so that it can be taken out. The solid processing agent in a retrievable state can be easily supplied to the processing tank having the filtering means by spontaneous dropping. A certain amount of solid treatment agent is stored in a package that is divided and sealed so that the air permeability to the outside air and the adjacent solid treatment agent is blocked, so moisture resistance is guaranteed unless it is opened. ing.

In an embodiment, a package made of at least two packaging materials sandwiching the solid processing agent is adhered or adhered to each other so that the periphery of the solid processing agent can be separated. Can be considered. By pulling the packaging materials sandwiching the solid treatment agent in different directions, the closely contacted or adhered contact surfaces are separated and the solid treatment 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 sandwiching the solid processing agent can be opened by an external force. The term "opening" as used herein means a notch or a 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 unopened side through the solid processing agent in the direction of the unsealing packaging body, or the packaging on the openable side. It is conceivable that the solid treatment agent can be taken out by making a cut with a sharp member on the body.

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

The solid processing agent supply means has a control means for feeding a fixed amount of the solid processing agent according to information on the processing amount of the photosensitive material, which is an important requirement. That is, in an automatic processor, the component concentration in each processing tank is kept constant,
Necessary for stabilizing photographic performance. The processing amount information of the photographic material is a value proportional to the processing amount of the photographic material processed with the processing solution, the processing amount of the processed photographic material, or the processing amount of the photographic material being processed. The amount of reduction of the treating agent in the liquid is indicated indirectly or directly. The detection may be performed at any timing before or after the photosensitive material is carried into the processing solution, or during immersion in the processing solution. Furthermore,
It may be a physical parameter such as the concentration of the composition in the processing solution or a change in the concentration, pH or specific gravity. Alternatively, the amount of the treatment liquid that has come out after drying may be used.

The solid processing agent may be charged in a processing tank, but preferably, it is communicated with a processing section for processing the light-sensitive material, and the processing liquid is flown between the processing section and the processing section. It is preferable that it is a place, there is a certain amount of circulating treatment liquid between the treatment unit and the treatment unit, and dissolved components move to the treatment unit.
The solid processing agent is preferably added to the temperature-controlled processing liquid.

Generally, since the temperature of an automatic processor is adjusted, the temperature of the processing liquid is adjusted by an electric heater. As a general method, a heat exchange unit is provided in the auxiliary tank connected to the processing layer, a heater is installed, and a pump is arranged in this replenishment tank so that the liquid is sent from the processing tank at a constant circulation rate and the temperature is kept constant. Have been.

A filter is usually arranged for the purpose of removing the crystalline foreign matter that is mixed in the processing liquid or is generated by crystallization, and plays a role of removing the foreign matter.

The most preferable method is to add the solid processing agent to a location where the temperature is adjusted, such as a location communicating with the processing section such as this auxiliary tank. This is because the insoluble component in the processing agent that has been added is blocked from the processing section by the filter section, and it is possible to prevent solids from flowing into the processing section and adhering to photosensitive materials, etc. Will also be very good.

Further, when the processing agent input section is provided in the processing tank together with the processing section, it is preferable to devise a shield or the like so that the insoluble portion does not come into direct contact with the film or the like.

As the material of the filter and the filtering device, all those used in general automatic developing machines can be used, and the special structure and material do not influence the effect of the present invention.

The number of times of circulation of the treatment liquid circulated by the circulation means is preferably 0.5 to 2.0 times / min, and particularly preferably 0.
8 to 2.0 times / min, further 1.0 to 2.0 times / min
Is preferred. As a result, the dissolution of the solid processing agent is promoted, the occurrence of agglomeration of the high-concentration liquid can be prevented, the unevenness of the density of the processed photosensitive material can be prevented, and the insufficiently processed photosensitive material can be generated. Can be prevented. Here, the number of circulations indicates the flow rate of the circulated liquid, and the time when the liquid amount corresponding to the total liquid amount in the processing tank flows is defined as one time.

The solid treating agent according to the present invention is added to the treatment tank separately from the replenishing water, and the replenishing water is supplied from the replenishing water tank.
