Description

Description: FIELD OF THE INVENTION The present invention relates to a method for processing a silver halide photographic light-sensitive material, and in particular, to reverse a washing water and / or a stabilizing solution taken out in a washing and / or stabilizing process. The present invention relates to a method for processing a silver halide photographic material which is regenerated by osmosis membrane processing.

[Conventional technology]

The silver halide color photographic light-sensitive material is subjected to processing such as color development, bleach-fixing, and water washing after receiving imagewise exposure.

The silver halide reversal color photographic light-sensitive material is subjected to processing such as black development before color development. The silver halide black-and-white photographic light-sensitive material is subjected to processing such as black-and-white development, fixing, and washing with water after imagewise exposure.

In recent years, from the viewpoints of environmental conservation and resource saving, reduction of harmful components in wastewater, reduction or no discharge of wastewater, and reduction of washing water have been required, and various studies have been conducted to meet these requirements. Have been.

Regarding the reuse of washing water, use the ion conversion resin method (J. Ap
pl.Phot.Eng., 6, 120 (1980 ), the 5, 141 (1979)) and reverse osmosis unit (see USSR Patent No. 701963) are known.

Among them, technology for reverse osmosis treatment of washing water has been improved, and one of the color photographic processing devices is provided with a reverse osmotic pressure device, and a liquid inlet and a concentration side outlet of the reverse osmotic pressure device. And the dilution side outlets are connected to the washing tank, the bleach-fixing tank and the washing tank, respectively, and the concentrated liquid produced by treating the washing wastewater from the washing tank with the reverse osmotic pressure device is diluted into the bleach-fixing tank. The liquids are respectively returned to the washing tanks (JP-A-58-105150).

Further, after the silver halide color photographic light-sensitive material is color-developed, processed with a processing solution having a fixing ability, and then stabilized with a stabilizing solution without substantially washing with water, the stabilizing solution is subjected to reverse osmosis. A treatment method for film treatment has been proposed (JP-A-60-241053). According to this treatment method, generation of yellow stain during long-term storage and stain immediately after the treatment is prevented.

Furthermore, after processing the silver halide color photographic light-sensitive material in a bath having a fixing ability so as to reduce the concentrated solution discharged from the reverse osmosis membrane processing apparatus and reduce the replenishment of the washing water,
When washing and / or stabilizing by the multi-stage countercurrent method, the overflow liquid from the washing tank and / or the stabilizing tank is introduced into the storage tank, and the liquid in the storage tank is subjected to reverse osmosis membrane treatment and reverse osmosis membrane treatment. A method for processing a silver halide color photographic light-sensitive material has been proposed in which the permeate is treated in a washing tank and / or stabilizing tank and the concentrated solution is returned to a storage tank while returning the concentrated liquid to the storage tank in JP-A-62-25.
No. 4151). According to this method, the amount of water in the washing and / or stabilization treatment step can be significantly reduced, and treatment can be performed without increasing yellow stain despite saving water.

The reverse osmosis membrane treatment method of the washing water and the stabilizing solution is a very useful method for greatly reducing the amount of water in the washing and stabilizing treatment steps.

[Problems to be solved by the invention]

The problem in saving the washing water or stabilizing solution is that aminopolycarboxylic acid secondary
The concentration of the aminopolycarboxylic acid ferric complex salt, for example, EDTA-Fe in the water or the liquid in the washing tank or the stabilizing tank is increased by bringing in from the bath having the fixing ability containing the iron complex, especially in the final bath. Is to increase the concentration. In particular, when the concentration of the final bath exceeds 0.0003 mol /, an increase in yellow stain of the processed photographic material becomes a problem. Also,
Since the silver concentration in the final bath increases, silver stains on the photosensitive material due to generation of silver sulfide and the like also occur.

Since any of the above-described treatment methods is intended to regenerate the washing wastewater or the stabilized wastewater by reverse osmosis membrane treatment and obtain uncontaminated washing water or a stabilized liquid,
In the reverse osmosis membrane treatment, a reverse osmosis membrane which is highly treated so as to obtain high-purity washing water or a stabilizing solution has been used. In particular, in the processing apparatus of Japanese Patent Application Laid-Open No. 58-105150, valuable components in the washing water are collected and returned to the bleach-fixing tank, so that a reverse osmosis membrane that hardly allows solutes to pass through is used. I have. Such reverse osmosis membranes have micropores, which increase the operating pressure. In fact, the operating pressure in the processing apparatus of the JP 58-105150 is 40~50kg / cm ^2, also stabilizing solution in the reverse osmosis membrane treatment to that JP 60-241053 Patent processing methods The operating pressure is 55 kg / cm ² .

The present inventor has studied a processing method of a silver halide color photographic light-sensitive material combined with a reverse osmosis film processing. As a result, when EDTA-Fe is completely removed by the reverse osmosis film processing, generation of yellow stain is extremely reduced. I understand.

This is because the generation of yellow stain can be suppressed by the processing method of JP-A-60-241053 because a reverse osmosis membrane having a high operating pressure is used as described above, solute, that is, EDTA-Fe Can be described as having been completely removed. It seems that yellow stain is suppressed in the processing method of JP-A-62-254151. These treatment methods use a reverse osmosis membrane having micropores so that almost all solutes are removed as described above.

When a reverse osmosis membrane having such micropores is used, the washing water or the stabilizing solution seems to be highly regenerated, however, it is highly regenerated in this way to remove all salts and the like. If the silver halide color photographic light-sensitive material is washed with water or a liquid, there arises a problem that reticulation occurs due to a change in humidity during storage after processing. This is because fine crepe-like wrinkles are generated on the emulsion film surface and gloss is turbid. As a result, the quality of the image quality is significantly impaired. Further, at this time, the discoloration of the cyan dye increases as a negative effect.

After examining the cause and countermeasures, the extremely low salt content in the washing water caused the emulsion layer to easily swell with respect to humidity. To increase the stability, NH ₄ ions, K ions, N
It turns out that it is better to have a little ion left. This NH ₄
The ions, K ions, and Na ions are those brought in by ammonium thiosulfate in a bath for bleaching or bleach-fixing.

In the present invention, in the reverse osmosis membrane treatment, while EDTA-Fe causing yellow stain is completely removed,
It is an object of the present invention to provide a method for processing a silver halide color photographic light-sensitive material which allows a small amount of NH ₄ salt to remain in the permeated water and can maintain a sufficiently large amount of permeated water.

[Means for solving the problem]

The present inventor has studied various conditions of reverse osmosis membrane treatment using various reverse osmosis membranes. As a result, the NaCl rejection rate when sending a NaCl 1000 ppm solution at 25 ° C. and a pressure of 7 kg / cm ² was 30 to 90%. It has been found that when the reverse osmosis membrane treatment is performed using the reverse osmosis membrane, the above object is achieved, and the present invention has been achieved.

That is, the present invention relates to a method for processing a silver halide photographic light-sensitive material, comprising the steps of processing a silver halide photographic light-sensitive material in a bath having a fixing ability, and then processing in a washing bath and / or a stabilizing bath. And / or take out the washing water and / or the stabilizing solution from the stabilizing bath, and wash the taken out washing water and / or the stabilizing solution with a 1000 ppm NaCl solution at 25 ° C. under a pressure of 7 ° C.
NaCl rejection rate when a sending kg / cm ² is reproduced in the reverse osmosis membrane treatment using 30 to 90% of the reverse osmosis membrane, the water washing bath washing water and / or stabilizing solution is reproduced and And / or returning to a stabilizing bath.

This processing method is particularly effective for processing a silver halide color photographic light-sensitive material having a color development step and a bleaching step.

Conventionally, reverse osmosis membranes having micropores of various sizes exist, and it has been considered that they have transmission characteristics based on the micropores. However, it is difficult to accurately measure the microstructure such as the porosity of the membrane, and there is a drawback that even when measuring what can pass through, it is not possible to make a comparison using different substances. Recently, the characteristics of reverse osmosis membrane
The expression by the magnitude of NaCl exclusion when permeating a Cl solution has come to be used as standard.

There is a considerable correlation between the NaCl rejection and the state of the micropores in the membrane.

The present invention has a NaCl rejection rate of 30
~ 90% reverse osmosis membranes are used, among which 40 ~
Preferably it is 85%, particularly preferably 50-80%. Among them, the removal rate (rejection rate) of EDTA-Fe (III)
However, those having a performance of 90% or more are preferable.

Specific examples of such a reverse osmosis membrane include, for example, DRA-40, DRA-80, and DRA-89 manufactured by Daicel Chemical Industries, Ltd., with DRA-80 being particularly preferred. These are made of a polysulfone porous membrane as a support, and an aromatic polyamide having an anionic charge thereon as a separation membrane having a thickness of about 0.2 μm.
m. Such a membrane in which the separation membrane and the support are adhered to each other is called a composite membrane. DRA-40 has a rejection of about 45% when a 1000 ppm NaCl solution is pumped at 7 kg / cm ² ,
-80 is about 80% and DRA-89 is about 85%. This membrane is resistant to bacteria because it is a synthetic polymer, whereas the conventionally used cellulose acetate membrane was susceptible to bacteria, which has great significance for use in photographic wastewater. . Further, SU-200 manufactured by Toray Industries, Inc. can also be used. Both SU-200 and DRA are synthetic composite membranes of a similar aromatic polyamide separation membrane and a polysulfone support. SU−
The NaCl rejection of 200 is about 60%.

These reverse osmosis membranes use a cellulose acetate membrane, an ethyl cellulose / polyacrylic acid membrane, a polyacrylonitrile membrane, a polyvinylene carbonate membrane, a polyether-based composite membrane, a cross-linked aramid-based composite membrane, a cross-linked polyamide composite membrane, or the like. be able to.

As the structure of the reverse osmosis membrane, any of a spiral type, a tubular type, a hollow fiber type, a pleated type, and a rod type can be used. The film may be a single-layer film or a composite film, but a composite film made of a synthetic resin (synthetic composite film) is preferable from the viewpoint of durability against EDTA-Fe.

These reverse osmosis membranes include a skin layer that controls the membrane performance such as the amount of permeated water and an exclusion rate, and a support layer that supports the skin layer. Both of them are asymmetric membranes made of the same material and composite membranes made of different materials. An example of an asymmetric membrane is a cellulose acetate membrane, and a composite membrane is a polysulfone support layer coated with polyethyleneimine and tolylene diisocyanate to form a skin layer, or furfuryl alcohol is polymerized to form a skin layer. There are synthetic composite membranes using synthetic materials such as those formed. For details, see Separate volume Chemical Industry 297 “Development and practical application of advanced separation technology” published by Chemical Industry Co., Ltd., pages 155 to 172.
As described on the page, in the present invention, these synthetic composite membranes are preferably used in view of the rejection rate, the amount of permeated water, and the durability to EDTA-Fe. Synthetic composite membrane refers to a membrane formed by adhering a synthetic polymer thin film having a solute separating action onto a synthetic polymer porous support.

In the present invention, a preferred synthetic composite membrane is a polysulfone porous membrane reinforced with a polyester nonwoven fabric as a support, and a polymer thin film formed by plasma polymerization or interfacial polymerization on this support is preferable.
It is preferable that a crosslinking reaction is performed at the same time. As the thin film material, an aromatic polyamide or an aromatic polyimide is preferably used, and the thickness of the thin film is preferably 0.1 μm to 0.4 μm, particularly preferably 0.15 μm to 0.25 μm.

The reverse osmosis membrane used in the conventional reverse osmosis membrane treatment has a NaCl rejection of 95% or more. This is because, as described above, the solute is to be removed as completely as possible. 95 NaCl rejection
% Requires a high operating pressure to obtain a practical amount of permeated water. The NaCl rejection of the present invention is 30 to 90.
%, A sufficiently large amount of permeated water can be obtained at ² to 10 kg / cm ² . Specifically, in the case of the above-mentioned reverse osmosis membranes DRA-40 and DRA-80 in which the NaCl rejection is 45% and 80%, 5 to 10 kg / cm ₂
, A sufficient amount of permeated water can be obtained, whereas a reverse osmosis membrane DRA-98 having a 98% NaCl rejection rate cannot achieve the same amount of permeated water unless the water is 15 kg / cm ² or more. In the present invention, preferably 3 to 7 kg / cm ² , more preferably 3 to 5 kg / cm ²
It is desirable to feed the liquid in m ^{2 from the} viewpoint of cost, power consumption, noise, and reduction of heat generation.

The above reverse osmosis membrane treatment is particularly effective when the washing bath or the stabilizing bath is performed in a multi-stage countercurrent system in order to save the washing water or the stabilizing solution.

The position where the washing water or the stabilizing solution is taken out from the washing step or the stabilizing step for the reverse osmosis membrane treatment is taken out from the third step when the washing tank or the stabilizing tank is provided, for example, in four stages. It is preferable that the permeated water subjected to the reverse osmosis membrane treatment and regenerated is supplied from the fourth stage to which new water or liquid is supplied. The rinsing water or stabilizing liquid may be removed from each of the rinsing or stabilizing tanks, or from two or more of them. In the present invention, the washing or stabilizing bath is preferably multi-stage, preferably 3 to 5 stages, more preferably 3 to 4 stages. When there are multiple stages, a countercurrent replenishment system is preferred.

In the present invention, by performing the reverse osmosis membrane treatment, EDTA / Fe in the final bath in the washing bath or the stabilizing bath is used.
(III) concentration may cause yellow stain
It can be suppressed below 0.0003 mol /. The concentration of EDTA • Fe (III) in this final bath varies depending on the concentration of the bleach-fixing solution, the amount of permeated water in the reverse osmosis membrane treatment, and the amount of washing water or replenishment of the stabilizing solution. Is desirably 0.0002 mol / or less, and particularly preferably 0.0001 mol / or less.

On the other hand, in the reverse osmosis membrane treatment, a small amount of NH ₄ salt can be left in the permeated water, which is effective in preventing the occurrence of reticulation of the photosensitive material. In order to achieve the above effect sufficiently, the NH ₄ salt concentration in the permeated water is 6.7 × 10 ^{−4 to} 3.
It is preferably in the range of 4 × 10 ⁻⁴ mol /. In this case, the amount of ammonium salt or the like added for stabilizing an image to be added to the stabilizing solution described later can be reduced. It is effective. NH of permeate
_{(4) The} salt concentration is determined mainly by the type of the washing water and / or the stabilizing solution (NH ₄ salt concentration) guided to the reverse osmosis membrane treatment and the type of the reverse osmosis membrane. By choosing from which stage of the bath to take out the washing bath and / or the stabilizing liquid, the permeate NH
_{(4) The} salt concentration can be set so as to be in the above range. For example, as described above, when the washing tank or the stabilization tank is provided in four stages, take out from the third stage,
When the NH ₄ salt concentration of the permeated water does not reach the above range when the reverse osmosis membrane treatment is performed, the NH ₄ salt concentration may be higher in the former stage, and may be taken out from the second stage.
You may take out from a stage and a 3rd stage, respectively.

In the present invention, various compounds may be added to the washing water or the stabilizing solution. For example, a hardener represented by a magnesium salt or an aluminum salt, or a surfactant for preventing a drying load or unevenness, a fluorescent whitening agent for improving whiteness, a sulfite as a preservative, and the like. is there.

Preferably it is 10 to 35 degreeC. If necessary, a heater, a temperature controller, a circulation pump, a filter, a floating pig, a squeegee, and the like may be provided in the washing tank or the stabilizing tank.

In the treatment method of the present invention, the replenishing amount of the washing water or the stabilizing solution is
Since the replenishing rate is less than 200 ml / m ^2, it is effective when applied when the concentration of the aminopolycarboxylic acid ferric complex in the final bath of the washing tank or the stabilizing tank is increased. In particular, in the washing tank when the stabilizing tank of the three stages in the case of 50~190ml / m ^2, 4-stage is effective when 50~120ml / m ^2.

[Action]

In the present invention, in a method for processing a silver halide color photographic light-sensitive material, a NaCl 1000 ppm solution is subjected to a reverse osmosis membrane treatment at 25 ° C.
When a reverse osmosis membrane with a NaCl rejection rate of 30 to 90% when sent at a pressure of 7 kg is used, 95% or more of the problematic aminocarboxylic acid and silver thiosulfate complex are removed, and reticulation and discoloration of the cyan dye are caused. Was not found to increase.

Although the reason for this has not been elucidated technically accurately, monovalent ions such as ammonium, potassium, and sodium remain in permeated water in a reverse osmosis membrane treatment using this membrane, and the photosensitive material is This is presumed to suppress the change in film quality during drying due to the film swelling and the pH of the film after treatment.

Also, in the reverse osmosis membrane treatment in the present invention, the reverse osmosis membrane used has a lower NaCl rejection rate than that conventionally used, so that the operating pressure can be low and the pump generates heat. There is no problem that the liquid temperature rises.

The ferric complex salt concentration does not increase and the yellow stain does not increase.
For this reason, the washing water and the stabilizing solution can be greatly reduced.

In addition, there is no occurrence of reticulation, and the fading of the cyan dye does not increase. Further, the operating pressure in the reverse osmosis treatment is lower than before, so that the required power is small, and there is no increase in the liquid temperature due to the heat radiation of the pump. And the amount of permeated water can be maintained large.
