Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention comprises a first processing section that processes a silver halide color photosensitive material mainly used for photography, and a first processing section that processes a silver halide color photosensitive material mainly used for printing. The present invention relates to a photographic processing apparatus that integrally includes a second processing section for processing, and a processing method using the same.

Background Art> Silver halide color photosensitive materials (hereinafter referred to as color photosensitive materials) are processed through steps such as color development, desilvering, water washing, and stabilization after exposure. A color developer is used for color development, a bleach solution, a bleach-fix solution, and a fixer solution are used for desilvering treatment, tap water or ion exchange water is used for washing, and a stabilizing solution is used for stabilization treatment. The temperature of each processing solution is usually adjusted to 30 to 40 DEG C., and the color photosensitive material is immersed in these processing solutions to be processed.

Color photosensitive materials include color photosensitive materials for photography, such as color negative film and color reversal film;
Color paper, color reversal vapor, and color photosensitive materials for printing, such as color autopositive paper.

These color photosensitive materials have traditionally been processed only in large-scale photo labs, but with the recent development of small-scale processing systems called minilabs, they are now being processed at photo shops and other stores. There is.

Since these small-scale processing systems are often installed in small stores and the like, it is especially important that the footprint and required work space be small.

For this reason, there is a demand for miniaturization of processing apparatuses such as automatic processors and simplification of processing operations.

On the other hand, in recent years, there has been a demand for environmental conservation and resource saving, and attempts have been made to reduce the amount of processing liquid used and the amount of waste liquid.

For this reason, the present inventor first installed a color negative film processing section and a color paper processing section side by side in order to make the processing device more compact and to reduce the amount of processing liquid replenishment. , an apparatus in which at least a part of the bleach-fix solution after processing color paper flows into a bleach-fix solution for color negative film, and in addition to this,
Furthermore, they have proposed an apparatus in which at least a part of the washing liquid after processing the color negative film is used by flowing it into the washing liquid for color vapor (Japanese Patent Application No. 63-323881, No. 63-325519). We have also proposed a type of device in which two processing sections are stacked to process different types of photosensitive materials (Japanese Patent Application No. 01-9
No. 0549>.

Furthermore, related to these, there is a method in which the desilvering step is separated into a bleaching step and a fixing step, and at least a part of the fixing solution after processing the color paper flows into the fixing solution for color negative film. It is also proposed to remove silver elements and halogen elements from at least a part of a processing liquid having a fixing ability after processing a film, and to flow this liquid into a processing liquid having a fixing ability for color vapor. There is. (Patent Application No. 01-191183).

In addition, in a so-called integrated photographic processing device consisting of a color negative film processing machine and a color vapor processing machine as described above, each processing machine has the same processing tank configuration, size, and shape. , some proposals have been made in which the processing solution is shared by image processing machines (Japanese Patent Application No. 01-212
No. 790).

<Problem to be solved by the invention> Since silver iodobromide emulsions are mainly used in color photosensitive materials for photography, such as color negative films,
Generally, the desilvering process involves bleaching, bleach-fixing and fixing, or bleaching and bleach-fixing.

On the other hand, color photosensitive materials for printing, such as color paper, usually employ a bleach-fixing process.

As described above, it is desirable to reduce the amount of a processing solution having desilvering ability used for both types of sensitive materials, which usually require different processing bath numbers and processing steps.

In particular, when using the combination of desilvering processes shown above for both photosensitive materials, it is better to reuse the processing solution used for the color photosensitive material for photography as the processing solution for the color photosensitive material for printing. This is often advantageous in terms of reducing the amount of liquid used.

However, according to the present inventor, the processing solution having desilvering ability after processing a color negative film contains halide ions (I-Br-) etc. eluted from the film, and after this processing, It has been confirmed that if color paper is processed directly with this solution, desilvering failure will occur and good photographic properties will not be obtained.

Therefore, as mentioned above, the present inventor has proposed desilvering color paper by removing halogen elements and the like (Japanese Patent Application No. 0F-191183).

However, performing such an operation is complicated, as it is necessary to install a means for removing the halogen element in the treatment tank.

Therefore, it is desired to reduce the amount of processing liquid having desilvering ability by a simple method.

The present invention provides a treatment having a desilvering ability after processing a first silver halide color light-sensitive material in which the silver halide emulsion coated on a support has an average silver iodide content of 3 mol% or more. By using the solution to process a second silver halide color light-sensitive material having an average silver iodide content of less than 3 mol%, the amount of the processing solution having desilvering ability used can be reduced. It is an object of the present invention to provide a photographic processing device and a processing method that can obtain good photographic performance even when the photographic image is used in parentheses.

<Means for Solving the Problems> In order to achieve the above object, the present invention has the following configuration (1).
) (2).

(1) First and second processing sections each having a color developing tank, a processing tank with desilvering ability, and a cleaning tank are integrally provided, and the halogenation coated on the support in the first processing section is A first silver halide color light-sensitive material in which the average content of silver iodide in the silver emulsion is 3 mol % or more is processed, and the silver halide emulsion coated on the support is iodized in a second processing section. A photographic processing apparatus for processing a second silver halide color light-sensitive material having an average silver content of less than 3 mol%, the first processing section having at least one processing tank having a desilvering ability. At least a portion of the liquid and at least a portion of the liquid in at least one of the cleaning tanks of the first and second processing sections are transferred to at least one desilvering device of the second processing section. What is claimed is: 1. A photographic processing apparatus characterized in that the photographic processing apparatus is configured to allow water to flow into a processing tank.

(2) Using the photographic processing apparatus according to claim 1, after the exposed first silver halide color photosensitive material is processed in the first processing section, the first silver halide color photosensitive material is processed. A photographic processing method comprising: performing printing exposure on a second silver halide color light-sensitive material; and then processing the second silver halide color light-sensitive material in the second processing section.

<Function> According to the present invention, a first silver halide color photosensitive material (mainly, The average silver iodide content of the silver halide emulsion coated on the support from the first silver halide color light-sensitive material after this processing is A second silver halide color photosensitive material containing less than 3 mol % (mainly a color photosensitive material for printing) is subjected to printing exposure, and the second silver halide color photosensitive material after the printing exposure is transferred to a second processing section. , the first and second processing sections are integrally provided, and at least one
A state in which at least a part of the processed solution in a processing tank having two desilvering capabilities is diluted with at least a part of the solution in at least one of the washing tanks included in the first and second processing sections. Since the desilvering process is carried out while flowing the silver into the processing tank having at least one desilvering ability of the second processing section, there is no occurrence of desilvering defects in the second silver halide color light-sensitive material. , and the amount of processing liquid having desilvering ability used can be reduced.

In particular, the desilvering process of the first silver halide color light-sensitive material is a three-step process of bleaching, bleach-fixing, and fixing, while the second
The desilvering step of the silver halide color light-sensitive material is referred to as a bleach-fixing step, and at least a portion of the bleach-fix solution after processing in the bleach-fix tank for the first silver halide color light-sensitive material is It is preferable that the solution be diluted with washing water in at least one of the washing tanks adjacent to the downstream side of the fixing tank for the silver halide color light-sensitive material and the bleach-fixing tank for the second silver halide color light-sensitive material.

By combining such processing steps, it is possible to efficiently reduce the amount of the processing solution having desilvering ability, and the obtained photographic performance is also good.

Specific composition> Hereinafter, a specific configuration of the present invention will be explained in detail.

1a, 1b, and 1c show a photographic processing apparatus (hereinafter abbreviated as the apparatus) of the present invention for processing silver halide color photosensitive materials (hereinafter also referred to as photosensitive materials).
An example configuration is shown.

The processing method of the present invention is implemented by applying such an apparatus, for example, and will be described below with reference to the drawings.

FIG. 1a shows a plan view of the apparatus, and FIGS. 1b and 1c are cross-sectional side views of the first processing section and the second processing section of FIG. 1a, respectively.

The illustrated apparatus is a first color photosensitive material for processing a color negative film as a first color photosensitive material in which the average content of silver iodide in a silver halide emulsion coated on a support is 3 mol % or more.
and a second processing section 20 that processes color vapor as a second color photosensitive material in which the silver halide emulsion coated on the support has an average silver iodide content of less than 3 mol%. are arranged integrally in parallel.

Further, the illustrated apparatus is equipped with a printer, which can perform all processes such as developing color negative film, printing and exposing color paper from color negative film, and developing color paper.

The first processing section 10 includes a developing tank 11 filled with a color developing solution 110, a bleaching tank 12 filled with a bleaching solution 120, a bleach-fixing tank 13 filled with a bleach-fixing solution 130, and a washing tank 15 filled with washing water W. .16, it has a stabilizing tank 17 filled with a stabilizing solution 170 and a drying chamber 18, and the color negative film S is subjected to color development - bleaching - bleaching - fixing - fixing - first washing - second washing - stabilization - drying. Each process is performed.

On the other hand, the second processing section 20 includes a printer section 28 that prints and exposes the color paper P from the color negative film S after the development process, a reservoir 29, a developer tank 21 filled with a color developer 210, and a bleach-fix solution 220. Bleach-fix tank 2
2. It has a washing tank 23, 24, 25 filled with washing water W and a drying chamber 26, and the color vapor P after printing exposure is subjected to color development - bleach fixing - first washing - second washing -> third washing - drying. Each process is performed.

In FIG. 1C, only the color vapor P is shown in the printer section 28, and the color negative film S is omitted.

In addition, in the first processing section 10, a developing tank 11, a bleaching tank 1
2. Replenishment tanks are installed in the fixing tank 14, the cleaning tank 1613, and the stabilization tank 17. In addition, the second processing unit 20
Here, replenishment tanks are installed in the developer tank 21 and the cleaning tank 25 (both are not shown).

Furthermore, as shown by the arrow in FIG. 1a, during processing, the entire overflow of the bleaching tank 12 and the fixing tank 14 flows into the bleach-fixing tank 13 as the tank is refilled. The entire overflow of the fixing tank 13 is configured to flow into the bleach-fixing tank 22 as a replenisher.

That is, in the above example, the entire amount corresponding to the replenishment amount is overflowed.

At this time, the overflow of the bleach-fixing tank 13 is diluted by the entire amount of overflow of the first washing tank 23 that flows into the bleach-fixing tank 22 from the first washing tank 23 adjacent to the downstream side of the bleach-fixing tank 22. It will flow into the fixing tank 22. In this case, the overflow of the bleach-fix tank 13 is preferably diluted 1.5 to 4 times, more preferably 1.7 to 2.5 times.

After processing a color negative film, the bleach, bleach-fix and fixer contain B eluted from the color negative film.
It contains substances that inhibit desilvering, such as halide ions such as r-T-.

Therefore, the overflow flowing into the bleach-fix tank 22 for color paper contains a large amount of the above desilvering inhibiting substances, and if used as is, desilvering defects will occur in the color paper.

However, in the present invention, since the overflow of the first cleaning tank 23 adjacent to the downstream side is used for dilution as described above, no desilvering failure occurs in the color paper.

Also, it is preferable to dilute it 1.5 to 4 times, but if the dilution is less than 1.5 times, the dilution of halide ions, etc. will not be sufficient, and desilvering failure will likely occur. This is because diluting more than 4 times will not only waste water, but will also result in insufficient bleach and fixing agent content that contribute to desilvering, resulting in poor desilvering. It is from.

Therefore, the effect of the present invention is increased by diluting it by 1.5 to 4 times.

In the present invention, the I concentration present in the bleach-fix solution for color paper during processing is 0.
The range is 0.01 to 0.2 g/l.

Between the first and second washing tanks 15.16 for color negative films and the first, second and third washing tanks 23.24 for color paper, as indicated by the arrows in FIG. 1a.
．． A multistage countercurrent system is adopted for each of the 25 spaces.

Further, the entire overflow of the first cleaning tank 15 for color negative film is configured to flow into the first cleaning tank 23 for color paper as a replenisher.

That is, the entire amount corresponding to the amount of replenisher refilled in the second cleaning tank 16 for color negative film overflows from the first cleaning tank 15.

Note that the cleaning water W in the first cleaning tank 15 installed adjacent to the downstream side of the fixing tank 14 contains the fixing agent brought in from the fixing tank 14, and this overflow flows into the first cleaning tank for color paper. 23, which also flows into the bleach-fix tank 2.
2, the coloring of the emulsion film surface of the color paper P by the bleaching agent is reduced, and the cleaning efficiency is improved. Therefore, the amount of replenishment of washing water for color paper can also be reduced.

In the present invention, there is no need to newly prepare a replenisher for the bleach-fixing solution in the second processing section, and the overflow of the bleach-fixing tank in the first processing section can be used as is. Therefore, the amount of replenishment of the processing solution having desilvering ability for the bleach, bleach-fix and fix solutions in both parts can be reduced by 40 to 80% compared to the conventional method.

Furthermore, by providing the liquid flow as shown in FIG. 1a, the total replenishment amount can be reduced by 15-50%.

In addition, the above-mentioned inflow and outflow of the liquid may be carried out naturally by overflow, or may be carried out forcibly by a pump.

In the present invention, it is preferable for the inflow and outflow of the liquid to be as shown in FIG. 1a in order to save water usage, but it may be as shown in FIG. 2. .

FIG. 2 shows a fixing tank 14 adjacent to the upstream side of the first cleaning tank 15, in which the overflow of the first cleaning tank 15 for color negative film does not flow into the first cleaning tank 23 for color paper. The only major difference is that it flows into

Therefore, the overflow of the first cleaning tank 15 is caused by the overflow of the fixing tank 14.
The overflow of the fixing tank 14 will flow into the bleach-fixing tank 13, and the overflow of the bleach-fixing tank 13 will be diluted by the overflow of the first washing tank 15 via the fixing tank 14.

In this case, part or all of the overflow from the first washing tank 23 for color paper may be flowed into the bleach-fixing tank 22, as indicated by the dotted line arrow in the figure, and diluted preferably within the above range. good.

Alternatively, the liquid may be caused to flow in and out as shown in FIG.

FIG. 3 is similar to FIG. 1 except that no overflow is allowed to flow in and out between the first and second washing tanks 23 and 24 for color paper.

Therefore, the overflow will be discharged from the second cleaning tank 24, and the first cleaning tank 15 for color negative film will be discharged.
The overflow is the first cleaning tank 23 for color paper.
This contributes to the dilution of the bleach-fix solution through this process.

In addition, in order to restore the oxidizing power of the bleach during processing, the bleach-fix solution for color paper is manufactured using JP-A No. 63-2517.
Pressurized air may be introduced through a vibrator made of a porous material as described in Japanese Patent No. 47.

In either case, in the present invention, the entire amount corresponding to the overflow of a processing tank having desilvering ability for color negative film and the overflow of a cleaning tank adjacent to the processing tank having desilvering ability is directly or indirectly The composition is such that it flows into a bleach-fixing tank for paper films, and it is preferable to do so.

The apparatus of the present invention is not limited to the one shown in FIGS. 1a to 1c, but may have the configuration shown in FIG. 4.

The apparatus shown in FIG. 4 is arranged in a single casing 90 such that a first processing section 30 for developing a color negative film S and a second processing section 40 for developing a color paper P are located one above the other. It is housed integrally in the.

Further, an exposure section 70 for printing and exposing color paper P from color negative film S is installed downstream of the first processing section 30.

Therefore, with this device, development processing of a color negative film, printing exposure from the color negative film to color paper, and development processing of the color paper can be performed in an integrated manner.

As shown in the figure, the first processing section 30 includes a developer tank 31. It has a processing tank having a desilvering ability (hereinafter referred to as a desilvering processing tank) 32 filled with a processing solution having a desilvering ability, a washing tank 33 filled with washing water, and a drying chamber 34, and is used for color development on a color negative film S. →The steps of desilvering, washing, and drying are performed.

The exposure section 70 located downstream of the first processing section 30 includes an exposure lamp 71, a mirror 72 for reflecting the light from the exposure lamp 71 and applying it to the color negative film S, and an exposure section 70 that converts the image of the color negative film S into a color paper P. It has a slit 73 and a lens 74 for projecting images onto a color paper P from a color negative film S after development.

Note that the color paper is stored in a roll in the magazine 80, and is cut as appropriate with a cutter or the like.

On the other hand, the second processing section 40 has a developing tank 41 filled with a color developing solution, a bleach-fixing tank 42 filled with a bleach-fixing solution, a washing tank 43 filled with washing water, and a drying chamber 44. The process of color development, bleach-fixing, washing, and drying is then carried out.

As shown in FIG. 5, the desilvering treatment tank 32 applied to the first treatment section 30 is divided into a plurality of treatment chambers, each of which is sequentially connected through a narrow passage. As the color negative film S passes through these processing chambers and narrow passages, the desilvering process is performed.

As shown in the figure, the desilvering treatment tank 32 includes treatment chambers 32A, 32
B, 32G, 32D, 32E.

It has seven processing chambers 32F and 32G, and a narrow passage is provided between each of these processing chambers.
Furthermore, narrow passages for carrying in or out the color negative film are also provided in the upper parts of the processing chambers 32A and 32G.

A liquid supply port (not shown) is installed in each of the processing chamber 32A and the processing chamber 32G, and a liquid drain port is installed in the intermediate processing chamber 32D.

In addition, in order to maintain the liquid level L in the processing chamber 32D, the drain port in the processing chamber 32D is provided so as to be located at the upper part of the tank via a connecting pipe, as shown in the figure.

The above-mentioned processing chamber and passage are usually formed using a block body.

Note that the block body, the conveyance roller for conveying the color negative film, the guide, etc. are omitted from FIG. 5.

Details of such a treatment tank are described in Japanese Patent Application No. 01-99855 filed by the present applicant.

When starting the process using the above-mentioned desilvering tank, the bleaching solution R3 is supplied from the supply port of the processing chamber 32A, and the fixing solution R2 is supplied from the supply port of the processing chamber 32G, as shown by the arrows in the figure. , respectively.

During processing, such supply continues as supply of replenisher, and overflow OF is drained from a drain port provided in the processing chamber 32D.

By supplying and draining the liquid in this manner, each of the processing chambers 32A to 32G contains a processing liquid having substantially the following desilvering ability.

Processing chamber 32A (first chamber)...Bleach solution processing chamber 32B (second chamber)...Bleach-fixing solution processing chamber 32C (third chamber)...Bleach-fixing solution containing many bleaching solution components Solution processing chamber 32D (4th chamber)...Bleach-fix solution processing chamber 32E
(5th chamber)...Bleach-fix solution processing chamber 32F (6th chamber) containing many bleaching solution components...Bleach-fixing solution processing chamber 32G (7th chamber) containing many bleaching solution components...Fixer As mentioned above, the reason why a processing solution with desilvering ability can be stored in each processing chamber is that when color negative film is not processed, there is almost no flow of solution between adjacent processing chambers, and during processing, So that there is only a small distribution,
This is because appropriate shielding means and the like are installed in each processing chamber. Details of such shielding means are described in Japanese Patent Application No. 01-27034 filed by the present applicant.

Here, "there is almost no flow" means that the amount of movement of the processing liquid between processing chambers is so small that it can be ignored, for example, the amount of movement of the processing liquid is 2 mj/min or less. This refers to cases where

In addition, "there is only a small amount of flow" means that the amount of processing liquid transferred between processing chambers is about the same amount as the supply amount of replenisher or less than that, for example, the amount of processing liquid transferred is 1 to 1. 2
Preferably, the speed is 0 mj/min.

At this time, the bleaching solution moves in the same direction as the color negative film transport direction (parallel flow), and the fixing solution moves in the opposite direction (counterflow).

In this way, the bleaching efficiency is improved by making the flow of the bleaching solution a parallel flow.

Furthermore, the flow of the fixing solution is referred to as a counterflow, but in the bleaching/fixing process, only fixing progresses in the unexposed and undeveloped areas, and in the developing areas, bleaching progresses first and then fixing progresses. From the viewpoint of processing efficiency, it is preferable to perform a substantial bleaching process in the processing chamber 32A (first chamber) and a substantial fixing process in the processing chamber 32G (seventh chamber).
Rather, processing efficiency is improved. Furthermore, since the above desilvering process can be performed with a desilvering tank with only one tank, the time required for crossover between processing tanks ( In-flight time) is virtually unnecessary, and the overall processing time can also be shortened.

Furthermore, the processing chamber 32G in the desilvering treatment tank 32 before reaching the washing tank 33 substantially contains the fixing solution and does not contain a bleaching agent component, so that the washing load is significantly reduced.

As described above, bleaching can be performed in at least the first processing chamber, fixing can be performed in at least the last processing chamber, and bleach-fixing can be performed in the intermediate processing chamber with a drainage port. can be applied.

In addition to such bleaching, bleach-fixing, and fixing processes, the intermediate processing chamber other than those mentioned above stores a bleach-fix solution similar to a bleach solution and a bleach-fix solution similar to a fix solution. Therefore, desilvering treatment using such a treatment liquid is also possible.

Therefore, it is possible to perform a desilvering process that includes at least the steps of bleaching-bleaching@→fixing.

The improvement in processing efficiency is also due to the fact that there is no contact between the color negative film and the atmosphere during processing.

In the illustrated example, there are seven processing chambers, and the fourth chamber (processing chamber 3
2D), but depending on the purpose,
It is also possible to select a treatment step as appropriate by changing the number of treatment chambers and the treatment chamber in which the drain port is installed.

In addition, the volume per processing chamber is 20 to 3000 mj,
Preferably, it is about 60 to 900 ffi1.

As shown in FIG. 4, during processing, the overflow OF of the bleach-fix solution discharged from the fourth chamber in the desilvering tank 32 for color negative film is completely transferred to the bleach-fix tank 42 for color paper. is flowing into the country. and,
The entire amount of the overflow from the washing tank 43 adjacent to the downstream side of this tank 42 flows into this bleach-fixing tank 42 as a replenisher, whereby the overflow OF is preferably diluted within the above-mentioned range. It happens.

The cleaning tank 33 applied to the first processing section 30 and the cleaning tank 43 applied to the second processing section 40 are essentially different in structure from the desilvering processing tank described above. Instead, it is divided into a plurality of processing chambers, each of which is successively connected by a narrow passageway.

In FIG. 6, the cleaning tank 33 is shown.

The cleaning tank 33 differs from the desilvering tank shown in FIG. 5 in its configuration only in the installation positions of the liquid drain port and the liquid supply port.

The cleaning tank 33 has seven processing chambers 33A to 33G, and a final processing chamber 33 as shown by the arrow in the figure.
A stabilizing solution or its replenisher R1 is supplied from G (7th chamber), washing water W is supplied from the processing chamber 33F, and the processing chamber 33A (
The overflow OF is discharged from a drain port installed in a narrow passage connected to the first chamber for carrying in the photosensitive material.

The details of such a treatment tank are described in Japanese Patent Application No. 01-27034, No. 01-25132, No. 01-61707 filed by the present applicant.

In the washing process in the washing tank 33 having such a configuration, the washing water flows in the opposite direction to the conveyance direction of the color negative film (counter flow).

Because of this flow, and because the amount of liquid transferred in each processing chamber is the same as that in the desilvering treatment tank 32, the ratio of the concentration of chemicals, etc. carried by the color negative film in each processing chamber is maintained. Therefore, the freshness of the washing water W in the processing chamber 33F is maintained, and the washing efficiency is improved.

This improvement in washing efficiency is partly due to the fact that there is no contact between the color negative film and the atmosphere during processing.

By improving the washing efficiency in this way,
The amount of replenishment of washing water can be reduced.

Further, by using the cleaning tank 33 having such a configuration, the stabilization process can be performed in the same tank.

Further, the stabilizing liquid moves from the processing chamber 33G to the processing chamber 32F, but this is rather preferable in terms of obtaining good photographic properties.

The OF2 discharged from the first chamber of the color negative film cleaning tank 33 flows into the color paper cleaning tank 43, as shown in FIG.

This cleaning tank 43 differs from the cleaning tank 33 described above only in the number of processing chambers and the installation position of the liquid supply/drainage ports, but there is essentially no difference in its configuration.

This device has 11 processing chambers, and wash water is supplied from a final processing chamber 43K, OF2 is supplied from a processing chamber 43B (second chamber), and the sensitive material is connected to a processing chamber 43A (first chamber). The liquid is configured to overflow from a drainage port installed in a narrow passageway for delivery.

By introducing OF into the processing chamber 43H of the washing tank 43, washing water containing a large amount of fixing agent components is introduced, similar to that in FIG. Since the water flows into the water, the effect of improving the washing efficiency can be obtained.

In addition, the cleaning tank 43 has the same effect as the cleaning tank 33 by maintaining the concentration ratio of the chemicals brought in by the color vapor in each processing chamber.

Similarly to the apparatus shown in FIG. 1, in the apparatus having such a configuration, there is no need to prepare a new bleach-fixing solution replenisher for the second processing section. Furthermore, as described above, the desilvering efficiency is improved and the desilvering treatment time is shortened due to the structural characteristics of the desilvering treatment tank for the first processing section.

For this reason, the amount of replenishment of the processing solution having desilvering ability can be reduced by 30 to 80% in both parts compared to the conventional method.

Also, the total replenishment amount can be reduced by 10-40%.

Even in the device having such a configuration, the directions of inflow and outflow of the liquid are not limited to those shown in the drawings, and may be varied within the scope of the present invention as described above.

For example, in the present invention, the overflow of a cleaning tank for color negative film may be directly allowed to flow into a bleach-fixing tank for color paper.

In addition, in the present invention, various combinations of treatment tanks can be employed in the first and second treatment sections according to the treatment process, and any combination may be used as long as it does not depart from the scope of the present invention. Good too.

In the first color light-sensitive material of the present invention, the silver halide emulsion coated on the support has an average silver iodide content of 3.
It is more than mol % and mainly applies to color photosensitive materials for photographing, and representative examples include color reversal films in addition to the above-mentioned color negative films.

Among these, color negative film is for normal processing (negative processing), and color reversal film is for reversal processing (
It is for auto-positive processing). Furthermore, both of these are negative color photosensitive materials.

On the other hand, the second color photosensitive material is one in which the average content of silver iodide in the silver halide emulsion is less than 3 mol%, and is mainly a color photosensitive material for printing. Auto positive color paper Examples include color reversal paper and color positive film.

Among these, color paper, auto-positive color paper, and color-positive film are for normal processing (negative processing), and color reversal paper is for reversal processing (auto-positive processing). Furthermore, color paper, color reversal paper, and color positive film are negative color photosensitive materials, and autopositive color paper is an autopositive color photosensitive material.

In addition to the above color negative film and color paper, combinations of color photosensitive materials to which the present invention can be applied include a color reversal film as the first color photosensitive material and a color reversal paper as the second color photosensitive material. can be mentioned.

However, in the reversal process, the first
It is necessary to install a developing tank, a washing tank, and in some cases a reversing bath.

To illustrate such processing steps, for a color reversal film, the steps are first development -> first washing - reversal, one color development - bleaching and fixing -> second washing - third washing - stabilization -> drying,
Examples of color reversal paper include those in which the steps are first development, first washing, reversal exposure, color development, second washing, mill fixation, third washing, and drying.

In such a process, the direction of inflow and outflow of the liquid in the desilvering process and the water washing process can be indicated by, for example, the arrows below.

Color reversal film: Even in such a process, the same effects as described above can be obtained.

Further, in the above step, it is also preferable that the overflow of the bleaching tank for color reversal film flows into a fixing tank, and the overflow of this fixing tank flows into the bleaching tank for color reversal paper.

As shown in the drawings, the present invention is preferably applied to an apparatus that consistently performs development processing of a color negative film, printing exposure from the color negative film to color paper, and development processing of the color paper. Processing area ratio (s

Note that in the present invention, the first and second processing sections are both configured to operate even when only one of the first and second color photosensitive materials is processed in either processing section. It is preferable to do so.

In the above description, the desilvering step is a combination of bleach-bleach-fixing and bleach-fixing, or a combination of bleach-fixing and bleach-fixing, but is not limited to these.

In addition, preferred examples include those in which the first color light-sensitive material is subjected to bleaching and then bleach-fixing, and the second color light-sensitive material is subjected to a bleach-fixing process.

In this case, it is preferable that the overflow of the bleaching tank flows into the bleach-fixing tank, and the overflow of the bleaching-fixing tank for the first color light-sensitive material flows into the bleach-fixing tank for the second color light-sensitive material.

It shall include a tank, specifically,
In addition to the above-mentioned washing tank, examples of the former treatment tank include a rinsing tank, and examples of the latter treatment tank include a stabilization tank.

However, in some cases, washing is used synonymously with water washing, or is used as a concept that includes water washing and stabilization, but the liquid that dilutes the processing solution with desilvering ability is washing water or something similar to this. It is synonymous with washing water, and what is generally called a stabilizing liquid is not used.

In the present invention, it is preferable that the washing step of the first color photosensitive material includes a washing step with so-called washing water, and this washing step is preferably the next step after the fixing step.

Further, in the second color light-sensitive material as well, it is preferable that the washing water includes a washing step, and this washing step is preferably the next step after the bleach-fixing step.

In this processing 1A, good photographic performance was obtained for all color vapors.

In the treatment IA, the treatment was carried out using the integrated treatment apparatus shown in FIGS. 1a to 1C.

Note that the tank capacity etc. in this device are the same as those in Process IA.

However, the flow of overflow between each type is
As shown in the figure, the overflow of the first cleaning tank for color vapor is discharged without flowing into the bleach-fixing tank for color vapor.

In this way, the development processing of color negative film, printing from color negative film to color vapor, and development processing of color vapor were consistently performed under the conditions that the color developing solution was replaced five times in the developing tank for color negative film. .

The treatment area ratio was the same as treatment IA.

Such processing is referred to as processing 1B.

Good photographic performance was obtained for all color vapors during continuous processing.

Furthermore, by adopting the flow of the solution as shown in FIG. 2, a new replenisher for the bleach-fix solution for color vapor was not required, and the total replenishment amount was reduced by 15% when compared with Process IA.

In addition, the overflow flowing into the bleach-fix tank for color vapor during continuous processing is diluted 1.86 times (referred to as dilution 1.86), and the bleach-fix solution in this bleach-fix tank is The I-concentration of is 0.10 in terms of KI.
It was maintained at ~0.15 g/j.

In Process 1B, 30% of the overflow of the first washing tank for color vapor is further flowed into the bleach-fixing tank for color vapor and processed through the porous material by the method disclosed in JP-A-63-251747. The same process was carried out except that compressed air was introduced into the bleach-fix solution for color vapor.

This is referred to as processing 1C.

In all cases, color prints with good photographic performance were obtained.

Total replenishment was reduced by 15% compared to Process IA, and the dilution of the overflow into the color vapor bleach-fix tank was 2.67. Moreover, the -concentration was 0.07 to 0.105 g # in terms of KI.

In Processing IB, the flow of overflow between each type is as shown in Figure 3, and the process is the same except that the replenishment amount of cleaning water for color vapor is reduced to 30% and overflow is made from the second cleaning tank. processed. This is called processing 1D.

Even with this method, the photographic performance of all color prints was good, and no poor water washing occurred. The reason for the improved washing efficiency is thought to be that the overflow of the first washing tank for color negative film was indirectly introduced into the bleach-fixing tank for color vapor, increasing the amount of fixing components.

The total replenishment amount was reduced by 38% compared to the treated 1A, the dilution was 1.86, and the concentration of - was 0.1 in terms of KI.
It was 0 to 0.15 g/l.

In process 1B, the overflow flow is as shown in Figure 1a, the replenishment amount of wash water for color vapor is reduced to 15%, and the bleach-fix solution for color vapor is pressurized in the same manner as process IC. The treatment was carried out in the same manner except that air was introduced. This is called a processing IE.

Even with this method, the photographic performance of the color prints was good, and no poor water washing occurred.

The total replenishment amount was reduced by 43% compared to treatment 1B, the dilution was 2.27, and the concentration of I'' was O, Oa in terms of KI.
It was ~0.13g/j.

When the overflow of the water-washed portion was stopped and the dilution degree was set to 1 (non-diluted state), desilvering failure occurred and color prints with good photographic performance could not be obtained.

The I-concentration at dilution level 1 is 0.2 to 0.30 g/in terms of KI.
It was j.

Furthermore, it was confirmed that when the film was processed at a dilution level of 4.5, desilvering failure occurred, possibly due to excessive dilution, and sufficient photographic performance could not be obtained.

Example 2 In the processing IA of Example 1, the overflow flow shown in the figure was processed using the integrated processing apparatus shown in FIG.

The volume of each processing chamber in the desilvering treatment tank for color negative film was 450 ml, and the number of processing chambers was 7 (tank capacity: 3.2° C.).

In addition, there were 7 cleaning tanks with a pressure of 360 mN per room (tank capacity 2.6β), and 11 washing tanks with a pressure of 250 m1 per room for color paper.
(tank capacity 2.8β).

By applying such a treatment tank, first, the amount of replenishment of each treatment liquid could be reduced as follows.

The other processing tanks used were the same as in Example 1 (tank capacity of bleach-fixing tank for color paper: 17β).
.

color negative film Bleach solution 20% Fixer 50% Washing water 50% Stabilizing liquid 33% color paper Washing water 90% Such processing is referred to as processing 2E.

Even in this manner, color prints with good photographic performance were obtained.

The total replenishment amount was reduced by 58% compared to the treatment IA of Example 1, the dilution was 3, and the knee concentration was 0.12 in terms of KI.
It was ~0.19.

Example 3 In the processing IA of Example 1, JP-A-01-10605
Sample 101 (color reversal film) described in Example 1 of Publication No. 0 and color reversal paper of Example 2 of Japanese Patent Application No. 63-261353 were used in the following processing steps.

Color prints with good photographic performance were obtained in such processing.

Note that the treated area ratio was the same as in Example 1.

In processing 3A, a processing apparatus similar to the processing apparatus shown in FIGS. 1a to 1C was used, and the overflow flow was processed as follows.

In addition, the abbreviations are used.

■ Overflow of H5 flows into H6.

■ Part of the overflow of W2 (for color reversal film) (41mj/135 size 36 shots)
Inflow to 6.

■ Overflow of H6 flows into HF2.

This is called processing 3B.

Even in this manner, good photographic performance was obtained with the color reversal paper.

The total amount of replenishment excluding the washing water is about 14% lower than that in treatment 3A, the dilution level is 2, and the -concentration of HF2 is 0.08 to 0.0 in terms of KI. 1E5g/l.

In Process 3B, the following overflow flow was processed.

■ Overflow of H5 flows into H6.

■ Overflow of H6 flows into HF2.

■W3 (for color reversal paper) flows into HF2 at a rate of 220mj per 1m''.

This is referred to as processing 3C.

Even in this manner, good photographic performance was obtained.

The total replenishment amount of chemical solution excluding washing water is approximately 1 compared to treatment 3A.
The dilution is 4%, the dilution is 3.15, and the I” of HF2 is reduced by 4%.
The concentration was 0.05 to 0.10 g/l in terms of KI.

In Process 3C, the following conditions were further added.

■ Overflow of Hl flows into HPI and HPI
The replenishment amount is 1/2.

■ The overflow of H3 flows into HF2, and the replenishment amount of HF2 is reduced to 1/2.

This is called processing 3D.

Even in this manner, good photographic performance was obtained.

The total replenishment amount was reduced by 45% compared to treatment 3A.
