Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a photographic material processing apparatus for forming an image on the photographic material by immersing a silver halide color photographic material after exposure in a processing solution, and more specifically, it relates to a processing bath for forming an image on the photographic material. The present invention relates to a photographic material processing apparatus in which processing liquid therein is well stirred.

(Prior Art) In recent years, there has been a growing demand for higher efficiency and higher productivity in the processing of color photographic materials. This tendency is particularly noticeable in the production of color prints, and there is a strong desire to shorten print processing time due to the need for short-term finishing.

As is well known, the process of finishing a color print consists of exposure and color development. While using highly sensitive photosensitive materials leads to shorter exposure times, in order to shorten color development processing time, it is essential to realize a system that combines photosensitive materials that can speed up development with processing solutions or processing methods. It is.

As a technology to achieve these issues, we have developed an emulsion with a high silver chloride content (a high silver chloride emulsion) instead of a silver chlorobromide emulsion with a high silver bromide content, which has been widely used in photosensitive materials for color printing (color photographic paper). For example, International Patent Publication No. WO 37-04534 discloses that a color photographic material containing a high silver chloride emulsion is processed by substantially sulfite ions. and a rapid processing method using a color developer that does not contain Hensyl alcohol.

In addition to the above-mentioned patent, JP-A-61-70552 discloses that a high silver chloride color photographic light-sensitive material is used and a developing solution is added in a replenishing amount to prevent overflow into the developing bath during development. A method for low replenishment is described, and furthermore, in JP-A-63-106655, for the purpose of stabilizing processing, a high silver chloride color photographic light-sensitive material is treated with a hydroxylamine compound and chlorine at a certain concentration or more. A method of processing with a color developer containing ions is disclosed.

In this way, by using a high silver chloride emulsion and devising a developing processing solution, it is possible to develop a film for 3 minutes and 30 seconds using a conventional silver chloride bromide emulsion system (e.g. Fuji Photo Film's Color Processing CP-20).
The development time was shortened from 45 seconds to 45 seconds (for example, the total processing time was 4 minutes using Fuji Photo Film ■'s Color Processing CP-40FMS).

(Intelligence to be Solved by the Invention 8) Generally, when processing a photographic material by immersing it in a processing liquid,
It is preferable that the processing liquid is quickly exchanged on the film surface of the photosensitive material. For example, by providing a stirring means in the processing tank to stir the processing liquid, the processing liquid can be quickly exchanged on the film surface.
are doing.

As a specific stirring means, for example, Japanese Patent Application Laid-Open No. 213534
There is an apparatus described in Publication No. 2, in which a stirring means reciprocates in the vertical direction to stir the processing liquid. The stirring means presses the processing liquid with a surface (horizontal surface) perpendicular to the direction of movement and stirs the processing liquid, so if the width of the photosensitive material is large, the horizontal surface is also lengthened to match the width of the photosensitive material. There is a need. However, if the horizontal plane is lengthened, the processing liquid will not be exchanged well and will remain in the longitudinal center.Therefore, the apparatus described in the above publication is effective for processing small-width photosensitive materials such as negative films. However, for photosensitive materials such as photographic paper, the processing liquid cannot be replaced well.

In particular, when rapidly processing a photosensitive material having a high silver chloride emulsion layer as mentioned above, it is important to incorporate the processing solution into the film at the initial stage of processing, as well as the exchange rate of the processing solution. It is preferable that the mixture be well stirred.

SUMMARY OF THE INVENTION An object of the present invention is to solve the above-mentioned problems, and to provide a photographic material processing apparatus in which a processing liquid is well stirred and the processing liquid is rapidly exchanged on the film surface of a photographic material.

(Means for Solving the Problems) The above-mentioned object of the present invention is to provide a photographic material processing apparatus in which an exposed color photographic material is conveyed vertically in a processing liquid and processed in a horizontal direction within a processing tank. This is achieved by a photographic photosensitive material processing apparatus characterized in that a stirring member that moves back and forth is provided along the width direction of the photosensitive material, and the stirring member has a surface inclined with respect to the direction of movement.

The horizontal movement direction of the stirring member may be perpendicular to the surface of the photosensitive material, or may be parallel to the surface of the photosensitive material.

The inclined surface of the stirring member may have a shape in which peaks and troughs are formed continuously along the width direction of the photosensitive material, or the ridges or troughs may be formed continuously along the width direction of the photosensitive material. The slope may have a formed shape, and the direction of the slope is not limited.

Further, the photographic light-sensitive material processing apparatus having the above-mentioned structure has 95 mol%
This is particularly effective when rapidly processing a color photographic material having at least one layer of a silver halide emulsion containing the above silver chloride. When rapidly processing a photosensitive material containing high silver chloride with a small amount of processing solution, it is necessary to quickly exchange the processing solution on the film surface of the photosensitive material. Since the processing solution is well stirred, development can be carried out in a short time, desilvering can be carried out in a short time, and water washing can be carried out reliably in a short time without unevenness or staining.

Furthermore, by providing a driving means for driving the stirring member at different speeds during forward movement and backward movement, the processing liquid can be exchanged efficiently and stirred better. In order to change the forward movement speed and backward movement speed of the stirring member that moves horizontally, for example, the forward movement speed and backward movement speed of the stirring member are set and driven by the driving means to be different.

The angle of inclination (acute angle) that the above-mentioned inclined surface makes with the direction of movement is 5 to 8.
The angle is preferably about 5°, particularly preferably 10 to 80″.

When the stirring member of the present invention is moved in a direction parallel to the surface of the photosensitive material, sufficient stirring is possible even if the width of the stirring member is smaller than the width of the photosensitive material, which has the advantage of saving space. . Furthermore, in this stirring direction, it is possible to change the moving length of the stirring member depending on the width of the photosensitive material.

As the silver halide used in the present invention, silver chloride, silver bromide, silver (iod)chlorobromide, silver iodobromide, etc. can be used, but especially for the purpose of rapid processing, silver iodide can be used substantially. It is preferable to use a silver chlorobromide or silver chloride emulsion having a silver chloride content of 90 mol % or more, more preferably 95 mol % or more, especially 98 mol % or more.

In the photosensitive material according to the present invention, a hydrophilic colloid layer is incorporated into a hydrophilic colloid layer for the purpose of improving image sharpness, etc.

Simultaneously or singly using a compound that chemically combines with an oxidized form of a color developing agent to produce a chemically inert and substantially colorless compound,
For example, it is preferable to prevent staining and other side effects due to the formation of coloring dyes due to the reaction between the color developing agent remaining in the film or its oxidized product and the coupler during storage after processing.

Furthermore, in order to prevent various types of mold and bacteria that propagate in the hydrophilic colloid layer and cause image deterioration, the photosensitive material according to the present invention is coated with an anti-mold agent as described in JP-A No. 63-271247. It is preferable to add

The support used in the photosensitive material according to the present invention may be a white polyester support for display or a support in which a layer containing a white pigment is provided on the support on the side having a silver halide emulsion layer. May be used. In order to further improve the sharpness, it is preferable to coat an antihalation layer on the silver halide opalescent layer coated side or back side of the support.

In particular, it is preferable to set the transmission density of the support in the range of 0.35 to 0.8° so that the display can be viewed in both reflected light and transmitted light.

The photosensitive material according to the present invention may be exposed to visible light or infrared light, and the exposure method may be low-light exposure or high-light short-time exposure, and especially in the latter case, it is possible to expose the photosensitive material to visible light or infrared light. Laser scanning exposure systems with exposure times shorter than 10-' seconds are preferred.

Further, during exposure, it is preferable to use a band stop filter as described in US Pat. No. 4,880,726, which eliminates light color mixture and significantly improves color reproducibility.

Exposed photosensitive materials can be subjected to color development processing, but

It is more preferable that the developer used in the present invention does not substantially contain sulfite ions. The sulfite ion functions as a preservative for the developing agent, and at the same time has the effect of dissolving silver halide and reacting with the oxidized product of the developing agent to reduce the dye formation efficiency.

It is more preferable that the developing solution used in the present invention contains kabo koji in place of the hydroxylamine and sulfite ion.

The term "organic preservative" as used herein refers to any organic compound that reduces the rate of deterioration of an aromatic primary amine color developing agent when added to a processing solution for a color photographic light-sensitive material. That is, they are organic compounds that have the function of preventing color developing agents from being oxidized by air, among others, hydroxylamine derivatives (excluding hydroxylamine, the same shall apply hereinafter), hydroxamic acids, hydrazines, hydrazides, phenols, Especially α-hydroxyketones, α-aminoketones, sugars, monoamines, diamines, polyamines, quaternary ammonium salts, nitroxy radicals, alcohols, oximes, diamide compounds, fused cyclic amines, etc. It is an effective organic preservative.

The fixing agent used in the bleach-fixing solution or fixing solution is a known fixing agent, namely, a periosulfate such as sodium periosulfate or ammonium thiosulfate; a thiocyanate such as sodium thiocyanate or ammonium thiocyanate; These are water-soluble silver halide dissolving agents such as glycolic acid, thioether compounds such as 36-cythia-138-octanediol, and thioureas, and these can be used alone or in combination of two or more.

Further, a special bleach-fixing solution consisting of a combination of a fixing agent and a large amount of a halide such as potassium iodide as described in JP-A-55-155354 can also be used. In the present invention, the use of thiosulfates, particularly ammonium thiosulfates, is preferred.

The amount of fixing agent per 11 is preferably from 0.2 to 2 mol, more preferably from 0.3 to 1.0 mol. The pFI range of the bleach-fix solution or fix solution is preferably 3 to 9, more preferably 4 to 8.

Further, the bleach-fix solution may contain various other optical brighteners, antifoaming agents, surfactants, and organic solvents such as polyvinylpyrrolidone and methanol.

Bleach-fix solutions and fixing solutions contain sulfites (e.g., sodium sulfite, potassium sulfite, ammonium sulfite, etc.) and bisulfites (e.g., ammonium bisulfite, sodium bisulfite, potassium bisulfite, etc.) as preservatives.
, metabisulfite (eg, potassium metabisulfite, sodium metabisulfite, ammonium metabisulfite, etc.).

These compounds are approximately 0.02 to 0.02 in terms of sulfite ion.
The content is preferably 1.0 mol/2, more preferably 0.04 to 0.6 mol/l.

Sulfites are commonly added as preservatives, but other preservatives include ascorbic acid, carbonyl bisulfite adducts,
Alternatively, a carbonyl compound or the like may be added.

Furthermore, buffering agents, optical brighteners, chelating agents, antifoaming agents, antifungal agents, etc. may be added as desired.

After desilvering treatment such as fixing or bleach-fixing, washing with water and/or stabilization treatment is generally performed.

The amount of washing water in the washing step can be set over a wide range depending on the characteristics of the photosensitive material (for example, depending on the materials used such as couplers), the intended use, the washing water temperature, the number of washing tanks (number of stages), and various other conditions. Among these, the relationship between the number of flushing tanks and the amount of water in the multistage countercurrent method is described in the Journal on the Society.
On Mosicon Picture and Television Engineers (Journal of the 5
Ociety of MotionPicture a
It can be determined by the method described in nd Te1vision Engineers, Vol. 64, ρ, 248-253 (May 1955 issue). Generally, the number of stages in the multistage countercurrent system is preferably 2 to 6, particularly preferably 2 to 5.

According to the multi-stage countercurrent method, the amount of water used for washing can be greatly reduced, and for example, the amount of water used for washing photosensitive materials can be reduced significantly. 500 Id or less per unit is possible, and the effect of the present invention is remarkable. However, problems such as increased retention time of water in the tank cause bacteria to propagate, and the generated suspended matter to adhere to the photosensitive material. Sign. As a solution to this problem, a method for reducing calcium and magnosium described in Japanese Patent Application Laid-open No. 62-288838 is proposed.
It can be used very effectively. Also, JP-A-57-
Isothiazolone compounds and thiahendazonos described in Publication No. 8542, chlorine-based disinfectants such as chlorinated sodium isosyphnurate described in Publication No. 61-120145, benzotriazole described in JP-A No. 6267761, Nichi-ion, etc. Hiroshi Horiguchi, “Chemistry of anti-bacterial and anti-mildew J” (1)

Further, in the washing water, a surfactant as a draining agent and a chelating agent typified by EDTA as a water softener can be used.

The above-mentioned water washing step can be followed or the stabilizing solution can be directly treated without going through the water washing step. A compound having an image stabilizing function is added to the stabilizing liquid.
Examples include buffers for preparing H and ammonium compounds. Further, in order to prevent the proliferation of bacteria in the liquid and to impart anti-mold properties to the photographic material after processing, the various disinfectants and anti-mold agents described above can be used.

Furthermore, surfactants, optical brighteners, and hardeners can also be added. In the processing of the photosensitive material of the present invention, when stabilization is performed directly without passing through a water washing step,
No. 8543, No. 58-14834, No. 6022034
All known methods described in Publication No. 5 and the like can be used.

In addition, it is also a preferred embodiment to use chelating agents such as 1-hydroxyethylidene-II diphosphonic acid and ethylenediaminetemethylenephosphonic acid, and magnesium and bismuth compounds.

A so-called rinsing liquid is also used as a washing liquid or stabilizing liquid used after the desilvering process.

The preferred pH of the water washing step or stabilization step is 4 to 10, more preferably 5 to 8. The temperature can be set in various ways depending on the use and characteristics of the photosensitive material, but generally it is between 20'C and 50'C.
°C5 preferably 25°C to 45°C.

Although the time can be set according to child care, a shorter time is preferable from the viewpoint of reducing processing time. Preferably it is 10 seconds to 60 seconds, more preferably 15 seconds to 45 seconds. The smaller the amount of replenishment, the better from the viewpoints of running costs, reduced emissions, ease of handling, and the like.

A specific preferred amount of replenishment is 0.5 to 50 times, preferably 3 to 40 times, the amount brought in from the previous bath per unit area of the photosensitive material. Or, it is 500 d or less, preferably 30 M or less per photosensitive material. Further, replenishment may be performed continuously or intermittently.

The liquid used in the water washing and/or stabilization step can also be used in the previous step. An example of this is reducing the amount of waste liquid by using a multi-stage counter-current system to flow the overflow of washing water into the bleach-fixing bath that is the previous bath, and replenishing the bleach-fixing bath with -a condensate. .

A stirring member 70, which is an important part of the present invention, is provided in the developer tank 12, bleach-fix tank 14, and washing tank 16. The stirring member 70 will be explained below.

FIG. 1 is a perspective view of the stirring member 70.

The stirring member 70 is provided, for example, between a pair of racks 72 that support the conveyance roller 24. A guide hole 74 extending horizontally is formed in the rack 72, and both ends 76 of the stirring member 70 enter into the guide hole 74, and both ends 76 move in the horizontal direction shown by arrow A within the guide hole 74. It is possible. The stirring member 70 is provided along the width direction of the photosensitive material 20 and has a pair of inclined surfaces 78 .

By reciprocating in the direction of arrow A, the processing liquid is smoothly guided by the fins 102 that are inclined with respect to the direction of movement, and the processing liquid is exchanged in the vicinity of the photosensitive material 20.

FIG. 8 is a plan view of another modification of the stirring member 70. The configuration of the stirring member 70 is the same as that shown in FIG.
The stirring member 70 has a crank bar 84 pivotally supported on one end of a shaft 100, which is movable within the same plane as the shaft 100. The stirring member 70 is driven in the horizontal direction indicated by arrow A by the drive configuration shown in FIG. That is, the stirring member 70 horizontally reciprocates along the width direction of the photosensitive material 20 to stir the processing liquid.
