Description

  The present invention relates to an automatic development processing apparatus used for processing a silver halide color photographic light-sensitive material and a processing using the same, and particularly when the replenishment amount is reduced, even in a low season or a small amount of processing, The present invention relates to an automatic development processing apparatus capable of obtaining good photographic performance and processing using the same.

  The silver halide color photographic light-sensitive material is characterized by high image quality, but in order to obtain it, the processing solution used must always maintain an appropriate composition. In recent years, interest in environmental conservation has increased remarkably, and the amount of processing liquid replenished has been reduced from the viewpoint of source reduction, which is the basis of environmental conservation. However, as the replenishment amount decreases, the retention time of the treatment liquid in the treatment tank increases, and during that time, evaporation of moisture from the treatment liquid concentrates the treatment liquid, resulting in a problem that impairs proper treatment performance. Yes. Evaporation of water in the treatment tank and accompanying liquid composition fluctuations are likely to occur during small-scale treatment periods such as the off-season (season off). Such evaporation of water can be corrected by performing an appropriate amount of water in principle, but it is not easy to estimate how much water has actually evaporated. In addition, the number of in-store development laboratories such as minilabs has increased in recent years due to the increasing dispersal of development laboratories, and along with this, development work has become automated, labor-saving, simplified, and the operation of estimating and correcting the evaporated moisture can be simple. Desired. Regarding simplification of moisture correction, Japanese Patent Application Laid-Open No. H10-228561 discloses a development processing apparatus and processing method that incorporates means for calculating the amount of evaporated water with high accuracy and performing appropriate automatic moisture correction.

  However, even if the evaporation moisture is corrected appropriately, the remaining problem is that it adheres to the rack exposed to the outside of the liquid from the immersion part of the processing tank, particularly to the cross-over rack extending between the connected processing tanks. This is because the processed liquid is dried and the processing liquid components are fixed to the rack member, and the photosensitive material conveyed through the developing device is stained or scratched.

The above-mentioned prior art relating to the invention of this application includes the following documents.
JP-A-7-159966

  The present invention has been made from the above background. Therefore, even if the object of the present invention is processing by a simple automatic processor such as an over-the-counter developer, contamination of the external conveyance path such as a crossover rack is caused. It is an object of the present invention to provide an automatic development processing apparatus for a silver halide color photographic material which is reduced and does not cause troubles such as scratches on the photosensitive material being processed, and a processing method using the same.

  In order to solve the above-mentioned object, the present inventor has a ventilation mechanism for circulating the air in the space of the processing liquid tank section and / or the drying section space in the automatic development processing apparatus and / or exhausting the air outside the apparatus. As a result, it was found that the evaporation of the liquid adhering to the external conveyance path such as a crossover rack can be suppressed while controlling the evaporation in the developing device to a low level under specific ventilation conditions. By realizing this condition, it was thought that the contamination outside the liquid could be improved while controlling the quality of the processing liquid in the processing tank, and further investigations were made to reach the present invention described below.

(1) Provided with a ventilation mechanism that circulates and / or exhausts the air in the space of the processing liquid tank and / or the drying unit space in the automatic development processing apparatus in the respective spaces, and the ventilation mechanism The ventilation duct is loaded with an air volume control member composed of a plurality of flow paths having a maximum cross-sectional area of 0.95 cm ² or less per location in the ventilation path; Silver halide photography characterized in that the air in the tank section space and / or the drying section space circulates in each space and / or passes through the air volume control member when exhausted outside the apparatus. Automatic development processing equipment for processing photosensitive materials.
(2) The automatic development processing apparatus for processing a silver halide photographic light-sensitive material as described in (1) above, wherein the flow path forming material of the ventilation mechanism is at least one selected from the following group (a).
(A) Group A compound or alloy containing titanium, zirconium, silicon, manganese, gold, aluminum, copper, silver or platinum as a constituent element, iron (II) compound, polyvinyl alcohol and inorganic carbon, and iron or aluminum.
(3) A method for processing a silver halide color photographic light-sensitive material, wherein the processing is performed using the automatic development processing apparatus according to the above (1) or (2).

The features of the automatic development processing apparatus for processing a silver halide color photographic light-sensitive material according to the present invention are as described above, in which the air in the processing solution tank section and / or the air in the drying section is circulated and / or apparatus in each space. An air volume control member composed of a plurality of flow paths having a maximum cross-sectional area of 0.95 cm ² or less is installed in a ventilation path of a ventilation duct of a ventilation mechanism that exhausts outside, and the treatment liquid tank This is the adoption of a flow path structure that passes through the air volume control member when the air in the partial space and / or the dry space circulates and / or exhausts outside the apparatus. This means that the exhaust strength outside the device does not become excessive while the strength is properly maintained. If the ventilation strength is simply lowered by reducing the ventilation strength, if the drying outside the liquid is reduced, serious quality deterioration such as mixing of the bleach-fixing solution into the color developing tank and occurrence of stain occurs, but the above-mentioned ventilation mechanism of the present invention. If this is the case, the ventilation strength is maintained, there is no such mixing, sticking of the processing liquid component to the outside of the liquid is suppressed, and the drying capacity is also maintained normally without excessive evaporation of the processing liquid tank. .
The space of the processing liquid tank portion refers to an air portion such as an upper space, a side space, or a bottom space in the processing liquid tank portion in which a series of processing liquid tank groups are arranged to perform the immersion liquid treatment. The upper space of the treatment liquid tank group is a main space region, but is not limited to the upper portion.

The automatic development processing apparatus for processing a silver halide photographic light-sensitive material according to the present invention has a maximum interruption per one place for circulating or exhausting the air in the space of the processing solution tank and / or the space of the drying section to the outside of the apparatus. It is characterized by comprising a ventilation duct loaded with an air volume control member composed of a plurality of flow paths having an area of 0.95 cm ² or less, and this ventilation mechanism causes fluctuations in the processing liquid composition in the treatment tank. In addition, the drying conditions are maintained normally, the contamination of the crossover rack is reduced, and the photosensitive material being processed does not cause a failure such as a scratch. Therefore, it is possible to maintain a stable finish quality even in a small storefront shop or in a low season such as winter.

Hereinafter, the present invention will be described in more detail.

This is an example of a flat membranous mesh having j), k) and l) which is configured to be ventilated outward from the concentric double cylindrical core side.

The air volume control member is loaded in a ventilation duct of a ventilation mechanism provided to circulate the air in the processing liquid tank section and the drying section space in the automatic development processing apparatus and exhaust the air in the respective spaces outside the apparatus. And a plurality of flow paths having a maximum cross-sectional area of 0.95 cm ² or less.
The structure and material of the air flow control member can be used as long as the intended effect is obtained, the required strength in the use environment is ensured, and it is stable against corrosive action.

  Color and black-and-white developers usually contain sulfites such as sodium sulfite, potassium sulfite, sodium bisulfite, potassium bisulfite, sodium metasulfite, potassium metasulfite and carbonyl sulfite adducts as preservatives. These contents are 5 g or less, 1 g or less (including no additives) for a color developer per liter of developer, and 0 g to 50 g for a black and white developer.

The color developer contains various hydroxylamines as preservatives. Hydroxylamines may be substituted or unsubstituted. Examples of the substituent include those in which the nitrogen atom of hydroxyalumines is substituted by a lower alkyl group, particularly N, N-dialkyl-substituted hydroxylamines substituted by two alkyl groups (for example, 1 to 3 carbon atoms). It is done. A combination of N, N-dialkyl-substituted hydroxylamine and alkanolamine such as triethanolamine is also used. The content of hydroxylamines is 0 to 5 g per liter of developer.

  Color and black-and-white developers have a pH of 9-12. Various buffering agents are used to maintain the pH. Examples of the buffer include carbonate, phosphate, borate, tetraborate, hydroxybenzoate, glycine salt, N, N-dimethylglycine salt, leucine salt, norleucine salt, guanine salt, 3,4- Dihydroxyphenylalanine salt, alanine salt, aminobutyrate, 2-amino-2-methyl-1,3-propanediol salt, valine salt, proline salt, trishydroxyaminomethane salt, lysine salt and the like can be used. In particular, carbonate, phosphate, tetraborate, and hydroxybenzoate are excellent in solubility and buffering ability in a high pH range of pH 9.0 or higher, and adversely affect photographic performance even when added to a developer. There is an advantage that there is no (fogging etc.) and it is inexpensive, and these buffering agents are often used. The amount of the buffer added to the developer is usually 0.1 mol to 1 mol per liter of the developer.

  In addition, various chelating agents are added to the developer as an anti-precipitation agent for calcium and magnesium or to improve the stability of the developer. Representative examples thereof include nitrilotriacetic acid, diethylenetriaminepentaacetic acid, nitrilo-N, N, N-trimethylenemethylene phosphonic acid, ethylenediamine-N, N, N ′, N′-tetramethylenephosphonic acid, 1,3-diamino-2 -Propanoltetraacetic acid, transcyclohexanediaminetetraacetic acid, 1,3-diaminopropanetetraacetic acid, 2-phosphonobutane-1,2,4-tricarboxylic acid, 1-hydroxyethylidene-1,1-diphosphonic acid .

Compounds, thione compounds, imidazoles and the like.

  Many color paper color developers contain alkylene glycols and benzyl alcohols together with the above color developing agents, sulfites, hydroxylamine salts, carbonates, hard water softeners and the like. On the other hand, color negative developers, color positive developers, and some color paper developers do not contain these alcohols.

  In addition, bromine ions are often contained in the developer for the purpose of fog prevention, but it is common to use a replenisher that does not contain bromine ions for photosensitive materials mainly composed of silver chloride. is there. In addition, compounds that give chlorine ions such as NaCl and KCl may be contained as an inorganic antifoggant. Moreover, it often contains various organic antifoggants. Examples of the organic antifoggant may include adenines, benzimidazoles, benztriazoles, and tetrazoles. The content of these antifoggants is 0.010 g to 2 g per liter of the developer. These antifoggants include those that elute from the photosensitive material during processing and accumulate in the developer. In particular, the present invention can be effectively treated even in a waste liquid in which the total halogen ion concentration such as bromine ion and chlorine ion is 1 mmol or more per liter of the mixed liquid as described above. This is particularly effective when the bromine ion concentration is 1 mmol or more per liter of the mixed solution.

  Further, the developer contains various surfactants such as alkylphosphonic acid, arylphosphonic acid, fatty acid carboxylic acid, and aromatic carboxylic acid.

These ferric ion complex salts may be used in the form of complex salts or ferric salts such as ferric sulfate, ferric chloride, ferric nitrate, ferric ammonium sulfate, ferric phosphate. And a chelating agent such as aminopolycarboxylic acid may be used to form a ferric ion complex salt in a solution. Moreover, you may use a chelating agent in excess rather than forming a ferric ion complex salt. Of the iron complexes, aminopolycarboxylic acid iron complexes are preferred.

  The amount of the bleaching agent added is such that the concentration of the prepared treatment liquid is 0.01 to 1.0 mol / liter, preferably 0.03 to 0.80 mol / liter, more preferably 0.05 to 0.70 mol / liter.

When the pH is lower than this, the desilvering property is improved, but the deterioration of the solution and the leuco conversion of the cyan dye are promoted. On the contrary, if the pH is higher than this, desilvering is delayed and stain is likely to occur. The pH range of the bleaching solution made from the granule of the present invention is 8 or less, preferably 2 to 7, and particularly preferably 2 to 6. If the pH is lower than this, the deterioration of the liquid and the leuco conversion of the cyan dye are promoted. Conversely, if the pH is higher than this, desilvering is delayed and stain is likely to occur. In order to adjust the pH, the solid acid described above and the solid alkali potassium hydroxide, sodium hydroxide, lithium hydroxide, lithium carbonate, sodium carbonate, potassium carbonate and acidic or alkaline as necessary are used. Buffering agents and the like can be added.

  As a preservative, ascorbic acid, a carbonyl bisulfite adduct, a carbonyl compound, or the like may be added in addition to the above.

  After completion of the fixing process, an alternative stabilizing bath for washing with water and a stabilizing bath for stabilizing images are performed. As the stabilizing bath treatment agent, the method of reducing calcium and magnesium described in JP-A-62-288838 can be used very effectively. Further, chlorinated fungicides such as isothiazolone compounds and siabendazoles described in JP-A-57-8542, chlorinated sodium isocyanurate described in JP-A-61-120145, JP-A-61-267761 Benzotriazole, copper ion, and other publications described in the gazette, Hiroshi Horiguchi, “Chemistry of Antibacterial and Antifungal” (1986) Sankyo Publishing, Hygiene Technology Association, “Microbial Decontamination, Sterilization, Antifungal Technology” (1982) The bactericides described in the “Industrial Antibacterial and Antifungal Encyclopedia” (1986) edited by the Industrial Technology Association of Japan and the Japanese Society for Antibacterial and Antifungal Society may also be used.

Furthermore, a surfactant can be used as a draining agent, and a chelating agent represented by EDTA can be used as a water softening agent.
[Applicable photosensitive material]

  Next, the photosensitive material used in the present invention will be described. The photosensitive material used in the present invention is a color photographic photosensitive material for photographing such as a color negative film and a color photographic material for printing such as color photographic paper, which are widely used in the photographic market as described above in relation to the object and background of the invention. In this photosensitive material, at least one photosensitive layer is provided on a support. A typical example is a silver halide photographic light-sensitive material having at least one photosensitive layer comprising a plurality of silver halide emulsion layers having substantially the same color sensitivity but different sensitivity on a support. It is.

  In a multilayer silver halide color photographic light-sensitive material for photographing, the photosensitive layer is a unit photosensitive layer having a color sensitivity to any one of blue light, green light, and red light, and is generally an array of unit photosensitive layers. However, the red color-sensitive layer, the green color-sensitive layer, and the blue color-sensitive layer are installed in this order from the support side. However, depending on the purpose, the installation order may be reversed, or the installation order may be such that different photosensitive layers are sandwiched in the same color-sensitive layer. A non-photosensitive layer may be provided between the above-described silver halide photosensitive layers and as the uppermost layer and the lowermost layer. These may contain couplers, DIR compounds, color mixing inhibitors and the like described later. A plurality of silver halide emulsion layers constituting each unit photosensitive layer are sequentially exposed to a support, two layers of a high-sensitivity emulsion layer and a low-sensitivity emulsion layer as described in DE 1,121,470 or GB 923,045. It is preferable to arrange so that the degree is low. Further, as described in JP-A-57-112751, 62-200350, 62-206541, 62-206543, a low-sensitivity emulsion layer on the side away from the support, close to the support A high-sensitivity emulsion layer may be provided on the side.

  In addition, as described in JP-B-49-15495, the upper layer is a silver halide emulsion layer having the highest sensitivity, the middle layer is a silver halide emulsion layer having a lower sensitivity, and the lower layer is more sensitive than the middle layer. Examples include an arrangement composed of three layers having different sensitivities in which a low silver halide emulsion layer is arranged and the sensitivities are gradually lowered toward the support. Even in the case of being composed of three layers having different sensitivities, as described in JP-A-59-202464, the medium-sensitive emulsion layer / high They may be arranged in the order of sensitive emulsion layer / low sensitive emulsion layer. In addition, they may be arranged in the order of high sensitivity emulsion layer / low sensitivity emulsion layer / medium sensitivity emulsion layer, or low sensitivity emulsion layer / medium sensitivity emulsion layer / high sensitivity emulsion layer. Further, the arrangement may be changed as described above even when there are four or more layers.

  In order to improve color reproducibility, the main photosensitive layers such as BL, GL, and RL and spectral sensitivity distribution described in the specifications of US 4,663,271, 4,705,744, 4,707,436, and JP-A-62-160448 and 63-89850 are disclosed. It is preferable to dispose a donor layer (CL) having different multi-layer effects adjacent to or close to the main photosensitive layer.

  A photosensitive material for printing generally uses a reflective support, and is often installed in the order of a red color-sensitive layer, a green color-sensitive layer, and a blue color sensitivity in order from the side far from the support. As the silver halide emulsion, a cubic emulsion of silver chloride or silver chlorobromide grains of high silver chloride is used.

The silver halide photographic emulsion that can be used in the present invention is, for example, Research Disclosure (hereinafter abbreviated as RD) No. 17643 (December 1978), pp. 22-23, "I. Emulsion preparation and types" No. 18716 (November 1979), 648, No. 307105 (November 1989), pages 863 to 865, and “Physics and Chemistry of Photography”, published by Paul Monter (P.

Also preferred are monodisperse emulsions described in US 3,574,628, 3,655,394 and GB 1,413,748.
Photographic additives that can be used in color light-sensitive materials are also described in the RD, and the description locations related to the following table are shown.

  Next, as a printer for producing a print from a developed film using a color print material, a general-purpose printer is used. In addition to being used in a printing system using a normal negative printer, a cathode ray (CRT) It is also suitable for a scanning exposure method using The cathode ray tube exposure apparatus is more convenient and compact than an apparatus using a laser, and is low in cost. Also, the adjustment of the optical axis and color is easy. As the cathode ray tube used for image exposure, various light emitters that emit light in the spectral region are used as necessary. For example, any one of red light emitters, green light emitters, and blue light emitters, or a mixture of two or more thereof may be used. The spectral region is not limited to the above red, green, and blue, and a phosphor that emits light in the yellow, orange, purple, or infrared region is also used. In particular, a cathode ray tube that emits white light by mixing these light emitters is often used.

  When the photosensitive material has a plurality of photosensitive layers having different spectral sensitivity distributions, and the cathode ray tube also has a phosphor that emits light in a plurality of spectral regions, a plurality of colors are exposed at a time, i.e., a plurality of cathode ray tubes Color image signals may be input to emit light from the tube surface. A method of sequentially inputting image signals for each color, causing each color to emit light sequentially, and exposing through a film that cuts colors other than that color (surface sequential exposure) may be adopted. However, since a high-resolution cathode ray tube can be used, it is preferable for improving image quality.

  The photosensitive material of the present invention is a monochromatic high light source such as a gas laser, light emitting diode, semiconductor laser, semiconductor laser, or second harmonic generation light source (SHG) that combines a solid-state laser using a semiconductor laser as an excitation light source and a nonlinear optical crystal. It is preferably used in a digital scanning exposure method using density light. In order to make the system compact and inexpensive, it is preferable to use a second harmonic generation light source (SHG) that combines a semiconductor laser, a semiconductor laser, or a solid-state laser and a nonlinear optical crystal. In particular, in order to design a compact, inexpensive, long-life and high-stability device, it is preferable to use a semiconductor laser, and at least one of the exposure light sources is preferably a semiconductor laser.

When such a scanning exposure light source is used, the spectral sensitivity maximum wavelength of the photosensitive material of the present invention can be arbitrarily set according to the wavelength of the scanning exposure light source to be used. In a solid laser using a semiconductor laser as an excitation light source or an SHG light source obtained by combining a semiconductor laser and a nonlinear optical crystal, the oscillation wavelength of the laser can be halved, so that blue light and green light can be obtained. Therefore, the spectral sensitivity maximum of the photosensitive material can be given to the usual three wavelength regions of blue, green, and red. When the exposure time in such scanning exposure is defined as the time for exposing the pixel size when the pixel density is 400 dpi, the preferable exposure time is 10 ⁻⁴ seconds or less, more preferably 10 ⁻⁶ seconds or less. For the purpose of preventing unauthorized copying of the photosensitive material subjected to the processing according to the present invention, a latent image of a microdot pattern can be given to the photosensitive material. This method is described in JP-A-9-226227.

  Preferred scanning exposure methods applicable to the present invention are described in detail in the patents listed in the table above. For processing the light-sensitive material of the present invention, page 26, lower right column, line 1 to page 34, upper right column, line 9 of JP-A-2-207250, and page 5, JP-A-4-97355. The processing materials and processing methods described in the upper left column, line 17 to page 18, lower right column, line 20 are preferably applicable.

EXAMPLES Hereinafter, although an Example demonstrates this invention more concretely, these do not limit the scope of the present invention at all.
[Example 1]
(Preparation of concentrated fixing composition)
A concentrated fixing composition was prepared according to the following formulation.
(Concentrated fixing composition formulation)

Ammonium thiosulfate (750 g / L) 880 ml
70 g of ammonium bisulfite aqueous solution (65 mass%)
10g ethylenediaminetetraacetic acid
1L with water
pH (adjusted with ammonia water) 7.0
(Treatment agent container)

The treatment agent container used in this example is a plurality of sample containers whose thickness of the vessel wall is changed as follows, both of which are hollow blow-molded, both of which have an inner method of about 75 mm and a prismatic column height of 250 mm. It has a prismatic shape and is sealed with a cap that has a spiral on the neck and a female spiral that fits into the neck. Both the container body and the cap are made of high-density polyethylene (HDPE), and the cap is low-density polyethylene (LDPE). The thickness of the thinnest part (because of blow molding, the thin part is a prismatic side wall part) is 0. .5 mm. Further, since this container is mounted on an automatic processor and automatically opened to allow the concentrated composition to be charged into the replenishing tank, the cap is also provided with a thin portion through which the opening nozzle can penetrate. The thickness of this thin part is also 0.5 mm.
Each concentrated fixing composition obtained above was diluted 1.13 times with water to obtain a fixing replenisher. Other processing solutions were developed (running process) continuously using the following composition.

(Photosensitive material for testing)
The photosensitive material used for the test is “Venus 400 135 size 27 sheets (manufacturing number: X02121)” manufactured by Fuji Photo Film Co., Ltd.
(Automatic developing machine and developing method used in the test)

Development processing was performed according to the following color negative developing machine and processing specifications.
As the processing machine, an experimental machine in which the processing time of an automatic processor FP-363SC manufactured by Fuji Photo Film Co., Ltd. was modified was used. This machine has the configuration shown in FIG. 1 and is provided with ventilation control members (members 62 and 63 in the treatment liquid tank space and 72 in the drying section) shown by hatching in FIG. As described above with respect to the description, the circulating air is blown (partially discharged) while controlling the air volume.
The size of the members (62, 63, 72) was 25 cm ^{2 in} the direction perpendicular to the flow path. As the flow rate of the flow path per flow path, a value obtained by dividing the flow rate of the member outlet by the number of flow paths of the member was used. As a result, in the members 62 and 63, per passage, in 500 cm ³ / min member 72 was set to 50000 cm ³ / min per passage.
Although this machine is not shown in FIG. 1, it has an automatic opening / automatic replenishment replenishment system. The outline of the machine is the plastic (HDPE) bottle described in the main body of the specification. Place the bottles side by side, cover the blending unit, and move the bottle downward from the top so that the tip of the nozzle is inserted into the squeeze nozzle for opening that is equipped with the nozzle tip upward. The lid is pierced and the composition solution inside is poured into the replenishing tank. Thereafter, a fixed amount of washing water is jetted from the nozzle hole of the squeezing nozzle to wash the inside of the bottle, and the washing water also flows down to the replenishing tank and is used as dilution water for preparing the replenisher. . Therefore, the preparation processing agent filled in the bottle is diluted with washing water or the like to automatically prepare the replenisher.
