Processing method of silver halide photographic light sensitive material

Abstract: A method for continuously processing an exposed silver halide photographic light sensitive material comprises the steps of: developing said material with a developing solution, the developing solution being replenished with a first water and a solid developing composition containing a developing agent and a first sulfite according to a processing amount of said material; and fixing the developed material with a fixing solution, the fixing solution being replenished with a second water and a solid fixing composition containing a fixing agent and a second sulfite according to a processing amount of said material, and no other processing being carried out between said developing and said fixing, wherein the second sulfite is replenished in an amount of 0 to 0.05 mol per liter of the second water.

Description: The invention relates to a processing method for a silver halide photographic light sensitive material and particularly to a processing method for a silver halide photographic light sensitive material without deteriorating fixability and drying property even when the processing is continuously carried out at a high speed. Currently, many photographic processing compositions are sold as concentrated solutions which are diluted at usage. However, the concentrated solutions are heavy and bulky, and improvements in transport cost, storage space and operative efficiency has been strongly demanded. In order to solve this problem, a solid processing composition has been proposed. The solid processing composition is preferable in view of reduction of containers and an environmental improvement. However, the solid processing composition has a problem in that it takes a long time to dissolve. That is, when the solid processing composition and water are replenished in a processing tank, the solid component is slow in dissolving and remains insoluble, resulting in deterioration of the processing properties. Particularly, rapid processing is recently predominant, and development time is 30 seconds or less or a large amount of light sensitive materials such as 100m 2 /hour are processed. Such a rapid and continuous processing causes marked dissolving retardation, resulting in deterioration of processing properties. EP-A-0704756 which forms part of the state of the art under Article 54(3) EPC, discloses a photographic processing method which comprises developing and fixing the exposed photographic light-sensitive material. At least one of the developing and fixing solutions may be replenished with a solid composition. The solid composition may comprise a sulfite. When sulfite is contained in the developer replenisher, it is in an amount of less than 0.45 mol/l. The deterioration of processing properties due to the above dissolving retardation includes sensitivity deviation in development of deterioration of fixability or drying in fixing. In order to solve this problem, a method has been proposed in which the form of the solid composition is improved or a solid composition crushing means is provided on an automatic processor, but the method is not sufficient to solve the problem. Accordingly, an object of the invention is to provide a method for processing a silver halide photographic light-sensitive material without deteriorating developability (such as sensitivity variation), fixability and drying property even when the processing is continuously carried out at a high speed. Fig.1 is a plane view showing one example of the processor used in the method of the invention. The above objects of the invention have been attained by the following: (1) A method for processing a silver halide photographic light-sensitive material, using a processor having a developing tank charged with developer containing a developing agent and a sulfite and having a fixing tank charged with a fixer containing a fixing agent and 0.05 mol/liter or less of a sulfite, no other processing tank being provided between the developing tank and the fixing tank, the method comprising continuously processing the material, wherein the developer is replenished with water and a solid developing composition containing a developing agent and a sulfite, and the fixer is replenished with water and a solid fixing composition containing a fixing agent. (2) The method of item (1), wherein the fixer is replenished with water in an amount of 300 ml/m 2 or less of light sensitive material having been processed. (3) The method of item (1) or (2), wherein the sulfite content of the developer is 0.3 mol/liter or more. (4) The method of item (1), (2) or (3), wherein the solid developing composition satisfies the following inequality: [(M Na ) / (M K )] > 1 wherein M Na represents a mol number of sodium sulfite contained in 1 g of the solid developing composition; and M K represents a mol number of potassium sulfite contained in 1 g of the solid developing composition. (5) A method for processing an exposed silver halide photographic light-sensitive material with a processing solution contacting a solution containing an electrolyte, the processing solution being directly replenished with a solid processing composition for a silver halide photographic light-sensitive material, wherein the method comprises electrolysing at least through an anion exchange membrane, the processing solution. (6) The method of item (1), (2), (3) or (4), wherein the method comprises processing an exposed silver halide photographic light-sensitive material with a processing solution contacting a solution containing an electrolyte, the processing solution being directly replenished with a solid processing composition for a silver halide photographic light-sensitive material, wherein the method comprises electrolysing at least through an anion exchange membrane, the processing solution. (7) The method of item (5) or (6), wherein the replenishing amount of water for dissolving the solid processing composition is 300 cc/m 2 or less of light sensitive material having been processed. (8) The method of item (5), (6) or (7), wherein the processing amount of the silver halide photographic light sensitive material is 20 m 2 per hour or more. The objects of the invention could be attained by a method of increasing the dissolving speed by reducing the sulfite content of a solid fixing composition, a method of recovering a deteriorated fixability by specifying a ratio of a sodium ion concentration to a potassium ion concentration in a developer, or a method of increasing the dissolving speed by removing undesired salts from processing solutions. The fixer contains a sulfite (a sulfite component) as a preserver of a thiosulfate. The sulfite content is preferably less, since the sulfite component is slow in dissolving and has a greatly adverse effect on the dissolving speed of a solid processing composition. On the other hand, the developer also contains a sulfite (a sulfite component) as a preserver of the developer, and the developer overflows to the fixer carried by the processed material on processing. Accordingly, since the sulfite is supplied to the fixer from the developer on processing, the replenishing amount of the sulfite to the fixer may be less. Especially when the replenishing amount of fixer replenisher is less, the ratio of the overflowed developer to the fixer is higher and the replenishing amount of the sulfite to the fixer is less. The conventional solution kit is likely to be subjected to oxidation decomposition in the form of concentrated kit or diluted solution for use, and requires the sulfite component to prevent oxidation. The solid fixing composition markedly reduces decomposition of a thiosulfate, the addition of the sulfite for preventing the decomposition is not necessary and the sulfite component content can be decreased in the solid fixing kit. Another method of improving solubility includes one removing a salt through an anion exchange membrane. When developing is carried out, a sodium or potassium halide occurs and causes an increase of a salt strength. The salt strength increases in a fixer since developer overflows to the fixer together with dissolution of silver halide. In view of the above, the solubilizing speed of the solid processing composition could be increased by removing the undesired ion. According to this method, processability could be improved. In development, fluctuation such as sensitivity lowering has been restrained, and in fixing, deterioration of fixibility due to a solubility retardation of a fixing agent or drying deterioration due to a solubility retardation of an aluminium component has been prevented. The fixability deterioration due to a solubility retardation of a solid processing composition could be improved by specifying the ratio of potassium ion to sodium ion of a sulfite in the developer. The sodium ion is preferable since a potassium ion in the developer overflows to the fixer, resulting in the fixer deterioration. A method using a sodium ion was not preferable in liquid form since the kid volume of a concentrated developer increased in view of solubility of the sodium salt. However, in the solid form the volume was not increased and the fixing property was improved even if the sodium salt is used instead of the potassium salt of a sulfite. The object of the invention has been attained by the above mentioned. The invention will be detailed below. The solid processing composition used in the method of the invention is in the form of a powder as described above or as tablets, pellets or granules, and is optionally subjected to anti-humidity treatment. The powder referred to herein is an aggregate of fine crystals. The granules referred to herein are obtained by granulating the powder, and the granules have a particle diameter of from 50 to 5000 µm aggregates of fine crystals. The tablets referred to herein are obtained by compression-molding powder or granules into a definite form. In order to prevent variation of photographic properties, it is effective to reduce an aperture value of a developer tank in an automatic processor. The aperture value is preferably 80 cm 2 /liter or less. When the aperture value exceeds 80 cm 2 /liter, insoluble solid processing agents or concentrated solutions immediately after dissolving the solid agents are likely to be subjected to air oxidation and produce insoluble matters and scums, resulting in problems of staining in the processor or light sensitive materials processed. These problems can be solved in the case of a 80 cm 2 /liter or less aperture value. The aperture value referred to herein is an area per unit volume at which a processing solution contacts atmospheric air. The unit volume is in terms of cm 2 /liter. The aperture value of the invention is preferably 80 cm 2 /liter or less, more preferably 50 to 3 cm 2 /liter, and still more preferably 35 to 10 cm 2 /liter. The aperture value can be reduced generally by using a floating cover for shielding air which is made of a resin or by using a slit type processing tank disclosed in Japanese Patent O.P.I. Publication Nos. 63-131138/1988, 63-216050/1988 and 63-235940/1988. In an automatic processor which may be used to perform the method of the invention, the processing solution is preferably circulated continuously by driving the pump for a specific time necessary to dissolve the solid processing composition, even after the processing of light sensitive materials is completed and the transporting of the materials is stopped. The time of driving the pump from the completion of processing is preferably 2 hours or less, more preferably from 10 to 70 minutes, and still more from preferably 15 to 50 minutes. Longer processing is not preferable in view of operability, energy saving, deterioration of the processing solution or clog of the filter. On the contrary, the dissolution of the solid composition is not sufficient if the time is too short. In order to solidify the photographic processing composition, any method can be used in which a concentrated solution or a mixture of fine-powdered or granuled processing agents with a water soluble binder is kneaded and molded, or a pre-molded processing agent is coated with a covering layer by spraying a water soluble binder. (See JP Application Nos. 2-135887/1990, 2-203165/1990, 2-203166/1990, 2-203167/1990, and 2-300405/1990.) The preferable method for preparing tablets is a method in which a powdered processing composition is granulated and the resulting granules are tableted to obtain tablets. The tablets prepared by this method have advantages that solubility and storage stability are improved and stable photographic properties are obtained as compared with those prepared by the method that the solid processing composition is only mixed and then tableted. As for the granulating processes for forming tablets, it is possible to use any of the well-known processes such as the processes of a rolling granulation, an extrusion granulation, a compression granulation, a cracking granulation, a stirring granulation, a fluidized-layer granulation and a spray-dry granulation. When the granules are mixed and compressed to obtain tablets, the average particle size of the granules is to be within the range of preferably from 100 to 800 µm and more preferably from 200 to 700 µm in that localization of components or so-called segregation occurs with difficulty. As to particle size distribution, not less than 60% of the granules have a deviation of preferably ±200 to 250 µm. The granules are used as they are. When the granules are compressed, well known compressors such as a hydraulic press machine, a single tableting machine, a rotary tableting machine and a bricketing machine can be used. The resulting solid processing composition may be in any form, and preferably in cylindrical form in view of productivity, handling or loose powder occurred in use. It is preferable that each component, for example, an alkali agent, a reducing agent, a bleaching agent, or a preservative, is separately granulated. As a result, the above effects become more remarkable. A tablet type processing composition can be prepared in any well known process or the method detailed in JP OPI Publication Nos. 51-61837/1976, 54-155038/1979 and 52-88025/1977 and British Patent No. 1,213,808. Also, the preparation of the granulated processing composition is detailed in JP OPI Publication Nos. 2-109042/1990, 2-109043/1990, 3-39735/1991 and 3-39739/1991. Further, a powder type processing composition can be prepared in any well known process as detailed in JP OPI Publication No. 54-133332/1979, British Patent Nos. 725,892 and 729,862 and German Patent No. 3,733,861. From the viewpoint of solubility and the desired effect of the present invention, the bulk density of the solid photographic processing composition described above is preferably 1.0 to 2.5 g/cm 3 ; this range is preferable from the viewpoint of solid strength for the lower limit and solid solubility for the upper limit. When the solid processing composition is of granule or powder form, the bulk density is preferably 0.40 to 0.95 g/cm 3 . Although the solid processing composition for the present invention may be used for various photographic processing agents such as developer, a fixer and a rinsing agent, the effect of the invention, particularly the photographic performance stabilizing effect, is enhanced when it is applied to the developer. Although solidification of part of a processing composition is included in the scope of the present invention, it is preferable to solidify the entire components of the processing composition. Desirably, each component is formed as a separate solid processing agent and packaged in the same package. It is also desirable to package each component in the order of repeated addition. It is preferable to add all processing agents to be supplied to respective processing tanks according to information on the amount of processing in the form of a solid. Where necessary, replenishing water is supplied on the basis of such information or other replenishing water controlling information. In this case, the liquid added to the processing tanks may be replenishing water alone. In other words, when two or more processing tanks require replenishment, by sharing the replenishing water, one tank alone is sufficient to store the replenishing liquid, resulting in an automatic processor size reduction. The replenishing water tank may be installed outside or inside the automatic processor machine. It is preferable in view of space saving that the replenishing water tank be installed inside the automatic processor. In solidifying a developing composition, it is preferable to solidify all of an alkali agent and reducing agent, and to confine the number of tablet kinds to not more than 3, preferably 1. When solidifying in two or more agents, it is preferable to package these tablets or granules in the same package. The solid processing composition used in the method of the invention can be packaged with the following materials: A moisture-resistive packaging material for the solid processing composition for use in the method of the invention can be embodied by making use of the following materials. As for a synthetic resin material, any material can be used upon selecting them from the group consisting of polyethylene (prepared in either a high-pressure method or a low-pressure method), polypropylene (prepared in either a non-stretching method or a stretching method), polyvinyl chloride, polyvinyl acetate, Nylon (either stretched or non-stretched), polyvinylidene chloride, polystyrene, polycarbonate, Vinylon, Eval, polyethylene terephthalate (PET), other polyesters, rubber hydrochloride, acrylonitrile-butadiene copolymer and an epoxy-phosphoric acid type resin (that is a polymer described in JP OPI Publication Nos. 63-63037/1988 and 57-32952/1982). Besides the above, a pulp may also be used. The material is preferably made of a single material, but, as film is used one which a synthetic resin film is laminated or coated or one of single layer. It is more preferable to use various gas-barrier layers. For example, either an aluminium foil or an aluminium-vacuum-evaporated synthetic resin is interposed between the above-mentioned two synthetic resin films. The total oxygen transmittance of the packaging material is not higher than 50 ml/m 2 24hr/atm (at 20°C and 65%RH) and, preferably, not higher than 30 ml/m 2 24hrs/atm in view of storage stability or prevention of staining occurrence. The total layer thickness of the laminated layer or single layer is 1 to 3000 µm, preferably 10 to 2000 µm and, more preferably 50 to 1000 µm. The above-mentioned synthetic resin film may consist of either a single (macromolecular) resin film or a film in which two or more resins are laminated. The single macromolecular resin film satisfying the requirements for the invention includes, for example, (1) polyethylene terephthalate (PET) having a thickness of not thinner than 0.1 mm; (2) an acrylonitrile-butadiene copolymer having a thickness of not thinner than 0.3 mm; and (3) a hydrochloric rubber having a thickness of not thinner than 0.1 mm. Among the above, polyethylene terephthalate can suitably be applied to the invention, because it is excellent in alkali resistance and acid resistance, too.Next, a laminated macromolecular resin film satisfying the requirements for the invention includes, for example, (4) PET / polyvinyl alcohol-ethylene copolymer (Eval) / polyethylene (PE); (5) stretched polypropylene (OPP) / Eval / PE; (6) unstretched polyproylene (CPP) / Eval / PE; (7) Nylon (N) / Aluminium foil (Al) / PE; (8) PET /Al / PE; (9) Cellophane / PE / Al / PE; (10) Al / paper / PE; (11) PET / PE / Al / PE; (12) N / PE / Al / PE; (13) paper / PE / Al / PE; (14) PET / Al / PET / polypropylene (PP); (15) PET / Al / PET / high-density polyethylene (HDPE); (16) PET / Al / PE / low-density polyethylene (LDPE); (17) Eval / PP; (18) PET / Al / PP; (19) paper / Al / PE; (20) PE / PVDC-coated Nylon / PE / ethylvinyl acetate-polyethylene condensate (EVA); (21) PE / PVDC-coated N / PE; (22) EVA / PE / Aluminium-evaporated Nylon / PE / EVA; (23) aluminium-evaporated Nylon / N / PE / EVA; (24) OPP / PVDC-coated N / PE; (25) PE / PVDC-coated N / PE; (26) OPP / Eval / LDPE; (27) OPP / Eval / CPP; (28) PET / Eval / LDPE; (29) ON (stretched Nylon / Eval / LDPE; and (30) CN (unstretched Nylon) / Eval / LDPE. Among them, the above-given (20) through (30) may preferably be used. Further, the foregoing packaging material is typically constituted of the following component arrangements in the order from the inside thereof, provided when the side attached to a processing composition is regarded as the inside. PE / paper sheet as a principal member / PE / Al / an epoxy-phosphoric acid type resin layer / a polyester type resin layer / PE; PE / K-Nylon / PE or an adhesive / Al / PE / paper sheet / PE; PE / Vinylon / PE or an adhesive / Al/ PE / paper sheet / PE; PE / vinylidene chloride / PE or an adhesive / Al / PE / paper sheet / PE; PE / polyester / PE or an adhesive / Al / PE / Paper sheet / PE; and Polypropylene / K-Nylon / polypropylene / Al / polypropylene / paper sheet / polypropylene. A mode of moisture-resistibly packaging powder, tablet or granule includes, for example, 4-side sealing; 3-side sealing; Stick-sealing (such as a pillow type or gusset type packaging); PTP sealing; and Cartridge sealing. Four-side sealing mode, 3-side sealing mode and stick-sealing mode (such as a pillow or cassette type sealing mode) are different in shape from each other and the above-given materials may be used therein, provided, when these modes are used in a peel-open system, a sealant is laminated so as to provided them with a peel-open aptitude. As for the above-mentioned peel-open system, there are, ordinarily, a cohesion-rupture system, an interface peeling system and a interlayer peeling system. To be more concrete, the cohesion-rupture system is a system in which an adhesive so-called a hot-melt and a heat-seal lacquer are both used as a sealer. When opening a package, the inside of a sealant layer is cohesion-ruptured and thereby the package is peel-opened. The interface peeling system is a system for peeling on the interface between films, in which a sealing film (that is a sealant) and an adherend are not completely fused together and, therefore, they can be peeled apart by applying an appropriate force. The sealant is a film prepared by mixing plural tacky resins, and it may be selected from polyethylene, polypropylene and a copolymer thereof, a polyester and so forth, so as to meet a material of the adherend. The foregoing interlayer peeling system is a system in which a multilayered extrusion film such as a laminated film is used as a sealant and peeling is then made on the interface between the laminated layers of the film. Among the peel-open systems applied with a film of the invention, an interlayer peeling system and an interface peeling system are preferable. Because such a sealant as mentioned above is thin, it is usual to use it upon laminating it on any one of the other films including, for example, those made of polyethylene, polypropylene, polystyrene, polycarbonate, polyester (such as polyethylene terephthalate), polyvinyl chloride, Nylon, Ever, or aluminium. However, taking a moisture resistance, an environmental aptitude and a compatibility with a content into consideration, polyethylene, polypropylene, polyester and ever may preferably be used. Also, taking a printability into consideration, the outermost surface is preferable to be comprised of, for example, a unstretched polypropylene polyester and paper sheet. A sealant includes, for example, CMPS film manufactured by Tocello Co., Difran PP-100 and PS-300 each manufactured by Dai-Nippon Ink Chemical Co., LTS film manufactured by Toppan Printing Co. and San-Seal FR and MS each manufactured by Sanei Chemical Co. A type thereof which already laminated with a polyester include, for example, Dikran C-1600T and C-1602T. PTP has a packaging mode in which a solid type processing composition is put in a PVC- or CPP-made sheet-shaped package that is a blister type package and then the package is heat-sealed by making use of an aluminium sealing material. From the viewpoint of preserving the environment to be safe, A-PET and a high moisture resistive PP (such as TAS-1130, TAS-2230 and TAS-3230 each manufactured by Taisei Chemical Industrial Co.) have recently been preferably used, while there has been a tendency to ban the use of PVC as a packaging material. When packaging, binding or covering a processing composition by making use of a water-soluble film or a binder, a water-soluble film or binder preferably applicable thereto include, for example, those comprising the following basic materials, namely, those of polyvinyl alcohol, methyl cellulose, polyethylene oxide, starch, polyvinyl pyrrolidone, hydroxypropyl cellulose, pullulan, dextran, gum arabic, polyvinyl acetate, hydroxyethyl cellulose, carboxyethyl cellulose, sodium carboxymethyl hydroxy ethyl cellulose, poly(alkyl)oxazoline and polyethylene glycol. Among them, those of the polyvinyl alcohol type and pullulan type are preferably used, from the viewpoint of a covering or binding effect. Polyvinyl alcohol is an especially suitable film-forming material and is also excellent in strength and softness under almost all conditions. A polyvinyl alcohol composition available on the market for casting into a film has a variety of molecular weight ranges and hydrolyzing degrees, however, it is preferable to have a molecular weight within the range of from 10000 to 100000. A hydrolyzing degree herein means a ratio of an acetic acid ester group of polyvinyl alcohol to be substituted by an hydroxyl group. In the case of a film, the degrees of a hydrolysis is usually within the range of from 70% to 100%. As mentioned above, the term, "polyvinyl alcohol", usually includes a polyvinyl acetate compound. The above-mentioned water-soluble film is prepared in such a common preparation process as described in, for example, JP OPI Publication Nos. 2-124945/1990, 61-97348/1986, 60-158245/1985, 2-86638/1990, 57-117867/1982, 2-75650/1990, 59-226018/1984, 63-218741/1988 and 54-13565/1979. As for these water-soluble films, it is allowed to use those available on the market, under the brand names of, for example, Solpuron (manufactured by Ai-Cello Chemical Co.), Hicellon (manufactured by Nichigo Film Co.) and pullulan (manufactured by Hayashibara Co.). In particular, Series of 7-000 of polyvinyl alcohol film available from Mono-Sol Division of Chris Craft Industries, Inc. can preferably be used, because it may be dissolved in water, without harm, at a temperature within the range of from 1.1 to 93.3°C (34°F to 200°F) and shows a high chemically resistant property. The above-mentioned water-soluble film preferably applicable thereto has a thickness within the range of from 10 to 120 µm preferably from 15 to 80 µm and more preferably from 20 to 60 µm, from the viewpoints of the preservation stability of a solid type processing composition, a period of time required for dissolving the water-soluble film and the crystal deposition produced inside an automatic processor. It is also preferable that a water-soluble film is of the thermoplastic type. This is not only because a heat-sealing process and a supersonic welding process may readily be performed, but also because a covering effect may more excellently be displayed. Further, the tensile strength of a water-soluble film is within the range of, preferably from 0.5x10 6 to 50x10 6 kg/m 2 , more preferably from 1x10 6 to 25x10 6 kg/m 2 and, particularly from 1.5x10 6 to 10x10 6 kg/m 2 . Such a tensile strength as mentioned above can be measured in conformity of the method specified in JIS Z-1521. A photographic processing composition packaged, bound or covered by a water-soluble film or a binder is preferably be packaged with a moisture resistive material, for such a purpose that high moisture including, for example, the atmospheric moisture such as rain and mist, and accidental damage produced by spattering or touching of the composition by wet hands may be prevented in the course of storing, transporting or handling the composition. As for such a moisture resistive material as mentioned above it is preferable to use a film having a thickness within the range of from 10 to 150 µm. The moisture resistive material is preferably at least one selected from the following film or a composite material thereof; namely, a polyolefin film such as those made of polyethylene terephthalate, polyethylene and polypropylene; a craft paper capable of showing a moisture resistant effect displayed by polyethylene; a wax paper; a moisture resistive cellophane; glassine, polyester, polystyrene, polyvinyl chloride, polyvinylidene chloride, polyamide, polycarbonate, acrylonitrile; a metal foil such as that made of aluminium; and a metallized polymer. In an embodiment of the invention, it is preferable to use a moisture resistive packaging material comprising a decomposable plastic including, particularly, a biodegradable or photolysable plastic. The biodegradable plastics include, for example, (1) a plastic comprising natural macromolecules, (2) a microbially produced polymer, (3) a synthetic polymer having good biodegradation properties, and (4) a plastic compounded with a biodegradable natural macromolecule. The photolysable plastics include, for example, (5) a plastic excited by UV rays and having a group capable of cutting a chain made present on the principal chain thereof. Besides the above-given macromolecules, those having both of the two functions, a photolysability and a biodegradability together, may effectively be used. Typical examples thereof will be given below. The biodegradable plastics include, for example, (1) A natural macromolecule; A polysaccharide, a cellulose, a polylactic acid, chitin, chitosan, a polyamino acid, or a modified derivative thereof; (2) A microbially produced polymer; "Biopol" comprising PHB-PHV (a 3-hydroxy butylate-3-hydroxy valeate copolymer) and a microbially produced cellulose; (3) A synthetic polymer having good biodegradation properties; A polyvinyl alcohol, a polycaprolactone, and a copolymer or a mixture thereof; and (4) A plastic compounded with a biodegradable natural macromolecule; A natural macromolecule having a good biodegradability includes starch and a cellulose. It is added to a plastic to provide a shape-decaying property to the compound. As for the examples of photo-degrading property, there are compounds where a carbonyl group is introduced. Besides, there may be some cases where a UV absorbent may be added to accelerate photo-degradation. As for such a decomposable plastic as mentioned above, those described in, for example, "Kagaku To Kogyo", Vol. 64, No. 10, pp. 478-484, (1990); and "Kinozairyo", July, 1990 Issue, pp. 23-34 can be used. It is also allowed to use the decomposable plastics available on the market including, for example, Biopol, by I.C.I., Eco, by Union Carbide.; Ecolite, by Eco Plastic Co.: Ecostar, by St. Lawrence Starch Co.; and Knuckle P, by Japan-Unicar Co., respectively. The above-mentioned moisture resistive packaging material has a moisture transmission coefficient of, preferably, not higher than 10 g·mm/m 2 /24 hrs and, more preferably, 5 g·mm/m 2 /24 hrs. As for the means of supplying a solid processing composition to a processing tank in the method of the invention and in the case that the solid processing composition is of the tablet type, for example, there is such a well-known means as described in JP Utility Model Nos. 63-137783/1988, 63-97522/1988 and 1-85732/1989. In short, any means can also be used for this purpose, provided, the means has at least a function for supplying a tablet to a processing tank. In the case that a solid processing composition is of the granule or powder type, there is a well-known means such as a gravitationally dropping type means described in Japanese Utility Model OPI Publication Nos. 62-81964/1987, 63-84151/1988 and JP OPI Publication No. 1-292375/1989 and such a propeller or screw type means as described in Japanese OPI Utility Model Publication Nos. 63-105159/1988 and 63-195345/1988. However, the invention shall not be limited thereto. As for a preferable means for supplying a solid processing composition to a processing tank, it may be considered to use such a means, for example, that a specific amount of a solid processing composition already weighed and separately put in a package in advance is opened and taken out of the package so as to meet the quantity of light sensitive material to be processed. To be more precise, a specific amount of a solid processing composition, that is preferably a replenishing amount thereof for each replenishment, is contained in a package that is sandwiched between at least two packaging materials, and the amount of the composition is then made to be in a state where it can be taken out by separating the packages to two directions or opening a part of the processing composition. The processing composition in the state where it can be readily taken out can be readily supplied to a processing tank provided with a filtering means by naturally dropping the composition. A specific amount of each processing composition is put in a separate tight-sealed package so that the atmospheric air and the aeration between it and any other solid processing composition adjacent thereto can be shielded. Therefore, the composition can be secured to resist any moisture invasion. In a particular embodiment of the invention, there is used a package comprising at least two packaging materials to sandwich a solid processing composition between the packaging materials, and the two packaging materials are brought into close contact with or are adhered to each surface thereof so that the surroundings of the processing composition can be separated apart. When the two packaging materials sandwiching the processing composition between them are pulled in different directions from each other, the close contacted or adhered surfaces are separated, so that the processing composition can be brought into a state where it is ready to be taken out. In another embodiment of the invention, a package may comprise at least two packaging materials to sandwich a solid processing composition between the packaging materials, and one of the two packaging materials can be opened by applying an external force. The expression "to open a package" herein means making use of a partial notch or partial cut of a packaging material, when the remaining material is unnotched or uncut. A method of opening a package is that compression is applied from a package on the non-opening side, through a solid processing composition, to the direction of the other package to be opened, so that the solid processing composition is forcibly pushed out. Or, a solid processing composition may be made ready to be opened by making a partial cut or notch on a package on the side where the package is to be opened by making use of a sharp-edged member. A supply starting signal is generated by detecting information on the amount of processing. A supply stopping signal is generated by detecting information on the completion of supply of a specified amount. When a processing agent is packaged separately and it is necessary to unseal it, upon reception of such a supply starting signal, the driving means for separation or opening, and upon reception of such a supply stopping signal, the driving means for separation or opening is disabled. The above solid processing agent supplying means is equipped with a controlling means for adding a given amount of the solid processing agent according to information on the amount of processing of light-sensitive material, which constitutes a key to the present invention. It is essential for the automatic processing machine which may be used according to the present invention to keep the component concentration in each processing tank constant and hence stabilize photographic performance. The information on the amount of processing of silver halide photographic light-sensitive material is a value in proportion to the amount of the silver halide photographic light-sensitive material to be processed by a processing solution or the amount of the silver halide photographic light-sensitive material already processed by a processing solution or the amount of the silver halide photographic light-sensitive material being processed by a processing solution, offering a direct or indirect index of the reduction in the amount of the processing agent in the processing solution. This information may be detected at any time, before or after light-sensitive material transportation into the processing solution or during its immersion in the processing solution. It may also be physical parameters such as the concentration of the processing solution contained in the processing tank, concentration change, pH or specific gravity or the amount discharged after drying the processing solution. Although any portion is acceptable to add the solid processing agent used in the method of the present invention, as long as it is located in the processing tank, preference is given to a portion communicating with the processing portion for the light-sensitive material and allowing the processing solution to flow to/from the processing portion. The preferred configuration is such that a given amount of processing solution is circulated to/from the processing portion to allow the dissolved components to be transferred to the processing portion. It is preferable to add the solid processing agent into a processing solution being warmed. Usually, the automatic processing machine is equipped with an electric heater to warm processing solutions, wherein, as a general method, a heat exchanger is provided in the auxiliary tank connected to the processing layer, which auxiliary tank is equipped with a pump for supplying the solution at constant rate from the processing tank to have constant temperature. A filter is usually arranged to remove crystalline foreign substances occurring due to contamination or crystallization in the processing solution. It is most preferable to add the solid processing agent to a warmed portion communicating with the processing portion like this auxiliary tank. This is because the insoluble components of the added processing agent are isolated from the processing portion by the filtering portion to prevent the solids from entering the processing portion and adhering to the light-sensitive material etc. so that dissolubility of the solid processing agent becomes extremely favorable. Also, when a processing agent receiving portion, along with the processing portion, is provided in the processing tank, it is preferable to provide a shield or another device to avoid direct contact of the insoluble components with the film etc. For the filter and filtering apparatus, any material can be used, as long as it is commonly used in ordinary automatic processing machines, and the effect of the present invention is not affected by any particular structure or material. The circulation cycle of a processing solution circulated by a circulating means in the invention is preferably from 0.5 to 2.0 cycles/min, more preferably from 0.8 to 2.0 cycles/min, from 1.0 to 2.0 cycles/min is specifically more preferable. Owing to this, dissolution of solid processing agents is accelerated, and thereby, occurrence of a group of high concentration solution, occurrence of uneven density of processed light-sensitive materials. Here, the circulation cycle is defined to be the flow amount of liquid circulated, and when a liquid amount corresponding to the total liquid amount in the processing tank is counted as one time. The processing solutions in processing tanks are preferably not less than 7 liters so that a processing property such as sensitivity or γ is not deteriorated, and more preferably not less than 10 liters. Especially, not less than 7 liters of the developer in a developing tank contribute to the effect of the invention. The solid processing composition used in the method of the present invention is added to the processing tank respectively separate from the replenishing water. Aforesaid replenishing water is supplied from the replenisher water tank. A mold-preventing means for a water-replenishing tank will be explained as follows. When the replacement rate in the water-replenishing tank falls to cause water to stay in the tank for a long time, scale is produced and after two or three hours from the formation of scale, water is decomposed and emits an offensive odor, which is a problem. Further, when the formed scale is directly mixed in a replenisher to be replenished, it adheres to the surface of a photographic light-sensitive material, causing streaks in the case of a color developing tank, causing insufficient desilvering in the case of a desilvering tank, and causing contamination in the case of a stabilizing tank. Thus, the scale deteriorates the value of finished commodities remarkably regardless of the type of a tank in which the scale is mixed. Therefore, it is necessary to clean periodically for removing the scale, which is very much time-consuming. Therefore, in order to remove this contamination, it is necessary to wash periodically, consuming extreme time. Therefore, a water-replenishing tank used according to the invention is provided with a mold-preventing means. The mold-preventing means can be attained by at least one means selected from the following group: Chelating agent adding means, Mold-preventing agent adding means, Deionizing processing means, UV irradiation means, Magnetic processing means, Ultrasonic processing means, Electrolytic sterilization means, Silver ion discharging means, Air-foaming means, Free radical releasing means, Means by contacting a multi-hole material, Means by adding other nonharmful bacteria.

A suitable support includes a plastic film. In order to enhance adhesivity of the surface of the support to a coating layer, a subbing layer may be provided on the support or corona discharge and UV ray irradiation may be given to the surface.

The emulsion layers provided on each side of the support may be the same as or different from each other. Fig. 1 is a plan view showing an example of a processing apparatus used in the method of the present invention. In the processing apparatus in Fig. 1, in both of a developing tank and a fixing tank, an anode and a cathode are separated from each other by an anion-exchange membrane (A membrane) 26 and 36 and a cation-exchange membrane (K membrane) 25 and 35 so that they are structured by an anode room (N room) 24 and 34, a cathode room (A room) 21 and 31, one or more condensation rooms (C room) 22 and 32 and one or more desalting rooms (D room) 23 and 33. First of all, liquid tank 20 will be explained. To the above-mentioned desalting room (D room) 23, waste of developing solution is circulated by means of pump 28. On the other hand, when an electrolytic solution such as sodium sulfate is circulated by means of pump 29 from the tank 27 to the anode room (N room) 24, the cathode room (A room) 21, and the condensation room (C room) 22, and an electric current flows across the anode and the cathode, halogenated ions in the waste are moved from the desalting room (D room) 23 to the condensation room (C room) 22 through anion-exchanging membrane 26 and removed. The halogenated ion collected to the condensation room (C room) 22 cannot pass the cation-exchanging membrane (K membrane) 25 even though it wants to move to the cathode side. Therefore, it cannot move from the condensation room (C room) 22. Therefore, the halogenated ion can effectively be removed. As shown in Fig. 1, the processing apparatus has a developing tank 11 filled with developing solution 110, a fixing tank 12 filled with fixing solution 120 and a washing tank 13. It transports light-sensitive material 10 such as an X-ray film through each processing tank to provide each processing step such as developing, fixing and washing. In developing tank 11 and fixing tank 12, liquid tanks 20 and 30 in each of which liquid is circulated freely with each tank. In addition, in each of liquid tanks 20 and 30, anion-exchange membranes (A membrane) 26 and 36 are located in a manner that each tank is divided into two or more rooms. Desalting room (D room) 23 is filled with developing solution 110. It is structured in a manner that liquid is communicated freely with a developing tank through a linkage tube. Condensation room (C room) in liquid tank 20 is filled with electrolyte solution 270. By the above-mentioned structure, developing solution 110 and electrolyte solution 270 are brought into contact through anion-exchanging membrane (A membrane). In anode room (N room) 24 in liquid tank 20, an anode is immersed. In cathode room (A room) 21 in liquid tank 20, a cathode is immersed. Liquid tank 30 is the same as liquid tank 20. Desalting room (D room) is filled with fixing solution 120. Condensation room (C room) is filled with electrolyte 370 from tank 37. These are brought into contact through anion-exchanging membrane 36. In addition, a processing apparatus wherein liquid tank 20 is composed only of an anode room (N room) and a cathode room (A room) can also be used. In this case, the anode room (N room) is filled with processing solution 110 and the cathode room (A room) is filled with electrolytic solution 270. The anode room (N room) and the cathode room (A room) are partitioned with an anion-exchange membrane (A membrane). In addition, a processing apparatus wherein liquid tank 30 is composed only of an anode room (N room) and a cathode room (A room) can also be used. In this case, the anode room (N room) is filled with processing solution 120 and the cathode room (A room) is filled with electrolytic solution 370. The anode room (N room) and the cathode room (A room) are partitioned with an anion-exchanging membrane (A membrane). By welding a halogenated substance ion in a processing solution, the halogenated substance ion passes through the anode room (N room) 24 and 34 and the anion-exchanging membrane to be moved to the cathode room (A room) 26 and 36 and removed. For welding, voltage may be impressed in a manner that electric current density is from 0.02 to 3 A/dm 2 and preferably from 0.05 to 1.2 A/dm 2 . Voltage to be impressed is completely different depending upon a solution used, form of the processing apparatus, distance between the electrodes and characteristics and kind of membrane. It is generally from 0.05 to 100V, and preferably from 0.1 to 10 V. In addition, the initial value of the membrane voltage is ordinarily from 0.5 to 20 V (the membrane resistance is from 0.5 to 30Ω). By means of the above-mentioned welding during processing of the light-sensitive material, halogen ions such as Br - which are accumulated in the developing solution and the fixing solution due to processing can be moved to the other electrode through the anion-exchange membrane. Therefore, the concentration of halogen ions in the processing solution can be kept constant. In addition, the processing component of the oxidized developing agent is reduced so that processing ability is recovered. Thus, a certain processing performance can be obtained. In the present invention, welding wherein electric current is constant is conducted. On this occasion, it may be controlled in a manner that the electric current per a unit volume (for example, 1 ℓ) of the processing solution (the current concentration) becomes constant. When only welding (for example, under fixed voltage, neither voltage nor electric current is controlled), an ampere-hour meter may be used for controlling. The reason for this is that, movement of the halogen ion and oxidation in a bleaching solution affect on the amount of welding by 80 to 99%. In this occasion, the current concentration shall ordinarily be from 0.5 to 50 A/ℓ and is preferably from 1 to 10 A/ℓ. Due to this control, the movement amount of anion ion can be controlled constantly. In this occasion, the electric amount necessary to recover developing power of the developing solution is different depending upon the adjustment of welding time. However, this electricity amount may be determined by the silver amount coated on the light-sensitive material and the amount of light-sensitive material carried over from the preceding bath. Anything can be used for the anion-exchange membrane used in the method of the present invention, provided that it permeates anion selectively. Commercially available ones can be used as they are. As the anion-exchange membrane, Selemion AMV/AMR (produced by Asahi Glass Co., Ltd.), Aciplex A201, A172 (produced by Asahi Kasei Co., Ltd.) and Nepton AR103PZL (produced by Ionics) can be used. However, since the object of the present invention is to permeate halogen ion such as Br - , it is preferable to use those which permeate mono-valent anion selectively such as Selmion ASV/ASR (produced by Asahi Glass Co., Ltd.), Neosepta AFN-7 and Neosepta ACS (produced by Tokuyama Soda). Incidentally, in the present invention, the above-mentioned anion-exchange membrane is a general name of a membrane which permeates anions selectively. In this meaning, it includes porous ceramics whose hole size is from 0.2 to 20 µm. In color photography practically, a processing solution used in the method of the present invention includes a color developing solution, the first black-and-white developing solution for reverse processing and a fixing solution. In black-and-white photography, it includes a black-and-white developing solution and a fixing solution. In the above-mentioned processing solution, following the advancement of processing, it is necessary to prevent accumulation of the halogen ions leached out from the emulsion layer in the light-sensitive material. On the other hand, a solution containing an electrolyte wherein a cathode is immersed may be a processing solution or one prepared separately. This one prepared separately is referred to as an electrolytic solution. As a processing solution, a processing solution having a bleaching ability such as a bleaching solution is cited. In the case of a bleaching solution, processing performance of the bleaching solution can be recovered by moving the halogen ions from the developing solution and the fixing solution to the bleaching solution by combining the bleaching solution with the color developing solution and the fixing solution and by oxidizing the bleaching agent reduced with the cathode. There is no limit to the electrolyte used for an electrolytic solution. However, it is preferable to use halides such as NaCl, KCl, LiCl, NaBr, KBr and KI, sulfate salts such as Na 2 SO 4 and K 2 SO 4 , nitrate salts such as KNO 3 , NaNO 3 , NH 4 NO 3 and carbonate salts such as Na 2 CO 3 and K 2 CO 3 . Of the above-mentioned various salts, when nitrate salts are used, nitric acid ion is replenished. Accordingly, replenishment of anti-corrosion agent and bleaching accelerator is decreased or, in some cases, they can be eliminated. When sulfate salts are used, sulfate ion is replenished. Therefore, replenishment of acid for reducing the pH can be decreased, or in some cases, eliminated. When carbonate salts are used, carbonate ion is replenished. Therefore, replenishment of a pH buffer agent and acid can be decreased, or in some cases, eliminated. Density of electrolyte in the electrolyte solution is ordinarily from 0.1 to 30% and preferably from 0.5 to 20%. The anion-exchanging membrane may be appropriately selected depending upon the kind of electrolyte solution. The anode used may be any electroconductor or semi-conductor capable of being used for a long time. Specifically, stainless steel is preferable. Anything can be used for the cathode provided that it is an insoluble material and an electric conductor. Practically, carbon (black lead), lead dioxide, platinum, gold and titanium steel are cited, and depending on opportunity, stainless steel may be used. The form of both electrodes is plate. Plate provided with net or a plate provided with a projection are preferable. Size may be selected appropriately depending upon the volume of the tank. The amount of replenishing water for dissolving a solid processing agent charged is ordinarily 300 cc/m 2 or less and preferably from 50 cc/m 2 to 150 cc/m 2 . In the present invention, the processing speed of the silver halide photographic light-sensitive material is ordinarily 20 m 2 /hr or more, and preferably from 30 m 2 /hr to 100 m 2 /hr. EXAMPLES The examples of the invention will be explained below, but the invention is not limited thereto. Example 1 The light sensitive material for evaluation was prepared as follows. (Preparation of light sensitive material) Preparation of seed emulsion-1 The seed emulsion-1 was prepared by the following method. Al Ossein gelatin 24.2 g Water 9657 ml Polypropyleneoxy-polyethyleneoxy-disuccinate sodium salt (10% ethanol solution) 6.78 ml Potassium bromide 10.8 g 10% nitric acid 114 ml B1 Aqueous 2.5N AgNO 3 solution 2825 ml C1 Potassium bromide 841 g Water was added to make 2825 ml. <Solution D> Aqueous 1.75N KBr solution an amount for controlling the following silver potential By the use of a mixing stirrer described in Japanese Patent Publication Nos. 58288/1983 and 58289/1982, 464.3 ml of each of Solution B1 and Solution C1 were added to Solution A1 in 1.5 minutes at 42°C by a double-jet method to form nuclei. After addition of Solutions B1 and C1 was stopped, the temperature of Solution Al was elevated to 60°C spending 60 minutes and adjusted to pH 5.0 using a 3% KOH solution. Then, solutions B1 and C1 each were added by means of a double jet method for 42 minutes at a flow rate of 55.4 ml/min. The silver potentials (measured by means of a silver ion selective electrode and a saturated silver-silver chloride reference electrode) during the temperature elevation from 42 to 60°C and during the re-addition of solutions B1 and C1 were regulated to + 8 mV and 16 mV, respectively, using Solution D1. After the addition, pH was regulated to 6 with 3% KOH. Immediately after that, it was subjected to desalting and washing. It was observed by an electron microscope that this seed emulsion was composed of hexahedral tabular grains, in which 90% or more of the total projected area of silver halide grains have a maximum adjacent side ratio of 1.0 to 2.0, having an average thickness of 0.064 µm, an average diameter (converted to a circle) of 0.595 µm. The deviation coefficient of the thickness is 40%, and the deviation coefficient of the distance between the twin planes is 42%. (Preparation of Em-1) The tabular silver halide emulsion Em-1 was prepared using the seed emulsion-1 and the following four kinds of solutions. A2 Ossein gelatin 34.03 g Polypropyleneoxy-polyethyleneoxy-disuccinate sodium salt (10% ethanol solution) 2.25 ml Seed emulsion-1 amount equivalent to 1.218 mol Water was added to make 3150 ml. B2 Potassium bromide 1734 g Water was added to make 3644 ml. C2 Silver nitrate 2478 g Water was added to make 4165 ml. D2 Fine grain emulsion composed of 3 weight % gelatin and silver iodide grains (averge grain size of 0.05 µ) amount equivalent to 0.08 mol A portion of Solution B2, a portion of Solution C2 and a half of Solution D2 were added to Solution A2 in 5 minutes at 60°C by a triple-jet method with vigorous stirring. Thereafter, a half of each of the remaining solutions B2 and C2 was added in 37 minutes, then, a portion of the remaining solutions B2 and C2 and the remaining solution D2 were added in 15 minutes, and finally, all of the remaining solutions B2 and C2 were added in 33 minutes. During this process, pH was maintained 5.8, and pAg 8.8. Herein, the addition rate of solutions B2 and C2 was varied as a function of time to meet a critical grain growing rate. Further, Solution D2 was added in an amount of 0.15 mol% of the total silver content to substitute a halide. After the addition, the resulting emulsion was cooled to 40°C, added with 1800 ml of an aqueous 13.8 weight % solution of modified gelatin as a polymer coagulant, which was modified with phenylcarbamoyl (substitution rate of 90%), and stirred for 3 minutes. Thereafter, a 56 weight % acetic acid solution was added to give a pH of 4.6, stirred for 3 minutes, allowed to stand for 20 minutes, and then the supernatant was decanted. Thereafter, 9.0 liter of 40°C distilled water were added, stirred, allowed to stand, and the supernatant was decanted. To the resulting emulsion were added 11.25 liter of distilled water, stirred, allowed to stand, and the supernatant was decanted. An aqueous gelatin solution and a 10 weight % sodium carbonate solution were added to the resulting emulsion to be pH of 5.8, and stirred at 50°C for 30 minutes to redisperse. After the redispersion, the emulsion was adjusted to give pH of 5.80 and pAg of 8.06. When the resulting emulsion was observed by means of an electron microscope, they were tabular silver halide grains having an average diameter of 1.11 µm, an average thickness of 0.25 µm, an average aspect ratio of about 4.5 and a grain size distribution of 18.1%. The average distance between the twin planes was 0.020 µm, and the grains having 5 or more of a ratio of the distance to the thickness was 97% (in number), the grains having 10 or more of the ratio 49%, and the grains having 15 or more of the ratio 17%. After the resulting emulsion (Em-1) was raised to 60°C, a spectral sensitizer was added in a specific amount in the form of a solid fine particle dispersion, and then a mixture solution of adenine, ammonium thiocyanate, chloroauric acid and sodium thiosulfate and a dispersion of triphenylphosphin selenide were added. Sixty minutes after the addition, the fine grain silver iodide emulsion was added, and the emulsion was ripened for total 2 hours. After completion of the ripening, 4-hydroxy-6-methyl-1,3,3a,7-tetrazaindene (TAI) was added for stabilizing. The addition amount per mol of AgX of the above additives is shown as follows. 5,5'-Dichloro-9-ethyl-3,3'-di-(sodiumsulfopropyl)-oxacarbocyanine anhydride 2.0 mg 5,5'-Di(butoxycarbonyl)-3,3'-di-(sodiumsulfobutyl)-benzoimidazolocarbocyanine anhydride 120 mg Adenine 15 mg Ammonium thiocyanide 95 mg Chloroauric acid 2.5 mg Sodium thiosulfate 2.0 mg Triphenylphosphin selenide 0.4 mg Silver iodide fine grain emulsion 280 mg 4-Hydroxy-6-methyl-1,3,3a,7-tetrazaindene (TAI) 500 mg The solid fine particle dispersion of the spectral sensitizing dye was prepared according to the method described in Japanese Patent Application No. 4-99437/1992. A specific amount of a spectral sensitizer was added to water at 27°C, and stirred at 3500 rpm for 30 to 120 minutes by means of a high speed stirrer (dissolver) to obtain a solid spectral sensitizing dye fine particle dispersion. The above selenium sensitizer dispersion was prepared as follows. Triphenylphosphin selenide was added in an amount of 120 g to 30 kg of 30°C ethyl acetate, and stirred to completely dissolve. Photographic gelatin in an amount of 3.8 kg was dissolved in 38 kg of pure water, and 93 g of a 25 wt% aqueous sodium dodecylbenzene sulfonate solution was added to obtain a gelatin solution. The above two solutions were mixed and dispersed at 50°C for 30 minutes in 40m/second of a dispersion blade periodical speed, using a high speed stirring dispersion machine having a stirring blade of a 10 cm diameter. Thereafter, the ethyl acetate was removed to obtain a 0.3 wt% residual concentration of ethyl acetate while stirring under reduced pressure. The resulting dispersion was diluted with water to make a 80 kg dispersion. The above emulsion was prepared using a portion of this dispersion. The silver halide grains contained in the above obtained silver halide emulsion (Em-1) had an average silver iodide content of 4 mol% on their surface. To the thus sensitized emulsion were added the following additives to obtain an emulsion layer coating solution. Further, a protective layer coating solution was prepared. The above obtained emulsion layer coating solution and the following protective layer coating solution were double layer coated in that order on each side of a blue colored 175 µm thick polyethylene terephthalate film support (a density of 0.15) coated with the following light shielding layer on each side, and dried.

Compound (O) C 11 H 23 CONH(CH 2 CH 2 O) 5 H <<Preparation of processing tablets>> A tablet developer replenisher was prepared in the following procedures (A) and (B). Procedure (A) In a bandam mill available on the market was pulverized 3000 g of hydroquinone, a developing agent to an average particle size of 10 µm. The resulting fine particles were added with sodium thiosulfate and potassium sulfite in an amount as shown in Table 1 and 1,000 g of dimeson S and mixed in a mill for 30 minutes. The resulting mixture was granulated by adding 30 ml of water at room temperature for about 10 minutes in a stirring granulator available on the market and dried at 40°C for 2 hours in a fluid-bed drier to almost completely remove water. The resulting granules were uniformly mixed in a mixer with 100 g of polyethylene glycol 6000 at 25°C and 40%RH or less, and the mixture was compression-tableted in an amount per tablet as shown in Table 1, using Tough Press Correct Model 1527HU produced by Kikusui Seisakusho Co., Ltd., which was modified. Thus, 2,500 tablets of each of developer replenishers A-1 through A-6 were obtained. Procedure (B) DTPA of 100 g, 4000 g of potassium carbonate, 10 g of 5-methylbenzotriazole, 7 g of 1-phenyl-5-mercapto-tetrazole, 5 g of 2-mercaptohypoxantine, 500 g of KOH and N-acetyl-D,L-penicilamine were pulverized and granulated in the same manner as in Procedure (A). The addition amount of water was 30.0 ml. After the granulation, the granules were dried at 50°C for 30 minutes to almost completely remove water. The resulting mixture was compression-tableted in an amount per tablet of 1.73 g, using Tough Press Correct Model 1527HU produced by Kikusui Seisakusho Co., Ltd., which was modified. Thus, 2,500 tablets of developer replenisher B were obtained. A tablet fixer replenisher was prepared in the following procedures. Procedure (C) Ammonium thiosulfate/sodium thiosulfate (70/30, weight ratio) of 14,000 g and sodium sulfite in an amount shown in Table 2 were pulverized and mixed in a mixer available on the market. The resulting mixture was granulated by adding 500 ml of water in the same manner as in Procedure (A). After the granulation, the granules were dried at 60°C for 30 minutes to almost completely remove water. The resulting granules were mixed with 4 g of sodium N-lauroylalanine in a commercial mixer at 25°C and 40%RH or less for 3 minutes and compression-tableted in an amount per tablet as shown in Table 2, using Tough Press Correct Model 1527HU produced by Kikusui Seisakusho Co., Ltd., which was modified. Thus, 2,500 tablets of each of fixer replenishers C-1 through C-4 were obtained. Procedure (D) Boric acid of 1000 g, 1500 g of aluminium sulfate octadecahydrate, 3000 g of sodium hydrogen acetate (obtained by mixing and drying an equimolecular glacial acetic acid and sodium acetate) and 200 g of tartaric acid were pulverized and granulated in the same manner as in Procedure (A). The addition amount of water was 100 ml. After the granulation, the granules were dried at 50°C for 30 minutes to almost completely remove water. The resulting granules were mixed with 4 g of sodium N-lauroylalanine for 3 minutes and compression-tableted in an amount per tablet of 4.562 g, using Tough Press Correct Model 1527HU produced by Kikusui Seisakusho Co., Ltd., which was modified. Thus, 1,250 tablets of fixer replenisher D were obtained. Developper starter Glacial acetic acid 2.98 g KBr 4.0 g Water was add to make 1 liter. The tablet developer was dissolved in diluting water to make a 16.5 liter developing solution and 330 ml of the starter was added thereto to prepare a developing starting solution. The developer tank was charged with the starting solution at the beginning of processing. The pH of the starting solution was 10.45. The fixer starting solution was prepared according to the following method. The fixer tank was charged with the fixer starting solution at the beginning of processing and the processing was carried out. Prescription of fixer Part A (for 18 liter) Ammonium thiosulfate (70wt/vol%) 6000 g Sodium sulfite 110 g Sodium acetate trihydrate 450 g Sodium citrate 50 g Gluconic acid 70 g 1-(N,N-dimethylamino)-ethyl-5-mercaptotetrazole 18 g Part B Aluminium sulfate 800 g Part A and Part B were added simultaneously to about 5 liter water and additional water was added with stirring to make a 18 liter solution. The pH was adjusted to pH 4.4 using sulfuric acid and NaOH. The above obtained light sensitive material was exposed to give a density of 1.0 after development and 2000 sheets of the material having a size of 25.4×30.5 cm (10×12 inches) were running processed. The processing was carried out using an automatic processor, SRX-502 (produced by Konica Corporation), which was equipped with an incorporating member of solid tablet and modified so that 45 second processing could be conducted. During the processing two tablets of the developer replenisher A, two tablets of the developer replenisher B and 76 ml water were added to a developer per 0.62 m 2 of light sensitive material. When tablets A and B were dissolved in 38 ml water, respectively, the pH of each solution was 10.70, and when two tablets of the developer replenisher A and two tablets of the developer replenisher B were dissolved in 76 ml water, the sulfite concentration in the solution was as shown in Table 1. The fixer replenishers C and D, and water in an amount shown in Table 3 were added to a fixer. Two tablets of the fixer replenisher C and one tablet of the fixer replenisher D were added per addition of 74 ml water. When two tablets of the fixer replenisher C and one tablet of the fixer replenisher D were dissolved in 74 ml water, the sulfite concentration in the solution was shown in Table 2. Water was added at the same time as the addition of each one tablet and the adding speed of water was almost in a proportion to the dissolving speed of each one tablet added.

Example 3 (Preparation of silver halide emulsion B) A silver halide emulsion was prepared in a double-jet precipitation method. In the process hexachloro rhodium complex was added in an amount of 8 × 10 -8 mol/mol of silver. After the conventional desalting, the resulting emulsion was proved to be an emulsion comprising cubic monodisperse grains containing 99 mol% of silver chloride and 1 mol% of silver bromide and having an average particle diameter of 0.10 µm (with a variation coefficient of 10%). To the resulting emulsion was added 4-hydroxy-6-methyl-1,3,3a,7-tetrazaindene, potassium bromide, citric acid and 3 × 10 -6 mol/mol of silver of an inorganic sulfur and the resulting emulsion was chemically ripened at 60°C to give the maximum density. After the ripening, 4-hydroxy-6-methyl-1,3,3a,7-tetrazaindene, 3 × 10 -4 mol per mol of silver of l-phenyl-5-mercaptotetrazole and gelatin were added to obtain silver halide emulsion B. (Preparation of silver halide photographic light-sensitive material) A 75 µm thick polyethylene terephthalate film subjected to anti-static treatment in the same manner as in Example 1 of Japanese Patent O.P.I.

The proccessing time was as follows: Processing conditions Development 35°C 8.2 seconds Fixing 33°C 5 seconds Washing Room Temp. 4.5 seconds Squeezing 1.6 seconds Drying 40°C 5.7 seconds Total 25 seconds As is apparent from Table 5, the fixability and drying properties were improved according to the invention. The effects of the invention were remarkable, especially when a sulfite ion was removed from the fixer. Further, the reduction of the amount of replenishing water for the fixer was also effective. Example 4 The light sensitive material prepared in Example 1 was processed in the same manner as in sample No. 9 of Example 1, except that automatic processor SRX-502 (produced by Konica Corporation) which was modified to be equipped with MICRO ACILYZER G3 (produced by Asahi Kasei Kogyo Co., Ltd.) was used. The MICRO ACILYZER G3 is a device for removing an ion from a solution through electrolysis. The dissolving speed or solubility of the tablets, sensitivity and residual silver were evaluated. The residual silver refers to silver remaining in the unexposed portions of the developed light sensitive material. The results exhibited improved dissolving speed or solubility, higher sensitivity and lower residual silver as compared with those obtained when an automatic processor without MICRO ACILYZER G3 was used. Example 5 Preparation of light sensitive material Preparation of seed emulsion-21 The seed emulsion-21 was prepared as follows. A21 Ossein gelatin 24.2 g Water 9657 ml Polypropyleneoxy-polyethyleneoxy-disuccinate sodium salt (10% ethanol solution) 6.78 ml Potassium bromide 10.8 g 10% nitric acid 114 ml B21 Aqueous 2.5N AgNO 3 solution 2825 ml C21 Potassium bromide 841 g Water was added to make 2825 ml. D21 Aqueous 1.75N KBr solution an amount for controlling the following silver potential By the use of a mixing stirrer described in Japanese Patent Publication Nos. 58288/1983 and 58289/1982, 464.3 ml of each of Solution B21 and Solution C21 were added to Solution A21 in 1.5 minutes at 42°C by a double-jet method to form nuclei. After addition of Solutions B21 and C21 was stopped, the temperature of Solution A21 was elevated to 60°C spending 60 minutes and adjusted to pH 5.0 using a 3% KOH solution. Then, solutions B21 and C21 each were added by means of a double jet method for 42 minutes at a flow rate of 55.4 ml/min. The silver potentials (measured by means of a silver ion selecting electrode and a saturated silver-silver chloride reference electrode) during the temperature elevation from 42 to 60°C and during the re-addition of solutions B21 and C21 were regulated to + 8 mV and 16 mV, respectively, using Solution D21. After the addition, pH was regulated to 6 with 3% KOH. Immediately after that, it was subjected to desalting and washing. It was observed by an electron microscope that this seed emulsion was composed of hexahedral tabular grains, in which 90% or more of the total projected area of silver halide grains have a maximum adjacent side ratio of 1.0 to 2.0, having an average thickness of 0.064 µm, an average diameter (converted to a circle) of 0.595 µm. The deviation coefficient of the thickness is 40%, and the deviation coefficient of the distance between the twin planes is 42%. (Preparation of Em-21) The tabular silver halide emulsion Em-21 was prepared using the seed emulsion-21 and the following four kinds of solutions. A22 Ossein gelatin 34.03 g Polypropyleneoxy-polyethyleneoxy-disuccinate sodium salt (10% ethanol solution) 2.25 ml Seed emulsion-1 amount equivalent to 1.218 mol Water was added to make 3150 ml. B22 Potassium bromide 1734 g Water was added to make 3644 ml. C22 Silver nitrate 2478 g Water was added to make 4165 ml. D22 Fine grain emulsion composed of 3 weight % gelatin and silver iodide grains (averge grain size of 0.05 µ) A portion of Solution B22, a portion of Solution C22 and a half of Solution D22 were added to Solution A22 in 5 minutes at 60°C by a triple-jet method with vigorous stirring. Thereafter, a half of each of the remaining solutions B22 and C22 was added in 37 minutes, then, a portion of the remaining solutions B22 and C22 and the remaining solution D22 were added in 15 minutes, and finally, all of the remaining solutions B22 and C22 were added in 33 minutes. During this process, pH was maintained 5.8, and pAg 8.8. Herein, the addition rate of solutions B22 and C22 was varied as a function of time to meet a critical grain growing rate. Solution D22 was added to give a halogen composition as shown in Table 6. After the addition, the resulting emulsion was cooled to 40°C, added with 1800 ml of an aqueous 13.8 weight % solution of modified gelatin as a polymer coagulant, which was modified with phenylcarbamoyl (substitution rate of 90%), and stirred for 3 minutes. Thereafter, a 56 weight % acetic acid solution was added to give a pH of 4.6, stirred for 3 minutes, allowed to stand for 20 minutes, and then the supernatant was decanted. Thereafter, 9.0 liter of 40°C distilled water were added, stirred, allowed to stand, and the supernatant was decanted. To the resulting emulsion were added 11.25 liter of distilled water, stirred, allowed to stand, and the supernatant was decanted. An aqueous gelatin solution and a 10 weight % sodium carbonate solution were added to the resulting emulsion to be pH of 5.8, and stirred at 50°C for 30 minutes to redisperse. After the redispersion, the emulsion was adjusted to give pH of 5.80 and pAg of 8.06. When the resulting emulsion was observed by means of an electron microscope, they were tabular silver halide grains having an average diameter of 0.91 µm, an average thickness of 0.20 µm, an average aspect ratio of about 4.5 and a grain size distribution of 18.1%. The average distance between the twin planes was 0.020 µm, and 97% (number) of the grains had a ratio 5 or more of the distance to the thickness, 49% of the grains had a ratio of 10 or more, and 17% of the grains had a ratio of 15 or more. After the resulting emulsion (Em-21) was raised to 60°C, a spectral sensitizer was added in a specific amount in the form of a solid fine particle dispersion, and then a mixture solution of adenine, ammonium thiocyanate, chloroauric acid and sodium thiosulfate and a dispersion of triphenylphosphin selenide were added. Sixty minutes after the addition, the fine grain silver iodide emulsion (in an amount of 0.3 mol% in terms of halogen composition) was added, and the emulsion was ripened for total 2 hours. After completion of the ripening, 4-hydroxy-6-methyl-1,3,3a,7-tetrazaindene was added for stabilizing. The addition amount per mol of AgX of the above described additives is shown as follows. Spectral Sensitizer (I) 2.0 mg Spectral Sensitizer (II) 120 mg Adenine 15 mg Potassium thiocyanide 95 mg Chloroauric acid 2.5 mg Sodium thiosulfate 2.0 mg Triphenylphosphin selenide 0.4 mg 4-Hydroxy-6-methyl-1,3,3a,7-tetrazaindene 2000 mg The solid fine particle dispersion of the spectral sensitizing dye was prepared according to the method described in Japanese Patent Application No. 4-99437/1992. A specific amount of a spectral sensitizer was added to water at 27°C, and stirred at 3500 rpm for 30 t0 120 minutes by means of a high speed stirrer (dissolver) to obtain a solid spectral sensitizing dye fine particle dispersion. The above selenium sensitizer dispersion was prepared as follows. Triphenylphosphin selenide was added in an amount of 120 g to 30 kg of 30°C ethyl acetate, and stirred to completely dissolve. Photographic gelatin in an amount of 3.8 kg was dissolved in 38 kg of pure water, and 95 g of a 25 wt% aqueous sodium dodecylbenzene sulfonate solution was added to obtain a gelatin solution. The above two solutions were mixed and dispersed at 50°C for 30 minutes in 40m/second of a dispersion blade periodical speed, using a high speed stirring dispersion machine having a stirring blade of a 10 cm diameter. Thereafter, the ethyl acetate was removed to obtain a 0.3 wt% residual concentration of ethyl acetate while stirring under reduced pressure. The resulting dispersion was diluted with water to make a 80 kg dispersion. The above emulsion was prepared using a portion of this dispersion. To the thus sensitized emulsion were added the following additives to obtain an emulsion layer coating solution. Further, a protective layer coating solution was prepared. The above obtained emulsion layer coating solution and the following protective layer coating solution were double layer coated in that order on each side of a blue colored 175 µm thick polyethylene terephthalate film support (a density of 0.15) coated with the following light shieding layer on each side, and dried.
