Description: Detailed Explanation of the Invention Field of the Invention The present invention relates to a solid processing composition for use in a silver halide photographic light sensitive material (hereinafter, referred to as a photographic material) and, in particular, to a solid processing composition superior in storage stability and with markedly shortened dissolution time, which provides improved silver stain (silver sludge) and residual color due to sensitizing dye residue when the light sensitive material is processed at a low replenishing rate. Background of the Invention Silver halide black and white photographic light sensitive materials for use in radiography, printing-plate making, microfilms and negative films have been processed with an alkaline developing solution containing hydroquinone as a developing agent and 3-pyrazolidone type or aminophenol type compound as an auxiliary developing agent. However, the hydroquinone has drawbacks with respect to safety in terms of biology and toxicology, and also such defects as heavy load in waste liquor treatments. As is well known, ethylene diols such as ascorbic acid have no problem in safety and act as a developing agent. However, compared to the hydroquinone developing solution, a developing solution containing ascorbic acid has problems such as the developing solution undergoing hydrolysis under high alkalinity to form an acid, thereby lowering the pH and losing chemical developing activity. In general, a large amount of a sulfite, which is commonly known as an antioxidant (preservative) is dissolved in a developing solution. However, the sulfite causes silver halide to dissolve out in the developing solution, leading to occurrence of stains due to silver which has been reduced in the developing solution (silver sludge). Further, in response to the desire for reduction of waste processing liquor, lowering of replenishing rates of a processing solution has been attempted. However, this resulted in problems not only of an increase of silver staining but also residual dye defects on processed films. Accordingly, improvements thereof have been sought. Conventionally, a processing composition is stored in plastic resin bottles in the form of a concentrated solution, and marketed and sold as a processing composition kit. The processing kit is diluted with water to prepare a working solution. However, since the processing kit is a concentrated solution, there are problems of safety. Further, it is quite heavy and needs more space for storage, resulting in increased transportation cost. In order to reduce these costs and promote safety, techniques for preparing the processing chemicals in the form of a tablet were considered. However, with regard to processing chemicals for the black-and-white photographic material, there is not only the problem described above, but also problems of the tablet-forming technique, including storage stability, lubricity during tablet formation by compression-molding, stability of the tablet and solubility in preparing a solution, and there problems have not yet been resolved. With regard to the stability of the tablet, in particular, processing is generally conducted under alkaline environments, resulting in a tablet containing an alkali agent, which produces a tablet poor in stability and, therefore, a technique for improvement thereof is eagerly sought. US 5272045 discloses a solid developer composition comprising five separate layers containing eg. sodium erythorbate in an amount of substantially less than 30% by weight. Summary of the Invention In response to the above-described problems, an objective of the present invention is to provide a solid processing composition superior in storage stability, lubricity during tablet formation by compression-molding, and stability of the tablet with markedly shortened dissolution time; and a processing method of the photographic material, showing reduced defects such as silver stain (which is also known as silver sludge) and reduced sensitizing dye residue.

A fixing solution used in the invention is preferably prepared through preparation of a solid fixing composition and its dissolution in water. Thiosulfates are preferably used as a fixing agent. Examples of the thiosulfates include a lithium, potassium, sodium or ammonium thiosulfate. Of these are preferred ammonium thiosulfate and sodium thiosulfate to obtain a fixing solution with a high fixing speed. Iodides or thiocyanates are also usable as the fixing agent. The fixing solution contains a sulfite. The sulfites include a lithium, potassium, sodium or ammonium sulfite. The fixing solution may contain a water soluble chromium salt or aluminum salt. Examples of the water soluble chromium salt or aluminum salt include chromium alum, aluminum sulfate, potassium aluminum chloride, aluminum chloride. The fixing solution may contain an acetate ion. The acetate ion is optionally usable and acetic acid and a lithium, potassium, sodium or ammonium acetate are preferably used. Of these, sodium or ammonium acetate is particularly preferred. Furthermore, citric acid, tartaric acid, malic acid, succinic acid, phenylacetic acid or an optical isomer thereof may be contained. There is also usable a lithium, potassium, sodium or ammonium salt, such as potassium citrate, lithium citrate, sodium citrate, ammonium citrate, lithium tartarate, potassium tartarate, sodium hydrogentartarate, sodium tartarate, ammonium tartarate, ammonium hydrogentartarate, ammonium potassium tartarate, sodium potassium tartarate, sodium malate, ammonium malate, sodium succinate and ammonium succinate. Of these compounds are preferred citric acid, isocitric acid, malic acid, phenylacetic acid and salts thereof. As other acids, inorganic acids such as sulfuric acid, hydrochloric acid, nitric acid and boric acid and organic acids such as formic acid, propionic acid, oxalic acid and malic acid are each usable. Boric acid and aminopolycarboxylic acids are preferably used. Aminopolycarboxylic acid such as nitrilotriacetic acid and ethylenediaminetetraacetic acid and salt thereof are used as a chelating agent. An anionic surfactant such as sulfuric esters and sulfonates, polyethylene glycol-type or ester-type nonionic surfactant, and amphoteric surfactant are used as a surfactant. As a lubricant is cited an alkanolamine or an alkylene glycol. As a fixing accelerator are cited thiourea derivatives, an alcohol having a triple bond and thioethers. The pH of the fixing solution is 3.8 or more and preferably from 4.2 to 5.5. The replenishing rate of the developing solution or the fixing solution is preferably not more than 15 ml per sheet of 25.4 x 30.5 cm (10x12 inch), from the point of reduction of effluent. Within this range of the replenishing rate, effects of the present invention are enhanced. In the invention, the solid processing composition is preferably in the form of granules or a tablet, and more preferably in the form of a tablet. Next, solidification of the processing composition will be described. The processing composition can be solidified in such a manner that the processing composition in the form of a concentrated solution, fine powder or granules is mixed with a water soluble bonding agent and then the mixture is molded, or the water soluble bonding agent is sprayed on the surface of temporarily-molded processing composition to form a covering layer, as described in JP-A 4-29136, 4-85533, 4-85534, 4-85535, 4-85536 and 4-172341. A preferred tablet-making process is to form a tablet by compression-molding after granulating powdery processing composition. As compared to a solid composition prepared simply by mixing the processing composition to form a tablet, there is an advantage that improvements in solubility and storage stability were achieved and resultingly, the photographic performance becomes stable. As for granulation process which is carried out prior to tablet-making process, any conventionally known method such as fluidized-bed granulation process, extrusion granulation process, compression granulation process, crush granulation process, fluid layer granulation process, and spray-dry granulation process can be employed. It is preferred that the average grain size of the granules is from 100 to 800 µm and preferably from 200 to 750 µm. In particular, 60% or more of the granules is with a deviation of ± 100 to 150 µm. When the grain size smaller, it tends to cause localization of mixing elements and therefore, is undesirable. As hydraulic press machine, any conventional compression molding machine, such as a single-engined compression molding machine, rotary-type compression machine, briquetting machine, etc. may be employed to form a tablet. Compression-molded (compression-tableted) solid processing composition may take any form and is preferably in a cylindrical form from the point of productivity, handleability and problems of powder dust. It is further preferred to granulate separately each component, such as an alkali agent, reducing agent and preservative in the above process. The processing composition in the form of a tablet can be prepared according to methods, as described in JP-A 51-61837, 54-155038, 52-88025, and British Patent 1,213,808. The granular processing composition can also be prepared according to methods as described in JP-A 2-109042, 2-109043, 3-39735 and 3-39739. The powdery processing composition can be prepared according to methods, as described in JP-A 54-133332, British Patent 725,892 and 729,862 and German Patent 3,733,861. The solid processing composition of the invention preferably has a bulk density of from 1.0 to 2.5 g/cm 3 from the viewpoint of solubility and the point of effects of the invention. When being not less than 1.0 g/cm 3 , it is advantageous for strength of the solid composition; and when being not more than 2.5 g/cm 3 , it is advantageous for solubility. In cases where the composition in the form of granules or powder, the bulk density is preferably from 0.40 to 0.95 g/cm 3 . A processing chemical having at least a part solidified and a solid processing chemical each applicable to the invention are included in the scope of the invention. It is, however, preferable that the whole component of these processing chemicals are solidified. It is also preferable that the components thereof are each molded into a separate solid processing chemical and then individually packed in the same form. It is further preferable that the components are packed in series in the order of periodically and repeatedly adding them from the packages. It is preferable that all the processing chemicals are solidified and are then replenished to the corresponding processing tanks so as to meet the information on a processing amount. When an amount of replenishing water is required, it is replenished in accordance with information on a processing amount or other information on replenishing water control. In this case, the liquids to be replenished to a processing tank can only be replenishing water. In other words, when a plurality of processing tanks are required to be replenished, the tanks for reserving some replenishing liquids can be saved to be only a single tank by making use of replenishing water in common, so that an automatic processor can be made compact in size. In particular for making the automatic processor compact in size, it is preferable to put a water replenishing tank on the outside of the automatic processor. A preferable embodiment of the solid processing composition of the invention is that all of an alkali agent, a developing agent and a reducer are solidified when solidifying a color developer, and that, when a color developer is tableted, the numbers of the tablets may be not more than 4 tablets and, preferably, a single tablet. When the solid processing chemicals are solidified separately into not less than 2 tablets, it is preferable to pack these plural tablets or granules in the same package. A moisture-proofed package for tablets or pills may be embodied of such a raw material as given below. As for a synthetic resin material, any one of the following materials may be used; namely, polyethylene (including any one prepared in either a high-pressure method or a low-pressure method), polypropylene (either non-stretched or stretched), polyvinyl chloride, polyvinyl acetate, Nylon (either stretched or non-stretched), polyvinylidene chloride, polystyrene, polycarbonate, Vinylon, Evarl, polyethylene terephthalate (PET), other polyesters, rubber hydrochloride, an acrylonitrile-butadiene copolymer and an epoxy-phosphoric acid type resin (a polymer described in JP OPI Publication Nos. 63-63037/1988 and 57-32952/1982), or pulp. The films of the above-given materials are usually made adhered to each other so as to be laminated. However, these materials may also be formed into a coated layer. It is further preferable to provide a gas-barrier layer thereto. For example, an aluminium foil or an aluminium vacuum-evaporated synthetic resin is sandwiched between the above-mentioned synthetic resin films. A total oxygen permeability of the above-mentioned laminated layers is, preferably, not higher than 50 ml/m 2 24 hr/atm (at 20°C and 65%RH) and, more preferably, not higher than 30 ml/m 2 24 hr/atm. A total thickness of the above-mentioned laminated layers is within the range of, preferably 1 to 2000µm, more preferably 10 to 1000µm and, further preferably 50 to 1000µm. The above-mentioned synthetic resin films may be comprised of a single (macromolecular) resin layer or not less than 2 laminated (macromolecular) resin layers. As for a single macromolecular resin layer capable of satisfying the requirements of the invention, for example, the following materials may be used thereto. (1) polyethylene terephthalate (PET) having a thickness of not thinner than 0.1mm, (2) an acrylonitrile-butadiene copolymer having a thickness of not thinner than 0.3mm, and (3) rubber hydrochloride having a thickness of not thinner than 0.1mm. Among them, polyethylene terephthalate can suitably be used, because it is also excellent in resistance to alkalinity and acidity.Next, for a laminated macromolecular resin layer capable of satisfying the requirements of the invention, for example, the following materials may be used thereto. (4) PET / a polyvinyl alcohol·ethylene copolymer (Evarl) / polyethylene (PE), (5) stretched polypropylene (OPP) / Eval / PE, (6) unstretched polypropylene (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) Evarl / PP, (18) PET / Al / PP, (19) paper / Al / PE, (20) PE / PVDC coated Nylon / PE / Ethyl vinyl acetate·polyethylene condensate (EVA), (21) PE / PVDC-coated N / PE, (22) EVA / PE / Al-vacuum-evaporated Nylon / PE / EVA, (23) Al-vacuum-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) can preferably be used. As for the concrete constituents of the packaging materials, the following examples of the constituents may be given in the order from the inside of a package, provided that the packing material side coming into contact with a processing chemical is regarded as the inside; PE / cardboard as a principal constituent / PE / Al / an epoxy-phosphoric acid type resin layer / a polyester type resin layer / PE, PE / K-Nylon / PE or an adhesive / Al / PE / cardboard / PE, PE / Vinylon / PE or an adhesive / Al / PE / cardboard / PE, PE / vinylidene chloride / PE or an adhesive / Al / PE / cardboard / PE, PE / polyester / PE or an adhesive / Al / PE / cardboard / PE, and Polypropylene / K-Nylon / polypropylene / Al / polypropylene /cardboard / polypropylene. The methods of moisture-proof-packaging tablets or pills include, for example, the following methods, namely, Four-side sealing, Three-side sealing, Stick-like sealing (including a pillow-like or cassette-like sealing), PTP sealing, and Cartridge sealing. The four-side sealing, 3-side sealing and stick-like sealing are classified by the shapes and these sealing methods can be applied to the above-given materials; provided when these sealing methods are utilized to a peel-open system, the sealing material is laminated with a sealant so that a peel-opening aptitude can be provided thereto. The above-mentioned peel-open system generally includes a cohesive failure system, an interface peeling system and an interlayer peeling system. The cohesive failure system is a system in which an adhesive called a hot-melt and a heat-seal lacquer are used as a sealer and a seal is peel-opened by cohesive failure in the inside of a sealant layer when the seal is to be opened. The interface peeling system is a system in which a peeling is made on the interface between two layers of film, and a sealing film (so-called a sealant) and a matter subject to adhesion are not completely fused together, so that the peel-opening can be made by applying an appropriate force. The sealants include a film prepared by mixing a viscous resin therein. The materials of such a film may be selected from polyethylene or the copolymers thereof and polyesters so as to meet the materials of the matter subject to the adhesion. The interface peeling system is a system in which a sealant is peeled apart between the layers of laminated films by making use of such a multilayer co-extruding film such as a laminated film. In a peel-open system applied with a film of the invention, an interlayer peeling system or a interface peeling system is preferably used. Such a sealant as mentioned above is relatively thin. Therefore, it is commonly used by laminating it on other film including, for example, those made of polyethylene, polypropylene, polystyrene, polycarbonate, a polyester (such as polyethylene terephthalate), polyvinyl chloride, Nylon, Evarl, and aluminium. From the viewpoints of moisture resistance, environmental protection and matching for a content of a package, polyethylene, polypropylene, polyester and Evarl may preferably be used. Taking a printability into consideration, it is preferable to use non-stretched polypropylene, polyester, paper sheet or the like as the outermost surface of a package. The above-mentioned sealants include, for example, CMPS film manufactured by Tocello Co., Diclan PP-100 and PS-300 each manufactured by Dai-Nippon Ink Mfg., Co., LTD film manufactured by Toppan Printing Co., and San-Seal FR and MS each manufactured by San-Ei Chemical Co., and so forth. The polyester-laminated types thereof include, for example, Diclan C-1600 and C-1602T and so forth. The above-mentioned PTP is a blister packaging form in which a solid processing chemical is put on a molded sheet made of PVC, CPP or the like and it is then heat-sealed with an aluminium material. From the viewpoint of environmental protection, there is a tendency to avoid PVC from being used as a molding material. Recently, A-PET and a highly moisture-resistive PP (such as TAS-1130, TAS-2230 and TAS-3230 each manufactured by Taisei Chemical Industrial Co., Ltd.) have preferably been used. When packing, binding or covering a processing chemical by making use of a water-soluble film or a binder, the water-soluble film or binder preferably applicable thereto include, for example, those comprising a basic material of a polyvinyl alcohol type, methyl cellulose type, polyethylene oxide type, starch type, polyvinyl pyrrolidone type, hydroxypropyl cellulose type, pullulan type, dextran type, gum arabic type, polyvinyl acetate type, hydroxyethyl cellulose type, carboxyethyl cellulose type, sodium carboxymethyl hydroxyethyl cellulose type, poly(alkyl) oxazoline type and polyethylene glycol type. Among them, those of a polyvinyl alcohol type and a pullulan type can more preferably be used from the viewpoint of the covering or binding effect. The preferable polyvinyl alcohol is a very effective material for forming a film, because it has an excellent strength and flexibility under almost any conditions. Polyvinyl alcohol compositions available on the market, which are molded into a film, have various degrees of molecular weight and hydrolysis. However, the polyvinyl alcohol compositions are preferable to have a molecular weight within the range of 10000 to 100000, approximately. The term, "a degree of hydrolysis", herein means a ratio of the acetic acid group of polyvinyl alcohol is substituted by a hydroxyl group. When polyvinyl alcohol is applied to a film, the range of the hydrolysis is ordinarily within the range of 70% to 100% approximately. As mentioned above, the scope of the polyvinyl alcohol ordinarily include a polyvinyl acetate compound. The above-mentioned water-soluble films can be prepared in such an ordinary process as described in JP-A 2-124945, 61-97348, 60-158245, 2-86638, 57-117867, 2-75650, 59-226018, 63-218741/1988 and 54-13565. As for the water-soluble films, those available on the market under the brand names such as Solvlon (manufactured by Ai-Cello Chemical Co.), Hi-Cellon (manufactured by Nichigo Film Co.) or Pullulan (manufactured by Hayashibara Co.) may be used. Besides the above, a 7-000 series of polyvinyl alcohol films available from the MONO-SOL Division of Chris Craft Industries, Inc. can particularly preferable to be used, because these films can be dissolved in water at a temperature of 1.1 to 93.3°C (34°F to 200°F) approximately and they can show a high chemical resistance without any harmfulness. From the viewpoints of the preservability of a solid processing chemical, the dissolving time of a water-soluble film and the crystal deposition in an automatic processor, the layer thickness of the water-soluble film is to be within the range of, preferably from 10 to 120µm, particularly from 15 to 80µm and, inter alia from 20 to 60µm. The water-soluble films are preferable to be thermoplastic, because a heat-sealing or supersonic fusing treatment can readily be performed and a covering effect can more excellently be displayed. The tensile strength of a water-soluble film is to be 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 . The tensile strength is measured in the method specified in JIS Z-1521. A photographic processing chemical packed, bound or covered by a water-soluble film or a binder is preferable to be packed in a moisture-resistive packaging material so as to be protected from high moisture, moisture in the air such as rain and mist, and accidental damage produced by bringing the package into contact with water by scattering water or by wet hands in the course of storing, transporting or handling the package. The moisture-resistive packaging materials include preferably a film having a thickness within the range of from 10 to 150µm. The material thereof is preferably at least a material selected from the group consisting of a polyolefin film such as those of polyethylene terephthalate, polyethylene and polypropylene, a sheet of craft paper capable of having a moisture-resistive effect displayable with polyethylene, waxed sheet of paper, moisture-resistive cellophane, glassine, polyester, polystyrene, polyvinyl chloride, polyvinylidene chloride, polyamide, polycarbonate, acrylonitrile and a metal foil such as those of aluminium, and a metallo- polymer. They may also be a compounded material of the above-given material. It is also preferable that a moisture-resistive packaging material is made of a decomposable plastic including particularly a biodegradable or photolyzable plastic. The biodegradable plastics include, for example, (1) those comprising a natural macromolecule, (2) a microbial growing polymer, (3) a synthetic polymer having a good biodegradation property, and (4) a compound of a biodegradable natural macromolecule to a plastic. The photolyzable plastics include, for example, (5) those having a group made present in the principal chain so as to be excited by UV rays and then coupled to a scission. Besides the above-given macromolecules, those having the two functions of a photolyzing and biodegrading properties at the same time may also effectively be used. The typical and concrete examples thereof may be given as follows. The examples of the biodegradable plastics may be given as follows; (1) natural macromolecules, namely, A polysaccharide, cellulose, polylactic acid, chitin, chitosan, polyamino acid, and the modified thereof; (2) microbial growing polymers, namely, "Biopol" comprising PHB-PHV (that is a copolymer of 3-hydroxybutylate and 3-hydroxybarrelate), and microbial growing cellulose; (3) a synthetic polymer having a good biodegradation property, namely, polyvinyl alcohol, polycaprolactone and the copolymer or mixture thereof; (4) a compound of a biodegradable natural macromolecule to a plastic, namely, a natural macromolecule having a good biodegradation property such as starch and cellulose, which is added to a plastic so that a configuration decaying property can be provided to the plastic. (5) photolyzable plastics, namely, those introduced thereinto with a carbonyl group for providing a photodecaying property, and those added thereto with a UV absorbent for accelerating a decaying property. As for such a decomposable plastics as mentioned above, those publicly described in, for example, "Chemistry and Industry", Vol. 64, No. 10, pp. 478-484, (1990); "The Kino Zairyo", July, 1990 Issue, pp. 23-34; may be used. Besides the above, it is also allowed to use the decomposable plastics available on the market, such as Biopol (manufactured by I.C.I.), Eco (manufactured by Union Carbide Corp.), Ecolite (manufactured by Eco Plastics, Inc.), Ecostar (manufactured by St.Lawrence Starch Co.) and Nackle P (manufactured by Japan-Unicar, Inc.). The above-mentioned moisture-proofed packaging materials are to have a moisture permeability coefficient of not higher than 10 g·mm/m 2 ·24hr and, preferably not higher than 5 g·mm/m 2 ·24hr. As for the means for supplying a solid processing chemical to a processing tank, and in the case where the solid processing chemical is of the tablet type, for example, there are such a well-known means as described in Japanese Utility Model OPI Publication Nos. 63-137783/1988, 63-97522/1988 and 1-85732/1989, wherein, in short, any means may be used, provided that at least a function for supplying a tableted chemical to a processing tank can be performed. And, in the case where the solid processing chemical is of the granulated or powdered type, there are such a well-known means such as the gravity dropping systems described in JP OPI Publication Nos. 62-81964/1987, 63-84151/1988 and 1-292375/1989, and the screw system described in JP OPI Publication Nos. 63-105159/1987 and 63-84151/1988. Among them, however, a preferable means for supplying a solid processing chemical to a processing tank is such a means, for example, that a prescribed amount of a solid processing chemical is weighed out in advance and is then separately packed and the package thereof is opened and the chemical is then taken out of the package so as to meet the quantity of light-sensitive materials to be processed. To be more concrete, every prescribed amount of a solid processing chemical and, preferably, every amount for a single replenishment is sandwiched between at least two packing materials constituting a package. When separating the package into two directions or opening a part of the package, the solid processing chemical can be ready to take out thereof. The solid processing chemical ready to be taken out thereof is readily be supplied to a processing tank having a filtration means by naturally dropping the chemical. The prescribed amounts of the solid processing chemicals are each separately packed respectively in a tightly sealed package so as to shut off the open air and the air permeability to any adjacent solid processing chemicals. Therefore, the moisture resistance can be secured unless the packages are opened. A processing package may comprise at least two packing materials sandwiching a solid processing chemical therebetween, which is brought into close contact with or made adhered to the peripheries of the solid processing chemical on each of the contacting surfaces of the two packing materials so as to be separable from each other, if required. When each of the packing materials sandwiching the solid processing chemical therebetween is pulled each in different directions, the close contacted or adhered surfaces are separated from each other, so that the solid processing chemical can be taken out. In a package comprising at least two packing materials sandwiching a solid processing material therebetween, at least one of the packing materials thereof can be designed to open the seal by applying an external force. The expression, "to open a seal", stated herein means that a packing material is notched or broken off as a part of the packing material remains unnotched or unbroken off. It may be considered to open a seal in such a manner that a solid processing chemical is forcibly extruded by applying a compression force from the side of a packing material subject to be unopened through a solid processing chemical to the direction of a packing material made ready to be opened, or that a solid processing chemical can be taken out by notching a packing material subject to be opened by making use of a sharp-edged member. A supply-starting signal can be obtained by detecting information on a processing amount. Based on the obtained supply-starting signal, a driving means for separation or opening a seal is operated. A supply-stopping signal can be obtained by detecting information on the completion of a specific amount of supply. Based on the obtained supply-stopping signal, a driving means for separation or opening a seal is so controlled as to be stopped in operation. The above-mentioned solid processing chemical supplying means has a means for controlling the addition of a specific amount of the solid processing chemical, that is an essential requirement for the invention. To be more concrete, in an automatic processor, these means are required to keep every component concentration constant in each processing tank and to stabilize every photographic characteristic. The term, "an information of the processing amount of silver halide photographic light-sensitive materials", means an information on a value obtained in proportion to an amount of silver halide photographic light-sensitive materials to be processed with a processing solution, to an amount of silver halide photographic light-sensitive materials already processed or to an amount of silver halide photographic light-sensitive materials being processed, and the values indicate indirectly or directly an amount of a processing chemical reduced in a processing solution. The values may be detected at any point of time before and after a light-sensitive material is introduced into a processing solution or during the light-sensitive material is dipped in the processing solution. An amount of a light-sensitive material printed by a printer may also be detected for this purpose. A concentration or concentration variation of a processing solution reserved in a processing tank may further be detected. An amount discharged to the outside after a processing solution is dried up may also be detected. A solid processing composition of the invention may be added to any position inside a processing tank and, preferably, to a position communicated with a section for processing a light-sensitive material and circulating a processing solution between the processing tank and the processing section. It is also preferable to have such a structure that a certain amount of processing solution can be circulated therebetween so that a dissolved component can be moved to the processing section. It is further preferable that a solid processing chemical is added to a thermostatically controlled processing solution. Generally in an automatic processor, the temperature of a processing solution loaded therein is controlled by an electric heater. As for a general method thereof, a heat exchanger section is provided to an auxiliary tank connected to a processing tank and a heater is also provided thereto, and a pump is further arranged so as to circulate a given amount of the solution from the processing tank to the auxiliary tank and keep the temperature constant. For the purpose of removing a crystallized foreign substance contained in a processing solution or produced in a crystallization, a filter is usually arranged. It is allowed to connect a replenishing tank to a section connected to a processing section, such as the above-mentioned auxiliary tank. When the composition of the invention is used in an automatic processor preferably the circulation frequency of a processing solution circulated by a circulation means is to be within the range of from 0.5 to 2.0 times/minute, preferably from 0.8 to 2.0 times/minute and more preferably from 1.0 to 2.0 times/minute. The expression, "a circulation frequency", herein is related to a flow rate of a liquid to be circulated, and one circulation herein means when a liquid amount corresponding to the total liquid amount reserved in a processing tank is flowed out. The solid processing composition is added to the processing tank, separately from the replenishing water. The replenishing water is supplied from the water storage tank. Now, an antimolding means of a water replenishing tank of an automatic processor which may be used with the composition of the invention will be detailed. When the liquid exchange rate of the water replenishing tank is lowered so that the water retention time is prolonged, there may be the problem that fur is produced and a bad smell is also produced after 2 to 3 weeks, because water contained in the tank is spoilt. If fur produced is replenished as it is, there may be the serious problem that the fur adheres to a photographic material so that a development unevenness is produced when the fur adheres to the developing tank, and fixing failure is produced so that the commercial value is seriously spoilt when the fur adheres to the fixing tank. Therefore, every tank is to be cleaned up periodically for removing fur, so that it takes much time and requires much labor. Therefore, the water supplying tank preferably has antimolding means. The antimolding means can be achieved by at least one means selected from the group consisting of the following means. 1) A chelating agent adding means, 2) An antimold adding means, 3) A deionizing means, 4) A UV-ray irradiating means, 5) A magnetic treating means, 6) A supersonic treating means, 7) An electrolytic pasteurizing means, 8) A silver-ion releasing means, 9) An air bubbling means, 10) An active oxygen releasing means, 11) A means for coming into contact with a porous material, 12) A means for adding other harmless fungus to prevent any multiplication of harmful fungi. Now, the above-mentioned means will concretely be detailed. As for the chelating agents and pasteurizers applicable to serve as an antimolding means, the following compounds can be used for example. The chelating agents preferably include, for example, ethylenediamine tetraacetic acid, diethylenetriamine pentaacetic acid, 1-hydroxyethylidene-1,1-diphosphonic acid, ethylenediamine tetra(methylene phosphonic acid), 2-hydroxy-4-sulfophenol and 2-hydroxy-3,5-disulfophenol. The pasteurizers include, for example, a phenol type compound, a thiazole type compound and a benztriazole type compound. To be more concrete, the preferable compounds thereof include, for example, 1,2-benzisothiazoline-3-one, 2-methyl-4-isothiazoline-3-one, 2-octyl-4-isothiazoline-3-one, 5-chloro-2-methyl-isothiazoline-3-one, Sodium O-phenylphenol and benztriazole. When these compounds are collectively packed in one lot, they are preferable to be in the tablet form. When they have been dividedly weight in advance, they are preferable to be packed individually in an amount for a single usage. As for the means for adding the chelating agent and pasteurizer, it is allowed that a chemical preparator may add them by hand. It is however preferable that a solid processing composition supply device is provided and they may be added thereby, and it is more preferable that a detector is provided to a water replenishing tank and they are automatically added when water is replenished up to a certain level of the tank, from the viewpoint of maintenance-free. A means for modifying water with an ion-exchange resin can be embodied according to the means described in, for example, JP-A. 61-131632(1986). The above-mentioned ion-exchange resins include, for example, various kinds of well-known cation-exchange resins (such as a strong acid type cation-exchange resin and a weak acid type cation-exchange resin) and various kinds of anion-exchange resins (such as a strong base type anion-exchange resin), of which are described in Technical Reports Laid Open to Public Inspection No. 90-473 and so forth. They may be used singly or in combination. It is ordinarily preferable to use a strong acid type H cation-exchange resin and a weak base type OH anion-exchange resin. It is also allowed either that they may be provided to a water replenishing tank, or that water may be modified at a separate place.

Example 2 To the same granules as those used in Sample 9 of Example 1 was added a compound represented by formula (3) as shown in Table 2, and mixed for 3 min. by a mixer in a room controlled at 25° C and 40% RH. The resulting mixture was subjected to compression-tableting according to the manner described below to obtain a developing composition in the form of a tablet. Evaluation of lubricity: Using a commercially available hydraulic press machine and die with a diameter of 30 mm, the granular mixture was subjected to compression-molding at a compression pressure of 7000 kg/cm 2 so as to have a filling amount of 10 g per tablet. In this case, pressure necessary for taking out a tablet from the die was measured by a load cell. Repeating this procedure five time, the average value of the pressure, which was referred to as releasing pressure, was compared as a measure of lubricity of the tablet. Evaluation of hardness: Five tablets of each tablet sample obtained by the above procedure were measured with respect to hardness, using a hardness tester (TS-50N, produced by Okada Seiko Co.) and the average value thereof was evaluated as a hardness (or strength) of the tablet. Evaluation of abrasiveness: Tablet samples were allowed to stand for 1 week under the condition at 25° C and 40% RH. Thereafter, five tablets of each sample were put in a tablet abrasion tester (product by Kayagaki Rika Kogyo Co.); after rotating for 5 min., the surface of the tablet was brushed off and the tablets were evaluated with respect to degree of abrasion, according to the following equation. The smaller is the value, the higher is the stability of the tablet. Degree of abrasion = {[Tablet weight before testing (g) - Tablet weight after testing (g)]/Tablet weight before testing (g)}x100 Results thereof are shown in Table 2.

The resulting granules were dried up at 40° C for 2 hr. in a fluidized bed drier so that the moisture content of the granules was almost completely removed off. Further, the granules were subjected to dressing with a dressing machine provided with 1.0 mm mesh to obtain granules (B). Preparation of solid developing composition in the form of tablet: To the thus prepared granules (B) was added an exemplified compound 3-3 and mixed for 10 min. by making use of a mixer in a room controlled to be not higher than 25° C and 40% RH. The mixture was subjected to compression-molding to form a tablet so as to have a filling amount of 10 g per tablet, by making use of a tableting machine that was modified model of Tough Press Collect 1527HU manufactured by Kikusui Mfg. Works, Inc to obtain alkaline composition-tablets for use in development.

Preparation of granules (D): Boric acid of 600 g, aluminum sulfate octadecahydrate of 1480 g, cinnamic acid of 1100 g and tartaric acid of 300 g each were pulverized up in a commercially available mill so as to have an average particle size of 10 µm. To the resulting fine particles, was added D-sorbit of 50 g and D-mannit of 250 g and, in stirring granulator commercially available, the resulting mixture was granulated by adding 30 ml of water. The resulting granules were dried up at 50° C for 2 hr. in a fluidized bed drier so that the moisture content of the granules was almost completely removed off. Further, the granules were subjected to dressing with a dressing machine provided with 1.0 mm mesh to obtain granules (D).

Preparation of processing solutions for use in processor: A developing solution for use in the processor was prepared by dissolving developing composition tablets A and B in water to make a total amount of 1 liter. The tablets A and B each were prepared by compression-molding the granules (A) or (B), so as to have a concentration of the sulfite or carbonate, as shown in Table 5. In this case, the tablets were completely dissolved and no precipitate was observed. Thus prepared developing solution of 7.8 1 was introduced into a processor SRX-201 (product by Konica Corp.) and a starter having the composition as below was added thereto in amount of 40 ml/l to prepare a starting developing solution. A fixing solution for use in the processor was prepared by dissolving fixing composition tablets C and D (24 tablets and 4 tablets, respectively) in water to make a total amount of 1 liter. The tablets C and d each were prepared by compression-molding the granules (C) and (D). In this case, the tablets were also completely dissolved and no precipitate was observed.

Processing was carried out at a developing temperature of 34' C, fixing temperature of 34° C and drying temperature of 55° C over total period of 60 sec. The replenishing rate was 14 ml per sheet of 25.4 x 30.5 cm (10x12 inch). Preparation of photographic light sensitive material First, a light-sensitive material for evaluation purpose was prepared in the following manner. Preparation of light-sensitive material Preparation of Seed Emulsion-1: Seed emulsion-1 was prepared in the following manner. A1 Ossein gelatin 24.2 g Water 9657 ml Sodium polypropyleneoxy-polyethyleneoxydisuccinate (in an aqueous 10% ethanol solution) 6.78 ml Potassium bromide 10.8 g 10% nitric acid solution 114 ml B1 Aqueous 2.5N silver nitrate solution 2825 ml C1 Potassium bromide 841 g Add water to make 2825 ml D1 An aqueous 1.75N potassium bromide solution An amount for controlling the following silver potential To Solution A1, Solutions B1 and C1 were each added in an amount of 464.3 ml at 42°C by making use of a mixing stirrer shown in examined and published Japanese Patent 58-58288 and 58-58289 in a double-jet process by taking 1.5 minutes, so that nucleus grains were formed. After stopping the addition of Solutions B1 and C1, the temperature of Solution Al was raised to 60°C by taking 60 minutes and the pH thereof was adjusted to be 5.0 by making use of a 3% KOH solution. Thereafter, Solutions B1 and C1 were each added thereto again at a flow rate of 55.4 ml/min. for 42 minutes in the double-jet process. At the time for raising the temperature from 42°C to 60°C and the time for the subsequent double-jet process carried out with Solutions B1 and C1, the silver potential (measured by a silver-ion selection electrode together with a saturated silver-silver chloride electrode as a control electrode) was so controlled as to be +8 mv and +16 mv by making use of Solution D1, respectively. After the completion of the addition, the pH was adjusted to be 6 with a 3% KOH solution and a desalting treatment were immediately made. The resulting seed emulsion was proved through an electron microscope as follows. Not less than 90% of the whole projected area of the silver halide grains thereof were comprised of hexagonal, tabular-shaped grains having the maximum adjacent edge ratio within the range of 1.0 to 2.0; and the average thickness and average grain-size (converted into the diameter of the corresponding circle, i.e., circle equivalent diameter) of the hexagonal tabular grains were proved to be 0.064 µm and 0.595 µm, respectively. Further, the variation coefficients of the grain thickness and the distance between the twin planes thereof were proved to be 40% and 42%, respectively. Preparation of emulsion, Em-1: By making use of Seed emulsion-1 and the following 4 kinds of solutions, silver halide tabular grain emulsion Em-1 was prepared. A2 Ossein gelatin 34.03 g S-3 (in an aqueous 10% ethanol solution) 2.25 ml Seed emulsion-1 Equivalent to 1.218 mols Water to make 3150 ml B2 Potassium bromide 1734 g Water to make 3644 ml C2 Silver nitrate 2478 g Water to make 4165 ml D2 A fine-grained emulsion comprising 3 wt% of gelatin and silver iodide grains (having an average grain-size of 0.05 µ) Equivalent to 0.080 mols In a reaction vessel, Solution A2 was vigorously stirred with keeping the temperature at 60°C. Thereto a part of Solution B2, a part of Solution C2 and the half amount of Solution D2 were each added in a triple-jet process by taking 5 minutes. Thereafter, the half amounts each of the remaining Solutions B2 and C2 were added successively by taking 37 minutes and, finally, the whole remaining amount of Solutions B2 and C2 were each added by taking 33 minutes. In the above-mentioned courses, the pH and pAg thereof were kept at 5.8 and 8.8 for all the while. Wherein, the flowing rates of Solutions B2 and C2 were acceleratedly varied so as to meet the critical growth rate. Further, the above-mentioned Solution D2 was added in an amount equivalent to 0.15 mol% of the whole silver amount, so that a halogen conversion was performed. After completing the additions, the resulting emulsion was cooled down to 40°C and, thereto, 1800 ml of an aqueous solution of 13.8 wt% of gelatin modified with a phenylcarbamoyl group (substitution ratio of 90%), was added as a polymeric flocculant. The resulting emulsion was then stirred for 3 minutes. Thereafter, an aqueous 56 wt% of acetic acid solution was added thereto. The pH of the emulsion was adjusted to be 4.6. The emulsion was stirred for 3 minutes and was then allowed to stand for 20 minutes. The resulting supernatant was removed away by means of a decantation. Then, 9.0 liters of distilled water having a temperature of 40°C was added. After stirring and then allowing it to stand, the resulting supernatant was removed away and 11.25 liters of distilled water was further added thereto. After stirring and allowing it to stand, the resulting supernatant was removed away. Successively, an aqueous gelatin solution and an aqueous 10 wt% sodium carbonate solution were added and the pH thereof was adjusted to be 5.80. The resulting solution was stirred at 50°C for 30 minutes and was then redispersed. After completing the redispersion, the pH and pAg thereof were adjusted at 40°C to be 5.80 and 8.06, respectively. When observing the resulting silver halide emulsion through an electron microscope, it was proved to be the tabular-shaped silver halide grains having the average grain-size of 1.11 µm, the average thickness of 0.25 µm, the average aspect ratio of about 4.5 and the grain-size distribution of 18.1%. The average distance between the twin planes of the grains was 0.020 µm. In the ratio of the distance between the twin planes to the grain thickness, the grains having not lower than 5 thereof were proved to account for 97% (in numbers) of the total tabular-shaped silver halide grains. Those having not less than 10 were proved to account for 49% of the total grains, and those having not less than 15 accounted for 17% thereof. Next, the resulting emulsion (Em-1) was raised to be 60°C and a given amount of a spectral sensitization dye was added thereto in the form of a solid fine-grain dispersion. After adding it, an aqueous mixed solution of adenine, ammonium thiocyanate, chloroauric acid and sodium thiosulfate and a dispersion of triphenyl phosphine selenide were added and, after 60 minutes, a silver iodide fine-grained emulsion was added. Then, a chemical-ripening treatment was carried out for two hours in total. At the time of completing the ripening treatment, a given amount of 4-hydroxy-6-methyl-1,3,3a,7-tetrazaindene (TAI) was added as a stabilizer. The above-mentioned additives and the amount of them added (per mol of AgX) are shown below.

To be more concrete, they were prepared in such a manner that a given amount of the spectral sensitization dye was added to water thermally controlled to be 27°C and it was stirred at 3,500 rpm by making use of a high-speed dissolver for a period within the range of 30 to 120 minutes. The dispersion of the above-mentioned selenium sensitizer was prepared in the following manner. Thus, 120 g of triphenylphosphine selenide was added to 30 kg of ethyl acetate kept at 50°C and then so stirred as to be dissolved completely. On the other hand, 3.8 kg of photographic gelatin was dissolved in 38 kg of water and, thereto, an aqueous 25 wt% of sodium dodecylbenzene sulfonate was added. Next, these two solutions were mixed up and the resulting mixture was dispersed at 50°C for 30 minutes by making use of a high-speed stirring disperser provided with a 10-cm dissolver at a dispersion blade speed of 40 m/sec. Thereafter, the remaining ethyl acetate was removed while stirring was rapidly carried out under reduced pressure so that the ethyl acetate concentration could be not higher than 0.3 wt%. Then, the resulting dispersion was diluted by making use of pure water so as to make 80 kg.
