Description: INDUSTRIAL FIELD OF THE INVENTION The present invention relates to a solid processing composition and a method for processing a silver halide photographic light sensitive material, and particularly to a solid processing composition and a method for processing a silver halide photographic light sensitive material for graphic arts. BACKGROUND OF THE INVENTION Processing of silver halide photographic light sensitive materials is accomplished mainly with an automatic processor, due to stability, easiness, speed and handlability. Dihydroxybenzenes (mainly, hydroquinone) are used as a developing agent in almost all developers for processing a silver halide black-and-white photographic light sensitive material. However, the use thereof have problems that the developer blackening occurs due to aerial oxidation and hydroquinone polymer (referred to as scum) produced as a byproduct is adhered to the conveying rollers in the processor or to a processed photographic material, resulting in deterioration in quality of the finished photographs. A means for solving these problems is replacement of hydroquinone as a developing agent by ascorbic acid. However, processing by using (replenishing), over a long period of time, these developers which are disclosed in U.S. Patent 5,236,816 and WO 93/11456 resulted in marked lowering of activity of the developer and insufficient process stability. The improvement has been eagerly sought. US-A-2 688 549 discloses developing compositions including a 3-pyrazolidone, ascorbic acid or sugar derivatives which can contain sodium cations. The compositions are presented in powder form. SUMMARY OF THE INVENTION Accordingly, an object of the invention is to provide a solid processing composition and a method for processing a silver halide photographic light sensitive material using a developer containing ascorbic acid or its derivative as a developing agent, wherein running stability is markedly increased, even when a large amount of light sensitive material are processed in a reduced replenish amount of developer replenisher.

As a particular case in which the developing agent is contained in the light sensitive material, for example, in the emulsion layer or in its adjacent layer, the light sensitive material may be developed with an alkali solution, which is an activator processing solution. Such a light sensitive material may be also developed with developer. Such a development is often used as one of rapid processes in combination with silver stabilizing treatment of a thiocyanate, and the compounds of the invention can be applied thereto. A fixer having a conventional composition can be used. The fixer is usually an aqueous solution comprised of a fixing agent and other additives, and has a pH of 3.8 to 5.8. As the fixing agent, thiosulfates such as sodium thiosulfate, potassium thiosulfate or ammonium thiosulfate, thiocyanates such as sodium thiocyanate, potassium thiocyanate or ammonium thiocyanate, or organic sulfur compounds capable of producing soluble stable silver complexes can be used.

The acetic acid ion content of the fixer is more preferably 0.22 mol or less per liter, and especially preferably 0.13 mol or less per liter, which can minimize acetic acid gas production. It is most preferable that the fixer contains no acetic acid. The fixer preferably contains a thiosulfate.

Of these, the stabilizer preferably contains anti-molds. These agents can be replenished in a liquid or solid form. When replenished in a solid form, the solid composition can be prepared or employed according to the method described above. In the invention, in order to minimize a waste solution, light sensitive material is processed while a specific amount of developer and fixer replenisher is replenished in proportion to an area of the light sensitive material to be processed. The replenishing amounts of the developer and fixer replenisher are 330 ml or less, preferably 30 to 200 ml per m 2 of light sensitive material. The replenishing amount of the developer and fixer replenisher herein referred to is a liquid amount replenished. When the mother developer and fixer developer are replenished, the replenishing amount is a replenishing amount thereof. When a concentrated developer and its diluting water, and a concentrated fixer and its diluting water are replenished, the replenishing amount is a total replenishing amount of the concentrated developer and its diluting water, and a total replenishing amount of a concentrated fixer and its diluting water. When a developer in which a solid developer is dissolved in water and a fixer in which a solid fixer is dissolved in water are replenished, the replenishing amount is a total volume of the solid developer and water, and a total volume of the solid fixer and water, respectively. When a solid processing composition is directly replenished in a processing tank of an automatic processor, the replenishing amount is preferably represented in terms of a total volume of the solid processing composition and water separately replenished. The developer replenisher and fixer replenisher may be the same as or different from a mother developer in the developer tank and a fixer developer in the fixer tank in an automatic processor, or may be also a solid developer or solid fixer. Particularly, when the developer replenisher is replenished in an amount of 120 ml or less per m 2 of light sensitive material, the replenisher is preferably different from a mother developer in the developing tank of an automatic processor or a solid developer. The content of an anti-sludging agent having a mercapto group contained in the developer replenisher is preferably higher than that in the mother developer. The content of a compound of the invention represented by formula (1-a) or a transition metal complex in the developer replenisher is preferably 1.2 to 4 times higher than that in the mother developer. Particularly, when the fixer replenisher is replenished in an amount of 150 ml or less per m 2 of light sensitive material, the fixer replenisher is preferably different from a mother fixer in the fixer tank of an automatic processor or a solid fixer. The content of a thiosulfate contained in the fixer replenisher is preferably higher than that in the mother fixer. The solid processing composition in the invention may be dissolved in water. The temperatures of developer, fixer, washing and stabilizing bath are preferably from 10°C to 45°C, and may be adjusted separately. In the invention, when using an automatic developing apparatus, the total processing time (Dry to Dry processing time) is preferably 10-150 seconds. The total processing time is the time taken from the entry of the leading edge of a film in the apparatus to the delivery of the tail end of the film out of the drying zone of the apparatus. The total processing time referred to herein is the total time necessary to process black-and-white silver halide photographic light-sensitive material, and concretely, the time necessary to carry out the steps, developing, fixing, bleaching, washing or stabilizing and drying, which is Dry to Dry time. Dry to Dry processing time less than 10 seconds results in desensitizing and low contrast, and does not exhibit satisfactory results. Dry to Dry processing time is more preferably 25 to 120 seconds. In order to running process stably 10 m 2 or more of light sensitive material, developing time is preferably 2-45 seconds. In order to markedly effect the invention, an automatic processor preferably comprises a drying zone in which heat conductors of 60°C or more (for example, a heat roller of 60-130°C or more) or heat radiation materials of 150°C or more (for example, a material such as tungsten, carbon, nichrome, zirconium oxide-yttrium oxide·thorium mixture or silicon carbide emitting an infrared light by applying electric current or a heat heat conductor such as copper, stainless steel, nickel, or ceramics heated by transfer of heat from heat radiation materials) are provided. The heat conductor of 60°C or more includes a heat roller. The heat roller is preferably an aluminium hollow roller covered with a silicone rubber, polyurethane or teflon. Both ends of the heat roller are preferably supported rotatably by bearings made of a heat resistant resin (for example, Rulon) embedded in side walls of a drying zone. A gear is provided at one end of the heat roller, and preferably is rotated in the conveying direction by a driving means or a drive transmission means. The heat roller contains a halogen heater therein which preferably connects a temperature controller provided in an automatic processor. The temperature controller connects a thermistor contact-provided at the periphery of the heat roller. It is preferable that the temperature controller controls a temperature to switch on or off the halogen heater so that a temperature detected by the thermistor is within the range of 60 to 150°C, preferably 70 to 130°C. The heat radiation materials of 150°C or more (preferably 250°C or more) include the followings: tungsten, carbon, tantalum, nichrome, zirconium oxide-yttrium oxide·thorium mixture, silicon carbide, molybdenum bisilicide or lanthanum chromate. The heat radiation is controlled by applying electric current to the materials or by transfer heat from the materials to a heat conductor such as copper, stainless steel, nickel, or ceramics. In the invention a combination of a 60°C or more heat conductor and a 150°C or more heat radiation material may be used. further, a conventional 60°C or less heated air may be used in combination. The silver halide composition of the silver halide emulsion used in the invention is not limited, but when processed with reduced replenishment of a processing solution or rapidly processed, a silver halide emulsion containing silver chloride, or silver bromochloride or bromoiodochloride having a silver chloride content of 60 mol% or more is preferable. The average grain size of the silver halide grains is preferably not more than 1.2 µm, and more preferably 0.1 to 0.8 µm. The average grain size is common in the photographic art and commomly used technical term. The grain size herein referred to is a grain diameter when grains are spherical or approximately spherical. When cubic, the size is a diameter in terms of spheres. A method of measuring the average grain size is detailed in T.H. James, "The Theory of the Photographic Process", the third edition, p. 36-43, (1966, issued by Mcmillan Co. Ltd.). The silver halide grain shape is not specifically limited, and may be tabular, spherical, cubic, tetradecahedral, octahedral and the like. The grain size distribution is preferably narrow, and the silver halide emulsion is preferably a monodisperse emulsion in which 90% or more preferably 95% or more of the grains fall within the range of ±40% of the average grain size. As a method of reacting a soluble silver ion with a soluble halide in the manufacture of a silver halide emulsion, a normal precipitation method, a double jet precipitation method or a combination thereof can be used. A method of forming grains in the presence of an excess silver ion, so-called a reverse precipitation method can be used. As one method of the double jet precipitation, a method of maintaining pAg of the silver halide forming solution constant, so-called a controlled double jet method can be used. According to this method, silver halide grains of regular shape having an approximately uniform grain size. In order to markedly effect the invention, it is preferable that the silver halide emulsion of at least one silver halide emulsion layer comprises tabular grains in which 50% or more of the total grain projected area are a total projected area of tabular grains having an aspect ratio of 2 or more. As the tabular grains increases to 60%, 70% and 80%, the preferable results are obtained. The aspect ratio is a ratio of a distance between two parallel planes to a diameter of a circle having the same area as a projected area of tabular grains. The silver halide grains having a silver chloride content of 50 mol% or more have a major face (100), and can be represented in terms of a longitudinal/lateral length ratio instead of the aspect ratio. The length ratio is preferably 1.2 to 8. The nuclear forming site inside grains may contain iodine in an amount of 0.001 to 1 mol%. The tabular silver halide grains having a high content of silver chloride is disclosed in US Patent No. 5,320,938. It is preferable in view of pressure resistance of grains that the inner portions of the grains have a high silver iodide content of 0.001 to less than 10% or silver nuclei. As the aspect ration or longitudinal/lateral length ratio increases, grains are more tabular. The preferable thickness is 0.01 to 0.5 µm, but can be selected depending on the aspect ratio and an average volume grain diameter of grains. The silver halide emulsion is preferably a monodisperse emulsion in which grain diameter distribution is 30% or less, especially 20% or less. The distribution is represented by grain diameter variation coefficient, a grain diameter standard variation R divided by the diameter D, S/D x 100, the grain diameter being a diameter of a circle corresponding to a projected area of the grains. The tabular grains and normal crystal grains can be used in combination. The tabular silver halide grains are preferably tabular grains having a silver chloride content of 50 mol% or more and a major face (100). These grains are disclosed in US Patent Nos. 5,264,337, 5,314,798 and 5,320,958, and can be easily obtained. The tabular grains can be prepared to epitaxially grow silver halide having a different composition at the specific surface or cover the surface with the silver halide. The grains can be prepared to have a transition line inside the grains in order to control sensitivity nuclei. The transition line can be formed by carrying chemical sensitization in the presence of silver iodide fine particles or an iodine ion. The silver halide grains are preferably doped with a metal under an acidic condition of pH 1-5. In order to control grain growth during formation, silver halide solvents such as ammonia, thioethers, thioureas and thions can be used. The emulsion may contain a metal such as zinc, lead, thallium, iridium, rhodium, ruthenium, osmium, palladium, or platinum. In order to obtain high intensity properties, the silver halide grains are often doped with iridium in an amount of 10 -9 to 10 -3 per mol of silver halide. In the invention, in order to obtain a high contrast emulsion, the silver halide grains are preferably doped with rhodium, ruthenium, osmium or rhenium in an amount of 10 -9 to 10 -3 mol per mol of silver halide. A metal complex, in which halogen, carbonyl, nitrosil, amine, cyan, thiocyan, ammonia, tellurocyan, selenocyan, dipyridyl, tripyridyl, phenanthroline or a compound thereof is coordinated with a metal, is added to silver halide grains. The oxidation condition of a metal is selected from the maximum oxidation level to the minimum oxidation level. The preferable ligand is a hexadentate ligand disclosed in Japanese Patent O.P.I. Publication Nos. 2-2082/1990, 2-20853/1990, 2-20854/1990 and 2-20855/1990, a sodium, potassium or cesium salt as an alkalicomplex or a primary, secondary or tertiary amine salt. A transition metal complex can be formed as an aquocomplex. The example includes K 2 [RuCl 6 ], (NH 4 ) 2 [RuCl 6 ], K 2 [Ru(NO)Cl 6 (SCN)], and K 2 [RuCl 5 (H 2 O)]. A compound in which Ru in the example is replaced with Rh, Os, Ir, Pd or Pt can be used. A rhodium, ruthenium, osmium or rhenium compound is preferably added during formation of silver halide grains. There is a method of uniformly dispersing the compound in the grains or localizing the compound at a core or shell portion of a core/shell structure. The silve halide grains having more of the compound in the shell gives good results. A method of continuously incresaing the amount in the outerward may be used in addition to a method localizing the compound in the incontinuous phase. The addition amount of the compound is optionally selected in the range of from 10 -9 to 10 -3 mol per mol of Ag. The silver halide emulsion and the preparing method thereof are detailed in Research and Disclosure (RD), 176, 17643, p. 22-23 (December, 1978) or in references cited in the same. The silver halide emulsion may be chemically sensitized or may not. The chemical sensitization method includes sulfur, reduction, selenium, tellurium or noble metal sensitization, and this may be used singly or in combination. The sulfur sensitizer may be a conventional sulfur sensitizer, but the preferable sulfur sensitizer includes various sulfur compounds such thiosulfates, thiourea, rhodanines or polysulfides, in addition to a sulfur compound contained in gelatin. The selenium sensitizer may be a conventional selenium sensitizer, and is preferably those disclosed in US Patent No. 1,623,499, and Japanese Patent O.P.I. Publication Nos. 50-71324/1985 and 60-150046/1985. The tellurium sensitizer may be a conventional tellurium sensitizer, and is preferably those disclosed in US Patent Nos. 1,623,499, 3.772,031 and 3,320,069. The typical noble metal sensitization is gold sensitization. The complex of a noble metal other than gold, for example, platinum, palladium or rhodium can be used. The reduction sensitizer includes stannous salts, amines, formamidines, sulfinic acids or silane compounds. When this sensitizer is added in a fine particle dispersion, sensitization is increased. When AgI grains are added in a fine particle dispersion during chemical sensitization, AgI is formed on the surface of grains and dye sensitization is increased. When AgI is formed on tabular grains, contribution of transition lines of 0 to 1000 is often used. The silver halide emulsion can be spectrally sensitized by sensitizing dyes. The sensitizing dyes includes cyanine dyes, merocyanine dyes, complex cyanine dyes, complex merocyanine dyes, holopolar cyanine dyes, hemicyanine dyes, styryl dyes or hemioxonol dyes.

Gelatin includes limed gelatin, acid processed gelatin, gelatin hydrolysate or enzyme decomposed gelatin. The photographic emulsion in the invention may contain water insoluble or sparingly soluble synthetic polymer in order to improve dimensional stability. The synthetic polymer includes polymers obtained by polymerization of alkyl(meth)acrylate, alkoxyacryl(meth)acrylate, glycidyl (meth)acrylate, (meth)acryl amide, vinylester such as vinyl acetate, acrylonitrile, olefin, styrene or a combination thereof, or its combination with acrylic acid, methacrylic acid, α,β-unsaturated dicarboxylic acid, hydroxyalkyl(meth)acrylate, sulfoalkyl(meth)acrylate or styrene sulfonic acid. As a method of markedly effecting the invention, at least one photographic layer preferably contains a hydrophilic polymer. The hydrophilic polymer includes starch, glucose, dextrin, dextrane, cyclodextrin, sucrose, maltose, and carrageenin. The hydrophilic polymer has a molecular weight of 600 to 1,000,000. The lower the molecular weight is, the better, in view of rapidly dissolving in a processing solution , but 600 or more molecular weight is necessary, since too low molecular weight results in lowering of film strength. Since the hydrophilic polymer reduces film scratch resistance, the film preferably contains an inorganic substance such as colloidal silica, colloidal tin, colloidal zinc, colloidal titanium, colloidal yttrium, colloidal placeodium, neodynium, zeolite, or apatite. The zeolite includes analcite, erionite, mordenite, shabacite, gmelinite, levynite, and the synthetic zeolite includes zeolite A, X, Y and L. The apatite includes hydroxy apatite, fluorine containing apatite and chlorine containing apatite. The addition amount of the inorganic substance is preferably 1 to 200% by weight based on the weight of the hydrophilic binder. when the inorganic substance is surface treated with a silane coupling agent, an emulsion is difficult to coagulate, a coating solution is stabilized and a crack produced due to the inorganic substance is prevented. The silane coupling agent includes triethoxysilanovinyl, trimethoxysilanovinyl, trimethoxypropylmethacrylate, trimethoxysilanopropylglycidyl, 1-mercapto-3-triethoxysilanopropane, 1-amino-3-triethoxysilanopropane, triethoxysilanophenyl, and triethoxymethylsilane. The silane coupling agent is high temperature treated in the prescence of the inorganic substance whereby properties are improved as compared with a simple mixture thereof. The mixing ratio of the agent to the inorganic substance is 1:100 to 100:1. It is preferable that the silver halide photographic light sensitive material in the invention comprises a support, a silver halide emulsion layer thereon, at least one hydrophilic colloid layer on the surface of the support opposite the emulsion layer and at least one hydrophobic polymer layer on the hydrophilic colloid layer. The hydrophilic colloid layer includes a backing layer. In the invention at least one hydrophobic polymer layer is preferably provided on the backing layer. The hydrophobic polymer layer in the invention cotains a hydrophobic polymer as a binder. The example of the binder includes polyethylene, polypropylene, polystyrene, polyvinyl chloride, polyvinylidene chlore=ide, polyacrylonitrile, polyvinyl acetate, a urethane resin, a urea resin, a melamin resin, a phenol resin, an epoxy resin, fluorine resins such as tetrafluoroethylene and polyvinylidene fluoride, rubbers such as butadiene rubbers, chloroprene rubbers,and natural rubbers, acrylates or methacrylates such as polymethyl methacrylate and polyethylacrylate, polyesters such as polyethylene terephthalates, polyamides such as nylon-6 and nylon-66, a water insoluble polymer such as silicone resins and their derivatives.

These polymers may be used singly or in combination. The hydrophobic polymer layer optionally contains a photographic additives for example, a matting agent, a surfactant, dyes, a slipping agent, a cross-linking agent, a thickener, a UV absorber and inorganic fine particles such as colloidal silica. These additives are disclosed in Research Disclosure 176, Section 17646 (December, 1978). The hydrophobic polymer layer may be a single or two or more layers. The thickness of the hydrophobic polymer layer is not specifically limited, but when the hydrophobic polymer layer is too thin, water resistance is insufficient and a backing layer swells in a processing solution. In contrast, when the hydrophobic polymer layer is too thick, a moisture permeation is insufficient of the layer and moisture absorption or desorption of the hydrophilic backing layer is inhibited, resulting in anti-curling property lowering. The thickness of the hydrophobic polymer layer depends on physical properties of a binder used. Accordingly, the thickness is determined considering both. The thickness of the hydrophobic polymer layer is 0.05 to 10 µm, preferably 0.1 to 5 µm, although it depends on the kinds of binders used. The method of coating a hydrophobic polymer layer is not limited. After a backing layer is coated and dried, a polymer layer may be coated and dried on the backing layer, or a backing layer and a hydrophobic polymer layer may be coated simultaneously and dried. The hydrophobic polymer layer may be coated using a solution in which the binder is dissolved in a solvent or an aqueous dispersion in which the binder is dispersed in water. A hydrophobic polymer layer is preferably provided on a backing layer on the surface of a support opposite the silver halide emulsion layer of a silver halide photographic light sensitive material, the backing layer being coated on the support surface with an adhesive layer, an antistatic layer and a hydrophilic colloid layer in that order.

The adhesive layer is provided on a support by coating a vinylidene chloride copolymer or a styrene-glycidyl acrylate copolymer on a support subjected to corona discharge to give a thickness of 0.1 to 1 µm and then coating thereon a gelatin layer containing tin oxide or vanadium pentoxide fine particles having an average diameter of 0.01 to 1 µ doped with indium or phosphor. A styrene sulfonic acid-maleic acid copolymer layer can be cross-linked by a cross-linking agent such as aziridine or a carbonyl active agent as described above. A dye backing layer may be provided on the anti-static layer. The backing layer may contain an inorganic filler for dimensional stability such as colloidal silica, silica or a methyl methacrylate matting agent for anti-slipping, a lubricant for controlling transportability or a release agent. The backing layer may contain a backing dye. The backing dye includes a benzilidene or oxonol dye. These alkali soluble or decomposable dyes can be fixed in a form of fine particles. The dye concentration for anti-halation is preferably 0.1 to 2.0 in each spectral sensitive wavelength range.

The hardeners may be used singly or in combination. These hardeners are disclosed in Research Disclosure, 176, 17643 (December, 1978), P. 26, Sections A to C. The carboxy activated hardener is especially preferable, and the compounds represented by formulas (1) through (7) on pages 3 to 5 of Japanese Patent O.P.I. Publication No. 5-289219/1993 are preferable and the examples thereof include H-1 through H-39 on pages 6 to 14 of the Japanese Patent. The photographic emulsion or non-light sensitive hydrophilic colloid layer in the invention may contain a coating auxiliary or various conventional surfactants to prevent static, improve sliding property, help emulsify, prevent adhesion, and improve photographic properties. Each layer may contain a hydrophilic polymer such as dextrins, starch or glicose in addition to gelatin to adjust degree of swell of the layer. The degree of swell is preferably 120 to 200. Each layer is dried adjusting a drying time or temperature according to the moisture evaporating speed. The drying temperature is 25 to 200°C, and the drying time is 0.1 to 200 seconds. The degree of swell is obtained by measuring sample immersed in water through a microscope or a swell meter. The degree of swell is represented in terms of the following value: Ld (a dry thickness after storage at 23°C and 50% RH for 24 hours) x 100/ Lw (a swell thickness after immersing in 23°C water) The surface tension or wetting index is obtained according to a JIS method. The film surface pH on the silver halide emulsion side is preferably 4.5 to 5.8. The film surface pH is measured after coating and drying. It is obtained by dropping 1 cc water on a film of 1cm 3 and measuring pH through a pH meter. When pH is lowered, an acid such as citric scid, oxalic acid, hydrochloric acid, sulfuric acid, nitric acid, acetic acid or hydrogen carbonate is used, and hen pH is elevated, an alkali agent such as sodium hydroxide, potassium hydroxide, sodium carbonate, sodium bicarbonate or sodium acetate is used. When pH is adjusted on addition of photographic additives, a similar method is used. The light sensitive material in the invention optionally contains other various photographic additives. The example includes a desensitizing agent, a plasticizer, a slipping agent, a developing accelerator and oil. The support used in the light sensitive material in the invention may be transparent or non-transparent, but preferably a transparent plastic support. The plastic support includes a support made of polyethylenes (for example, polyethylene terephthalate or polyethylene naphthalate), triacetates (for example, cellulose triacetate) and polystyrenes. Of these, an oriented film support (hereinafter referred to as SPS) made of a syndiotactic polystyrene or a composition containing the same is especially preferable. The SPS is comprised of a styrene homopolymer having a syndiotactic structure but includes a SPS modified with a small amount of a second component (for example, in an amount of 20 mol% or less, preferably 10 mol% or less, more preferably 5 mol% or less. The second component includes an olefin such as ethylene, propylene, butene or hexene, a diene such as butadiene or isoprene, a cyclic olefin monomer, a cyclic diene monomer and a polar monomer such as methyl methacrylate, maleic anhydride or acrylo nitrile. The SPS is obtained by polymerizing styrene or its derivative in the presence of an organic metal catalyst under an appropriate reaction condition. The syndiotactic polystyrene has not less than 75%, preferably not less than 80% of a recemi diad, or not less than 30%, preferably not less than 50% of a recemi pentad. The SPS may contain a conventional plasticizer as a second component, as long as bending elasticity is not deteriorated, and contains the plasticizer for an appropriate bending elasticity. SPS is obtained by polymerizing styrene or its derivative in the presence of a titanium compound or trialkylaluminium compound at an appropriate temperature. This method is disclosed in Japanese Patent O.P.I. Publication Nos. 62-187708/1987, 1-46921/1989 and 1-178505/1989. The polymerization degree of SPS is not specifically limited, but the molecular weight of the SPS is preferably 10,000 to 5,000,000. In order to increase bending elastisity of SPS, an optimum orientation condition need be selected. The unoriented film is firstly oriented in the londitudinal direction by 3.3 ± 0.3 times at a temperature within 30 ± 25°C of the film transition temperature, that is, at a temperaturew of 120 ±25°C, and then oriented in the lateral direction by 3.6 ± 0.6 times at the same temperature. After the orientation, heat treatment is carried out at 230 ± 18°C. Two steps of the heat treatment are preferably carried out. Thus, a SPS film having a bending elastisity of 350 kg/mm 2 or more is obtained. A film having such a high bending elastisity is difficult to coat and adhere a photographic layer on the film. The coating method is described in many patent publications and literatures on pages 3 and 4 of Japanese Patent O.P.I. Publication No. 3-54551/1991. For example, as to surface treatment, corona discharge treatment or a subbing layer coating is detailed. The subbing layer comprises vinylidene chloride, methacrylic acid, acrylic acid, itaconic acid or maleic anhydride. The support thickness is preferably 50 to 250 µm, more preferably 70 to 200 µm. In order to improve anti-curling property, heat treatment is preferably carried out after film formation. The heat treatment is most preferably carried out at a step of the a step from the film formation to emulsion coating, but may be carried out at a step after emulsion coating. The heat treatment is preferably carried out at a temperature of from 45°C to a glass transition point of the film for 1 second to 10 days. The heat treatment time is preferably within one hour in view of productivity. Various photographic additives may be added to light sensitive material as a solution in which the additives are dissolved in water or organic solvents or as a dispersion containing water insoluble additives in fine particle forms in water, gelatin or a hydrophilic or hydrophobic polymer. The colorant, dyes, desensitizing dyes, hydrazines, redox compounds anti-foggants or UV absorber can be dispersed through a conventional disperser. The disperser includes a ball mill, a sand mill, a colloid mill, an ultrasonic disperser and a high speed impeller disperser. The dispersed photographic additives have an average size of 100 µm or less, and ordinarily an average size of 0.02 to 20 µm. The dispersion method includes the following: a method of stirring mechanically with high speed (Japanese Patent O.P.I. Publication No. 58-105141/1983), a method of dissolving additives in an organic solvent while heating and then adding the gelatin or a hydrophilic polymer containing a surfactant or an anti-foam agent to the resulting solution while removing the organic solvent to obtain a dispersion, a method of dissolving additives in a citric acid, acetic acid, sulfuric acid, hydrochloric acid or malic acid solution and then adding the resulting solution to a polymer solution such as a gelatin solution to obtain a dispersion (Japanese Patent O.P.I. Publication No. 50-80119/1975), a method of dissolving additives in an alkaline solution containing sodium hydroxide, sodium bicarbonate, or sodium carbonate and then adding the resulting solution to a polymer solution such as a gelatin solution to obtain a dispersion (Japanese Patent O.P.I. Publication No. 2-15252/1990). For example, hydrazines, which are sparingly soluble in water, can be dissolved according to a method described in Japanese Patent O.P.I. Publication No. 2-3033/1990, and the method applies to other additives. The fixing rate of dyes, sensitizing dyes or restrainers having a carboxyl group is increased in a form of fine crystals employing a chelating capability of the carboxyl group. A sparing soluble salt is preferably formed by adding a calcium or magnesium ion in an amount of 200 to 4000 ppm to a hydrophilic colloid layer. The formation of the sparing soluble salt does not limit the use of other salts. The application of the fine particle dispersion method to sensitizing dyes, colorants, restrainers, accelerators, contrast increasing agents or contrast increasing auxiliary agents is optionally carried out depending on their chemical or physical properties. In the light sensitive material in the invention, two to ten layers are simultaneously coated on a support at a speed of 30 to 1000 m/minute, using a conventional slide hopper or curtain coating method disclosed in US Patent Nos. 3,636,374 and 3,508,947. In order to reduce coating unevenness, a surface tension of a coating solution is preferably lowered or the polymer described above, which has thixotropy reducing viscosity by shearing force, is preferably employed. The light sensitive material in the invention may comprise a cross-over cut layer, an anti-static layer, an anti-halation layer or a back coat layer. The light sensitive material in the invention is packaged in a conventional packaging method. The light sensitive material is poor in resistance to high temperature or humidity, and the storage under severe circumstances shoud be avoided. Generally, the light sensitive material is stored at preferably 5 to 30°C and at a relative humidity of preferably 35 to 60%. The light sensitive material is usually packaged in a polyethylene package to prevent it from moisture. A highly stereoregular polyethylene is prepared employing a metallocene catalyst whereby moisture permeation is minimized. Moisture permeation is also minimized by vacuum evaporation of silica on a polyethylene film to form a 0.1 to 1000 µ silica layer. EXAMPLES The invention will be detailed in the following examples, but is not limited thereto. (Preparation of a support) (Preparation of SPS) In 200 parts by weight of toluene were reacted 100 parts by weight of styrene, 56g of triisobutylaluminium and 234g of pentamethylcyclopentadienyltitanium trimethoxide at 96°C for 8 hours. To the resulting reaction mixture was added a sodium hydroxide methanol solution and the catalyst was decomposed. Thus, the product was obtained and washed three times with methanol. The yield was 34 parts by weight. (Preparation of SPS film) The above obtained SPS was melt-extruded at 330°C from a T die in a layer form, and brought into contact with a chilling drum and solidified to obtain an unoriented film. The SPS was supplied to the chilling drum at three different speeds. The 1054 µm thick unoriented films were heated at 135°C and oriented by 3.1 times in a machine direction, then at 130°C by 3.4 times in a transversal direction and heat set at 250°C. Thus, 130 and 100 µm thick biaxial oriented films were obtained as a support having a bending modulus of elasticity of 450 kg/mm 2 . (Subbing layer coating on the SPS film) Silica was vacuum evaporated on the above obtained SPS film and was coated with an anti-static subbing layer latex solution containing a styrene-glycidylacrylate and tin dioxide fine particles. (Preparation of silver halide emulsion A) Silver bromochloride core grains comprised of 70 mol% of silver chloride and silver bromide, which had an average thickness of 0.05 µm and an average diameter of 0.15 µm, were prepared in a double-jet precipitation method. In the process K 3 RuCl 6 was added in an amount of 8 x 10 -8 mol/mol of silver.

An automatic processor GR-26 (product by Konica Corp.) was modified to be 8 cm 2 /liter of a specific surface area (defined in Japanese Patent O.P.I. Publication Nos. 7-77782, Section 0085) of a developer tank and was employed. The replenishing rate of the developer or fixer replenishing solution was 40 ml per sheet of large full size (610x508 mm). Twenty five tablets were dissolved in water through a dissolving mixer and water was added to make a 1 liter solution, and then was employed for replenishing solutions. Processing condition: Step Temperature Time Developing 35°C 30 sec. Fixing 34°C 20 sec. Washing Ordinary temp. 20 sec. Drying 45°C 20 sec. Line-speed (conveying speed): 984 mm/min. Evaluation The light sensitive material was processed using a fresh solution or running solution as a developer and evaluated with respect to sensitivity, gamma (γ) and dot quality (DQ). As the running solution was used a developer solution after 1000 sheets of the light sensitive material with 508x610 mm size, half of each material being light-exposed with a He-Ne laser, were processed. Sensitivity: Instead of exposure to He-Ne laser, the light sensitive material was exposed through 633 nm interference filter for 6 x 10 -6 sec. and processed in the same manner as above. Sensitometry was made with a densitometer PDA-65 (product by Konica). Sensitivity was shown as a relative value, based on the sensitivity at a density of 2.5 of the light sensitive material processed with the fresh solution being 100. Gamma (γ): Gamma is a gradation, defined as a tangent between densities of 0.1 and 3.0 (alternatively, a slope of a line connecting two points corresponding densities of 0.1 and 3.0). In case of a γ-value of less than 6, the light sensitive material is impractical and even in case of not less than 6 and less than 10, it is insufficient contrast. The γ value of not less than 10 produces a super high contrast image which is sufficient for practical use. The results are shown in Table 2. Dot quality: The photographic material was exposed through a random-patterned halftone screen with 16 µm dot (FM screen) using SG-747RU (product by Dainippon Screen Co.) and processed to form halftone dot image. Medium dots (aimed at 50% dot) were visually evaluated, using 100 times magnifier, with respect to dot quality based on five grades of 5 (the best level) and 4, 3, 2, and 1 (the worst) along with deterioration of the dot quality. Grades of not more than 2 are outside of practical use. The results are shown in Table 2. Black spots The number of black spots in a 2 x 2 mm 2 light sensitive material was counted through a magnifier at a magnification of 40 times. Fifty or more spots can not be put into practical use. The results are shown in Table 2.
