Description: FIELD OF THE INVENTION The present invention relates to a silver halide photographic light-sensitive material containing a hydrazide compound having a specific structure. The invention further relates to novel hydrazide compounds. BACKGROUND OF THE INVENTION In the field of graphic art, in order to obtain good reproduction of a halftone image in continuous gradation or of a line work, an image formation system exhibiting an ultrahigh contrast (particularly having a γ value of 10 or more) photographic property is required. An image formation system of performing development with a processing solution having good storage stability and providing an ultrahigh contrast photographic property is demanded. To cope with it, a system for forming an ultrahigh contrast negative image having a γ value exceeding 10 by processing a surface latent image-type silver halide photographic light-sensitive material having incorporated therein a specific acylhydrazine compound with a developer containing 0.15 mol/ℓ or more of a sulfite preservative and having a pH of 11.0 to 12.3 has been proposed as described in U.S. Patents 4,166,742, 4,168,977, 4,221,857, 4,224,401, 4,243,739, 4,272,606 and 4,311,781. This new image formation system is characterized in that silver iodobromide or silver chloroiodobromide can be used, tough only silver chlorobromide having a high silver chloride content can be used in conventional ultrahigh contrast image formation methods. This system is also characterized in that although conventional lith developers can contain a very small amount of sulfite preservative, the developer can contain a large amount of sulfite preservative, and therefore has relatively good storage stability. However, if the developer has a pH of 11 or more, it is readily air oxidized and unstable and cannot withstand storage or use for a long period of time. Accordingly, attempts have been made to develop a silver halide light-sensitive material containing a hydrazine compound with a developer having a lower pH to form a high contrast image. JP-A-1-179939 (the term "JP-A" as used herein means an "unexamined published Japanese patent application") and JP-A-1-179940 disclose a method for processing a light-sensitive material which contains a nucleation development accelerator having an adsorptive group to a silver halide emulsion grain and a nucleating agent having the same adsorptive group, with a developer having a pH of 11.0 or less. However, since the emulsion used in these inventions is a silver bromide or silver iodobromide emulsion, change in the development progressiveness or in the photographic capabilities due to change in the composition of processing solutions is large and the stability thereof is inadequate. U.S. Patents 4,998,604, 4,994,365 and 4,975,354 disclose a hydrazine compound having an ethylene oxide repeating unit or a hydrazine compound having a pyridinium group. However, in the Examples, the contrast is inadequate and it is difficult in these inventions to achieve high contrast and required Dmax under practical development conditions. Further, the nucleation contrast light-sensitive material using a hydrazine derivative undergoes large change in the photographic properties accompanying the change in the pH of the developer. The pH of the developer greatly changes, more specifically, the pH increases due to oxidation of the developer by air or due to thickening resulting from evaporation of water, or decreases due to absorption of carbon dioxide in air. Accordingly, attempts have been made to reduce dependency of the photographic capabilities upon the pH of the developer. In general, dot-to-dot work light-sensitive materials capable of handling in a bright room are predominating as one of light-sensitive materials for plate-making processing and, in this field, high letter image quality is required so that lean chinese letters of Mincho style can be reproduced. Accordingly, development of nucleating agents having higher activity has been demanded. Particularly, in light-sensitive materials for the bright room which has low sensitivity so as to be handled even in a bright room, the contrast-enhancing effect of the nucleating agents is unwilling to be caused. Therefore, nucleating agents having higher activity have been demanded. To achieve these objects, for example, JP-A-6-148828, JP-A-6-180477 and JP-A-6-194774 disclose highly active hydrazine-base nucleating agents. The nucleating agent having a substituted alkyl group substituted by at least one electron withdrawing group as an acyl group is particularly excellent because extremely high contrast photographic property can be obtained even with a developer having a pH of 11 or less and because change in the photographic capabilities due to fatigue of the developer is small. However, in some cases, the nucleating agent itself is readily oxidized and the storability is in need of much improvement. JP-A-64-86134, JP-A-6-16938 and JP-A-5-197091 disclose compounds having two hydrazino groups incorporated into the molecule. In particular, JP-A-5-197091 discloses some compounds superior in the contrasting capability to conventional acylhydrazine compounds having the same acyl group. However, these are still insufficient in terms of the contrast obtained with a developer having a pH of 11 or less, the stability against fluctuation factor of the processing solutions, and the storability. Accordingly, improvements thereof are needed. On the other hand, a method for obtaining a direct positive image by surface developing an internal latent image-type silver halide photographic emulsion in the presence of a nucleating agent, and a photographic emulsion or light-sensitive material for use in the method are known, for example, in U.S. Patents 2,456,953, 2,497,875, 2,497,876, 2,588,982, 2,592,250, 2,675,318, 3,227,552 and 3,317,322, British Patents 1,011,062, 1,151,363, 1,269,640 and 2,011,391, JP-B-43-29405 (the term "JP-B" as used herein means an "examined Japanese patent publication"), JP-B-49-38164, JP-A-53-16623, JP-A-53-137133, JP-A-54-37732, JP-A-54-40629, JP-A-54-74536, JP-A-54-74729, JP-A-55-52055 and JP-A-55-90940. In the above-described method for obtaining a direct positive image, a nucleating agent may be added to the developer, however, a method of adding the nucleating agent to the photographic emulsion layer or other appropriate layer of the light-sensitive material is more commonly used. As the nucleating agent added to the direct positive silver halide light-sensitive material, hydrazine compounds are most well known and specific examples thereof include those described in Research Disclosure , No. 23510 (November, 1953), ibid. , No. 15162, Vol. 151 (November, 1976), ibid. , No. 17626, Vol. 176 (December, 1978). In general, the hydrazine-base nucleating agent provides large difference between the maximum density (Dmax) and the minimum density (Dmin) and is excellent in the point of discrimination, however, it is deficient in that a high pH (11 or more) is required in the processing, and still in need of improvement in this point. U.S. Patent 5,252,426 discloses hydrazide compounds having a difluoroacetyl group or monofluoroacetyl group as an acyl group. However, these compounds do not have sufficient properties in terms of nucleation contrasting capability. On the other hand, Japanese Patent 3-125134 discloses hydrazide compounds having a difluoroacetyl group. However, these compounds do not exhibit sufficient nucleating capability. EP-A-0736798 (relevant with respect to Art. 54(3) EPC) discloses silver halide photographic materials containing specific hydrazide compounds. U.S. Patent 5,378,578 discloses silver halide photographic materials containing specific compounds having a cationic group.

A third object of the present invention is to provide a direct positive light-sensitive material capable of exhibiting sufficiently high reversibility even with a developer having a low pH and a small addition amount of a hydrazide compound.

The hydrazide compound for use in the present invention (hereinafter occasionally referred to as a "hydrazine-base nucleating agent") may be dissolved in an appropriate water-miscible organic solvent prior to use. Examples of the solvent include alcohols (e.g., methanol, ethanol, propanol, fluorinated alcohol), ketones (e.g., acetone, methyl ethyl ketone), dimethylformamide, dimethylsulfoxide and methyl cellosolve. Alternatively, the hydrazide compound may be used in the form of an emulsion dispersion product obtained by dissolving the compound according to a well known emulsion dispersion method using an oil such as dibutyl phthalate, tricresyl phosphate, glyceryl triacetate or diethylphthalate, or an auxiliary solvent such as ethyl acetate or cyclohexanone, and mechanically forming it into an emulsion dispersion product. Further, powder of the hydrazine derivative may be dispersed in water according to a method known as a solid dispersion method by means of a ball mill, a colloid mill or ultrasonic waves and then used. The hydrazine-base nucleating agent for use in the present invention is preferably used as a fine dispersion (fine crystal grain) solid dispersion. The fine (crystal) grain solid dispersion of the hydrazine-base nucleating agent can be mechanically prepared, if desired, using an appropriate solvent (e.g., water, alcohol) in the presence of a dispersant by a pulverization means (e.g., ball mill, vibration ball mill, planetary ball mill, sand mill, colloid mill, jet mill, roller mill). Also, the hydrazine-base nucleating agent fine (crystal) grain may be prepared using a method of dissolving a hydrazine-base nucleating agent in an appropriate solvent using a surface active agent for dispersion and then adding the solution to a bad solvent of the hydrazine-base nucleating agent to deposit fine crystal, or a method of first dissolving a hydrazine-base nucleating agent by controlling the pH and then finely crystallizing the solution by varying the pH. The thus-obtained hydrazine-base nucleating agent fine (crystal) grains are dispersed in an appropriate binder to prepare a solid dispersion of almost uniform grains, and the solid dispersion is coated on a desired support to provide a layer containing the hydrazine-base nucleating agent fine powder. Alternatively, the layer may be provided by a method of coating a hydrazine-base nucleating agent in the dissociation state as a salt form and overcoating thereon acidic gelatin to achieve dispersion fixation at the time of coating. The above-described binder may be a polymer having an active methylene group, which is described above, or a hydrophilic colloid or synthetic polymer which can be used in a light-sensitive emulsion layer or a light-insensitive layer. The hydrophilic colloid is not particularly limited, however, gelatin is usually preferred. The surface active agent for dispersion may be a known surface active agent and it is preferably an anionic, nonionic or amphoteric surface active agent, more preferably an anionic and/or nonionic surface active agent. The hydrazine-base nucleating agent fine grain in the solid dispersion has an average grain size of from 0.005 to 10 µm, preferably from 0.01 to 1 µm, more preferably from 0.01 to 0.5 µm. The hydrazine nucleating agent of the present invention may be added to any of silver halide emulsion layers and other hydrophilic colloid layers on the silver halide emulsion layer side of the support, however, it is preferably added to the silver halide emulsion layer or a hydrophilic colloid layer adjacent thereto. The nucleating agent of the present invention is preferably added in an amount of from 1×10 -6 to 1×10 -2 mol, more preferably from 1×10 -5 to 1×10 -3 mol, most preferably from 5×10 -5 to 1×10 -3 mol, per mol of silver halide. In the case of processing with the developer having a pH of less than 11 of the present invention, the silver halide photographic light-sensitive material particularly preferably contains a nucleation contrasting accelerator such as an amine derivative, an onium salt, a disulfide derivative or a benzyl alcohol derivative, in a silver halide emulsion layer or other hydrophilic colloid layer. Examples of the nucleation accelerator for use in the present invention include amine derivatives, onium salts, disulfide derivatives and hydroxymethyl derivatives. Examples thereof include: compounds described in JP-A-7-77783, page 48, lines 2 to 37, specifically, Compounds A-1) to A-73) described at pages 49 to 58; compounds represented by (Chem. 21), (Chem. 22) and (Chem. 23) of JP-A-7-84331, specifically, compounds described in pages 6 to 8; and compounds represented by formulae [Na] and [Nb] of JP-A-7-104426, specifically, Compounds Na-1 to Na-22 and Compounds Nb-1 to Nb-12 described at pages 16 to 20. The nucleation accelerator for use in the present invention may be dissolved in an appropriate water-miscible organic solvent such as alcohols (e.g., methanol, ethanol, propanol, fluorinated alcohol), ketones (e.g., acetone, methyl ethyl ketone), dimethylformamide, dimethylsulfoxide and methyl cellosolve, prior to use. Alternatively, the nucleation accelerator may be used in the form of an emulsion dispersion product obtained by dissolving the compound according to a well known emulsion dispersion method using an oil such as dibutyl phthalate, tricresyl phosphate, glyceryl triacetate or diethylphthalate, or an auxiliary solvent such as ethyl acetate or cyclohexanone, and mechanically forming it into an emulsion dispersion product. Further, powder of the nucleation accelerator may be dispersed in water according to a method known as a solid dispersion method by means of a ball mill, a colloid mill or ultrasonic waves and then used. The nucleation accelerator for use in the present invention may be added to any of silver halide emulsion layers and other hydrophilic colloid layers on the silver halide emulsion layer side of the support, however, it is preferably added to the silver halide emulsion layer or a hydrophilic colloid layer adjacent thereto. The nucleation accelerator of the present invention is preferably added in an amount of from 1×10 -6 to 2×10 -2 mol, more preferably from 1×10 -5 to 2×10 -2 mol, most preferably from 2×10 -5 to 1×10 -2 mol, per mol of silver halide. The halogen composition of the silver halide emulsion for use in the present invention is not particularly limited, however, in view of achieving the objects of the present invention more effectively, silver chloride, silver chlorobromide or silver chloroiodobromide having a silver chloride content of 50 mol% or more is preferred. The silver iodide content is preferably less than 5 mol%, more preferably less than 2 mol%. In the present invention, a light-sensitive material suitable for high illuminance exposure such as scanner exposure or a light-sensitive material for photographing line original contains a rhodium compound so as to achieve high contrast and low fog. The rhodium compound for use in the present invention may be a water-soluble rhodium compound. Examples thereof include rhodium(III) halogenide compounds and rhodium complex salts having a halogen, an amine or an oxalate as a ligand, such as hexachlororhodium(III) complex salt, hexabromorhodium(III) complex salt, hexaminerhodium(III) complex salt and trisalaterhodium(III) complex salt. The rhodium compound is dissolved in water or an appropriate solvent prior to use and a method commonly used for stabilizing the rhodium compound solution, namely, a method of adding an aqueous solution of hydrogen halogenide (e.g., hydrochloric acid, bromic acid, hydrofluoric acid) or an alkali halide (e.g., KCl, NaCl, KBr, NaBr), may be used. In place of using a water-soluble rhodium, separate silver halide grains which are previously doped with rhodium may be added and dissolved at the time of preparation of silver halide. The addition amount of the rhodium compound is from 1×10 -8 to 5×10 -6 mol, preferably from 5×10 -8 to 1×10 -6 mol, per mol of silver of the silver halide emulsion. The rhodium compound may be added during production of silver halide emulsion grains or at any appropriate stage before coating of the emulsion, however, it is preferably added at the time of formation of the emulsion to incorporate it into a silver halide grain. The photographic emulsion for use in the present invention can be prepared using a method described in P. Glafkides, Chimie et Physique Photographique , Paul Montel (1967); G.F. Duffin, Photographic Emulsion Chemistry , The Focal Press (1966); and V.L. Zelikman et al, Making and Coating Photographic Emulsion, The Focal Press (1964). A soluble silver salt may be reacted with a soluble halogen salt by any of a single jet method, a double jet method and a combination thereof. A method of forming grains in the presence of excessive silver ions (so-called reverse mixing process) may also be used. As one of the double jet method, a method of maintaining the pAg constant in the liquid phase where silver halide is produced, namely, a so-called controlled double jet method may be used. Further, it is preferred to form grains using a so-called silver halide solvent such as ammonia, thioether or tetra-substituted thiourea, more preferably using a tetra-substituted thiourea compound, and this is described in JP-A-53-82408 and JP-A-55-77737. Preferred examples of the thiourea compound include tetramethyl thiourea and 1,3-dimethyl-2-imidazolidinethione. According to the controlled double jet method or the method of forming grains using a silver halide solvent, a silver halide emulsion comprising regular crystal form grains and having a narrow grain size distribution can be easily prepared, and these methods are a useful means for preparing the silver halide emulsion for use in the present invention. In order to achieve a uniform grain size, it is preferred to rapidly grow grains within the range of not exceeding the critical saturation degree, using a method of changing the addition rate of silver nitrate or alkali halide according to the grain growth rate as described in British Patent 1,535,016, JP-B-48-36890 and JP-B-52-16364, or a method of changing the concentration of the aqueous solution as described in British Patent 4,242,445 and JP-A-55-158124.

Examples of the surface active agent include an anionic surface active agent such as sulfated product and sulfonated product, a polyethylene-base surface active agent, and an amphoteric surface active agent described in JP-A-57-6740. A known defoaming agent may also be added. Examples of the wetting agent include alkanolamines and alkylene glycols. Examples of the fixing accelerator include thiourea derivatives described in JP-B-45-35754, JP-B-58-122535 and JP-B-58-122536, alcohols having a triple bond within a molecule, thioether compounds described in U.S. Patent 4,126,459, meso-ionic compounds described in JP-A-4-229860, and the compounds described in JP-A-2-44355. Examples of the pH buffer include an organic acid such as acetic acid, malic acid, succinic acid, tartaric acid, citric acid, oxalic acid, maleic acid, glycolic acid and adipic acid, and an inorganic buffer such as boric acid, phosphate and sulfite. Among these, preferred are acetic acid, tartaric acid and sulfite. The pH buffer is used here to prevent an increase of the pH value of the fixing agent due to carrying over of the developer, and it is used in an amount of from 0.01 to 1.0 mol/ℓ, preferably approximately from 0.02 to 0.6 mol/ℓ. The fixing solution may also contain the compound described in JP-A-64-4739 as a dye elution accelerator. Examples of the hardening agent in the fixing solution of the present invention include a water-soluble aluminum salt and a chromium salt. Of these, a water-soluble aluminum salt is preferred and examples thereof include aluminum chloride, aluminum sulfate and potassium alum. The addition amount thereof is preferably from 0.01 to 0.2 mol/ℓ, more preferably from 0.03 to 0.08 mol/ℓ. The fixing temperature is generally from about 20°C to about 50°C, preferably from 25 to 45°C, and the fixing time is generally from 5 seconds to 1 minute, preferably from 7 to 50 seconds. The replenishing amount of the fixing solution is generally 600 ml/m 2 or less, preferably 500 ml/m 2 or less, based on the light-sensitive material processed. The light-sensitive material processed through development and fixing is then subjected to water washing or stabilization. The water washing or stabilization is usually performed using water in an amount of 20 ℓ or less per m 2 of the silver halide light-sensitive material and they may be performed at a replenishing amount of 3 ℓ or less (including 0, namely, standing water washing). More specifically, the processing can not only be performed with saved water but also dispense with piping for installation of an automatic developing machine. As a method for reducing the replenishing amount of washing water, a multi-stage countercurrent system (for example, two stages or three stages) has been known. When the multi-stage countercurrent system is applied to the present invention, the light-sensitive material after fixing is processed gradually toward the correct direction, namely, while coming into contact in sequence with processing solutions unstained with the fixing solution, and as a result, water washing can be performed more efficiently. When water washing is performed with a small amount of water, a rinsing tank such as squeeze roller or cross-over roller described in JP-A-63-18350 and JP-A-62-28725 is preferably provided. Alternatively, addition of various oxidizing agents or filter filtration may be combined so as to reduce the pollution load which is a problem to be caused in water washing with a small amount of water. The over-flow solution from the water washing or stabilization bath, which is generated as a result of replenishing water with an antimold means to the water washing or stabilization bath by the method of the present invention, may be partially or wholly used in the processing solution having fixing ability as the previous processing step thereof as described in JP-A-60-235133. Also, a water-soluble surface active agent or a defoaming agent may be added so as to prevent uneven processing due to bubbling which is liable to occur at the time of water washing with a small amount of water, and/or to prevent a processing agent component adhering to the squeeze roller from transferring onto the processed film. Further, a dye adsorbent described in JP-A-63-163456 may be provided in the water washing tank so as to prevent stain due to a dye dissolved out from the light-sensitive material. In some cases, stabilization may be performed following the above-described water washing, and an example thereof is the bath containing the compound described in JP-A-2-201357, JP-A-2-132435, JP-A-1-102553 or JP-A-46-44446 used as a final bath of the light-sensitive material. The stabilizing bath may also contain, if desired, an ammonium compound, a metal compound such as Bi and Al, a fluorescent brightening agent, various chelating agents, a film pH adjusting agent, a hardening agent, a sterilizer, an antimold, an alkanolamine or a surface active agent. Water for use in the water washing or stabilization step may be tap water, but deionized water or water subjected to sterilization with a halogen or ultraviolet bactericidal lamp or various oxidizing agents (e.g., ozone, hydrogen peroxide, chlorate) is preferably used. Further, washing water containing the compound described in JP-A-4-39652 or JP-A-5-241309 may also be used. The temperature and the time in water washing or stabilization are preferably from 0 to 50°C and from 5 seconds to 2 minutes, respectively. The processing solution for use in the present invention is preferably stored in a packaging material having a low oxygen permeability described in JP-A-61-73147. The processing solution for use in the present invention may be formed into powder or a solid. To this effect, the methods described in JP-A-61-259921, JP-A-4-85533 and JP-A-4-16841 are preferably used. In particular, the method described in JP-A-61-259921 is preferred. When the replenishing amount is reduced, the contact area of the processing tank with air is preferably made small so as to prevent evaporation or air oxidation of the solution. The roller transportation-type automatic developing machine is described in U.S. Patents 3,025,779 and 3,545,971. In the present invention, the developing machine of this type is simply referred to as a roller transportation-type processor. The roller transportation-type processor generally composed of four processing steps of development, fixing, water washing and drying. It is most preferred that this four-step system is followed also in the present invention, though use of other steps (for example, stopping) is not excluded. In the four-step system, water washing may be replaced by stabilization. The hydrazine nucleating agent for use in the present invention may also be used in the method for obtaining a direct positive image by surface developing an internal latent image-type silver halide photographic emulsion in the presence of a nucleating agent, or in the photographic emulsion or the light-sensitive material used in such a method (as those described, for examples, in U.S. Patents 2,456,953, 2,497,875, 2,497,876, 2,588,982, 2,592,250, 2,675,318, 3,227,552 and 3,317,322, British Patents 1,011,062, 1,151,363, 1,269,640 and 2,011,391, JP-B-43-29405, JP-B-49-38164, JP-A-53-16623, JP-A-53-137133, JP-A-54-37732, JP-A-54-40629, JP-A-54-74536, JP-A-54-74729, JP-A-55-52055 and JP-A-55-90940). In the above-described method for obtaining a direct positive image, the nucleating agent may be added to the developer, however, it is more commonly added to a photographic emulsion layer or other appropriate layer of a light-sensitive material. Various additives for use in the light-sensitive material of the present invention and the development processing method are not particularly limited, and for example, those described in the following portions may be preferably used.

(Developer A) Sodium hydroxide 1.71 g Diethylenetriaminepentaacetic acid 4 g Potassium carbonate 27.5 g Sodium carbonate 25.5 g Sodium erythorbate 30 g N-Methyl-p-aminophenol 7.5 g KBr 2 g 5-Methylbenzotriazole 0.1 g 1-Phenyl-5-mercaptotetrazole 0.02 g Sodium sulfite 5 g Glacial acetic acid 9 g Water was added to make 1 ℓ and pH was adjusted to 9.7. Developer B and Developer C were prepared by adding an acetic acid to Developer A to adjust the pH to 9.4 and adding sodium hydroxide to Developer A to adjust the pH to 10.0, respectively. Evaluation: (1) Exposure and Development The thus-prepared samples each was exposed to a xenon flash light using a step wedge through an interference filter having a peak at 488 nm for a luminescence time of 10 -5 s and then developed with Developer A, Developer B or Developer C in an automatic developing machine FG-680AG manufactured by Fuji Photo Film Co., Ltd., at 35°C for 20 seconds, followed by fixing, water washing and drying. In the processing, the developer and the fixing solution were replenished in an amount of 100 ml and 150 ml, respectively, per 1 m 2 of the sample. Fixing Solution A having the following formulation was used as the fixing solution. (Fixing Solution A) Ammonium thiosulfate 119.7 g Disodium ethylenediaminetetraacetate dihydrate 0.03 g Sodium thiosulfate pentahydrate 10.9 g Sodium sulfite 25.0 g NaOH (as purity) 12.4 g Glacial acetic acid 29.1 g Tartaric acid 2.92 g Sodium gluconate 1.74 g Aluminum sulfate 8.4 g pH (adjusted by sulfuric acid or sodium hydroxide) 4.8 Water to make 1 ℓ (2) Contrast Contrast obtained upon development with Developer A was expressed as follows. With respect to the index (γ) for showing the contrast of an image, a point giving (fog + density of 0.1) in a characteristic curve and a point giving (fog + density of 3.0) were connected by a straight line and the gradient of the straight line was shown as the γ value. In other words, γ = (3.0-0.1)/[log(exposure amount necessary for giving density of 3.0) - (exposure amount necessary for giving density of 0.1)], and the larger the γ value, the higher the contrast. (3) Photographic Sensitivity The sensitivity was expressed by a reciprocal of the exposure amount necessary for giving a density of 1.5 and the sensitivity of each sample was calculated as a relative value to the sensitivity of a comparative sample taken as 100. The larger the value, the higher the sensitivity. (4) Dependency of Photographic Property on pH of Developer Using the sensitivity Values obtained on development with Developer B and with Developer C, dependency of the sensitivity on the pH of the developer was calculated. pH Dependency of sensitivity (ΔS 1.5 ) = S 1.5 (Developer C) - S 1.5 (Developer B) The smaller the value, the smaller the dependency on pH of the developer, that is, the higher the processing stability. (5) Aging Stability of Light-Sensitive Material Samples stored at a temperature of 60°C and a humidity of 65% for 3 days each was developed with Developer A according to the above-described method, and the sensitivity was measured. Change in the photographic property between the sample obtained above and the sample stored at room temperature and normal humidity for 3 days was determined according to the following formula. Change in sensitivity due to aging (ΔS 1.5 ) = S 1.5 (sample stored at a temperature of 60°C and a humidity of 65% for 3 days) - S 1.5 (sample stored at room temperature and normal humidity for 3 days) The closer to 0 the value, the higher the aging stability of the light-sensitive material. The results obtained are shown in Tables 4-1 and 4-2.

Results: Similarly to Example 2, only when the hydrazide compound used according to the present invention was used as a nucleating agent, a light-sensitive material for helium-neon laser scanner, which provides ultrahigh contrast and exhibits high processing stability with a developer having a low pH and also exhibits excellent aging stability could be obtained. EXAMPLE 4 Preparation of Silver Halide Photographic Light-Sensitive Material: Samples were prepared in the same manner as in Example 2 except for using Compound (S-4) shown below in place of the sensitizing dye used in EM Layer of Example 2. Evaluation: The thus-prepared samples each was exposed to a xenon flash light using a step wedge through an interference filter having a peak at 780 nm for a luminescence time of 10 -6 s. Then, samples each was developed with Developer A described in Example 2 in an automatic developing machine FG-680AG manufactured by Fuji Photo Film Co., Ltd., at 35°C for 20 seconds, and subjected to fixing (same as in Example 2), water washing and drying.
