Description: This invention relates to a method of processing a light-sensitive silver halide color photographic material, and, more particularly, a method of processing a light-sensitive silver halide color photographic material being excellent in the photographic performances for fog and maximum density. In the method of forming dye images by processing light-sensitive silver halide color photographic materials, the dye images are usually formed, after imagewise exposure, by reacting an oxidized p-phenylenediamine type color developing agent with a dye image-forming coupler. In such a method, a color reproduction method according to the subtractive color process is usually used to form dye images of cyan, magenta and yellow respectively corresponding to red, green and blue. Recent years, in the formation of such dye images, it is generally practiced to carry out a high temperature developing and simplify processing steps in order to achieve a shortened developing processing time. In particular, in order to achieve the shortened developing processing time, it becomes very important to increase the developing speed in color development. The developing speed in color development is governed from two approaches. One of them is a light-sensitive silver halide color photographic material, and the other of them is a color developing solution. In the former, the composition of the grains in a silver halide emulsion to be used may give great influence to the developing speed, and, in the latter, the conditions or composition of the color developing solution may give great influence to the developing speed. In the prior art, there have been employed hydroxylamines and sulfites as preservative of the color developing solution. In particular, hydroxylamines are effective as the preservative for p-phenylenediamine type color developing solution. However, there are drawbacks that hydroxylamines are decomposed by oxidization and results in generation of ammonia NH₃. The genarated ammonia NH₃ acts with light-sensitive silver halide photographic material and causes ammonia fog on the light-sensitive material. Particularly, hydroxylamines become to be further decomposable by the presence of heavy metal ions (e.g., Fe³⁺, Cu²⁺, etc.) contained in the color developing solution. Various chelating agents have been inspored and prodiced in order to chelate the heavy metal ions and inhibit their acts. As these chelating agents, there may be exemplified aminopolycarbonic acid, polyphosphoric acid, organic phosphoric acid, etc. However, although these chelating agents are effective for Fe³⁺, they are less effective for Cu²⁺. Also, concentrations of Cu²⁺ and Fe³⁺ in the color developing solution is liable to become higher by the recent tendency to lower the replenishment of the color developing solution economy or shortening the waste solution. Therefore, it is increasingly desired to dissolve the above drawbacks. On the other hand, the light-sensitive silver halide color photographic materials wherein a light-sensitive silver halide emulsion is substantially comprised of silver chloride (hereinafter referred to as light-sensitive silver chloride color photographic materials) can be rapidly developed as compared with conventional light-sensitive color photographic materials comprising a silver halide emulsion containing silver bromides or silver iodides such as silver chlorobromide, silver chloroiodobromide and silver iodobromide, and moreover can be free from accumulation in the color developing solution, of bromide ions or iodide ions which are susceptible to suppress development reactions. Thus, they are very useful as light-sensitive materials for a rapid processing. The present inventors have made various studies by using light-sensitive silver chloride color photographic materials suited for use in the rapid processing, and, as a result, find that the materials have the following disadvantages. That is, as a first instance, the above-mentioned hydroxylamine conventionally used as one of preservatives tends to act as a developing agent for the silver chloride so that the silver development may proceed, to lower color density of color images finally obtained. As a second instance, the above-mentioned sulfite conventionally used as other preservatives tends to act as a dissolving agent for the silver chloride so that the physical development due to a color developing agent may rapidly proceed, to lose the balance between the silver development reaction and the coupling reaction; in other words, the silver development may overly precede and the coupling reaction may delay, whereby the color density is lowered. According to the present inventor's studies, it was also found that fog is liable to appear especially when the solution is contaminated with a heavy metal ion. This fog may largely appear as a whole, and particularly largely has appeared in cyan color used for the purpose of preventing the decrease in color density. This heavy metal ion may raise a problem especially when a large quantity of light-sensitive materials is continuously processed. In a processing method of continuously processing light-sensitive silver halide color photographic materials by use of an automatic processor and the like, it is also necessary to take a measure for keeping components in a color developing solution in the range of predetermined concentration in order to prevent the change in the development finishing performance due to the change in the concentration of the components. As such a measure, there has been usually used a method in which a replenishing solution is supplied to replenish short components and dilute unnecessary increased components. Supplying such a replenishing solution may bring about an overflow in a large quantity, which must be abandoned, throwing a great problem from an economical viewpoint and an environmental viewpoint. For this reason, in recent years, the so-called concentrated low replenishing system wherein the replenishing solution is made to have a higher concentration and supplied in a small quantity has been extensively used in order to decrease the above overflow solution. In such a system, however, heavy metal ions are liable to be accumulated, thereby raising the above problem of fog due to heavy metal ions. It has thus been sought after to solve these problems. SUMMARY OF THE INVENTION Research Disclosure number 18844 discloses a method of packaging photographic color developers. The hydroxylamine containing part of a kit concentrate is stabilized against decomposition by the inclusion of polyhydroxy aromatic compounds. EP-A-0 159 912 and EP-A-0 156 377 describe color photographic materials containing cyan couplers of the type hereinafter designated (C-I), (C-II) and (C-III). According to the present invention there is provided a method of processing an imagewise exposed light-sensitive silver halide color photographic material having at least one silver halide emulsion layer comprising the step of color developing by the use of a color developer solution containing an aromatic primary amine developing agent and an N,N-dialkylhydroxylamine or a water soluble salt thereof having the General Formula (I) below: in which R₁ and R₂ each represent an alkyl group having up to 3 carbon atoms, and at least one dihydroxy compound having one of the General Formulae (II) and (III) below: in which R₁, R₂, R₃, R₄, R₉ and R₁₀ each represent a hydrogen atom, a halogen atom, a sulfonic acid group, an alkyl group having up to 7 carbon atoms, a group -OR₅, a group -COOR₆, a phenyl group, or a group in which R₅, R₆, R₇ and R₈ each represent a hydrogen atom or an alkyl group having up to 18 carbon atoms, characterized in that the light-sensitive silver halide emulsion layer contains silver halide grains comprising at least 80 mol % of silver chloride. DESCRIPTION OF THE PREFERRED EMBODIMENTS In General Formula (I), R₁ and R₂ each represent an alkyl group having up to 3 carbon atoms, and the alkyl group having up to 3 carbon atoms represented by R₁ and R₂ may be the same or different, including, for example, a methyl group, an ethyl group, an n-propyl group or an iso-propyl group. R₁ and R₂ are preferably both an ethyl group. Specific examples of the compound represented by General Formula (I) are shown below, but the invention is by no means limited to these. These compounds are usually used in the form of salts such as hydrochloride, sulfate, p-toluenesulfonate, oxalate, phosphate and acetate. Concentration of the compound (I) in the color developing solution may be approximately the same as the concentration of the hydroxylamine usually used as a preservative, and it may be used preferably in concentration of 0.1 g/l to 50 g/l, more preferably 0.5 g/l to 30 g/l . Of the compound represented by General Formula (I), N,N-diethylhydroxylamine, for example, is known to be used as a preservative of a black and white developing agent in a color developing solution to which a black and white developing agent is added. It is known that usually the black and white developing agent, i.e., hydroquinone, hydroquinonemonosulfonic acid, phenidone, p-aminophenol, is relatively stable when used as the black and white developing agent in the black and white developing solution, and can be sufficiently preserved by using sulfite as a preservative, but, once it is added to a color developing solution, there takes place a cross oxidation reaction with a color developing agent, resulting in its very poor storage stability. Hydroxylamine is hardly effective for the preservation of the black and white developing agent added to such a color developing solution. As an example in which N,N-diethylhydroxylamine is used as a preservative of the black and white developing agent added to a color developing solution, it is known to use it together with phenidone in the so-called external color process, which is a process by which a light-sensitive color photographic material is developed according to a reversal process by using a color developing solution containing a coupler. In such an instance, a role of the phenidone is to increase the developing speed of the light-sensitive material of external system having poor developing performance and to increase the density of a dye image. In, for example, a magenta color developing solution containing such phenidone, N,N-diethylhydroxylamine is also known to adversely affect the preservativity of the color developing solution of external system as it destroys the coupler (see Japanese Patent Publication No. 22198/1970). As other example in which a compound such as N,N-diethylhydroxylamine or the like is used as a preservative of the black and white developing agent in a color developing solution, reference can be made to a technique by which a phenidone derivative added to a color developing agent is preserved (see Japanese Unexamined Patent Publication No. 32035/1978) or a technique by which a phenidone derivative is similarly preserved together with hydroquinones (see Japanese Unexamined Patent Publication No. 153437/1977). As mentioned above, the compound has been conventionally known to be used as a preservative of the black and white developing agent added to a color developing solution, but has not been known as a preservative of a color developing agent in an ordinary color developing solution. Thus, a part of the compound has been already known as a preservative of the black and white developing agent added to a color developing solution. However, according to this invention, not only the compound (I) can effectively act as a preservative of an ordinary color developing solution, but also the color density may not be lowered even when used in combination with a particular coupler shown below, and, by using the compound in combination with a chelating agent or agents represented by General Formula (II) and/or General Formula (III), generation of fog due to the contamination with heavy metals can be desirably prevented, and further, there can be obtained a developing solution having excellent stability without fall of pH and formation of tar. These are surprising effects that can not be expected at all. One of the conditions for the color developing solution used in this invention is to contain the sulfite in concentration of 2 x 10⁻² mole or less, preferably 4 x 10⁻³ or less, per 1 liter of the color developing solution. In this invention, it is preferable to lower the concentration of the above sulfite below a constant value, because it can further inhibit the lowering of the color density of color image and accomplish the effect of this invention more effectively. The sulfite used in this invention may include sodium sulfite, potassium sulfite, sodium bisulfite, potassium bisulfite, etc. The color developing agent used in this invention contains at least one compound selected from the compound represented by General Formula (II) and the compound represented by General Formula (III) (hereinafter referred to as the chelating agent of this invention). In General formulas (II) and (III), R₁, R₂, R₃, R₄, R₉ and R₁₀ each represent a hydrogen atom, a halogen atom, a sulfonic acid group, an alkyl group having 1 to 7 carbon atoms, -OR₅, -COOR₆, or a phenyl group, R₅, R₆, R₇ and R₈ each represent a hydrogen atom or an alkyl group having 1 to 18 carbon atoms. The alkyl group represented by R₁, R₂, R₃, R₄, R₉ and R₁₀ may be substituted or unsubstituted and may include, for example, a methyl group, an ethyl group, an iso-propyl group, an n-propyl group, a t-butyl group, a n-butyl group, a hydroxymethyl group, a hydroxyethyl group, a methylcarboxylic acid group, a benzyl group, etc. The alkyl group represented by R₅, R₆, R₇ and R₈ may also include those same as the above, and may additionally include an octyl group. The phenyl group represented by R₁, R₂, R₃, R₄, R₉ and R₁₀ may include a phenyl group, a 2-hydroxyphenyl group, a 4-aminophenyl group, etc. Typical examples of the chelating agent of this invention are shown below, but by no means limited to these. (II-1) 4-Isopropyl-1,2-dihydroxybenzene (II-2) 1,2-Dihydroxybenzene-3,5-disulfonic acid (II-3) 1,2,3-Trihydroxybenzene-5-carboxylic acid (II-4) 1,2,3-Trihydroxybenzene-5-carboxymethyl ester (II-5) 1,2,3-Trihydroxybenzene-5-carboxy-n-butyl ester (II-6) 5-t-Butyl-1,2,3-trihydroxybenzene (II-7) 1,2-Dihydroxybenzene-3,5,6-trisulfonic acid (II-8) 1,2-Dihydroxybenzene-6-chloro-3,5-disulfonic acid (II-9) 1,2-Dihydroxybenzene-3,4,5,6-tetrasulfonic acid (III-1) 2,3-Dihydroxynaphthalene-6-sulfonic acid (III-2) 2,3,8-Trihydroxynaphthalene-6-sulfonic acid (III-3) 2,3-Dihydroxynaphthalene-6-carboxylic acid (III-4) 2,3-Dihydroxy-8-isopropyl-naphthalene (III-5) 2,3-Dihydroxy-8-chloro-naphthalene-6-sulfonic acid Among the above compounds, particularly preferably used in this invention is 1,2-dibydroxybenzene-3,5-disulfonic acid, which may be also used as alkali salts such as a sodium salt and a potassium salt. In this invention, the above chelating agent represented by General Formula (II) or (III) of this invention may be used in the range of 5 mg to 20 g, preferably added in an amount of 10 mg to 10 g, more preferably 20 mg to 3 g, per 1 liter of the developing solution, to obtain good results. The chelating agent may be used alone or may be used in combination. There may be further used, in combination, other chelating agents such as aminopolyphosphonic acids such as aminotri (methylenephosphonic acid) and ethylenediaminetetraphosphoric acid, oxycarboxylic acids such as citric acid and gluconic acid, phosphonocarboxylic acids such as 2-phosphonobutane-1,2,4-tricarboxylic acid, polyphosphoric acids such as tripolyphosphoric acid and hexametaphosphoric acid. The color developing agent used in the color developing solution of this invention may preferably include p-phenylenediamine type compounds having a water soluble group. The p-phenylenediamine type compounds having a water soluble group have advantages not only that they may produce no stain on light-sensitive materials and hardly cause a rash on skin even if the skin was smeared with them, as compared with p-phenylenediamine type compounds having no water soluble group such as N,N-diethyl-p-phenylenediamine or the like, but also that they can afford to effectively achieve the objects of this invention by using them particularly in combination with the compound represented by General Formula (I) in this invention. The above water soluble group may be such that at least one water soluble group is possessed on an amino group or benzene ring of the p-phenylenediamine type compounds. Specific water soluble group may preferably include -(CH₂) n -CH₂OH, -(CH₂) m NHSO₂-(CH₂) n -CH₃, -(CH₂) m O-(CH₂) n -CH₃, -(CH₂CH₂O) n C m H 2m+1 (m and n each represent an integer of 0 or more), a -COOH group, a -SO₃H group. Specific exemplary compounds of the color developing agent preferably used in this invention are shown below. Exemplary color developing agents Among the color developing agents exemplified in the above, those which can be preferably used in this invention as being free from generation of fog are compounds shown as exemplary Nos. (A-1), (A-2), (A-3), (A-4), (A-6), (A-7) and (A-15), and particularly preferable compound is No. (A-1). The above color developing agents are generally used in the form of salts such as hydrochloride, sulfate, p-toluenesulfonate, etc. The color developing agent having a water soluble group, used in this invention, may be used preferably in the range of 1 x 10⁻² to 2 x 10⁻¹ mole per 1 liter of the color developing solution, more preferably from a viewpoint of the rapid processing, in the range of 1.5 x 10⁻² to 2 x 10⁻¹ mole per 1 liter of the color developing solution. The color developing solution of this invention may contain the following developing solution components, in addition to the above component. As alkali agents other than the above carbonates, sodium hydroxide, potassium hydroxide, silicate, sodium metaborate, potassium metaborate, trisodium phosphate, tripotassium phosphate, borax, etc. may be used alone or in combination so far as the above effects of this invention, namely, the effect of no occurrence of precipitation and the effect of making the pH stable can be maintained. If necessary for the preparation of the solution, or for the purpose of increasing inteneity of ions, there can be used a variety of salts such as disodium hydrogenphosphate, dipotassium hydrogenphosphate, sodium bicarbonate, potassium bicarbonate and borate. If necessary, an inorganic or organic antifoggant may be also added. If necessary, a development accelerator can be also used. Such a developing accelerator may include every kind of pyridinium compounds as typified by those disclosed in U.S. Patents No. 2,648,604 and No. 3,671,247, and Japanese Patent Publication No. 9503/1969 and other cationic compounds, cationic dyes such as phenosafranine, neutral salts such as thallium nitrate, polyethylene glycol or derivatives thereof disclosed in U.S. Patents No. 2,533,990, No. 2,531,832, No. 2,950,970 and No. 2,577,127 and Japanese Patent Publication No. 9504/1969, nonionic compounds such as polythioethers, organic solvents disclosed in Japanese Patent Publication No. 9509/1969, or organic amines, ethanolamine, ethylenediamine, diethanolamine, triethanolamine, etc. It may also include benzyl alcohol disclosed in U.S. Patent No. 2,304,925, phenethyl alcohol, and besides these, acetylene glycol, methyl ethyl ketone, cyclohexane, thioethers, pyridine, ammonia, hydrazine, amines, etc. In the above, the bad soluble organic solvent particularly typified by benzyl alcohol tends to cause appearance of tar after use of the color developing solution for a long period of time, particularly during the running processing according to a low replenishing system. Appearance of such tar, when adhered on a paper light-sensitive material to be processed, may even bring about such a serious trouble that a commercial value of the product is extremely damaged. Also, since the bad solvent organic solvent has poor solvency to water, there is not only a cumbersomeness that a stirring instrument is needed to prepare the color developing solution itself, but also a limit to the development accelerating effect due to the badness of its solvency rate even with use of such a stirring instrument. The bad solvent organic solvent does further have problems such that it has a great value for the burden to environmental pollution such as biochemical oxygen demand (BOD), and cannot be abandoned in sewerages, rivers or the like, so that much labor and cost are needed for waste liquor disposal. Accordingly, it is preferably used in a decreased amount, or not used. Further, in the color developing solution of this invention, if necessary, ethylene glycol, methyl cellosolve, methanol, acetone, dimethylformamide, β-cyclodextrin and other compounds disclosed in Japanese Paent Publications No. 33378/1972 and No. 9509/1969 can be used as an organic solvent for increasing the dissolving degree of a developing agent. An auxiliary developing agent can be also used together with the developing agent. Such an auxiliary developing agent is known to include, for example, N-methyl-p-aminophenol hexasulfate (Metol), phenidone, N,N′-diethyl-p-aminophenol hydrochloride, N,N,N′N′-tetramethyl-p-phenylenediamine hydrochloride, and may be added usually in an amount of 0.01 g to 1.0 g/lit. Besides these, if necessary, there can be further added competing couplers, fogging agents, colored couplers, development restrainer-releasing type couplers (the so-called DIR couplers) or development restrainer-releasing compounds. Still further, besides, various additives such as anti-stain agents, sludge preventive agents and interlayer effect accelerators can be used. The respective components of the above color developing agent can be prepared by successively adding them to a given amount of water, followed by stirring. In this occasion, a component having poor solvency to water may be added by mixing it with the above organic solvent such as triethanolamine. More generally, a mixture of a plurality of components that can be stably present together with each other, prepared in the form of a concentrated aqueous solution or a solid in a small container, may be added in water and stirred to obtain a solution as the color developing solution of this invention. In this invention, the above color developing agent can be used in a desired pH range, but, from a viewpoint of rapid processing, preferably in the range of pH 9.5 to 13.0, more preferably pH 9.8 to 13.0. In this invention, the color developing processing temperature may be not lower than 30°C and not higher than 50°C, within which the higher it is, the more preferably it becomes possible to carry out rapid processing in a short time, but, from a viewpoint of image preservation stability, the temperature should not be so high. Thus, the processing is preferably carried out at not lower than 33°C and not higher than 45°C. In general, the color developing is conventionally carried out in about 3 minutes and 30 seconds, but, in the present invention, it can be carried out in 2 minutes or less, or can be also carried out in the range of 30 seconds to 1 minute and 30 seconds. This invention can be applied in any system if it is a system using the color developing solution containing the compound represented by the above General Formula (I) and at least one compound selected from the compound represented by the above General Formula (II) and the compound represented by the above General Formula (III). For example, there can be used a monobath processing system, as well as other various types of processing systems such as a spray system in which a processing solution is formed into a spray, a web system utilizing the contact with a carrier impregnated with a processing solution, or a developing system using a viscous processing solution. However, the processing step should substantially comprise the steps of color developing, bleach-fixing and washing or stabilizing that can be substituted with the washing. The bleach-fixing step may be constituted separately of a bleaching step and a fixing step, or may comprise a bleach-fixing bath carrying out the bleaching and fixing in a bath. Bleaching agents that can be used in the bleach-fixing solution used in this invention are metal complex salts of organic acids. The complex salts are compounds formed by coordination of a metal ion such as iron, cobalt, copper, etc. with an organic acid such as aminopolycarboxylic acid or oxalic acid and citric acid. Most preferable organic acid used for the formation of metal complex salts may include polycarboxylic acid. These polycarboxylic acid and aminopolycarboxylic acid may be alkali metal salts, ammonium salts or water soluble amine salts. Specific examples of these may include the following: [1] Ethylenediaminetetraacetic acid [2] Diethylenetriaminepentaacetic acid [3] Ethylenediamine-N-(β-oxyethyl)-N,N′,N′-triacetic acid [4] Propoylenediaminetetraacetic acid [5] Nitrilotriacetic acid [6] Cyclohexanediaminetetraacetic acid [7] Iminodiacetic acid [8] Dihydroxyethylglycinecitric acid (or tartaric acid) [9] Ethyl ether diaminetetraacetic acid [10] Glycol ether diaminetetraacetic acid [11] Ethylenediaminetetrapropionic acid [12] Phenylenediaminetetraacetic acid [13] Ethylenediaminetetraacetic acid disodium salt [14] Ethylenediaminetetraacetic acid tetra(trimethylammonium)salt [15] Ethylenediaminetetraacetic acid tetrasodium salt [16] Diethylenetriaminepentaacetic acid pentasodium salt [17] Ethylenediamine-N-(β-oxyethyl)-N,N′,N′-triacetic acid sodium salt [18] Propylenediaminetetraacetic acid sodium salt [19] Nitrilotriacetic acid sodium salt [20] Cyclohexanediaminetetraacetic acid sodium salt These bleaching agent may be used preferably in an amount of 5 to 450 g/lit., more preferably 20 to 250 g/lit. The bleacb-fixing solution may contain a silver halide fixing agent in addition to the bleaching agent mentioned above, and, if necessary, a solution of the composition containing sulfite as a preservative may be used. There can be also used a bleach-fixing solution of the composition to which an ethylenediaminetetraacetic acid iron (III) complex salt bleaching agent and a halide such as ammonium bromide other than the above silver halide fixing agent are added in a small amount, or, on the contrary, a bleach-fixing solution of the composition to which a silver halide such as ammonium bromide is added in a large amount, or a special bleach-fixing solution of the composition comprising a combination of an ethylenediaminetetraacetic acid iron (III) complex salt bleaching agent and a large amount of silver halide such as ammonium bromide. The above halide that can be used may include, besides ammonium bromide, hydrochloric acid, hydrobromic acid, lithium bromide, sodium bromide, potassium bromide, sodium iodide, potassium iodide, ammonium iodide, etc. The silver halide fixing agent contained in the bleach-fixing solution may typically include the compounds capable of forming a water soluble complex salt by reacting with a silver halide, as used in ordinary fixing processing, for example, thiosulfates such as potassium thiosulfate, sodium thiosulfate and ammonium thiosulfate; thiocyanates such as potassium thiocyanate, sodium thiocyanate and ammonium thiocyanate; thioureas; thioethers; etc. These fixing agents may be used in an amount of 5 g/lit. or more and in the range of the amount that can be dissolved, and, in general, may be used in an amount of 70 g to 250 g/lit. The bleach-fixing solution may contain, solely or in combination, a variety of pH buffering agents such as boric acid, borax, sodium hydroxide, potassium hydroxide, sodium carbonate, potassium carbonate, sodium bicarbonate, potassium bicarbonate, acetic acid, sodium acetate and ammonium hydroxide. It may also contain various brightening agents, anti-foaming agents or surface active agents. It may further appropriately contain preservatives such as bisulfite addition products of hydroxylamine, hydrazine or an aldehyde compound, organic chelating agents such as aminopolycarboxylic acid or stabilizers such as nitroalcohol and nitrate, and organic solvents such as methanol, dimethylsulfonamide and dimethylsulfoxide. To the bleach-fixing solution used in this invention, various bleach accelerating agents may be added, disclosed in Japanese Unexamined Patent Publication No. 280/1971, Japanese Patent Publications No. 8506/1970, and No. 556/1971, Belgian Patent No. 770,910, Japanese Patent Publications No. 8836/1970 and No. 9854/1978, Japanese Unexamined Patent Publications No. 71634/1979 and No. 42349/1974, etc. can be added. The bleach-fixing solution may be used at the pH of 4.0 or more, but, in general, at the pH of not less than 5.0 and not more than 9.5, more preferably at the pH of not less than 6.0 and not more than 8.5, and still more preferably at the pH of not less than 6.5 and not more than 8.5 to carry out the processing. The processing temperature to be used may be a temperature of not less than 3°C, preferably not less than 5°C, lower than the processing temperature in a color developing tank, and, desirably, a temperature of not less than 55°C while suppressing the evaporation or the like. In this invention, the above color developing and bleach-fixing steps are followed by washing or a process by use of washing solution substitute, so-called washing substitutive stabilizing processing, in place of the washing. The process of the water washing substitute according to this invention is a process carried out in place of a water washing step following on a fixing step or a bleach-fixing step. Conventional water washing process is a process for washing away, by washing with water, a processing solution of a previous bath contained in structural layers of the light-sensitive material, specifically a large amount of thiosulfates, chemicals and silver complex salts contained in a fixing solution or a bleach-fixing soluiton, chemicals contained in a color developing solution and the like. This process includes, for example, a method in which a large amount of flowing water is flown on the surface of a light-sensitive material in a water washing bath to remove the processing solution of the provious bath, a substituting water washing method in which a light-sensitive material is dipped in a constant amount of water and the water is changed by fresh water after constant time passed, etc. Although, this water washing process is usually carried out only by use of water, it may be conducted after dipping the light-sensitive material in a bath containing salts such as sodium sulfite, etc. for several minutes in order to accelerate the processing speed. In any event, the water processing is carried out by using water. Therefore, a large amount of water for washing is required for preventing any troubles such as drying of the light-sensitive material, dirt, discoloration and fading of images, etc. during storage caused by chemicals such as thiosulfate remained in the light-sensitive material. Further, since equipments for discharging the water is required after the water washing process, such process is not good spatially and economically. The process by use of the washing solution substitute dissolved such problems. The processing solution used for the process is not merely water, but a solution containing an antimildew, antiseptic, disinfection means, further optionally, a chelating agent having the chelating stabilization degree against ferric ion of 8 or more, ammonia compounds, organic acid salts, pH adjusting agents, surfactants, sulfites, brightening agents, etc. In the conventional water washing process, the compounds adhered or permeated in the light-sensitive material such as thiosulfates, etc. were washed away by replenishing water in about 5 lit. to 150 lit. per 1 m² of the light-sensitive material. On the other hand, according to the process of washing solution substitute of this invention, such compounds adhered or permeated in the light-sensitive material is washed away by a replenished amount of about 0.01 lit. to 2.5 lit. per 1 m² of the light-sensitive material. Further, since the process of this invnetion can be made by use of very little replenished amount as compared with the convnetional processes, feeding- and discharging-piping equipments of water to an automatic processing machine which has been required in the conventional water washing process became not to be necessarily required, and thus miniturization of the equipment is accomplished. The processing by use of washing solution substitute applicable in this invention will be described below. The pH of the washing soluiton substitute may range between 5.5 and 10.0. The pH-adjusting agents that can be contained in the washing solution substitute applicable in this invention may be any of those of alkali agents or acid agents generally known in the art. The processing by use of the washing solution substitute (or the stabilizing processing or steps) may be carried out at a temperature ranging between 15°C and 60°C, preferably 20°C and 45°C. The processing time as short as possible is also more preferable from a viewpoint of the rapid processing, but, in general, may be in the range of 20 seconds to 10 minutes, most preferably 1 minute to 3 minutes. In the case of the processing of washing solution substitute using multiple tanks, it is also preferable to carry out the processing in a shorter time in anterior tanks and in a longer time in posterior tanks. It is particularly preferable to successively carry out the processing in such a time that is 20 % to 50 % longer than the processing time in an anterior tank. No washing is required at all after the processing of washing solution substitute applicable in this invention, but rinsing with use of small amount of water in a very short time or surface washing may be optionally carried out if necessary. The processing of washing solution substitute (or the stabilizing step) applicable in this invention may be supplied, in the case of a multiple tank counter current system, in such a manner that the solution is supplied to a posterior tank and overflowed from an anterior tank. As a matter of course, the processing may be carried out in a single tank. As the method of adding above compounds, various methods are available, including a method in which the compounds are added to a stabilizing tank in the form of a concentrated solution, or a method in which the above compounds and other additives are added to the washing soluiton substitute supplied to a stabilizing tank, and the resulting solution is used as a supplying solution for replenishing the washing solution substitute. Any of these method may be used for the addition. Thus, in this invention, the processing by the washing soluiton substitute also refers to the processing for stabilizing, wherein stabilizing processing is carried out immediately after processing by a processing solution having bleach-fixing ability without substantially carrying out washing with water, and the processing solution used in such stabilizing solution is called the washing solution substitute, and the processing tank is called a washing solution substitute tank (or a stabilizing bath or a stabilizing tank). The stabilizing tank in the stabilizing processing applicable in this invention may preferably comprise 1 to 5 tanks, particularly preferably 1 to 3 tanks, and not more than 9 tanks at most. According to the preferred embodiment of the present invention, the method of processing the light-sensitive silver halide color photographic material of this invention is to process a light-sensitive silver halide color photographic material having a silver halide emulsion layer containing silver halide grains substantially comprised of silver chloride, by using the aforesaid color developing solution used in this invention, i.e., the color developing solution containing as preservatives the compounds of this invention, the compound (I). The silver halide grains used in the light-sensitive silver halide color photographic material applied in this invention are preferably substantially comprised of silver chloride. In this invention the terms "silver halide grains substantially comprised of silver chloride" are meant to be silver halide grains containing at least not less than 80 mole %, preferably not less than 90 mole %, and more preferably not less than 95 mole %, of silver chloride. The silver halide emulsion containing the above silver halide grains substantially comprised of silver chloride may contain, besides silver chloride, silver bromide and/or silver iodide as the silver halide composition. In such a case, silver bromide may be contained in an amount of 20 mole % or less, preferably 10 mole % or less, more preferably 5 mole % or less. When silver iodide is present, it may be contained in an amount of 1 mole % or less, preferably 0.5 mole % or less. Such silver halide grains of this invention, substantially comprised of silver chloride may be contained preferably to account for 80 % or more, more preferably 100 %, in % by weight, of total silver halide grains in the silver halide emulsion layers which contain the silver halide grains. Crystals of the silver halide grains used in this invention may be of regular crystals, twin crystals or others, and there can be used those having any ratio of [ 100] face to [ 111] face. The crystal structure of these silver halide grains may be uniform through inside to outside, or may be of layered structure comprising an inside and outside of different nature (a core/shell type). These silver halide grains may be also of the type such that a latent image is chiefly formed on the surface, or of the type wherein it is formed in the inside of a grain. Tabular silver halide grains (see Japanese Unexamined Patent Publication No. 113934/1983 and Japanese Patent Application No. 170070/1984) can be also used. The silver halide grains used in this invention may be obtained by any preparation methods including an acidic method, a neutral method and an ammoniacal method. Alternatively, seed grains may be prepared according to an acidic method, which are allowed to grow according to an ammoniacal method that can achieve higher growth rate, until they grow to have given size. When growing the silver halide grains, it is preferable to control the pH and pAg in a reaction vessel, and pouring and mixing silver ions and halide ions successively and simultaneously in the amount corresponding to the growth rate of silver halide grains as disclosed, for example, in Japanese Unexamined Patent Publication No. 48521/1979. The silver halide grains according to this invention are preferably prepared in the above-mentioned manner. In the present specification, a composition containing such silver halide grains are referred to as a silver halide emulsion. The silver halide emulsion may be chemically sensitized by using active gelatin; sulfur sensitizing agents, for example, sulfur sensitizing agents such as allylthiocarbamide, thiourea and cystine; selenium sensitizing agents; reduction sensitizing agents, for example, stunnous salts, thiourea dioxide, polyamine, etc.; noble metal sensitizing agents, for example, gold sensitizing agents, specifically including sensitizing agents such as potassium aurothiocyanate, potassium chloroaurate and 2-aurothio-3-methylbenzothiazolium chloride, or sensitizing agents having a water soluble group, for example, ruthenium, palladium, platinum, rhodium, iridium, etc., specifically including ammonium chloropalladate, potassium chloroplatinate and sodium chloropalladate (Some of their act as a sensitizing agent or a fog-suppressing agent depends on whether they are in a large amount or a small amount.), etc., which may be used alone or in appropriate combination (for example, combination of a gold sensitizing agent with a sulfur sensitizing agent, combination of a gold sensitizing agent with a selenium sensitizing agent, etc.). The silver halide emulsion according to this invention may be subjected to chemical ripening by adding a sulfur-containing compound, and, before such chemical ripening, during the ripening, or after the ripening, at least one of hydroxytetrazaindenes and at least one of nitrogen-containing heterocyclic compounds having a mercapto group may be contained. The silver halide used in this invention may be optically sensitized by adding a suitable sensitizing dye in amount of 5 x 10⁻⁸ mole to 3 x 10⁻³ mole per mole of silver halide so that sensitivities to respectively desired light-sensitive wavelength regions can be imparted thereto.

Synthesis of Exemplary compound C - 101 [(1) - a] Synthesis of 2-nitro-4,6-dichloro-5-ethylphenol In 150 ml of glacial acetic acid were dissolved 33 g of 2-nitro-5-ethylphenol, 0.6 g of iodine and 1.5 g of ferric chloride. To the mixture was added dropwise 75 ml of sulfuryl chloride at 40°C over 3 hours. After completion of the dropwise addition of the sulfuryl chloride, precipitates formed during the dropwise addition are reacted and dissolved by heating under reflux. It took about 2 hours for the heating under reflux. Then, the reaction mixture was poured into water and the formed crystals were purified by recrystallization from methanol. Confirmation of (1) - a was carried out by the nuclear magnetic resonance spectrum and the elemental analysis. [(1) - b] Synthesis of 2-amino-4,6-dichloro-5-ethylphenol In 300 ml of alcohol was dissolved 21.2 g of the above compound [(1) - a], and to the solution was added a catalytic amount of Raney nickel and hydrogen was passed therethrough under ambient pressure until no hydrogen absorption was observed. After the completion of the reaction, the Raney nickel was removed and the alcobol was distilled out under reduced pressure. The resulting residue was employed in the next acylation step without purification.

Such a DIR compound may typically include DIR couplers wherein a group capable of forming a compound having a development restraining action has been introduced to a coupler active site when eliminated from the active site, which are disclosed, for example, in British Patent No. 935,454, U.S. Patents No. 3,227,554, No. 4,095,984 and No. 4,149,886, etc. The above DIR couplers have a property that a coupler mother nucleus may form a dye and, on the other hand, a developing restrainer is released when coupled with an oxidized product of a color developing agent. In this invention, also included is such a compound capable of releasing a development restrainer but not forming any dye when coupled with an oxidized product of a color developing agent, as disclosed in U.S. Patents No. 3,652,345, No. 3,928,041, No. 3,958,993, No. 3,961,959 and No. 4,052,213, Japanese Unexamined Patent Publications No. 110529/1978, No. 13333/1979 and No. 161237/1980, etc. Still also included in this invention is the so-called timing DIR compound which is a compound such that a mother nucleus may form a dye or colorless compound when reacted with an oxidized product of a color developing agent, and on the other hand, an eliminated timing group may release a development restrainer through the intramolecular nucleophilic substitutive reaction or elimination reaction. As disclosed in Japanese Unexamined Patent Publication Nos. 145135/1979, 114946/1979 and 154234/1982. There may be also included a timing DIR compound wherein the timing group as mentioned above has been attached onto a coupler mother nucleus capable of forming a perfectly diffusing dye when reacted with an oxidized product of a color developing agent, as disclosed in Japanese Unexamined Patent Publications No 160954/1983 and No. 162949/1983. The DIR compound contained in the light-sensitive material may be used preferably in an amount ranging between 1 x 10⁻⁴ mole to 10 x 10⁻¹ mole per mole of silver. The light-sensitive silver halide color photographic material used in this invention may additionally contain a variety of additives for photography. For example, there may be used antifoggants, stabilizers, ultraviolet absorbent, color stain preventive agents, brightening agents, color image-fading preventive agents, antistatic agents, hardening agents, surface active agents, plasticizers, wetting agents, etc. which are disclosed in Research Disclosure No. 17643. In the light-sensitive silver halide color photographic material of this invention, hydrophilic colloid used for preparing an emulsion may include any of proteins such as gelatin, derived gelatin, graft polymers of gelatin with other macromolecules, albumin and casein; cellulose derivatives such as hydroxyetbyl cellulose derivatives and carboxymethyl cellulose; starch derivatives; synthetic bydrophilic macromolecules of homopolymers or copolymers such as polyvinyl alcohol, polyvinyl imidazole and polyacrylamide; etc. Supports for the light-sensitive silver halide color photographic material used in this invention may include, for example, baryta paper, polyethylene-coated paper, polypropylene synthetic paper, transparent supports provided with a reflection layer in combination, or using a reflecting body in combination, for example, glass plates, polyester films of cellulose acetate, cellulose nitrate or polyethylene terephthalate, polyamide films, polycarbonate films, polystyrene films, etc., and may also include other conventional transparent supports. These supports may be selected depending on what the light-sensitive materials are used for. For applying the silver halide emulsion layers and other photographic constituent layers used in this invention, various coating methods can be used, including dip coating, air doctor coating, curtain coating, hopper coating, etc. A coating method of simultaneously applying two or more layers can be also used, according to the method disclosed in U.S. Patents No. 2,761,791 and No. 2,941,898. In this invention, the respective emulsion layers may be applied in any positional order arbitrarily determined. For example, in the case of light-sensitive materials for full color photographic paper, it is preferred to arrange a blue-sensitive silver halide emulsion layer, a green-sensitive silver halide emulsion layer and a red-sensitive silver halide emulsion layer in this order from the support side. These light-sensitive silver halide emulsion layers may each comprise two or more layers. In the light-sensitive material of this invention, an intermediate layer or layers with appropriate thickness may be optionally provided depending on the purpose, and various layers such as a filter layer, an anticurl layer, a protective layer and an antihalation layer can be also used in appropriate combination as constituent layers. In these constituent layers, the above hydrophilic colloid that can be used in emulsion layers can be similarly used as a binding material therefor, and also in the layers the above-mentioned various additives that can be contained in emulsion layers can be contained. The method of processing a light-sensitive silver halide color photographic material of this invention can be applied to any light-sensitive silver halide color photographic materials such as color paper, color negative films, color positive films, color reversal films for slides, color reversal films for motion pictures, color reversal films for televisions, and reversal color paper, if the light-sensitive silver halide color photographic material is a light-sensitive material to be processed according to the so-called internal development system wherein couplers are contained in the light-sensitive material substantially containing the above silver chloride. As described in the foregoing, the processing method of this invention has made it possible to provide a color developing soluiton for processing a light-sensitive silver halide color photographic material that can achieve excellent storage stability and excellent photographic performances for fog and maximum density, and is particularly feasible for rapid processing, and a method employing the same. This invention will be described below more specifically by Examples, but embodiments of this invention are by no means limited to these. Example 1 Color developing solutions each having the following composition were prepared. Made up to 1 liter by adding water, and adjusted to pH 10.15 with use of potassium bydroxide and sulfuric acid. To each of the above color developing solutions, 4 ppm of a ferric ion, 2 ppm of a copper ion and 100 ppm of a calcium ion were added (added by dissolving FeCl₃, CuSO₄·6H₂O and CaCl₂, respectively), and the solutions were stored at 40°C in a glass container having an open top rate of 30 cm²/l (i.e., having an air-contacting area of 30 cm² per 1 liter of the color developing solution) for two weeks. Appearances (coloring degrees) of the color developing solutions after two weeks were observed to obtain the results shown in Table 1. Appearances of the solutions were evaluated by classifying into the following four stages. +++ : A large amount of tar generated ++ : Black colored + : Turned brown (Considerably color-changed) - : Little color-changed As will be clear from the results shown in Table 1, in the cases where sulfates of hydroxylamine are added, color change or blackening has occurred, though somewhat different in appearance depending on whether a chelating agent is present or not, to show that the preservativity is poor. On the other hand, Table 1 clearly shows that, in the cases where the preservatives of this invention were added, the preservativity has been remarkably improved by virtue of the combination with a chelating agent. Example 2 The following layers were provided by coating on paper supports laminated with polyethylene, successively in the order from the support side to produce samples of light-sensitive materials. Layer 1: A layer containing 1.0 g/m² of gelatin, 0.40 g/m² (in terms of silver; ditto hereinafter) of a blue-sensitive silver halide emulsion and 1.0 x 10⁻³ mole/m² of the following yellow coupler (Y-1) dissolved in 0.50 g/m² of dioctyl phthalate. Layer 2: An intermediate layer comprising 0.65 g/m² of gelatin. Layer 3: A layer containing 1.20 g/m² of gelatin, 0.24 g/m² of a green-sensitive silver halide emulsion and 1.0 x 10⁻³ mole/m² of the following magenta coupler (M-1) dissolved in 0.25 g/m² of dioctyl phthalate. Layer 4: An intermediate layer comprising 1.1 g/m² of gelatin. Layer 5: A layer containing 1.3 g/m² of gelatin, 0.27 g/m² of a red-sensitive silver halide emulsion and 1.75 x 10⁻³ mole/m² of the cyan coupler (C-76) mentioned above dissolved in 0.30 g/m² of dibutyl phthalate. Layer 6: A layer containing 1.2 g/m² of gelatin and 0.30 g/m² of Tinuvin 328 (an ultraviolet absorbent produced by Ciba-Geigy Corp.) dissolved in 0.20 g/m² of dioctyl phthalate. Layer 7: A layer containing 0.45 g/m² of gelatin. As a hardening agent, 2,4-dichloro-6-hydroxy-s-triazine sodium salt was added to Layer 2, Layer 4 and Layer 7 each so as to be in an amount of 0.017 g per 1 g of gelatin. Silver halide compositions of respective silver halide emulsion are shown below in Table 2. After carrying out wedgewise exposure on these samples according to a conventional method, the following developing was carried out. Processing solutions used had the following composition. Made up to 1 liter in total by adding water, and adjusted to pH 10.15 with use of potassium hydroxide or sulfuric acid. Made up to 1 liter in total, and adjusted to pH 7.1 with use of potassium carbonate or glacial acetic acid. Maximum reflection density of the yellow dye, obtained when color developing was carried out at 35°C for 10 minutes, was measured with use of an optical densitometer PDA-65 (produced by Konishiroku Photo Industry Co., Ltd. Here, the maximum reflection density of the the yellow dye was assumed as 100, and the developing time (developing completion time) necessary for the maximum reflection density of the yellow dye to be 80 is set forth in Table 2. This result is concerned with a developing completion time for the blue-sensitive emulsion layer having the slowest developing speed, thus showing the time in which the development of a light-sensitive material used has been completed. As will be clear from Table 2, Samples No. 3 to No. 10 having 80 % or more of silver chloride content show that the developing completion time is abort and they are feasible for rapid processing. In particular, it is understood that Samples No. 5 to No. 10 having 90 % or more of silver chloride content, especially, Samples No. 6 to 10 having 95 % or more of silver chloride content are particularly feasible for the rapid processing. Example 3 Example 2 was repeated by using the same color developing solution as in Example 1 and the light-sensitive material as used in example 2 (Sample No. 8) in accordance with the same procedural steps in Example 2, provided for using the color developing solution as used in Example 1 was left to stand for one week by an open top ratio of 10 cm²/l and setting the color development time to 45 seconds. After the processing, the minimum dessity and gamma value (tendency at a concentration of 0.3 to 0.8) of the cyan, magenta and yellow couplers were measured. As a result, there were found that the tendencies of the cyan, magenta and yellow couplers did not changed. The results are shown in Table 3. As will be clear from Table 3, in the case of using the processing soluiton of this invention, there are found that the minimum density and gamma value were changed little even after storage for one weeek at a temperature of 40°C and that remarkable effects can be obtained as compared with the conventional hydroxylamine salts and that the processing solution of the present invention is preferred for rapid processing from the excellent gamma value. Example 4 Using color paper samples used in Example 2, similar processing was repeated following the processing steps in Example 2 and using the processing solutions used in Example 2. However, the silver halide composition in the color paper samples was made to be 1 : 99 of AgBr : AgCl in the blue-sensitive emulsion layer, 5 : 95 in the green-sensitive emulsion layer, and 5 : 95 in the red-sensitive emulsion layer. Cyan couplers used were as shown in Table 4. Color developing processing time was 45 seconds. Concentration of potassium sulfite in the color developing solution was controlled as shown in Table 4. Chelating agents as shown in Table 4 were used in amount of 1.0 g/l. The color developing solution used was obtained by adding 4 ppm of a ferric ion, 2 ppm of a copper ion and 1000 ppm of a calcium ion (added by dissolving FeCl₃, CuSO₄·6H₂O and CaCl₂, respectively), and stored for 5 days under the same conditions in Example 1. The maximum color density and minimum color density of the cyan dye after processing were measured to obtain the results shown in Table 4. As will be clear from the results shown in Table 4, in the cases where the couplers outside this invention are used, there are shown disadvantages that the maximum color density of the cyan dye is greatly decreased and the minimum density is also high. On the other hand, in the cases where the cyan couplers of this invention are used, decrease in the maximum color density is little seen, but the minimum density is extremely high when no chelating agent is present. However, the results satisfying both the maximum color density and the minimum density were obtained by the combination of the coupler of this invention with the chelating agent of this invention. In the samples of this invention, it was also possible to obtain still better maximum color density by lowering the concentration of sulfite. The same results as in the above were also obtained when Exemplary Compounds C-102, C-1, C-3 and C-58 were used as cyan couplers in Sample No. 38, and also when Exemplary Compounds II-1, II-4 to II-7 and III-2 to III-4 were used as chelating agents in Sample No. 36. Comparative cyan couplers: Example 5 Using the light-sensitive color photographic materials produced in Example 2 (silver halide composition is shown in Table 5), the following processing was carried out to evaluate silver-developing properties on the color developing solutions Nos. 2, 4 and 6 (containing no color developing agent). Standard processing steps: (Processing temperature and processing time) Made up to 1 liter in total by adding water, and adjusted to pH 7.00 with used of ammonium hydroxide or acetic acid. After developing processing, using PDA-65 (produced by Konishiroku Photo Industry Co., Ltd.), spectral reflection density was measured on the samples by orange light to evaluate D max of the samples. Difference between the spectral reflection density for D max and the spectral reflection density for D min was assumed as a typical characteristic of silver density. Results are shown in Table 5. As will be clear from Table 5, all of Samples No. 52 to No. 58 using hydroxylamine show high silver density and the silver development is seen to have proceeded. In particular, the silver development is seen to have proceeded in Samples No. 53 to No. 58 having 80 % or more of silver chloride content. However, in the color developing solution No. 6 employing Exemplary Compound I-1 of this invention, the silver development has little taken place regardless of the content of silver chloride. Example 6 Using Samples 1, 3 and 6 used in Example 2 (provided that cyan couplers used are shown in Table 6), and also using the developing solution No. 6 used in Example 1 as a color developing solution (provided that potassium sulfite used is as shown in Table 6), the influence to the cyan density (maximum reflection density) by the silver halide composition and sulfite was examined. Developing processing and evaluation method were in accordance with Example 2. Results obtained are shown in Table 6. As will be clear from Table 6, in the cases where the silver chloride as the silver halide composition is in Samples No. 66 to No. 69, the developing time is so short as to give lower cyan density, but is not so greatly affected by the density of potassium sulfite or the type of cyan couplers. On the other hand, in the Samples No. 70 to No. 77, the cyan density is high even with shorter developing time because of higher developing speed when 80 mole % or more of silver chloride is used, but, when couplers other than those of this invention are used, the density is greatly dependent on the amount of potassium sulfite. The decrease in density is particularly remarkable when 1.0 x 10⁻² or more of potassium sulfite is present, but, in the cases where the couplers of this invention are used, it is seen that the cyan density decreases only a little, and further that very good maximum density can be obtained when the concentration of sulfite is 4.0 x 10⁻³ or less. Example 7 The following layers were provided by coating on paper supports laminated with polyethylene, successively in the order from the support side to produce samples of light-sensitive materials. Layer 1: A layer containing 1.0 g/m² of gelatin, 0.38 g/m² (in terms of silver; ditto hereinafter) of a blue-sensitive silver halide emulsion and 1.0 x 10⁻³ mole/m² of the yellow coupler (Y-1) used in Example 1, dissolved in 0.50 g/m² of dioctyl phthalate. Layer 2: An intermediate layer comprising 0.65 g/m² of gelatin. Layer 3: A layer containing 1.15 g/m² of gelatin, 0.25 g/m² of a green-sensitive silver halide emulsion and 1.0 x 10⁻³ mole/m² of the magenta coupler (M-1) used in Example 1, dissolved in 0.25 g/m² of dioctyl phthalate. Layer 4: An intermediate layer comprising 1.1 g/m² of gelatin. Layer 5: A layer containing 1.3 g/m² of gelatin, 0.28 g/m² of a red-sensitive silver halide emulsion and 1.75 x 10⁻³ mole/m² of the cyan coupler (C-108) dissolved in 0.25 g/m2 of dibutyl phthalate. Layer 6; A layer containing 1.0 g/m² of gelatin and 0.31 g/m² of Tinuvin 328 (an ultraviolet absorbent produced by Ciba-Geigy Corp.) dissolved in 0.20 g/m² of dioctyl phthalate. Layer 7: A layer containing 0.48 g/m² of gelatin. As a hardening agent, 2,4-dichloro-6-hydroxy-s-triazine sodium salt was added to Layer 2, Layer 4 and Layer 7 each so as to be in an amount of 0.017 g per 1 g of gelatin. The silver halide composition in each of the silver halide emulsions is shown in Table 7. On these samples, processing was applied in the following manner: Processing solutions used bad the following composition. Made up to 1 liter in total by adding water, and adjusted to pH 10.15 with use of potassium bydroxide or sulfuric acid. Made up to 1 liter in total, and adjusted to pH 7.1 with use of potassium carbonate or glacial acetic acid. Maximum reflection density of the yellow dye, obtained when color developing was carried out at 35°C for 10 minutes, was measured with use of an optical densitometer PDA-65 (produced by Konishiroku Photo Industry Co., Ltd. Here, the maximum reflection density of the the yellow dye was assumed as 100, and the developing time (developing completion time) necessary for the maximum reflection density of the yellow dye to be 80 is set forth in Table 7. This result is concerned with a developing completion time for the blue-sensitive emulsion layer having the slowest developing speed, thus showing the time in which the development of a light-sensitive material used has been completed. As will be clear from Table 7, Samples No. 80 to No. 87 having 80 % or more of silver chloride content show that the developing completion time is short and they are feasible for rapid processing. In particular, it is understood that Samples No. 82 to No. 87 having 90 % or more of silver chloride content, especially, Samples No. 83 to 87 having 95 % or more of silver chloride content are particularly feasible for the rapid processing. Example 8 Using color paper samples used in Example 7, similar processing was repeated following the processing steps in Example 7 and using the processing solutions used in Example 7. However, the silver halide composition in the color paper samples was made to be 3 : 97 of AgBr : AgCl in the blue-sensitive emulsion layer, 3 : 97 in the green-sensitive emulsion layer, and 1 : 99 in the red-sensitive emulsion layer. Cyan couplers used were as shown in Table 8. Color developing processing time was 45 seconds. Concentration of potassium sulfite in the color developing solution was controlled as shown in Table 8. Chelating agents as shown in Table 8 were used in amount of 1.0 g/l. The color developing solution used was obtained by adding 4 ppm of a ferric ion, 2 ppm of a copper ion and 100 ppm of a calcium ion (added by dissolving FeCl₃, CuSO₄·6H₂O and CaCl₂, respectively), and stored for 5 days under the same conditions in Example 1. The maximum color density and minimum color density of the cyan dye after processing were measured to obtain the results shown in Table 8. As will be clear from the results shown in Table 8, in the cases where the couplers outside this invention are used, there are shown disadvantages that the maximum color density of the cyan dye is greatly decreased and the minimum density is also high. On the other hand, in the cases where the cyan couplers of this invention are used, decrease in the maximum color density is little seen, but the minimum density is extremely high when no chelating agent is present. However, the results satisfying both the maximum color density and the minimum density were obtained by the combination of the coupler of this invention with the chelating agent of this invention. In the samples of this invention, it was also possible to obtain still better maximum color density, by lowering the concentration of sulfite. The same results as in the above were also obtained when Exemplary Compounds C-109 and C-128 were used as cyan couplers in Sample No. 95, and also when Exemplary Compounds II-1, II-4 to II-6 and III-2 to III-4 were used as chelating agents in Sample No. 93. Example 9 Using the light-sensitive color photographic materials produced in Example 7 (silver halide composition is shown in Table 9), the following processing was carried out to evaluate silver-developing properties on the color developing solutions Nos. 2, 4 and 6. Standard processing steps: (Processing temperature and processing time) Made up to 1 liter in total by adding water, and adjusted to pH 7.00 with used of ammonium hydroxide or acetic acid. After developing processing, using PDA-65 (produced by Konisbiroku Photo Industry Co., Ltd.), spectral reflection density was measured on the samples by orange light to evaluate D max of the samples. Difference between the spectral reflection density for D max and the spectral reflection density for D min was assumed as a typical characteristics of silver density. Results obtained are shown in Table 9. As will be clear from Table 9, all of Samples No. 109 to No. 115 using hydroxylamine show high silver density and the silver development is seen to have proceeded. In particular, the silver development is seen to have proceeded in Samples No. 110 to No. 115 having 80 % or more of silver chloride content. However, in the color developing solution no. 26 employing Exemplary Compound I-1 of this invention, the silver development has little taken place regardless of the content of silver chloride. Example 10 Using Samples 78, 80 and 83 used in Example 7 (provided that cyan couplers used are shown in Table 10), and also using the developing solution No. 6 used in Example 1 as a color developing solution (provided that potassium sulfite used is as shown in Table 10), the influence to the cyan density (maximum reflection density) by the silver halide composition and sulfite was examined. Developing processing and evaluation method were in accordance with Example 7. Results obtained are shown in Table 10. As will be clear from Table 10, in the cases where the silver chloride as the silver halide composition is in Samples No. 123 to No. 126), the developing time is so short as to give lower cyan density, but is not so greatly affected by the density of potassium sulfite or the type of cyan couplers. On the other hand, in Samples No. 127 to No. 134), the cyan density is high even with shorter developing time because of higher developing speed when 80 mole % or more of silver chloride is used, but, when couplers other than those used in this invention are used, the density is greatly dependent on the amount of potassium sulfite. The decrease in density is particularly remarkable when 1.0 x 10⁻² or more of potassium sulfite is present, but, in the cases where the couplers of this invention are used, it is seen that the cyan density decreases only a little, and further that very good maximum density can be obtained when the concentration of sulfite is 4.0 x 10⁻³ or less.
