Description: The invention relates to a color image forming process for silver halide color photographic materials giving less fog, showing stable processing performance, and capable of performing quick processing. For forming color images, there is known a process wherein three kinds of yellow, magenta, and cyan couplers are incorporated in light-sensitive emulsion layers, respectively, of a color photographic material and after imagewise exposing the color photographic material, processing it with a color developer containing an aromatic primary amine color developing agent, the oxidation product of which forms colored dyes by a coupling reaction with the couplers. In this case, it is important to color a color photographic material containing silver halide in the smallest possible amount at a high efficiency in a limited development time. For attaining an efficient coloration, it is necessary that the development of silver halide is proceeded as quick as possible without leaving the silver halide to be developed as it is. It is also important that in such a manner of development the oxidation products of the color developing agent are allowed to usefully react with the color couplers. For this purpose, it is known to use a silver halide showing high developing speed or a silver halide having high developing rate. A silver chloride emulsion or a silver chlorobromide emulsion is actually used for this purpose. It is also known that when such a silver halide cannot be used for some reasons, coloring is quickened and increased by increasing the coating amount of silver halide for the amount of color couplers. Furthermore, it is effective to use couplers having high coupling speed and to increase the developing activity of a color developer itself. Various methods have been proposed for increasing the development speed and coloring speed of a color developer. In these methods, it is necessary for forming dyes by the final coupling reaction of a color developing agent and couplers that the color developing agent itself enters coupler-dispersed oil drops. As additives for quickening the permeation of the color developing agent for accelerating coloring, various kinds of additives are known. As an additive having particularly high coloring accelerating effect, benzyl alcohol is known and it has hitherto been used for processing various kinds of color photographic materials and is widely used at present for processing color photographic papers. Benzyl alcohol is poor in solubility in water, although it may be dissolved in water to some extent and, hence, for increasing the solubility thereof, it has been common to use diethylene glycol, triethylene glycol or alkanolamine. These compounds and benzyl alcohol itself, however, give a large load of pollution in processing waste solutions and give high BOD and COD values and, hence, in spite of having the above-described advantages of improving coloring property of color developer and improving the solubility, it has been desired to reduce or eliminate benzyl alcohol from the point of waste solution disposal. Furthermore, even when the aforesaid solvent such as diethylene glycol, is used, the solubility of benzyl alcohol is yet insufficient and, hence, the existence of benzyl alcohol causes troubles in preparing color developer. Also, if benzyl alcohol in color developer is carried over into a succeeding bath, i.e., a bleach bath or a blix bath, together with the color developer and accumulated therein, it causes the formation of a leuco compound of cyan dye according to the kind of cyan dye to reduce coloring density. Furthermore, the accumulation of benzyl alcohol makes it insufficient to wash out the developer components, in particular, the color developing agent in the wash step, which results in the deterioration of the storage stability of color images caused by the residues. From the various viewpoints described above, it is very significant to reduce or eliminate benzyl alcohol in color developer. In addition to the aforesaid problems, color laboratories are at present required to shorten the processing time in a trend of shortening the time for finish delivery of color prints. A process of processing a silver halide photographic material containing cyan, magenta and yellow couplers having specific groups with a color developer containing no benzyl alcohol for 3 min is disclosed in Japanese Patent Application (OPI) Nos. 174836/84 and 177553/84 (the term "OPI" as used herein refers to a "published unexamined Japanese patent application"). However, the development of a new quick processing process giving less reduction of coloring density and less formation of fog even by rapidly processing color photographic materials with a color developer containing no benzyl alcohol for a color development time of less than 2 min and 30 s has been desired. The object of this invention is, therefore, to provide a color image forming process giving less reduction of coloring density even by processing color photographic materials with a color developer containing substantially no benzyl alcohol in a short period of time of not more than 2 min and 30 s, and, in particular, to provide a color image forming process using a color photographic material which gives less fog and is stable when processed under the aforesaid development conditions. Said object is achieved by a colour image forming process, which comprises after imagewise exposing a silver halide color photographic material having on a reflective support at least one light-sensitive emulsion layer containing at least one kind of a monodispersed silver chlorobromide emulsion and a color coupler, said emulsion having been spectrally sensitized by at least one of the compounds represented by the following general formulae (I), (II), (III) and (IV), containing 1 mol % or less silver iodide, containing silver chloride in an amount of from 60 mol% to less than 80 mol% of the total silver halide amount, and having a coefficient of deviation of not more than 20%, developing the color photographic material using a color developer containing less than 1 mℓ/ℓ benzyl alcohol within a development time of 2 min and 30 s: wherein Z₁, Z₂, Z₅ Z₆, Z₇ and Z₈ each represents an atomic group necessary for forming a benzene ring or a naphthalene ring condensed to a thiazole ring or a selenazole ring, said benzene ring or said naphthalene ring may be substituted; Z₃ and Z₄ each represents an atomic group necessary for forming a benzene ring or a naphthalene ring condensed to an oxazole ring, said benzene ring or said naphthalene ring may be substituted; Z₉ represents a hydrocarbon atomic group necessary for forming a 6-membered ring; R₁, R₂, R₃, R₄, R₆, R₇, R₉ and R₁₀ each represents an alkyl group, an alkenyl group, or an aryl group, said groups may be substituted; R₅ and R₈ each represents a hydrogen atom or an alkyl group having 1 to 3 carbon atoms; Y₁, Y₂, Y₃, Y₄, Y₅ and Y₆ each represents a sulfur atom or a selenium atom; X₁ ⊖ represents an anion; and n represents 0 or 1. In a preferred embodiment of this invention, the silver halide color photographic material has at least one each of a blue-sensitive emulsion layer, a green-sensitive emulsion layer, and a red-sensitive emulsion layer as light-sensitive emulsion layers, said blue-sensitive emulsion layer containing the aforesaid monodispersed silver chlorobromide emulsion spectrally sensitized by at least one compound represented by the general formula (I) described above, said green-sensitive emulsion layer containing the aforesaid monodispersed silver chlorobromide emulsion spectrally sensitized by at least one compound represented by the general formula (II) described above, and said red-sensitive emulsion layer containing the aforesaid monodispersed silver chlorobromide emulsion spectrally sensitized by at least one compound represented by the general formula (III) and/or general formula (IV) described above. Also, in a more preferred embodiment of this invention, the light-sensitive emulsion layer containing the aforesaid monodispersed silver chlorobromide emulsion spectrally sensitized by the compound represented by the general formula (II) described above contains at least one compound represented by the general formula (V): wherein R₁₁ represents a hydrogen atom or a substituent; X₂ represents a hydrogen atom or a group capable of being removed by a coupling reaction with the oxidation product of an aromatic primary amine developing agent; Z₁₀, Z₁₁ and Z₁₂ each represents a methine, a substituted methine, =N-, or -NH-; one of Z₁₀-Z₁₁ bond and Z₁₁-Z₁₂ bond is a double bond and the other is a single bond; when Z₁₁-Z₁₂ is a carbon-carbon double bond, the double bond may be a part of an aromatic ring; the compound of general formula (V) may form a dimer or higher polymer at R₁₁ or X₂; and also when Z₁₀, Z₁₁ or Z₁₂ is a substituted methine, the compound includes it may form a dimer or higher polymer with the substituted methine. The concentration of benzyl alcohol is less than 1 mℓ/ℓ, in particular, less than 0.5 mℓ/ℓ. It is preferred that the color developer contains no benzyl alcohol. It is known that silver chloride is developed faster than silver bromide. It can be sufficiently assumed that by utilizing the aforesaid fact, quick processing is easily made by using a silver halide emulsion having an increased silver chloride content. Quick processing by a silver chlorobromide emulsion having an increased silver chloride content is mentioned in Japanese Patent Application (OPI) Nos. 95736/83, 108533/83 and 125612/83. However, the techniques disclosed in these patent applications are not an improvement of the technique itself for performing quick processing using such as high silver chloride-containing emulsion but are techniques for silver halide emulsions relating to the reversing property of the emulsion, the formation of fog, or reproducibility of chemical sensitization, which is also a problem encountered in conventional processing. The present invention is a technique relating to quick processing itself or is a technique relating to a color image forming process by the aforesaid technique. As described above, the elimination of benzyl alcohol from a color developer gives advantages on the preparation of the developer or treatment of waste solution, but at the same time, it gives disadvantages of reducing the coloring density. The inventors have now found that, when benzyl alcohol is omitted from the color developer, not only the coloring density at the gradation portion and the Dmax portion but also the coloring density of fog are reduced, and that the reduction of coloring density is greatly caused by the fact that coloring by coupling does not efficiently occur although silver halide grains having fogged nuclei have been developed as well as the fact that the number of fogged silver halide grains to be developed is reduced. In other words, a part of silver halide grains contributed as grains forming fog in a color developer containing benzyl alcohol becomes grains forming no fog in a color developer containing no benzyl alcohol. This fact is surprising on comparing other facts, confirmed by the inventors, that in a silver halide light-sensitive material containing no color couplers, the number of fogged silver halide grains does not change regardless of the presence of benzyl alcohol in the color developer. As the result of intensive investigations based on the aforesaid matters, the inventors have succeeded in making an invention of a color forming process capable of quickly processing silver halide color photographic materials. As described above, a silver chlorobromide emulsion having a high silver chloride content shows a high development speed and is suitable for quick processing but, at the same time, is liable to form fog. The fog is considered to be caused by silver halide grains already having fogged nuclei before development and silver halide grains newly forming fogged nuclei at development, and that fog is reduced by processing a silver halide color photographic material containing color couplers is considered to be caused by the reduction of fog by the aforesaid two reasons. Accordingly, it can be said that by processing a silver halide photographic material containing a silver chlorobromide emulsion having a high silver chloride content with a color developer containing no benzyl alcohol, quick processing can be attained without forming fog. The silver halide emulsion for use in this invention is a monodispersed silver chlorobromide emulsion containing from 60 mol% to less than 80 mol% silver chloride and containing 1 mol % or less silver iodide, preferably 0.5 mol% or less, and more preferably the content is zero. The presence of silver iodide is undesirable since it lowers the development speed and in some cases increases fog. Also, if the content of silver chloride is less than 60 mol%, the increase of the development speed is insufficient for quick processing and if the content of silver chloride is 80 mol% or more, the stability for processing is inferior to the case of containing less than 80 mol% silver chloride although the formation of fog is lower without using a method disclosed in Japanese Patent Application (OPI) Nos. 97736/83, 108533/83 and 125612/83. In this invention, it is more preferred to use a silver chlorobromide emulsion containing from 65 mol% to 78 mol% silver chloride. The silver halide emulsion for use in this invention is monodispersed in its grain size distribution. The term "monodispersed" means that the value (coefficient of deviation) obtained by dividing the standard deviation in the case of statistically showing diameters corresponding to spheres by a mean sphere equivalent diameter (mean grain size) is not more than 20%, preferably not more than 15%, and more preferably not more than 10%. If the grain size distribution in a silver halide emulsion having a high silver chloride content is broad, in particular, if the emulsion contains a large amount of small grains, the deviation of the photographic performance to the deviation of processing factors undesirably increases. The mean grain size of the silver halide emulsion which can be preferably used in this invention is from 0.003 µm³ to 8 µm³, more preferably from 0.015 µm³ to 4 µm³, and most preferably from 0.03 µm³ to 2 µm³, as calculated in volume. The silver halide grains for use in this invention may have different phases at the inside thereof and on the surface layer thereof, may have a multiphase structure having junction structure, and may be composed of a homogeneous phase throughout the whole grain. Also, the silver halide grains may be composed of a mixture of these grains. The silver halide grains for use in this invention may have a regular crystal form such as cubic, octahedral, dodecahedral, tetradecahedral, an irregular form such as spherical, or a composite form of these crystal forms. Also, the silver halide grains may be tabular grains and, in this case, a tabular grain silver halide emulsion wherein tabular silver halide grains having the ratio of length/thickness of at least 5, and preferably at least 8, account for at least 50% of the total projected area of the silver halide grains can be used in this invention. A mixture of these silver halide emulsions each containing silver halide grains having different crystal forms may also be used. The silver halide emulsion may be of a surface latent image type of forming latent images mainly on the surface thereof or of an internal latent image type of forming latent images mainly in the inside of the grains. The silver halide photographic emulsions for use in this invention can be prepared according to the method described in P. Glafkides, Chimie et Physique Photographique, published by Paul Montel, 1967; G.F. Duffin, Photographic Emulsion Chemistry, published by Focal Press, 1966; and V.L. Zelikman et al., Making and Coating Photographic Emulsion, published by Focal Press, 1964. That is, the emulsion can be prepared by an acid method, a neutralization methods or an ammonia method, and as a method of reacting a soluble silver salt and a soluble halide, a single jet method, a double jet method, or a combination thereof may be employed. A so-called reverse mixing method of forming silver halide grains in the presence of excess silver ions can also be used. As one system of the double jet method, a so-called controlled double jet method of keeping a constant pAg in a liquid phase of forming silver halide grains can also be used. According to the method, a silver halide emulsion containing silver halide grains having a regular crystal form and substantially uniform grain sizes can be obtained. Furthermore, a silver halide emulsion prepared by a conversion method including a step of converting a silver halide already formed before finishing the formation of the silver halide grains into a silver halide having small solubility product or a silver halide emulsion to which the similar halogen conversion was applied after finishing the formation of the silver halide grains can also be used in this invention. During the formation or physical ripening of the silver halide grains,for example, a cadmium salt, a zinc salt, a thallium salt, an iridium salt or a complex salt thereof, a rhodium salt or a complex salt thereof, an iron salt or a complex salt thereof, may exist in the system. After the formation of the silver halide grains silver halide emulsions are usually physically ripened, desalted, and chemically ripened before coating. Known silver halide solvents (e.g., ammonia, potassium rhodanate, thioethers and thione compounds described in U.S. Patent 3,271,157, Japanese Patent Application (OPI) Nos. 12360/76, 82408/78, 144319/78, 100717/79, 155828/79) can be used for the precipitation, physical ripening, and chemical ripening of the silver halide emulsions for use in this invention. For removing soluble salts from silver halide emulsions after physical ripening, a noodle washing method, a flocculation method, or an ultrafiltration method can be employed. The silver halide emulsions for use in this invention can be chemically sensitized by a sulfur sensitization method using active gelatin or a sulfur-containing compound capable of reacting with silver (e.g., thiosulfates, thioureas, mercapto compounds, rhodanines); a reduction sensitization method using a reducing compound (e.g., stannous salts, amines, hydrazine derivatives, formamidinesulfinic acid, silane compounds); a noble metal sensitization method using a metal compound (e.g., gold complex salts and complex salts of metals belonging to group VIII of the Periodic Table, such as Pt, Ir, Pd, Rh, Fe), or a combination thereof. In the aforesaid chemical sensitizations, the use of the sulfur sensitization alone is more preferred. In this invention, two or more kinds of monodispersed silver halide emulsions (preferably having the aforesaid coefficient of deviation) having different grain sizes can be used for one layer or two or more layers in a silver halide emulsion layer having substantially the same color sensitivity for satisfying the gradation aimed by the color photographic material for use in this invention. Furthermore, two or more kinds of polydispersed silver halide emulsions or a combination of the monodispersed silver halide emulsion and a poly-dispersed silver halide emulsion can be used in one layer as a mixture thereof or for two or more layers. For applying the silver halide emulsions in this invention to color photographic materials, it is necessary to spectrally sensitize the emulsions for obtaining desired color sensitivities. In this invention, by processing a silver halide color photographic material containing a silver chlorobromide emulsion containing from 60 mol% to less than 80 mol% silver chloride and containing 1 mol % or less silver iodide with a color developer containing less than 1 mℓ/ℓ benzyl alcohol, quick processing without being accompanied by the formation of fog can be applied as described above and in the course of the investigations for finding the aforesaid fact, it has been clarified that the extent of fog formation at processing and the development rate are greatly influenced by the kind of the spectral sensitizing dye used. That is, it has been found that according to the spectral sensitizing dye used, there are cases that fog forms and the effect for improving development speed is insufficient even in the case of processing the above-described silver halide emulsion with a color developer containing no benzyl alcohol. In view of the aforesaid points, the inventors have made intensive investigations and found that, by processing a silver halide color photographic material containing monodispersed silver halide emulsion(s) spectrally sensitized by at least one of the compounds represented by the general formulae (I), (II), (III) and (IV) described above, containing from 60 mol% to less than 80 mol% silver chloride, and containing 1 mol % or less silver iodide, a color image formation with the formation of fog restrained greatly and with excellent developing speed becomes possible. The compounds shown by the general formulae (I) to (IV) described above will be explained in detail. In the general formulae (I), (II), (III) and (IV) described above, Z₁, Z₂, Z₅, Z₆, Z₇ and Z₈ each represents an atom necessary for forming a benzene ring or a naphthalene ring each condensed to a thiazole ring or a selenazole ring, and each of the rings may be substituted by a halogen atom such as a fluorine atom, a chlorine atom, a bromine atom or an iodine atom, a hydroxyl group, an alkyl group such as a methyl group, an ethyl group, a propyl group or a butyl group, an alkoxy group such as a methoxy group or an ethoxy group, an aryl group such as a phenyl group or a hydroxyphenyl group, an alkoxycarbonyl group such as a methoxycarbonyl group or an ethoxycarbonyl group, a cyano group or a nitro group. As these substituents, a halogen atom, an alkoxy group or an aryl group is preferred in this invention and as a halogen atom, a chlorine atom is particularly preferred, as an alkoxy group, a methoxy group is particularly preferred, and as an aryl group, a phenyl group is particularly preferred. Also, Z₃ and Z₄ in the aforesaid formulae represents an atomic group necessary for forming a benzene ring or a naphthalene ring condensed to an oxazole ring and each of the rings may be substituted by a halogen atom such as a fluorine atom, a chlorine atom, a bromine atom or an iodine atom, a hydroxyl group, an alkoxy group such as a methoxy group, an ethoxy group or a propoxy group, an aryl group such as a phenyl group or a hydroxyphenyl group, an alkoxycarbonyl group such as a methoxycarbonyl group or an ethoxycarbonyl group, a cyano group or a nitro group. As these substituents, a halogen atom, an alkoxy group, or an aryl group is preferred in this invention, and as a halogen atom, a chlorine atom is particularly preferred, as an alkoxy group, a methoxy group is particularly preferred, and as an aryl group, a phenyl group is particularly preferred. Z₉ represents a hydrocarbon atomic group necessary for forming a 6-membered ring such as, preferably, a dimethylcyclohexene ring. In the general formulae (I), (II), (III) and (IV) described above, R₁, R₂, R₃, R₄, R₆, R₇, R₉ and R₁₀ each represents an alkyl group, an alkenyl group, an aralkyl group, or an aryl group and these groups may be substituted by a hydroxyl group, a sulfone group or a carboxyl group. Preferred examples of the aforesaid groups are a methyl group, an ethyl group, an n-propyl group, an i-propyl group, an n-butyl group, a hydroxymethyl group, a hydroxyethyl group, a hydroxypropyl group, a sulfoethyl group, a sulfopropyl group, a sulfobutyl group, a carboxymethyl group, a carboxyethyl group, a benzyl group, a phenethyl group and a propenyl group. As these substituents, an alkyl group having 1 to 5 carbon atoms, a sulfoalkyl group having 2 to 4 carbon atoms, a carboxyalkyl group having 2 to 5 carbon atoms, or an aralkyl group is particularly preferred in this invention. Also, R₅ and R₈ each represents a hydrogen atom or an alkyl group having 1 to 3 carbon atoms. In the general formulae (I), (II), (III) and (IV), Y₁ to Y₆ each represents a sulfur atom or a selenium atom and X ⊖ represents an anion, and n represents 0 or 1 and when n is 0, the compound of the formula forms an intramolecular salt. Specific examples of the compound of the general formula (I) are illustrated below. Specific examples of the compound shown by general formula (II) are illustrated below but the invention is not limited to these compounds. Specific examples of the compound shown by general formula (III) are illustrated below but the invention is not limited to these compounds. Specific examples of the compound of the general formula (IV) are illustrated below. The added amount of the compound of the general formula (I), (II), (III) or (IV) described above varies widely case by case but is in the range of from 1.0 × 10⁻⁶ mol to 5.0 × 10⁻² mol, and preferably in the range of from 1.0 × 10⁻⁵ mol to 1.0 × 10⁻² mol per mol of silver halide. For spectrally sensitizing a silver halide emulsion with the aforesaid compound used in this invention, a well-known ordinary method may be used. That is, the compound may be directly dispersed in a silver halide emulsion or the compound may be added to a silver halide emulsion as a solution in a proper solvent (e.g., methanol, ethanol, ethyl acetate, methyl cellosolve, acetone, fluorinated alcohol, or a mixture thereof). Furthermore, a method of dissolving the compound in a volatile organic solvent, dispersing the solution in an aqueous hydrophilic colloid solution, and adding the dispersion to a silver halide emulsion as described in U.S. Patent 3,469,987 may be used. The addition of the aforesaid compound can be performed in any step for the preparation of a silver halide emulsion. For example, the compound is added before, during, or after the formation of silver halide grains, before, during, or after chemical ripening of silver halide grains, or at the time of the preparation of a coating composition for a light-sensitive emulsion layer. In this invention, it is preferred to add the compound after the formation of silver halide grains, before chemical ripening, during chemical ripening, or after chemical ripening. It is necessary that the light-sensitive emulsion layers of a color photographic light-sensitive material for use in this invention contain color couplers for forming color images. A color coupler used in this invention is a compound capable of forming a colored dye by causing a coupling reaction with the oxidation product of an aromatic primary amine developing agent. Typical examples of these preferred color couplers are yellow coloring couplers selected from open chain or heterocyclic ketomethylene compounds, magenta coloring couplers selected from pyrazolone series and pyrazoloazole series compounds, and cyan coloring couplers selected from naphtholic and phenolic compounds. It is clear that for forming color images with less reduction in coloring density even in the case of applying processing of a short period of time using a color developer containing, less than 1 mℓ/ℓ benzyl alcohol, the selection of these color couplers is also an important factor in addition to the techniques of silver halide emulsions and the spectral sensitization for these emulsions as described above. According to the result of the inventors' investigations, it has newly been found that when the color couplers illustrated above as typical examples are applied to a color photographic material in this invention and the color photographic material is processed in a short period of time by a color developer containing less than 1 mℓ/ℓ benzyl alcohol, these color couplers show good coloring property and, in particular, pyrazoloazole series compounds are specifically excellent in coloring property. The pyrazoloazole series magenta couplers are the compounds of the general formula (V) described hereinbefore. A polymer in the general formula (V) means a compound having two or more groups shown by the general formula (V) in one molecule and bis compounds and polymer couplers are included in the polymer. The polymer coupler may be a homopolymer composed of only a monomer (preferably, having a vinyl group, hereinafter, the monomer is referred to as vinyl monomer) having a moiety of the general formula (V) described above or may be a copolymer composed of the aforesaid vinyl monomer and a non-coloring ethylenically unsaturated monomer which does not cause coupling with the oxidation product of an aromatic primary amine developing agent. The compound of the general formula (V) described above is a 5-membered ring-5-membered ring-condensed nitrogen-containing heterocyclic ring type coupler, its coloring mother nucleus shows an aromaticity equivalent to naphthalene, and has a chemical structure usually called azapentalene. Preferred examples of the couplers of the general formula (V) are 1H-imidazo[1,2-b]pyrazoles, 1H-pyrazolo[1,5-b]pyrazoles, 1H-pyrazolo[5,1-c][1,2,4]triazoles, 1H-pyrazolo[1,5-b][1,2,4]triazoles, 1H-pyrazolo[1,5-d]tetrazoles, and 1H-pyrazolo[1,5-a]benzimidazoles, which are represented by the general formulae (VI), (VII), (VIII), (IX), (X) and (XI) described below, respectively. Of these compounds, preferred compounds are those of the general formulae (VI), (VIII) and (IX), and particularly preferred compounds are those of the general formulae (VI) and (IX). In the general formulae (VI) to (XI), R₁₂, R₁₃ and R₁₄ each represents a hydrogen atom, a halogen atom, an alkyl group, an aryl group, a heterocyclic group, a cyano group, an alkoxy group, an aryloxy group, a heterocyclic oxy group, an acyloxy group, a carbamoyloxy group, a silyloxy group, a sulfonyloxy group, an acylamino group, an anilino group, a ureido group, an imido group, a sulfamoylamino group, a carbamoylamino group, an alkylthio group, an arylthio group, a heterocyclic thio group, an alkoxycarbonylamino group, an aryloxycarbonylamino group, a sulfonamido group, a carbamoyl group, an acyl group, a sulfamoyl group, a sulfonyl group, a sulfinyl group, an alkoxycarbonyl group, or an aryloxycarbonyl group; and X₂ represents a hydrogen atom, a halogen atom, a carboxyl group or a group which is bonded to a carbon atom at the coupling position through an oxygen atom, a nitrogen atom or a sulfur atom and causes coupling releasing.

In particularly preferred compounds of the general formula (XII) described above, R₁₄ is an alkoxy group, a ureido group, or an aryloxy group and R₁₅ is an alkyl group (including its substituted group). Also, in particularly preferred compounds of the general formula (XIII) described above, R₁₄ is an alkyl group or an alkoxy group and R₁₅ is an alkylthio group.

Examples and synthesis methods of the couplers of the general formulae (VI) to (XI) described above are described in the following literature. The compounds of the general formula (VI) are described in Japanese Patent Application (OPI) No. 162548/84, the compounds of the general formula (VII) in Japanese Patent Application (OPI) No. 43659/84, the compounds of the general formula (VIII) in Japanese Patent Publication No. 27411/72, the compounds of the general formula (IX) in Japanese Patent Application (OPI) Nos. 171956/84 and 172982/85, the compounds of the general formula (X) in Japanese Patent Application (OPI) No. 33552/85, and the compounds of the general formula (XI) in U.S. Patent 3,061,432.

Specific examples of the pyrazoloazole series couplers shown by the aforesaid formulae for use in this invention are illustrated below. It is preferred that the color couplers contained in the photographic materials for use in this invention are rendered nondiffusible by a ballast group or by being polymerized. The use of 2-equivalent color couplers, the coupling active position of which is substituted by a releasing group, is more effective in reducing the amount of silver than 4-equivalent color couplers having a hydrogen atom at its coupling active position. Couplers providing colored dyes having a proper diffusibility, non-coloring couplers, DIR couplers releasing a development inhibitor with the coupling reaction, or couplers releasing a development accelerator with the coupling reaction thereof can also be used. Typical examples of the yellow couplers for use in this invention are oil-protect type acylacetamide series yellow couplers. Specific examples thereof are described in U.S. Patents 2,407,210, 2,875,057 and 3,265,506. In this invention, the use of 2-equivalent yellow couplers is preferred and typical examples thereof are oxygen atom-releasing type yellow couplers described in U.S. Patents 3,408,194, 3,447,928, 3,933,501 and 4,022,620, and nitrogen atom-releasing type yellow couplers described in Japanese Patent Publication No. 10739/83, U.S. Patents 4,401,752 and 4,326,024, Research Disclosure, No. 18053 (April, 1979), British Patent 1,425,020, West German Patent Application (OLS) Nos. 2,219,917, 2,261,361, 2,329,587 and 2,433,812. Of these couplers, α-pivaloylacetanilide series couplers are excellent in fastness, while α-benzoylacetanilide series couplers give high coloring density. As the magenta couplers for use in this invention there may be mentioned oil-protect type indazolone series or cyanoacetyl series magenta couplers, preferably 5-pyrazolone series couplers and pyrazoloazole series couplers such as pyrazolotriazole series couplers. The 5-pyrazolone series couplers having an arylamino group or an acylamino group at the 3-position thereof are preferred from the viewpoint of the hue of the colored dyes and the coloring density, and typical examples of the couplers are described in U.S. Patents 2,311,082, 2,343,703, 2,600,788, 2,908,573, 3,062,653, 3,152,896 and 3,936,015. Preferred releasing groups for the 2-equivalent 5-pyrazolone series magenta couplers include nitrogen atom-releasing groups described in U.S. Patent 4,310,619 and arylthio groups described in U.S. Patent 4,351,897. Also, 5-pyrazolone series couplers having a ballast group described in European Patent 73,636 give high coloring density. As described hereinbefore, pyrazoloazole series couplers are particularly preferred in this invention and practically they are selected from the compounds of the general formula (V) described above. Cyan couplers for use in this invention include oil-protect type naphtholic and phenolic couplers. Typical examples of the cyan couplers are naphtholic couplers described in U.S. Patent 2,474,293, and preferably oxygen atom-releasing type 2-equivalent naphtholic couplers described in U.S. Patents 4,052,212, 4,146,396, 4,228,233 and 4,296,200. Also, specific examples of the phenolic couplers are described in U.S. Patents 2,369,929, 2,801,171, 2,772,162 and 2,895,826. Cyan couplers having high fastness to moisture and heat are preferably used in this invention, and typical examples thereof are the phenolic cyan couplers having an alkyl group of 2 or more carbon atoms at the meta-position of the phenol nucleus described in U.S. Patent 3,772,002, 2,5-diacylamino-substituted phenolic couplers described in U.S. Patents 2,772,162, 3,758,308, 4,126,396, 4,334,011 and 4,327,173, West German Patent Application (OLS) No. 3,329,729 and Japanese Patent Application (OPI) No. 166956/84, and phenolic couplers having a phenulureido group at the 2-position and an acylamino group at the 5-position thereof described in U.S. Patents 3,446,622, 4,333,999, 4,451,559 and 4,427,767. In this invention, the graininess of the color images formed can be improved by simultaneously using a coupler giving colored dye having a proper diffusibility and the aforesaid coupler(s). For such couplers giving diffusible dyes, specific examples of the magenta couplers are described in U.S. Patent 4,366,237 and British Patent 2,125,570 and specific examples of the yellow, magenta, and cyan couplers are described in European Patent 96,570 and West German Patent Application (OLS) No. 3,234,533. The dye-forming couplers and the specific couplers described above may form a dimer or higher polymer. Typical examples of the polymerized dye-forming couplers are described in U.S. Patents 3,451,820 and 4,080,211. Also, specific examples of the polymerized magenta couplers are described in British Patent 2,102,173 and U.S. Patent 4,367,282. The couplers for use in this invention can be used in one light-sensitive emulsion layer as a mixture of two or more couplers for meeting the properties required for the color photographic material or the same kind of coupler may be incorporated into two or more photographic emulsion layers. The couplers for use in this invention can be introduced into silver halide emulsions by an oil drop-in-water dispersion method. That is, in the oil drop-in-water dispersion method, the coupler is dissolved in a high boiling organic solvent having a boiling point of at least 175°C or a low boiling solvent, a so-called auxiliary solvent, or a mixture of both types of solvents, and then finely dispersed in water or an aqueous meidum such as an aqueous gelatin solution in the presence of a surface active agent. Examples of the high boiling organic solvent are described in U.S. Patent 2,322,027. In this case, the coupler may be dispersed with phase inversion and also, if necessary, the auxiliary solvent may be removed by distillation, noodle washing, or ultrafiltration before coating the dispersion. Specific examples of the high boiling organic solvent are phthalic acid esters (e.g., dibutyl phthalate, dicyclohexyl phthalate, di-2-ethylhexyl phthalate or decyl phthalate), phosphoric acid esters or phosphonic acid esters (e.g., triphenyl phosphate, tricresyl phosphate, 2-ethylhexyldiphenyl phosphate, tricyclohexyl phosphate, tri-2-ethylhexyl phosphate, tridecyl phosphate, tributoxyethyl phosphate, trichloropropyl phosphate or di-2-ethylhexylphenyl phosphate), benzoic acid esters (e.g., 2-ethylhexyl benzoate, dodecyl benzoate, or 2-ethylhexyl-p-hydroxy benzoate, amides (e.g., diethyldodecanamide or N-tetradecylpyrrolidone), alcohols or phenols (e.g., isostearyl alcohol or 2,4-di-tert-amylphenol), aliphatic carboxylic acid esters (e.g., dioctyl acetate, glycerol tributyrate, isostearyl lactate or trioctyl citrate), aniline derivatives (e.g., N,N-dibutyl-2-butoxy-5-tert-octylaniline) and, hydrocarbons (e.g., paraffin, dodecylbenzene or diisopropylnaphthalene). As the auxiliary solvent, organic solvents having a boiling point of at least about 30°C, preferably from about 50°C to about 160°C can be used and specific examples thereof are ethyl acetate, butyl acetate, ethyl propionate, methyl ethyl ketone, cyclohexanone, 2-ethoxyethyl acetate and dimethylformamide. The process and effect of the latex dispersion method and specific examples of the latex for impregnation are described in U.S. Patent 4,199,363, West German Patent Application (OLS) Nos. 2,541,274 and 2,541,230. A standard amount of the color coupler is in the range of from 0.001 mol to 1 mol per mol of the light-sensitive silver halide, from 0.01 mol to 0.5 mol of a yellow coupler, from 0.003 to 0.3 mol of a magenta coupler, and from 0.002 mol to 0.3 mol of a cyan coupler being preferred. The color photographic materials for use in this invention may further contain hydroquinone derivatives, aminophenol derivatives, amines, gallic acid derivatives, catechol derivatives, ascorbic acid derivatives, colorless compound-forming couplers or sulfonamidophenol derivatives, as color fogging preventing agents or color mixing preventing agents. Also, the color photographic materials for use in this invention can further contain discoloration preventing agents. Typical examples of organic discoloration preventing agents are hydroquinones, 6-hydroxychromans, 5-hydroxycoumarans, spirochromans, p-alkoxyphenols, hindered phenols including bisphenols, gallic acid derivatives, methylenedioxybenzenes, aminophenols, hindered amines and ether or ester derivatives of the aforesaid compounds obtained by silylating or alkylating the phenolic hydroxyl group of these compounds. Metal complexes such as (bissalicylaldoxymate) nickel complex and (bis-N,N-dialkyldithiocarbamate) nickel complex can also be used as the discoloration preventing agent. For preventing the deterioration of yellow dye images by heat, moisture, and light, a compound having both moieties of hindered amine and hindered phenol in one molecule as described in U.S. Patent 4,268,593 gives good results. Also, for preventing the deterioration of magenta dye images, particularly by light, spiroindans described in Japanese Patent Application (OPI) No. 159644/81 and chromans substituted by hydroquinone diether or hydroquinone monoether described in Japanese Patent Application (OPI) No. 89835/80 give preferred results. For improving the storage stability, in particular, the light fastness of cyan images, it is preferred to use a benzotriazole series ultraviolet absorber with the cyan coupler(s). The ultraviolet absorber may be co-emulsified with the cyan coupler(s). The amount of the ultraviolet absorber is desirably sufficient for imparting light stability to cyan dye images, but since if the amount is too much, the unexposed portions (background portions) of the color photographic material are sometimes yellowed, the amount thereof is usually selected in the range of from 1 × 10⁻⁴ mol/m² to 2 × 10⁻³ mol/m², particularly from 5 × 10⁻⁴ mol/m² to 1.5 mol/m². In the layer structure of an ordinary color photographic paper, the ultraviolet absorber(s) are incorporated in one or both layers adjacent to a red-sensitive silver halide emulsion layer containing cyan coupler. When the ultraviolet absorber(s) are incorporated in the interlayer between a green-sensitive emulsion layer and a red-sensitive emulsion layer, the ultraviolet absorber(s) may be emulsified together with a color mixing preventing agent. When ultraviolet absorbers are incorporated in a protective layer, another protective layer may be formed on the protective layer as the outermost layer. The outermost protective layer may contain a matting agent having a proper particle size. The color photographic material for use in this invention may further contain ultraviolet absorber in the hydrophilic colloid layer. The color photographic materials for use in this invention may further contain water-soluble dyes in the hydrophilic colloid layers as filter dyes or for the purpose of irradiation prevention or halation prevention. The color photographic materials for use in this invention may further contain whitening agents such as stilbene series, triazine series, oxazole series, or coumarin series whitening agents in the photographic emulsion layers or other hydrophilic colloid layers. The whitening agent may be water-soluble or a water-insoluble whitening agent may be used in the form of a dispersion. The process of this invention can be applied to a multilayer multicolor photographic material having on a support at least two photographic emulsion layers each having different spectral sensitivity as described above. A multilayer natural color photographic material usually has at least one red-sensitive emulsion layer, at least one green-sensitive emulsion layer, and at least one blue-sensitive emulsion layer on a support. The disposition order of the emulsion layers can be optionally selected according to the purposes. Also, each of the aforesaid emulsion layers may be composed of two or more emulsion layers each having different light sensitivity or a light-insensitive layer may exist between two or more emulsion layers each having the same sensitivity. The color photographic material for use in this invention preferably has auxiliary layers such as a protective layer, interlayers, a filter layer, an antihalation layer or a back layer, in addition to the silver halide emulsion layers. As a binder or protective colloid which can be used in the emulsion layers and auxiliary layers of the color photographic material for use in this invention, gelatin is advantageously used but other hydrophilic colloids may also be used. Examples of the protective colloid are proteins such as gelatin derivatives, graft polymers of gelatin and other polymers, albumin or casein, cellulose derivatives such as hydroxyethyl cellulose, carboxymethyl cellulose or cellulose sulfuric acid ester; saccharose derivatives, such as sodium alginate or starch derivatives; and synthetic hydrophilic polymers such as polyvinyl alcohol, polyvinyl alcohol partial acetal, poly-N-vinylpyrrolidone, polyacrylic acid, polymethacrylic acid, polyacrylamide, polyvinylimidazole or polyvinylpyrazole. As gelatin, limed gelatin as well as acid-treated gelatin and enzyme-treated gelatin as described in Bull. Soc. Sci. Phot. Japan, No. 16, p. 30 (1966) can be used. Furthermore, hydrolyzed product or enzyme-decomposed product of gelatin can be used. The color photographic materials for use in this invention may further contain various stabilizers, stain preventing agents, developing agents or the precursors therefor, development accelerators or the precursors therefor, lubricants, mordants, matting agents, antistatic agents, plasticizers, or any other photographically useful additives in addition to the above-described additives. Typical examples of such additives are described in Research Disclosure, No. 17643 (December, 1978) and ibid., No. 18716 (November, 1979). The "reflective support" for the color photographic material which is used in this invention is a support having high reflectivity for clearly viewing color images formed in silver halide emulsion layer(s) and includes a support coated with a hydrophobic resin with a light reflective material dispersed therein such as titanium oxide, zinc oxide, calcium carbonate or calcium sulfate, and a support composed of a hydrophobic resin containing the light reflective material as described above. Examples of such a support are baryta papers, polyethylene-coated papers, polypropylene series synthetic papers, and transparent support having a reflective layer or containing a reflective material. Examples of the transparent support are glass plates, polyester films (e.g., polyethylene terephthalate films, cellulose triacetate films or cellulose nitrate films), polyamide films, polycarbonate films and polystyrene films. Then, the processing process (image-forming process) of this invention will be described. The processing time for the color processing steps in this invention is not longer than 2 min and 30 s, and preferably from 30 to 2 min. The processing time in this invention is the time required for a color photographic material from the contact with a color developer to the contact with a subsequent bath and includes the traveling time between the baths. The color developer which is used for the processing process of this invention is an aqueous alkaline solution containing an aromatic primary amine color developing agent as the main component. As the color developing agent, p-phenylenediamine series compounds are preferably used and typical examples thereof are 3-methyl-4-amino-N,N-diethylaniline, 3-methyl-4-amino-N-ethyl-N-β-hydroxyethylaniline, 3-methyl-4-amino-N-ethyl-N-β-methanesulfonamidoethylaniline, 3-methyl-4-amino-N-ethyl-N-β-methoxyethylaniline, sulfates, hydrochlorides, phosphates, or p-toluenesulfonates thereof, tetraphenylborates and p-(t-octyl)benzenesulfonates. Examples of aminophenol derivatives which can also be used as the color developing agent include o-aminophenol, p-aminophenol, 4-amino-2-methylphenol, 2-amino-3-methylphenol and 2-oxy-3-amino-1,4-dimethylbenzene. Other color developing agents described in L.F.A. Mason, Photographic Processing Chemistry, pages 226-229, Focal Press, U.S. Patents 2,193,015 and 2,592,364 and Japanese Patent Application (OPI) No. 64933/73, may also be used in this invention. If necessary, two or more kinds of these color developing agents can also be used in combination. The processing temperature in the color developer in this invention is preferably from 30°C to 50°C, and more preferably from 33°C to 42°C. As development accelerators, various kinds of compounds substantially excluding benzyl alcohol may be used for the color developer in this invention. Examples of these compounds are pyridinium compounds described in U.S. Patent 2,648,604, Japanese Patent Publication No. 9503/69, and U.S. Patent 3,171,247 and other cationic compounds; cationic dyes such as phenofuranin; neutral salts such as thallium nitrate and potassium nitrate; nonionic compounds such as polyethylene glycol, derivatives thereof, and polythioether described in Japanese Patent Publication No. 9304/69, U.S. Patents 2,533,990, 2,531,832, 2,950,970 and 2,577,127; thioether series compounds described in U.S. Patent 3,201,242; and other compounds described in Japanese Patent Application (OPI) Nos. 156934/83 and 220344/85. Also, in a short processing process as in this invention, not only a means for accelerating development but also a technique for preventing the formation of development fog are important. As the antifoggant in this invention, alkali metal halide such as potassium bromide, sodium bromide or potassium iodide, and organic antifoggants are preferred. Examples of organic antifoggants which can be used in this invention include nitrogen-containing heterocyclic compounds such as benzotriazole, 6-nitrobenzimidazole, 5-nitroisoindazole, 5-methylbenzotriazole, 5-nitrobenzotriazole, 5-chlorobenzotriazole, 2-thiazolylbenzimidazole, 2-thiazolylmethylbenzimidazole, hydroxyazaindolizine, etc., mercapto-substituted heterocyclic compounds such as 1-phenyl-5-mercaptotetrazole, 2-mercaptobenzimidazole or 2-mercaptobenzothiazole, and mercapto-substituted aromatic compounds such as thiosalicylic acid. The halides are particularly preferred. These antifoggants may be dissolved off from color photographic materials during processing and may be accumulated in a color developer. It is well known that the concentration of Br⁻ ion contained in a color developer greatly changes the development speed, and known in the art are a standard processing type of performing color development for 3 min and 30 s at 33°C with a KBr concentration of about 0.5 g/l and a low replenisher type of performing color development for 30 s at 38°C with a KBr concentration of about 1 g/l. By increasing the KBr concentration from 0.5 g/l to 1 g/l for low replenisher processing, it is required to raise the development temperature by 5°C. In the process of this invention, the amount of Br⁻ ion released from color photographic materials is low and, hence, it is possible to increase the development speed as a color developer of lower KBr concentration. Also, it is possible to form a low replenisher color developer by utilizing the lower Br⁻ ion-releasing property and also an intermediate between the two cases can be selected. A preferred Br⁻ ion concentration in a color developer for use in this invention is from 1 × 10⁻² mol/l to 4.2 × 10⁻⁴ mol/l. More preferably, the Br⁻ ion concentration is from 5 × 10⁻³ mol/l to 6.7 × 10⁻⁴ mol/l, and most preferably from 3.3 × 10⁻³ mol/l to 8.4 × 10⁻⁴ mol/l. Moreover, the color developers for use in this invention may further contain pH buffers such as carbonates, borates, or phosphates of an alkali metal; preservatives such as hydroxylamine, triethanolamine, the compounds described in West German Patent Application (OLS) No. 2,622,950, sulfites or bisulfites, organic solvents such as diethylene glycol; dye-forming couplers; competing couplers; nucleating agents such as sodium borohydride; auxiliary developing agents such as 1-phenyl-3-pyrazolidone; viscosity-imparting agents; and chelating agents such as aminopolycarboxylic acids (e.g., ethylenediaminetetraacetic acid, nitrilotriacetic acid, cyclohexanediaminetetraacetic acid, iminodiacetic acid, N-hydroxymethylethylenediaminetriacetic acid, diethylenetriaminepentaacetic acid, triethylenetetraminehexaacetic acid, and the compounds described in Japanese Patent Application (OPI) No. 195845/83), 1-hydroxyethylidene-1,1'-diphosphonic acid, organic phosphonic acids described in Research Disclosure, No. 18170 (May, 1979), aminophosphonic acids (e.g., aminotris(methylenephosphonic acid or ethylenediamine-N,N,N'-tetramethylenephosphonic acid), and phosphonocarboxylic acids described in Japanese Patent Application (OPI) Nos. 102726/77, 42730/78, 121127/79, 4024/80, 4025/80, 126241/80, 65955/80, 65956/80, and Research Disclosure, No. 18170 (May, 1979). Also, the color developing bath or tank may be composed of two or more baths and a color developer replenisher may be supplied from the foremost bath or the last bath to shorten the development time and reduce the amount of replenisher. A silver halide color photographic material is, after color development, usually subjected to bleach processing. The bleach processing may be performed simultaneously with a fix processing (bleach-fix or blix processing) or separately from the fix processing. As a bleaching agent, compounds of multivalent metals such as iron(III), cobalt(III), chromium(VI) or copper(II), peracids, quinones and nitroso compounds are used. Examples of the bleaching agent include ferricyanides, bichromates, organic complex salts of iron(III) or cobalt(III), complex salts of aminopolycarboxylic acids (e.g., ethylenediaminetetraacetic acid, diethylenetriaminepentaacetic acid, nitrilotriacetic acid or 1,3-diamino-2-propanoltetraacetic acid) or of other organic acids (e.g., citric acid, tartaric acid or malic acid), persulfates, manganates or nitrosophenol. Of the aforesaid compounds, potassium ferricyanide, ethylenediaminetetraacetic acid iron(III) sodium, ethylenediaminetetraacetic acid iron(III) ammonium, triethylenetetraminepentaacetic acid(III) ammonium, and persulfates are particularly useful. Ethylenediaminetetraacetic acid iron(III) complex salts are useful for both bleach solution and blix solution. Also, the bleach solution or blix solution may further contain, if necessary, various accelerators. Examples of the accelerator are bromide ions and iodide ions as well as thiourea series compounds described in U.S. Patent 3,706,561, Japanese Patent Publication Nos. 8506/70 and 26586/74, Japanese Patent Application (OPI) Nos. 32735/78, 36233/78 and 37016/78, thiol series compounds described in Japanese Patent Application (OPI) Nos. 124424/78, 95631/78, 57831/78, 32736/78, 65732/78, 52534/79, and U.S. Patent 3,893,858, heterocyclic compounds described in Japanese Patent Application (OPI) Nos. 59644/74, 140129/75, 28426/78, 141623/78, 104232/78 and 35727/79, thioether series compounds described in Japanese Patent Application (OPI) Nos. 20832/77, 25064/80 and 26506/80, quaternary amines described in Japanese Patent Application (OPI) No. 84440/73, and thiocarbamoyls described in Japanese Patent Application (OPI) No. 42349/74. As a fixing agent, there may be mentioned thiosulfates, thiocyanates, thioether series compounds, thioureas, and a large number of iodides but generally a thiosulfate is used. As preservatives for blix solution or fix solution, sulfites, bisulfites, or carbonyl-bisulfite addition products are preferably used. After the blix process or fix process, a washing process is usually performed. For the wash processing step, various compounds may be used for preventing the occurrence of precipitations and saving water. Examples of these additives are water softeners such as inorganic phosphoric acids, aminopolycarboxylic acids and organic phosphoric acids, antibacterial agents and antifungal agents for preventing the generation of bacteria, molds, and algae, hardening agents such as magnesium salts and aluminum salts, and surface active agents for reducing drying load and preventing the occurrence of drying mark. Furthermore, the compounds described in L.E. West, Photographic Science and Engineering, Vol. 9, No. 6, (1965), may be added to washing solution. The addition of a chelating agent and antifungal agent to the washing solution is particularly effective. Also, for the washing process, a multistage (e.g., 2 to 5 stages) countercurrent system can be employed for water saving. Also, after or in place of a washing process, a multistage countercurrent stabilizing process as described in Japanese Patent Application (OPI) No. 8543/82 may be employed. In the case of employing a stabilizing process, 2 to 9 countercurrent baths are required. For stabilizing color images formed, various compounds may be added to the stabilizing bath. Examples of such additives include buffers (e.g., borates, metaborates, borax, phosphates, carbonates, potassium hydroxide, sodium hydroxide, aqueous ammonia, monocarboxylic acids, dicarboxylic acids or polycarboxylic acids and formalin for controlling the pH of the photographic layers. In addition, water softeners (inorganic phosphoric acids, aminopolycarboxylic acids, organic phosphoric acids, aminopolyphosphonic acids or phosphonocarboxylic acids), sterilizers (e.g., Proxel, isothiazolone, 4-thiazolylbenzimidazole or halogenated phenolbenzotriazoles), surface active agents, optical whitening agents or hardening agents, may be added, if desired. Also, as an agent for controlling the pH of photographic layers after processing, various ammonium salts such as ammonium chloride, ammonium nitrate, ammonium sulfate, ammonium phosphate, ammonium sulfite or ammonium thiosulfate, can be added to the stabilizer. The invention will be explained in detail with reference to the following examples. EXAMPLE 1 The silver halide emulsions used in this invention were prepared as follows. In the following description, the term "mean grain size" means a mean value of diameters (do) of spheres having the same volume as silver halide grains. Also, the coefficient of deviation is a value obtained by dividing the standard deviation of the diameters (do) by the mean value of the diameters (do). However, when silver halide grains are tabular grains, the coefficient of deviation is defined as the value obtained by dividing the value of the standard deviation of (d) (the diameter of a circle having the same area as the projected area in the case of dispersing the tabular silver halide grains on a plane) by a mean value of (d) and multiplying the quotient by 100. [Preparation of Emulsion A (Coefficient of deviation: 8.5%)] To 900 mℓ of 3% aqueous gelatin were added 2 mℓ of the following "solution a" and 15 mℓ of 1N aqueous H₂SO₄, and further 2.0 g of NaCℓ was dissolved in the mixture. The solution was kept at 65°C and then 589 mℓ of 17% aqueous solution of AgNO₃ and 589 mℓ of a solution containing 21.0 g of KBr and 24.1 g of NaCℓ were added to the mixture under vigorous stirring by a double jet method over a period of 50 min. Furthermore, after removing soluble salts by sedimentation, gelatin was added and re-dispersed and the emulsion was chemically sensitized in optimum condition with sodium thiosulfate to provide Emulsion A. The mean grain size of Emulsion A was 0.70 µm and the silver chloride content was 70 mol%. "Solution a" 1% aqueous solution of the compound [Preparation of Emulsion B (Coefficient of deviation: 9.9%) and Emulsion C (Coefficient of deviation: 9.6%)] By properly reducing the preparation temperature in the case of preparing Emulsion A described above, Emulsion B having a mean grain size of 0.47 µm and Emulsion C having a mean grain size of 0.42 µm were prepared.

Thereafter, 566.4 mℓ of an aqueous AgNO₃ having the above concentration and an aqueous solution of the alkali halides having the above concentration were added to the aforesaid mixture by a double jet method. In this case, the aqueous AgNO₃ was added to the above mixture by accelerated addition such that the added volume per minute v (mℓ/min) became 4.4 + 0.138t t min after the initiation of the addition and also the addition of the aqueous solution of the alkali halides was controlled to maintain the initial pAg. After removing soluble salts by sedimentation, gelatin was added and redispersed therein and the emulsion obtained was chemically sensitized in optimum condition with sodium thiosulfate to provide Emulsion E. In Emulsion E, tabular grains amounted to 80% of the total projected area of the silver halide grains contained, the mean thickness of the tabular grains was 0.14 µm, and the mean aspect ratio thereof was 6. Also, the mean grain size of Emulsion E was 0.70 µm and the silver chloride content was 77 mol%. [Preparation of Emulsion F (Coefficient of deviation: 19.5%)] Emulsion F was obtained by repeating the same procedure as for Emulsion E except that the amounts of NaCℓ and KBr added to 3% aqueous gelatin were properly changed and the pAg was increased. The mean grain size of Emulsion F was 0.70 µm and the silver chloride content thereof was 63 mol%. [Preparation of Emulsion G (Coefficient of deviation: 17.6%) and Emulsion H (Coefficient of deviation: 18.3%)] Emulsion G having a mean grain size of 0.47 µm and Emulsion H having a mean grain size of 0.42 µm were obtained by repeating the same procedure as for Emulsion E except that the preparation temperature was lowered, the added amounts of NaCℓ and KBr to 3% aqueous gelatin were changed, and the pAg was increased.

The solution was kept at 72°C and then 59 mℓ of 17% aqueous solution and 59 mℓ of an aqueous solution containing 5.6 g of KBr and 0.7 g of NaCℓ were added thereto with vigorous stirring by a double jet method over a period of 20 min. Thereafter, 530 mℓ of 17% aqueous AgNO₃ and 530 mℓ of an aqueous solution containing 50.4 g of KBr and 6.2 g of NaCℓ were added thereto by a double jet method over a period of 50 min.

The mean grain size of Emulsion I was 0.70 µm and the silver chloride content was 20 mol%. [Preparation of Emulsion J (Coefficient of deviation: 10.3%)] Emulsion J was prepared by repeating the same procedure as for Emulsion A except that 589 mℓ of an aqueous solution containing 35.1 g of KBr and 17.2 g of NaCℓ was used in place of the aqueous solution of the halides added by the double jet method and the preparation temperature was changed to 68°C.

The silver chloride content of both Emulsion K and Emulsion L was 50 mol%. [Preparation of Emulsion M (Coefficient of deviation: 12.1%)] Emulsion M was prepared by repeating the same procedure as for Emulsion D except that 147 mℓ of an aqueous solution containing 11.4 g of KBr and 3.0 g of NaCℓ was used in place of the aqueous solution of halides added in the 1st step, 442 mℓ of an aqueous solution containing 23.6 g of KBr and 14.2 g of NaCℓ was used in place of the aqueous solution of halides added in the 2nd step, and the preparation temperature was changed to 70°C. The mean grain size of Emulsion M was 0.70 µm and the silver chloride content was 50 mol%. [Preparation of Emulsion N (Coefficient of deviation: 9.5%)] Emulsion N was prepared by repeating the same procedure as for Emulsion A except that 589 mℓ of an aqueous solution containing 7.0 g of KBr and 31.0 g of NaCℓ was used in place of the aqueous solution of halides added by the double jet method and the preparation temperature was changed to 55°C. The mean grain size of Emulsion N was 0.70 µm and the silver chloride content was 90 mol%. Table 1 shows the composition of the light sensitive material. In the above-described preparation of each emulsions, at the time of the end of the chemical sensitization, spectral sensitization was performed by the addition of spectral sensitizing dyes. The kind of silver halide emulsion and the combination of spectral sensitizing dyes with the emulsions are described hereinafter. For each emulsion layer of the color photographic material, the following dyes were used as irradiation preventing dyes. For Green-Sensitive Emulsion Layer : For Red-Sensitive Emulsion Layer : The structural formulae of the compounds used for the couplers were as follows. Thus, Samples (1) to (13) were prepared in the manner described above. The silver halide emulsions and sensitizing dyes used for these samples are shown in Table 2. Comparison 1, Comparison 2, and Comparison 3 shown above as comparison compounds in Table 2 are as follows. Each of Samples (1) to (13) described above was subjected to sensitometric gradation exposure through each of blue filter, green filter and red filter using a sensitometer (Type FWH with color temperature of the light source 3,200°K, made by Fuji Photo Film Co., Ltd.). In this case, the exposure was effected so as to give the exposure of 250 CMS by 0.5 s exposure. Thereafter, the experiments of Processing A and Processing B were conducted using Color Developer (A) or Color Developer (B) as shown below. Each Processing included color development, blix and washing processes and the development time was set to 2 min. The contents of Processings A and B show the difference between Color Developers (A) and (B) and other processing contents are the same in A and B. Processing Step Temperature Time Color Development 36°C 2.0 min Blix 36°C 1.0 min Washing 28-35°C 3.0 min (Preparation of Developer) Color Developer (A): Diethylenetriaminepentaacetic Acid·5Na 2.0 g Benzyl Alcohol 15 mℓ Diethylene Glycol 10 mℓ Na₂SO₃ 2.0 g KBr 0.5 g Hydroxylamine Sulfate 3.0 g 4-Amino-3-methyl-N-ethyl-N-[β-(methanesulfonamido)ethyl]-p-phenylenediamine·Sulfate 5.0 g Na₂CO₃ (monohydrate) 30.0 g Optical Whitening Agent (stilbene series) 1.0 g Water to make 1,000 mℓ (pH 10.2) Color Developer (B): Diethylenetriaminepentaacetic Acid·5Na 2.0 g Na₂SO₃ 2.0 g KBr 0.5 g Hydroxylamine Sulfate 3.0 g 4-Amino-3-methyl-N-ethyl-N-[β-(methanesulfonamido)ethyl]-p-phenylenediamine·Sulfate 5.0 g Na₂CO₃ (monohydrate) 30.0 g Optical Whitening Agent (stilbene series) 1.0 g Water to make 1,000 mℓ (pH 10.2) (Preparation of Blix Solution) (common to Processings A and B) Ammonium Thiosulfate (54% by weight) 150 mℓ Na₂SO₃ 15 g NH₄[Fe(III)(EDTA)] 55 g EDTA·2Na 4 g Water to make 1,000 mℓ (pH 6.9) The results obtained are shown in Table 3 below. The relative sensitivity in Processing B referred to in Table 3 means a relative value of each sensitivity of each light-sensitive emulsion layer of Samples (1) to (13) taking the sensitivity in Processing A as 100. The sensitivity is expressed by a relative value of the reciprocal of the exposure necessary for giving the density of the minimum density plus 0.5. Also, as a measure for knowing the extent of the reduction in the color density due to Processing B, a color density obtained by Processing B at the exposure giving a density of 1.5 in the case of performing Processing A was used. Accordingly, it may be said that as a color photographic magerial gives the color density resulting from Processing B closer to 1.5, it colors more efficiently. Furthermore, the values of fog in the case of performing Processing B are also shown in Table 3 together with those in the case of performing Processing A. From the results of Table 3 above, it can be seen that in the combination of this invention, even when Processing B is performed using no benzyl alcohol, the reduction in relative sensitivity is less, coloring properties are excellent, and the formation of fog is less. Also, it can be seen that when the silver chloride content is less than 60%, the development is delayed and the color density is reduced, which results in reducing the relative sensitivity, while when the silver chloride content is over 80 mol%, the formation of fog is suddenly increased. EXAMPLE 2 By following the same procedure as in Example 1 except that the materials shown in Table 4 below were used, Samples (14) to (18) were prepared. Samples (14) to (18) were exposed and processed as in Example 1 and the photographic properties thereof were evaluated. The photographic properties were evaluated about color density only. The results are shown in Table 5 below. Comparison 4 used as comparison compound in Table 4 above is as follows. Sample No. Layer Color Density in Processing B Remarks (14) B 1.42 Pyrazoloazole G 1.49 R 1.47 (15) B 1.41 Pyrazoloazole G 1.43 R 1.46 (16) B 1.41 Pyrazoloazole G 1.50 R 1.47 (17) B 1.40 5-Pyrazolone G 1.33 R 1.46 (18) B 1.46 Layer 5 Pyrazoloazole Layer 1 G 1.48 R 1.45 From the results shown in Table 5 above, it can be seen that when the magenta coupler of the general formula (V) is used as a magenta coupler to be contained in a green-sensitive emulsion layer, the color density is far increased.
