Description: The present invention relates to a silver halide color photographic material containing a combination of couplers, which is good in color forming properties, improved in color reproducibility and preservability of images, and which is free from destroy in color balance (the multilayered silver halide color photographic material is hereinafter often simply referred to as a "photographic material" or "light-sensitive material"). In silver halide color light-sensitive materials, a light-sensitive layer comprising three kinds of silver halide emulsion layers which have selectively been sensitized to have a sensitivity to blue color, green color and red color, respectively is applied in a multilayered construction onto a support. For example, in a so-called color photographic paper (hereinafter referred to as "color paper"), a red-sensitive emulsion layer, a green-sensitive emulsion layer, and a blue-sensitive emulsion layer are provided usually in that order from the side from which exposure to light is carried out, and a color mixing-preventing or ultraviolet light-absorptive interlayer or protective layer is provided between the respective light-sensitive layers. Furthermore, in a so-called color positive film, a green-sensitive emulsion layer, a red-sensitive emulsion layer, and a blue-sensitive emulsion layer are provided usually in that order from the side that is far from the support, i.e., the side from which exposure to light is carried out. In a color negative film, the layer arrangement is divergent. While it is general that a blue-sensitive emulsion layer, a green-sensitive emulsion layer, and a red-sensitive emulsion layer are provided in that order from the side from which exposure to light is carried out, in light-sensitive materials having two or more emulsion layers which are sensitive to the same color but different in sensitivity, there are light-sensitive materials in which an emulsion layer having a different color sensitivity is disposed between said emulsion layers or a bleachable yellow filter layer, an interlayer, a protective layer, and so on are inserted therebetween. In forming color photographic images, three photographic couplers of yellow, magenta, and cyan are incorporated in light-sensitive layers and, after exposure to light, the resulting light-sensitive material is subjected to color development processing using a so-called color developing agent. The coupling reaction between an oxidation product of an aromatic primary amine and each coupler provides a colored dye. In this reaction, the couplers preferably show a coupling rate as fast as possible to provide a high color density within a limited developing time. Further, formed dyes are required to show bright cyan, magenta or yellow hue with less side absorption to provide color photographic images having good color reproducibility. On the other hand, farmed color photographic images are required to show good preservability under various conditions. In order to satisfy this requirement, it is of importance that formed dyes with different hues show slow color fading or discoloring rate and that the dyes show a discoloring rate as uniform as possible all over the image density region not to make the color balance of the remaining dye image unbalanced. With conventional light-sensitive materials, particularly color papers, cyan dye images are seriously deteriorated by long-time dark fading due to the influence of humidity and heat and, hence, they are liable to undergo a change in color balance, thus being strongly desired to be improved. There has been the tendency that cyan dyes with difficult dark fading show poor hues and are liable to fade and disappear by light. Thus a novel combination of couplers has been demanded. In order to partly solve this problem, there have so far been proposed specific combinations of respective couplers. Some examples thereof are described in, for example, Japanese Patent Publication No. 7344/77, Japanese Patent Application (OPI) Nos. 200037/82, 57238/84, and 160143/84 (the term "OPI" as used herein means an "unexamined published application"). However, these combinations still fail to totally remove various disadvantages that only insufficient color forming properties are obtained; formed dyes have such a poor hue that the color reproduction is adversely affected; color balance of the remaining dye image is changed due to deterioration by, particularly, heat or light; and that the cyan color temporarily disappears by light. As to the phenomenon of temporary disappearance of the cyan color, an improvement of reversibly restoring the cyan color in a dark place is demanded. Further, the techniques as disclosed in Japanese Patent Application (OPI) Nos. 229029/85 and 232550/85 concerned with a combination of specified cyan, magenta and yellow couplers are extremely improved in the above-described various properties as compared with those hitherto known. However, even in this case, though the reproduction of primary colors such as red color and blue color is excellent, faithfulness in reproduction of intermediate colors such as fresh color and reddish purple color is insufficient for a potential reason that the spectral spectrum main absorption wavelength of the magenta image is shifted to the long wavelength side. Also, when color images are preserved under severe conditions of high temperature and high humidity, they involve the drawback that gray-series colors are changed to a reddish color. Research Disclosure, March 1985, pages 134-139, No. 25109, Industrial Oppportunities, P. Kok et al. discloses 6-alkyl or 6-alkenyl-substituted 2,5-diacyl-aminophenol couplers which are capable of forming a cyan dye upon color development of exposed silver halide. It is the object of the present invention to simultaneously solve the above-described problems and, more specifically, to provide a multilayered silver halide color photographic material which has good color forming properties, forms a color photographic image with improved color reproducibility and improved image preservability, and which undergoes no change in color balance particularly when preserved in the dark or exposed to light for a long time. More particularly, it is the object to provide a multilayered silver halide color photographic material which faithfully reproduces intermediate colors and which forms color images with no change in color even when preserved under severe conditions of high temperature and high humidity. The above object of the present invention can be attained by a silver halide color photographic material comprising a support having provided thereon a red-sensitive layer, a green-sensitive layer, and a blue-sensitive layer, in which at least one of the couplers represented by the formulae (I) and/or (II), at least one of the couplers represented by the following formula (III), and at least one of the couplers represented by the following formula (IV) are respectively incorporated in the light-sensitive layers different from each other in color sensitivity: wherein: R₁, R₂, and R₄ each represents a substituted or unsubstituted aliphatic, aromatic or heterocyclic group; R₃, R₅, and R₆ each represents a hydrogen atom, a halogen atom, an aliphatic group, an aromatic group, or an acylamino group or, when taken together, R₃ and R₂ represent the non-metallic atoms necessary for forming a nitrogen-containing 5- or 6-membered ring; R₇ represents an alkoxy group, an aryloxy group, or a heterocyclic oxy group; R₈ represents a substituted or unsubstituted N-phenylcarbamoyl group; Za and Zb each represents methine, substituted methine, or =N-; Y₁, Y₂, Y₃ and Y₄ each represents a hydrogen atom or a group capable of being split off upon coupling reaction with an oxidation product of a developing agent; and n represents 0 or 1, with the proviso that when n represents 0, R₅ is not an acylamino group.

Specific examples of the couplers represented by the formulae (I) to (IV) are shown below. The couplers represented by the formulae (I) and/or (II), (III), and (IV) are each incorporated in a silver halide emulsion layer constituting a light-sensitive layer in an amount of usually from 0.1 to 1.0 mole, preferably from 0.1 to 0.5 mole, per mole of the silver halide. As to the proportions of the respective couplers represented by the formulae (I) and/or (II), (III), and (IV), they are usually incorporated in molar ratios of about 1:0.2 to 1.5:0.5 to 1.5 through ratios outside the ranges may be employed for preparing light-sensitive materials. In the present invention, the above-described couplers may be added to light-sensitive layers by applying various known techniques. Usually, they can be added according to an oil-in-water dispersion process known as an oil protection process. For example, couplers are first dissolved in a single or mixed solvent of high-boiling organic solvents such as phthalates (e.g., dibutyl phthalate or dioctyl phthalate) or phosphates (e.g., tricresyl phosphate or trinonyl phosphate) and low-boiling organic solvents such as ethyl acetate, and then emulsified and dispersed in a gelatin aqueous solution containing a surfactant. Alternatively, water or a gelatin aqueous solution may be added to a coupler solution containing a surfactant, followed by phase inversion to obtain an oil-in-water dispersion. Alkali-soluble couplers may also be dispersed according to a so-called Fischer's dispersion process. The coupler dispersion may be subjected to distillation, noodle water-washing, ultrafiltration, or the like to remove the low-boiling organic solvent and then mixed with a photographic emulsion. In order to introduce the yellow coupler, magenta coupler, and cyan coupler used in the present invention into emulsion layers, high-boiling organic solvents having a boiling point of 160°C or above, such as alkyl phthalates (e.g., dibutyl phthalate or dioctyl phthalate), phosphates (e.g., diphenyl phosphate, triphenyl phosphate, tricresyl phosphate or dioctylbuty phosphate), citrates (e.g., tributyl acetylcitrate), benzoates (e.g., octyl benzoate), alkylamides (e.g., diethyllaurylamide), fatty acid esters (e.g., dibutoxyethyl succinate, dioctyl azelate), phenols (e.g., 2,4-di-t-amylphenol), or low-boiling organic solvents having a boiling point of from 30°C to 150°C, such as lower alkyl acetates (e.g., ethyl acetate or butyl acetate), ethyl propionate, sec-butyl alcohol, methyl isobutyl ketone, β-ethoxyethyl acetate and methylcellosolve acetate may be used alone or in combination as the case demands. Two or more couplers providing the same hue may be selected from the coupler classes represented by the formulae (I) and/or (II), (III), and (IV). In this case, the couplers may be co-emulsified or may separately be emulsified and mixed. Further, anti-fading agents to be described hereinafter may be used in combination with the couplers. Couplers represented by the formula (I) may be mixed with other known cyan couplers, but the effect of the present invention is remarkable when the cyan coupler of the present invention is used in a mixing ratio of 30% or more, preferably 50% or more. Preferable known couplers to be used together are phenolic cyan couplers described in Japanese Patent Publication No. 11572/74. In order to attain the object of the present invention, the weight ratio of the high-boiling organic solvent to the yellow coupler is preferably adjusted to 1.0 or less, particularly from 0.1 to 0.8. The amount of the high-boiling organic solvent for the magenta coupler or cyan coupler is preferably decided by taking into account solubility of the coupler and developability of light-sensitive materials. Usually, the amount of the high-boiling organic solvent ranges from 10% to 300% based on the magenta coupler or cyan coupler. If desired, special couplers other than the couplers used in the present invention represented by the foregoing formulae may be incorporated in the light-sensitive material of the present invention. For example, colored magenta couplers may be incorporated in a green-sensitive emulsion layer to impart a masking effect. Development inhibitor-releasing couplers (DIR couplers) or development inhibitor-releasing hydroquinones may be used in emulsion layers of respective color sensitivities or in layers adjacent thereto. Development inhibitors to be released upon the development provide interlayer effects such as improvement of image sharpness, formation of fine-grained image, improvement of monochromatic saturation. Couplers capable of releasing a development accelerator or a nucleating agent upon development of silver may be added to photographic emulsion layers of the present invention or layers adjacent thereto to obtain effects of improving photographic sensitivity and graininess of color image, and making gradation contrast. In the present invention, a ultraviolet light absorbent may be added to any layer. Preferably, it is incorporated in a layer containing the compound represented by the formula (I) or (II) or a layer adjacent thereto. Ultraviolet light absorbents to be used in the present invention are those compounds which are listed in Research Disclosure, RD No. 17643, VIII, item C, and are preferably benzotriazole derivatives represented by the following formula (XVII): wherein R₂₈, R₂₉, R₃₀, R₃₁, and R₃₂, which may be the same or different, each represents a hydrogen atom or a substituent described with respect to aforesaid R₁, or R₃₁ and R₃₂ may be cyclized each other to form a 5- or 6-membered aromatic ring comprising carbon atoms. Of these, those which may have a substituent or substituents may further be substituted by a substituent or substituents described with respect to R₁. The compound represented by the formula (XVII) may be used alone or in combination of two or more. Typical examples of the ultraviolet light absorbent are illustrated below as UV-1 to UV-19. Processes for synthesizing the compound represented by the foregoing formula (XVII) or examples of other compounds are described in Japanese Patent Publication No. 29620/69, Japanese Patent Application (OPI) Nos. 151149/75 and 95233/79, U.S. Patent 3,766,205, European Patent 0057160 and Research Disclosure, RD No. 22519 (1983). In addition, high molecular weight ultraviolet light absorbents described in Japanese Patent Application (OPI) Nos. 111942/83, 178351/83, 181041/83, 19945/84, and 23344/84, can also be used. A specific example thereof has been shown as UV-20. The low molecular weight ultraviolet light absorbent and the high molecular weight ultraviolet light absorbent may be used in combination. The above-described ultraviolet light absorbent is dissolved in a single or mixed solvent of the high-boiling and low-boiling organic solvents, and the resulting solution is dispersed in a hydrophilic colloid. The amounts of the high-boiling organic solvent and the ultraviolet light absorbent are not particularly limited, but the high-boiling organic solvent is usually used in an amount of from 0% to 300% based on the weight of the ultraviolet light absorbent. Compounds which are liquid at an ordinary temperature are preferably used alone or in combination. The combined use of the ultraviolet light absorbent represented by the foregoing formula (XVII) with a combination of the couplers used in the present invention serves to improve preservability, particularly light fastness, of formed dye images, especially cyan images. This ultraviolet light absorbent may be co-emulsified with the cyan coupler. As to the amount of the ultraviolet light absorbent, it suffices to add it in an amount enough to impart to the cyan dye image stability against light but, when used in a too excess amount, it sometimes causes yellowing of unexposed portions (white background) of the color photographic material. Therefore, the amount is usually selected between 1 x 10⁻⁴ mole/m² and 2 x 10⁻³ mole/m², particularly 5 x 10⁻⁴ mole/m² to 1.5 x 10⁻³ mole/m². In the light-sensitive stratum structure of a usual color paper, the ultraviolet light absorbent is incorporated in at least one (preferably both) of layers adjacent to a cyan coupler-containing red-sensitive emulsion layer. In the case of adding the ultraviolet light absorbent in an interlayer between a green-sensitive layer and a red-sensitive layer, it may be co-emulsified with a color mixing-preventing agent. Where the ultraviolet light absorbent is added to a protective layer, another protective layer may be provided as an outermost layer. A matting agent with an arbitrary particle size, or the like may be incorporated in this protective layer. In order to improve the preservability of formed dye images, particularly yellow and magenta images, various organic and metal complex type anti-fading agents may be used. As the organic anti-fading agents, there are illustrated hydroquinones, gallic acid derivatives, p-alkoxyphenols and p-hydroxyphenols, and, as to dye image stabilizers, stain-preventing agents, and antioxidants, related patents are cited in Research Disclosure, RD No. 17643, items I to J. The metal complex type anti-fading agents are described in, for example, Research Disclosure, RD No. 15162. In order to improve the fastness of the yellow images against heat and light, many compounds belonging to phenols, hydroquinones, hydroxychromans, hydroxycoumarans, hindered amines, and alkyl ethers, silyl ethers, or hydrolyzable precursors thereof may be used. However, compounds represented by the following formulae (XVIII) and (XIX) are effective for simultaneously improving the light fastness and the heat fastness of the yellow images formed from the coupler of the formula (IV): wherein R₄₀ represents a hydrogen atom, an aliphatic group, an aromatic group, a heterocyclic group, or a substituted silyl group or in which R₅₀, R₅₁, and R₅₂, which may be the same or different, each represents an aliphatic group, an aromatic group, an aliphatic oxy group, or an aromatic oxy group, each of which may be substituted by a substituent or substituents acceptable for R₁; R₄₁, R₄₂, R₄₃, R₄₄, and R₄₅, which may be the same or different, each represents a hydrogen atom, an alkyl group, an aryl group, an alkoxy group, a hydroxyl group, a mono- or di-alkylamino group, an imino group, or an acylamino group; R₄₆, R₄₇, R₄₈, and R₄₉, which may be the same or different, each represents a hydrogen atom or an alkyl group; X represents a hydrogen atom, an aliphatic group, an acyl group, an aliphatic or aromatic sulfonyl group, an aliphatic or aromatic sulfinyl group, an oxy radical group, or a hydroxyl group; and A represents a non-metallic atom necessary for forming a 5-, 6-, or 7-membered ring. Examples of the compounds represented by the formula (XVIII) or (XIX) are illustrated below. Processes for synthesizing the compounds represented by the formula (XVIII) or (XIX) and examples of other compounds than those described above are described in British Patents 1,326,889, 1,354,313, and 1,410,846, U.S. Patents 3,336,135 and 4,268,593, Japanese Patent Publication Nos. 1420/76 and 6623/77, and Japanese Patent Application (OPI) Nos. 114036/83 and 5246/84. The compounds represented by the formulae (XVIII) and (XIX) may be used in combination of two or more and, further, may be used in combination with conventionally known anti-fading agents. The amounts of the compounds represented by the formulae (XVIII) and (XIX) vary depending upon the kind of the yellow coupler to be used together, but the intended object can be attained by using the compounds in amounts of from 0.5 to 230 wt%, preferably from 2 to 150 wt%, based on the yellow coupler. It is preferable to co-emulsify them with the yellow coupler represented by the formula (IV). The aforementioned various dye stabilizers, stain-preventing agents, or antioxidants are effective for improving the preservability of magenta color dyes of the coupler represented by the formula (III). Compounds represented by the following formulae (XX) to (XXVII) are particularly effective for greatly improving the light fastness. In the above formulae (XX) to (XXVII), R₆₀ is the same as defined for R₄₀ in the formula (XVIII); R₆₁, R₆₂, R₆₃, R₆₄, and R₆₅, which may be the same or different, each represents a hydrogen atom, an aliphatic group, an aromatic group, a mono- or di-alkylamino group, an aliphatic or aromatic thio group, an acylamino group, an aliphatic or aromatic oxycarbonyl group or -OR₄₀, or R₆₀ and R₆₁, or R₆₁ and R₆₂, may be taken together to form a 5- or 6-membered ring; X represents a divalent linking group; R₆₆ and R₆₇, which may be the same or different, each represents a hydrogen atom, an aliphatic group, an aromatic group, or a hydroxyl group; R₆₈ and R₆₉, which may be the same or different, each represents a hydrogen atom, an aliphatic group, or an aromatic group; R₇₀ represents an aliphatic group or an aromatic group; or R₆₆ and R₆₇ may be taken together to form a 5- or 6-membered ring; R₆₈ and R₆₉, or R₆₉ and R₇₀, may be taken together to form a 5- or 6-membered ring; M represents Cu, Co, Ni, Pd, or Pt; when the substituent R₆₁ to R₇₀ are aliphatic or aromatic groups, they may be substituted by those substituents which are acceptable for R₁; n represents an integer of from 0 to 6; and m represents an integer of from 0 to 4, with n and m being the numbers of R₆₂ and R₆₁, respectively, and, when they represent 2 or more, R₆₂ or R₆₁ may be the same or different. In the formulae (XXIV) and (XXVI), preferable typical examples of X are wherein R₇₁ represents a hydrogen atom or an alkyl group. In the formula (XXV), R₆₁ preferably represents a group capable of forming a hydrogen bond. Those compounds wherein at least one of R₆₂, R₆₃, and R₆₄ represents a hydrogen atom, a hydroxyl group, an alkyl group, or an alkoxy group are preferable, and the substituents R₆₁ to R₆₈ preferably represent substituents respectively containing 4 or more carbon atoms in the whole. Specific examples of the compounds represented by the formulae (XX) to (XXVII) are shown below. Processes for synthesizing these compounds and examples of other compounds are described in U.S. Patents 3,336,135, 3,432,300, 3,573,050, 3,574,627, 3,700,455, 3,764,337, 3,935,016, 3,982,944, 4,254,216, and 4,279,990; British Patents 1,347,556, 2,062,888, 2,066,975, and 2,077,455; Japanese Patent Application (OPI) Nos. 152225/77, 17729/78, 20327/78, 145530/79, 6321/80, 21004/80, 24141/83, 10539/84, and 97353/85; and Japanese Patent Publication Nos. 31625/73 and 12337/79. Of the anti-fading agents to be used in the present invention, those compounds which are represented by the formulae (XX) to (XXIV) are added in amounts of from 10 to 200 mole%, preferably from 30 to 100 mole%, based on the magenta coupler used in the present invention. On the other hand, the compound represented by the formula (XXV) is added in an amount of from 1 to 100 mole%, preferably from 5 to 40 mole%, based on the magenta couplers used in the present invention. These compounds are preferably co-emulsified with the magenta coupler. As techniques for preventing color fading, a technique of surrounding a dye image by an oxygen barrier layer composed of a substance with a low oxygen permeation ratio is disclosed in, for example, Japanese Patent Application (OPI) Nos. 11330/74 and 57223/75, and a technique of providing a layer having an oxygen permeation ratio of 20 ml/m².h.atom or less in the support side of a color image-forming layer of a color photographic material is disclosed in Japanese Patent Application (OPI) No. 85747/81. These techniques can be applied to the present invention. Various silver halides may be used in the silver halide emulsion layer of the material of the present invention. For example, there are illustrated silver chloride, silver bromide, silver chlorobromide, silver iodobromide and silver chloroiodobromide, with silver iodobromide containing from 2 to 20 mole% silver iodide and silver chlorobromide containing from 10 to 50 mole% silver bromide being preferable. Silver halide grains are not limited as to crystal form, crystal structure, grain size or grain size distribution. Crystals of silver halide may be either of normal crystal or twin, and may be any of hexahedron, octahedron, and tetradecahedron. In addition, tabular grains having a thickness of 0.5 µm or less, a diameter of at least 0.6 µm, and an average aspect ratio of 5 or more, as described in Research Disclosure, RD No. 22534, may be used. The crystal structure may be uniform or of a structure wherein the inner portion and the outer portion are different from each other in halide composition, or may be stratiform. Further, silver halide crystals different from each other in composition may be conjuncted by epitaxial conjunction or silver halide crystals may comprise a mixture of grains of various crystal forms. In addition, silver halide grains of the type forming a latent image mainly on the surface thereof and grains of the type forming a latent image mainly within them may be used. As to grain size of silver halide grains, fine grains having a grain size of not more than 0.1 µm and large-sized grains having a grain size of up to 3 µm in projected area diameter may be used. A monodispersed emulsion having a narrow grain size distribution and a polydispersed emulsion having a broad distribution may be used. These silver halide grains may be prepared according to processes conventionally employed in the art. The aforementioned silver halide emulsion may be sensitized by ordinarily employed chemical sensitization process, i.e., a sulfur sensitization process, a noble metal sensitization process, or a combination thereof. Further, the silver halide emulsion used in the present invention may be provided with color sensitivity in desired light-sensitive wavelength region by using sensitizing dyes. Dyes to be advantageously used in the present invention include methine dyes and styryl dyes, such as cyanines, hemicyanines, rhodacyanines, merocyanines, oxonols and hemioxonols. These dyes may be used alone or as a combination of two or more. As supports to be used in the present invention, any of transparent supports such as polyethylene terephthalate and cellulose triacetate and reflective supports as described hereinafter may be used, with the latter reflective supports being preferable. As reflective supports, there are illustrated, for example, baryta paper, polyethylene-coated paper, polypropylene synthetic paper, transparent supports having provided thereon a reflective layer or having a reflective substance, such as glass sheet, polyester films (e.g., polyethylene terephthalate, cellulose triacetate, or cellulose nitrate), polyamide film, polycarbonate film and polystyrene film. These supports may appropriately be selected depending upon the purpose for use. Blue-sensitive emulsions, green-sensitive emulsions and red-sensitive emulsions used in the present invention are those spectrally sensitized to have color sensitivities using methine dyes or other dyes, respectively. Examples of dyes which can be used include cyanine dyes, merocyanine dyes, complex cyanine dyes, complex merocyanine dyes, holopolar cyanine dyes, hemicyanine dyes, styryl dyes, and hemioxonol dyes. Of these dyes, cyanine dyes, merocyanine dyes, and complex merocyanine dyes are particularly useful. To these dyes are applicable as a basic heterocyclic nucleus any of nuclei conventionally employed for cyanine dyes. That is, there are illustrated a pyrroline nucleus, an oxazoline nucleus, a thiazoline nucleus, a pyrrole nucleus, an oxazole nucleus, a thiazole nucleus, a selenazole nucleus, an imidazole nucleus, a tetrazole nucleus and a pyridine nucleus; nuclei where alicyclic hydrocarbon rings are fused on the foregoing nuclei; and nuclei where aromatic hydrocarbon rings are fused on the foregoing nuclei, e.g., an indolenine nucleus, a benzindolenine nucleus, an indole nucleus, a benzoxazole nucleus, a naphthoxazole nucleus, a benzothiazole nucleus, a naphthothiazole nucleus, a benzoselenazole nucleus, a benzimidazole nucleus, and a quinoline nucleus. These nuclei may be substituted on a carbon atom. To merocyanine dyes or complex merocyanine dyes, 5-or 6-membered heterocyclic nuclei such as a pyrazolin-5-one nucleus, a thiohydantoin nucleus or a 2-thiobarbituric acid nucleus may be applied as a nucleus having a ketomethylene structure. These sensitizing dyes may be used alone or in combination thereof. Combinations of sensitizing dyes are, in particular, often used for the purpose of supersensitization. Typical examples thereof are described in U.S. Patents 2,688,545, 2,977,229, 3,397,060, 3,522,052, 3,527,641, 3,617,293, 3,638,964, 3,666,480, 3,672,898, 3,679,428, 3,703,377, 3,769,301, 3,814,609, 3,837,862, and 4,026,707; British Patents 1,344,281 and 1,507,803; Japanese Patent Publication Nos. 4936/68 and 12375/78; and Japanese Patent Application (OPI) Nos. 110618/77 and 109925/77. Dyes which do not themselves have a sensitizing function or substances which do not substantially absorb a visible light but exhibit supersensitization may be incorporated in emulsions in combination with the sensitizing dye. In the color photographic light-sensitive material of the present invention, a subsidiary layer such as a subbing layer, an interlayer, and a protective layer can be provided in addition to the above-described constituting layers. Further, a second ultraviolet light absorbing layer may be provided between a red-sensitive silver halide emulsion layer and a green-sensitive silver halide emulsion layer, if desired. In such a ultraviolet light absorbing layer, the above-described ultraviolet light absorbents are preferably used, but other known ultraviolet light absorbents may be employed. Gelatin is advantageously used as binders or protective colloids for photographic emulsions, but other hydrophilic colloids can also be used. For example, it is possible to use proteins such as gelatin derivatives, graft polymers of gelatin and other polymers, albumin, or casein, saccharose derivatives such as cellulose derivatives such as hydroxyethyl cellulose, carboxymethyl cellulose, or cellulose sulfate, sodium alginate or starch derivatives, and synthetic hydrophilic high molecular weight substances such as homo-or copolymers, e.g., as polyvinyl alcohol, polyvinyl alcohol partial acetal, poly-N-vinyl pyrrolidone, polyacrylic acid, polymethacrylic acid, polyacrylamide, polyvinyl imidazole, or polyvinyl pyrazole. As gelatin, not only lime-processed gelatin but also acid treated gelatin and enzyme treated gelatin as described in Bull. Soc. Sci. Phot. Japan, No. 16, page 30 (1966) may be used. Further, hydrolyzed products or enzymatic decomposition products of gelatin can also be used. In the light-sensitive material of the present invention, the photographic emulsion layers and other hydrophilic colloid layers may contain whitening agents such as stilbene type, triazine type, oxazole type, or coumarine type whitening agents. They may be water-soluble, and water-insoluble whitening agents may be used in the form of a dispersion. Specific examples of suitable fluorescent whitening agents are described in U.S. Patents 2,632,701, 3,269,840, and 3,359,102; British Patents 852,075 and 1,319,763; and Research Disclosure, Vol. 176, RD No. 17643, page 24, left column, lines 9 to 36, "Brighteners" (December, 1978). In the light-sensitive material of the invention, when dyes, ultraviolet light absorbents, and the like are incorporated into the hydrophilic colloid layers, they may be mordanted with cationic polymers, etc. For example, polymers as described in British Patent 685,475; U.S. Patents 2,675,316, 2,839,401, 2,882,156, 3,048,487, 3,184,309, and 3,445,231; West German Patent Application (OLS) No. 1,914,362; and Japanese Patent Application (OPI) Nos. 47624/75 and 71332/75 can be used. The light-sensitive material of the present invention may contain therein hydroquinone derivatives, aminophenol derivatives, gallic acid derivatives, ascorbic acid derivatives, etc., as color fog preventing agents. Specific examples thereof are described in U.S. Patents 2,360,290, 2,336,327, 2,403,721, 2,418,613, 2,673,314, 2,701,197, 2,704,713, 2,728,659, 2,732,300, and 2,735,765; Japanese Patent Application (OPI) Nos. 92988/75, 92989/75, 93928/75, 110337/75, and 146235/77; and Japanese Patent Publication No. 23813/75. To the color photographic light-sensitive material of the present invention, various photographic additives known in this field, for example, stabilizers, antifoggants, surface active agents, couplers other than the present invention, filter dyes, irradiation preventing dyes or developing agents can be added in addition to the above described compounds, if desired. Further, to silver halide emulsion layers or other hydrophilic colloid layers, substantially light-insensitive fine grain silver halide emulsions (for example, a silver chloride, silver bromide, or silver chlorobromide emulsion having an average particle size of 0.20 µm or less) may be added, if desired. Color developing solutions used in the present invention are preferably alkaline aqueous solutions containing aromatic primary amine color developing agents as main components. Typical examples of the color developing agents include 4-amino-N,N-diethylaniline, 3-methyl-4-amino-N,N-diethylaniline, 4-amino-N-ethyl-N-β-hydroxyethylaniline, 3-methyl-4-amino-N-ethyl-N-β-hydroxyethylaniline, 3-methyl-4-amino-N-ethyl-N-β-methanesulfonamidoethylaniline and 4-amino-3-methyl-N-ethyl-N-β-methoxyethylaniline. The color developing solutions can further contain pH buffering agents such as sulfites, carbonates, borates, or or phosphates of alkali metals, development inhibitors or antifogging agents such as bromides, iodides, or organic antifogging agents. In addition, if desired, the color developing solutions can also contain water softeners; preservatives such as hydroxylamine; organic solvents such as benzyl alcohol or diethylene glycol; development accelerators such as polyethylene glycol, quaternary ammonium salts or amines; dye forming couplers; competing couplers; fogging agents such as sodium borohydride; auxiliary developing agents such as 1-phenyl-3-pyrazolidone; viscosity-imparting agents; polycarboxylic acid type chelating agents as described in U.S. Patent 4,083,723; antioxidants as described in West German Patent Application (OLS) No. 2,622,950. After color development, the photographic emulsion layer is usually subjected to a bleaching processing. This bleach processing may be performed simultaneously with a fixing processing, or may be performed independently. Bleaching agents which can be used include compounds of polyvalent metals, for example, iron (III), cobalt (III), chromium (VI), and copper (II), peracids, quinones and nitroso compounds. For example, ferricyanides; dichromates; organic complex salts of iron (III) or cobalt (III), for example, complex salts of aminopolycarboxylic acids (e.g., ethylenediaminetetraacetic acid, nitrilotriacetic acid or 1,3-diamino-2-propanoltetraacetic acid) or organic acids (e.g., citric acid, tartaric acid or malic acid); persulfates; permanganates; nitrosophenol, can be used. Of these compounds, potassium ferricyanide, iron (III) sodium ethylenediaminetetraacetate, and iron (III) ammonium ethylenediaminetetraacetate are particularly useful. Ethylenediaminetetraacetic acid iron (III) complex salts are useful in both an independent bleaching solution and a mono-bath bleach-fixing solution. After the color development or bleach-fixing processing step, washing with water may be conducted. The color development can be practiced at an appropriate temperature ranging from 18 to 55°C. The color development is conducted preferably at 30°C or higher and particularly at 35°C or higher. The time necessary for development is in a range from about 1 min to about 3.5 min and the shorter time is preferred. For continuous development processing, it is preferred to practice replenishing of processing solutions. A replenisher of 160 ml or less per m² and preferably 100 ml or less per m² of the photographic materials to be processed may be employed. The concentration of benzyl alcohol in the developing solution is preferably 5 ml or less per l thereof. The bleach-fixing can be practiced at an appropriate temperature ranging from 18 to 50°C, and preferably at 30°C or higher. When the bleach-fixing is conducted at 35°C or higher, it is possible to shorten the processing time to a range of 1 min or less and to reduce an amount of replenisher to be added. The time necessary for washing with water after color development or bleach-fixing is usually within 3 min. The dyes formed are degradated not only with light, heat or temperature but also by mold during preservation. Since cyan color images are particularly degradated by mold, it is preferred to employ antimolds. Specific examples of antimolds include 2-thiazolylbenzimidazoles as described in Japanese Patent Application (OPI) No. 157244/82. Antimolds can be incorporated into the light-sensitive material or may be added thereto from outside during development processing. Antimolds can be included in photographic materials in any appropriate steps as far as the photographic materials after processing contain them. The present invention will be explained in greater detail with reference to the following examples. EXAMPLE 1 A multilayered color photographic printing paper comprising a paper support, both surfaces of which were laminated with polyethylene, and having provided thereon the stratum structure shown in Table 1 was prepared. Coating solutions were prepared as follows. Preparation of a coating solution for forming a first layer: 10 ml of ethyl acetate and 4 ml of solvent (c) were added to 10 g of yellow coupler (a) and 23 g of color image stabilizer (b) to dissolve, and the resulting solution was emulsified and dispersed in 90 ml of a 10% gelatin aqueous solution containing 5 ml of 10% sodium dodecylbenzenesulfonate. On the other hand, 90 g of a blue-sensitive emulsion was prepared by adding the blue-sensitive dye shown below to a silver chlorobromide emulsion (containing 80 mole% of silver iodide and 70 g/kg of silver) in an amount of 4.0 x 10⁻⁴ mole per mole of silver chlorobromide. The emulsion dispersion and the emulsion were mixed to prepare a solution, and gelatin was added thereto to adjust the concentrations of the ingredients to the composition shown in Table 1. Thus, a coating solution for forming a first layer was prepared. Coating solutions for the second layer to the seventh layer were prepared in the sane manner as the coating solution for the first layer. 2-Hydroxy-4,6-dichloro-s-triazine sodium salt was used as a gelatin hardener for each layer. As spectral sensitizing agents, the following ones were used.

Green-sensitive emulsion layer: Red-sensitive emulsion layer: The structural formulae of the couplers used in this Example are as follows. (a) Yellow coupler: (b) Image stabilizer: (c) Solvent: (d) Color mixing-preventing agent: (e) Magenta coupler: (f) Image stabilizer: (g) Solvent: 2:1 (by weight) mixture of (h) Ultraviolet light absorbent: 1:5:3 (by mole) mixture of and (i) Color mixing-preventing agents: (j) Solvent: (k) Cyan coupler: 2:1 (by mole) mixture of and (l) Image stabilizer: 1:3:3 (by mole) mixture of (m) Solvent: After balancing surface tension and viscosity of the coating solutions for forming the first to seventh layers, they were simultaneously coated to prepare a multilayered silver halide photographic material. This color photographic material was referred to as Sample 101. Then, Samples 102 to 104 were prepared in the same manner except for the changes as shown in Table 2. After being subjected to gradation exposure for sensitometry, these samples were developed according to the following processing steps. Processing Step Temperature Time Color development 33°C 3 min 30 s Bleach-fixing 33°C 1 min 30 s Washing with water 24 to 34°C 3 min Drying 80°C 1 min The formulations of the processing solutions were as shown below.

Sensitivities, fogs, and peak wavelengths of spectral reflection of these samples are shown in Table 3. All of Samples 101 to 104 immediately after being processed showed a fog of 0.09 in terms of magenta density. Fogs and densities of these samples after being preserved at 35°C and 80% RH (relative humidity) for 3 days and of these samples after being preserved at 80°C and 70% RH for 14 days are also shown in Table 3. Fogs under the conditions of 80°C and 70% RH were measured in terms of yellow density, and fogs under the other conditions were measured in terms of magenta color density. The sensitivities were presented as a relative value of an exposure amount giving a density of 0.8, taking that of Sample 101 as 100. The densities after being preserved were measured at a point where the density before the preservation was 1.0. After preserving for 3 days at 35°C and 80% RH, no changes were observed in the gradation portion, whereas the fog (Dmin) was changed. With the comparative sample, the fog was increased, whereas with the samples of the present invention, the fog was not changed at all or only slightly changed. After preserving for 14 days at 80°C and 70% RH, a change in density was observed even in the gradation portions. However, the comparative sample underwent a serious increase in density, whereas the samples of the present invention underwent only a small increase. As to the fog of yellow density (stain with a magenta coupler), the samples of the present invention underwent less increase. As to the change in cyan density and change in yellow density after the preservation at 80°C and 70% RH for 14 days, the cyan density was changed from 1 to 0.94, and the yellow density from 1 to 1.02. As to the change in color balance from neutral gray, the comparative sample underwent a serious change to a red to magenta tint, whereas the samples of the present invention underwent a slight change to a red tint. Thus, it is seen that the samples of the present invention showed excellent results with respect to color image preservability, particularly change in color balance. Further, color reproducibility was examined by preparing a print with neutral gray from a color negative-working film on which a Macbeth color rendering chart had been photographed, using each of the samples of the present invention. In the print prepared from the comparative sample, saturation of a red patch was insufficient, and a magenta patch had a cyan tint. With the prints prepared from the samples of the present invention, Samples 102 and 103 provided extremely high saturation, though a red patch had a slightly orange tint, thus showing good color reproducibility. Sample 104 showed the best color reproducibility for a red patch and a magenta patch. Thus, it is seen that the samples of the present invention show excellent properties with respect to color reproducibility as well. EXAMPLE 2 Samples 105 to 108 were prepared in the same manner as Samples 101 and 104 of Example 1 except for the change shown in Table 4 and were subjected to the same preservation test as in Example 1 of preserving at 80°C and 70% RH for 14 days. Sample Content of the change from Sample 101 105 Cyan coupler (k) in the 5th layer of Sample 101 was replaced by an equimolar amount of the following cyan coupler C-1 106 Cyan coupler (k) in the 5th layer of Sample 104 was replaced by an equimolar amount of the following cyan coupler C-1 107 Cyan coupler (k) in the 5th layer of Sample 101 was replaced by an equimolar amount of (k₁) alone. 108 Cyan coupler (k) in the 5th layer of Sample 104 was replaced by an equimolar amount of (k₁) alone. The changes in magenta density and yellow density of these samples were the same as for Samples 101 and 104, and change in cyan density was as follows. Samples 105 and 106 underwent a considerable change from neutral gray to a red tint. However, Sample 106 underwent a less shift from gray due to no increase in magenta density. Samples 107 and 108 showed a slightly red tint. However, like the relation between Sample 101 and Sample 104 in Example 1, Sample 108 underwent a less change in gray balance, thus was found to be excellent.
