Description: FIELD OF THE INVENTION The present invention relates to silver halide color photographic materials, and particularly to a silver halide color photographic material improved in preservability of the color image by using an epoxy compound that is sparingly water-soluble. More particularly the present invention relates to a silver halide color photographic material improved in fastness of the color image to light, heat, humidity, or acids and prevented from increasing stain with long-term storage by using the above compound. BACKGROUND OF THE INVENTION When color photographic materials are stored as records semipermanently, the extent of light-fading and dark-fading should be suppressed as much as possible and the color balance of three-color-fading among the yellow, magenta, and cyan dye images should be retained as in the initial state. However, the extent of light-fading and dark-fading of the yellow, magenta, and cyan dye images differs from dye image to dye image, and after long-term storage, the color balance of three-color-fading is lost and the image quality of the dye images deteriorates. Dark-fading of the yellow dye image and the cyan dye image in an environment high in humidity is greater than that of the magenta dye image, and the color balance is lost considerably in some cases. Further, when the photographic material is stored under such conditions, mold occurs on the photographic material surface and the cyan dye image and the yellow dye image are faded extremely by organic acids (e.g., acetic acid, citric acid, tartaric acid, and gluconic acid) secreted from the fungi, thereby leaving red spots in the image, for example, of a color print. Such a defect is often found in areas high in both temperature and humidity, for example in southern district of Japan (e.g., Okinawa and Shikoku), and in the case of important photographs which are desired to be preserved as records, such as wedding photographs, although a measure of laminating the photographs is taken, not only is the operation complicated and laborious, but deterioration of the image quality cannot be obviated anyway. Even if mold does not occur, when the pH of the surface of the produced photographic image is low due to the type or scatter of conditions of the development processing, bleach-fix processing, or stabilization processing, fading of the cyan dye image and the yellow dye image is also promoted. To solve such problems, with respect to cyan dye images, for example, JP-B ("JP-B" means examined Japanese patent publication) No. 45017/1983 and JP-A ("JP-A" means unexamined published Japanese patent application) Nos. 75447/1987, 129853/1987, 172353/1987, 196657/1987, and 21447/1989, and with respect to yellow dye images, for example, JP-A Nos. 50048/1989, 50049/1989, and 4041/1986, disclose the use of cyclic ether compounds or epoxy-group-containing compounds, and although it is recognized that these compounds have an effect to a certain extent on the improvement of fastness to dark-fading and acid-fading, the improvement is still unsatisfactory, and in some cases there are injurious effects that fading or insufficient color restoration occurs due to the leuco dye formation of a cyan dye formed when the photographic material is processed in a bleach-fix bath containing an exhausted solution. The cyan dye image obtained from phenol couplers having as a ballasting group a straight-chain or branched alkyl group, described in JP-A No. 39045/1986, is excellent in fastness to light and heat, but it has defects that it is poor in fastness to the above-mentioned acids and the unexposed part (white background) is colored cyan with long-term storage. A method for solving the latter problem by additionally using a certain epoxy compound is described in JP-A No. 21447/1989, but the method is insufficient for improvement in the former problem: acid-fading. SUMMARY OF THE INVENTION An object of the present invention is to provide a silver halide photographic material that is improved in fastness to dark-fading, light-fading, and acid-fading of the image dye with long-term storage, so that it can form a dye image that exhibits excellent image preservability. Another object of the present invention is to provide a silver halide color photographic material that is improved, in particular, in fastness to dark-fading, light-fading, and acid-fading of the cyan dye image with long-term storage, and whose unexposed part, i.e., white background, is not colored cyan. Other and further objects, features, and advantages of the invention will appear more fully from the following description.

The cyan coupler represented by formula (IVa) may be used in combination with other cyan couplers represented by formula (IV). Herein the term "sparingly water-soluble" means that the solubility in water at 25°C is 10% or below, and the epoxy compound of the present invention is used by emulsifying and dispersing it together with or separately from the coupler into a hydrophilic binder, such as an aqueous gelatin solution using a surface-active agent. At that time, a high-boiling organic solvent that has a boiling point of 160°C or over and that is sparingly soluble in water, or a low-boiling auxiliary organic solvent, may be used. Although the coupler and the epoxy compound that is sparingly soluble in water may be added to separate layers, preferably they are added to the same layer, in particular to the same oil droplets. However, with respect to cyan couplers, if a cyan coupler represented by formula (IVa) is used, the epoxy compound that is sparingly water-soluble is preferably added to a nonphotosensitive hydrophilic layer separate from the layer containing the cyan coupler, for example to an intermediate layer (e.g., between a cyan coupler-containing layer and a magenta coupler-containing layer, or between a magenta coupler-containing layer and a yellow coupler-containing layer), to a layer between the undermost photosensitive silver halide emulsion layer and a base, to a surface-protective layer, or to a layer between a surface-protective layer and an uppermost photosensitive silver halide emulsion layer, in view of the prevention of the light-fading of the cyan dye. Examples of the compounds represented by formulae (I), (II), and (III) that can be used in the present invention are specifically shown below, but the present invention is not restricted to them. In the above structural formulae, the variable x is a real number and may be any real number in the range of 0 to 20. The reason why x and y are not necessarily an integer is that epoxy compounds having different integral values are mixed in a certain ratio and the variable x is the average value of the different integral values. These epoxy compounds may be used alone or as a mixture of two or more, or they may be used in combination, with a high-boiling organic solvent and/or a water-soluble and organic solvent-soluble polymer. Preferable examples of the high-boiling organic solvent and the polymer are those disclosed in JP-A No. 537/1989. The above-mentioned epoxy resin used in the present invention is, for example, one obtained by reacting bisphenol A with epichlorohydrin in the presence of caustic soda (Naoshiro Ooishi, et al., Purasuchikku Zairyo Koza (5), Epokishi Jushi, Nikkan Kogyo Shinbunsha). As this epoxy resin, a commercially available one can be used, for example, Epikote (manufactured by Shell International Chemicals Corp.), Araldite (manufactured by Ciba Ltd.), Bakelite (manufactured by UCC), and DER (manufactured by Dow Chemical Co.) which are trade names. Examples of the cyan coupler represented by formula (IV) are described in detail in JP-A No. 537/1984. Specific examples of the compound are shown below, but compounds of the present invention are not restricted to them. Each ratio of x/y/z or x/y shown below is represented in weight ratio. In particular, specific examples of the cyan coupler represented by formula (IVa) include the below-mentioned IV-1 to IV-20, however the present invention is not restricted to them. Compound IV-3 is identical to C-11 mentioned above, IV-4 is identical to C-12 mentioned above, and IV-8 is identical to C-10 mentioned above. Examples of the yellow coupler represented by formula (V) are described, for example, in detail in JP-A Nos. 50049/1989 and 50048/1989. Specific examples of the compound are shown below, but compounds of the present invention are not restricted to them. The amount of the epoxy compounds represented by formulae (I) to (III) to be added is generally 0.001 to 10 g, preferably 0.01 to 5 g, and more preferably 0.03 to 1 g, per m 2 . The amount of the coupler compound represented by formula (IV) or (V) to be added is generally 0.1 to 1.0 mol, preferably 0.1 to 0.5 mol, per mol of the silver halide to be contained in a silver halide emulsion layer constituting the photosensitive layer. According to one embodiment in practicing the present invention the photographic material of this invention is subjected to such a rapid color development processing as the color development processing time is 30 sec or less. In the embodiment it is preferable to use a silver halide emulsion comprising 90 mol% or more of silver chloride. Color development processing time is more preferably 25 sec or less, and particularly preferably 20 sec or less. Total processing time including a rapid color development is preferably 180 sec or less, more preferably 120 sec or less, and particularly preferably 90 sec or less. Further, the color photographic material of the present invention is preferably one that shows 3.0 mmol/m 2 or less of alkali consumption. The alkali consumption is an indication of the amount of acidic components contained in the photographic material, which amount influences a development speed. The alkali consumption of photographic material is obtained by the following measuring method and calculation. As the first step for calculating an alkali consumption, a definite area (concretely, 1 square meter) of photographic material is sampled and is separated into a support and coating layers. As an ordinary support is formed by laminating polyethylene film on a paper, separation is effected between layers. Next, the coating layer part is divided finely and then is dispersed in a definite amount (concretely, 100 ml) of water. Then, the dispersion is titrated by an aqueous alkali solution (concretely, 0.1 N potassium hydroxide solution). The alkali consumption is defined as mmol of potassium hydroxide required to reach pH 10.0 from pH 6.0 in the above titration. When a support contains acid components but cannot been separated as described above, the evaluation is done by subtracting the alkali consumption for support alone. This alkali consumption is influenced by gelatin that is a hydrophilic binder in a photographic material and other organic compounds. The alkali consumption is preferably 3.0 mmol/m 2 or less, more preferably 2.8 mmol/m 2 or less, further more preferably 2.6 mmol/m 2 and particularly preferably 1.9 mmol/m 2 or less. The color photographic material of the present invention can be constituted by applying at least each of a blue-sensitive silver halide emulsion layer, a green-sensitive red-sensitive silver halide emulsion layer, and a silver halide emulsion layer on a base. For common color print papers, the above silver halide emulsion layers are applied in the above-stated order on the base, but the order may be changed. Color reproduction by the subtractive color process can be performed by incorporating, into these photosensitive emulsion layers, silver halide emulsions sensitive to respective wavelength ranges, and so-called colored-couplers capable of forming dyes complementary to light to which the couplers are respectively sensitive, that is, capable of forming yellow complementary to blue, magenta complementary to green, and cyan complementary to red. However, the constitution may be such that the photosensitive layers and the color formed from the couplers do not have the above relationship. As the silver halide emulsion used in the present invention, one comprising silver chlorobromide or silver chloride of silver chloride content 90 mol% or over and being substantially free from silver iodide can be preferably used. Herein the term "substantially free from silver iodide" means that the silver iodide content is 1 mol% or below, and preferably 0.2 mol% or below. Although the halogen compositions of the emulsions may be the same or different from grain to grain, if emulsions whose grains have the same halogen composition are used, it is easy to make the properties of the grains homogeneous. With respect to the halogen composition distribution in a silver halide emulsion grain, for example, a grain having a so-called uniform-type structure, wherein the composition is uniform throughout the silver halide grain, a grain having a so-called layered-type structure, wherein the halogen composition of the core of the silver halide grain is different from that of the shell (which may comprises a single layer or layers) surrounding the core, or a grain having a structure with nonlayered parts different in halogen composition in the grain or on the surface of the grain (if the nonlayered parts are present on the surface of the grain, the structure has parts different in halogen composition joined onto the edges, the corners, or the planes of the grain) may be suitably selected and used. To secure high sensitivity, it is more advantageous to use either of the latter two than to use grains having a uniform-type structure, which is also preferable in view of the pressure resistance. If the silver halide grains have the above-mentioned structure, the boundary section between parts different in halogen composition may be a clear boundary, or an unclear boundary, due to the formation of mixed crystals caused by the difference in composition, or it may have positively varied continuous structures. As to the silver halide composition of these silver chlorobromide emulsion, the ratio of silver bromide/silver chloride can be selected arbitrarily. That is, the ratio is selected from the broad range in accordance with the purpose, but the ratio of silver chloride in a silver chlorobromide is preferably 2% or more. Further in the photographic material suitable for a rapid processing a emulsion of high silver chloride content, so-called a high-silver-chloride emulsion may be used preferably. The content of silver chloride of the high-silver-chloride emulsion is preferably 90 mol% or more, more preferably 95 mol% or more. In these high-silver-chloride emulsions, the structure is preferably such that the silver bromide localized layer in the layered form or nonlayered form is present in the silver halide grain and/or on the surface of the silver halide grain as mentioned above. The silver bromide content of the composition of the above-mentioned localized layer is preferably at least 10 mol%, and more preferably over 20 mol%. The localized layer may be present in the grain, or on the edges, or corners of the grain surfaces, or on the planes of the grains, and a preferable example is a localized layer epitaxially grown on each corner of the grain. On the other hand, for the purpose of suppressing the lowering of the sensitivity as much as possible when the photographic material undergoes pressure, even in the case of high-silver-chloride emulsions having a silver chloride content of 90 mol% or over, it is preferably also practiced to use grains having a uniform-type structure, wherein the distribution of the halogen composition in the grain is small. In order to reduce the replenishing amount of the development processing solution, it is also effective to increase the silver chloride content of the silver halide emulsion. In such a case, an emulsion whose silver chloride is almost pure, that is, whose silver chloride content is 98 to 100 mol%, is also preferably used. The average grain size of the silver halide grains contained in the silver halide emulsion used in the present invention (the diameter of a circle equivalent to the projected area of the grain is assumed to be the grain size, and the number average of grain sizes is assumed to be an average grain size) is preferably 0.1 to 2 µm. Further, the grain size distribution thereof is preferably one that is a so-called monodisperse dispersion, having a deviation coefficient (obtained by dividing the standard deviation of the grain size by the average grain size) of 20% or below, and desirably 15% or below. In this case, for the purpose of obtaining one having a wide latitude, it is also preferable that monodisperse emulsions as mentioned above are blended to be used in the same layer, or are applied in layers. As to the shape of the silver halide grains contained in the photographic emulsion, use can be made of grain in a regular crystal form, such as cubic, tetradecahedral, or octahedral, or grains in an irregular crystal form, such as spherical or planar, or grains that are a composite of these. Also, a mixture of silver halide grains having various crystal forms can be used. In the present invention, of these, grains containing grains in a regular crystal form in an amount of 50% or over, preferably 70% or over, and more preferably 90% or over, are preferred. Further, besides those mentioned above, an emulsion wherein the tabular grains having an average aspect ratio (the diameter of a circle calculated/the thickness) of 5 or over, and preferably 8 or over, exceed 50% of the total of the grains in terms of the projected area, can be preferably used. The silver chloromide emulsion used in the present invention can be prepared by methods described, for example, by P. Glafkides, in Chimie et Phisique Photographique (published by Paul Montel, 1967), by G.F. Duffin in Photographic Emulsion Chemistry (published by Focal Press, 1966), and by V.L. Zelikman et al. in Making and Coating Photographic Emulsion (published by Focal Press, 1964). That is, any of the acid process, the neutral process, the ammonia process, etc. can be used, and to react a soluble silver salt and a soluble halide, for example, any of the single-jet process, the double-jet process, or a combination of these can be used. A process of forming grains in an atmosphere having excess silver ions (the so-called reverse precipitation process) can also be used. A process wherein the pAg in the liquid phase where a silver halide is to be formed is kept constant, that is, the so-called controlled double-jet process, can be used as one type of double-jet process. According to the controlled double-jet process, a silver halide emulsion wherein the crystal form is regular and the grain sizes are nearly uniform can be obtained. Into the silver halide emulsion used in the present invention, various polyvalent metal ion impurities can be introduced during the formation or physical ripening of the emulsion grains. Examples of such compounds to be used include salts of cadmium, zinc, lead, copper, and thallium, and salts or complex salts of an element of Group VIII, such as iron, ruthenium, rhodium, palladium, osmium, iridium, and platinum. Particularly the elements of Group VIII can be preferably used. Although the amount of these compounds to be added varies over a wide range according to the purpose, preferably the amount is 10 -9 to 10 -2 mol for the silver halide. The silver halide emulsion used in the present invention is generally chemically sensitized and spectrally sensitized. As the chemical sensitization method, sulfur sensitization, wherein typically an unstable sulfur compound is added, noble metal sensitization, represented by gold sensitization, or reduction sensitization can be used alone or in combination. As the compounds used in the chemical sensitization, preferably those described in JP-A No. 215272/1987, page 18 (the right lower column) to page 22 (the right upper column), are used. The spectral sensitization is carried out for the purpose of providing the emulsions of the layers of the photographic material of the present invention with spectral sensitivities in desired wavelength regions. In the present invention, the spectral sensitization is preferably carried out by adding dyes that absorb light in the wavelength ranges corresponding to the desired spectral sensitivities, that is, by adding spectrally sensitizing dyes. As the spectrally sensitizing dyes used herein, for example, those described by F.M. Harmer in Heterocyclic compounds - Cyanine dyes and related compounds (published by John Wiley & Sons [New York, London], 1964) can be mentioned. As specific examples of the compounds and the spectral sensitization method, those described in the above JP-A No. 215272/1987, page 22 (the right upper column) to page 38, are preferably used. Preferably in the present invention a sparingly water-soluble epoxy compound represented by formula (I), (II), or (III) is incorporated in a silver halide photographic material that has at least one photosensitive layer containing silver halide emulsion grains which have been spectrally sensitized by a spectral sensitizing dye having a peak wavelength of spectral sensitivity at 730 nm. According to this embodiment a silver halide photographic material little in the change of sensitivity after storage thereof, suitable for infrared exposure and capable of being rapidly processed can be obtained. In the silver halide emulsion used in the present invention, various compounds or their precursors can be added for the purpose of stabilizing the photographic performance or preventing fogging that will take place during the process of the production of the photographic material, or during the storage or photographic processing of the photographic material. As specific examples of these compounds, those described in the above-mentioned JP-A No. 215272/1987, pages 39 to 72, are preferably used. As the emulsion used in the present invention, use is made of a so-called surface-latent image-type emulsion, wherein a latent image is formed mainly on the grain surface, or of a so-called internal latent image-type emulsion, wherein a latent image is formed mainly within the grains. The present invention is used for color photographic materials; generally in the color photographic material are used a yellow coupler, a magenta coupler, and a cyan coupler, which will couple with the oxidized product of the aromatic amine color-developing agent to form yellow, magenta, and cyan. Magenta couplers preferably used in the present invention are those represented by the following formulae (M-I) and (M-II): In formula (M-I), R 7 and R 9 each represent an aryl group, R 8 represents a hydrogen atom, an aliphatic or aromatic acyl group, an aliphatic or aromatic sulfonyl group, and Y 3 represents a hydrogen atom or a coupling split-off group. Allowable substituents of the aryl group represented by R 7 and R 9 are the same substituents as those allowable for the substituent R 1 , and if there are two substituents, they may be the same or different. R 8 is preferably a hydrogen atom, an aliphatic acyl group, or a sulfonyl group, and particularly preferably a hydrogen atom. Preferable Y 3 is of the type that will split-off at one of a sulfur atom, an oxygen atom, and a nitrogen atom, and particularly preferably of the sulfur atom split-off type described, for example, in U.S. Patent No. 4,351,897 and International Publication Patent No. WO 88/04795. In formula (M-II), R 10 represents a hydrogen atom or a substituent. Y 4 represents a hydrogen atom or a coupling split-off group, and particularly preferably a halogen atom or an arylthio group. Za, Zb, and Zc each represent methine, a substituted methine, =N-, or -NH-, and one of the Za-Zb bond and the Zb-Zc bond is a double bond, and the other is a single bond. If the Zb-Zc bond is a carbon-carbon double bond, it may be part of the aromatic ring. A dimer or more higher polymer formed through R 10 or Y 4 is included, and if Za, Zb, or Zc is a substituted methine, a dimer or more higher polymer formed through that substituted methine is included. Of the pyrazoloazole couplers represented by formula (M-II), imidazo[1,2-b]pyrazoles described in U.S. Patent No. 4,500,630 are preferable in view of reduced yellow subsidiary absorption of the color-formed dye and light-fastness, and pyrazolo[1,5-b][1,2,4] triazoles described in U.S. Patent No. 4,540,654 are particularly preferable. Further, use of pyrazolotriazole couplers wherein a branched alkyl group is bonded directly to the 2-, 3-, or 6-position of a pyrazolotriazole ring, as described in JP-A No. 65245/1976, pyrazoloazole couplers containing a sulfonamido group in the molecule, as described in JP-A No. 65246/1986, pyrazoloazole couplers having an alkoxyphenylsulfonamido ballasting group, as described in JP-A No. 147254/1986, and pyrazolotriazole couplers having an aryloxy group or an alkoxy group in the 6-position, as described in European Patent (Publication) Nos. 226,849 and 294,785, is preferable. Specific examples of couplers represented by formulae (M-I) and (M-II) are listed below. The couplers represented by formulae (M-I) and (M-II) are contained in the silver halide emulsion layer constituting the photographic layer generally in an amount of 0.1 to 1.0 mol, preferably 0.1 to 0.5 mol, per mol of the silver halide. In the present invention, in order to add the coupler to the photographic layer, various known techniques can be applied. Generally, the oil-in-water dispersion method known, as the oil-protect method, can be used for the addition, that is, after the coupler is dissolved in a solvent, it is emulsified and dispersed into an aqueous gelatin solution containing a surface-active agent. Alternatively, it is also possible that the coupler solution containing a surface-active agent can be added to water or an aqueous gelatin solution to form an oil-in-water dispersion with phase reversal of the emulsion. In the case of an alkali-soluble coupler, it can be dispersed by the so-called Fisher dispersion method. It is also possible that the low-boiling organic solvent can be removed from the coupler dispersion by means of distillation, noodle washing, ultrafiltration, or the like, followed by mixing with the photographic emulsion. As the dispersion medium for the couplers, it is preferable to use a high-boiling organic solvent and/or a water-insoluble polymer compound having a dielectric constant of 2 to 20 (25°C) and a refractive index of 1.5 to 1.7 (25°C). As high-boiling organic solvents, high-boiling organic solvents represented by the following formulae (A) to (E) are preferably used, wherein W 1 , W 2 , and W 3 each represent a substituted or unsubstituted, alkyl group, cycloalkyl group, alkenyl group, aryl group, or heterocyclic group, W 4 represents W 1 , O-W 1 or S-W 1 , n is an integer of 1 to 5, when n is 2 or over, W 4 groups may be the same or different, and in formula (E), W 1 and W 2 may together form a condensed ring. As the high-boiling organic solvent used in the present invention, any compound other than compounds represented by formulae (A) to (E) can also be used if the compound has a melting point of 100°C or below and a boiling point of 140°C or over, and if the compound is incompatible with water and is a good solvent for the coupler. Preferably the melting point of the high-boiling organic solvent is 80°C or below. Preferably the boiling point of the high-boiling organic solvent is 160°C or over, and more preferably 170°C or over. Details of these high-boiling organic solvents are described in JP-A No. 215272/1987, page 137 (the right lower column) to page 144 (the right upper column). The couplers can also be emulsified and dispersed into an aqueous hydrophilic colloid solution by impregnating them into a loadable latex polymer (e.g., U.S. Patent No. 4,203,716) in the presence or absence of the above-mentioned high-boiling organic solvent, or by dissolving them in a polymer insoluble in water and soluble in organic solvents. Preferably, homopolymers and copolymers described in International Publication Patent No. WO 88/00723, pages 12 to 30, are used, and particularly the use of acrylamide polymers is preferable because, for example, dye images are stabilized. The photographic material that is prepared by using the present invention may contain, as color antifoggant, for example, another hydroquinone derivative, an aminophenol derivative, a gallic acid derivative, or an ascorbic acid derivative. In the photographic material of the present invention, various anti-fading agent (discoloration preventing agent) can be used. That is, as organic anti-fading additives for cyan, magenta and/or yellow images, hydroquinones, 6-hydroxychromans, 6-hydroxycoumarans, spirochromans, p-alkoxyphenols, hindered phenols, including bisphenols, gallic acid derivatives, methylenedioxybenzenes, aminophenols, hindered amines, and ether or ester derivatives obtained by silylating or alkylating the phenolic hydroxyl group of these compounds can be mentioned typically. Metal complexes such as (bissalicylaldoximato)nickel complex and (bis-N,N-dialkyldithiocarbamato)nickel complexes can also be used. Specific examples of the organic anti-fading agents are described in the following patent specifications: Hydroquinones are described, for example, in U.S. Patent Nos. 2,360,290, 2,418,613, 2,700,453, 2,701,197, 2,728,659, 2,732,300, 2,735,765, 3,982,944, and 4,430,425, British Patent No. 1,363,921, and U.S. Patent Nos. 2,710,801 and 2,816,028; 6-hydroxychromans, 5-hydroxycoumarans, and spirochromans are described, for example, in U.S. Patent Nos. 3,432,300, 3,573,050, 3,574,627, 3,698,909, and 3,764,337 and JP-A No. 152225/1987; spiroindanes are described in U.S. Patent No. 4,360,589; p-alkoxyphenols are described, for example, in U.S. Patent No. 2,735,765, British Patent No. 2,066,975, JP-A No. 10539/1984, and JP-B No. 19765/1982; hindered phenols are described, for example, in U.S. Patent Nos. 3,700,455, JP-A No. 72224/1977, U.S. Patent No. 4,228,235, and JP-B No. 6623/1977; gallic acid derivatives, methylenedioxybenzenes, and aminophenols are described, for example, in U.S. Patent Nos. 3,457,079 and 4,332,886, and JP-B No. 21144/1981 respectively; hindered amines are described, for example, in U.S. Patent Nos. 3,336,135, 4,268,593, British Patent Nos. 1,326,889, 1,354,313, and 1,410,846, JP-B No. 1420/1976, and JP-A Nos. 114036/1983, 53846/1984, and 78344/1984; and metal complexes are described, for example, in U.S. Patent Nos. 4,050,938 and 4,241,155 and British Patent 2,027,731(A). To attain the purpose, these compounds can be added to the photosensitive layers by coemulsifying them with the corresponding couplers, with the amount of each compound being generally 5 to 100 wt% for the particular coupler. To prevent the cyan dye image from being deteriorated by heat, and in particular light, it is more effective to introduce an ultraviolet absorber into the cyan color-forming layer and the opposite layers adjacent to the cyan color-forming layers. As the ultraviolet absorber, aryl-substituted benzotriazole compounds (e.g., those described in U.S. Patent No. 3,533,794), 4-thiazolidone compounds (e.g., those described in U.S. Patent Nos. 3,314,794 and 3,352,681), benzophenone compounds (e.g., those described in JP-A No. 2784/1971), cinnamic acid ester compounds (e.g., those described in U.S. Patent Nos. 3,705,805 and 3,707,395), butadiene compounds (e.g., those described in U.S. Patent No. 4,045,229), or benzoxazole compounds (e.g., those described in U.S. Patent Nos. 3,406,070, 3,677,672, and 4,271,307) can be used. Ultraviolet-absorptive couplers (e.g., α-naphthol type cyan dye forming couplers) and ultraviolet-absorptive polymers can, for example, be used also. These ultraviolet-absorbers may be mordanted in a particular layer. In particular, the above-mentioned aryl-substituted benzotriazole compounds are preferable. In the present invention, together with the above couplers, in particular together with the pyrazoloazole coupler, the following compounds are preferably used. That is, it is preferred that a compound (F), which will chemically bond to the aromatic amide developing agent remaining after the color-developing process, to form a chemically inactive and substantially colorless compound, and/or a compound (G), which will chemically bond to the oxidized product of the aromatic amide color developing agent remaining after the color-developing process, to form a chemically inactive and substantially colorless compound, are used simultaneously or separately, for example, to prevent the occurrence of stain due to the formation of a color-developed dye by the reaction of the couplers with the color-developing agent remaining in the film during storage after the processing or with the oxidized product of the color-developing agent, and to prevent other side effects. Preferable as compound (F) are those that can react with p-anisidine a the second-order reaction-specific rate k 2 (in trioctyl phosphate at 80°C) in the range of 1.0 l/mol·sec to 1 x 10 -5 l/mol·sec. The second-order reaction- specific rate can be determined by the method described in JP-A No. 158545/1983. If k 2 is over this range, the compound itself becomes unstable, and in some cases the compound reacts with gelatin or water to decompose. On the other hand, if k 2 is below this range, the reaction with the remaining aromatic amine developing agent becomes slow, resulting, in some cases, in the failure to prevent the side effects of the remaining aromatic amine developing agent, which prevention is aimed at by the present invention. More preferable as compound (F) are those that can be represented by the following formula (FI) or (FII): Formula (FI) R 11 - (A 1 ) n - X 1 wherein R 11 and R 12 each represent an aliphatic group, an aromatic group, or a heterocyclic group, n is 1 or 0, A 1 represents a group that will react with an aromatic amine developing agent to form a chemical bond therewith, X 1 represents a group that will react with the aromatic amine developing agent and split off, B 1 represents a hydrogen atom, an aliphatic group, an aromatic group, a heterocyclic group, an acyl group, or a sulfonyl group, Y 1 represents a group that will facilitate the addition of the aromatic amine developing agent to the compound represented by formula (FII), and R 11 and X 1 , or Y 1 and R 12 or B 1 , may bond together to form a ring structure. Of the processes wherein compound (F) bonds chemically to the remaining aromatic amine developing agent, typical processes are a substitution reaction and an addition reaction. Specific examples of the compounds represented by formulae (FI), and (FII) are described, for example, in JP-A Nos. 158545/1988, 283338/1987, European Published Patent Nos. 298,321 and 277,589. On the other hand, more preferable examples of compound (G), which will chemically bond to the oxidized product of the aromatic amine developing agent remaining after color development processing, to form a chemically inactive and colorless compound, can be represented by the following formula (GI): Formula (GI) R 13 - Z wherein R 13 represents an aliphatic group, an aromatic group, or a heterocyclic group, Z represents a nucleophilic group or a group that will decompose in the photographic material to release a nucleophilic group. Preferably the compounds represented by formula (GI) are ones wherein n CH 3 I value (R.G. Pearson, et al., J. Am. Cem. Soc ., 90 , 319 (1968)) is 5 or over, or a group derived therefrom. Specific examples of compounds reprsented by formula (GI) are described, for example, in European Published Patent No. 255722, JP-A Nos. 143048/1987 and 229145/1987, Japanese Patent Application Nos. 136724/1988 and 214681/1987, and European Published Patent Nos. 298321 and 277589. Details of combinations of compound (G) and compound (F) are described in European Published Patent No. 277589. The photographic material prepared in accordance with the present invention may contain, in the hydrophilic colloid layer, water-soluble dyes as filter dyes or to prevent irradiation, and for other purpose. Such dyes include oxonol dyes, hemioxonol dyes, styryl dyes, merocyanine dyes, cyanine dyes, and azo dyes. Among them, oxonol dyes, hemioxonol dyes, and merocyanine dyes are useful. In the photographic material according to the present invention, for the purpose to improve the sharpness of image or the like, it is preferable to add a dye capable of decolorization by processing, as described in European Patent No. 0,337,490A2, pp. 27 - 76 (among them, oxonol-type dyes are preferable) into the hydrophilic colloid layer in such amount that the optical reflection density at 680 nm of said photographic material would be 0.70 or over, and/or to add titanium oxide particles that has been surface-treated by divalent to tetravalent alcohol (e.g., trimethylolethane) in a amount of 12 wt.% or more (more preferably, 14 wt.% or more) into the water-resistant resin layer of the base. As a binder or a protective colloid that can be used in the emulsion layers of photographic materials of the present invention, gelatin is advantageously used, but other hydrophilic colloids can be used alone or in combination with gelatin. In the present invention, gelatin may be lime-treated gelatin or acid-processed gelatin. Details of the manufacture of gelatin is described by Arther Veis in The Macromolecular Chemistry of Gelatin (published by Academic Press,1964). In the photographic material of the present invention, it is preferable to add a mold-proofing agent as described in, for example, JP-A No. 271247/1988, in order to prevent occurrence of molds and fungi that would propagate in the hydrophilic colloid layer and deteriorate images. As a base to be used in the present invention, a transparent film, such as cellulose nitrate film, and polyethylene terephthalate film or a reflection-type base that is generally used in photographic materials can be used. For the objects of the present invention, the use of a reflection-type base is more preferable. The "reflection base" to be used in the present invention is one that enhances reflectivity, thereby making sharper the dye image formed in the silver halide emulsion layer, and it includes one having a base coated with a hydrophobic resin containing a dispersed light-reflective substance, such as titanium oxide, zinc oxide, calcium carbonate, and calcium sulfate, and also a base made of a hydrophobic resin containing a dispersed light-reflective substance. For example, there can be mentioned baryta paper, polyethylene-coated paper, polypropylene-type synthetic paper, a transparent base having a reflective layer, or additionally using a reflective substance, such as glass plate, polyester films of polyethylene terephthalate, cellulose triacetate, or cellulose nitrate, polyamido film, polycarbonate film, polystyrene film, and vinyl chloride resins. As the other reflection base, a base having a metal surface of mirror reflection or secondary diffuse reflection may be used. A metal surface having a spectral reflectance in the visible wavelength region of 0.5 or more is preferable and the surface is preferably made to show diffuse reflection by roughening the surface or by using a metal powder. The surface mat be a metal plate, metal foil or metal thin layer obtained by rolling, vapor deposition or galvanizing of metal, such as, for example, aluminum, tin, silver, magnesium and alloy thereof. Of these, a base obtained by vapor deposition of metal is preferable. It is preferable to provide a layer of water resistant resin, in particular, a layer of thermoplastic resin. The opposite side to metal surface side of the base according to the present invention is preferably provided with an antistatic layer. The details of such base described, for example, in JP-A Nos. 210346/1986, 24247/1988, 24251/1988, and 24255/1988. Further, as a base for use in the photographic material of the present invention, a white polyester film base or a base that is provided a layer containing a white pigment on the base of the silver halide emulsion layer side may be used for display purpose. Further, it is preferable to apply an antihalation layer on the silver halide emulsion layer side or on back side. In particular, it is preferable to set the transmission density of base in a range of 0.35 to 0.8 so as to be able to view a display both under reflected light and transmitted light. These bases can be suitably selected according to the purpose for use. It is advantageous that, as the light-reflective substance, a white pigment is kneaded well in the presence of a surface-active agent, and it is preferable that the surface of the pigment particles has been treated with a divalent to tetravalent alcohol. The occupied area ratio (%) per unit area prescribed for the white pigments finely divided particles can be obtained most typically by dividing the observed area into contiguous unit areas of 6 µm x 6 µm, and measuring the occupied area ratio (%) (Ri) of the finely divided particles projected onto the unit areas. The deviation coefficient of the occupied area ratio (%) can be obtained based on the ratio s/ R , wherein s stands for the standard deviation of Ri, and R stands for the average value of Ri. Preferably, the number (n) of the unit areas to be subjected is 6 or more. Therefore, the deviation coefficient s/ R can be obtained by In the present invention, preferably the deviation coefficient of the occupied area ratio (%) of the finely divided particles of a pigment is 0.15 or below, and particularly 0.12 or below. If the variation coefficient is 0.08 or below, it can be considered that the substantial dispersibility of the particles is substantially "uniform". Preferably, the color developer used for the development processing of the photographic material of the present invention is an aqueous alkaline solution whose major component is an aromatic primary amine color-developing agent. As the color-developing agent, aminophenol compounds are useful, though p-phenylene diamine compounds are preferably used, and typical examples thereof include 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, and 3-methyl-4-amino-N-ethyl-N-β-methoxyethylaniline, and their sulfates, hydrochlorides, and p-toluenesulfonates. A combination of two or more of these compounds may be used in accordance with the purpose. The color developer generally contains, for example, buffers, such as carbonates or phosphates of alkali metals, and development inhibitors or antifoggants, such as bromide salts, iodide salts, benzimidazoles, benzothiazoles, or mercapto compounds. The color developer may, if necessary, contain various preservatives, such as hydroxylamine, diethylhydroxylamine, sulfites, hydrazines for example N,N-biscarboxymethylhydrazine, phenylsemicarbazides, triethanolamine, and catecholsulfonic acids, organic solvents such as ethylene glycol and diethylene glycol, development accelerators such as benzyl alcohol, polyethylene glycol, quaternary ammonium salts, and amines, dye forming couplers, competing couplers, auxiliary developers such as 1-phenyl-3-pyrazolidone, tackifiers, and various chelate agents as represented by aminopolycarboxylic acids, aminopolyphosphonic acids, alkylphosphonic acids, and phosphonocarboxylic acids, typical example thereof being ethylenediaminetetraacetic acid, nitrilotriacetic acid, diethylenetriaminepentaacetic acid, cyclohexanediaminetetraacetic acid, hydroxyethyliminodiacetic acid, 1-hydroxyethylidene-1,1-diphosphonic acid, nitrilo-N,N,N-trimethylenephosphonic acid, ethylenediamine-N,N,N',N'-tetramethylenephosphonic acid, and ethylenediamine-di(o-hydroxyphenylacetic acid), and their salts. If reversal processing is carried out, it is common that after black and white development and reversal processing are carried out, the color development is carried out. As the black and white developers, known black and white developing agents, such as dihydroxybenzenes, for example hydroquinone, 3-pyrazolidones, for example 1-phenyl-3-pyrazolidone, and aminophenols, for example N-methyl-p-aminophenol, can be used alone or in combination. Generally the pH of this color developer and black-and-white developing solution is 9 to 12. The replenishing amount of these developing solutions is generally 3 liter or below per square meter of the color photographic material to be processed, though the replenishing amount changes depending on the type of color photographic material, and if the concentration of bromide ions in the replenishing solution is lowered previously, the replenishing amount can be lowered to 500 ml or below per square meter of the color photographic material. If it is intended to lower the replenishing amount, it is preferable to prevent the evaporation of the solution and oxidation of the solution with air by reducing the area of the solution in processing tank that is in contact with the air. The contact area of the photographic processing solution with the air in the processing tank is represented by the opened surface ratio which is definited as follows: Opened surface ratio (cm -1 ) = Contact surface area (cm 2 ) of the processing solution with the air Whole volume (cm 3 ) of the processing solution wherein "contact surface area of the processing solution with the air" means a surface area of the processing solution that is not covered by anything such as floating lids or rolls. The opened surface ratio is preferably 0.1 cm -1 or less, more preferably 0.001 to 0.05 cm -1 . Methods for reducing the opened surface ratio that can be mentioned include a utilization of movable lids as described in JP-A NO. 241342/1987 and a slit-developing process as described in JP-A No. 216050/1988, besides a method of providing a shutting materials such as floating lids. It is preferable to adopt the means for reducing the opened surface ratio not only in a color developing and black-and-white developing process but also in all succeeding processes, such as bleaching, bleach-fixing, fixing, washing, and stabilizing process. It is also possible to reduce the replenishing amount by using means of suppressing the accumulation of bromide ions in the developer. Although the processing time of color developing is settled, in generally, between 2 and 5 minutes, the time can be shortened by, for example, processing at high temperature and at high pH, and using a color developer having high concentration of color developing agent. The photographic emulsion layer are generally subjected to a bleaching process after color development. The beaching process can be carried out together with the fixing process (bleach-fixing process), or it can be carried out separately from the fixing process. Further, to quicken the process bleach-fixing may be carried out after the bleaching process. In accordance with the purpose, the process may be arbitrarily carried out using a bleach-fixing bath having two successive tanks, or a fixing process may be carried out before the bleach-fixing process, or a bleaching process. As the bleaching agent, use can be made of, for example, compounds of polyvalent metals, such as iron (III). As typical bleaching agent, use can be made of organic complex salts of iron (III), such as complex salts of aminopolycarboxylic acids, for example ethylenediaminetetraacetic acid, diethylenetriaminetetraacetic acid, cyclohexanediaminetetraacetic acid, methyliminodiacetic acid, 1,3-diaminopropanetetraacetic acid, and glycoletherdiaminetetraacetic acid, citric acid, tartaric acid, and malic acid. Of these, aminopolycarboxylic acid iron (III) complex salts, including ethylenediaminetetraacetic acid iron (III) complex salts are preferable in view of rapid-processing and the prevention of pollution problem. Further, aminopolycarboxylic acid iron (III) complex salts are particularly useful in a bleaching solution as well as a bleach-fixing solution. The pH of the bleaching solution or the bleach-fixing solution using these aminopolycarboxylic acid iron (III) complex salts is generally 4.0 to 8.0, by if it is required to quicken the process, the process can be effected at a low pH. In the bleaching solution, the bleach-fixing solution, and the bath preceding them a bleach-accelerating agent may be used if necessary. Examples of useful bleach-accelerating agents are compounds having a mercapto group or a disulfide linkage, described in U.S. Patent No. 3,893,858 West German Patent No. 1,290,812, JP-A No. 95630/1978, and Research Disclosure No. 17129 (July, 1978); thiazolidine derivatives, described in JP-A No. 140129/1975; thiourea derivatives, described in U.A. Patent No. 3,706,561; iodide salts, described in JP-A No. 16235/1983; polyoxyethylene compounds in West German Patent No. 2,748,430; polyamine compounds, described in JP-B No. 8836/1970; and bromide ions. Of these, compounds having a mercapto group or a disulfide group are preferable in view of higher acceleration effect, and in particular, compounds described in U.A. Patent No. 3,893,858, West German Patent No. 1,290,812, and JP-A No. 95630/1978 are preferable. Compound described in U.S. Patent No. 4,552,834 are preferable. These bleach-accelerating agents may be added into a photographic material. When the color photographic materials for photographing are to be bleach-fixed, these bleach-accelerating agents are particularly effective. As a fixing agent can be mentioned thiosulfates, thiocyanates, thioether-type compounds, thioureas, and large amounts of iodide salts, although thiosulfate is used usually, and in particular ammonium thiosulfate is widely used. As the preservative for bleach-fix solution sulfite salt, bisulfite salt, or carbonyl-bisulfite adduct is preferably. It is common for the silver halide color photographic material of the present invention to undergo, after a desilvering process such as fixing or bleach-fix, a washing step and/or a stabilizing step. The amount of washing water may be set within a wide range depending on the characteristics (e.g., due to the materials used, such as couplers), the application of the photographic material, the washing temperature, the number of washing tanks (the number if steps), the type of replenishing system, including, for example, the counter-current system and the direct flow system and other various conditions. Of these, the relationship between the number of water-washing tanks and the amount of washing water in the multi-stage counter current system can be found according to the method described in Journal of Society of Motion Picture and Television Engineers, Vol. 64, pages 248 to 253 (May 1955). According to the multi-stage-counter-current system described in the literature mentioned above, although the amount of washing water can be considerably reduced, bacteria propagate with an increase of retention time of the washing water in the tanks, leading to a problem with the resulting suspend matter adhering to the photographic material. In processing the present color photographic material, as a measure to solve this problem the method of reducing calcium and magnesium described in JP-A No. 288838/1987 can be used quite effectively. Also chlorine-type bactericides such as sodium chlorinated isocyanurate, cyabendazoles, isothiazolone compounds described in JP-A No. 8542/1982, benzotriazoles, and other bactericides described by Hiroshi Horiguchi in Bokin Bobai-zai no Kagaku, (1986) published by Sankyo-Shuppan, Biseibutsu no Mekkin, Sakkin, Bobaigijutsu (1982) edited by Eiseigijutsu-kai, published by Kogyo-Gijutsu-kai, and in Bokin Bobaizai Jiten (1986) edited by Nihon Bokin Bobai-gakkai), can be used. The pH of the washing water used in processing the present photographic material is 4 to 9, preferably 5 to 8. The washing water temperature and the washing time to be set may very depending, for example, on the characteristics and the application of the photographic material, and they are generally selected in the range of 15 to 45°C for 20 sec to 10 min, and preferably in the range of 25 to 40°C for 30 sec to 5 min. Further, the photographic material of the present invention can be processed directly with a stabilizing solution instead of the above washing. In such a stabilizing process, any of known processes, for example, a multi-step counter-current stabilizing process or its low-replenishing-amount process, described in JP-A Nos. 8543/1982, 14834/1983, and 220345/1985. In some cases, the above washing process is further followed by stabilizing process, and as an example thereof can be mentioned a stabilizing bath that is used as a final bath for color photographic materials for photography, which contains formalin and a surface-active agent. In this stabilizing bath, each kind of the chelating agents and bactericides may be added. The over-flowed solution due to the replenishing of washing solution and/or stabilizing solution may be reused in other steps, such as a desilvering step. The silver halide color photographic material of the present invention may contain therein a color-developing agent for the purpose of simplifying and quickening the process. To contain such a color-developing agent, it is preferable to use a precursor for color-developing agent. For example, indoaniline-type compounds described in U.S. Patent No. 3,342,597, Schiff base-type compounds described in U.S. Patent No. 3,342,599 and Research Disclosure Nos. 14850 and 15159, aldol compounds described in Research Disclosure No. 13924, and metal salt complexes described in U.S. Patent No. 3,719,492, and urethane-type compounds described in JP-A No. 135628/1978 can be mentioned. For the purpose of accelerating the color development, the present silver halide color photographic material may contain, if necessary, various 1-phenyl-3-pyrazolicones. Typical compounds are described in JP-A Nos. 64339/1981, 144547/1982, and 115438/1983. The various processing solutions used for the present invention may be used at 10 to 50°C. Although generally a temperature of 33 to 38°C may be standard, a higher temperature can be used to accelerate the process to reduce the processing time, or a lower temperature can be used to improve the image quality or the stability of the processing solution. Also, to save the silver of the photographic material, a process using hydrogen peroxide intensification or cobalt intensification described in West German Patent No. 2,226,770 and U.S. Patent No. 3,674,499 may be carried out. The silver halide color photographic material of the present invention forms a dye image excellent in preservability of color image that is restrained light-fading, dark-fading, fading in high humidity and fading due to acid. Next, the present invention will be described in detail in accordance with examples, but the invention is not limited to these ezamples. Example 1 A multilayer color photographic paper A (for comparison) was prepared by multi-coatings composed of the following layer composition on a two-side polyethylene laminated paper support. Coating solutions were prepared as follows: Preparation of the first layer coating solution To a mixture of 19.1 g of yellow coupler (ExY), 4.4 g of image-dye stabilizer (Cpd-1) and 0.7 g of image-dye stabilizer (Cpd-7), 27.2 ml of ethyl acetate and 8.2 g of solvent (Solv-1) were added and dissolved. The resulting solution was dispersed and emulsified in 185 ml of 10% aqueous gelatin solution containing 8 ml of sodium dodecylbenzenesulfonate. Separately another emulsion was prepared by adding two kinds of blue-sensitive sensitizing dye, shown below, to a blend of silver chlorobromide emulsions (cubic grains, 3 : 7 (silver mol ratio) blend of grains having 0.88 µm and 0.70 µm of average grain size, and 0.08 and 0.10 of deviation coefficient of grain size distribution, respectively, each in which 0.2 mol% of silver bromide was located at the surface of grains) in such amounts that each dye corresponds 2.0 x 10 -4 mol to the large size emulsion and 2.5 x 10 -4 mol to the small size emulsion, per mol of silver, and then sulfur-sensitized. The thus-prepared emulsion and the above-obtained emulsified dispersion were mixed together and dissolved to give the composition shown below, thereby preparing the first layer coating solution. Coating solutions for the second to seventh layers were also prepared in the same manner as the first layer coating solution.
