Description: FIELD OF THE INVENTION This invention relates to a silver halide color reversal photographic material having improved image quality. More particularly, it relates to a silver halide color reversal photographic material having improved tone reproducibility and improved color reproducibility. BACKGROUND OF THE INVENTION In recent years, there has been an increasing demand for color photographic materials having high image quality. Satisfying the demand requires multifaceted and synthetic improvements of photographic characteristics embracing image structures such as sharpness and graininess, color reproducibility, tone reproducibility, and the like. With respect to color reproducibility, there is a need not only to reproduce a hue with good fidelity but to reproduce a bright tone and more accurate. In order to achieve brighter color reproduction, so-called masking or an interimage effect has been utilized as disclosed in U.S. Patent 2,521,908. Details of an interimage effect are described, e.g., Hanson, et al., Journal of the Optical Society of America , Vol. 42, pp. 663-669 and A. Thiels, Zeitshrift für Wissenschaftliche Photographie, Photophysique und Photochemie , Vol. 47, pp. 106-118 and 246-255. U.S. Patent 3,536,486 discloses a method for obtaining an interimage effect by introducing diffusible 4-thiazolin-2-thione into an exposed color reversal element, and U.S. Patent 3,536,487 discloses a method for obtaining an interimage effect by introducing diffusible 4-thiazolin-2-thion into an unexposed color reversal photographic element. JP-B-48-34169 (the term "JP-B" as used herein means an "examined published Japanese patent application") describes that a marked interimage effect can be obtained by reducing silver halide to silver by development in the presence of an N-substituted-4-thiazolin-2-thion compound. Research Disclosure No. 13116 (March, 1975) describes that a colloidal silver-containing layer is provided between a cyan layer and a magenta layer of a color reversal photographic element to obtain an interimage effect. U.S. Patent 4,082,553 discloses a method for obtaining an interimage effect in a color reversal photographic material having such a layer structure which permits migration of iodide ions during development wherein latent image-forming silver haloiodide grains are incorporated into one of the constituting layers, and latent image-forming silver halide grains and silver halide grains whose surface have been fogged so as to be developable irrespective of imagewise exposure are incorporated into another constituting layer. In addition, JP-A-62-11854 (the term "JP-A" as used herein means an "unexamined published Japanese patent application") discloses an improvement in interimage effect of a color reversal photographic material which is brought about by addition of a 5-mercapto-1,3,4-thiadiazole compound. EP-A-0423742, which belongs to the prior art under Art. 54(3) EPC, discloses a silver halide color reversal photographic photosensitive material containing a microcrystalline dispersion of specific compounds and aiming at improving sharpness, color reproduction and de-silvering properties. U.S. Patent 4,788,132 discloses a silver halide photographic material containing specific thiadiazol compounds in order to increase interimage effects and improve sharpness and granularity. Thus, color reproducibility and, in particular, saturation can be improved by enhancing an interimage effect. However, production of an interimage effect in excess results in insufficient reproduction of a delicate shade of color possessed by an original and reproduction of shade. Such a loss of gradation is considered to be due to absence or flattening of gradation of a complementary color in the image area where an original color should be reproduced, and this is a great evil of an interimage effect. For example, when a red color is photographed, gradation of a cyan color is lost or flattened by a great interimage effect so that a bright red color is reproduced but, in turn, a delicate shade in the shade portion cannot be reproduced (so-called gradation loss of red). When a yellow color is photographed, cyan and magenta densities become low and flattened, making reproduction of bright yellow possible, but failing to reproduce a tone of the shade (gradation loss of yellow). On the other hand, in the area where a bright red color should be reproduced, if a complementary color, i.e., cyan, becomes too hard, reproduction of a shade can be improved, but saturation is unfavorably reduced. Thus, the exposure range where a complementary color is incorporated and the amount of the incorporated complementary color impact significantly on saturation and description of shades. The above-described exposure range where a complementary color is incorporated and the amount of the incorporated complementary color can be adjusted to some extent by controlling interimage effect, spectral sensitivity distribution, and the like. However, conventional techniques which have been proposed to date have found great difficulty in achieving strict control of these factors. Moreover, whether a given exposure range where a complementary color is incorporated and the amount thereof would be the most suitable for desired saturation and description of shades has not yet been determined. SUMMARY OF THE INVENTION An object of the present invention is to provide a silver halide color reversal photographic material which has high chroma and saturation in low to middle density areas without impairing color reproducibility and which is excellent in reproducibility of delicate shades in a high density area. The above and other objects and advantages of the present invention are accomplished by a silver halide color reversal photographic material comprising a support having thereon at least one cyan coupler-containing red-sensitive silver halide emulsion layer, at least one magenta coupler-containing green-sensitive silver halide emulsion layer, and at least one yellow coupler-containing blue-sensitive silver halide emulsion layer, wherein the total light-sensitive silver halide grains in the photographic material have an average silver iodide content of about 5.5 mol% or less, and at least one of said light-sensitive silver halide emulsion layers and/or at least one substantially light-insensitive hydrophilic colloidal layer adjacent thereto comprises means for producing an interimage effect, said interimage effect satisfying at least one of relationships (a) and (b): (a) 0.20 ≤ ΔlogE(R 0.5 ) ≤ 0.40, 0 ≤ ΔlogE(R 1.5 ) ≤ 0.07, and 0.18 ≤ ΔlogE(R 0.5 ) - ΔlogE(R 1.5 ) ≤ 0.35 (b) 0.25 ≤ ΔlogE(G 0.5 ) ≤ 0.45, 0 ≤ ΔlogE(G 1.5 ) ≤ 0.15, and 0.23 ≤ ΔlogE(G 0.5 ) - ΔlogE(G 1.5 ) ≤ 0.35 wherein ΔlogE(R 0.5 ) and ΔlogE(R 1.5 ) each represent an interimage effect on a red-sensitive silver halide emulsion layer at a cyan density of 0.5 and 1.5, respectively; and ΔlogE(G 0.5 ) and ΔlogE(G 1.5 ) each represent an interimage effect on a green-sensitive silver halide emulsion layer at a magenta density of 0.5 and 1.5, respectively. BRIEF DESCRIPTION OF THE DRAWING Figure 1 shows an HD curve of the light-sensitive material of the present invention exposed to white light or red light and developed. Figure 2 shows spectral transmittance of filters used in the present invention. DETAILED DESCRIPTION OF THE INVENTION "Means for producing an interimage effect" which can be used in the present invention are described below with respect to vaious embodiments which can be employed to achieve the above-mentioned relationships (a) and (b). These include the followings. (1) At least one pair of light-sensitive silver halide emulsion layers differing in color sensitivity have a difference of at least 1 mol% in average silver iodide content. (2) The light-sensitive material contains a compound capable of releasing a development inhibitor or a precursor thereof on oxidation-reduction reaction with an oxidation product of a developing agent. (3) The light-sensitive material contains a compound represented by formula (III) hereinafter described. (4) The light-sensitive material contains at least one of a diffusible 4-thiazolin-2-thion compound and an N-substituted-4-thiazolin-2-thion compound. (5) The light-sensitive material contains a silver halide emulsion comprising surface-fogged silver halide grains. (6) The light-sensitive material contains a silver halide emulsion comprising internally-fogged silver halide grains. (7) The light-sensitive material contains colloidal silver in a layer other than a yellow filter layer or an antihalation layer. (8) The light-sensitive material contains an electron donor-releasing coupler. In a preferred embodiment of the present invention, an interimage effect can be efficiently exercised by satisfying the condition specified in means (1), and incorporating at least one of the substances specified in means (2) to (8), and preferably at least one of the substances of means (2), (3), (5) and (6), into at least one of the light-sensitive silver halide emulsion layers and substantially light-insensitive hydrophilic colloidal layers. It is preferable that both the emulsion layer and the light-insensitive hydrophilic colloidal layer be provided with means for producing an interimage effect. In this case, means other than (1) are preferably provided to the above-described emulsion layers and the light-insensitive layers adjacent thereto, and more preferably provided to the light insensitive layer adjacent to the low-speed silver halide emulsion layer among layers having the same color sensitivity. The effects of the present invention can also be obtained where the interimage effect-producing means are provided only to the light-insensitive layers. In order to satisfy the relationship (a), means (2) to (8) is preferably applied to the red-sensitive layer and/or a light-insensitive hydrophilic colloid layer adjacent thereto. On the other hand, in order to satisfy the relationship (b), means (2) to (8) is preferably applied to the green-sensitive layer and/or a light-insensitive hydrophilic layer adjacent thereto. The degree of an interimage effect can be controlled in a strict manner by using the above-described means in the manner described. The interimage effect thus produced can be determined according to the following method. (i) Cyan, magenta and yellow densities on exposure to white light (red light + green light + blue light): A sample is exposed through a continuous wedge to light through a filter "Fuji Filter SC-64" (produced by Fuji Photo Film Co., Ltd.) for 1/10 of a second using a tungsten light source to which a color conversion filter of 4800°K is fitted (red light exposure). Then, the same sample is exposed to light in the same manner, except for using a filter "BPN-55" (produced by Fuji Photo Film Co., Ltd.) in place of "SC-64" (green light exposure). Finally, the same sample is exposed to light in the same manner, except for using "BPN-45" (produced by Fuji Photo Film Co., Ltd.) as a filter (blue light exposure). Spectral transmittance of these filters are shown in Figure 2. Exposure to white light is thus achieved by exposing a sample three times each using a filter, SC-64, BPN-55, or BPN-45. The exposed sample is subjected to color reversal development in a prescribed manner, and cyan, magenta and yellow densities are measured. When the color balance of the developed sample is not gray, the exposure amounts in the above-described red light exposure, green light exposure and blue light exposure are adjusted so that the color balance of the developed sample becomes gray. The measured densities of cyan, magenta and yellow are converted to analytical spectral densities by the method described in James, The Theory of the Photographic Process , p. 525 to prepare HD curves of cyan, magenta and yellow. (ii) Cyan density on exposure to red light: A sample is exposed to red light under the same conditions as used for red light exposure in the white light exposure above and subjected to color reversal development in the prescribed manner. The cyan, magenta, and yellow densities are measured, and the measured densities are converted to analytical spectral densities in the same manner as in (i) above to prepare an HD curve for cyan. (iii) Magenta density on green light exposure: A sample is exposed to green light under the same conditions as used for green light exposure in the white light exposure above and subjected to color reversal development in the prescribed manner. The cyan, magenta, and yellow densities are measured, and the measured densities are converted to analytical spectral densities in the same manner as in (i) above to prepare an HD curve for magenta. (iv) Determination of ΔlogE(R 0.5 ) and ΔlogE(R 1.5 ): The difference between the cyan HD curves prepared in (i) and (ii) above in exposure amount at a cyan density of 0.5 or 1.5 was taken as ΔlogE(R0.5) or ΔlogE(R1.5), respectively (see Fig. 1). (v) Determination of ΔlogE(G 0.5 ) and ΔlogE(G 1.5 ): The difference between the magenta HD curves prepared in (i) and (ii) above in exposure amount at a magenta density of 0.5 or 1.5 was taken as ΔlogE(G 0.5 ) or ΔlogE(G 1.5 ), respectively. The interimage effect according to the present invention satisfies at least one of relationships (a) and (b): (a) 0.20 ≤ ΔlogE(R 0.5 ) ≤ 0.40, 0 ≤ ΔlogE(R 1.5 ) ≤ 0.07, and 0.18 ≤ ΔlogE(R 0.5 ) - ΔlogE(R 1.5 ) ≤ 0.35 (b) 0.25 ≤ ΔlogE(G 0.5 ) ≤ 0.45, 0 ≤ ΔlogE(G 1.5 ) ≤ 0.15, and 0.23 ≤ ΔlogE(G 0.5 ) - ΔlogE(G 1.5 ) ≤ 0.35 It is preferable that an interimage effect exercised on a red-sensitive emulsion layer satisfies relationship (a) and that an interimage effect exercised on a green-sensitive emulsion layer satisfies relationship (b). The interimage effect on a red-sensitive emulsion layer more preferably satisfies the following relationship (a'): (a') 0.20 ≤ ΔlogE(R 0,5 ) ≤ 0.38, 0.01 ≤ ΔlogE(R 1.5 ) ≤ 0.07, and 0.19 ≤ ΔlogE(R 0.5 ) - ΔlogE(R 1.5 ) ≤ 0.34 The interimage effect on a green-sensitive emulsion layer more preferably satisfies the following relationship (b'): (b') 0.26 ≤ ΔlogE(G 0.5 ) ≤ 0.44, 0.01 ≤ ΔlogE(G 1.5 ) ≤ 0.15, and 0.24 ≤ ΔlogE(G 0.5 ) - ΔlogE(G 1.5 ) ≤ 0.34 The total light-sensitive silver halide grains in the light-sensitive material according to the present invention have an average silver iodide content of about 5.5 mol% or less, preferably 5.2 mol% or less, and more preferably between 5.0 mol% and 1.7 mol%. The reason for the comparative low average silver iodide content is that if the content is large the interimage effect produced does not fall within the above-specified relationships even where interimage effect-producing means (1) and at least one of (2) to (8) are provided. In means (2), the at least one pair of light-sensitive silver halide emulsion layers may be any combination selected from three color sensitive emulsion layers. The difference of the average silver iodide is preferably at most 6 mol%, and preferably from 1 to 5 mol%. The redox compound capable of releasing a development inhibitor or a precursor thereof on oxidation-reduction reaction with an oxidation product of a developing agent as described in means (2) is explained below. The compound is preferably those which are represented by formula (II) or (IV): A - (Time) t - X wherein A represents an oxidation-reduction nucleus, i.e., an atomic group which allows (Time) t X to be released therefrom upon being oxidized during development processing; Time represents a timing group linked to A through a sulfur atom, a nitrogen atom or an oxygen atom; t represents 0 or 1; and X represents a development inhibitor moiety; wherein R 1 represents an aliphatic or aromatic group; G 1 represents or an iminomethylene group; R 2 represents an alkoxy group, an aryloxy group, or an amino group; A 1 and A 2 both represent a hydrogen atom, or one of them represents a hydrogen atom with the other representing a substituted or unsubstituted alkylsulfonyl sulfonyl group, a substituted or unsubstituted group, or a substituted or unsubstituted acyl group; Time represents a divalent linking group; t represents 0 or 1; and PUG represents a development inhibitor moiety.

The amino group in A is preferably substituted with a sulfonyl group having from 1 to 25 carbon atoms or an acyl group having from 1 to 25 carbon atoms. The sulfonyl group includes substituted or unsubstituted aliphatic or aromatic sulfonyl groups, and the acyl group includes substituted or unsubstituted aliphatic or aromatic acyl groups (the same for definitions of formula (II)). The hydroxyl group or amino group in A may be protected with a protecting group which is removable on development processing. Examples of such a protecting group include those having from 1 to 25 carbon atoms, e.g., an acyl group, an alkoxycarbonyl group, a carbamoyl group, and protecting groups described in JP-A-59-197037 and JP-A-59-201057 (corresponding to U.S. Patents 4,629,683 and 4,518,685, respectively). The protecting group, if possible, may be connected to a substituent of A hereinafter described to form a 5-, 6- or 7-membered ring. The oxidation-reduction nucleus as represented by A may have appropriate substituents as long as the redox ability thereof is not impaired. Such substituents include those having from 2 to 5 carbon atoms, e.g., an alkyl group, an aryl group, an alkylthio group, an arylthio group, an alkoxy group, an aryloxy group, an amino group, an amido group, a sulfonamido group, an alkoxycarbonylamino group, a ureido group, a carbamoyl group, an alkoxycarbonyl group, a sulfamoyl group, a sulfonyl group, a cyano group, a halogen atom, an acyl group, and a carboxyl group. (Time) t X in formula (II) is a group which is released from A as ⊖ (Time) t X when the nucleus A undergoes cross-oxidation reaction during development and becomes an oxidized form. "Time" is a timing group linked to A through a sulfur atom, a nitrogen atom, or an oxygen atom and includes those releasing X from the released ⊖ (Time) t X through one or more reaction steps. Examples of such a timing group are described, e.g., in U.S. Patents 4,248,962 and 4,409,323, British Patent 2,096,783, U.S. Patent 4,146,396, JP-B-51-146828, and JP-B-57-56837. "Time" may be a combination of two or more groups selected from those disclosed. X in formula (II) represents a development inhibitor moiety. Suitable development inhibitors include heterocyclic compounds having a mercapto group bonded to the hetero ring thereof and heterocyclic groups capable of forming imino-silver.

The diffusible 4-thiazolin-2-thione compound and N-substituted-4-thiazolin-2-thion compound which can be used in means (4) are described in U.S. Patent 3,536,487 and JP-B-48-34169, respectively. An example of compound is The amount of the compound used in means (4) to be added preferably ranges from about 1 × 10 -6 to about 1 mol, and more preferably from 1 × 10 -4 to 1 × 10 -1 mol, per mol of light-sensitive silver halide. It is preferred that the compound is added to a light-sensitive emulsion layer. The silver halide emulsion comprising surface-fogged silver halide grains which can be used in means (5) and the silver halide emulsion comprising internally-fogged silver halide grains which can be used in means (6) are described in U.S. Patent 4,082,553 and U.S. Patent 4,626,498, respectively. The terminology "internally-fogged or surface-fogged silver halide emulsion" as used herein means a silver halide emulsion which is evenly (non-imagewise) developed, exposed or unexposed, without distinction. The internally-fogged silver halide emulsion is an emulsion comprising core/shell type silver halide grains comprising an internal nucleus having its surface fogged and an outer shell covering the surface of the internal nucleus. Relatively little development occurs in the initial stage of development. However, 30% or more of the total silver thereof is developed in color reversal development involving a sensitizing treatment and a desensitizing treatment irrespective of whether the emulsion is exposed to light or not. The surface-fogged silver halide emulsion can be prepared by adding a reducing agent or a gold salt to an emulsion capable of forming a surface latent image under appropriate pH and pAg conditions, heating an emulsion capable of forming a surface latent image under a low pAg condition, or uniformly exposing an emulsion capable of forming a surface latent image to light. Examples of suitable reducing agents are stannous chloride, hydrazine compounds, and ethanolamine. The surface-fogged silver halide emulsion may also have the inside of the grains fogged. The internally-fogged silver halide emulsion can be prepared by depositing silver halide on the surface of the above-described surface-fogged silver halide grains to form an outer shell. The dissolving physical development can be controlled in accordance with the timing of the development by varying the thickness of the outer shell of the internally-fogged core/shell type silver halide grains. The suitable thickness of the outer shell varies depending on the development processing, development time, timing of development of each light-sensitive silver halide emulsion layer, and the like. Satisfactory results can be obtained usually by setting the thickness between about 3 and about 100 nm (30-1,000 Å), preferably between 5 and 50 nm (50-500 Å). In the internally-fogged core/shell type silver halide grains, the core and the outer shell may have either the same or different halogen composition. The internally-fogged or surface-fogged silver halide grains may have any halogen composition selected from, e.g., silver chloride, silver chlorobromide, silver iodobromide, or silver chloroiodobromide. While these fogged silver halide grains are not particularly limited in grain size, a preferred mean grain size is from about 0.01 to about 0.75 µm, and more preferably from 0.05 to 0.6 µm. The fogged silver halide grains are not particularly limited in crystal form, either regular or irregular. A poly-dispersed emulsion can be used, but a mono-dispersed emulsion (in which at least 95% of the weight or number of silver halide grains have a grain size falling within ±40% of a mean grain size) is preferred. The internally-fogged or surface-fogged silver halide emulsion is incorporated into at least one silver halide light-sensitive layer farthest from the support or at least one other layer between the farthest layer and the support, and is preferably incorporated into a silver halide light-sensitive layer and/or a substantially light-insensitive hydrophilic colloidal layer adjacent thereto. Where there are two or more light-sensitive layers having the same color sensitivity but different light-sensitivity, the internally-fogged or surface-fogged silver halide emulsion is preferably incorporated into a layer other than the layer having the highest sensitivity and/or a substantially light-insensitive hydrophilic colloidal layer adjacent thereto. The amount of the internally-fogged or surface-fogged silver halide to be added preferably ranges from about 0.05 to about 50 mol%, and more preferably from 0.1 to 40 mol%, based on the light-sensitive silver halide present in the layer to which it is added or in at least one light-sensitive silver halide layer adjacent to the layer to which it is added, but may vary depending on the development conditions, timing of development of each layer, and the like. Addition of colloidal silver as described in means (7) is described in Research Disclosure , No. 131, p. 13116. In means (7), colloidal silver is incorporated into at least one of silver halide emulsion layers and light-insensitive layers (other than a yellow filter layer and an antihalation layer) adjacent thereto, and preferably into a low sensitivity green-sensitive silver halide emulsion layer, a low sensitivity red-sensitive silver halide emulsion layer, and a substantially light-insensitive hydrophilic colloidal layer adjacent to these light-sensitive layers. The preferred amount of the colloidal silver is 1 x 10 -4 to 3 x 10 -1 mol per mol of light-sensitive silver halide. The mean grain size of the colloidal silver is from 0.005 to 0.2 µm. The electron donor-releasing coupler as described in means (8) is described in JP-A-61-102646, JP-A-61-13060, and JP-A-61-84646 (corresponding to U.S. Patent 4,741,994). There is, for example, the following compound: The electron donor-releasing coupler of means (8) may be incorporated into at least one of light-sensitive layers and light-insensitive layers, and it is preferably incorporated into a light-sensitive silver halide emulsion layer.

A typical material may comprise a support having thereon the above-described light-sensitive silver halide emulsion layers, in which at least one of the light-sensitive layers comprises two or more emulsion layers having substantially the same color sensitivity to blue light, green light or red light but different photosensitivity (hereinafter referred to as a unit light-sensitive layer). Multi-layer silver halide color photographic materials generally comprise a support having thereon a red-sensitive unit layer nearest to the support, a green-sensitive unit layer, and a blue-sensitive unit layer in this order. Depending on the end use, the above order of layers may be altered, or two layers having the same color sensitivity may have therebetween a layer having different color sensitivity. A light-insensitive layer, including various intermediate layers, may be provided between these silver halide light-sensitive layers or as an uppermost or undermost layer. Such intermediate layers may contain couplers and DIR compound as described in JP-A-61-43748, JP-A-59-113438, JP-A-59-113440, JP-A-61-20037, and JP-A-61-20038 and may also contain a color mixing inhibitor as is known in the art. Each unit light-sensitive layer preferably has a two-layer structure composed of a high sensitivity layer and a low sensitivity layer as described in West German Patent 1,121,470 and British Patent 923,045. The two layers of each unit light-sensitive layer are generally provided in a descending order of photosensitivity toward the support. Between the two silver halide emulsion layers, a light-insensitive layer may be provided. It is also possible to provide a low sensitivity emulsion layer on the side farther from the support and a high sensitivity emulsion layer on the side closer to the support as described in JP-A-57-112751, JP-A-62-200350, JP-A-62-206541, and JP-A-62-206543.

Further, a unit light-sensitive layer may be composed of three layers whose photosensitivity differs in a descending order toward the support, i.e., the highest sensitivity silver halide emulsion layer as the upper layer, a middle sensitivity silver halide emulsion layer as an intermediate layer, and the lowest sensitivity silver halide emulsion layer as the lower layer, as proposed in JP-B-49-15495. Three layers of different sensitivity may also be arranged in an order of middle sensitivity emulsion layer/high sensitivity emulsion layer/low sensitivity emulsion layer/support as described in JP-A-59-202464. In addition, an order of high sensitivity emulsion layer/low sensitivity emulsion layer/middle sensitivity emulsion layer or an order of low sensitivity emulsion layer/middle sensitivity emulsion layer/high sensitivity emulsion layer can also be used. Where a unit light-sensitive layer is composed of four or more layers, the order of layers can be similarly altered.

Such tabular grains can easily be prepared by the processes described, e.g., in Gutoff, Photographic Science and Engineering, Vol. 14, pp. 248-257 (1970), U.S. Patents 4,434,226, 4,414,310, 4,433,048, and 4,439,520, and British Patent 2,112,157. The silver halide grains may be homogeneous grains having a uniform crystal structure throughout the individual grains or heterogeneous grains including those in which the inner portion and the outer portion have different halogen compositions, those in which the halogen composition differs among these portions, and those having silver halide of different halogen composition fused thereto through epitaxy. Silver halide grains fused with compounds other than silver halides, e.g., silver rhodanide or lead oxide, may also be used. A mixture comprising grains of various crystal forms is employable. The photographic emulsions may be either of surface latent image type which forms a latent image predominantly on the grain surface, of internal latent image type which forms a latent image predominantly in the inside of grains, or of a type which forms a latent image both on the grain surface and in the inside of grains, but should be of negative type. The internal latent image type emulsion may be a core/shell type internal latent image type emulsion as described in JP-A-63-264740. Preparation of such a core/shell type internal latent image type emulsion is described in JP-A-59-133542. The thickness of the outer shell of this type preferably ranges from about 3 to about 40 nm, and more preferably from 5 to 20 nm, but may vary depending on the development processing conditions, among other factors. Silver halide emulsions are usually subjected to physical ripening, chemical ripening, and spectral sensitization. Additives to be used in these steps are described in Research Disclosure (hereinafter abbreviated as RD ) Nos. 17643, 18716 and 307105 as summarized in Table hereinafter described. In the light-sensitive material of the present invention, a mixture of two or more light-sensitive emulsions differing in at least one characteristic including grain size, grain size distribution, halogen composition, grain form, and sensitivity can be used in the same layer. In the present invention, light-insensitive silver halide fine grains are preferably used. The terminology "light-insensitive silver halide fine grains" as used herein means silver halide fine grains which are not sensitive to light of imagewise exposure for obtaining a color image and are therefore not substantially developed during development processing. It is preferable that the light-insensitive silver halide fine grains are not previously fogged. The silver halide fine grains are preferably incorporated into a light-insensitive hydrophilic colloid layer, and more preferably they are incorporated into a layer which is present at the most far away position from the support than the light-sensitive layer which is present at the most far away position from the support. The silver halide fine grains have a silver bromide content of from 0 to 100 mol% and may contain, if desired, silver chloride and/or silver iodide. The silver halide fine grains preferably have a silver iodide content of from 0.5 to 10 mol% and a silver chloride content of not more than 30 mol%. The silver halide fine grains preferably have a mean particle size (an average circle-equivalent diameter of the projected area) of from 0.01 to 0.5 µm, and more preferably from 0.02 to 0.2 µm. The silver halide fine grains can be prepared in the same manner as for general light-sensitive silver halide grains. The surface of silver halide grains formed does not need to be either optically sensitized or spectrally sensitized. It is preferable, however, that a known stabilizer, such as triazole compounds, azaindene compounds, benzothiazolium compounds, mercapto compounds, and zinc compounds, be added before the silver halide fine grains are added to a coating composition. The layer containing the silver halide fine grains preferably contains colloidal silver. The light-sensitive material of the present invention preferably has a silver coverage (the total silver content including all silver amount in silver compounds and metal silver such as silver in light-sensitive and insensitive silver halide and colloidal silver) of not more than about 6.0 g/m 2 , and more preferably not more than about 5.5 g/m 2 . Known photographic additives which can be used in the present invention are described in the above-described RD Nos. 17643, 18716, and 30710 supra as tabulated below. In order to prevent photographic performance deterioration due to contact with formaldehyde gas, the light-sensitive material of the present invention preferably contains a compound capable of reacting with formaldehyde to fix it as described in U.S. Patents 4,411,987 and 4,435,503. In order to increase the interimage effects, a mercapto compound as described in U.S. Patents 4,740,454 and 4,788,132, JP-A-62-18539 (corresponding to U.S. Patent 4,740,454), and JP-A-1-283551 is preferably added to the light-sensitive material of the present invention. The light-sensitive material can further contain a compound capable of releasing a fogging agent, a development accelerator, a silver halide solvent, or a precursor of these compounds irrespective of the amount of developed silver as described in JP-A-1-106052. The light-sensitive material preferably contains a dye dispersed by the process described in WO 88/04794 and Published PCT Application (in Japan) 1-502912 or a dye described in EP 317308A, U.S. Patent 4,420,555 and JP-A-1-259358.

Examples of suitable couplers which imagewise release a nucleating agent or a development accelerator at the time of development are described in British Patents 2,097,140 and 2,131,188, JP-A-59-157638, and JP-A-59-170840. Compounds which release a fogging agent, a development accelerator, a silver halide solvent, among other components, upon oxidation-reduction reaction with an oxidation product of a developing agent as described in JP-A-60-107029, JP-A-60-252340, JP-A-1-44940, and JP-A-1-45687 are also preferably used. Other compounds which can be used in the light-sensitive material of the present invention include competing couplers as described in U.S. Patent 4,130,427; poly-equivalent couplers as described in U.S. Patents 4,283,472, 4,338,393, and 4,310,618; couplers capable of releasing a DIR redox compound, a DIR coupler-releasing couplers, a DIR coupler-releasing redox compound, or a DIR redox-releasing redox compound as described in JP-A-60-185950 and JP-A-62-24252; couplers capable of releasing a dye which restores its color after release as described in EP 173,302A and EP 313,308A; couplers capable of releasing a bleaching accelerator as described in RD, No. 11449, RD, No. 24241, and JP-A-61-201247; couplers capable of releasing a ligand as described in U.S. Patent 4,555,477; couplers capable of releasing a leuco dye as described in JP-A-63-75747; and couplers capable of releasing a fluorescent dye as described in U.S. Patent 4,774,181. These couplers are introduced into photographic materials by various known dispersion methods. High-boiling organic solvents which are useful in an oil-in-water type dispersion method are described, e.g., in U.S. Patent 2,322,027. Specific examples of the high-boiling organic solvents having a boiling point of 175°C or higher under atmospheric pressure are phthalic esters (e.g., dibutyl phthalate, dicyclohexyl phthalate, di-2-ethylhexyl phthalate, decyl phthalate, bis(2,4-di-t-amylphenyl) phthalate, bis(2,4-di-t-amylphenyl) isophthalate, bis(1,1-diethylpropyl) phthalate), phosphoric or phosphonic esters (e.g., triphenyl phosphate, tricresyl phosphate, 2-ethylhexyldiphenyl phosphate, tricyclohexyl phosphate, tri-2-ethylhexyl phosphate, tridodecyl phosphate, tributoxyethyl phosphate, trichloropropyl phosphate, di-2-ethylhexylphenyl phosphonate), benzoic acid esters (e.g., 2-ethylhexyl benzoate, dodecyl benzoate, 2-ethylhexyl p-hydroxybenzoate), amides (e.g., N,N-diethyldodecanamide, N,N-diethyllaurylamide, N-tetradecylpyrrolidone), alcohols or phenols (e.g., isostearyl alcohol, 2,4-di-t-amylphenol), aliphatic carboxylic acid esters (e.g., bis(2-ethylhexyl) sebacate, dioctyl azelate, glycerol tributyrate, isostearyl lactate, trioctyl citrate), aniline derivatives (e.g., N,N-dibutyl-2-butoxy-5-t-octylaniline), and hydrocarbons (e.g., paraffin, dodecylbenzene, diisopropylnaphthalane). Organic solvents having a boiling point of not lower than about 30°C, and preferably from about 50°C to about 160°C may be used in combination as an auxiliary solvent. Typical examples of such an auxiliary solvent are ethyl acetate, butyl acetate, ethyl propionate, methyl ethyl ketone, cyclohexanone, 2-ethoxyethyl acetate, and dimethylformamide. With respect to a latex dispersion method, the steps involved, the effects, and specific examples of loadable latices are described in U.S. Patent 4,199,363 and West German Patent (OLS) Nos. 2,541,274 and 2,541,230. The color light-sensitive material of the present invention preferably contains various antiseptic agents or antifungal agents, such as phenethyl alcohol and those described in JP-A-63-257747, JP-A-62-272248 and JP-A-1-80941 (e.g., 1,2-benzisothiazolin-3-one, n-butyl p-hydroxybenzoate, phenol, 4-chloro-3,5-dimethylphenol, 2-phenoxyethanol, and 2-(4-thiazolyl)benzimidazole). Suitable supports which can be used in the color light-sensitive materials are described, e.g., in RD, No. 17632, p. 28, RD , No. 18716, pp. 647 (right column) to 648 (left column), and RD , No. 307105, p. 879. In the light-sensitive material of the present invention, the hydrophilic colloidal layers on the side having emulsion layers preferably have a total film thickness of not more than about 28 µm, more preferably not more than 23 µm, even more preferably not more than 18 µm, and most preferably not more than 16 µm, and a rate of swell T 1/2 of not more than about 30 seconds, and more preferably not more than 20 seconds. The terminology "total film thickness" as used herein means a total film thickness as measured after conditioning at 25°C and a relative humidity of 55% for 2 days. The terminology "rate of swell T 1/2 " means the time required for a light-sensitive material to be swollen to 1/2 the saturated swollen thickness, the saturated swollen thickness being defined to be 90% of the maximum swollen thickness which is reached when the color light-sensitive material is swollen with a color developing solution at 30°C for 3 minutes and 15 seconds. The rate of swell can be determined by methods known in the art using, for example, a swellometer of the type described in A. Green, et al., Photographic Science and Engineering, Vol. 19, No. 2, pp. 124-129. The rate of swell T 1/2 can be controlled by adding a hardening agent for a gelatin binder or by varying aging conditions after coating. Further, the light-sensitive material preferably has a degree of swelling of from about 150 to about 400%. The terminology "degree of swelling" as used herein means the value obtained from the maximum swollen film thickness as defined above according to formula: (maximum swollen film thickness - film thickness)/film thickness. The light-sensitive material of the present invention preferably has at least one hydrophilic colloidal layer having a total dry film thickness of from about 2 to about 20 µm on the side opposite to photographic emulsion layers (hereinafter referred to as backing layer). The backing layer preferably contains the above-enumerated additives, such as light absorbents, filter dyes, ultraviolet absorbents, antistatic agents, hardening agents, binders, plasticizers, lubricants, coating aids, and surface active agents. The backing layer preferably has a degree of swelling of from about 150 to about 500%. A color developing solution to be used for developing the light-sensitive material according to the present invention is preferably an alkaline aqueous solution containing an aromatic primary amine color developing agent. Useful color developing agents include aminophenol compounds and preferably p-phenylenediamine compounds. Typical examples of p-phenylenediamine compounds are 3-methyl-4-amino-N,N-diethylaniline, 3-methyl-4-amino-N-ethyl-N-β-hydroxyethylaniline, 3-methyl-4-amino-N-ethyl-N-β-methanesulfonamidoethylaniline, 3-methyl-4-amino-N-ethyl-β-methoxyethylaniline, and salts thereof (e.g., sulfates, chlorides, and p-toluenesulfonates), with 3-methyl-4-amino-N-ethyl-N-β-hydroxyethylaniline sulfate being more preferred. These developing agents may be used either individually or in combination of two or more thereof according to the purpose. The color developing solution usually contains a pH buffering agent, e.g., carbonates, borates or phosphates of alkali metals, and a development inhibitor or an antifoggant, e.g., chlorides, bromides, iodides, benzimidazoles, benzothiazoles, and mercapto compounds. If desired, the color developing solution further contains various preservatives, such as hydroxylamine, diethylhydroxylamine, sulfites, hydrazines (e.g., N,N-biscarboxymethylhydrazine), phenyl semicarbazides, triethanolamine, catecholsulfonic acids; organic solvents, e.g., ethylene glycol and diethylene glycol; development accelerators, e.g., benzyl alcohol, polyethylene glycol, quaternary ammonium salts, and amines; dye-forming couplers; competing couplers; auxiliary developing agents, e.g., 1-phenyl-3-pyrazolidone; viscosity-imparting agents; and various chelating agents, such as aminopolycarboxylic acids, aminopolyphosphonic acids, alkylphosphonic acids; and phosphonocarboxylic acids (e.g., ethylenediaminetetraacetic acid, nitrilotriacetic acid, ethylenetriaminepentaacetic acid, diaminetetraacetic acid, hydroxyethyliminodiacetic acid, 1-hydroxyethylidene-1,1-diphosphonic acid, nitrilo-N,N,N-trimethylenephosphonic acid, ethylenediamine-N,N,N,N-tetramethylenephosphonic acid, ethylenediamine-di(o-hydroxyphenylacetic acid), and salts thereof). Processing steps and processing solutions other than the color developing solution for processing the color reversal light-sensitive materials of the present invention will be explained below. Of the processing steps involved, steps of from black-and-white (B/W) development through color development can be carried out by any of the following methods. 1) B/W development-washing-reversing-color development 2) B/W development-washing-light reversing-color development 3) B/W development-washing-color development The washing step in (1) to (3) may be replaced by rinsing as described in U.S. Patent 4,804,616 to thereby simplify processing and reduce waste liquor. Steps subsequent to color development can be carried out in any of the following manners. 4) Color development-conditioning-bleach-fixing-washing-stabilization 5) Color development-washing-bleach-fixing-washing-stabilization 6) Color development-conditioning-bleach-washing-fixing-washing-stabilization 7) Color development-washing-bleach-washing-fixing-washing-stabilization 8) Color development-bleach-fixing-washing-stabilization 9) Color development-bleach-blix (bleach-fix)-washing-stabilization 10) Color development-bleach-blix-fixing-washing-stabilization 11) Color development-bleach-washing-fixing-washing-stabilization 12) Color development-conditioning-blix-washing-stabilization 13) Color development-washing-blix-washing-stabilization 14) Color development-blix-washing-stabilization 15) Color development-fixing-blix-washing-stabilization The washing immediately preceding stabilization in (4) to (15) above may be omitted, or alternatively, the final stabilization may be omitted. Any one of (1) to (3) is followed by any one of (4) to (15) to accomplish color reversal processing. A B/W developing solution to be used for B/W development contains one or more of known developing agents, such as dihydroxybenzenes (e.g., hydroquinone), 3-pyrazolidones (e.g., 1-phenyl-3-pyrazolidone), aminophenols (e.g., N-methyl-p-aminophenol), 1-phenyl-3-pyrazolines, ascorbic acid, and heterocyclic compounds comprised of a 1,2,3,4-tetrahydroquinoline ring fused to an indolene ring as described in U.S. Patent 4,067,872. If desired, the B/W developing solution may further contain preservatives (e.g., sulfites and bisulfites), buffering agents (e.g., carbonates, boric acid, borates, and alkanolamines), alkali agents (e.g., hydroxides and carbonates), dissolving aids (e.g., polyethylene glycols and esters thereof), pH adjusting agents (e.g., acetic acid or a similar organic acid), sensitizers (e.g., quaternary ammonium salts), development accelerators, surface active agents, defoaming agents, hardening agents, viscosity-imparting agents, and so on. The B/W developing solution should contain a compound acting as a silver halide solvent. A sulfite added as a preservative as mentioned above usually serves as a silver halide solvent. Specific examples of suitable sulfites and other usable silver halide solvents are KSCN, NaSCN, K 2 SO 3 , Na 2 SO 3 , K 2 S 2 O 5 , Na 2 S 2 O 5 , K 2 S 2 O 3 , and Na 2 S 2 O 3 . The pH of the thus prepared B/W developing solution is adjusted so as to provide desired density and contrast, usually within a range of from about 8.5 to about 11.5. Sensitizing treatment by using such a B/W developing solution can usually be effected by extending the developing time to up to about three times the time required for standard processing. The time extension for high speed development can be shortened by elevating the processing time. The color developing solution in color reversal development generally have a pH of from about 10 to about 12. A rate of replenishment for these developing solutions is usually about 3 ℓ or less per m 2 of a light-sensitive material, but varies depending on the kind of the light-sensitive material. The replenishment rate may be reduced to about 500 mℓ/m 2 or less by reducing a bromide ion concentration in the replenisher. In the case of reducing the replenishment rate, it is preferable to prevent evaporation or aerial oxidation of the processing solution by minimizing the liquid surface area of the processing tank in contact with air. The contact area between a photographic processing solution and air can be expressed in terms of opening ratio calculated by dividing a contact area (cm 2 ) of the processing solution with air by a volume (cm 3 ) of the processing solution. The opening ratio as defined above is preferably about 0.1 or less, and more preferably between 0.001 and 0.05. The opening ratio of the processing tank can be adjusted by, for example, putting a barrier, such as a floating cover, on the liquid surface, using a movable cover as described in JP-A-1-82033, or utilizing slit development processing as described in JP-A-63-216050. Reduction of the opening ratio is preferably applied to not only color development and B/W development but also all the subsequent steps, such as bleach, blix, fixing, washing, and stabilization. Reduction of a replenishment rate may also be achieved by using a means for suppressing accumulation of a bromide ion in the developing solution. A reversing bath which can be used after B/W development can contain known fogging agents, such as stannous ion complex salts, e.g., a stannous ion-organic phosphoric acid complex salt (see U.S. Patent 3,617,282), a stannous ion-organic phosphonocarboxylic acid complex salt (see JP-B-56-32616), a stannous ion-aminopolycarboxylic acid complex salt (see U.S. Patent 1,209,050); and boron compounds, e.g., boron hydride compounds (see U.S. Patent 2,984,567) and heterocyclic aminoboran compounds (see British Patent 1,011,000). The fogging (reversing) bath has a broad pH range from an acidic to alkaline sides, usually ranging from about 2 to about 12, preferably from 2.5 to 10, and more preferably from 3 to 9. Processing with the reversing bath may be replaced by re-exposure for light reversing. Further, the reversing step may be omitted by adding the above-described fogging agent to a color developing solution. After color development, the light-sensitive material is subjected to bleach or blix. Bleach or blix may be conducted directly after color development, or an extra step, such as stopping, conditioning, washing and the like, may be inserted between color development and bleach or blix for the purpose of preventing unnecessary after-development or aerial fog and reducing the amount of a color developing solution carried over into a desilvering step or for the purpose of washing away sensitizers or dyes present in the light-sensitive material and the color developing agent impregnated into the light-sensitive material. The photographic emulsion layers after color development are usually subjected to bleach. Bleach and fixing may be carried out either simultaneously (blix) or separately. For rapid processing, bleach may be followed by blix. Further, the mode of desilvering can be arbitrarily selected according to the end use. For example, blix may be effected using two tanks connected, or fixing may be followed by blix, or blix may be followed by bleach. Bleaching agents to be used include compounds of polyvalent metals, e.g., iron (III), peracids, quinones, and nitro compounds. Typical bleaching agents include organic complex salts of iron (III), e.g., complex salts with aminopolycarboxylic acids (e.g., ethylenediaminetetraacetic acid, diethylenetriaminepentaacetic acid, cyclohexanediaminetetraacetic acid, methyliminodiacetic acid, 1,3-diaminopropanoltetraacetic acid, glycol ether diaminetetraacetic acid) or organic acids (e.g., citric acid, tartaric acid, and malic acid). Preferred agents are aminopolycarboxylic acid iron (III) complexes, e.g., (ethylenediaminetetraacetato)iron (III) salts and (1,3-diaminopropanetetraacetato)iron(III) salts, from the standpoint of rapidness of processing and prevention of environmental pollution. Aminopolycarboxylic acid iron (III) complex salts are particularly useful either in a bleaching bath or in a blix monobath. A bleaching bath or blix bath containing these aminopolycarboxylic acid iron (III) complex salts usually has a pH between 4.0 and 8.0. A lower pH is also employed for rapid processing. If desired, a fixing bath, a blix bath, or a prebath thereof may contain known bleaching accelerators. Useful bleaching accelerators include compounds having a mercapto group or a disulfide group as described in U.S. Patent 3,893,858, German Patents 1,290,812 and 2,059,988, JP-A-53-32736, JP-A-53-57831, JP-A-53-37418, JP-A-53-72623, JP-A-53-95630, JP-A-53-95631, JP-A-53-104232, JP-A-53-124424, JP-A-53-141623, JP-A-53-28426, RD , No. 17129 (Jul., 1978); thiazolidine derivatives as described in JP-A-50-140129; thiourea derivatives as described in JP-B-45-8506, JP-A-52-20832, JP-A-53-32735, and U.S. Patent 3,706,561; iodides as described in West German Patent 1,127,715 and JP-A-58-16235; polyoxyethylene compounds as described in German Patents 966,410 and 2,748,430; polyamine compounds described in JP-B-45-8836; compounds described in JP-A-49-40943, JP-A-49-59644, JP-A-53-94927, JP-A-54-35727, JP-A-55-26506, and JP-A-58-163940; and a bromide ion. Among them, compounds having a mercapto group or a disulfide group are preferred because of their high accelerating effect. The compounds disclosed in U.S. Patent 3,893,858, West German Patent 1,290,812, and JP-A-53-95630 are particularly preferred. In addition, the compounds disclosed in U.S. Patent 4,552,834 are also preferred. These bleaching accelerators may be incorporated into a light-sensitive material. The bleaching accelerators are particularly effective for blix of color light-sensitive materials for photographing. For the purpose of preventing bleach stain, the bleaching or blix bath preferably contains an organic acid. More preferred organic acids which can be used are those having an acid dissociation constant (pKa) of from about 2 to about 5, e.g., acetic acid and propionic acid. Fixing agents which can be used in a fixing or blix bath include thiosulfates, thiocyanates, thioether compounds, thioureas, and a large quantity of an iodide, with thiosulfates being commonly employed. Aammonium thiosulfate is preferred. A combined use of a thiosulfate and a thiocyanate, a thioether compound, a thiourea, etc. is also preferred. Preservatives for the fixing or blix bath preferably include sulfites, bisulfites, carbonyl-bisulfite adducts, and sulfinic acid compounds described in EP 294769A. The fixing or blix bath preferably contains various aminopolycarboxylic acids or organophosphonic acids for stabilization. The total time of desilvering is preferably as short as possible as long as insufficient desilvering does not result. A preferred desilvering time is from about 1 to about 3 minutes, and more preferably from 1 to 2 minutes. The desilvering temperature is from about 25 to about 50°C, and preferably from 35 to 45°C. In the preferred temperature range, the rate of desilvering is improved, and stain formation after processing is effectively prevented. It is perferable that desilvering should be performed while reinforcing stirring as much as possible. Methods for achieving reinforced stirring include a method in which a jet stream of a processing solution is made to strike against the surface of the emulsion layer as described in JP-A-62-183460; a method of using a rotating means to enhance stirring effects as described in JP-A-62-183461; a method in which a light-sensitive material is moved with its emulsion surface in contact with a wire blade placed in a processing solution to make turbulence; and a method of increasing a total flow of a circulating processing solution. These stirring means are effective in any of a bleaching bath, a blix bath and a fixing bath. Reinforced stirring appears to accelerate supply of a bleaching agent or a fixing agent to emulsion layers and, as a result, to increase the rate of desilvering. The above-described means for reinforced stirring is more effective in the case where a bleaching accelerator is used, markedly enhancing acceleration effects and eliminating the fixing inhibitory effect of the bleaching accelerator. An automatic developing machine which can be used for processing the light-sensitive material preferably has a means for carrying a light-sensitive material as described in JP-A-60-191257, JP-A-60-191258, and JP-A-60-191259. As mentioned in JP-A-60-191257 supra , such a carrying means is highly effective to considerably reduce carry-over of a processing solution from a prebath into a succeeding bath thereby preventing reduction of processing capacity. These means are particularly effective for reduction of processing time or replenishment rate in each processing step. The silver halide color light-sensitive material after desilvering is generally subjected to washing and/or stabilization. The amount of washing water to be used in the washing step is selected from a broad range depending on characteristics of the light-sensitive material (e.g., the kind of photographic materials such as couplers), the end use of the light-sensitive material, the temperature of washing water, the number of washing tanks (the number of stages), the replenishing system (e.g., counter-flow system or direct-flow system), and other various conditions. For example, a relationship between the number of washing tanks and the quantity of water in a multi-stage counter-flow system can be obtained by the method described in Journal of the Society of Motion Picture and Television Engineers , Vol. 64, pp. 248-253 (May, 1955). According to the disclosed multi-stage counter-flow system, a requisite amount of water can be greatly reduced. On the other hand, bacteria tend to grow in the tank with an increase in water retention time, and suspended bacterial cells adhere to light-sensitive materials. Such a problem can be effectively coped with by adopting a method of reducing calcium and magnesium ions of washing water as described in JP-A-62-288838. It is also effective to use bactericides, such as isothiazolone compounds or thiabendazole compounds as described in JP-A-57-8542; chlorine type bactericides, e.g., chlorinated sodium isocyanurate; and other bactericides described in Horiguchi Hiroshi, Bokin bobaizai no kagaku , Sankyo Shuppan (1986), Eisei Gijutsukai (ed.), Biseibutsu no mekkin, sakkin, bobai gijutsu , Kogyo Gijutsukai (1982), and Nippon Bokin Bobai Gakkai (ed.), Bokin bobaizai jiten (1986), e.g., benzotriazole. Washing water has a pH usually between about 4 and about 9, and preferably between 5 and 8. Washing conditions, though varying depending on the characteristics or the end use of the light-sensitive material and the like, are usually from about 15 to about 45°C in temperature and from about 20 seconds to about 10 minutes in time, and preferably from 25 to 40°C in temperature and from 30 seconds to 5 minutes in time. The washing step may be followed by or replaced with stabilization processing. Where stabilization is conducted in place of washing, any known stabilizing techniques described, e.g., in JP-A-57-8543, JP-A-58-14834, and JP-A-60-220345 can be utilized. Where washing is followed by stabilization, a stabilizing bath to be used includes a solution containing a dye stabilizer and a surface active agent, which is used as a final bath for color light-sensitive materials for shooting. Suitable dye stabilizers include aldehydes, e.g., formalin and glutaraldehyde, N-methylol compounds, hexamethylenetetramine, and an aldehyde-sulfite adduct. If desired, the stabilizing bath may also contain various chelating agents and antifungal agents. An overflow accompanying replenishment for washing and/or stabilization may be reused in other processing steps, such as a desilvering step. In cases where each processing solution is concentrated by vaporization during processing with an automatic developing machine, water is preferably supplied to the processing solution to correct the concentration. For the purpose of simplifying and speeding up processing, the silver halide color light-sensitive material may contain therein a color developing agent, preferably in the form of a precursor thereof. Examples of color developing agent precursors include indoaniline compounds described in U.S. Patent 3,342,597, Schiff base compounds described in RD , Nos. 14850 and 15159, aldol compounds described in U.S. Patent 3,342,597, RD , No. 13924, metal complex salts described in U.S. Patent 3,719,492, and urethane compounds described in JP-A-53-135628. If desired, the silver halide color light-sensitive material may further contain therein various 1-phenyl-3-pyrazolidone compounds for the purpose of accelerating color development. Typical examples of these accelerators are described in JP-A-56-64339, JP-A-57-144547, and JP-A-58-115438. Each of the above-described processing solutions is used at a temperature of from about 10 to about 50°C and, in a standard manner, from about 33 to about 38°C. Higher processing temperatures may be employed for reducing processing time, or lower temperatures may be employed for improving image quality or stability of the processing solution. The present invention is now illustrated in greater detail by way of the following Examples, but it should be understood that the present invention is not deemed to be limited thereto.

An inernally-fogged silver halide emulsion (designated Emulsion B) was prepared by depositing silver bromide on the surface of grains of Emulsion A thus obtained to form an outer shell having a thickness of 50 Å. Compounds used in the sample preparation are as follows. Oil-1 Dibutyl phthalate Oil-2 Tricresyl phosphate Preparation of Sample 102: Sample 102 was prepared in the same manner as for Sample 101, except for changing the silver iodide content of the light-sensitive silver halide emulsion of the 4th, 5th, 6th, 9th, 10th, 11th, 15th, 16th, and 17th layers to 7.0 mol%, 6 mol%, 5 mol%, 6.5 mol%, 5.5 mol%, 5.0 mol%, 5 mol%, 6 mol%, and 6.5 mol%, respectively.

The interimage effects exercised on the red-sensitive emulsion layers and green-sensitive emulsion layers in Samples 101 to 117 were determined by the above-described method, and the results obtained are shown in Table 2 below. In the determination, development processing was carried out according to the procedures described below. Each of Samples 101 to 117 was cut to films having a size of 10 × 12.5 cm 2 (4 × 5 in 2 ). The following objects were prepared.

Formalin (37%) 5.0 ml Polyoxyethylene-p-monononylphenyl ether (average degree of polymerization: 10) 0.5 ml Water to make 1000 ml pH not adjusted The results of Table 2 prove the followings: 1) Even with interimage effect-producing means (1) being provided, the interimage effect produced does not satisfy relationships (a) or (b) unless at least one of means (2) to (8) is used (compare Sample 101 with Samples 102 and 103). 2) Even with at least one of interimage effect-producing means (2) to (8) being provided, the interimage effect produced does not satisfy relationships (a) or (b) unless means (1) is provided, or unless the total light-sensitive silver halide emulsion has an average silver iodide content of not more than 5.5 mol% (Samples 104 and 105). 3) If ▵logE(R 0.5 ) or ▵logE(G 0.5 ) is smaller than the respective range as specified in relationships (a) or (b), saturation of a color image becomes low (Samples 101 to 105). 4) If ▵logE(R 0.5 ) or ▵logE(G 0.5 ) is smaller than the respective range as specified in relationships (a) or (b) and, also, if (▵logE(R 0.5 ) - ▵logE(R 1.5 )) or (▵logE(G 0.5 ) - ▵logE(G 1.5 )) is smaller than the respective range as specified by relationships (a) or (b), a color image has reduced saturation and a poor description of the shade (Samples 101 to 102 and 105). 5) Even with interimage effect-producing means (1) and at least one of means (2) to (8) being provided, an excessive interimage effect exercised on the high density area causes ▵logE(R 1.5 ) or ▵logE(G 1.5 ) to exceed the respective range as specified by relationships (a) or (b) and (▵logE(R 0.5 ) - ▵logE(R 1.5 )) or (▵logE(G 0.5 ) - ▵logE(G 1.5 )) to become smaller than the respective range as specified by relationships (a) or (b). As a result, high saturation can be obtained, but a description of the shade is deteriorated (Sample 116). 6) Even with interimage effect-producing means (1) and at least one of means (2) to (8) being provided, an excessive interimage effect exercised on the low density area causes ▵logE(R 0.5 ) or ▵logE(G 0.5 ) to exceed the respective range as specified by relationships (a) or (b) and (▵logE(R 0.5 ) - ▵logE(R 1.5 )) or (▵logE(G 0.5 ) - ▵logE(G 1.5 )) to become greater than the respective range as specified by relationships (a) or (b). As a result, high saturation can be obtained, but a description of the shade is deteriorated (Sample 117). 7) When interimage effect-producing means (1) and at least one of means (2) to (8) are provided to produce a proper interimage effect, the interimage effect produced be able to be fallen within the range specified by relationships (a) or (b). With these conditions being fulfilled, both high saturation and a satisfactory description of the shade can be obtained (Samples 106 to 115).
