Description: FIELD OF THE INVENTION The present invention relates to a process for developing silver halide color reversal photographic materials excellent in color reproducibility. BACKGROUND OF THE INVENTION Usually, a color reversal photographic material has a plurality of silver halide emulsion layers different in color sensitivity such as a red sensitive layer, a green sensitive layer and a blue sensitive layer on a support. The color reversal photographic material which has been image exposed to a polychromatic object is first subjected to black-and-white silver development at a first developing stage, and then the residual silver halide is color developed at a second developing stage through a chemical or optical fogging stage to form cyan, magenta and yellow color images. A dye image usually formed on each color sensitive layer by polychromatic exposure is different from a dye image produced by monochromatic exposure. In the case of the color reversal photographic material, this difference is mainly caused by the transfer of a development restrainer such as iodine ions generated between the emulsion layers different in color sensitivity at the black-and-white developing stage. The dye image difference between the polychromatic exposure and the monochromatic exposure caused by such development is called a multilayer effect or an inter image effect as described in Hudson and Horton, Journal of the Optical Society of America 42 (No. 9), pp. 663 to 669 (1976), and known to be available for improving sharpness and color reproducibility. As a technique to enhance the multilayer effect, JP-A-51-128528 (the term "JP-A" as used herein means an "unexamined published Japanese patent application") discloses a process for enhancing the multilayer effect given to a sensitive silver halide emulsion layer by introducing an emulsion which has fogged the surfaces of silver halide grains into the sensitive silver halide emulsion layer. Research Disclosure No. 13553 (1975) also discloses a process for application of the preferable multilayer effect by iodine ions in a color reversal photographic material, which comprises adding an emulsion containing a silver halide so as to release the iodine ion such as AgBrI, AgClI or AgBrClI to at least one layer to which the multilayer effect is applied, adding a hydrophilic colloid as well as usual emulsion grains to at least one layer to which the multilayer effect is given, and further adding another surface fogging emulsion. However, the above-described references do not fully disclose the features of the more preferred sensitive silver halide emulsion in enhancing the multi layer effect utilizing the fogging emulsion. At the black-and-white developing stage of the color reversal photographic materials the sensitive silver halide emulsion is developed depending on the amount of exposure. At that time, the silver halide emulsion grains not developed are subjected to the color developing processing through the fogging stage. This color developing stage is required to develop all the residual silver halide to develop color, so that its developing activity is designed to be high. For this reason, it is substantially almost impossible to make the multilayer effect function at the color developing stage, and, in the color reversal photographic materials, the multilayer effect is substantially determined by the black-and-white developing stage. At this black-and-white developing stage, the developing solution has the effect of dissolving the emulsion grains. This solubility is controlled by the iodine ions diffused by the development of the other layers, whereby the multilayer effect is obtained. Although the multilayer effect is produced according to many mechanisms, the most important mechanism of them is the above one. The emulsion dissolving effect of this developing solution is enhanced with increasing the developing time. Hence, when the processing time of the black-and-white developing stage is short, it is difficult to apply the sufficient multilayer effect to the conventional color reversal photographic materials, compared to the case in which the processing time is long. EP-A-0 272 675 describes a silver halide photographic material comprising a support having thereon at least one silver halide emulsion layer composed of one or more layers, wherein the silver halide emulsion contained in at least one layer of the silver halide emulsion layer is chemically sensitized so that silver halide grains in the emulsion have at least one maximum value of the latent image number in distribution thereof in the inside of the silver halide grains and the position where the maximum value(s) exists is at a depth of less than 0.01 µm from the surface of the grains, and the emulsion also has a latent image number of at least 1/5 of the largest maximum value but less than the largest maximum value on the surface of the grains. US-A-4 804 616 describes a method for continuously processing a color reversal photographic material. After black and white development, the color reversal photographic material is rinsed in a bath wherein the replenishing amount per unit area of the photographic material is 3 to 50 times as much as the amount of processing solution carried over from the preceding bath in terms of volume ratio and the pH is 9.5 or below. US-A-4 839 268 describes a silver halide color reversal photosensitive material comprising a plurality of silver halide emulsion layers on a substrate, wherein 50 % or more of the total projected area of silver halide grains contained in at least one of said silver halide emulsion layers is occupied by tabular silver iodobromide grains having an average thickness of 0.5 micron or less, an average diameter of 0.5 micron or more, an average aspect ratio of at least 5/1, and a silver iodide content of 4.0 mol % or less, and said tabular silver iodobromide grains are negative-type silver halide grains forming a latent image mainly inside the grains. SUMMARY OF THE INVENTION It is therefore an object of the present invention to provide a process giving the sufficient multilayer effect even in processing in which the black-and-white developing time is short. The object of the present invention is attained by a process for developing a silver halide color reversal photographic material comprising a support having provided thereon at least one red-sensitive silver halide emulsion layer, green-sensitive silver halide emulsion layer and blue-sensitive silver halide emulsion layer, wherein at least one silver halide emulsion layer contains tabular silver halide grains having an aspect ratio of at least 5 occupying at least 50% of all silver halide grains existing in the same layer as a projected area, and having a mean sphere-corresponding grain size of 0.30 µm or less, which comprises developing said color reversal photographic material with a black-and-white developing solution for 100 seconds or less. DETAILED DESCRIPTION OF THE INVENTION It is preferred that the mean sphere-corresponding grain size of the silver halide emulsion grains contained in at least one emulsion layer is 0.25 µm or less. The lower limit thereof is preferably 0.1 µm from the view point of sensitivity. The measuring methods of the mean sphere-corresponding grain size of silver halide grains are described in detail, for example, in James, The Theory of Photographic Process , the 4th edition, page 100. Such methods include methods using an optical microscope, an electron microscope and a coulter counter. When the size of such a degree as the size of the emulsion grains of the present invention is measured, a method is preferably used in which the thickness of the grains is determined from the projected area of the grains and the length of shadows obtained by shadowing, using an electron microscope, the volume of each grain is determined therefrom, and the mean sphere-corresponding grain size is determined from the mean value thereof. As the silver halide grains used in the present invention, monodisperse emulsions narrow in grain size distribution or polydisperse emulsions wide in grain size distribution may be used. In the present invention, at least one sensitive emulsion layer contains the tabular silver halide emulsion grains having a mean sphere-corresponding grain size of 0.30 µm or less and an aspect ratio of at least 5 so as to occupy at least 50% of all silver halide grains existing in the same layer as a projected area. It is further preferred that at least one layer contains tabular silver halide emulsion grains having an aspect ratio of at least 8 so as to occupy at least 50% of all silver halide grains existing in the same layer as a projected area. The aspect ratio called here means the ratio of diameter to thickness of the emulsion grain. Further, the diameter of the silver halide grain means the diameter of a circle whose area is the same as the projected area of the grain. In general, the tabular silver halide grain has two planes parallel to each other, and the thickness called here is represented by the distance between the two parallel planes constituting the tabular silver halide grain. Any of silver bromide, silver iodide, silver iodobromide, silver chlorobromide, silver chloroiodobromide and silver chloride may be used as the tabular silver halide grains. However, silver bromide and silver iodobromide are preferably used. In particular, it is preferred that silver iodobromide having a silver iodide content of 0.01 to 30 mol%, more preferably 0.5 to 10 mol%, is used. Methods for preparation of the tabular silver halide grains are hereinafter described. The tabular silver halide grains can be prepared by suitable combinations of methods known in the art. For example, the tabular silver halide grains can be obtained by simultaneous addition of silver and a halogen solution with maintaining the pBr value as relatively low as 1.3 or less. The size of the tabular silver halide grains can be adjusted by temperature control, selection of the kind or amount of solvent, selection of the kind of silver salt used on grain growth and control of the addition rate of the halide. When the tabular silver halide grains of the present invention is prepared, solvents for silver halides can be used as required. The solvents for silver halides frequently used include ammonia, thioethers and thiourea compounds. For the thioethers, reference can be made to U.S. Patents 3,271,157, 3,790,387 and 3,574,628. In addition, methods for preparation of the tabular silver halide grains are described in Gutoff, Photographic Science and Engineering , Vol. 14, pages 248 to 257 (1970), US-A-4,434,226, 4,414,310, 4,433,048 and 4,439,520 and GB-B-2,112,157. The above-described at least one sensitive emulsion layer means at least one layer of the red-sensitive emulsion layer, the green-sensitive emulsion layer and the blue-sensitive emulsion layer. Each of the above-described emulsion layers may consist of a plurality of layers having a similar spectral sensitivity as long as at least one of those layers meets the above-described requirements. However, a low-sensitive emulsion layer is preferably used from the viewpoint of sensitivity. When a layer having yellow colloidal silver is contained, it is preferred that an emulsion layer in most close proximity thereto meets the above-described requirements. This yellow colloidal silver is known to be prepared by various methods. S. Inoue, Preparative Experiments of Inorganic Chemistry , page 647 discloses the method of reducing silver nitrate with dextrin under alkaline conditions, the method of reducing silver nitrate with tannin under alkaline conditions, the method of reducing silver nitrate with hydrazine and the method of reducing silver oxide with sodium carbonate and hydrogen peroxide in the presence of a silver sol reduced with phosphorus. Silver halide grains used in the present invention, other than the tabular silver halide grains which have a mean sphere-corresponding grain size of 0.30 µm or less and an aspect ratio of at least 5, are hereinafter described. The silver halide grains may have a regular crystal form such as a cubic, an octahedral or a tetradecahedral form, an irregular crystal form such as a spherical or a tabular form, crystalline defects such as a twin plane, or a composite form thereof. The silver halide grains may be fine grains having a grain size of about 0.2 µm or less or large sized grains having a projected area diameter of up to about 10 µm. The silver halide grains may be used as a monodisperse emulsion or a polydisperse emulsion. A monodisperse emulsion having a coefficient of variation of not more than 20% is preferably used. Such photographic silver halide emulsions can be prepared by using the methods described in Research Disclosure No. 17643, pages 22 and 23, I.

The crystal structure may be uniform, or the interior and the exterior of the grain may be composed of different halogen compositions, respectively. The crystal structure may also be a laminar structure. Silver halides different in composition may be joined together by epitaxial junction. Further, silver halides may be joined to compounds other than silver halides, such as silver rhodanine and lead oxide. Mixtures of grains of various crystal forms may be used.

EXAMPLE 1 (Emulsion A) Cubic grains of silver iodobromide (silver iodide: 2.5 mol%) were prepared by the controlled double jet process in the presence of ammonia. The mean sphere-corresponding grain size of the resulting grains was 0.35 µm. The grains were subjected to chemical sensitization simultaneously using gold and sulfur. The emulsion thus obtained was named Emulsion A. 60% by weight of the emulsion grains had grain sizes within 18% from the mean grain size.

(Emulsion C) To 1 ℓ of water were added 30 g of gelatin and 10.3 g of potassium bromide, and then Solutions I and II shown in Table 1 were simultaneously added thereto with stirring for 15 minutes in a vessel maintained at 60°C. In the resulting tabular silver halide grains, 53% of all grains as a projected area were composed of grains having an aspect ratio of at least 5, and the content of silver iodide was 2.5 mol%. This emulsion was subjected to chemical sensitization simultaneously using gold and sulfur. The tabular silver halide emulsion thus obtained was named Emulsion C. The grains of Emulsion C had a mean sphere-corresponding grain size of 0.35 µm.

Phenoxyethanol was added to Emulsions A to F as a preservative in an amount of 40,000 ppm based on gelatin. (Preparation of Photographic Material) A paper support both sides of which had been laminated with polyethylene was coated with the following first to twelfth layers to prepare a multilayer color photographic material, which was named Sample 101. Polyethylene on the side of the first layer to be coated contained titanium oxide as a white pigment and a slight amount of ultramarine as a bluing dye. The composition of each sensitive layer is shown below. Numerals for the components indicate coated amounts represented in g/m 2 .

One was exposed through an optical wedge using a white light source and the other was exposed through an optical wedge using a green light source. These exposed Samples were processed by the following processing procedure (I): (Processing Procedure (I)) First development (black-and-white development) 38°C 75 seconds Washing 38°C 90 seconds Reversal exposure 100 lux or more 1 second or more Color development 38°C 135 seconds Washing 38°C 45 seconds Bleach-fixing 38°C 120 seconds Washing 38°C 135 seconds (Composition of Processing Solutions) First Development Solution Pentasodium nitrilo-N,N,N-trimethylenephosphonate 0.6 g Pentasodium diethylenetriaminepentaacetate 4.0 g Potassium sulfite 30.0 g Potassium thiocyanate 1.2 g Potassium carbonate 35.0 g Potassium hydroquinonemonosulfonate 25.0 g Diethylene glycol 15.0 ml 1-Phenyl-4-hydroxymethyl-4-methyl-3-pyrazolidone 2.0 g Potassium bromide 0.5 g Potassium iodide 5.0 mg Water to make 1 ℓ (pH: 9.70) Color Developing Solution Benzyl alcohol 15.0 ml Diethylene glycol 12.0 ml 3,6-Dithia-1,8-octanediol 0.2 g Pentasodium nitrilo-N,N,N-trimethylene phosphonate 0.5 g Pentasodium diethylenetriaminepentaacetate 2.0 g Sodium sulfite 2.0 g Potassium carbonate 25.0 g Hydroxylamine sulfate 3.0 g N-Ethyl-N-(β-methanesulfonamidoethyl)-3-methyl-4-aminoaniline sulfate 5.0 g Potassium bromide 0.5 g Potassium iodide 1.0 mg Water to make 1 ℓ (pH: 10.40) Bleach-Fixing Solution After processing, sensitometry was conducted for magenta image formed on the above-described Samples. For each Sample, the sensitivity ratio of the magenta image of the test piece exposed to green light to the magenta image of the test piece exposed to white light was determined. The results are shown in Table 3. Then, Samples 101 to 107 were exposed in the same manner as described above, and processed by the following processing procedure (II). (Processing Procedure (II)) The same as with processing procedure (I) except the time of the first development (black-and-white development) was 55 seconds. The results are also shown in Table 3. Processing Procedure Sensitivity Ratio of Magenta Image Exposed to Green Light to That Exposed to White Light (at a density of 0.6) Sample No. Processing Time of Black-and-White Development (sec) 101 (Comparison) I 75 1.37 102 (Comparison) I 75 1.66 103 (Comparison) I 75 1.42 104 (Invention) I 75 1.79 105 (Invention) I 75 1.90 106 (Invention) I 75 2.01 107 (Invention) I 75 1.71 101 (Comparison) II 55 1.10 102 (Comparison) II 55 1.35 103 (Comparison) II 55 1.16 104 (Invention) II 55 1.51 105 (Invention) II 55 1.65 106 (Invention) II 55 1.77 107 (Invention) II 55 1.42 As the sensitivity ratio of monochromatic exposure to white light exposure is higher, the multilayer effect becomes larger, resulting in a color reversal photographic light-sensitive material showing color reproducibility of high chroma. As apparent from Table 3, when the form of the emulsion grains contained in the sixth layer is tabular, the multilayer effect is preferably enhanced. The smaller the mean sphere-corresponding grain size is and the higher the aspect ratio is, the higher effect is obtained. When the layer adjacent to the emulsion layer contains yellow colloidal silver, the multilayer effect is more enhanced compared with the case that the layer does not contain yellow colloidal silver. Further, the shorter the time of the black-and-white development is, the less the multilayer effect becomes. However, the effect of the present invention is remarkable when the time of the black-and-white development is short. According to the present invention, even in the processing in which the time of the first development is short, the color reversal photographic materials which give the sufficient multilayer effect are obtained.
