Title: Silver halide color photograph material and method for forming image using the same

Description:
FIELD OF THE INVENTION 
     The present invention relates to a silver halide color photographic material which is suitable for rapid processing and a method for forming an image using the same and, in particular, relates to a silver halide color photographic material which is improved in the upset of the balance of gradation due to shortening of the color development processing time, and which is capable of providing the same gradation in any processing now widely prevailing and rapid processing, and relates to a method for forming an image using the same. 
     BACKGROUND OF THE INVENTION 
     The development processing time of a color negative light-sensitive material has been extremely reduced by the introduction of C-41 processing by Eastman Kodak in 1972, and the wet processing time exclusive of drying process has been shortened to 17 minutes and 20 seconds. Further, in recent years, the wet processing time has been speeded up to 8 minutes and 15 seconds by the introduction of CN-16FA processing of Fuji Photo Film Co., Ltd. for a minilab market. 
     Even now when rapid processing has prevailed, finishing of printing of a negative light-sensitive material asked by a user requires 30 minutes or so even by the most quick finishing in a store (a so-called minilab). Therefore, most users have to come to the store two times. Accordingly, in the systems of a color negative film and a color paper at present, further sharp speedup of the development processing time is desired to respond to the demand of users of having done with going to the store by one time. 
     The reduction of the development processing time has been conventionally conducted mainly by the shortening of the desilvering step after the color development processing step. Taking the above-described C-41 processing and CN-16FA processing as examples, the color developing time of the former is 3 minutes and 15 seconds, that of the latter is 3 minutes and 5 seconds, and they are much the same with respect to the color developing time. In CN-16FA processing, the color developing time occupies about 40% of the entire development processing time. Therefore, the speedup of the color developing time is essential for further sharp reduction of the development processing time. 
     On the other hand, C-41 processing and the development processing interchangeable therewith (e.g., CN-16FA processing) have prevailed world-widely. For introducing the rapid processing whose color developing time is speeded up into the practical market, this rapid processing is required to have the interchangeability with C-41 processing. 
     A color negative light-sensitive material in general comprises several spectral-sensitive silver halide emulsion layers and is designed so as to have optimal balance of gradation of emulsion layers when development processed, but when rapid processing the color developing time of which is speeded up is carried out, the balance of gradation is upset and the color reproducibility is conspicuously deteriorated. 
     A processing method of obtaining the same gradation when development processing is conducted respectively with different color developing times is disclosed for example, in JP-A-2-2553 (the term &#34;JP-A&#34; as used herein means an &#34;unexamined published Japanese patent application&#34;). According to this method, the same gradation can be obtained by changing the processing temperature, the concentration of the color developing agent in a color developing solution and the color developing time. Specifically, it is disclosed in Example 1 of the above patent application that the same gradation as the gradation (a γ value) which is obtained by the processing temperature of 38° C., the concentration of the color developing agent of 15 mmol/liter, and the color developing time of 3 minutes and 15 seconds (this processing is thought to be equal to C-41 processing) can be obtained by the processing temperature of 38° C., the concentration of the color developing agent of 150 mmol/liter, and the color developing time of 1 minute and 30 seconds. 
     However, since the concentration of the color developing agent according to the above method of shortening the color developing time exceeds 100 mmol/liter, the self-coupling reaction of the color developing agent in the color developing solution is conspicuously accelerated, fluctuations of photographic characteristics after storage due to the reduction of the concentration of the color developing agent are large, and the coloring to the photographic material by the product of the self-coupling reaction increases. Further, the amount of the color developing agent remaining in the photographic material after development processing increases and, in particular, the density in the unexposed portion (stain) of the photographic material markedly rises when stored at room temperature. 
     With a view to avoiding the above problem, the color developing time was shortened to 1 minute and 30 seconds or less with the concentration of the color developing agent being 80 mmol/liter or less and the processing temperature being 40° C. or more, as a result, the diffusion of the color developing agent became rate-determined and the development of the lower layer (the emulsion layer nearer to the support) of the photographic material was delayed than the development of the upper layer (the emulsion layer farther from the support), and the balance of gradation of the upper layer with the lower layer was upset and the color reproducibility was conspicuously deteriorated. 
     A method of introducing a coupler which releases a developing agent upon coupling reaction into a photographic material as disclosed, for example, in JP-A-61-156126 is known as a method of accelerating development during color development processing. However, the balance of gradation could not be improved by the introduction of such a compound because development was accelerated in ordinary processing and rapid processing. 
     SUMMARY OF THE INVENTION 
     Accordingly, an object of the present invention is to provide a silver halide color photographic material which is improved in the upset of the balance of gradation due to shortening of the color developing time, and which is capable of providing images of the same gradation in any development processing now widely prevailing and super-rapid processing in which the color developing time is speeded up, and a further object is to provide a method for forming an image using the same.

     A water-soluble chelating agent is contained from the first in color development processing solutions of C-41 processing and the development processing interchangeable therewith (e.g., CN-16FA processing) for the purpose of masking metal ions. On the basis of this fact, by making use of a chelate exchange reaction in the release of a photographically useful compound, a combination of a metal complex having high reaction selectivity with a chelating agent has been investigated to design the series which is inactive in ordinary processing but reveals the function only in rapid processing. As a result of examination of various compounds, it was found that a compound having a photographically useful compound which is inactivated by the chelation with a metal according to the present invention has particularly high reactivity with a water-soluble nitrogen-containing heterocyclic carboxylic acid chelating agent, thus the reaction control between two kinds of processing has become possible. 
     A compound having a photographically useful compound which is inactivated by the chelation with a metal according to the present invention will be described in detail below.

     Various known methods can be used in the present invention for introducing a compound having a photographically useful compound which is inactivated by the chelation with a metal into a photographic material. It is preferred in the present invention for said compound to be contained as solid particles since the storage stability with the lapse of time of the photographic material of the present invention becomes better. 
     A method of producing solid particle colloid of a photographically useful compound of a sub-micrometer size is disclosed in British Patent 1,570,362 in which a photographically useful compound is made into aqueous slurry with an auxiliary dispersant using mills such as a sand mill and a bead mill and dispersing media (beads and balls), and the dispersing media are removed from the pulverized slurry to obtain solid particle colloid. Alkylphenoxyethoxysulfonic acid, naphthalenesulfonic acid, polyvinyl alcohol and polyvinyl pyrrolidone can be cited as an auxiliary dispersant. 
     The compound according to the present invention is dissolved according to the oil-in-water dispersion method disclosed in U.S. Pat. No. 2,322,027 using high boiling point organic solvents having a boiling point of 175° C. or more at normal pressure, such as phthalic acid esters, phosphoric acid esters, benzoic acid esters, fatty acid esters, amides, phenols, alcohols, carboxylic acids, N,N,N-dialkylanilines, hydrocarbons, oligomers or polymers and/or low boiling point organic solvents having a boiling point of about 30° C. to about 160° C. at normal pressure, such as amides, ethers, etc., then emulsified and dispersed in hydrophilic colloid, such as gelatin. 
     The process and effects of the latex dispersion method and specific examples of latexes for impregnation are disclosed in U.S. Pat. No. 4,199,363, German Patent Application (OLS) Nos. 2,541,274, 2,541,230 and EP-A-294104. These high boiling point organic solvents and latexes can be imparted with not only the function as mere dispersants but also various functions such as the reaction control of the compound according to the present invention, the control of coloring, the improvement of the physical properties of gelatin film, etc., by selecting the structures thereof. The form of high boiling point organic solvents may be any of liquid, wax or solid. 
     A compound having a photographically useful compound which is inactivated by the chelation with a metal according to the present invention is preferably contained in the silver halide emulsion layer nearest to the support or in the layer adjacent thereto, and may be contained in a single layer or may be contained in a plurality of layers. Said compound according to the present invention may be used alone or two or more compounds may be used, further, two or more compounds may be contained in separate layers. 
     Although the compound according to the present invention is preferably contained in the silver halide emulsion layer nearest to the support or in the layer adjacent thereto, it can be contained in any layers in addition to the above-described layer for the purpose of further controlling gradation and improving the storage stability. 
     The addition amount of the compound having the photographically useful compound which is inactivated by chelation with a metal according to the present invention is from 5×10 -6  mol to 2×10 -2  mol, preferably from 1×10 -4  mol to 1×10 -2  mol, and more preferably from 2×10 -4  mol to 5×10 -3  mol, per m 2  of the photographic-material, although it is varied according to the kinds of various photographic organic elements and silver halide emulsion contained in the layer to which the compound is added and the kinds of photographically useful compounds released. 
     The thus-introduced compound according to the present invention is present stably as a metal complex because a chelating agent is not present in high concentration in a photographic material during storage. 
     The behavior of the compound according to the present invention during development processing is described below. When a chelating agent is not contained in a processing solution or is contained in such low concentration as the function thereof is negligible, or when only a chelating agent having weaker affinity to the metal (M) in the compound according to the present invention than that of the ligand (LIG) is contained, the compound according to the present invention is present stably as a metal complex. That is, when the compound according to the present invention is emulsified and dispersed, the complex remains in an oil droplet and protected from various chemical reactions, therefore, the photographically useful compound is a little released. Further, when the compound is solid dispersed, the complex is present as a solid, therefore, the photographically useful compound is little released. 
     When a chelating agent having the equal or more affinity to the metal (M) in the compound according to the present invention than that of the ligand (LIG) is contained in a processing solution, a ligand exchange reaction is caused between the compound according to the present invention and the chelating agent in a processing solution, and because the compound according to the present invention is deprived of the metal, the compound becomes to have high reactivity. The mode of the succeeding reaction varies depending on the structure of the compound, but photographically useful compounds are quickly released through various intermolecular or intramolecular reactions. 
     The method of searching for the gradient in the present invention is explained. 
     First, the test sample of a photographic material is wedgewise exposed to a standard white light source (a light source having energy distribution of 4,800° K of black body radiation), and after the designated development processing is conducted, absorption densities of cyan, magenta and yellow are measured through red, green and blue filters by status M condition to obtain a characteristic curve. Each point of fog +0.25, +0.5, +1.0, +1.5 and +1.75 of the absorption densities of cyan, magenta and yellow to the logarithm of exposure amount (axis of abscissa) is plotted from the characteristic curve obtained, and these points are linearly approximated by the least square method. Tan θ to the angle θ from the axis of abscissa is defined as the gradient γ of the photographic material and the gradients γ of cyan, magenta and yellow are taken as γ (C), γ (M) and γ (Y), respectively. 
     When development processing I and development processing II are carried out, the gradients of yellow, magenta and cyan obtained by these development processing, γ I  (C), γ I  (M), γ I  (Y), and γ II  (C), γ II  (M), γ II  (Y), respectively, of the photographic material of the present invention satisfy the following conditions: 
     0.8≦γ II  (C)/γ I  (C)≦1.2 
     0.8≦γ II  (M)/γ I  (M)≦1.2 
     0.8≦γ II  (Y)/γ I  (Y)≦1.2 
     More preferably they satisfy the following conditions: 
     0.9≦γ II  (C)/γ I  (C)≦1.1 
     0.9≦γ II  (M)/γ I  (M)≦1.1 
     0.9≦γ II  (Y)/γ I  (Y)≦1.1 
     When these conditions are not satisfied, the tint of the color of the print obtained from the color negative film developed by at least either one of development processing I or II breaks and the color reproduction worth appreciating cannot be obtained. 
     In the present invention, γ I  (C), γ I  (M), γ I  (Y), γ II  (C), γ II  (M), γ II  (Y) each is preferably from 0.50 to 0.90, more preferably from 0.60 to 0.85, and particularly preferably from 0.65 to 0.80. 
     The color developing solutions used in development processing I and II for use in the present invention are explained below. Development processing I according to the present invention is processing corresponding to Kodak C-41 which is the processing for color negative films widely used in these days and is designed so that preferred gradation can be obtained, in general, in 3 minutes and 15 seconds. Development processing II is processing the speed of which is more increased than that of development processing I and which is contrived so that the gradation which approximates to the gradation in development processing I in 1 minute of color developing time can be obtained by enhancing the development activity by increasing the concentration of a developing agent and raising the processing temperature. However, when a photographic material beyond the scope of the present invention is processed, as the development of the lowermost red-sensitive layer is delayed, gradations cannot be completely made to coincide with. 
     Development processing I is development processing characterized in that color development processing is carried out in 3 minutes and 15 seconds of the color developing time at the temperature of a color developing solution of 38° C. using a color developing solution containing from 15 to 20 mmol/liter of 2-methyl-4- N-ethyl-N-(β-hydroxyethyl)-amino!aniline as a color developing agent. 
     Development processing II is development processing characterized in that color development processing is carried out in 60 seconds of the color developing time at the temperature of a color developing solution of 45° C., using a color developing solution containing from 35 to 40 mmol/liter of 2-methyl-4- N-ethyl-N-(β-hydroxyethyl)amino!aniline as a color developing agent, and containing at least one water-soluble nitrogen-containing heterocyclic carboxylic acid chelating agent. 
     2,6-Pyridinedicarboxylic acid is preferably used as a water-soluble nitrogen-containing heterocyclic carboxylic acid chelating agent and the addition amount thereof is preferably from 1×10 -2  mol to 1×10 -1  mol and more preferably from 2×10 -2  mol to 6×10 -2  mol. 
     Development processing II is prescribed by adjusting the gradation of the uppermost light-sensitive layer of the photographic material (in general, a blue-sensitive layer) within the above range to coincide with the gradation obtained in development processing I. 
     The pH of the color developing solutions in development processing I and II is 10.05. It is preferred to use a carbonate to maintain the pH of the processing solution 10.05. The addition amount thereof is preferably 0.1 mol/liter or more and from 0.2 to 0.3 mol/liter is particularly preferred. 
     Hydroxylamine and sulfite are preferably used as preservatives for a color developing agent. The addition amount of hydroxylamine is preferably from 0.05 to 0.2 mol/liter. The addition amount of sulfite is preferably from 0.02 to 0.04 mol/liter. 
     A bromine ion can be added to a color developing solution for adjusting developing speed. 
     Further, various chelating agent can be added to a color developing solution. 
     The processing steps after color development of development processing I and II (a desilvering step, a washing step) may be common to development processing I and II, and the processing solutions in development processing A and B described later can be used. 
     Development processing I is a development processing wherein various processing conditions of development processing A are limited, and development processing II is a development processing wherein various processing conditions of development processing B are limited. 
     Specific examples of development processing I and development processing II are described below. When these two processes are conducted, the gradations of the uppermost light-sensitive layer (in general, a blue-sensitive layer) of the photographic material are contrived to almost coincide with.

The temperature and pH of the prebath are the same as in the color developing solution, and the kind and the concentration of the water-soluble nitrogen-containing heterocyclic carboxylic acid chelating agent are the same as in the case to be contained in the color developing solution. 
     As hydroxylamine can be widely used as a preservative of a color developing solution, when higher preservability is required, hydroxylamine derivatives having an alkyl group, a hydroxyalkyl group, a sulfoalkyl group or a carboxyalkyl group as a substituent are preferred. Specifically, N,N-di-(sulfoethyl)hydroxylamine, monomethylhydroxylamine, dimethylhydroxylamine, monoethylhydroxylamine, diethylhydroxylamine, and N,N-di(carboxyethyl)hydroxylamine are preferably used.

The concentration of these bleaching agents is preferably from 0.05 to 0.3 mol per liter of the processing solution having bleaching ability, and for reducing the discharge amount to the environment, the concentration from 0.1 to 0.15 mol per liter is preferred. When the solution having bleaching ability is a bleaching solution, it is preferred to contain bromide in an amount of from 0.2 to 1 mol, and particularly preferably from 0.3 to 0.8 mol, per liter of the bleaching solution. 
     The replenisher of the solution having bleaching ability contains fundamentally the concentration of each component calculated by the following equation. According to this procedure, the concentration in the mother solution can be maintained constant. 
     
         C.sub.R =C.sub.T ×(V.sub.1 +V.sub.2)/V.sub.1 +C.sub.P 
    
     C R  : The concentration of the component in the replenisher 
     C T  : The concentration of the component in the mother solution (processing tank solution) 
     C p  : The concentration of the component consumed during processing 
     V 1  : The replenishing rate of the replenisher having bleaching ability per m of the photographic material (ml) 
     V 2  : The amount of carryover from the prebath by m 2  of the photographic material (ml) 
     In addition, a bleaching solution preferably contains a pH buffer, in particular, comparatively odorless dicarboxylic acids such as succinic acid, maleic acid, malonic acid, glutaric acid, and adipic acid are preferred. It is also preferred to use known bleaching accelerators disclosed in JP-A-53-95630, RD, No. 17129, and U.S. Pat. No. 3,893,858. 
     A bleaching solution is preferably replenished with a bleaching replenisher in an amount of from 50 to 1,000 ml per m 2  of the photographic material, more preferably from 80 to 500 ml and most preferably from 100 to 300 ml. Further, a bleaching solution is preferably conducted aeration. 
     The compounds and the processing conditions disclosed in line 10, left lower column, page 7 to line 19, right lower column, page 8 of JP-A-4-125558 can be applied to the processing solution having fixing ability. 
     In particular, for improving fixing speed and preservability, the compounds represented by formula (I) or (II) disclosed in JP-A-6-301169 are preferably added to the processing solution having fixing ability alone or in combination. Further, the use of the sulfinic acid disclosed in JP-A-1-224762 as well as p-toluenesulfinate is preferred for improving preservability. 
     In the solution having bleaching ability and the solution having fixing ability, ammonium is preferably used as a cation for improving desilvering ability but taking the reduction of the environmental pollution into consideration, ammonium is preferably reduced or, if possible, not contained at all. 
     In bleaching, blixing and fixing processes, it is particularly preferred to carry out the jet stirring as disclosed in JP-A-1-309059. 
     The replenishing rate of the replenisher in blixing process or fixing process is from 100 to 1,000 ml, preferably from 150 to 700 ml, and particularly preferably from 200 to 600 ml, per m of the photographic material. 
     It is preferred to recover silver by installing various silver recovery devices by in-line and off-line systems in blixing and fixing processes. Using an in-line system, processing can be carried out with a reduced concentration of silver in a solution, as a result, the replenishing rate can be reduced. Further, it is preferred to recover silver by an off-line system and reuse the solution after silver recovery as a replenisher. 
     Blixing process and fixing process may comprise a plurality of processing tanks and it is preferred to adopt a multistage countercurrent system with each tank being arranged in cascade piping. From the balance with the size of a processor, in general, two-tank cascade structure is effective and the proportion of the processing time in the preceding tank and the succeeding tank is preferably from 0.5/1 to 1/0.5, particularly preferably from 0.8/1 to 1/0.8. 
     From the viewpoint of improving preservability, it is preferred that a free chelating agent not in the form of a metal complex is contained in a blixing solution or a fixing solution, and the biodegradable chelating agent described above with respect to the bleaching solution is preferably used as such a chelating agent. 
     With respect to washing and stabilizing processes, the contents disclosed in line 6, right lower column, page 12 to line 16, right lower column, page 13 of the above JP-A-4-125558 can be preferably applied to the present invention. In particular, the use of the azolylmethylamines disclosed in EP-A-504609 and EP-A-519190, or the N-methylolazoles disclosed in JP-A-4-362943 in place of formaldehyde in a stabilizing solution, and the elimination of image stabilizers such as formaldehyde from a stabilizing solution, by introducing a 2-equivalent magenta coupler into a photographic material are preferred from the work environmental protection. 
     Further, the stabilizing solution disclosed in JP-A-6-289559 can preferably be used to reduce the adhesion of dusts to a magnetic recording layer coated on a photographic material. 
     The replenishing rate of washing water and a stabilizing solution is preferably from 80 to 1,000 ml, more preferably from 100 to 500 ml, and still more preferably from 150 to 300 ml, per m 2  of the photographic material, which is a preferred range from both sides of the security of washing or stabilizing function and the reduction of waste solution for environmental protection. In processing with such a replenishing rate, it is preferred to use known fungicides such as thiabendazole, 1,2-benzisothiazolin-3-one, and 5-chloro-2-methylisothiazolin-3-one, antibiotics such as gentamycin, and deionized water by ion exchange resin to prevent proliferation of bacteria and fungus. It is more effective to use deionized water with biocides and antibiotics in combination. 
     The solution in a washing or stabilizing tank is preferably treated by reverse osmosis treatment as disclosed in JP-A-3-46652, JP-A-3-53246, JP-A-3-55542, JP-A-3-121448 and JP-A-3-126030 to reduce the replenishing rate, and in this case a reverse osmosis membrane is preferably a low pressure reverse osmosis membrane. 
     In the processing of the present invention, it is particularly preferred to conduct the compensation of evaporation of processing solutions as disclosed in Hatsumei-Kyokai, Kokai-Giho, Kogi No. 94-4992. In particular, according to formula-1 on page 2 of the above literature, the method of compensation based on the information of the temperature and humidity of the atmosphere where the processor is installed is preferred. The water to be used for the compensation of evaporation is preferably drawn from the replenisher tank of water washing, and in such a case deionized water is preferably used as the water washing replenisher. 
     The processing chemicals disclosed in line 15, right column, page 3 to line 32, left column, page 4 of the above Kokai Giho are preferably used in the present invention. The film processor disclosed in lines 22 to 28, right column, page 3 of the above Kokai Giho is preferably used therefor. 
     Preferred processing chemicals, automatic processors, and specific examples of the evaporation compensation method for carrying out the present invention are disclosed in line 11, right column, page 5 to the last line, right column, page 7 of the above Kokai Giho. 
     The processing chemicals for use in the present invention may be supplied in any form such as the solution of the concentration of the working solutions, concentrated solutions, granulated powders, dusting powders, tablets, paste or emulsions. As examples of such processing chemicals, there are solution chemicals contained in a low oxygen permeable container disclosed in JP-A-63-17453, vacuum packaged dusting powders and granulated powders disclosed in JP-A-4-19655 and JP-A-4-230748, granulated powders containing water-soluble polymers disclosed in JP-A-4-221951, tablets disclosed in JP-A-51-61837 and JP-A-6-102628, and paste-like processing chemicals disclosed in JP-A-57-500485, and any of these can be used preferably, but from the convenience at the time of use, it is preferred to use solution chemicals previously prepared in the concentration of the working solutions. 
     As the materials of containers for these processing chemicals, polyethylene, polypropylene, polyvinyl chloride, polyethylene terephthalate, and nylon are used alone or as a composite material. Materials are selected according to the levels of the oxygen permeability required. For a solution which is liable to be oxidized, for example, a color developing solution, materials of low oxygen permeability are preferred, specifically, polyethylene terephthalate and a composite material of polyethylene and nylon. These materials preferably have a thickness of from 500 to 1,500 μm and oxygen permeability of 20 ml/m 2  ·24 hrs·atm or less. 
     The photographic material of the present invention comprises at least one blue-sensitive layer, at least one green-sensitive layer and at least one red-sensitive layer on a support. Unit light-sensitive layers are generally arranged in the order of red-sensitive layer, green-sensitive layer and blue-sensitive layer from the support side. However, the order of arrangement can be reversed depending on the purpose, alternatively, the light-sensitive layers may be arranged in such a way that a layer having a different spectral sensitivity is interposed between layers having the same spectral sensitivity. Light-insensitive layers may be provided between the above-described silver halide light-sensitive layers, and on the uppermost layer and beneath the lowermost layer of the silver halide light-sensitive layers. These light-insensitive layers may contain couplers, DIR compounds and color mixing preventives described below. As the plurality of silver halide emulsion layers constituting each unit light-sensitive layer, a two-layer structure of a high sensitivity emulsion layer and a low sensitivity emulsion layer can be preferably used with the emulsion layers being arranged so as to decrease in sensitivity toward a support in turn as disclosed in German Patent 1,121,470 and British Patent 923,045. In addition, a low sensitivity emulsion layer may be provided farther from the support and a -thigh sensitivity emulsion layer may be provided nearer to the support as disclosed in JP-A-57-112751, JP-A-62-200350, JP-A-62-206541 and JP-A-62-206543. 
     In one specific example, a low sensitivity blue-sensitive layer (BL)/a high sensitivity blue-sensitive layer (BH)/a high sensitivity green-sensitive layer (GH)/a low sensitivity green-sensitive layer (GL)/a high sensitivity red-sensitive layer (RH)/a low sensitivity red-sensitive layer (RL), or BH/BL/GL/GH/RH/RL, or BH/BL/GH/GL/RL/RH can be arranged in this order from the side farthest from the support. 
     A blue-sensitive layer/GH/RH/GL/RL can be arranged in this order from the side farthest from the support as disclosed in JP-B-55-34932. Further, a blue-sensitive layer/GL/RL/GH/RH can be arranged in this order from the side farthest from the support as disclosed in JP-A-56-25738 and JP-A-62-63936. 
     Further, useful arrangements include the arrangement in which there are three layers having different degrees of sensitivities with the sensitivity being lower towards the support such that the upper layer is a silver halide emulsion layer having the highest sensitivity, the middle layer is a silver halide emulsion layer having a lower sensitivity than that of the upper layer, and the lower layer is a silver halide emulsion layer having a lower sensitivity than that of the middle layer, as disclosed in JP-B-49-15495. In the case of the structure of this type comprising three layers having different degrees of sensitivity, the layers in the unit layer of the same spectral sensitivity may be arranged in the order of a middle sensitivity emulsion layer/a high sensitivity emulsion layer/a low sensitivity emulsion layer, from the side farthest from the support, as disclosed in JP-A-59-202464. 
     Alternatively, the layers can be arranged in the order of a high sensitivity emulsion layer/a low sensitivity emulsion layer/a middle sensitivity emulsion layer, or a low sensitivity emulsion layer/a middle sensitivity emulsion layer/a high sensitivity emulsion layer. Moreover, the arrangement may be varied as indicated above in the case where there are four or more layers. 
     For improving color reproducibility, a donor layer. (CL) for an interlayer effect having a different spectral sensitivity distribution from a main light-sensitive layer such as BL, GL and RL may preferably be provided adjacent or close to the main light-sensitive layer, as disclosed in U.S. Pat. Nos. 4,663,271, 4,705,744, 4,707,436, JP-A-62-160448 and JP-A-63-89850. 
     The silver halides preferably used in the present invention are silver iodobromide, silver iodochloride or silver iodochlorobromide containing about 30 mol % or less of silver iodide, and particularly preferably used are silver iodobromide or silver iodochlorobromide containing from about 2 mol% to about 10 mol % of silver iodide. 
     Silver halide grains in a photographic emulsion may have a regular crystal form such as a cubic, octahedral or tetradecahedral form, an irregular crystal form such as a spherical or plate-like form, a form which has crystal defects such as twin crystal planes, or a form which is a composite of these forms. 
     The silver halide grains may be a fine grain having a grain size of about 0.2 μm or less, or large size grains having a projected area diameter of up to about 10 μm, and the emulsion may be a polydisperse emulsion or a monodisperse emulsion. 
     The term &#34;equivalent-circle diameter&#34; as used hereinafter means a diameter of a circle having the same area as the projected area of a grain. The term &#34;equivalent-sphere diameter&#34; as used hereinafter means a diameter of a sphere having the same volume as the volume of a grain. 
     The silver halide photographic emulsions for use in the present invention can be prepared using the methods disclosed, for example, in Research Disclosure (hereinafter abbreviated to RD), No. 17643 (December, 1978), pages 22 and 23, &#34;I. Emulsion Preparation and Types&#34;, RD, No. 18716 (November, 1979), page 648, RD, No. 307105 (November, 1989), pages 863 to 865, P. Glafkides, Chimie et Physique Photographique, Paul Montel (1967), G. F. Duffin, Photographic Emulsion Chemistry, Focal Press (1966), and V. L. Zelikman et al., Making and Coating Photographic Emulsion, Focal Press (1964). 
     The monodisperse emulsions disclosed in U.S. Pat. Nos. 3,574,628, 3,655,394 and British Patent 1,413,748 are also preferred. 
     Further, tabular grains having an aspect ratio of about 3 or more can also be used in the present invention. Tabular grains can be easily prepared according to the methods disclosed, for example, in Gutoff, Photographic Science and Engineering, Vol. 14, pages 248 to 257 (1970), U.S. Pat. Nos. 4,434,226, 4,414,310, 4,433,048, 4,439,520 and British Patent 2,112,157. 
     The crystal structure may be uniform, or the interior and exterior parts of the grains may be comprised of different halogen compositions, or the grains may have a layered structure. Silver halides which have different compositions may be joined with an epitaxial junction or may be joined with compounds other than a silver halide, such as silver thiocyanate or lead oxide. Further, mixtures of grains which have various crystal forms may also be used. 
     The above described emulsions may be of the superficial latent image type wherein the latent image is primarily formed on the surface, or of the internal latent image type wherein the latent image is formed within the grains, or of a type wherein the latent image is formed both at the surface and within the grains, but a negative type emulsion is essential. Of the internal latent image types, the emulsion may be a core/shell type internal latent image type emulsion as disclosed in JP-A-63-264740, and a method for preparation of such a core/shell type internal latent image type emulsion is disclosed in JP-A-59-133542. The thickness of the shell of this emulsion varies depending on the development process, but is preferably from 3 to 40 nm, and particularly preferably from 5 to 20 nm. 
     The silver halide emulsion for use in the present invention is usually subjected to physical ripening, chemical ripening and spectral sensitization. Additives for use in such processes are disclosed in RD, No. 17643, RD, No. 18716, and RD, No. 307105, and the locations of these disclosures are summarized in a table below. 
     In the photographic material of the present invention, two or more different types of emulsions which are different in terms of at least one of the characteristics of grain size, grain size distribution, halogen composition, the form of the grains, or light sensitivity of the light-sensitive silver halide emulsion can be used in admixture in the same layer. 
     It is preferred to use the silver halide grains having a fogged grain surface as disclosed in U.S. Pat. No. 4,082,553, the silver halide grains having a fogged grain interior as disclosed in U.S. Pat. No. 4,626,498 and JP-A-59-214852, or colloidal silver in light-sensitive silver halide emulsion layers and/or substantially light-insensitive hydrophilic colloid layers. Silver halide grains having a fogged grain interior or surface are silver halide grains which can be developed uniformly (not imagewise) irrespective of whether these grains are in an unexposed part or an exposed part of the photographic material, and methods for the preparation thereof are disclosed in U.S. Pat. No. 4,626,498 and JP-A-59-214852. The silver halide which forms the internal nuclei of a core/shell type silver halide grains having a fogged grain interior may have different halogen compositions. The silver halide having a fogged grain interior or surface may be any of silver chloride, silver chlorobromide, silver iodobromide, or silver chloroiodobromide. The average grain size of these fogged silver halide grains is preferably from 0.01 to 0.75 4μm, and particularly preferably from 0.05 to 0.6 μm. Further, the form of the grains may be regular grains and may be a polydisperse emulsion, but a monodisperse emulsion (at least 95% of which have a grain size within ±40% of the average grain size in terms of the weight or number of silver halide grains) is preferred. 
     The use of light-insensitive fine grained silver halides is preferred in the present invention. Light-insensitive fine grained silver halides are fine grained silver halides which are not sensitive to light upon imagewise exposure for obtaining color images and which do not substantially undergo development during development processing, and they are preferably not pre-fogged. The fine grained silver halide has a silver bromide content of from 0 to 100 mol %, and may contain silver chloride and/or silver iodide, if necessary. The fine grained silver halides which have a silver iodide content of from 0.5 to 10 mol% are preferred. The average grain size of the fine grained silver halide (the average value of the diameters of the circles equivalent to the projected areas) is preferably from 0.01 to 0.5 μm, more preferably from 0.02 to 0.2 μm. 
     The fine grained silver halide can be prepared by the same methods as the preparation of generally used light-sensitive silver halides. In the preparation of the fine grained silver halide, the surface of the silver halide grains does not need to be optically sensitized and also does not need to be spectrally sensitized. However, it is preferred to previously include known stabilizers such as triazole based, azaindene based, benzothiazolium based, or mercapto based compounds, or zinc compounds in the fine grained silver halide before addition to the coating solution. Colloidal silver can be included in the layer containing the fine grained silver halide grains. 
     The coating weight of silver in the photographic material of the present invention is preferably 6.0 g/m 2  or less, and most preferably 4.5 g/m 2  or less.

Measurement at this time is conducted using a stainless steel ball having a diameter of 5 mm at a transporting speed of 60 cm/min (25° C., 60% RH). In this evaluation, when the opposite material is replaced with the light-sensitive layer surface, almost the same level of value can be obtained. 
     Examples of the sliding agent which can be used in the present invention include polyorganosiloxane, a higher fatty acid amide, a higher fatty acid metal salt, and an ester of a higher fatty acid and a higher alcohol.

     Zero point two (0.2) gram/m of a dispersion of fine particle powder of a stannic oxide-antimony oxide composite having the average particle size of 0.005 μm and specific resistance of 5 Ω·cm (the particle size of the second agglomerate: about 0.08 μm), 0.05 g/m 2  of gelatin, 0.02 g/m 2  of (CH 2  ═CHSO 2  CH 2  CH 2  NHCO) 2  CH 2 , 0.005 g/m 2  of polyoxyethylene-p-nonylphenol (polymerization degree: 10) and 0.22 g/m 2  of resorcin were coated. 
     3-2) Coating of magnetic recording layer 
     Zero point zero six (0.06) gram/m 2  of cobalt-γ-iron oxide which was coating-treated with 3-polyoxyethylene-propyloxytrimethoxysilane (polymerization degree: 15) (15 wt %) (specific surface area: 43 m 2  /g, major axis: 0.14 μm, minor axis: 0.03 μm, saturation magnetization: 89 emu/g, Fe +2  /Fe +3  is 6/94, the surface was treated with 2 wt %, respectively, based on the iron oxide, of aluminum oxide and silicon oxide), 1.2 g/m 2  of diacetyl cellulose (dispersion of the iron oxide was carried out using an open kneader and a sand mill) and 0.3 g/m 2  of C 2  H 5  C CH 2  OCONH--C 6  H 3  (CH 3 )NCO! 3  as a curing agent, with acetone, methyl ethyl ketone and cyclohexanone as solvents, were coated with a bar coater to obtain a magnetic recording layer having the film thickness of 1.2 μm. Ten (10) mg/m 2  of silica particles (0.3 μm) as a matting agent and 10 mg/m 2  of an aluminum oxide abrasive (0.15 μm) coating-treated-with 3-polyoxyethylene-propyloxytrimethoxysilane (polymerization degree: 15) (15 wt %) were added. Drying was conducted at 115° C. for 6 minutes (the temperature of the roller and transporting device of the drying zone was 115° C.). The increase of the color density of D of the magnetic recording layer by X-light (a blue filter) was about 0.1, and saturation magnetization moment of the magnetic recording layer was 4.2 emu/g, coercive force was 7.3×10 4  A/m, and rectangular ratio was 65%. 
     3-3) Preparation of sliding layer 
     A mixture of diacetyl cellulose (25 mg/m 2 ), C 6  H 13  CH(OH)C 10  H 20  COOC 40  H 81  (Compound a, 6 mg/m 2 ) and C 50  H 101  O(CH 2  CH 2  O) 16  H (Compound b, 9 mg/m 2 ) was coated. This mixture was melted in xylene/propylene glycol monomethyl ether (1/1 by volume) by heating at 105° C., and the solution was poured into propylene glycol monomethyl ether (10 time amount) at room temperature and dispersed, and the dispersion was further dispersed in acetone (average particle size: 0.01 μm) and then added to the coating solution. Fifteen (15) mg/m 2  of silica particles (0.3 μm) as a matting agent and 15 mg/M 2  of an aluminum oxide abrasive (0.15 μm) coating-treated with 3-polyoxyethylene-propyloxytrimethoxysilane (polymerization degree: 15) (15 wt %) were added. Drying was conducted at 115° C. for 6 minutes (the temperature of the roller and transporting device of the drying zone was 115° C.). The thus-obtained sliding layer showed excellent characteristics of dynamic friction coefficient of 0.06 (a stainless steel hard ball of 5 mmφ, load: 100g., speed: 6 cm/min), static friction coefficient of 0.07 (a clip method), and dynamic friction coefficient of 0.12 between the surface of the emulsion described below and the sliding layer. 
     4) Coating of light-sensitive layer 
     Next, each layer having the following composition was multilayer coated on the opposite side of the above obtained backing layer and a color negative film was prepared as Sample No. 101. 
     Composition of Light-Sensitive Layer 
     The main components for use in each layer are classified as follows: 
     ExC: Cyan Coupler 
     ExM: Magenta Coupler 
     ExY: Yellow Coupler 
     ExS: Sensitizing Dye 
     UV: Ultraviolet Absorber 
     HBS: High Boiling Point Organic Solvent 
     H: Hardening Agent for Gelatin 
     The numeral corresponding to each component indicates the coated weight in unit of g/m 2 , and the coated weight of silver halide is shown as the calculated weight of silver. Further, in the case of a sensitizing dye, the coated weight is indicated in unit of mol per mol of silver halide in the same layer.

 In Table 1:                                                              
 (1) Emulsions J to M were reduction sensitized during preparation of the 
 grains using thiourea dioxide and thiosulfonic acid according to the     
 examples of JPA-2-191938 (corresponding to U.S. Pat. No. 5,061,614).     
 (2) Emulsions C to I, and M were gold, sulfur, and selenium sensitized,  
 respectively, in the presence of the spectral sensitizing dyes which are 
 described at each lightsensitive layer and sodium thiocyanate according t
 the examples of JPA-3-237450 (corresponding to EPA-443453).              
 (3) Low molecular weight gelatin was used in the preparation of the      
 tabular grains according to the examples of JPA-1-158426.                
 (4) In tabular grains, there were observed such dislocation lines as     
 disclosed in JPA-3-237450 (corresponding to EPA-443453), using a high    
 pressure electron microscope.                                            
 (5) Emulsions A to E, G, H, and J to M contained optimal amounts of Rh, I
 and Fe.                                                                  
 
    
     Further, tabularity is defined by Dc/t 2 , taking the average equivalent-circle diameter in the projected area of tabular grains as Dc and the average thickness of tabular grains as t. 
     Preparation of Dispersion of Organic Solid Dispersion Dye 
     ExF-2 shown below was dispersed according to the following method. That is, 21.7 ml of water, 3 ml of a 5% aqueous solution of sodium p-octylphenoxyethoxyethoxyethanesulfonate, and 0.5 g of a 5% aqueous solution of p-octylphenoxypolyoxyethylene ether (polymerization degree: 10) were put in a pot mill having a capacity of 700 ml, and 5.0 g of Dye ExF-2 and 500 ml of zirconium oxide beads (diameter: 1 mm) were added thereto and the content was dispersed for 2 hours. The dispersion was performed using a BO-type vibrating ball mill manufactured by Chuo Koki K.K. The content was taken out after dispersion and added to 8 g of a 12.5% aqueous solution of gelatin and the beads were removed by filtration and the gelatin dispersion of the dye was obtained. The average particle size of fine particles of the dye was 0.44 μm. 
     Solid dispersions of ExF-3, ExF-4 and ExF-6 were obtained in the same manner. The average particle sizes of fine particles of the dyes were 0.24 μm, 0.45 μm and 0.52 μm, respectively. ExF-5 was dispersed according to the micro-precipitation dispersion method disclosed in Working Example 1 of EP-A-549489. The average particle size was 0.06 μm. ##STR20## 
     Sample Nos. 102 to 109 were prepared in the same manner as the preparation of Sample No. 101 except that metal complexes of photographically useful compounds according to the present invention as shown in Table 2 were added to the fourth and fifth layers of Sample No. 101 in the amount of 0.35 mmol, respectively, per m 2  of the photographic material. Metal complexes of photographically useful compounds (2), (41), (57) and (94) were added to samples as solid dispersions and (5), (12), (31) and (75) as emulsified dispersions. 
     Preparation of solid dispersions of metal complexes of photographically useful compounds (2), (41), (57) and (94) according to the present invention, which were added to samples as solid dispersions, was carried out according to the following procedure. Five (5) mmol of the compound to be dispersed, Demole SNB (produced by Kao Corporation) in a 1/2 weight of the compound, 20 ml of water and 100 g of zirconia beads (diameter: 0.5 mm) were added to a vessel having a capacity of 1/8 gallon, and dispersed using a sand grinder TSG-1/8-4U (a product of AIMEX) at 1,500 rpm for 2 hours. After dispersion, beads were filtered off to obtain dispersion solution. 
     The average particle sizes of fine particles of metal complexes of photographically useful compounds (2), (41), (57) and (94) in the dispersion solution were 0.42 μm, 0.49 μm, 0.38 μm and 0.50 μm, respectively. The content of each compound in the dispersion solution was obtained by determination by an atomic absorption analysis of the metal ion in homogeneous solution obtained by a wet ashing method. 
     Metal complexes of photographically useful compounds (5), (12), (31) and (75) were emulsion dispersed with oil-soluble substances contained in each layer. 
     Each sample was prepared two and two and wedgewise exposed to a light source having energy distribution of 4,800° K of black body radiation, then development processing I-1 and development processing II-1 described above were conducted. 
     Absorption densities of cyan, magenta and yellow were measured by status M condition to obtain a characteristic curve. From the characteristic curve obtained, the gradient of each of cyan, magenta and yellow was searched for by the method described above. The ratios of the gradients in processing II-1 to the gradients in processing I-1 are shown in Table 2.

     Washing Water 
     City water was passed through a mixed bed column packed with an H-type strongly acidic cation exchange resin (Amberlite IR-120B of Rohm &amp; Haas) and an OH-type anion exchange resin (Amberlite IR-400 of Rohm &amp; Haas) and treated so as to reduce the calcium ion and magnesium ion concentrations to 3 mg/liter or less, subsequently 20 mg/liter of sodium isocyanurate dichloride and 0.15 g/liter of sodium sulfate were added thereto. The pH of this washing water was in the range of from 6.5 to 7.5.

     As is apparent from the results in Table 3, when color photographic materials of the present invention were subjected to development processing B-1 to B-3, which were rapid processing, the same gradient as subjected to development processing A-1, which was general processing could be provided, and good images could be obtained. On the other hand, it is seen that when development processing B-4 which used a color developing solution not containing a water-soluble nitrogen-containing heterocyclic carboxylic acid chelating agent was conducted, color photographic materials of the present invention did not provide preferred gradient. 
     EXAMPLE 3 
     Sample Nos. 110 and 111 were prepared in the same manner as the preparation of Sample No. 101 except that metal complexes of the compounds having photographically useful compounds according to the present invention (43) and (64) were added to the fourth and fifth layers of Sample No. 101 in an amount of 0.35 mmol per m 2  of the material, respectively, and the amount of ExC-1 added to the fourth and fifth layers was reduced to one half. Sample No. 112 was prepared by similarly adding the developing agent releasing coupler DRC-1 disclosed in JP-B-61-156126. These samples were subjected to the same development processing in Example 1 and the ratios of the gradients were searched for. The results obtained are shown in Table 4 below.

     As is apparent from the results in Table 4, the obtained to be solved by the present invention cannot be attained only by releasing a development accelerator in a processing solution, but the reaction control is important, which becomes feasible by a photographically useful compound having a metal chelate moiety. 
     EXAMPLE 4 
     Samples as shown in Table 5 were prepared and the same development processing as in Example 1 were carried out and the ratios of the gradients were searched for. Every sample provided almost the same gradient in both rapid processing and general processing and images having excellent color reproducibility could be obtained.

     EXAMPLE 5 
     Sample No. 101 were wedgewise exposed to white light through a filter made by combining a red filter, a green filter and a blue filter each having different optical densities. The exposed samples were subjected to development processing I-1 and samples having different gradations of yellow, magenta and cyan densities were prepared. Then, a standard sample subjected to appropriate gray exposure by white light and an ND filter and processed by development processing I-1 was prepared. Using these samples, the ratios of gradients of yellow, magenta and cyan densities in case of combining filters to gradients of a standard sample were obtained. 
     Based on this exposure conditions, Macbeth color checker was photographed and printed using Sample No. 101 and functional evaluation was conducted with respect to color reproducibility of the printed sample. As a result, if the ratios of the gradients of all of yellow, magenta and cyan to gradients of the standard sample gray exposed are from 0.8 to 1.2, satisfactory images can be obtained by the compensation at printing or as it is. That is, gray not different from the printed image which was obtained using a standard sample could be reproduced. 
     On the other hand, when gradient ratio of at least one of yellow, magenta and cyan is smaller than 0.8 or larger than 1.2, color balance is upset and other colors were seen overlapped with gray. When the gradient ratios of three of yellow, magenta and cyan are all smaller than 0.8 or larger than 1.2, compared with a standard sample, difference of light and shade of gray was large. Thus, samples not satisfying the gradient ratio cannot produce images not differing from a standard sample. 
     A silver halide color photographic material and a method of forming images according to the present invention can provide images having excellent color reproducibility. 
     The present invention can provide a silver halide color photographic material which is improved in the upset of the balance of gradation due to shortening of the color developing time, and which is capable of providing images of the same gradation in any development processing now widely prevailing and super-rapid processing in which the color developing time is speeded up, and a method for forming an image. 
     While the invention has been described in detail and with reference to specific examples thereof, it will be apparent to one skilled in the art that various changes and modifications can be made therein without departing from the spirit and scope thereof.
