The silver halide color photographic light-sensitive material has an excellent color forming property to provide a color image of high maximum color density and good color reproducibility.

Description: FIELD OF THE INVENTION The present invention relates to a silver halide color photographic light-sensitive material excellent in color reproducibility. More particularly, the present invention relates to a silver halide color photographic light-sensitive material containing both a pyrrolotriazole coupler and a non-color forming colorless cyclic imide having a diffusion-resistant group. BACKGROUND OF THE INVENTION When a silver halide color photographic light-sensitive material is exposed and subjected to color development, a coupler is reacted with an oxidation product of an aromatic primary amine developing agent to form a color image. In such a photographic system, color reproduction is performed by a subtractive color process and in order to reproduce blue, green and red colors, yellow, magenta and cyan color images which are in a complementary relation, respectively, are formed. Among them, in order to form a cyan color image, a phenolic or naphtholic coupler is generally employed. However, a dye formed from such a coupler has an undesirable absorption in a green light region. Thus, the coupler causes a serious problem in that color reproducibility of the photographic material is remarkably deteriorated and it has been desired to solve such a problem. In order to solve the problem, heterocyclic compounds are proposed to use as couplers as described, for example, in U.S. Patents 4,728,598 and 4,873,183 and European Patent 249453A2. However, these couplers have another serious problem in that the coupling activity thereof is poor. Pyrroloazoles are proposed in European Patent 491197A1 to solve these problems. Although these compounds are superior to conventional couplers in view of the coupling activity and hue, further improvement has been desired. On the other hand, methods of using additives to solve the above-described problems have been investigated in addition to the studies on structures of couplers per se. For instance, there are a technique for controlling hue by adding amide compounds or phenols as described in U.S. Patent 5,474,880, a technique for increasing color forming property by adding hydrogen-providing compounds having a hydrogen bond as described in JP-A-7-270990 (the term "JP-A" as used herein means an "unexamined published Japanese patent application"), and techniques for improving color reproducibility and color forming property by adding ureas and specific carboxylic acids as described in JP-A-6-258802 and JP-A-6-3782, respectively. However, the above-described problems have not yet been solved sufficiently according to these techniques. Therefore, investigations on the structure of pyrroloazole coupler, the incorporation of additive and a suitable combination thereof have still been made. EP O 894 786 A, which is a prior art document in the sense of Art. 54(3) EPC, discloses a silver halide color photographic material showing improved fastness of dye images, color reproduction, cyan stain, processing cyan color contamination and the like. This document teaches the simultaneous use of a phenidone compound and a pyrrolotriazole cyan coupler. JP 2043540 A relates to a silver halide color photographic material containing a hydroxyphenyl carboxamide cyan coupler. US 2,322,027 discloses a method for the preparation of a color photographic material which comprises the mixing a color-forming compound capable of reacting with a primary aromatic amino coupling developing agent on photographic development, with a substantially water-insoluble, low molecular weight, organic crystalloidal material being so chosen that particles thereof are liquid under conditions of coating and processing. Particularly, a further technical development is necessary to sufficiently enjoy the characteristic of excellent hue of dyes formed from these couplers in photographic light-sensitive materials. SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a silver halide color photographic light-sensitive material having improved color reproducibility and color forming property. Another object of the present invention is to provide a silver halide color photographic light-sensitive material having improved fastness and prevented from the formation of stain and fog. Other objects of the present invention will become apparent from the following description and examples. The present inventors have analyzed in greater detail the mechanism of color-forming reaction of a pyrrolotriazole coupler in a silver halide color photographic light-sensitive material in order to solve the above-described problems. As a result, it has been found that the degradation of color reproducibility and color forming property is caused by the formation of undesirable colored substance during the color-forming reaction process. For the purpose of inhibiting the formation of colored substance, the inventors have made various investigations on structure of pyrrolotriazole couplers and additives which are employed together with the couplers and completed the present invention. The above-described objects of the present invention are accomplished by a silver halide color photographic light-sensitive material comprising a support having provided thereon at least one hydrophilic colloid layer, wherein the silver halide color photographic light-sensitive material contains a coupler represented by the formula (1) shown below and a non-color forming colorless cyclic imide compound having a diffusion-resistant group: wherein R 1 and R 2 each represents an alkyl group or an aryl group; R 3 , R 4 and R 5 each represents a hydrogen atom, an alkyl group or an aryl group; Z represents a non-metallic atomic group necessary to form a saturated ring; R 6 represents a substituent; X represents a heterocyclic group, a substituted amino group or an aryl group; and Y represents a hydrogen atom or a group capable of being released upon color development. with the proviso that when the coupler represented by formula (1) is any of the following couplers: a layer containing the coupler does not simultaneously contain the following nine compounds The coupler represented by formula (1) and the non-color forming colorless cyclic imide compound having a diffusion-resistant group may be present in different hydrophilic colloid layers of the photographic material, but they may as well be present in the same layer.

The bactericides and anti-mold agents described in JP-A-63-271247 are suitably used in the present invention. Gelatin is preferably employed as a hydrophilic colloid in a photographic layer constituting the photographic light-sensitive material according to the present invention. An amount of heavy metal, for example, iron, copper, zinc or manganese, which is included as an impurity in gelatin, is preferably not more than 5 ppm, more preferably not more than 3 ppm. The silver halide photographic light-sensitive material according to the present invention is suitable for a scanning exposure system using a cathode ray tube (CRT) in addition to a conventional printing system using a negative printer. An exposure device using a cathode ray tube is simple, compact and low-cost in comparison with an exposure device using a laser beam. Also, the former is advantageous in view of easy control of an optical axis and color. In the cathode ray tube used for the image exposure, various light emitting materials which emit light in the visible spectra are employed depending on the demand. For instance, a red light emitting material, a green light emitting material and a blue light emitting material are used individually or in a combination of two or more thereof. The light emitting materials are not limited to those of red, green and blue described above, and other light emitting materials which emit yellow light, orange light, purple light or infrared light may also be utilized. Particularly, a cathode ray tube using a combination of these light emitting materials to emit white light is frequently employed. When the photographic light-sensitive material having a plural of light-sensitive layers each having a different spectral sensitivity and the cathode ray tube having a plural of light emitting materials each emitting light having a different spectrum are used, a plural of color image signals are input to the cathode ray tube to emit the respective light and a plural of colors are exposed at once. Alternatively, a successive exposure method wherein each color light is emitted according to the input of the corresponding image signal, in order, and filters which cut color light other than the desired color light are used can be adopted. In general, the successive exposure method is preferred to obtain high quality images, since a cathode ray tube of high resolving power can be used. The photographic light-sensitive material of the present invention can preferably be used in digital scanning exposure system using monochromatic high density light, such as a gal laser, a light emitting diode, a semiconductor laser, a second harmonic generation light source (SHG) comprising a combination of nonlinear optical crystal with a semiconductor laser or a solid state laser using a semiconductor laser as an excitation light source. For obtaining a compact and inexpensive system, it is preferred to use a semiconductor laser, or a second harmonic generation light source (SHG) comprising a combination of nonlinear optical crystal with a semiconductor laser or a solid state laser. In particular, for designing a compact and inexpensive apparatus having a longer duration of life and high stability, it is preferred to use a semiconductor laser, and at least one of exposure light sources should be a semiconductor laser. When such a scanning exposure light source is used, the spectral sensitivity maximum of the photographic light-sensitive material of the present invention can be appropriately set according to the wavelength of the scanning exposure light source to be used. As an oscillation wavelength of a laser can be made half using an SHG light source comprising a combination of non-linear optical crystal with a solid state laser using a semiconductor laser as an excitation light source or a semiconductor laser, blue light and green light can be obtained. Accordingly, it is possible to have the spectral sensitivity maximum of the photographic light-sensitive material in normal three regions of blue, green and red. The exposure time in the scanning exposure is defined as the time necessary to expose the pixel size with the pixel density being 400 dpi, and preferred exposure time is 10 -4 second or less and more preferably 10 -6 second or less. Preferred scanning exposure systems suitable for use in the present invention are described in detail in the patents set forth in the table shown above. In order to process the silver halide photographic light-sensitive material of the present invention, processing elements and processing methods described in JP-A-2-207250, page 26, right lower column, line 1 to page 34, right upper column, line 9 and JP-A-4-97355, page 5, left upper column, line 17 to page 18, right lower column, line 20 are preferably employed. As preservatives in developing solution, the compounds described in the patent set forth in the table shown above are preferably employed. In order to conduct development processing of the photographic light-sensitive material according to the present invention after imagewise exposure, a wet type developing process, for example, a developing method using a conventional developing solution containing an alkaline agent and a developing agent, and an activator method in which a photographic light-sensitive material containing a developing agent is developed with an activator solution such as an alkaline solution containing no developing agent, as well as a dry type developing process without using a processing solution, for example, a heat developing method can be employed. Particularly, the activator method is preferred since the processing solution does not contain a developing agent, thus the control and handling of the processing solution are easy. Also, it is favorable in view of the environmental conservation since a load for treatment of the waste solution is small. The developing agents and precursors thereof which can be incorporated into the photographic light-sensitive material used in the activator method are preferably hydrazine series compounds described, for example, in Japanese Patent Application Nos. 7-63572, 7-334190, 7-334192, 7-334197 and 7-344396. Further, a developing method wherein the photographic light-sensitive material having a reduced coating amount of silver is subjected to an image amplification process (intensification process) using hydrogen peroxide is preferably employed. In particular, it is preferred to apply this method to the activator method. Specifically, an image forming method using the activator solution containing hydrogen peroxide as described in Japanese Patent Application Nos. 7-63587 and 7-334202 is preferably employed. According to the activator method, the photographic material is ordinarily subjected to a desilvering treatment after the treatment with the activator solution. However, in the image amplification process using the photographic material having a reduced coating among of silver, the desilvering treatment is omitted and a simple treatment such as washing with water or stabilizing treatment is conduced. Further, in a system wherein an image information is read from a photographic material by a scanner, the processing method omitting the desilvering treatment can be adopted, even when a photographic light-sensitive material having a large coating amount of silver such as a photographic light-sensitive martial for photographing is processed. Processing elements and processing methods for the activator treatment, desilvering (bleaching/fixing), water washing and stabilizing used in the present invention include those known in the art. Preferably, those described in Research Disclosure, September 1994, Item 36544, pages 536 to 541 and Japanese Patent Application No. 7-63572 are employed. The silver halide color photographic light-sensitive material according to the present invention has an excellent color forming property to provide a color image of high maximum color density and good color reproducibility. The present invention will be explained in grater detail with reference to the following examples, but the present invention should not be construed as being limited thereto. EXAMPLE 1 Preparation of Sample 101 On a cellulose triacetate film support, were provided photographic constituent layers shown below to prepare Sample 101. A coating solution for first layer was prepared in the following manner. Preparation of Coating Solution for First Layer 1.0 g of Cyan Coupler (1) according to the present invention, 2.0 g of Cyclic Imide Compound (A-1) according to the present invention and 2.0 g of tris(isopropylphenyl) phosphate were added to 10.0 ml of ethyl acetate to completely dissolve. The ethyl acetate solution of coupler was added to 42 g of a 10% aqueous gelatin solution containing 5 g/liter of sodium dodecylbenzenesulfonate and the mixture was emulsified and dispersed by a homogenizer. To the emulsified dispersion was added distilled water to make the total amount of 100 g. 100 g of the resulting emulsified dispersion was mixed with a red-sensitive silver halide emulsion having a high silver chloride content (silver bromide content: 0.6 mol%, and containing the red-sensitive Sensitizing Dye G shown below in an amount of 1.1×10 -4 mol per mol of silver halide), and the mixture was dissolved to prepare a coating solution for the first layer having the composition described below. As a gelatin hardening agent, 1-oxy-3,5-dichloro-s-triazine sodium salt was used. Sensitizing Dye G Layer Construction The composition of each layer is described below.

Also, in samples 111 and 112, the amounts of the silver halide emulsion and the cyan coupler were changed to two times of those in Sample 101, respectively. Samples 101 to 115 thus-prepared were evaluated their properties in the following manner. Evaluation 1: Color Forming Property Each sample was stored under the condition of 25°C and 55% RH for 7 days, exposed to red light using a sensitometer (FWH Model, color temperature of a light source: 3200°K, manufactured by Fuji Photo Film Co., Ltd.) through a continuous wedge for sensitometry evaluation, and subjected to development processing according to the processing steps shown below. Then, each sample was subjected to density measurement through a red filter to prepare a sensitometry curve. From the sensitometry curve, the maximum color density (D max ) was determined. The greater the D max , the better the color forming property. Evaluation 2: Color Reproducibility With each sample subjected to the development processing, an absorption spectrum was measured by a spectrophotometer (UV 365 manufactured by Shimadzu Corporation). From the absorption spectrum, absorbance at 500 nm (D 500 nm ) was determined when the absorbance at the maximum absorption wavelength was 1.0. The smaller the D 500 nm , the less is the absorption in a wavelength region which deteriorates cyan color reproduction, and the color reproducibility is improved.

It is also apparent that the above described effect is more remarkable when the carboxylic acid compound coexists with the cyclic imide compound according to the present invention.
