The light-sensitive material comprises a transparent support having on one side thereof a cyan dye-forming coupler-containing red-sensitive silver halide emulsion layer, a magenta dye-forming coupler-containing green-sensitive silver halide emulsion layer, a yellow dye-forming coupler-containing blue-sensitive silver halide emulsion layer, a non-light-sensitive hydrophilic colloid layer and an invisible light-sensitive silver halide emulsion layer containing a dye forming coupler, a colored coupler or a DIR compound.

Description: FIELD OF THE INVENTION The present invention relates to a silver halide color photographic light-sensitive material improved in color reproducibility, particularly relates to a silver halide color photographic light-sensitive material which is excellent in distinguishing the lightness of red color, reproducibility of green color of vegetation, or a description ability of blue sky and a distant view, and the reproducibility of hue of skin color of the light-sensitive material is stabilized with respect to a lightness variation of skin color. Since Kodachrom has been put on the market by Eastman Kodak in 1935, improvement in color photography has continued, and the characteristics of color photography are raised continuously. The improvement of color photography includes minifying in the image structure or improving in the graininess and sharpness and in the color reproducibility. As to improvement of the color reproducibility, some techniques have been developed in past years, by which the reproducibility has been considerably raised. One of the techniques is the use of a colored coupler having an automasking function, described in US Patent No. 2,455,170. The colored coupler is principally used for raising the color reproducibility of a color negative film. The colored coupler is effective to compensate the unnecessary absorption of a dye formed from a yellow, magenta or cyan coupler used in the color negative film. It is made possible to considerably raise the color reproducibility by reducing impurity of reproduced color by imagewise compensating the unnecessary absorption of dye formed in the color negative film by the use of the colored coupler. As to color negative film, a technique of a development effect or an interlayer effect for raising the saturation of reproduced color has been proposed in, for example, Belgian Patent No. 710,344 and German Patent No. 2,043,934 for satisfying the requirement of more bright color reproduction. Furthermore, DIR compound is developed, for example U.S. Patent No. 3,277,554, as an application of the interlayer effect. The color saturation of the reproduced image is greatly improved by the DIR compound. Besides the improvement for realizing the color reproduction having a high chroma, some techniques have been proposed for accurately reproducing color just as is seen by human eyes. One of the techniques is based on the control of the spectral sensitivity distribution of the blue-, green- and red-sensitive layers, which is described in Japanese Patent Open to Public Inspection (JP O.P.I.) No. 5-150411. Some techniques have been proposed which are based on the difference between the spectral sensitivity distribution of the cone of the human eye and that of the color film. Generally, in color film, the distribution of spectral sensitivity of the blue-sensitive layer has a maximum sensitivity at a wavelength longer than that of the human eye, the distribution of spectral sensitivity of the green-sensitive layer has a maximum sensitivity at a wavelength a little longer than that of the human eye and the distribution of spectral sensitivity of the red-sensitive layer has a maximum sensitivity at a wavelength considerably longer than that of the human eye. Furthermore, the red-sensitive cone of the human eye has a negative sensitivity at about 500 nm. A color intervening between the primary colors can be reproduced to some degree of accuracy by finely controlling the spectral sensitivity distribution by selection of sensitizing dye and the interlayer effect by the use of a donor layer for adjusting the spectral sensitivity distribution of the color film to that of the human eye, cf. JP O.P.I. No. 61-34541. The color intervening between the primary colors is reproduced with difficulty by conventional color films. The reproducibility of a color film is improved so that the hue of the object can be accurately reproduced by these techniques. As above-mentioned, color reproducibility of color photography is steadily progressed. However, it is a fact that a further improvement in the color reproducibility is required for a next generation of color light-sensitive materials which are on a different level from usual light-sensitive materials. The reason for this is that a consumer is possibly disappointed about a print of a photograph taken by him. The consumer is often disappointed about a photograph of tender green leaves of trees, red flowers or distant view of mountains. When the consumer looks at the finished print of such the scenes, he is often disappointed since in the printed picture the color of the tender green leaves is darkened, the detailed gradation of the petals of red flowers is lost, and the distant mountains are made hazy and the cubic effect of them is lost, which produces scenes different from those expected or remembered by the consumer. Further, a light-sensitive material for preparation of a colour proof is described in European Patent Publication No. 0 737 889 A2. The light sensitive material has infrared-sensitive layer further than visible light-sensitive emulsion layers on a reflective support. Such a light-sensitive material is different from the light-sensitive material of the invention in the function and constitution thereof. As above-mentioned, the requirements of colour photography have not been satisfied only the accurate reproduction of vivid colour, and an ability of depiction capable of forming an image more than the expectation of the consumer so that the scene remembered by the consumer at the time of taking photograph is clearly reproduced, has been recently demanded. US 5,154,995 provides a silver halide colour photographic material which can form print images through a combination of conventional printing exposure and laser scanning exposure. The material comprises a support having coated thereon at least three silver halide emulsion layers forming yellow, magenta and cyan dye images. In addition, the material may have a further infra-red-sensitive layer which is intended to be suitable for printing images formed by the laser. EP-A-0588639 provides a silver halide colour photographic photosensitive material comprising on a support, a blue-sensitive layer containing a yellow coupler, a green-sensitive layer containing a magenta coupler and a red-sensitive layer containing a cyan coupler. The material further comprises an infra-red-sensitive layer containing yellow, magenta and cyan couplers intended to form a black image. EP-A-0713137 provides a silver halide photographic material suitable for producing a colour filter. The material comprises on a support, a blue-sensitive emulsion layer containing cyan and magenta couplers to form a blue image (but not a yellow coupler), the green-sensitive emulsion layer contains yellow and cyan couplers (but not a magenta coupler) to form a green image and the red-sensitive layer contains yellow and magenta couplers (but not a cyan coupler) to form a red image. The material further comprises an infra-red-sensitive emulsion layer containing a coupler which is intended to effect colour correction to be substantially black. SUMMARY OF THE INVENTION The object of the invention is to provide a silver halide colour photographic light-sensitive material which is excellent in scene depiction ability. Specifically, the object is to provide a silver halide colour photographic light-sensitive material by which the tender green of tree leaves can be vividly reproduced, scenes of distant mountains can be clearly reproduced, blue colour of blue sky and sea-surface can be really reproduced, and the light-sensitive material is excellent in the ability of depiction of the detail of red flowers and in the colour reproducibility of skin-colour having a low lightness. The above-mentioned object of the invention is attained by a silver halide colour photographic light-sensitive material comprising a transparent support having on one side thereof a cyan dye-forming coupler-containing red-sensitive silver halide emulsion layer, a magenta dye-forming coupler-containing green-sensitive silver halide emulsion layer, a yellow dye-forming coupler-containing blue-sensitive silver halide emulsion layer, a non-light-sensitive hydrophilic colloid layer and an invisible light-sensitive silver halide emulsion layer which is an infra-red-sensitive layer comprising a coloured coupler and/or a DIR compound. By "invisible light-sensitive" used herein is meant "infra-red-sensitive". DETAILED DESCRIPTION OF THE INVENTION In the invention, the invisible light-sensitive colour reproducibility improving layer is a silver halide emulsion layer sensitive to light having a wavelength within the range of from 400 nm to 700 nm. The sensitivity wavelength of the invisible light-sensitive colour reproducibility improving layer is preferably not less than 680 nm and not more than 850 nm, more preferably not less than 730 nm and not more than 780 nm. The infra-red light-sensitive emulsion layer comprises a coloured coupler or a DIR compound. It is preferable that the infra-red light-sensitive silver halide emulsion layer further comprises at least one of a yellow dye-forming coupler, a magenta dye-forming coupler and a cyan dye-forming coupler. The invisible light-sensitive colour reproducibility improving layer is preferably provided at a position nearer the support than that of a green-sensitive layer. The colour reproducibility of the light-sensitive material can be improved by adding a coloured coupler to the invisible light-sensitive layer so that a colour image is formed corresponding to invisible light coming from objects. For example, when a yellow-coloured magenta coupler is added into an infra-red-sensitive layer, a magenta image is formed according to infra-red rays coming from vegetation having green leaves. Consequently, the reproduction of green colour of the leaves of tree and grasses can be improved. The colour reproducibility of the light-sensitive material can be improved by adding a DIR coupler to the invisible light-sensitive layer so that an interimage effect is generated corresponding to invisible light coming from objects. For example, when a DIR coupler is added into an infra-red-sensitive layer, an interimage effect is generated according to infra-red rays coming from human skin with a low lightness or tanned skin. Consequently, the reproduction of skin colour can be improved. The colour reproducibility of the light-sensitive material can be further improved by adding a coupler and a coloured coupler to the invisible light-sensitive layer so that a colour image is formed corresponding to invisible light coming from objects. For example, when a magenta coupler and a yellow-coloured magenta coupler is added into an infrared-sensitive layer, a colour image is formed according to infra-red rays coming from a yellow flower. Consequently, the reproduction of yellow colour of the flower can be improved. The colour reproducibility of the light-sensitive material can be further improved by adding a coloured coupler and a DIR coupler to the invisible light-sensitive layer so that a colour image is formed and an interimage effect is generated corresponding to invisible light coming from objects. For example, when a yellow-coloured magenta coupler and a DIR coupler is added into an infra-red-sensitive layer, a magenta image is formed and an interimage effect is generated according to infra-red rays coming from green leaves of vegetation with a low lightness. Consequently, the reproduction of green colour of the vegetation can be improved. The colour reproducibility of the light-sensitive material can be further improved by adding both a coupler and a DIR coupler to the invisible light-sensitive layer so that a colour image is formed and an interimage effect is generated corresponding to invisible light coming from objects. For example, when a magenta coupler and a DIR coupler is added into an infrared-sensitive layer, a magenta image is formed and an intermimage effect is generated according to infra-red rays coming from green vegetation. Consequently, the reproduction of green colour of the vegetation can be improved. For example, when a yellow coupler is added into an infra-red-sensitive layer, a yellow image is formed in the infra-red-sensitive layer corresponding to infra-red rays coming from a purple flower, and the reproduced colour of the purple flower can be improved. For example when a magenta coupler is added to an infra-red-sensitive layer, a magenta layer is formed according to infra-red rays coming from vegetation having green leaves in the infra-red-sensitive layer. Consequently, the reproduction of green colour of leaves of trees and grasses can be improved. For example, when a cyan coupler is added to an infra-red-sensitive layer, a cyan image is formed according to infra-red rays coming from original objects. However, an amount of infra-red rays reflected from a water surface is smaller than that coming from another object. Consequently, reproduction of the blue colour of a water surface such as a sea surface can be improved. In the invention, the layer for improving a reproducibility of green colour of vegetation is a layer containing a silver halide emulsion which is infra-red sensitive and sensitive to reflection light from vegetation to improve the reproducibility of green colour of vegetation. Although a coupler, a coloured coupler or a DIR compound may be contained in the vegetation green colour reproducibility improving layer, a magenta coupler is preferably contained. The layer is affected by light of not less than 720 nm of inherent green colour of vegetation and forms a magenta image thereof so that the lightness and saturation of green colour can be raised. Such a vegetation green colour reproducibility improving layer has not been disclosed nor suggested in the past. In the invention, the color reproducibility improving layer for improving a reproducibility of lightness of red color is an invisible light-sensitive color reproducibility improving layer containing a silver halide emulsion and a DIR compound, which is sensitive to infrared rays and gives an inter-layer effect (IIE) by imagewise releasing a development inhibitor so as to inhibit the development in another layer. The reproducibility of the lightness of red color can be improved by the effect of this layer. For example, the invisible light-sensitive layer is sensitive to infrared rays reflected from a red object such as a red tulip flower and imagewise releases a development inhibitor. Thus unnecessary emphasize of red color can be inhibited. As a result of that, the reproduction of the detailed gradation in red color can be realized and the accuracy of the red color reproduction can be raised. Such a red color lightness improving layer has not been disclosed nor suggested in the past. In the invention, the color reproducibility improving layer for improving a reproducibility of hue of skin color is an invisible light-sensitive color reproducibility improving layer containing a silver halide emulsion and a DIR compound, which is sensitive to infrared rays and gives an inter layer effect (IIE) by imagewise releasing a development inhibitor so as to inhibit the development in another layer. Generally, the skin of a male strongly reflects light in the region of red to infrared compared with the skin of female. The invisible light-sensitive layer is sensitive to infrared rays reflected from the male skin and imagewise releases a development inhibitor. By the effect of this layer, turning reddish-brown of male skin color can be avoided and skin colors of male and female which are different in the lightness from each other can be naturally reproduced. Such a skin color reproducibility improving layer has not been disclosed nor suggested in the past. In the invention, the color reproducibility improving layer for improving a reproducibility of color of blue sky is a layer containing a silver halide emulsion which is sensitive to infrared rays contained in ordinary sunlight and almost not sensitive to blue sky light, and improves the reproducibility of color of sky. Although a colored coupler or a DIR compound may be contained in the sky blue color reproducibility improving layer, a colored coupler is preferably contained. For example, when a yellow-colored cyan coupler and a yellow-colored magenta coupler are contained in this layer, a cyan image and a magenta image of the object other than blue sky reflecting sunlight are formed since ordinary sunlight has energy in the infrared region. In contrast, the yellow color of the colored couplers remains in the portion of blue sky since the energy in the infrared region of blue sky or skylight is low. As a result of that, the reproduction of pure and deep color of blue sky can be realized. Such a blue sky color reproducibility improving layer has not been disclosed nor suggested in the past. In the invention, the color reproducibility improving layer for improving a reproducibility of color of the sea surface or a water surface is a layer containing a silver halide emulsion which is sensitive to infrared light, sensitive to ordinary sunlight and almost not sensitive to light reflected by the sea surface or the water surface, and improves the reproducibility of color of the sea surface or water surface. Although a colored coupler or a DIR compound may be contained in the sea surface or water surface color reproducibility improving layer, a colored coupler is preferably contained. For example, when a yellow-colored cyan coupler and a yellow-colored magenta coupler are contained in this layer, a cyan image and a magenta image of the object reflecting sunlight other than sea or water surface are formed since ordinary sunlight has energy in the infrared region. In contrast in the portion of sea or water surface, the yellow color of the colored couplers remains since the energy in the infrared region of light reflected by sea surface or water surface is low. As a result of that, the densities of magenta and cyan of the image of the sea or water surface are raised and the lightness of that is lowered on the finished print. Accordingly the reproduction of pure and deep color of the sea surface or water surface can be realized. Such a sea surface or water surface color reproducibility improving layer has not been disclosed nor suggested in the past. In the invention, the silver halide emulsion to be contained in the invisible light-sensitive color reproducibility improving layer has a maximum spectral sensitivity at a wavelength within the range of from not less than 680 nm to not more than 850 nm.

There is no specific limit as to the kind of dyes. In the case where a polyester film is used as the support, one having an excellent heat resisting property is preferable. For example, anthraquinone-type dyes can be mentioned. For color hue of the dye, in the case when prevention of light piping is aimed at, as is the case in the popular light sensitive materials, gray dye is preferable.

In the light-sensitive material of the invention, it is preferred that the sensitivity of the infrared-sensitive emulsion layer is lower than those of the red-sensitive, green-sensitive and blue-sensitive emulsion layers. When the sensitivity of the infrared-sensitive emulsion layer is higher than that of the visible light-sensitive layers, the reproduced color of the object tends to become unnatural since the color compensation effect of the infrared-sensitive layer affects excessively It is preferred that the sensitivity of the infrared-sensitive layer is not more than 80%, preferably not more than 50%, more preferably 1 to 40%, of the sensitivity of a visible light-sensitive emulsion layer having the lowest sensitivity among the red-, green- and blue-sensitive emulsion layers. In the above-mentioned, the sensitivity is based on the light amount of the exposure necessary to obtain an image density of 0.1 on the minimum density of the light-sensitive material.

Pieces of thus obtained sample were each exposed to a prescribed amount of light of wavelength in 5 nm increment from 600 nm to 900 nm, respectively, and processed by a color processing system CNK-4, manufactured by Konica Corporation. The spectral sensitivity curve of the infrared-sensitive layer was drawn based on the light amount necessary to a density of the minimum density plus 0.3 measured by blue light. The wavelength of light, at which the sensitivity of the infrared-sensitive layer was highest, was determined based on the spectral sensitivity curve. In Samples 102 and 103, the relation of the sensitivities of each emulsion layers were blue-sensitive layer > green-sensitive layer > red-sensitive layer > infrared-sensitive layer, and the sensitivity of the infrared-sensitive layer was 5% of the red-sensitive layer. Samples 101 to 103 were each slit to 135 standard size and packed in a cartridge. A scene including a man having a 18% gray chart and green leaves of tree as a background was photographed using the samples with a camera, Konica Hexar, manufactured by Konica Corporation, under sunlight. The samples were processed by the color processing system CNK-4, and dried to obtain processed film samples. Thus obtained negatives were printed on Konica Color Paper Type QAA6 by an enlarger Chromega. The sheets of the color paper were processed by a color paper processing system CPK-2-21, manufactured by Konica Corporation, to obtain finished prints. The printing condition was adjusted so that the color of the 18% gray chart was reproduced to be gray. L*, a* and b* of the reproduced colors of the green leaves and the skin were determined according to the chromaticity diagram system of CIE 1976 by colorimeter CMS-1200 manufactured by Murakami Color Laboratory. Thus obtained results are shown in Table 1.

In the reproduction of the skin color, a higher value of L* is preferred a little, and higher absolute values of a* and b* are preferred. Further a higher value of C* calculated by the following equation, which is corresponding to the distance from the point of the color to the origin in the chromaticity diagram, is preferred since the higher value of C* indicates a vividly reproduced color. C* = (a*) 2 + (b*) 2 In the reproduction of skin color, a higher value of L* and higher absolute value of a* and b* are preferred. A color having a higher C* value is preferred since the reproduced color is vivid. In Table 1, the reproduction of the green leaves of trees and that of the skin color were evaluated according to the following rankings. Reproduction of green color of tree leaves D: Darkened C: Darkened a little B: Vividly reproduced A: Brightly and vividly reproduced Reproduction of skin color C: Insufficient in redness B: Naturally reproduced A: Naturally and brightly reproduced Besides, the prints prepared by Samples 101 to 103 were subjectively evaluated by twenty observers. As a result, all the observers answered that the print using Sample 103 was preferred.

In Samples 201 and 202, the relation of the sensitivities of each emulsion layers were blue-sensitive layer > green-sensitive layer > red-sensitive layer > infrared-sensitive layer, and the sensitivity of the infrared-sensitive layer was 3% of the red-sensitive layer. Thus obtained samples were slit to 135 standard size and packed in cartridges. A scene including a distant view of mountains, green leaves of trees and a 18% gray chart was photographed using the samples with a camera, Konica Hexar, manufactured by Konica Corporation, under clear sky. The samples were processed by a color processing system CNK-4, manufactured by Konica Corporation, and dried to obtain processed samples. Thus obtained negatives were printed on Konica Color Paper Type QAA6 by an enlarger Chromega. The sheets of the color paper were processed by a color paper processing system CPK-2-21, manufactured by Konica Corporation, to obtain finished prints. The printing condition was adjusted so that the color of the 18% gray chart was reproduced to be gray. L*, a8 and b* were determined in the same manner as in Reference Example 1. The landscape depiction ability was evaluated by the fluctuation of green density AD measured by green light in the image of the distant mountains measured by scanning by a microdensitometer. Thus obtained results are shown in Table 2.

In Sample 801, the relation of the sensitivities of each emulsion layers were blue-sensitive layer > green-sensitive layer > red-sensitive layer > infrared-sensitive layer, and the sensitivity of the infrared-sensitive layer was 4% of the red-sensitive layer. Thus obtained samples were slit to 135 standard size and backed in cartridges. The upper part of the bodies of a male and a female and a red flower of tulip were photographed using a strobe flash light in a studio using the samples with a camera Konica Hexar, manufactured by Konica Corporation. The samples were processed by a color processing system CNK-4, manufactured by Konica Corporation, and dried to obtain processed samples. Thus obtained negatives were printed on Konica Color Paper Type QAA6 by an enlarger Chromega. The sheets of the color paper were processed by a color paper processing system CPK-2-21, manufactured by Konica Corporation, to obtain finished prints. The printing condition was adjudged so that the color of the female skin color was aptly printed. L*, a* and b* of the reproduced colors were measured by the same manner as in Reference Example 1. The gradation in the petal of the red tulip flower is evaluation by measuring the density fluctuation of the density measured by green light AD in the reproduced image of it, by scanning by a microdensitometer. Thus obtained results are shown in Table 8. As to gradation reproduction of the red tulip, a higher value of ΔD is preferred. In the reproduction of the color of male skin, a higher value of b* is preferable. Besides, the prints prepared by Samples 101 and 803 were subjectively evaluated by twenty observers. As a results, all the observers answered that the print using Sample 801 was preferred.
