Title: Light-sensitive silver halide color photographic material

Description:
This application is a continuation of application Ser. No. 333,832 filed Apr. 5, 1989, now abandoned, which is a continuation of application Ser. No. 170,397, filed Mar. 18, 1988, now abandoned. 
    
    
     FIELD OF THE INVENTION 
     The present invention relates to a light-sensitive silver halide color photographic material capable of forming a dye image of which the dyes formed are so satisfactory in the spectral absorption characteristic as to be excellent in the color reproducibility as well as in the image preservability and which has a high maximum density. 
     BACKGROUND OF THE INVENTION 
     In light-sensitive silver halide photographic materials for use in making images for direct appreciation. particularly color photographic paper and the like, as the dye-forming couplers therefor, generally, yellow couplers, magenta couplers and cyan couplers are used in combination. As the magenta coupler out of these couplers, pyrazoloazole-type magenta couplers have been developed in recent years. 
     The pyrazoloazole-type magenta coupler, unlike those 5-pyrazolone-type magenta couplers, which have conventionally been used, is characteristic of being advantageous in the color reproducibility because the dye formed therefrom has no secondary absorption in the proximity of 430 nm. 
     On the other hand, those yellow couplers which are used generally along with the above-mentioned magenta coupler have disadvantages that the absorption maximum wavelength of the dye formed therefrom is generally positioned on the longer wave side than the absorption wavelength desirable for the color reproducibility, and the absorption of the dye in the longer wavelength region exceeding 500 nm does not sharply diminish to nil. 
     Accordingly, in such a silver halide light-sensitive photographic material, there has been a problem that, even if a pyrazoloazole-type coupler is used as a magenta coupler, any adequate color reproducibility for colors such as yellow, green and yellowish green cannot be obtained due to the above-mentioned disadvantages of the yellow coupler. For this reason, there has been a demand for the realization of a yellow coupler wherein the absorption maximum wavelength of the dye formed therefrom be positioned on the further shorter wavelength side and the absorption of the dye in the longer wavelength side exceeding 500 nm sharply diminish. 
     As has been mentioned above, it is the present situation that any light-sensitive silver halide photographic materials excellent in the overall color reproducibility for all colors are still not found. 
     SUMMARY OF THE INVENTION 
     It is an object of the present invention to provide a light-sensitive silver halide photographic material capable of forming a dye image of which the dyes formed are so improved on the spectral absorption characteristic thereof as to be excellent in the color reproducibility for all colors as well as in the dye image preservability and color formability. 
     The above object of this invention is accomplished by a silver halide light-sensitive photographic material comprising a support and, provided thereon, at least one blue-sensitive silver halide emulsion layer, at least one green-sensitive silver halide emulsion layer and at least one red-sensitive silver halide emulsion layer, in which said green-sensitive silver halide emulsion layer contains a magenta coupler having the following Formula [M-1], and said blue-sensitive silver halide emulsion layer contains a yellow coupler having the following Formula [Y-I]: ##STR3## wherein Z is a group of non-metal atoms necessary to form a nitrogen-containing heterocyclic ring, provided that the ring formed by the Z may have a substituent: X is a group capable of being split off upon the reaction with the oxidation product of a color developing agent; and R is a hydrogen atom or a substituent. ##STR4## wherein R 21  is an alkyl group or a cycloalkyl group: R 22  is an alkyl group, a cycloalkyl group, an acyl group or an aryl group; R 23  is a group substitutable to the benzen ring; n is an integer of 0 or 1; R 24  is an organic group containing one linkage group having a carbonyl or sulfonyl unit; J is a ##STR5## group or a ##STR6## group (wherein R 25  is a hydrogen atom, an alkyl group, an aryl group or a heterocyclic group): and X 1  is a group capable of being split off upon the reaction with the oxidation product of a color developing agent.

     As is apparent from the results shown in Table-2, in comparison with Sample No. 1, in which the non-invention yellow coupler and magenta coupler are used, Sample No. 2, in which the magenta coupler alone is replaced by the pyrazole-type coupler of this invention, is recognized to have been improved on the color reproducibility for the respective blue, green, red and magenta colors, while Sample No. 3, in which the yellow coupler alone is replaced by the yellow coupler of this invention, is recognized to have been improved on the color reproducibility for the respective green, yellow and yellow-green colors. However. any of the above samples are not considered to have adequate colors from the stand point of color reproducibility, so that they cannot be regarded as photographic light-sensitive materials collectively excellent in the color reproducibility. 
     In contrast, Samples Nos. 4 through 15, in which the magenta coupler and yellow coupler used are all of this invention, are excellent in the color reproducibility for all colors, so that they prove the effect of this invention to be excellent. 
     Further, as is apparent from Table 2, Samples Nos. 4 through 15, in which both the magenta coupler of this invention and the yellow coupler of this invention are combinedly used, have sufficiently high maximum densities as compared with those of Samples No. 1 through 3, in which the noninvention magenta coupler and/or the non-invention yellow coupler are used, and in addition, in the resistance to light. the former samples are equal to or better than the latter samples.
