Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a silver halide color photographic light-sensitive material having excellent color forming properties and improved color reproducibility.

(Background of the Invention) Generally, among yellow, magenta, and cyan color-forming dyes that form a subtractive color photographic image, a yellow dye is
400-500 nm, magenta dye 500-600 nm, cyan dye
Although the main absorption region is the wavelength range of 600 to 700 nm,
It is well known that the absorption of these coloring dyes actually spreads to other adjacent regions, which is one of the causes of decreasing the purity of each color.

In particular, in the internal color photographic light-sensitive material, the couplers used for forming the respective color forming dyes are arranged in specific layers in combination with silver halide emulsions having specific spectral sensitivities. There is. In the production of such a light-sensitive material, in order to prevent the above-mentioned coupler from diffusing into other emulsion layers, a fat-soluble substituent having a large molecular weight is incorporated in the coupler molecule, and this is dissolved in a solvent having a high boiling point. After being dispersed in a hydrophilic colloid in the form of colloidal particles, it is added to a photographic emulsion. This method is the most general method for preventing the diffusion of couplers, and it is possible to obtain a coloring dye having excellent diffusion resistance and spectral absorption characteristics. On the other hand, it is generally known that the property of the high boiling point solvent affects the spectral absorption performance of a color image, and for example, JP-B-48-32727 discloses a 5-pyrazolone type magenta-forming coupler and an alkyl phosphate ester. It is described that a color-developed image with little absorption for red light can be obtained by the combination with.

However, even with such a method, in the magenta coloring dye, absorption on the long wavelength side exists in the red light region, so that a reddish object has a muddy color on the image. Therefore, in order to obtain a dye image with further improved color reproducibility, the long-wave end of spectral absorption must be significantly shifted to the short-wave side. On the other hand, the spectral absorption of a yellow color image has a large optical density with respect to green light, which is a serious problem in terms of color reproducibility. For example, a photographic image obtained from a bright yellow subject such as lemon is not reproduced as well as an orange-yellow image. In order to improve the reproducibility of such a yellow image, it is necessary to significantly shift the long-wave end of the spectral absorption of the yellow dye image to the short-wave side. As above,
No silver halide photographic light-sensitive material having a yellow dye image or a magenta dye image in which the long wave end of spectral absorption is shifted to the short wavelength side has been found yet.

(Object of the Invention) An object of the present invention is to provide a silver halide color photographic light-sensitive material excellent in color reproducibility by obtaining a dye image which is excellent in color development and in which the long-wave end of spectral absorption is shifted to the short-wave side. Especially.
