Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a silver halide color photographic light-sensitive material, and more specifically, it is excellent in stagnation of a coating solution at the time of production, excellent storability of a light-sensitive material, color developability, color reproducibility and processing variability. The present invention relates to an excellent silver halide color photographic light-sensitive material.

[0002]

2. Description of the Related Art In a silver halide photographic light-sensitive material for direct viewing, such as color photographic paper, a combination of a yellow coupler, a magenta coupler and a cyan coupler is usually used as a color forming agent for forming a dye image. Used. These couplers are required to have basic properties such as color reproducibility, color developability and image storability in dye images to be obtained. In recent years, in particular, color reproduction is performed to faithfully reproduce the original color of the object. There is a growing demand from users to improve the quality.

To date, phenols or naphthols have been widely used as cyan image forming couplers.

However, the cyan image obtained from the conventionally used phenols and naphthols has a serious problem in color reproduction. That is, the sharpness of absorption on the short wave side is poor, and unnecessary absorption, that is, irregular absorption, is also present in the green region. As a result, it is unavoidable to correct irregular absorption due to masking or the like in the negative, and in the case of paper, there is no means for correction, and color reproducibility is considerably deteriorated at present.

For the purpose of improving color reproducibility, Japanese Patent Laid-Open No. Sho 64-64
-554, 63-250649, 63-250.
No. 650 and the like propose a pyrazoloazole type cyan coupler.

However, these couplers show good color reproducibility because electron-withdrawing groups and hydrogen-bonding groups are introduced in order to satisfy the absorption wavelength of the color-forming dye formed. However, the level of coupling activity was not sufficiently satisfactory, and color development and color reproducibility were not simultaneously satisfied.

Further, in recent years, the printing process and the developing process of the light-sensitive material for color photographing and printing have been shortened and accelerated, and the stability of the process is more and more required. .

In particular, the change in photographic performance associated with the change in the concentration of processing liquid components during continuous processing has become an increasingly serious problem in rapid processing.

However, the reality is that a silver halide photographic light-sensitive material satisfying this requirement has not yet been found.

[0010]

SUMMARY OF THE INVENTION The object of the present invention is to provide a silver halide color which is excellent in stagnation of a coating solution during production, excellent storability of a light-sensitive material, color development and color reproducibility and is excellent in processing variability.
