Description

Description: FIELD OF THE INVENTION The present invention relates to a silver halide color photographic light-sensitive material excellent in color reproducibility and image storability.

[Background of the Invention]

After the silver halide photographic light-sensitive material is exposed to light, color development is performed, whereby the oxidized aromatic primary amine color developing agent reacts with the dye-forming coupler to form a dye, thereby forming a color image. You.

Generally, in this photographic method, color reproducibility by a subtractive color method is used, and yellow, magenta, and cyan color images are formed.

So far, phenols or naphthols have been widely used as cyan image forming couplers.

However, cyan images obtained from conventionally used phenols and naphthols have a large problem in color reproduction. That is, the sharpness on the short wavelength side of the absorption is poor, and the green region also has unnecessary absorption, that is, irregular absorption.
As a result, in the negative, irregular absorption due to masking or the like must be corrected, and in the case of paper, there is no correction means, and the color reproducibility is considerably deteriorated at present.

Further, the dye images obtained from phenols and naphthols which have been conventionally used have some problems in preservability. For example, U.S. Pat.
The dye images obtained from the 2-acylaminophenol cyan couplers described in US Pat. Nos. 7,531 and 2,423,730 generally have poor heat fastness, and the 2,5-- US Pat. Nos. 2,369,929 and 2,772,162 describes. Dye images obtained from diacylaminophenol cyan couplers generally have poor light fastness, and dye images obtained from 1-hydroxy-2-naphthamide cyan coupler generally have insufficient light and heat fastness.

On the other hand, recently, in the field of printing plate making, a proofing system (so-called color proof) using a silver halide color photographic light-sensitive material (hereinafter, referred to as a color photographic material) has been performed because of advantages such as simplicity, low cost, and short time.
