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, more specifically, a novel 2-equivalent yellow coupler which can be produced at low cost, has excellent color developability, and has excellent image storability. The present invention relates to a silver halide color photographic light-sensitive material used for a layer.

[0002]

BACKGROUND OF THE INVENTION Recently, in silver halide color photographic light-sensitive materials (hereinafter also simply referred to as color light-sensitive materials),
Instead of the traditional 4-equivalent coupler, which required 4 atoms of silver to form the dye of the molecule, introduce a suitable substituent at the coupling position (active site) of the coupler that reacts with the oxide of the developing agent. As a result, a 2-equivalent coupler in which two atoms of silver are sufficient to form one molecule of dye tends to be used.

However, the demands on couplers have become more and more stringent with the progress of color light-sensitive materials, and not only color development but also color reproducibility, image storability, solubility in low-boiling and high-boiling solvents, and dispersion stability. Further improvement in sex is required.

As a technique for improving color reproducibility and color development, a yellow coupler having a heterocyclic compound having a cyclic imide structure as a leaving group and an alkoxy group introduced at the 2-position of the anilide portion is known. . For example, JP-A-52-115219 discloses a yellow coupler having an alkoxy group at the 2-position of the anilide portion and having a hydantoin group or a urazole group as a leaving group.
However, since this coupler is a sulfamoyl group existing as a ballast group, it has a drawback that it is extremely inferior in light resistance.

[0005] As one having further improved light resistance while maintaining good color reproducibility, for example, JP-A-50-63 is used.
No. 41, No. 63-123047, No. 3-125140, No. 3-125141, and Japanese Patent Application No. 2-245949. Yellow couplers having an alkoxy group, an acylamino group at the 5-position, and a hydantoin group or a urazole group as a leaving group are known. However, these couplers are slightly inferior in color forming property, and therefore, they cannot satisfy the recent demand for high color forming.

As one means for further improving the color developability, it is known to increase the hydrophilicity of the leaving group. For example, in JP-A-50-132926, an alkoxide group is substituted at the 2-position of an anilide moiety, an alkylacylamino group substituted at the 5-position with an aryloxy group, and a urazole having a nitrogen atom as a leaving group which is unsubstituted. Yellow couplers having groups are described. Further, JP-A-3-209241,

Nos. 3-211549 and 3-229248 disclose that an aryloxy group at the 2-position and an unsubstituted alkylacylamino group at the 5-position of the anilide moiety and an unsubstituted nitrogen atom as a leaving group. Yellow couplers having a hydantoin group are described. However, in these couplers, the hydrophilicity of the leaving group is canceled by the aryloxy group present as a substituent, and the color developability has not yet reached a sufficiently satisfactory level.
