Description

Detailed Description of the Invention

[0001]

FIELD OF THE INVENTION The present invention relates to a silver halide color photographic light-sensitive material, and more particularly to a silver halide color photographic light-sensitive material having high sensitivity and excellent color reproducibility.

[0002]

2. Description of the Related Art A conventional silver halide color photographic light-sensitive material is exposed to light and then subjected to color development processing to react with an oxidation product of a para-phenylenediamine color developing agent and a coupler to form a dye, thereby forming a color image. It is formed.

Generally, in this photographic method, color reproduction by a subtractive color method is used to form a yellow, magenta, and cyan color image.

Typical examples of cyan dye-forming couplers (cyan couplers) are phenols and naphthols. Among them, naphthols are capable of sufficiently long-wavelength and have high coupling activity, so that they can be used in a color negative film. used.

Conventionally, naphthols substituted with a carbamoyl group at the 2-position have been used, but cyan dyes of this type are susceptible to reductive bleaching, and when treated with a tired bleaching solution, there is a problem that the color density decreases. .

In contrast, US Pat. No. 3,488,19
2-Arylcarbamoyl-1 described in No. 3 etc.
-The naphthol-based compound has the advantage that the reduction of the color density due to the fatigue bleaching solution does not easily occur, but on the other hand, the maximum absorption wavelength of the image shifts significantly to the short wavelength side in the high color-dye concentration range, which is disadvantageous in color reproduction. Was.

Japanese Unexamined Patent Application Publication No. Sho 6 (1994) aimed at overcoming such drawbacks
The 2-arylcarbamoyl-1-naphthol compounds described in, for example, 3-83747 have a characteristic that a remarkable short-wave shift of the maximum absorption wavelength does not easily occur even in the high color density range, but the current general color negative color development. In the development process, the maximum absorption wavelength is often longer than 700 nm, which is not preferable for color reproduction. In addition, the color forming property is still insufficient in response to the recent demand for higher sensitivity.

On the other hand, as a means for improving the color reproducibility and sharpness of a silver halide color photographic light-sensitive material, it is well known to use a DIR compound which reacts with an oxidant of a color developing agent to release a development inhibitor. There is. In general, a DIR compound is added to an emulsion layer to improve color reproducibility and sharpness by utilizing an inter-image effect between layers and an edge effect between layers and layers.

However, with the recent demand for higher sensitivity of silver halide color photographic light-sensitive materials, the speed of the couplers used has been increased, and the conventional DIR has a problem that it is difficult to obtain a sufficient improvement effect. .

As can be seen from the results shown in Table 4, when only the cyan coupler according to the present invention is replaced, the sensitivity of the red photosensitive layer is increased but the interlayer effect given to the green photosensitive layer is reduced.
