Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a silver halide color photographic light-sensitive material which has excellent color reproducibility and rapid processability, and which provides a sufficient maximum density.

[Background of the Invention] After a silver halide photographic material is exposed to light and subjected to color development processing, an oxidized aromatic primary amine color developing agent and a dye-forming coupler react to form a dye. A color image is formed.

Generally, this photographic method uses a subtractive color reproduction method to form yellow, magenta and cyan color images.

Phenols or naphthols have been widely used as cyan image forming couplers.

However, cyan images obtained from conventionally used phenols and naphthols have a serious problem in color reproduction. The reason is that the absorption is not sharp on the short wavelength side, and the edge region also has unnecessary absorption, that is, asymmetric absorption. As a result, in the case of negatives, it is necessary to correct the irregular absorption by masking or the like, and in the case of paper, there is no means for correction, and the current situation is that color reproducibility is significantly deteriorated.

In order to improve color reproducibility, the inventors of the present invention have conducted various studies and as a result have discovered a cyan coupler with a novel structure. As will be described later, this coupler has good absorption on the short wavelength side, and in terms of color reproduction, cyan color reproduction (hue reproduction) is greatly improved.

However, it has been found that the improvement in color reproduction achieved by this coupler is still not at a fully satisfactory level in rapid processing, and that this coupler also has the drawback of not being able to obtain a sufficient maximum density.

[Object of the Invention] The present invention has been made in view of the above, and an object of the present invention is to provide a silver halide color photographic light-sensitive material that is excellent in color reproducibility, rapid processability, and provides a sufficient maximum density. That's true.

[Structure of the Invention] The above-mentioned object of the present invention is to have a photographic constituent layer including at least one high chloride silver halide emulsion layer on a support, and in the photographic constituent layer, the following general formula [I] is present.

Silver halide emulsions contain halide ions and silver ions,
They may be mixed at the same time, or one may be mixed into the liquid in which the other is present.

The silver halide emulsion according to the present invention may be a mixture of two or more separately formed silver halide emulsions.

A practical print was obtained by processing in the same manner as above. Printer conditions during printing were set for each sample so that gray on the color checker turned gray on the print.

The color reproducibility of the obtained practical prints was visually evaluated. The results are summarized in Table-1.

Margin Table-1 below *I Em-1: Silver chlorobromide containing 90% AgBr *2
Silver chlorobromide (high chloride silver halide) containing Em-2+AgBr 0.1% ∆ Poor color reproducibility (hue, saturation)○ Good color reproducibility (hue, saturation)◎ Color reproducibility (hue) , saturation) Very good As is clear from Table 1, the sample Nα1 using the force 1r outside of the present invention
Although a high maximum density can be obtained, the color reproducibility is insufficient, and these problems cannot be improved even if the silver halide emulsion used is changed to the high chloride silver halide of the present invention.

On the other hand, samples Na3, No. 7, No. 9, in which the coupler of the present invention was used in place of CG-1 in sample No. 1, had an insufficient maximum density although the color reproducibility was greatly improved.

On the other hand, sample No. 4, Nα6, N(1
No. 8, NQ10, No. 11, Ki 12, k13, and No. 14 have sufficiently high maximum densities, and further improvement in color reproducibility is observed.

[Effects of the Invention] According to the present invention, it is possible to provide a silver halide color photographic light-sensitive material that is excellent in color reproducibility and rapid processability and provides a sufficient maximum density.
