Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a silver halide color photographic light-sensitive material, and particularly to a color light-sensitive material for photographing having excellent color reproducibility and graininess.

[Background of the invention]

In recent years, silver halide color photographic materials have made remarkable progress, and sensitive materials with higher sensitivity and higher image quality have been released one after another.
Small 7-ohm film (
Although it has become possible to obtain reasonably good photographs even with high-magnification prints from (for example, 110 film, disc film), the quality has not yet reached a level that satisfies general users. It is desired to further improve the image quality of photographic light-sensitive materials, particularly to improve color reproducibility and graininess.

In recent years, 2-phenylureido type phenolic cyan couplers have been used as cyan couplers for color negative light-sensitive materials, but these couplers do not react well when processed with weak oxidizing bleaching solutions or exhausted bleaching solutions. Although it has the advantage that there is almost no decrease in color density caused by reduction fading, it has the disadvantage that the absorption in the edge region is large, which deteriorates color reproducibility.

As a ureido type phenolic cyan coupler with improved absorption in the green part, JP-A-63-159848 and JP-A-63-159848
There are couplers described in No. 161450, No. 63-161451, etc., but when these couplers are used in a multilayer color photosensitive material having a blue-sensitive layer, a green-sensitive layer, and a red-sensitive layer, there is no improvement in the green area at all. It became clear that this was insufficient.

It was also revealed that it had no effect on improving graininess.

The density was measured using a 310 model densitometer manufactured by ITE, and the green density when the red density was the minimum density + 1.5 was determined and is shown in Table 2. The lower the green density, the better the color reproducibility.

In addition, the results of determining a value 1000 times the RMS, which is commonly used to express graininess, are also listed.

For RMS, measure the point of Dmin (minimum concentration) + 1.0 using a microdensitometer (PDM-5A manufactured by Konica Corporation).
The measurement was performed using an aperture area of 250 μm2.

As is clear from Table 2, the samples configured according to the present invention have improved color reproducibility and graininess.

Furthermore, the effect of the present invention was also observed when cyan coupler 38 was used instead of cyan coupler 14 in the fourth layer of sample 108.
