Description

[Detailed description of the invention]

0001

[Field of Industrial Application] The present invention relates to a silver halide color photographic light-sensitive material, and more specifically, the present invention relates to a silver halide color photographic material that has a smooth gradation from a high exposure area to a low exposure area and has excellent print reproducibility. Regarding photographic materials.

0002

[Background of the invention] Silver halide color photographic materials include
Usually, yellow couplers, cyan couplers, and magenta couplers are used in combination. Among these, 5-pyrazolone magenta couplers are widely used as magenta couplers. 5-pyrazolone magenta couplers have various problems in color reproduction because the dye formed by development has sub-absorption near 430 nm. New magenta couplers have been researched to solve this problem, such as U.S. Pat. No. 3,725,065 and U.S. Pat.
, No. 761, No. 3,758,309, No. 3,725,
Pyrazolotriazole couplers such as those disclosed in No. 067 have been developed.

These couplers have many advantages such as low side absorption, good color reproducibility, and excellent color development.

By the way, general color negative films are loaded into cameras and used to photograph various subjects under various conditions. It is designed to have a wide latitude so that images can be recorded even if the exposure is slightly off from the proper exposure, or more image information can be recorded. That is, by using two or more types of silver halide emulsions having the same color sensitivity but different sensitivities, image information from a high exposure area to a low exposure area can be recorded.

That is, when producing the color negative film, a characteristic curve from a high exposure area to a low exposure area (the horizontal axis is -logE, E: exposure amount, and the vertical axis is image density D) is used.
Color negative films using the above-mentioned pyrazolotriazole magenta couplers are required to have a smooth color (shown by With this method, a density close to the maximum density was obtained, and the gamma decreased in the high exposure range, making it difficult to obtain a smooth custom curve. In order to overcome this difficulty, attempts have been made to use compounds that release development inhibitors during development (hereinafter referred to as DIR compounds), but these have had the drawback of causing a decrease in sensitivity in low exposure areas.

[0006] Furthermore, when these pyrazolotriazole couplers are used, for example, in color negative films and printed on paper, the hue of the finished color paper may vary depending on the printer equipment (hereinafter referred to as printer) used. It was found that there was a discrepancy between printers (hereinafter referred to as inter-printer variation).

[0007] Although this phenomenon has been observed in other conventional couplers, the degree of the phenomenon was extremely small and was not a problem. However, it has been found that when a pyrazolotriazole coupler is used, the difference in hue of the finished color paper due to differences in printers becomes a non-negligible level.

[0008] This phenomenon is thought to be mainly due to the following reasons. That is, when printing from color negative film to color paper using a printer, the printer first measures (1) the blue density, green density, and red density of the color negative film, and (2) measures the blue density, green density, and red density of the color negative film.
) These measured values are then converted into an exposure amount for the color paper, and (3) the color paper is exposed with this exposure amount. Various printers are commercially available and in use on the market, and depending on the model of these printers, the spectral sensitivity of the detector used for photometry (1) may differ, and due to the spectral absorption characteristics of the coloring dye in the color negative film, For example, a hue shift may occur because the half-width is too small or the spectral absorption characteristics vary depending on the concentration.

Many of the above-mentioned pyrazolotriazole magenta couplers have spectral absorption characteristics that vary greatly depending on concentration, and this is one of the reasons why the variation between printers increases when pyrazolotriazole magenta couplers are used for negative films. It is thought that there is one.

[0010] Therefore, it has been desired to develop a technique that provides excellent gradation and reduces printer-to-printer variation in silver halide color photographic light-sensitive materials containing pyrazolotriazole magenta couplers.

[0011]
