Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a multilayer silver halide color light-sensitive material, and more specifically, it has good color development, improved color reproducibility, and improved image storage stability. , a multilayer silver halide color photosensitive material (hereinafter referred to as photosensitive material) containing a novel combination of couplers that does not disrupt color balance (= related (prior art)) A photosensitive layer consisting of three types of silver halide emulsion layers which are C-selectively sensitized to be sensitive to light and red light is coated on a support in a multilayer groove structure.For example, so-called color Photographic paper (U lower blade color is called -par) is usually coated with a red-sensitive emulsion layer, a green-sensitive emulsion layer, and a blue-sensitive emulsion layer in order from the exposed side. In between (=, color mixing prevention, ultraviolet absorbing intermediate layer, preservation layer, etc.) are provided.

In addition, in so-called color positive films, the green, bright emulsion layer, red-sensitive emulsion layer, and blue-sensitive emulsion layer are generally formed in order (from the side farthest from the support, that is, from the exposed side) (two coated (/-), color poor).゛In film, there are many different order sequences.
Generally, a blue-sensitive emulsion layer, a green-sensitive emulsion layer, and a red-sensitive emulsion layer are coated in this order from the exposed side, but it has two or more emulsion layers with the same color sensitivity but different sensitivities. There are some photosensitive materials in which emulsion layers with different color sensitivities are arranged between the emulsion layers, and some have a bleachable yellow filter layer, an intermediate layer, etc., and some have a protective layer on the outermost layer. provided.

In order to form a color photographic image, three photographic couplers of yellow, magenta and cyan are contained in a photosensitive material, and the exposed photosensitive material is subjected to color development processing using a so-called color developing agent. The oxidized product of the aromatic primary amine undergoes a coupling reaction with the coupler (a chromogenic element is produced from the second stage, but the coupling rate at this time is as high as possible to provide a high-quality color density within a limited development time). Preferably, the coloring dyes are bright cyan, magenta, and yellow dyes with little side absorption, and are suitable for color photography UT (required to give an image) with good color reproducibility. be done.

On the other hand, the formed color photographic images are required to have good storage stability under various conditions, and in order to meet this requirement, the rate of fading or discoloration of color pigments of different hues is slow; It is also important that the speed of fading be as uniform as possible over the entire image range, and that the color balance of the remaining dye image does not change.

The cyan dye image deteriorates greatly due to long-term fading due to the effects of heat and heat, and is likely to cause color and two-lance fluctuations, so improvements are strongly desired. Conventionally, there has been a strong contradictory tendency that if the dye is resistant to dark fading, the hue is poor, and only a cyan dye image is produced which is susceptible to photofading and photobleaching.Therefore, new combinations of couplers have been desired.

In order to partially solve these problems, specific combinations of couplers have been proposed.

However, with these combinations (well, the color development that can be obtained is insufficient, or the hue of the color pigment is poor, resulting in negative effects on color reproduction. It is desirable to improve the color balance of the remaining pigment, which may cause deterioration due to exposure to light or heat.

The present invention aims to solve the above-mentioned problems at the same time.More specifically, the first object of the present invention is to achieve good color development through a novel combination of cyan, magenta, and yellow couplers. The color reproducibility of the resulting color photographic image is improved, and Ii! The object of the present invention is to provide a silver halide color photographic light-sensitive material which has improved image storage stability and, in particular, whose color balance does not change over a long period of time either in the dark or when exposed to light. The first object of the present invention is to have good image storage stability even when stored for a long period of time in at least one of high temperature and high humidity atmospheres, and to maintain high color retention not only in highly colored areas but also in one gradation area. 2.
