Description

[Detailed description of the invention]

Industrial Application Fields The present invention provides a halogenated dye image that exhibits high sensitivity and color development, and which provides a yellow dye image that does not cause a decrease in the color development of the coupler even when processed with a color developer from which benzyl alcohol has been removed. This invention relates to silver color photographic materials. [Prior Art] Generally, in a silver halide color photographic light-sensitive material, exposed silver halide grains are reduced with an aromatic primary amine color developing agent, and at this time, the oxidized product of the color developing agent is produced. A dye image can be obtained by coupling the dyes with couplers that form yellow, magenta, and cyan dyes. Open-chain active methylene yellow couplers are widely used to form the yellow dye. Due to the recent rise in the price of silver, the manufacturing cost of silver halide color photographic materials has increased, and there is therefore a strong need for the development of couplers that require a small amount of silver, that is, can save silver. . In addition, the development of techniques to increase the reactivity of couplers is a constant challenge for those skilled in the art, and it has been found that there is no difference in the density of dyes obtained by processing with a fixed amount of silver and a fixed molar amount of coupler. As is already well known, the worse the color development, the more unreacted residual coupler there is. That is, when setting a silver halide photographic light-sensitive material for the purpose of obtaining a dye of a certain density, the molar concentration of the coupler must be increased or the amount of silver used must be increased. . This means an increase in the manufacturing cost of silver halide color photographic materials. Further, it has been found that certain unreacted residual couplers have drawbacks such as poor storage stability of the produced dye. Many proposals have been made to improve the color development properties of these couplers. One such proposal is the use of 2-equivalent couplers, i.e., couplers that require only two exposed silver halide molecules to obtain one molecule of dye;

It is described in No. 50-28834, No. 56-153343, No. 51-102636, etc. Another proposal is to use a coupler with a hydrophilic group introduced therein, such as JP-A-50-87650 and JP-A-54-54.

54-48541 etc. However, the couplers obtained by these methods still had insufficient coloring performance. For this reason, the current practice is generally to add benzyl alcohol to obtain sufficient color development. However, from the standpoint of depollution, the removal of benzyl alcohol added to color developing solutions has been taken up as a major problem. Removal of benzyl alcohol greatly reduces color development in yellow couplers, and from this point of view as well, there is a desire for a yellow coupler that exhibits high color development even without benzyl alcohol. [Object of the Invention] The first object of the present invention is to provide a silver halide color photographic light-sensitive material that provides a yellow dye image with high sensitivity and high color density. A second object of the present invention is to provide a silver halide color photographic material that provides a yellow dye image that does not cause a decrease in color development even when processed with a color developer from which benzyl alcohol has been removed. A third object of the present invention is to provide a silver halide color photographic material that provides a yellow dye image with less unreacted residual coupler. A fourth object of the present invention is that it can be manufactured relatively inexpensively,
Another object of the present invention is to provide a silver halide color photographic material that provides a yellow dye image that can save silver.
