However, the spectral sensitivity distribution is not always satisfactory due to constraints on the structure of the sensitizing dye or the state of adsorption on the silver halide grains. Therefore, there is a method of correcting the spectral sensitivity distribution using photographic dyes, but photographic dyes themselves reduce sensitivity and have a desensitizing effect, are difficult to fix in specific layers, and leave behind color after image formation. There are problems such as. In particular, it often inhibits the spectral sensitization effect of silver halide emulsions by sensitizing dyes. Improvements have also been made in methods of fixing these dyes to specific layers.

For example, U.S. Pat. No. 3,247,127, U.S. Pat.

However, applying these fixing methods to color photosensitive materials with a multilayer structure has many manufacturing difficulties and has not yet been practically put into practical use.Compared to black and white photosensitive materials, color photosensitive materials have at least Since silver halide emulsion layers having different species, spectral sensitivity distributions, and couplers are independently provided on a support, the above defects are a particular problem.

Colored couplers are used as dyes (for example, Japanese Patent Application No. 59-1
77670, U.S. Pat. No. 4,234,672, U.S. Pat. No. 43
No. 10612, No. 3579334, No. 39999
There is also a method using compounds described in No. 91, No. 3994731, and No. 3230085. However, it is difficult to remove residual color from colored couplers. Further, in order to release the dye portion, it is necessary to coexist with developable silver halide or the like. For this reason NW.

This results in defects such as increased thickness and increased color mixture.

(Purpose of the invention) The object of the present invention is to remedy these deficiencies.

In other words, the first purpose is to improve the spectral sensitivity distribution by dyeing a specific layer, and also to effectively prevent halation or irradiation to improve the color reproducibility and sharpness of the original image. It is in the provision of materials. Second
The purpose of this invention is to provide a color photosensitive material which is devised so that the dye used to dye a specific layer during the color development process is decomposed and released so that there is no residual color. Other objects will be apparent from the description.

Means for Solving the Problems The object of the present invention is to provide silver halide emulsion layers, each containing at least one yellow coupler, on a Tll support.

H (25°C) 4.0 The results are shown in Table 1. Compared to the comparative example, the sample of the present invention had less color mixing of magenta with yellow and green, and an improvement in color purity was observed.

This allows us to distinguish between orange yellow and lemon yellow, j! '# The reproduction of green color was improved, and a level of improvement that could not be achieved conventionally by adjusting the spectral sensitivity distribution by selective use of sensitizing dyes was obtained.

This is because the compound of the present invention moves less between the eyebrows than the water-soluble dyes commonly used, resulting in a higher filtering effect.
This is thought to be due to improved color separation as a result. Furthermore, since the compound of the present invention has high hydrophobicity, there is little (low) decrease in sensitivity.

In the sample of the present invention, the sensitivity of the green sensitive layer is high, and the Dmin of the yellow color image is low. This is probably because the compound of the present invention has better absorption on the long wavelength side than colloidal silver, and also has better decolorizing properties during development than Compound A, resulting in less residual color.
