Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a silver halide photographic material containing a novel IR coupler capable of reacting with an oxidized form of a developing agent and releasing a development inhibitor.

[Prior Art] In recent years, there has been a strong desire to develop color photosensitive materials that are highly sensitive and have excellent sharpness and color reproducibility.

As a means of improving sharpness, it is known to use DIR compounds that react with oxidized forms of color developing agents to release development inhibitors. It is well known that by including this in an emulsion, the sharpness of the color image is enhanced due to the edge effect, and furthermore, color reproduction is improved due to the multilayer effect. However, these DIR compounds have the disadvantage that the development inhibitor released during color development diffuses into the processing solution from the light-sensitive material and accumulates, resulting in the processing solution exhibiting development inhibiting properties.

In order to solve such problems, Japanese Patent Application Laid-Open No. 57-151

No. 44, No. 60-221750, No. 61-11743
The method described in US Pat. No. 4,782,012 has been proposed. In these methods, a coupler is used which exhibits development inhibiting properties when released from the coupling position of the coupler, and which decomposes into compounds that do not affect photographic properties after flowing out into the processing solution. It is being

It is true that with this coupler, even when Taisho photosensitive feed was subjected to running processing, there was little decrease in sensitivity and contamination of the developer was considerably reduced.

[Problems to be Solved by the Invention] However, the photosensitive feed containing the above-mentioned coupler has an increase in fog during storage and deterioration in sensitivity, sharpness, and color reproduction, and also has the performance of the coupler itself, such as edge effect, Considering the coexistence of the multilayer effect, this is still not sufficient.

An object of the present invention is to provide a color photosensitive feed that has good image sharpness and color reproducibility, and also has improved storage stability over time.
