Abstract

The present invention provides a silver halide color photographic photosensitive material having superior image sharpness and film strength, in which a yellow-developing photosensitive silver halide emulsion layer on a support contains at least one dye-forming coupler represented by the following general formula (Y-1), and at least one layer of the non-photosensitive hydrophilic colloid layers on the support contains a dispersion of solid particles of a dye represented by the following general formula [I]. In the general formula (Y-1), Y represents a nitrogen-containing heterocycle; Z represents a substituted aryl group; X represents a hydrogen atom, or a group that leaves by the reaction with an oxidized form of a developing solution. In the general formula [I], D represents a residue of a compound having a chromophoric group; X represents a dissociative hydrogen atom or a group having a dissociative hydrogen atom,y is an integer which is from 1 to 7. General formula (Y-1), General formula (I).

Description

technical field

[0001] The present invention relates to a silver halide color photographic photosensitive material having improved color reproducibility and processing stability, and more particularly, to a silver halide color photographic photosensitive material having these properties and being useful for cinematography. Background technique

[0002] There has been a need to improve the image quality of silver halide color photographic photosensitive materials for viewing, recording and preserving images, and therefore many studies have been conducted. Examples of methods of improving the image quality of silver halide color photographic photosensitive materials include the following methods.

[0003] (1) Improving the clarity of images by methods such as using radiation-resistant dyes, reducing the thickness of the hydrophilic colloid layer coated on the support, and forming a colored layer for preventing halation;

[0004] (2) Improved granularity by reducing the size o...
