Embodiment 1

[0375] An ethylene terephthalate film support (having a thickness of 120 micrometers) was prepared by applying the coating to an ethylene terephthalate film such that the surface coated with the emulsion was covered with a substrate. The coating was applied and the surface opposite to the emulsion-coated surface was coated with a conductive polymer containing the following (0.05 g / m 2 ) and tin oxide (0.20g / m 2 ) of the acrylic layer.

[0379] The methanol-wet filter cake of the exemplary dye (IV-1) was used in an amount equivalent to 240 g wet weight of the exemplary compound (V-12) as a dispersing aid, and the amount of water was such that the total The amount reaches 4000 grams. These materials were loaded with 1.7 liters of zirconia beads (0.5 mm in diameter) into a "jet mill (UVM-2)" (manufactured by Imex Co. / sec peripheral speed grinding for 2 hours. The resulting dispersion product was diluted with water so that ...

Embodiment 2

[0574] Emulsions were prepared according to the procedure of Example 1 except that only the halogen composition was changed to Cl / Br = 99.5 / 0.5 at the grain formation of silver halide emulsions R1 and G1 for the fourth and sixth layers. These emulsions were blended with sensitizing dyes in amounts equal to emulsions R1 and G1 and chemically aged to an optimized degree by adding sulfur sensitizers and gold sensitizers. Samples 201-227 were prepared by substituting these emulsions for emulsions R1 and G1 of samples 102-127. Samples 201 to 227 were subjected to the same treatment as in Example 1 and were subjected to the same evaluation. The same evaluation results were obtained. Accordingly, it can be seen that the present invention is effective in a silver halide photographic photosensitive material using a silver halide emulsion having a higher silver chloride content.

Embodiment 3

[0576] The conditions and formulations of the processing solution used in the developing step in the processing of Example 1 were changed as follows. Also, the 6th and 7th steps (that is, the first fixing step and the subsequent water washing step) are omitted. The color tone and color density of the samples 201 to 227 prepared in Example 2 were evaluated by using the above conditions and the rinse solution. Also, in order to verify whether the unnecessary dye was completely removed, the cyan density in the unexposed area after processing was measured. The less dense the cyan, the more adaptable the material is to rapid washdown. The results are shown in Table 11.

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...
