SILVER HALIDE PHOTOSENSITIVE MATERIAL, SILVER HALIDE PHOTOSENSITIVE MATERIAL FOR FORMATION OF MONOCHROMATIC IMAGE, PHOTOGRAPHIC UNIT AND FORMING METHOD OF MONOCHROMATIC IMAGE

摘要

PROBLEM TO BE SOLVED: To obtain a photosensitive material which is adaptable for negative-positive color photographic developing processes, has excellent graininess and process stability and makes easy to print on a printing sheet, especially easy to produce a sepia-tone monochromatic print by incorporating couplers of six equiv. ;SOLUTION: The photosensitive material contains couplers of six equiv. These couplers of six equiv. are a yellow coupler of two equiv., a magenta coupler of two equiv., and a cyan coupler of two equiv., and all couplers are included in the same oil-drops. The photosensitive layer contains a silver halide emulsion which is panchromatically sensitized and a dispersion material of the couplers of six equiv. This silver halide contains planer silver halide particles of AgBrI having ≥3 average aspect ratio. Thereby, the obtd. material is adaptable for negative-positive color photographic developing processes, has excellent graininess and process stability and can be easily printed on a printing sheet, and especially, with the obtd. material, a sepia tone monochromatic print can be easily produced.;COPYRIGHT: (C)1997,JPO
