PHOTOSENSITIVE SILVER HALIDE EMULSION, HEAT DEVELOPABLE PHOTOSENSITIVE MATERIAL AND METHOD FOR MANUFACTURING THE SAME

摘要

PROBLEM TO BE SOLVED: To obtain a heat developable photosensitive material having low fog, high sensitivity, high maximum density and excellent moisture resistance, and to provide a photosensitive silver halide emulsion for the same. SOLUTION: The photosensitive silver halide emulsion uses modified gelatin soluble in both water and an organic solvent as a dispersant. An average grain diameter of silver halide grains contained in the photosensitive silver halide emulsion is 0.005-0.1μm and a variation coefficient of grain size is 0-30%. COPYRIGHT: (C)2006,JPO&NCIPI
