PHOTOSENSITIVE SILVER HALIDE EMULSION AND HEAT DEVELOPABLE PHOTOSENSITIVE MATERIAL

摘要

PROBLEM TO BE SOLVED: To provide a high sensitivity photosensitive silver halide emulsion using high silver iodide and a high sensitivity heat developable photosensitive material. SOLUTION: The photosensitive silver halide emulsion comprises silver halide emulsion grains, wherein≥50% of the total projected area of the silver halide emulsion grains is occupied by silver halide emulsion grains (1) containing a transition metal complex containing at least one carbonyl ligand and (2) having an averageβphase ratio of≥1 mol%.
