PRODUCTION OF ORGANIC SILVER DISPERSION AND HEAT DEVELOPABLE PHOTOSENSITIVE MATERIAL

摘要

PROBLEM TO BE SOLVED: To obtain an organic silver dispersion improved in dispersibility of an organic silver salt by cooling a raw material solution containing an organic silver salt and dispersing the organic silver salt and obtain a heat developable photosensitive material reduced in fogging by using the organic silver dispersion. SOLUTION: In this method for producing an organic silver dispersion by applying >=580 kgf/cm2 pressure to a raw material solution comprising at least organic silver salt and a solvent, when the temperature before disperse of the raw material solution is controlled to -95 deg.C to 35 deg.C and the pressure is A kgf/cm2 and the temperature before disperse of the raw material solution is B deg.C, the following formula is satisfied: 50>2A/100+B.
