Abstract

PURPOSE: To prevent deterioration in the stable-image forming properties and the light attenuating speed characteristics due to heat, etc. by heating a dispersion contg. cadmium sulfide particles and a sulfur forming substance under pressure to stabilize the surfaces of the cadmium sulfide particles.
CONSTITUTION: Sodium thiosulfate or the like forming sulfur by heating is added to an aqueous dispersion of cadmium sulfide, and this dispersion is heated under pressure in an autoclave or the like to cause reaction. The reaction product is allowed to cool, washed, and freed of ions remaining on the surfaces of the cadmium sulfide particles with an ion exchange resin or the like. It is then dehydrated and dried. By selecting the reaction conditions, cadmium sulfide powder having stable surface and superior moisture resistance is obtd.
