Procedure

Gelatin (which had received an ion exchange treatment) in the amount of 73 g was added to 1,000 ml of water and dissolved therein by heating at 50° C. Thereto was added 31 g of behenic acid, and it was heated at 90° C. to dissolve the behenic acid therein. Further, the resulting solution was admixed with 39 ml of 1N NaOH and 2 g of NaCO2, and stirred for 4 minutes at 12,000 r.p.m. by means of a homogenizer. Thus, a monodisperse fine grain dispersion of behenic acid/sodium behenate mixture was obtained. The dispersion thus obtained was heated to 50° C., adjusted to pH 7 with HNO3, and then admixed with 0.1 g of N-bromosuccinimide. Thereto was added a solution of 12 g of silver nitrate in 47 ml of water over a 5-minute period with stirring at 1,200 r.p.m. After cooling down to 35° C., the resulting reaction mixture was subjected to a desalting treatment with a flocculant, admixed with gelatin (which had undergone an ion exchange treatment) and then adjusted to pH 6 with NaOH. Thus, an intended silver behenate Dispersion A was prepared.
