Reaction Conditions

Reaction Steps

Using an apparatus shown in FIG. 5, particulate organic silver salt 4-1 was prepared in the following manner. Into a tank (31) containing 5.7 g of behenic acid and 650 g of pure water with stirring at 85° C., 10.0 ml of 1.5N aqueous KOH solution was added in 5 min. and reacted further for 60 min. to obtain a potassium behenate solution. Finally, water was added to make the total amount to 750 ml. To a tank (32), 750 ml of aqueous solution containing 2.6 g of silver nitrate was added and maintained at 10° C. To the mixing device (33) in which a supply tube and a discharge tube, each had an inside diameter of 4 mm, the foregoing potassium behenate solution and aqueous silver nitrate solution were supplied at a flow rate of 1500 ml/min to perform nucleation. The silver content of the organic silver salt particles was 0.01 mol/l/.
