Procedure
To a tank (34) containing 1000 ml of pure water kept at 30° C., the foregoing nucleus particles were continuously introduced. Into a tank (35) containing 218.7 g of behenic acid and 4155.3 g of pure water with stirring at 85° C., 387.3 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 5250 ml. To a tank (36), 1050 ml of aqueous solution containing 98.7 g of silver nitrate was added and maintained at 10° C. Further, 525 ml of an aqueous solution containing 43 g of light-sensitive silver halide emulsion A was prepared in a tank (37) and maintained at 30° C. The foregoing potassium behenate solution, aqueous silver nitrate solution and silver halide solution were added by triple jet addition at flow rates of 150 ml/min. 30 ml/min and 15 ml/min, respectively to perform particle growth.
