Procedure

One liter of an aqueous solution of 20 g of sodium hydroxide was mixed with 2 liters of toluene having dissolved therein 120 g of lauric acid, and the mixture was emulsified using a high speed rotary stirrer. To the emulsion, 500 ml of a 0.4% by weight aqueous solution of hydrobromic acid was added, and the mixture was again emulsified. To the resulting emulsion, 500 ml of an aqueous solution of 85 g of silver nitrate was added to form silver laurate and silver bromide simultaneously. The toluene phase containing the silver nitrate and the silver bromide was separated from the aqueous phase, and dispersed in 2.4 Kg of a 15% by weight isopropanol solution of polyvinyl butyral using a high speed rotary stirrer.
