Procedure

200 ml. of toluene in which 12 g. of lauric acid was dissolved was mixed with 100 ml. of an aqueous solution containing 1.9 g. of sodium hydroxide, and then emulsified by means of a homomixer. To the emulsion, 50 ml. of 0.4% aqueous solution of hydrobromic acid was added and emulsified. To the emulsion, 50 ml. of an aqueous solution containing 8.5 g. of silver nitrate was added to produce silver laurate and silver bromide, simultaneously. After removing the water layer, the toluene layer was dispersed in 120 g. of a 15% isopropanol solution of polyvinyl butyral to obtain a dispersion (hereinafter, referred to "silver salt polymer dispersion").
