Procedure

11 g of lauric acid was dissolved in 100 ml of butyl acetate and the resulting solution was kept at 10° C. To the solution were added with stirring by means of a stirrer 100 ml of a dilute aqueous solution of nitric acid (25° C, pH = 2.0) and 50 ml of an aqueous solution of silver ammonium complex salt containing 8.5 g of silver nitrate (cooled to 0° C) for 1 minute, thus reacting the lauric acid and the silver ion and obtaining spindle-shaped silver laurate crystals having a length of about 1 micron and width of about 0.05 micron. After washing this silver salt with water and further with methanol, 3.0 g of polyvinyl butyral and 20 ml of isopropyl alcohol were added to 2.7 g of the silver laurate and dispersed in a ball mill to prepare a silver salt polymer dispersion.
