Vorschrift

A solution of 8.6 g of capric acid in 100 ml of butyl acetate was maintained at a temperature of 5° C., to which 200 ml of water was added with stirring to form an emulsion. 50 ml of an aqueous solution of silver ammonium complex containing 8.5 g of silver nitrate (chillset at 5° C.) was added to the above emulsion over a 30 second period in order to allow the capric acid to react with the silver ion. After the removal of an aqueous phase, a silver caprate-containing butyl acetate phase was dispersed into 120 g of isopropanol solution containing 15 weight percent of polyvinyl butyral to produce a polymer dispersion of silver caprate. A composition containing the several components setforth below were added to the polymer dispersion of silver caprate in their listed order every ten minutes while maintaining the temperature at 50° C., resulting in the formation of a heat developable light-sensitive coating composition.
