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.
