Procedure

1.9 g of sodium hydroxide was dissolved in 200 ml of water. To this solution, a solution produced by dissolving 12 g of lauric acid in 100 ml of toluene was added and the mixture was stirred with a stirrer to emulsify. To this emulsion, an aqueous solution of silver nitrate (silver nitrate: 8.5 g, water: 50 cc) was added over a 60 second period to produce silver laurate while stirring (800 rpm, 5 minutes). The precipitated silver laurate was removed and dispersed using a ball mill in 30 mg of polyvinyl butyral and 200 ml of isopropyl alcohol to produce a polymer dispersion. This was designated Solution A. 6 cc of a 1.4% methanol solution of N-bromophthalazinone was added to 50 g of the above described polymer dispersion of the silver salt and the mixture was stirred at 50° C. for 90 minutes. This was designated Solution B. To 25 g of Solution B, materials of the following Composition (I) were added to produce a heat-developable photosensitive composition. This composition was applied to a paper support (art paper) at a coverage of 0.4 g of silver per m2 of the support to produce a heat-developable Photosensitive Material (B - 1).
