Procedure

28 g of gelatin and 13.2 g of benzotriazole were dissolved in 300 ml of water, and the solution was stirred while maintaining the temperature at 40° C. A solution containing 17 g of silver nitrate dissolved in 100 ml of water was added to the above solution over a 2 minute period. By controlling the pH of the silver iodogromide emulsion, precipitates were formed and exess salts were removed. The pH of the emulsion was then adjusted to 6.0 and 400 g of a benzotriazole silver salt emulsion was obtained.
