Reaction Conditions

Reaction Steps

11.3 g of 5-amino-3-benzylthiotriazole, 1.1 g of sodium hydroxide and 10 g of gelatin were dissolved in 1000 L of water, and the solution was maintained at 50° C. under agitation. Subsequently, a solution obtained by dissolving 8.5 g of silver nitrate in 100 mL of water was added to the above solution over a period of 2 min. The pH of the mixture was regulated so as to precipitate an emulsion, and excess salts were removed. Thereafter, the pH was adjusted to 6.0. Thus, a 5-amino-3-benzylthiotriazole silver salt emulsion was obtained with a yield of 400 g.
