Procedure

6.5 g of benzotriazole and 10 g of gelatin were dissolved in 1,000 ml of water and the solution was stirred while maintaining at 50° C. A solution containing 8.5 g of silver nitrate dissolved in 100 ml of water was added to the above described solution for a period of 2 minutes. By controlling the pH of the emulsion thus prepared to form a precipitate the undesirable salts were removed. The pH of the emulsion was adjusted to 6.0 and 400 g of silver benzotriazole emulsion was obtained.
