Procedure

In 3,000 ml of water were dissolved 28 g of gelatin and 13.2 g of benzotriazole. While stirring the solution at 40° C., a solution of 17 g of silver nitrate dissolved in 100 ml of water was added to the solution for a period of 2 minutes. Then, by adjusting the pH of the emulsion thus obtained, the excess salts were precipitated and removed. Thereafter, the pH of the emulsion was further adjusted to 6.30 to provide a benzotriazole silver emulsion. The amount of the emulsion obtained was 400 g.
