Procedure

In 3000 ml of water were dissolved 28 g of gelatin and 13.2 g of benzotriazole, and the solution was kept at 40° C. under stirring. A solution of 17 g of silver nitrate in 100 ml of water was added to the above solution over a period of 2 minutes. The excess salt was sedimented and removed by pH adjustment. The emulsion was then adjusted to a pH of 6.30 to obtain 400 g of a silver benzotriazole emulsion.
