Vorschrift

In 3,000 ml of water were dissolved 28 g of gelatin and 13.2 g of benzotriazole, and the solution was stirred while maintaining at 40° C. A solution of 17 g of silver nitrate in 100 ml of water was added thereto over 2 minutes. An excess of salts was precipitated by pH adjustment and removed. The dispersion was then adjusted to a pH of 6.3 to obtain 400 g of a silver benzotriazole emulsion.
