실험 절차

In 3,000 ml of water were dissolved 28 g of gelatin and 13.2 g of benzotriazole, and the solution was kept at 40° C. while stirring. To the solution was added 100 ml of an aqueous solution containing 17 g of silver nitrate over 2 minutes. Excess salts were sedimented and removed from the resulting emulsion by pH adjustment. Thereafter, the emulsion was adjusted to a pH of 6.30 to obtain a silver benzotriazole emulsion. The yield of the emulsion was 400 g.
