Procedure
0.34 g of benzotriazole, 0.24 g of sodium hydroxide, and 25 g of phthalated gelatin were dissolved in 700 mL of water. The solution was kept at 60° C. and stirred. Then, to the solution, were added a solution prepared by dissolving 3.4 g of benzotriazole and 1.2 g of sodium hydroxide in 150 mL of water, and a solution prepared by dissolving 5 g of silver nitrate in 150 mL of water, simultaneously, near a stirrer, over a period of time of 4 minutes. The resulting solution was stirred for 5 minutes. After that, to the solution were added a solution prepared by dissolving 3.4 g of benzotriazole and 1.2 g of sodium hydroxide in 150 mL of water, and a solution prepared by dissolving 5 g of silver nitrate in 150 mL of water, simultaneously, near the stirrer, over a period of time of 6 minutes. The pH of the resulting emulsion was adjusted so as to cause precipitation, and excess salt was removed. After that, the pH was adjusted to 6.0, and a silver benzotriazole emulsion in an yield of 470 g was obtained.
