Reaction Steps

In 1,000 ml of water were dissolved 10 g of gelatin and 6.5 g of benzotriazole and then the solution was stirred at 50° C. A solution of 8.5 g of silver nitrate dissolved in 100 ml of water was added to the foregoing solution over a period of 2 minutes and further a solution of 1.2 g of potassium bromide dissolved in 50 ml of water was added thereto over a period of 2 minutes. By adjsuting the pH of the emulsion thus prepared, excessive salts were precipitated and after removing the salts thus precipitated, the pH of the emulsion was adjusted to 6.0 to provide 200 g of a silver benzotriazole emulsion containing silver bromide.
