Procedure
Prepared by mixing simultaneously an ammoniacal silver nitrate aqueous solution and bendotriazole (containing 0.2 mol % of aqueous ammonia per mol benzotriazole) into a 10%-aqueous solution of phenylcarbamoyl gelatin of 50° C. After completing the addition, the pH was reduced and then flocculation and desalting were carried out to obtain needle crystals (width: 0.1 to 0.2 μm, length: 0.5 to 2 μm). ##STR9##
