Abstract

1,150,013. Emulsions making. FUJI SHASHIN FILM K. K. Sept. 16, 1966 [Sept. 22, 1965], No. 41435/66. Heading G2C. Photographic silver halide emulsions are obtained by preparing a silver iodide suspension containing a protective colloid and an amount of silver ions in excess over those required to form the silver iodide and adding said silver iodide suspension to an aqueous solution containing a bromide in an amount in excess of that required to precipitate the excess silver ions in said suspension to form a silver iodo-bromide emulsion. The protective colloid may be gelatine (active or inactive), polyvinylalcohol, a polyvinyl lactam or polyacrylamide. The emulsion may be chemically sensitized with sodium thiosulphate, auric chloride, aurochlouric acid and potassium isothiocyanate and may contain 4-hydroxy-6- methyl-1, 3, 3a, 7-tetra-azaindene as stabilizer.
