Abstract

1413826 Sensitizing silver halide emulsions FUJI PHOTO FILM CO Ltd 27 Oct 1972 [28 Oct 1971] 49776/72 Heading G2C A negative working photographic light-sensitive emulsion contains (a) silver bromoiodiode grains dispersed in a hydrophilic binder comprising more than 50% by weight of gelatine, (b) at least one cyanine dye (the term cyanine dye including monemethaine cyanine and carbocyanine dyes, but excluding merocyanine dyes which sensitizes the emulsion to the green region of the spectrum and (c) at least 0.01 mole of iodide ions per 100 moles of silver halide adsorbed on the silver bromiodide grains. The iodide is preferably in the form of a water soluble iodide e.g. KI, NaI, NH 4 I, ZnI 2 , CoI 2 , CdI 2 , CaI 2 , SrI 2 , and BaI 2 , and bromide ions may also be present. The dye is preferably an oxacarbocyanine, benzimidazolocarbocyanine, benzimidazoloxa carbocyanine or benzimidazoloindocarbocyanine.
