Abstract
1297901 Photographic silver halide emulsions FUJI PHOTO FILM Co Ltd 1 Jan 1970 [7 March 1969] 43/70 Heading G2C The sensitivity of a photographic silver halide emulsion in which at least 95 per cent of the silver halide grains are of a size less than 02 microns, or the mean grain size of the silver halide grains is less than 0À18 microns, is increased in the intrinsic absorption wavelengths of the silver halide by adding thereto a dye having an oxidation potential of less than 0À90 volt. When the dye is an optical sensitizing dye, the sensitivity is also increased in the optical sensitization wavelength region. Dyes specified for use are cyanines, merocyanines, hemicyanines, rhodacyanines, trinuclear cyanines and styryl dyes. The emulsion may also be chemically sensitized.
