Abstract

1,139,062. Emulsions containing dyes to prevent image spread. KODAK Ltd. March 11, 1966 [Jan. 1, 1965], No.38/65. Heading G2C. A sensitive photographic material comprises a silver halide emulsion wherein the silver halide has an average grain diameter of 0À1Á or less and the weight ratio of silver halide to binder is 2:1, the layer containing a dye which is water soluble or bleachable during processing which absorbs light of the composition selected for exposing the emulsion layer, the concentration of the dye being great enough to give the layer an optical density of at least 0.15 per micron thickness of said layer to light of the selected composition. A specified dye is bis(3-methyl-1- p-sulphophenyl-4-pyrazol-5-one)-trimethinoxonol.
