Abstract

1,177,141. Spectrally sensitizing silver halides. EASTMAN KODAK CO. March 7, 1967 [March 8, 1966], No. 10613/67. Heading G2C. Silver halide emulsions are spectrally sensitized by forming an aqueous solution of a photographic spectral sensitizing dye having the amidinium ion auxochromophore e.g. a cyanine or hemicyanine wherein the dye is present in protonated form and subsequently contacting the aqueous solution with the emulsion or dispersing it is a hydrophilic colloid and adding it to the emulsion. The pH of the hydrophilic colloid and the emulsion being regulated such that the dye is converted to its unprotonated form.
