SILVER BROM(OIOD)IDE EMULSIONS OF INCREASED SENSITIVITY IN THE NEAR INFRARED

摘要

SILVER BROM(OIOD)IDE EMULSIONS OF INCREASED SENSITIVITY IN THE NEAR INFRARED A photographic emulsion is disclosed in which an infrared spectral sensitizing dye is adsorbed to the surface of silver bromide grains optionally containing iodide. The grains are formed in the presence of a hexacoordination complex of iron and at least three cyanide ligands to counteract dye desensitization.
