METHOD OF SPECTRAL SENSITIZATION OF SILVER BROMOIODINE PHOTOEMULSIONS Russian patent published in 1995 - IPC

Abstract RU 2040030 C1

FIELD: chemical-photographic industry. SUBSTANCE: this method of spectral sensitization of silver bromoiodine photo emulsions prescribes introducing two thiacarbocyanine dyes, that is, 3,3′-di-γ-sulfopropylate thiacarbocyanine salts and one oxacarbocyanine dye into emulsion. EFFECT: higher photosensitivity and uniformity of sensitivity to green and red spectral zones. 4 tbl
