METHOD OF PREPARATION FOR CASTING OF BROMINE-IODINE-SILVER PHOTOGRAPHIC EMULSION FOR BLACK-AND-WHILE CINEPHOTOMATERIALS Russian patent published in 1995 - IPC

Abstract RU 2030776 C1

FIELD: manufacture of cinephotomaterials. SUBSTANCE: for production of photolayer of high sensitivity especially behind light filters OC-14 and KC-14 method of preparation for casting of black-and-white cinephotomaterials provides for injection of three sensitizers - thicarabocianine pigments in the amount of 10-6 M/M AgHa each into melted emulsion. After each sensitizer accelerator of spectral sensitization - salt of benzimidazolium of following formula (image) is injected. EFFECT: facilitated manufacture. 1 tbl
