METHOD OF PREPARING SILVER BROMID-IODIDE PHOTOGRAPHIC EMULSIONS FOR RED SENSITIVE LAYER OF COLOR PHOTOGRAPHIC MATERIAL FOR COATING Russian patent published in 1994 - IPC

Abstract RU 2007746 C1

FIELD: producing color cine- and photomaterials. SUBSTANCE: method of preparing silver bromid-iodide photographic emulsions with content of AgO of 0.5-5.1 mol. % with pBr of 2.7-3.1 and pH of 5.75-6.7 for coating involves the steps of introducing a stabilizer, antioxidant, sensitizer, dispersion of blue color forming component and copolymer-N-vinyl α pyrrolidone with methylmethacrylate in amounts of 0.15-1.5 g/kg of emulsion. EFFECT: reduced fog optical density level with maintaining photosensitivity level constant and maximum blue image density.
