METHOD OF CHEMICAL-PHOTOGRAPHIC TREATMENT OF HALOGEN-SILVER PHOTOGRAPHIC MATERIALS Russian patent published in 1995 - IPC

Abstract SU 1342285 A1

FIELD: photography. SUBSTANCE: photographic material consists of the backing and gelatinous emulsion layer containing silver bromide which is grown as envelope on calcium fluoride nuclei. Treatment involves development and fixing. Additional treatment is carried out in solution containing aluminium salt: aluminium chloride, aluminium-potassium sulfate, aluminium-ammonium sulfate, and water. Solution composition, g/l: aluminium salt 30-400; ammonium acetate 20-200, water up to 1 l. Method improves decrease optical density background from 0.34 to 0.01. EFFECT: decreased optical density of background, accelerated process. 2 cl, 2 tbl
