FIELD: chemical photographic industry and industrial radiography, additional treatment of halogensilver photographic materials. SUBSTANCE: to increase photographic sensitivity of halogensilver material they use method of production of brown nickel-bearing nonsilver photographic image on radiographic film, that provides for bleaching in solution, that has nickel chloride (II), trisubstituted sodium citrate, potassium hexocyanoferrate (III) and water, fixation in 25 % water solution of sodium thiosulfate, toning in water solution, that has (g/l): dithiooxamide (15.0 - 25.0), formaldehyde (7.0 - 15.0), potassium hydroxide (10.0 - 15.0),. Toning stage is realized for 6 - 10 minutes under temperature of 18 - 20 C. Method allows to increase photographic sensitivity by 1.5 - 2 times. EFFECT: increased photographic sensitivity. 1 tbl |
