RADIOGRAPHIC ORTHOCHROMATIC HALOGENSILVER FILM FOR X-IMAGES AMPLIFIERS

摘要

The solution concerns an orthochromatically super sensitized radiographic halogen-silver photographic material with maximum of spectral sensitization of 550 to 580 nm with sensitization range of 590 to 600 nm, whose base is formed by bromide-iodide-silver emulsion with different shape and size of emulsion microcrystals containing from 1.5 to 8 mol percent of AgJ and from 92 to 98.5 mol percent of AgBr in solid phase, which is spectrally sensitized by combination of imidacarbocyanines variably substituted on nitrogen atoms and on benzene cores in positions 5 and 6.
