Abstract
A film is disclosed for duplicating a silver image in a radiographic film. A single monodispersed fogged direct-positive emulsion layer is employed. To extend exposure latitude the emulsion layer contains micro-crystalline particles of a dye that competes with the fogged direct positive grains of the emulsion layer for absorption of exposing radiation and can be decolorized during photographic processing.
