Radiographic element exhibiting reduced crossover
This patent describes a radiographic element comprised of a film support capable of transmitting radiation to which the radiographic element is responsive having opposed major faces; processing solution permeable hydrophilic colloid layers including, coated on each opposed major face, at least one silver halide emulsion layer capable of responding to electromagnetic radiation in the visible portion of spectrum and at least one other hydrophilic colloid layer, interposed between the emulsion layer and the support; and a dye dispersed in at least one of the interposed hydrophilic colloid layers capable of absorbing visible radiation to which the radiographic element is responsive to reduce crossover and being decolorized in a processing solution. Prior to processing, the dye is in the form of microcrystalline particles present in a concentration sufficient to reduce crossover to less than 10 percent and is capable of being substantially decolorized in less than 90 seconds during processing.
