ABSTRACT:
Direct X-ray films are disclosed capable of being handled in room light prior to and during processing. The films contain silver halide grains responsive to X-radiation that are sulfur sensitized. The films also contain a combination of processing solution bleachable dyes chosen to provide prior to processing (a) an average density of greater than 3.0 over a first, continuous spectral sensitivity range extending from a minimum wavlength of 320 nm over which the silver halide grains exhibit an absorption coefficient of at least 0.5 cm.sup.-1 and (b) a density of greater than 3.0 throughout a second spectral range including wavelengths of from 600 to 650 nm.
