Zusammenfassung:	A direct X-ray dental film is disclosed that, following imagewise exposure, can be removed from its opaque package and processed in room light. The film is comprised of emulsion and protective layers that contain dye particles which can be decolorized during processing. The dye particles provide an average density of greater than 3.0 over a spectral range of above 320 nm over which the silver halide exhibits an absorption coefficient of at least 0.5 cm. For additional protection the emulsion layers contain desensitizer adsorbed to the silver halide grains to reduce their sensitivity to light without significantly reducing their sensitivity to X-radiation.
