ABSTRACT:
A reflective radiographic material (at least 200 system speed) is useful especially to provide images that can be viewed without a light box. This reflective radiographic material has a reflective support, a silver halide emulsion on one side of the support only, and a photographic speed of at least 200. The reflective material also includes an incorporated black-and-white developing agent and a co-developing agent, and can be used with a single fluorescent intensifying screen as part of an imaging assembly. The reflective support enables viewing the resulting image without a light box and the high speed of the material enables the use of low power X-radiation generating equipment. The incorporated black-and-white developing agent and co-developing agent allow the radiographic material to be quickly processed after exposure using simplified processing chemistry.
