摘要： Black-and-white elements, such as radiographic films, can be processed in roomlight because they include certain light absorbing dyes and desensitizers. Processing is carried out by processing the exposed element using a two-stage process in the same light-tight processing container. In the first stage, development is initiated with a developing composition having a pH of from about 10 to about 12.5, and comprising an appropriate black-and-white developing agent in a concentration of from about 0.1 to about 0.5 mol/l, and a sulfite at from about 0.25 to about 0.7 mol/l. After an appropriate time, a fixing agent (other than a sulfite) is introduced into the processing container to provide a combined developing/fixing compositions, and development and fixing are carried out simultaneously. The processing method is carried out quickly, usually within about 90 seconds, including a washing step at the end. The presence of sulfite and high pH in both stages decolorize or deactivate the particulate dyes.

摘要： 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.

摘要： 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.sup.-1. 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.

摘要： Black-and-white elements, such as radiographic films, can be processed in roomlight because they include certain light absorbing dyes and desensitizers. Processing of such elements can be achieved using a processing kit and a two-stage process carried out in the same light- and fluid-tight processing apparatus. In the first stage, development is initiated with a developing composition having a pH of from about 10 to about 12.5, and comprising an appropriate black-and-white developing agent and a sulfite. After an appropriate time, a non-sulfite fixing agent is introduced into the processing apparatus or container to provide a combined developing/fixing composition, and development and fixing are carried out simultaneously. The processing method is carried out quickly, usually within about 90 seconds. The presence of sulfite and high pH in both stages decolorizes or deactivates the particulate dyes. The processing kit includes the photographic element, a first vessel containing a developing composition, a second vessel containing a fixing composition, and a container for holding an exposed element. The first and second vessels have manually actuated dispensers for dispensing developing composition and fixing composition into the container for processing of the exposed element.

摘要： Black-and-white elements, such as radiographic films, can be processed in roomlight because the developing composition includes a particulate opacifying agent, such as carbon black. Processing is carried out by processing the exposed element using a two-stage process in the same processing container. In the first stage, development is initiated with an opaque developing composition having a pH of from about 10 to about 12.5, and comprising an appropriate black-and-white developing agent in a concentration of from about 0.1 to about 0.5 mol/l, opacifying agent, and a sulfite at from about 0.1 to about 0.7 mol/l. After an appropriate time, a fixing agent (other than a sulfite) is introduced into the processing container to begin simultaneous development and fixing. The entire process in quite rapid, that is less than 90 seconds.

摘要： Low silver black-and-white photographic elements, such as radiographic films, can be processed quickly using a two-stage process in which black-and-white development is carried out in the first stage for up to 30 seconds, and such development continues along with fixing in the second stage for up to 60 seconds when a fixing composition is added. Both stages are carried out in the same processing container.
