Abstract
Selected areas of a layer comprising a tellurium tetrahalide imaging material, exemplified by tellurium tetrachloride, are subjected to the imaging effect of imaging energy, and of developing energy causing a chemical change in the tellurium tetrahalide imaging material in the imaged areas accompanied by a change in the detectable characteristic of the imaged areas. The aforesaid imaging material is extended in a matrix of a film-forming material together with a sensitizer. The application of the energy is advantageously effected in two steps, an imaging step employing imaging energy and producing a latent image, followed by a development step employing developing energy and producing the detectable recorded information or image.
