Abstract
Selected areas of a layer comprising an imaging material in the form of a tellurium tetrahalide adduct of an aromatic amine, exemplified by a tellurium tetrachloride adduct of dimethyl aniline, which adduct is free from any diazo groups, in the presence of a spectral photosensitizer, are subjected to the imaging effect of imaging energy, and of development, advantageously of developing energy, causing a change in the tellurium-organic imaging material in the imaged areas accompanied by a change in the detectable characteristic of the imaging material in the imaged areas. The aforesaid imaging material is especially advantageously extended in a matrix of a polymeric or resinous film-forming material. The invention in its generally most advantageous form involves an imaging step employing imaging energy and producing a latent image, followed by a heat development step to produce the detectable recorded information or image.
