Abstract

Abstract Selected areas of a layer comprising organo-tellurium compound imaging materials, illustrative of which is Bis (1,5-diphenyl-1,3,5-propanetrione) tellurium dichloride, in the presence of a photosensitizer, are subjected to the imaging effect of imaging energy, and of development, advantageously of developing energy, causing a change in the organo-tellurium imaging material in the imaged areas accompanied by a change in a detectable characteristic of the imaging materials 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.
