摘要： Tellurium images are formed by the decomposition of tellurium (II) coordination complexes in the presence of a catalyst. The complexes are characterized in that at least one of the four coordination positions of the tellurium (II) is occupied by a sulfur containing ligand. Preferred ligands that can be coordinated with tellurium are sulfur containing bidentate anionic ligands. Complexes formed using these preferred ligands are more hydrolytically stable than other tellurium (II) complexes having sulfur containing ligands and yet are still capable of providing catalytic amplification.

摘要： A thermally imageable element can be imaged using heat alone without the need for photosensitivity or post-imaging processing. The element contains image-forming chemistry that comprises i) image precursor chemistry and ii) a catalyst or a catalyst precursor that upon imagewise heating is capable of promoting thermally induced image formation with the image precursor chemistry. The image-forming chemistry i) and ii) components are in reactive association and uniformly dispersed or dissolved within a binder in one or more layers of the element. Thus, the element is capable of being thermally addressed to provide a visible image as a result of thermally induced catalytic transformation of the image-forming chemistry.
