Abstract:
A non-photosensitive thermally imageable element comprising a support having thereon one or more layers said element further comprising:image-forming chemistry that comprises i) image precursor chemistry that comprises a non-light sensitive silver salt as an oxidizing agent and a reducing agent therefor, and ii) a non-light sensitive catalyst or a catalyst precursor that is a non-light sensitive metal nuclei catalyst or metal catalyst precursor that upon imagewise heating is capable of promoting thermally induced image formation with said image precursor chemistry, said i) and ii) components being in reactive association and uniformly dispersed or dissolved within a binder in said one or more layers, said non-photosensitive thermally imageable element capable of being thermally addressed to provide a visible image as a result of thermally induced catalytic transformation of said image-forming chemistry.
