Abstract

Thermally imaging systems are disclosed incorporating a layer of an optical color shifting material coated over a heat sensitive layer to provide direct thermally imaging recording materials that express lustrous metallic effects when heated with a thermal printhead. The color shifting material such as interference pigments are coated as a layer applied over a heat sensitive layer. The optical color shifting materials cooperate in a unique fashion with the underlying chromogen, preferably darkly imaging, of the heat sensitive layer to yield a faux metallic toned image that appears to be an additive effect of the underlying chromogen and the chromatic tone of the color shifting material. A new class of metallic imaging thermally-responsive recording material is taught.
