<p>A recording medium (42) utilizing an explosive compound and a dye. The dye is selected to absorb incident light radiation (40) from a chosen laser source, thereby becoming heated and triggering the explosion of the explosive material in the vicinity of the incident light radiation, to form optically detectable indicia in the medium (42). In one embodiment, the explosive is a complex transition metal azide such as a cupric azide-amine complex. In other embodiments, the dye is modified to have a thermally unstable azide group chemically associated therewith to provide the dye's absorptive capability and the explosive feature in the same molecule. The embodiments of the invention provide improved solubility of the explosive material in the dye.</p> |
