Abstract (en)
[origin: EP0582144A1] A thermal recording material containing a suitable substrate coated with an imaging system, the imaging system containing: (a) a thermally reducible source of silver; (b) a reducing agent for silver ion; (c) a dye which absorbs electromagnetic radiation in the wavelength range of about 500-1100 nm; and (d) a polymeric binder. In a preferred embodiment, the reducing agent comprises a 3-indazoline or a urea compound as a development accelerator. In another preferred embodiment, the electromagnetic radiation absorbing dye is a near-infrared light absorbing dye. In still another preferred embodiment, the electromagnetic radiation absorbing dye is present in the imaging system in a layer adjacent to a layer containing the thermally reducible source of silver and reducing agent for silver ion.
