Abstract (en)

[origin: WO9610213A1] A thermographic imaging element containing a substrate which is coated on at least one surface thereof with a thermographic imaging system having at least one layer containing light-insensitive organic silver salt; reducing agent for silver ion; a binder; toner; and a dye which absorbs radiation in the wavelength range of about 750-1100 nm. Preferably, there is a layer adjacent to the one containing the light-insensitive organic silver salt, etc., which contains binder and additional dye which absorbs radiation in the range of about 750-1100 nm. When the thermographic imaging element is exposed to radiation of 750-1100 nm of 0.10-2.0 joules/cm<2> for 0.20-200 microseconds, an image density of about 1.0 or greater is formed. When imaging a thermographic imaging element with radiation-absorbing dye in both adjacent layers or only the layer containing binder and dye, the radiation is directed through the layer containing the light-insensitive organic silver salt, etc., before striking the adjacent layer containing radiation-absorbing dye and binder.
