Abstract
A process for making a radiation filter element comprises the steps of: exposing part of an assemblage to infrared radiation, the assemblage comprising a donor comprising (1) a support capable of transmitting infrared light, and (2) a transferable layer comprising a transferable material and an infrared-absorbing dye, the transferable layer of the donor being in contact with a receiver to provide an exposed assemblage comprising an exposed part of the transferable layer and an unexposed part of the transferable layer; separating the receiver and the support of the exposed assemblage to obtain an imaged receiver and a spent donor, wherein the imaged receiver comprises the receiver, a transferred portion of the transferable material and a transferred portion of the infrared-absorbing dye, said transferred portion of the IR dye having a color and the spent donor comprises the support and a retained portion of the transferable layer; and heating the transferred portion of the transferable material and the transferred portion of the infrared-absorbing dye at a temperature ranging from about 100 degrees Celsius to about 350 degrees Celsius for a period of time sufficient to thermally dec…
