PUBLISHED DECEMBER 10, 1968 70$;476 METHOD FOR MAKING THERMOGRAPHIC COPIES FROM NON-INFRARED ABSORB- ING ORIGINALS Frank D. .Alien, deeeased,--late.-of Rochester, N.Y., by Mona Armstrong Allen, ex ecutrtx, Q55 IhornanDrive, Roehester,N.Y. s Filed Feb. 21, 1968. Published Dec. 10, 1968 Class 96-27 No Drawing. 10 Pages Specification A process is described for preparing thermograpbie copies from substantially non-infrared-absorptive original images. The process comprises exposing a photosensitive element to actinic radiation through the original, forming with the element an infra-red absorptive image and then employing this infrared absorptive -image as a second generation original in a thermographic copying process. In one embodiment an infrared absorptive image is pre- ,pared by employing as the photosensitive element a photothermographic element which undergoes a change in tackifying point upon photoexposure. After heating, cornpo'sition from areas having a lower taoltifying pointjs "transferred to a receiving sheet, if an infrared absorptive colorant is incorporated in the composition, or is toned with an infrared absorptive material. An example of a suitable photothermographic element is one containing a layer of a photosensitive copolyester composition con- *taining as an integral portion theiight-sensitive grouping 111a second embodiment an infrared absorptive imagc;is ,prepared by the image-wise photodestruction of a photo- "?oieachable dye, such as a polymethine pyrylium dye or a polymethine cyanine dye, contained in the photosensitive element.
