ABSTRACT:
A dry system for forming and transferring images is provided. The system comprises a photoactive component comprising a tacky photohardenable layer on a selected carrier sheet and a transfer component comprising a frangible color layer on a selected carrier sheet. The two components are disposed with their photohardenable and color layers in air-free contact with one another and then subjected to irradiation with actinic radiation in accordance with a selected image pattern so as to cause selected portions of the photohardenable layer to harden and fuse to confronting portions of the color layer. Then the two components are separated whereby the fused portions of the color layer are separated from its carrier sheet and transferred to the photoactive component. Thereafter the color layer remaining on the transferable component is coated with a pressure-sensitive adhesive. Finally, the transferable component is positioned with its adhesive coating engaging a receptor substrate and the rear side of its carrier sheet is rubbed hard or burnished with a suitable implement so as to cause the remaining image-defining portions of the color layer to separate from its carrier sheet and adhere to the receptor substrate.
