ABSTRACT:
The subject invention pertains to a dry transfer imaging technique comprising electrophotographic deposition of an image onto the rear side of a carrier sheet, said carrier sheet being further characterized by being abhesive to the image deposited thereupon; contacting said image-bearing rear side of said carrier sheet with an exterior surface and applying pressure to the front side of said carrier sheet, whereby transfer of said image to said exterior surface is effectuated.
The carrier sheets which are abhesvie to the deposited image form a part of the invention. In addition, novel colorless toners have been developed which, when deposited upon the image-bearing carrier sheet, enhance the adherability of said image to the exterior surface.
