Abstract
Described herein is a process for heat transfer printing, the process comprising: electrostatically printing a transparent release composition onto a transfer material to form a release layer disposed on the transfer material; electrostatically printing an electrostatic ink composition on the release layer to form an image layer disposed on the release layer; contacting a thermoplastic film with the image layer; contacting the thermoplastic film with a target substrate under conditions such that the thermoplastic film adheres to the target substrate and the release layer is softened; and separating the target substrate and the transfer material such that the thermoplastic film, image layer and release layer are transferred to the target substrate. A heat transferrable printed image is also described herein.
