Disclosed is a method for transferring an image onto a backing, the method comprising the steps of providing a transfer sheet that comprises a substrate of paper and a transfer coating bonded on a transfer side of the paper substrate; using the transfer sheet in an electrostatic dry toner copier/printer to form an image by dry toner copying onto the coating of the transfer sheet; transferring the toner image to the backing by applying suitable heat and pressure to the transfer sheet with its transfer side in contact with the backing for a sufficient time until the polymeric film material becomes tackified and adheres to the backing; and peeling off the paper from the backing while the paper is still hot. Heat of about 160°C to about 200°C, and pressure of at least 50 psi, are applied in the transferring step, and the backing has a porous surface. Also disclosed is a transfer sheet for use in imprinting an image thereon in an electrostatic dry toner copier/printer, the transfer sheet comprising a substrate of paper, and a transfer coating comprising LDPE, bonded on a transfer side of the paper substrate, whereby an image can be formed by dry toner copying onto the coating in an electrostatic dry toner copier/printer without separation of the coating from the substrate and contamination of the copier/printer.
