Patent ID: 7291233

Claim:
A process for applying a transferable image onto a partially roughened or irregular surface of a fixed wall of concrete or layer covered with plaster, the process comprising: applying a transferable image onto a first surface of a transfer sheet by processing said transferable image by computer and printing said transferable image on said first surface with an electrostatic printer; applying a sealant coating directly over the applied transferable image on the first surface, which sealant coating is able to bind the ink of the image; drying the sealant coating so as to sandwich the transferable image between the sealant coating and the first surface, whereby after drying, said sealant coating does not have adhesive tackiness or heat or pressure activated adhesiveness; applying an adhesive binder onto the roughened or irregular surface of the wall; placing the sealant coating applied transfer sheet against said partially roughened or irregular surface of the wall with said first surface in a facing relationship with said adhesive binder on the wall, the sealant coating in dried form being able to protect the transferable image from any distortion and irregularity when mounted on the roughened or irregular surface of said wall; applying pressure to press said first surface of the placed transfer sheet against the wall, so as to thereby transfer the transferable image onto the wall; and removing the pressure-applied transfer sheet from the wall.
