ABSTRACT:
A dry release transfer is disclosed in which a releasable layer is adhered to a carrier sheet and a stress-resisting transferable design layer is printed on the releasable layer. The releasable layer is normally pre-stressed so that when an external force is applied to the carrier sheet , e.g. by rubbing with a stylus, this force is transmitted to the releasable layer. Since the releasable layer cannot yield to the applied force by stretching, because it is held by the stress-resisting layer, the adhesive bond between the releasable layer and the carrier sheet is weakened or is ruptured or partial or complete cohesive failure occurs within the releasable layer, thereby facilitating transfer of the design layer. A method of producing such transfers is also disclosed.
