Abstract: A method of manufacturing a water-release transfer is disclosed in which a design in a photopolymerizable ink is applied to a substrate having a water-soluble release coating and the design is subjected to photopolymerizing radiation, e.g. ultra-violet light, to cause the ink to polymerize to a solid state. Preferably the ink comprises a mixture of a liquid unsaturated monomer and a viscous or solid prepolymer, and one or both of the monomer and prepolymer contain acryloyl or methacryloyl groups. The invention includes water-release transfers manufactured using photopolymerizable inks.

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.

Abstract: A dry release transfer is disclosed in which the design layer is formed by printing one or more inks onto a carrier sheet, at least one of the inks being a photopolymerizable composition, and subjecting the design layer to ultra-violet radiation or an electron beam discharge in order to polymerize the photopolymerizable ink. By suitable selection of polymerizable components of the ink so that the photopolymerized ink has a high Young's modulus, a stress-resisting design layer is produced which will release readily from the carrier on mechanically stressing the carrier, e.g. by rubbing lightly with a ball-point pen.
