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.
