Abstract
A piece of printed material has preprinted, hidden data and includes a structure which prevents premature revealing of the hidden data. For example, an instant scratch-off lottery ticket according to the invention includes a substrate, an ink layer disposed on the substrate, the ink layer including hidden lottery data. An elemental-metal-free ink-receptive layer is provided between the ink layer and the substrate, whereby the metal-free layer prevents migration of ink from the ink layer through the substrate when the substrate has been contacted with a solvent.
