    摘要: 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.

    摘要: A scratch-off game card includes first and second sections. The first section is provided with a first set of game data covered by a substantially opaque scratch-off material. The second section is provided with a second set of game data covered by a substantially transparent material. The second section is further provided with a substantially transparent coating for marking the second section by rubbing with an object. The markings so made are erasable by, for example, pencil eraser or the like material.
