A piece of printed material has preprinted, hidden data and includes a structure which prevents premature or unauthorized revealing of the hidden lottery or gaming 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 ink-receptive layer is provided between the ink layer and the substrate and includes a first security mechanism for preventing unauthorized detection of the hidden data. A second security mechanism is disposed between the ink-receptive layer and the substrate which further prevents unauthorized detection of the lottery data.

Recyclable instant scratch-off lottery ticket with improved security to

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.

Erasable scratch-off lottery ticket

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.
