Patent ID: 7455323

Claim:
A method of manufacturing a lottery ticket comprising: providing a substrate layer; defining a game area on a front surface of the substrate layer; printing indicia defining game data on the substrate layer in the game area; the substrate layer being arranged to, or having one or more coatings thereon which are arranged to, prevent access to the game data from a rear surface of the substrate; applying at least one fixing layer over the game data in the game area which is arranged to prevent release of the printed game data from the substrate layer; applying at least one opaque scratch-off layer over the fixing layer, applying a rear surface of an adhesive layer onto at least a part of a front surface of the opaque scratch-off layer so that the adhesive layer when applied has an exposed front surface; providing a metal layer carried on a transfer carrier layer so that the metal layer has an exposed first surface and a second surface attached to the carrier layer; contacting the exposed first surface of the metal layer onto the exposed front surface of the adhesive layer; causing those parts of the metal layer which are contacted by the front surface of the adhesive layer to transfers from the carrier layer onto the front surface of the adhesive layer leaving other parts of the metal layer which are not contacted by the front surface of the adhesive layer remaining attached to the carrier layer such that the parts of the metal layer which remain attached to the carrier layer are carried away from the ticket; and arranging the scratch-off layer with the adhesive layer and the portions of the metal layer thereon such that the scratch-off layer, the adhesive layer and the portions of the metal layer separate from the fixing layer and break down into fragments when scratched by a player.
