Abstract: A lottery ticket has game data printed on a substrate in a game data area either directly onto the substrate or onto a covering layer where the game data area is firstly covered by a scratch-off layer which contains a white pigment following which the scratch-off layer is covered by a plurality of layers of ink each of which contains pigment defining different colors for the different layers and which are different from the white pigment of the scratch-off layer so as to form a four color pattern. The scratch-off layer and the inks are sufficiently transparent to view the game data therethrough so that the removal of the scratch-off layer and the inks acts to mark the game data by showing it in a different color from the original view through the layers.

Abstract: A lottery ticket having a substrate layer with game data printed in a game area and which is arranged to prevent access to the game data from a rear surface of the substrate and has at least one fixing layer applied over the game data in the game area so as to prevent release of the printed game data from the substrate layer and at least one opaque scratch-off layer applied over the sealing layer, the scratch-off layer being arranged such that it separates from the sealing layer and breaks down into fragments when scratched by a player, is modified by the addition of an adhesive layer applied over at least a part of the opaque scratch-off layer and a metal layer attached to the adhesive layer. The metal layer and the adhesive layer are arranged such that they break down into fragments with the scratch-off layer when scratched by the player and may provide both enhanced security and an improved appearance.
