<p>PURPOSE:To prevent the formation of a local battery and to improve environmental resistance by providing a barrier layer between the required layers constituting the ticket piece. CONSTITUTION:A colored layer 2, a substrate layer 3, an aluminum thin film layer 4 constituting the printed layer, a protective layer 5, etc., are laminated on a base material 1 and further, the barrier layer 6 is provided between the layers 2 and 3. The formation of the local battery between the layers 2 and 4 is prevented by this layer 6. The corrosion of the aluminum of the layer 4 is thereby suppressed and the ticket piece provided with the printed layer having the high environmental resistance is obtd.</p> |
