PROBLEM TO BE SOLVED: To provide a card for which the conventionally used material can be used as it is by forming a light condensing fluorescent dye on a transparent substrate by printing. SOLUTION: This is a card on which a transparent front cover sheet, a transparent front core sheet, a milky white and opaque center core sheet, a transparent rear core sheet, and a transparent rear cover sheet all made of resin materials are successively laminated. At least in a part of a region between the front cover sheet and the front core sheet, there is formed a printing layer by a light condensing fluorescent dye ink. At least in a part of a region between the rear core sheet and the rear cover sheet, there is formed a printing layer by a light condensing fluorescent dye ink having a color different from that of the light condensing fluorescent dye ink. On the laminated face of the front cover sheet and/or the rear cover sheet of the card, a pattern printing layer is formed. COPYRIGHT: (C)2009,JPO&INPIT |
