<p>PROBLEM TO BE SOLVED: To provide a concealing data carrier capable of reducing the control load of the ink build-up amount of a scratch layer and having no necessity for using a special base material. SOLUTION: A transparent protective layer 13 is provided so as to cover the concealing data 12 formed on a base material and peelable camouflage data 14 are formed on the transparent protective layer 13 so as to be alternate with the concealing data 12 and a scratch layer 15 is formed so as to cover the camouflage data 14. Even if the concealing data 12 are seen through by light to become a visible state, the camouflage data also become visible in the same way as the concealing data 12 and, since both data are seen so as to mingle with each other, accurate data are not cleared. Therefore, the control load of the ink build-up amount of the scratch layer 15 can be reduced. The camouflage data 14 can be shaven off together with the scratch layer 15 when used and only the concealing data can be visually observed. Further, it is unnecessary to use a special base material in order to develop concealing effect and cost can be reduced.</p> |
