Title: Medium of securities and method for preventing medium from being unlawfully used
Inventor: SATO SHUNSUKE
IPC: B42D15/10
Filed: 1999-05-31
Abstract: PROBLEM TO BE SOLVED: To prevent a medium of securities from being reused and at the same time, simply determine the genuineness of an object when it is found that the object suspected to be an exquisite forged item is unlawfully used by forming a heat-sensitive decolorizable ink layer which has a different color from that of a substrate and is decolorized at a specified temperature higher than normal temperatures, on the medium of securities in a region intended for displaying information. SOLUTION: A heat-sensitive decolorizable ink layer 3 is formed on the surface of a medium base material 2 of the medium 1 of securities. Further, an ink layer 4 of an ordinary ink having the same color as the heat-sensitive decolorizable ink is formed on the periphery of the heat-sensitive decolorizable ink layer 3. In this case, for the heat-sensitive decolorizable ink layer 3, ink having a different color from that of the medium base material 2 as the substrate of the ink layer 3 is used. When a part of the heat-sensitive decolorizable ink is decolorized by heating, the display contents are visible by a contrast between the color of the heat-sensitive decolorizable ink layer 3 and the color of the substrate. Consequently, the heat-sensitive decolorizable ink does not become recolorable even when it is again heated or cooled once it has been decolorized by heating.  Thus it is impossible to forge the displayed information and unlawfully use the medium.
