<P>PROBLEM TO BE SOLVED: To provide an authenticity determining recording medium wherein the low sensitivity for information recording and the weak design property are improved. <P>SOLUTION: The authenticity judging recording medium 1 includes on one side of the transparent base material 2 in the following sequence at least: a thermosensitivity increasing layer 3; a thermosensitive breaking layer 4; a hologram forming layer 5, and a deposition layer 6. Thereby respective functions of the thermosensitive breaking layer 4, the hologram forming layer 5, and furthermore the thermosensitivity increasing layer 3 and the deposition layer 6 can be all combined to bring out an excellent anti-counterfeit property. Additionally, the underlying hologram of the thermally destructed recording portion 10 is clear and high in design property. Furthermore, when information recording by the heating means such as thermal heads, thermal destruction of the thermosensitive breaking layer 4 easily occurs since the thermosensitivity increasing layer 3 is provided, thereby enhancing the sensitivity of information recording by heat, and enabling clear recording. <P>COPYRIGHT: (C)2010,JPO&INPIT |
