PURPOSE:To prohibit the alteration of data by providing the part which is not restorable when peeling arises. CONSTITUTION:This information recording medium has a discoloring member 3 which is discolored by the peeling between the members constituting the medium. Consequently, the discoloring member 3 discolors when the members are peeled for the purpose of the alteration and, therefore, the data is not restorable. Since the discoloring member 3 discolors even in the case of the generation of the peeling between the members by an accident, the accident part can be discovered at a glance. For example, a method of laminating sheets which are colored by the destruction of microcapsules in the event of peeling is used as the above-mentioned discoloring member 3. This recording medium is produced by providing a discoloring member layer 3 via an adhesive layer 4 on a rear base body 5 and providing a recording layer 2 and a transparent base body 1 thereon. |
