<p>PURPOSE:To make forgery or alteration difficult or impossible, by laminating a transparent hologram sheet having inherent data recorded thereon to the surface of a base sheet. CONSTITUTION:A transparent hologram sheet 4 is laminated to the surface of a base sheet 1 having general common data recorded thereon. In the identification card thus constituted, inherent data such as a character, a mark or a photograph of face is formed to the rear of the hologram sheet 4. That is, the identification items inherent to an owner, for example, the photograph of face, nationality, the date of birth, the distinction of sex, the address, the name of a belonging organization, the type of blood or the like are recorded on the image layer 3 provided to the rear of the hologram sheet 4. The recording of these inherent data is pref. performed by thermal transfer. In this thermal transfer, a thermal transfer sheet having a dye layer containing a dye transferred by heat, so called, a sublimable dye is utilized to be imagewise heated from the rear thereof by a thermal head to form a desired image. Since a hologram can not be duplicated by a small-scaled individual or organization, secret forgery or alteration is almost impossible.</p> |
