<p>PURPOSE:To provide a multiple data recording material easy to select and discriminate data, incapable of being easily forged and high in security. CONSTITUTION:A multiple data recording material 1 is constituted by providing a printing recording layer 3 due to infrared absorbing ink on the surface of a base material 2 and forming a hologram recording layer 7 consisting of a transparent infrared reflecting layer 5 and the relief hologram forming layer 6 provided on the surface of the transparent infrared reflecting layer 5 on the printing recording layer 3 through an adhesive layer 4. The hologram recording layer is reproduced by visible light and the printing recording layer is reproduced by infrared rays and the recording material is confirmed on the basis of the data of both layers.</p> |
