    摘要： An identification medium is provided in which latent image having plural colors can be observed even when the identification medium is spaced away from a polarization filter. A cholesteric liquid crystal layer is provided as a specific polarization light reflection layer which reflects light having a specific polarized condition. An optical anisotropic layer having an optical anisotropy is provided at an upper position overlapping with the specific polarization light reflection layer. An image A fanned by an area having an optical anisotropy different from that of surroundings is formed at the optical anisotropic layer. When the identification medium is directly viewed, the influence of the optical anisotropy cannot be seen. When the identification medium is observed via a circular polarization filter, the image can be seen to have a specific color by the influence of the optical anisotropy.

    摘要： A thermosensitive ink layer 102 is composed of a thermochromic material which changes from black to a transparent state and is formed on a substrate 101 made from a PET film by heating. A cholesteric liquid crystal layer 103 on which a hologram 105 of an appropriate form is formed on the cholesteric liquid crystal layer is mounted thereon. At ordinary temperature, the thermosensitive ink layer 102 exhibits a property of light absorption and a property of selective reflection and a color shifting of the cholesteric liquid crystal layer 103 are observed. The thermosensitive ink layer 102 becomes transparent by heating and the figure 104 on the substrate 101 is also visible. The determination of the authenticity thereof is performed by utilizing the change of view. Therefore, the anticounterfeiting effects are superior to those of the discrimination techniques using conventional techniques, and this enables articles to be distinguished easily and reliably.

    摘要： A discrimination medium cannot be easily falsified. Since the visibility of the discrimination medium is unique, the discrimination medium is superior in determination of the authenticity. The discrimination medium is structured such that a cholesteric liquid crystal layer 106 and a multilayer film 103 having plural light transparent films which are laminated and are different from each other in refraction index are laminated. The reflection light reflected by the discrimination medium includes circular polarization lights which are different in polarization direction, and the discrimination medium has unique optical characteristics. A discrimination method using the above unique optical characteristics, an article to be discriminated by the discrimination medium, and a discrimination apparatus using the above unique optical characteristics are provided.

    摘要： Provided is an economical identification system suitable for use on commercial products which is difficult to duplicate, and highly identifiable. The system includes an identification medium having a high-polymer cholesteric liquid crystal material applied thereon. The high-polymer cholesteric liquid crystals selectively reflect a certain wavelength, and this wavelength changes with the change in the incident angle of the light. The liquid crystals also have the property to circularly polarize the reflected light in either sense. By taking advantages of such properties, it is possible to provide a highly identifiable structure which, however, is highly difficult to illicitly duplicate. In particular, by forming the reflective layer of a hologram with high-polymer cholesteric liquid crystals, the hologram can be used as an identification medium which is highly difficult to duplicate but easy to identify with a machine.
