20090323066 | IDENTIFICATION MEDIUM, ARTICLE, IDENTIFICATION DEVICE, AND METHOD OF IDENTIFYING IDENTIFICATION MEDIUM - An identifying medium comprises an optical functional layer that is optically identifiable and comprises a layer containing microcapsules. The microcapsule contains a material that occurs color change by breaking the microcapsule. | 12-31-2009 |
20100015378 | TRANSPARENT PLASTIC CONTAINER FOR ANTICOUNTERFEIT SYSTEM - A transparent plastic container which is transparent, allows good design and can be used for an anticounterfeit system that determines authenticity by visual check with the use of polarization property. A transparent plastic sheet of a polystyrene-based resin having a total light transmission of 85% or higher and a haze of 7% or less is subjected to vacuum, pneumatic or vacuum/pneumatic forming at a sheet temperature ranging from a glass transition temperature plus 50 degrees C. to a glass transition temperature plus 130 degrees C., thereby obtaining a transparent plastic container having a planar portion with a strain amount of 150 nm or less. | 01-21-2010 |
20100026450 | IDENTIFICATION MEDIUM, IDENTIFICATION METHOD, AND IDENTIFICATION APPARATUS - An identification medium is to be observed via a linearly polarizing filter and includes a first liquid crystal layer that changes the wavelength of light according to the rotational angle of the linearly polarizing filter, a cholesteric liquid crystal layer, and a light absorbing layer that is provided below the cholesteric liquid crystal layer. | 02-04-2010 |
20100302486 | DISCRIMINATION MEDIUM AND PRODUCTION METHOD THEREFOR - A discrimination medium, which can have much information, can be produced on a small scale at low cost, and enables change of a sticker design at low cost, is provided. A cholesteric liquid crystal layer, having a fine asperity for forming a hologram, is formed on a transparent first substrate. A print layer composed of a black ink is formed on a transparent second substrate. The substrates are affixed to each other via a bond layer, so that a discrimination medium is obtained. In the discrimination medium, the display content obtained by the print layer is changed, so that the display content for discrimination can be changed at low cost. | 12-02-2010 |
20120236292 | IDENTIFICATION MEDIUM AND IDENTIFICATION METHOD THEREFOR - 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 formed 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. | 09-20-2012 |
20130099000 | IDENTIFICATION MEDIUM, METHOD FOR READING DATA THEREFROM, APPARATUS FOR IDENTIFICATION, AND METHOD AND APPARATUS FOR PRODUCTION THEREOF - A technique detects counterfeit products having appearances similar to authentic products with high accuracy. A cholesteric liquid crystal layer in which hologram is processed and circularly polarized light of primary rotating direction having specific central wavelength can be selectively reflected and a code forming layer in which code printed pattern that is an objective of reading is formed, are arranged in this order seen from a side from which reading is performed. The hologram image that inhibits reading of information of the code while an optical reading device reads it together with the code, and it is formed by the hologram processing. | 04-25-2013 |
20130105076 | METHOD AND APPARATUS FOR PRODUCTION OF IDENTIFICATION MEDIUM | 05-02-2013 |
20130208226 | DISCRIMINATION MEDIUM AND PRODUCTION METHOD THEREFOR - A discrimination medium, which can have much information, can be produced on a small scale at low cost, and enables change of a sticker design at low cost, is provided. The discrimination medium includes an optically transparent first substrate on which a cholesteric liquid crystal layer is formed, the cholesteric liquid crystal layer being formed with a fine asperity used for displaying a hologram, an optically transparent second substrate on which a print layer is formed, the print layer having a predetermined pattern made of ink and having a transparent portion without the ink of the pattern around the pattern, the pattern reflecting or absorbing a light of a predetermined wavelength, and a transparent adhesive layer,wherein the optically transparent first substrate, the optically transparent second substrate, and the transparent adhesive layer, are disposed in turn from a side checked visually. | 08-15-2013 |
