Abstract: 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 302, having a fine asperity for forming a hologram, is formed on a transparent first substrate 301. A print layer 305 composed of a black ink is formed on a transparent second substrate 304. The substrates are affixed to each other via a bond layer 308, so that a discrimination medium 310 is obtained. In the discrimination medium 310, the display content obtained by the print layer is changed, so that the display content for discrimination can be changed at low cost.

Abstract: A transparent plastic container which is transparent, allows good design and can housed 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.
