  • Discrimination medium and article to be discriminated
    Patent number: 7388627
    Abstract: A breakable seal can be discriminated more easily than the conventional one. The discrimination medium 100 has a cholesteric liquid crystal layer 104, a substrate layer 105, an adhesive layer 102, and a partial peeling layer 103. The discrimination medium 100 has an adhesion strength XA between the adhesive layer 102 and the partial peeling layer 103, an adhesion strength XB between the partial peeling layer 103 and the cholesteric liquid crystal layer 104, and an adhesion strength XC between the cholesteric liquid crystal layer 104 and the substrate layer 105. The relationships XA<XB and XA<XC are satisfied at areas 106, 108, and 110. The relationships XC<XA and XC<XB are satisfied at areas 107 and 109. In the above manner, when the discrimination medium 100 is peeled from the article 101, the discrimination medium 100 is separated into a discrimination medium 116 and a discrimination medium 117.
