<P>PROBLEM TO BE SOLVED: To solve the problem that since an opening prevention label is stuck to an adherend to certify the authenticity of the adherend, the certifying property of the opening prevention label cannot be maintained if the label can be fraudulently peeled and used by re-sticking to an unauthorized adherend. <P>SOLUTION: One surface of a transparent substrate constituting an opening prevention label is subjected to a surface activation treatment in a patterned state. The opening prevention label has such an effect that when the opening prevention label is peeled, only the transparent substrate is easily peeled and the 'pattern' appears after peeling. By applying a predetermined electric field to the opening prevention label, a predetermined light-emitting figure including a chipped portion in the 'pattern' state appears, which facilitates determination on the authenticity of the opening prevention label. <P>COPYRIGHT: (C)2013,JPO&INPIT |
