TEM AND MERCHANDISE, MARKING THE SAME, METHODS FOR MARKING, IDENTIFICATION, AUTHENTICATION, MONITORING AND TRACKING THE SAME AND METHOD FOR ESTABLISHING AND IMPROVING DETECTABILITY. The present invention describes a label for a substrate. The marking comprises at least one luminescent substance (a) and at least one chiral liquid crystal polymer (CLCP) material (b) with a reflection wavelength range overlapping at least a part of the reflection wavelength range. luminescence of (a) provided that at least a part of (b) is not located under (a). |
