Abstract:
Described is a marking for a substrate. The marking comprises at least one luminescent substance (a) and at least one chiral liquid crystal polymer (CLCP) material (b) having a reflection wavelength range that overlaps at least a part of the luminescence wavelength range of (a), provided that at least a part of (b) is not located underneath (a).
