Abstract

A security feature has a luminescent component and a component camouflaging the luminescent component. A security feature has a luminescent component with at least one luminophore consisting of a doped host lattice, and a component camouflaging the luminescent component, wherein for camouflaging the luminescent component, relevant properties required for identifying the luminescent component are camouflaged by the camouflaging component by the relevant properties of the luminescent component. The relevant properties being camouflaged by the camouflaging component in at least two of the relevant properties by the camouflaging component having relevant properties that correspond to the respective relevant properties of the luminescent component, thereby impeding or preventing a recognition of the luminescent component.
