Abstract

The invention relates to a security feature having a luminescent component and a component camouflaging the luminescent component. The invention is based on a security feature having a luminescent component that has at least one luminophore consisting of at least one doped host lattice and a component camouflaging the luminescence component wherein the camouflaging component has chemical elements that have structural chemical properties similar to the chemical elements of the luminescent component wherein the chemical elements of the camouflaging component and the chemical elements of the luminescent compartment are formed by different chemical elements.
