Abstract
The present invention relates to a security element for securing data carriers, having a three-layer thin-film element (20) composed of a reflection layer (22), an absorber layer (26) and a dielectric spacing layer arranged between the reflection layer and the absorber layer (24). According to the present invention, the reflection layer (22), the absorber layer (26) and the dielectric spacing layer (24) are coordinated with each other in such a way that, for viewing from the absorber layer side (26) at all viewing angles (28, 28′) and in the entire visible spectral range, the thin-film element exhibits a very low reflection and appears black.
