Abstract:
1. A security element for securing items of value, comprising a relief structure on which a thin film element having a color shift effect is disposed, wherein the thin film element comprises an absorber layer with gaps, in which no color shift effect is perceptible, and a semitransparent ink layer, which is disposed on top of the thin film element and the relief structure above the gaps in the absorber layer, wherein the color impression of the thin film element is coordinated with at least one subzone of the semitransparent ink layer when viewed under predefined viewing conditions, such that the color impressions appear very similar when viewed in a certain viewing direction, wherein the semitransparent ink layer has a light transmissivity between 30% and 95% in a spectral range in which the color impression of the thin film element is coordinated with the color impression of the semitransparent layer, and the thin film element contains either a reflection layer, an absorber layer and a dielectric spacer layer arranged between the reflection layer and the absorber layer, or at least a first absorber layer, a second absorber layer, and a dielectric spacer layer arranged between the two absorber layers.
