It is disclosed a security element comprising a substantially flat substrate including first and second areas, wherein the first area displays a first motif and generates a first color movement effect to be seen in the first motif while the substrate gets tilted over a first angular tilting range, the second area displays a second motif and generates a second color effect to be seen in the second motif and within a second angular tilting range, the first and second angular tilting ranges are different, and the first area comprises either a micro-mirror structure or a print of magnetically oriented pigments and the second area comprises the other one of the micro-mirror structure and the print of magnetically oriented pigments.

Security element

The present invention relates to the field of magnetic assemblies and processes for producing optical effect layers (OEL) comprising magnetically oriented non-spherical magnetic or magnetizable pigment particles on a substrate. In particular, the present invention relates magnetic assemblies and processes for producing said OELs as anti-counterfeit means on security documents or security articles or for decorative purposes.
