Abstract: The invention relates to the field of the protection of security documents such as for example banknotes and identity documents against counterfeit and illegal reproduction. In particular, the present invention provides processes for optical effect layers (OEL) exhibiting two or more nested indicia using a magnetic assembly comprising i) a soft magnetic plate (x31) comprising a) one or more voids (V) and b) one or more indentations (I) and/or one or more protrusions (P), and ii) one or more dipole magnets (x32).

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