Abstract: The disclosure 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 disclosure provides processes for producing optical effect layers (OELs) on a substrate and OELs obtained thereof, said process including two magnetic orientation steps: a step of exposing a coating composition having platelet-shaped magnetic or magnetisable pigment particles to a dynamic magnetic field of a first magnetic-field-generating device so as to bi-axially orient at least a part of the platelet-shaped magnetic or magnetisable pigment particles, and a step of exposing the coating composition to a static magnetic field of a second magnetic-field-generating device, thereby mono-axially re-orienting at least a part of the platelet-shaped magnetic or magnetisable pigment particles.

Abstract: The present invention relates to the field of the protection of value documents and value commercial goods. In particular, the invention relates to methods of making an optical effect layer (OEL) associated with a substrate, the method comprising i) providing a substrate associated with a coating composition comprising magnetic or magnetizable pigment particles; ii) providing a permanent magnet assembly producing a first magnetic field; iii) providing an electromagnet assembly including a winding assembly and drive producing an oscillating or rotating second magnetic field that interacts with the first magnetic field to spin the permanent magnet assembly to rotate the first magnetic field; and iv) applying the first magnetic field while the first magnetic field rotates by spinning of the permanent magnet assembly to aggregately orient the magnetic or magnetizable pigment particles to create the optical effect layer. The invention also relates to apparatuses for creating an OEL.

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 invention relates to optical effect layers (OEL) showing a viewing-angle dependent optical effect, devices and processes for producing said OEL and items carrying said OEL, as well as uses of said optical effect layers as an anti-counterfeit means on documents. The OEL comprises a plurality of non-spherical magnetic or magnetizable particles, which are dispersed in a coating composition comprising a binder material, the OEL comprising two or more loop-shaped areas, being nested around a common central area that is surrounded by the innermost loop-shaped area, wherein, in each of the loop-shaped areas, at least a part of the plurality of non-spherical magnetic or magnetizable particles are oriented such that, in a cross-section perpendicular to the OEL layer and extending from the center of the central area to the outer boundary of the outermost loop-shaped area, the longest axis of the particles in each of the cross-sectional areas of the looped-shaped areas follow a tangent of either a negatively curved or a positively curved part of hypothetical ellipses or circles.
