摘要： The apparatus and methods of the present disclosure relate to devices comprising spinning magnets driven by electric motors for use with printing or coating equipment. These devices and methods are for orienting magnetic or magnetisable pigment particles in an unhardened coating composition on a substrate. Specifically, these devices and methods are for producing optical effect layers. The apparatus comprises a holder, onto which is mounted a motor and a permanent magnet assembly. The motor is configured to spin the permanent magnet assembly. The holder is configured to be removably fixed to a base of a rotating magnetic cylinder (RMC) or a flatbed printing unit.

摘要： 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 magnetically transferring one or more indicia into a not yet hardened coating layer made of a coating composition including platelet-shaped magnetic or magnetizable pigment particles so as to produce optical effect layers (OELs) as anti-counterfeit means on security documents or security articles or for decorative purposes.

摘要： The present invention relates to the field of devices and processes for producing optical effect layers (OEL) comprising magnetically bi-axially oriented platelet-shaped magnetic or magnetizable pigment particles, in particular for producing said OELs as anti-counterfeit means on security documents or security articles or for decorative purposes. The process described herein comprises the step of a) applying on a substrate surface a radiation curable coating composition comprising platelet-shaped magnetic or magnetizable pigment particles, b) exposing the radiation curable coating composition to a dynamic magnetic field of a magnetic assembly comprising a Halbach cylinder assembly, and c) at least partially curing the radiation curable coating composition of step b) so as to fix the platelet-shaped magnetic or magnetizable pigment particles in their adopted positions and orientations, said step c) being carried out partially simultaneously or simultaneously with step b).
