摘要: A method is provided for freezing the orientation of orientable magnetic or magnetizable pigment particles by irradiation hardening the coating layer comprising the orientable magnetic or magnetizable pigment particles through the substrate carrying the coating layer. This method can be used in the protection of security documents, such as for example banknotes and identity documents, against counterfeit and illegal reproduction.

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 comprising 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 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 invention relates to magnetic-field-generating devices which produce positively curved magnetic field lines in a concave fashion. The invention also relates to the use of these magnetic-field-generating devices for producing optical effect layers OEL which exhibit the optical impression of a positive rolling bar effect and to processes using these magnetic-field-generating devices, e.g. in the field of document security.

摘要: The present invention relates to the field of protecting value documents and value commercial goods against counterfeit and illegal reproduction. In particular, the present invention provides processes for producing optical effect layers (OELs) comprising non-spherical magnetic or magnetizable particles and comprising a motif made of at least two areas made of a single applied and cured layer, said motif being obtained by using a selective curing performed by irradiation with an actinic radiation LED source (x41) comprising an array of individually addressable actinic radiation emitters.
