AI Technical Summary

Technical Problem

The prior art is difficult to effectively manufacture a custom optical effect layer (OEL) for safe documents and decorations, especially when displaying personal variable indications.

Method used

OELs are prepared using non-spherical magnetic or magnetizable pigment particles by applying wet-on-wet states of the radiation hardenable coating and the top coating on the substrate to cover each other, using contactless fluid microjet positioning techniques, such as inkjet printing.

Benefits of technology

The rapid and reliable production of OELs with multiple indicator areas on an industrial scale without the need for dedicated magnetic field devices or photocoats, suitable for displaying personal variable indications and other optical effects.

Abstract

The present invention relates to the field of protection of security documents, such as for example banknotes and identity documents against counterfeiting and illegal copying. In particular, the present invention provides a method for producing an optical effect layer (OEL) exhibiting one or more indicia (x30) on a substrate (x20), comprising the steps of exposing a coating layer (x10) comprising non-spherical magnetic or magnetizable pigment particles to a magnetic field of a magnetic field generating device in order to orient at least a portion of the non-spherical magnetic or magnetizable pigment particles, applying a top coating composition on the coating layer (x10) in the form of one or more indicia (x30), and at least partially curing the coating layer (x10) and the one or more indicia (x30) in a curing device (x50).
