Abstract

Disclosed is a device for the counterfeit protection of a banknote, a document of value or an article. The device comprises a substrate (S), and on said substrate (S) a plurality of jointly visible zones of first (1) and of second (2) hardened coatings comprising magnetically oriented pigment particles (P1, P2) in a transparent binder (M1, M2), said first (1) hardened coating having a pigment orientation imitating a first curved surface and said second (2) hardened coating having a pigment orientation imitating a second curved surface different from said first curved surface. The device is characterized in that, along a linear section through the device, at least one zone of said second (2) hardened coating is contiguously located between two zones of said first (1) hardened coating. The coatings can be aside each other, on top of each other, and/or on both sides of a transparent substrate so as to form a see-through feature. Disclosed are further a method for producing said device, the use of said device, as well as security documents carrying said device. The method comprises also consecutive selective hardening steps alternating with orienting steps.
