Abstract: A security device is disclosed, comprising: a surface relief structure formed of a cured material, the cured material comprising a binder and dispersed therein at least a first pigment having a first detection characteristic. The surface relief structure is configured such that part(s) thereof have dimensions sufficient to accommodate a first concentration of the first pigment and other part(s) have dimensions too small to accommodate the first concentration of the first pigment, and preferably too small to accommodate substantially any of the first pigment. The detection characteristics of the cured material vary across the surface relief structure in accordance with the dimensions thereof.

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 present invention provides security documents and decorative articles comprising one or more optical effect layers (OELs) and methods for producing said OELs, said OELs comprising magnetically oriented platelet-shaped magnetic or magnetizable pigment particles in an at least partially cured coating layer (x10) and exhibiting an eye-catching optical effect thus allowing an observer to easily authenticate said OELs upon titling at viewing/observation angles between about -45° and about +45°.

Abstract: Die Erfindung betrifft ein Sicherheitselement (1) mit erhöhter Fälschungssicherheit, welches zumindest einen ersten Bereich (2) mit Strukturen (4) aufweist. Die Strukturen (4) reflektieren ein Bildmotiv (5) in unterschiedliche Raumbereiche, sodass für den Betrachter bei entsprechender Bewegung einer Lichtquelle (6) und/oder bei Veränderung eines Beobachtungswinkels ein Bewegungsbild entsteht. Bei der Bewegung der Lichtquelle (6) und/oder einer Veränderung des Beobachtungswinkels entsteht gleichzeitig eine Bewegung des Bildmotivs (5). Weiters ist eine optische Effektschicht (7) vorgesehen, welche einen zweiten Bereich (3) definiert. Die Strukturen (4) sind vollflächig oder partiell von der optischen Effektschicht (7) abgedeckt.
