Title
(DE) OPTISCH VARIABLES SICHERHEITSELEMENT
(EN) OPTICALLY VARIABLE SECURITY ELEMENT
(FR) ÉLÉMENT DE SÉCURITÉ OPTIQUEMENT VARIABLE
Abstract
(DE) Die Erfindung betrifft ein optisch variables Sicherheitselement (12) zur Absicherung von Wertgegenständen, dessen Flächenausdehnung eine darauf senkrecht stehende z- Achse definiert, mit einem reflektiven Flächenbereich, der zumindest zwei, aus unterschiedlichen Betrachtungsrichtungen erkennbare Erscheinungsbilder (14-A, 14-B) zeigt. Der reflektive Flächenbereich enthält zwei Reliefstrukturen (24, 34), die in z-Richtung in unterschiedlichen Höhenstufen angeordnet sind und eine tiefer liegende und eine höher liegende Reliefstruktur bilden, die jeweils mit einer dem Reliefverlauf folgenden reflexionserhöhenden Beschichtung (26, 36) versehen sind. Die höher liegende Reliefstruktur (34) zeigt einen ersten optisch variablen Effekt in einer ersten Farbe und die tiefer liegende Relief Struktur (24) ist durch die höher liegende reflexionserhöhende Beschichtung selbst hindurch, oder durch Rasterzwischenräume (54) oder Aussparungen in der höher liegenden reflexionserhöhende Beschichtung (36) hindurch sichtbar und zeigt einen zweiten optisch variablen Effekt in einer zweiten, unterschiedlichen Farbe zeigt. Das Sicherheitselement ist in einer innenliegenden, vollflächig oder bereichsweise (60) vorgesehenen Schicht mit zumindest einem maschinenlesbaren Merkmalsstoff (62) versehen.
(EN) The invention relates to an optically variable security element (12) for safeguarding valuable objects, the surface area of said security element defining a z-axis perpendicular thereto, comprising a reflective surface region exhibiting at least two images (14-A, 14-B) which are discernible from different viewing directions. The reflective surface region contains two relief structures (24, 34) that are arranged at different vertical levels in the z-direction and form a lower-lying and a higher-lying relief structure, each of which is provided with a reflection-increasing coating (26, 36) that follows the course of the relief. The higher-lying relief structure (34) exhibits a first optically variable effect in a first color, and the lower-lying relief structure (24) can be viewed through the higher-lying reflection-increasing coating or through grid intermediate spaces (54) or recesses in the higher-lying reflection-increasing coating (36) and exhibits a second optically variable effect in a second different color. The security element is provided in an inner coating which is provided over the entire surface or in some regions (60) and comprises at least one machine-readable feature substance (62).
(FR) L'invention se rapporte à un élément de sécurité optiquement variable (12) permettant la protection d'objets de valeur, la surface dudit élément de sécurité définissant un axe z perpendiculaire à ce dernier, comprenant une région de surface réfléchissante présentant au moins deux images (14-A, 14-B) qui sont discernables à partir de différentes directions de visualisation. La région de surface réfléchissante contient deux structures en relief (24, 34) disposées à des niveaux verticaux différents dans la direction z et formant une structure en relief inférieure et supérieure, dont chacune est pourvue d'un revêtement augmentant la réflexion (26, 36) qui suit le tracé du relief. La structure en relief supérieure (34) présente un premier effet optiquement variable dans une première couleur, et la structure en relief inférieure (24) peut être vue à travers le revêtement augmentant la réflexion supérieur ou à travers des espaces intermédiaires de grille (54) ou des évidements dans le revêtement augmentant la réflexion supérieur (36) et présente un second effet optiquement variable dans une seconde couleur différente. L'élément de sécurité est disposé dans un revêtement interne disposé sur toute la surface ou dans certaines régions (60) et comprend au moins une substance caractéristique lisible par machine (62).
