Title

(DE) SICHERHEITSELEMENT MIT DIFFRAKTIVEN STRUKTUREN

(EN) SECURITY ELEMENT HAVING DIFFRACTIVE STRUCTURES

(FR) ÉLÉMENT DE SÉCURITÉ AYANT DES STRUCTURES DE DIFFRACTION

Abstract

(DE) Die Erfindung betrifft Sicherheitselement (1) insbesondere für Wertpapiere, Sicherheitspapiere oder Sicherheitsgegenstände, wie Banknoten, Ausweise, Kreditkarten, das einen ersten Bereich (2) mit optisch wirksamen, diffraktiven ersten Strukturen (3) aufweist, mittels der ein erzeugter Gesamteindruck achromatisch erscheint, und der zumindest teilweise mit einer optischen Effektschicht (4) beschichtet ist, sodass der Gesamteindruck unter einem ersten Betrachtungswinkel (5) in einer ersten Farbe (6) erscheint und unter einem zweiten Betrachtungswinkel (7) in einer zweiten Farbe (8) erscheint. Das Sicherheitselement umfasst einen zweiten Bereich (9) mit optisch wirksamen, diffraktiven zweiten Strukturen (10), der ebenfalls mit der optischen Effektschicht (4) beschichtet ist und die zweiten Strukturen (10) in ihren Struktureigenschaften gegenüber den ersten Strukturen (3) derart unterschiedlich ausgebildet sind, dass der Gesamteindruck in dem zweiten Bereich (9) unter dem ersten Betrachtungswinkel (5) in zumindest einer dritten Farbe (12) erscheint.

(EN) The invention relates to a security element (1), in particular for value papers, security papers, or security objects, such as banknotes, identification documents, and credit cards, having a first region (2) which has first optically active diffractive structures (3), by means of which a generated overall impression appears achromatic, the first region being at least partly coated with an optical effect layer (4) such that the overall impression appears in a first color (6) at a first viewing angle (5) and in a second color (8) at a second viewing angle (7). The security element comprises a second region (9) which has second optically active diffractive structures (10) and which is likewise coated with the optical effect layer (4), and the second structures (10) are designed to have different properties than those of the first structures (3) such that the overall impression in the second region (9) appears in at least one third color (12) at the first viewing angle (5).

(FR) L'invention concerne un élément de sécurité (1), en particulier pour des papiers de valeur, des papiers de sécurité ou des objets de sécurité, tels que des billets de banque, des documents d'identification et des cartes de crédit, ayant une première région (2) qui a des premières structures diffractives optiquement actives (3), au moyen desquelles une impression globale générée apparaît achromatique, la première région étant au moins partiellement revêtue d'une couche à effet optique (4) de telle sorte que l'impression globale apparaît dans une première couleur (6) à un premier angle de visualisation (5) et dans une seconde couleur (8) à un second angle de visualisation (7). L'élément de sécurité comprend une seconde région (9) qui a des secondes structures diffractives optiquement actives (10) et qui est également revêtue de la couche à effet optique (4), et les secondes structures (10) sont conçues pour avoir des propriétés différentes de celles des premières structures (3) de telle sorte que l'impression globale dans la seconde région (9) apparaît dans au moins une troisième couleur (12) au premier angle de visualisation (5).
