  • the method further comprises a step of depositing, preferably on the face of the substrate opposite to that where the first and second strips and the intermediate strip are deposited, a magnetic material, for example diluted in a solvent to form an ink.
  • This deposition step of a magnetic material can be performed before or after step a) of depositing the first and second strips and the intermediate strip. It is preferably performed before the step of cutting the substrate covered by said strips.
  • the magnetic material may be layered, in particular in the form of a strip, extending for example in a direction perpendicular to that in which extends the first and / or the second strip and / or the intermediate strip.
  • the layer of magnetic material is superimposed at least partially, or totally, on said strips.
  • It can also partially or completely cover the corresponding face of the substrate. It can also be formed in successive steps of metallization / metallization, leaving open patterns, for example one or more letters or an image.
  • the deposition of the magnetic layer can be performed by printing, for example ink jet.

Claims (16)

  1. Sicherheitselement (10), insbesondere Sicherheitsfaden, für ein Sicherheitsdokument (5), wobei das Sicherheitselement einen ersten (18) und einen zweiten (21) Bereich aufweist, die durch einen Zwischenbereich (24) getrennt sind, der eine Zwischenstruktur (33) aufweist, wobei der erste und der zweite Bereich eine erste (27) und eine zweite (30) jeweilige optisch variable Struktur aufweisen, die derart ausgebildet sind, dass für eine erste Betrachtungsrichtung (O1) die erste und die zweite Struktur voneinander verschiedene Erscheinungsbilder haben und für eine zweite Betrachtungsrichtung (O2), die von der ersten verschieden ist, die erste und die zweite Struktur einerseits ihr Erscheinungsbild gegenüber ihrem Erscheinungsbild, wenn sie in der ersten Betrachtungsrichtung betrachtet werden, verändert haben und andererseits voneinander verschiedene Erscheinungsbilder haben, wobei die Zwischenstruktur nichtmagnetische Partikel (45) aufweist, die innerhalb eines Bindemittels dispergiert sind, um eine halbdurchsichtige Schicht zu bilden, oder eine halbdurchsichtige Schicht, welche durch eine Aufbringung eines Metalls definiert ist,
    wobei die halbdurchsichtige Schicht halbreflektierend ist,
    wobei die erste und die zweite optisch variable Struktur ein und dasselbe Pigment aufweisen, welches auf den ersten und den zweiten Bereich unterschiedlich aufgebracht ist, mit einer unterschiedlichen Ausrichtung, wobei das Pigment magnetisch und plättchenförmig ist, wobei, wenn das Element in einer dritten Betrachtungsrichtung betrachtet wird, die von der ersten und zweiten Betrachtungsrichtung verschieden ist, der Zwischenbereich ein Erscheinungsbild aufweist, das mit demjenigen des in der ersten Betrachtungsrichtung betrachteten ersten Bereichs und/oder mit demjenigen des in der zweiten Betrachtungsrichtung betrachteten zweiten Bereichs identisch ist.
  2. Sicherheitselement nach Anspruch 1, wobei die erste und die zweite optisch variable Struktur jeweils eine vorzugsweise durch Prägung erhaltene Facettenstruktur aufweisen, die optional mit einem Metall bedeckt ist, insbesondere in Form einer metallischen Abflachung.
  3. Sicherheitselement nach einem der Ansprüche 1 und 2, wobei die erste und die zweite optisch variable Struktur und die Zwischenstruktur auf der gleichen Seite (38) eines Trägers (35) angeordnet sind.
  4. Sicherheitselement nach einem der vorhergehenden Ansprüche, welches eine vierte Struktur (48) aufweist, die der ersten und der zweiten optisch variablen Struktur und der Zwischenstruktur überlagert ist.
  5. Sicherheitselement nach Anspruch 4, wobei die vierte Struktur eine magnetische Schicht ist, die insbesondere durch Aufdrucken einer magnetischen Tinte erhalten wird, und/oder auf der Seite (51) des Trägers angeordnet ist, die derjenigen gegenüberliegt, auf welcher die erste und zweite Struktur und die Zwischenstruktur angeordnet sind.
  6. Sicherheitselement nach einem der vorhergehenden Ansprüche, wobei die nichtmagnetischen Partikel plättchenförmig sind.
  7. Sicherheitselement nach einem der vorhergehenden Ansprüche, wobei die nichtmagnetischen Partikel wenigstens teilweise oder sogar vollständig aus Aluminium bestehen.
  8. Sicherheitselement nach einem der vorhergehenden Ansprüche, wobei die nichtmagnetischen Partikel halbreflektierend und/oder goniochromatisch sind.
  9. Sicherheitselement nach einem der vorhergehenden Ansprüche, wobei die nichtmagnetischen Partikel zufällig und im Wesentlichen parallel zu einer Ebene ausgerichtet sind, die vorzugsweise senkrecht zu einer Betrachtungsrichtung der Fläche des Sicherheitselements ist.
  10. Herstellungsverfahren, welches die folgenden Schritte umfasst:
    a. Aufbringen, auf ein Substrat (100), von magnetischen Pigmenten in Form eines ersten (103) und eines zweiten (109) Bandes und von nichtmagnetischen Partikeln in Form eines Zwischenbandes (106), das sich zwischen dem ersten und dem zweiten Band befindet, um einen Basisfilm (112) zu bilden;
    b. Zerschneiden des Basisfilms in einer Richtung quer zur Längsrichtung eines in Schritt a) aufgebrachten Bandes, um ein Sicherheitselement (10) nach einem der vorhergehenden Ansprüche zu bilden.
  11. Verfahren nach Anspruch 9, wobei das erste Band und/oder das zweite Band und/oder das Zwischenband unterbrochen sind/ist.
  12. Verfahren nach dem vorhergehenden Anspruch, wobei das erste Band und/oder das zweite Band und/oder das Zwischenband durchgehend sind/ist.
  13. Verfahren nach einem der Ansprüche 10 bis 12, wobei in Schritt b) die quer verlaufende Schnittrichtung senkrecht zur Richtung eines in Schritt a) gebildeten Bandes ist.
  14. Verfahren nach einem der Ansprüche 10 und 11, wobei in Schritt a) eine Tinte, die nichtmagnetische Pigmente aufweist, auf das Substrat aufgebracht wird, um das Zwischenband zu bilden.
  15. Verfahren nach einem der Ansprüche 10 bis 12, wobei in Schritt a) ein Magnetfeld angelegt wird, um die magnetischen Pigmente des ersten und zweiten Bandes auszurichten.
