Title (DE) MAGNETISCHE SIEBDRUCKFARBE ODER FLEXODRUCKFARBE UND DAMIT BEDRUCKTES SICHERHEITSELEMENT
(EN) MAGNETIC SCREEN PRINTING INK OR FLEXOGRAPHIC INK AND SECURITY ELEMENT PRINTED USING THE SAME
(FR) ENCRE DE SÉRIGRAPHIE MAGNÉTIQUE OU ENCRE D'IMPRESSION FLEXOGRAPHIQUE MAGNÉTIQUE ET ÉLÉMENT DE SÉCURITÉ IMPRIMÉ AVEC
Abstract:
(DE) Die Erfindung betrifft eine magnetische Siebdruckfarbe oder Flexodruckfarbe (30) mit einem Bindemittel (32) und magnetisch ausrichtbaren, plättchenförmigen Magnetpigmenten (34, 36), die durch die Parameter Eigenfarbe, Koerzitivfeldstärke, Remanenz und NIR-Remission charakterisiert sind. Erfindungsgemäß enthält die Siebdruckfarbe oder Flexodruckfarbe (30) zumindest zwei unterschiedliche magnetisch ausrichtbare, plättchenförmige Magnetpigmente (34, 36), die sich in zumindest einem der charakteristischen Parameter signifikant unterscheiden. Die Erfindung betrifft auch ein Sicherheitselement (12) mit einem ersten Druckbereich (14), der mit einer ersten magnetischen Siebdruckf arbe oder Flexodruckfarbe (30) der genannten Art bedruckt ist.
(EN) The invention relates to a magnetic screen printing ink or flexographic ink (30) having a binder (32) and magnetically orientable, plate‑like magnetic pigments (34, 36) which are characterized by the following parameters: inherent colour, coercivity, retentivity and NIR remission. According to the invention, the screen printing ink or flexographic ink (30) contains at least two different magnetically orientable, plate‑like magnetic pigments (34, 36), which differ significantly in at least one of the characteristic parameters. The invention also relates to a security element (12) having a first print region (14) which is printed using a first magnetic screen printing ink or flexographic ink (30) of the type mentioned.
(FR) L'invention concerne un une encre de sérigraphie magnétique ou une encre d'impression flexographique magnétique (30) comprenant un liant (32) et des pigments magnétiques (34, 36) en paillettes, pouvant être orientés magnétiquement, qui se caractérisent par les paramètres suivants: couleur propre, force coercitive, rémanence et réflexion spectrale NIR. Selon l'invention, l'encre de sérigraphie ou l'encre d'impression flexographique (30) contient au moins deux différents pigments magnétiques (34, 36) en paillettes, pouvant être orientés magnétiquement, qui diffèrent de manière significative dans au moins un des paramètres caractéristiques. L'invention concerne également un élément de sécurité (12) muni d'une zone d'impression (14) qui est imprimée avec une première encre de sérigraphie ou une encre d'impression flexographique (30) du type précité.
