Abstract

Die Erfindung betrifft ein Sicherheitsmerkmal für Sicherheitspapiere, Wertdokumente und dergleichen mit einem UV-anregbaren organischen Lumineszenzstoff. Erfindungsgemäß enthält das Sicherheitsmerkmal Kern-Hülle-Teilchen (20), bei denen der organische Lumineszenzstoff als Kern (22) mit einer Hülle (24) beschichtet ist, die die chemische und/oder physikalische Beständigkeit des Lumineszenzstoffs erhöht.

The invention relates to a security feature for security papers, documents of value and the like with a UV-stimulable organic luminescent substance. According to the invention, the security feature contains core-shell particles (20) in which the organic luminescent substance is coated as core (22) with a shell (24) which increases the chemical and / or physical resistance of the luminescent substance.
