WERT- UND SICHERHEITSDOKUMENT MIT OPTISCH ANREGBAREN FARBSTOFFEN ZUR ECHTHEITSPRÜFUNG

摘要

The document contains an optically excitable color (3) used to detect a defined emission spectrum for the document and provides a characteristic spectrum for the document. The spectrum is characteristic for the color embedded in the document and for the material of the document. The color is directly applied on or in the document or is embedded in it. The document has a color (3) embedded in a carrier material (4) to form a laser active element. Colors used for different valuable and security documents have different emission properties providing reliable differentiation of different documents. Alternatively the color is embedded in a resonator or pigment platelet consisting of a carrier layer coated on both sides by reflective coating.
