US 2010/0062251 A1 · MULTICOMPONENT TAGGANT FIBERS AND METHOD

Abstract

Taggant fibers and methods of use provide for enhanced protection and security when the fibers are used in documents such as land titles, currency, passports and other documents of value. The taggant fibers consist of a minimum of two separate zones with each zone containing a different taggant to emit different wave lengths when excited. The taggants may consist of organic or inorganic compounds as are conventionally known and can be manufactured using for example polymeric materials which can be extruded during the fiber manufacturing process. A first zone may comprise a fiber sheath which includes a taggant and a second or inner zone or core which may be formed into a company logo having letters with different or the same taggants. Authentication of the fibers or documents containing such fibers can be readily viewed using conventional techniques.
