Beschreibung
Zusammenfassung:	The invention concerns an anti-counterfeiting label comprising: A) a polymeric support, optionally filled with materials in the form of fibres; B) at least three inks deposited on the polymeric support according to a defined deposition sequence; and C) at least one transparent polymeric layer that covers said at least three inks; wherein each ink comprises: (i) at least one active material detectable by Raman, in the region in the range from 1500 to 2500 cm-1 with source in the visible range, having a concentration in the range from 10"5 to 10"1 M, and (ii) at least one polymeric carrier; wherein at least two of said at least three inks are different from each other; wherein said at least three inks are deposited, the one independently of the other, in at least two distinct deposition zones of the surface of the polymeric support A); and wherein said deposition sequence of said at least three inks in said at least two distinct zones of the surface of the polymeric support defines a numerical code. L'invention concerne une étiquette anti-contrefaçon comprenant : A) un support polymère, facultativement rempli de matériaux sous forme de fibres ; B) au moins trois encres déposées sur le support polymère selon une séquence de dépôt définie ; et C) au moins une couche polymère transparente recouvrant lesdites trois encres au moins ; chaque encre comprenant : (i) au moins un matériau actif détectable par effet Raman, dans la région comprise entre 1500 et 2500 cm-1 avec une source dans la plage visible, ayant une concentration comprise entre 10"5 et 10"1 M, et (ii) au moins un vecteur polymère ; au moins deux desdites trois encres au moins étant différentes ; lesdites trois encres au moins étant déposées indépendamment dans au moins deux zones de dépôt distinctes de la surface du support polymère A) ; et ladite séquence de dépôt desdites trois encres au moins dans lesdites deux zones distinctes au moins de la surface du support polymère définissant un code numérique.
