Abstract

L'invention porte sur un timbre-poste ou autre timbre officiel (1) présentant un couche de marquage d'authenticité (7/23) permettant de détecter si le timbre (1) est valable car utilisé pour la première fois, ou réutilisé. Ladite couche de marquage (7/23) est une couche placée sous la couche illustrée (11) et pouvant en être séparée après l'application du timbre (1) sur un article postal ou analogue. La couche illustrée séparable (11) ne comporte pratiquement pas de marquage d'authenticité et un détecteur d'authenticité sera capable de certifier que le timbre est une réutilisation en l'absence de couche de marquage (7/23) d'une capacité suffisante pour permettre la validité de la détection. La couche illustrée (11) peut être séparée de la couche de marquage (7/23) en dissolvant l'adhésif hydrosoluble les séparant ou en décollant les couches maintenues ensemble par un adhésif pelable. La couche illustrée peut comporter une ou des fenêtres permettant de voir la couche de marquage (11). Dans certains cas, la fenêtre est délimitée dans la couche illustrée par une ligne de découpe, ou en variante elle est transparente et permet de voir la couche de marquage.
