Title (EN) A METHOD, AN ARRANGEMENT AND A CHEMICAL AGENT FOR MARKING OF BANKNOTES, VALUABLE DOCUMENTS ETC. AND DETECTION EQUIPMENT OF SUCH A MARKING
(FR) PROCEDE, AGENCEMENT ET AGENT CHIMIQUE PERMETTANT DE MARQUER DES BILLETS DE BANQUE, DES DOCUMENTS DE VALEUR, ETC. ET EQUIPEMENT DE DETECTION D'UN TEL MARQUAGE
Abstract:
(EN) The invention relates to a method, an arrangement and a solution for the marking of banknotes or securities (9, 17, 18) with a coating which is invisible to the naked eye under normal lighting. The coating, which can be executed in the form of a bar code, consists of a colourless polymer solution with a matt surface structure in the dry state, which solution is mixed with fluorescent substances, preferably consisting of colourless flakes, which can be caused to give off fluorescent light when they are illuminated with UV light. The invention also relates to an installation for the detection of such marking.
(FR) Procédé, agencement et solution permettant le marquage de billets de banque ou de valeurs (9, 17, 18) avec un revêtement invisible à l'oeil nu sous la lumière normale. Le revêtement, pouvant être réalisé sous la forme d'un code à barres, se compose d'une solution polymérique incolore ayant une structure de surface mate lorsqu'elle est sèche. On mélange la solution avec des substances fluorescentes se composant de préférence de flocons incolores dont on peut faire se dégager une lumière fluorescente, lorsqu'ils sont illuminés avec de la lumière ultraviolette. L'invention se rapporte également à une installation permettant la détection d'un tel marquage.
