Title
(EN) A SECURITY PRODUCT, A FILM AND A METHOD OF MANUFACTURE OF A SECURITY PRODUCT
(FR) PRODUIT DE SECURITE, FILM ET PROCEDE DE FABRICATION D'UN PRODUIT DE SECURITE
Abstract
(EN)
The present invention provides in a first aspect a method of manufacture of a security product suitable for use with security articles including security paper such as that used for banknotes, wherein a magnetic metal (10) is deposited on a film of polymeric substrate as the substrate passes through a solution containing the magnetic metal, and a preparatory operation is carried out on a surface of the substrate prior to immersion of the substrate in the solution, characterised in that the preparatory operation ensures that magnetic metal (10) is deposited on the substrate in a chosen pattern such that when the security product is produced from the film by cutting the film, the magnetic metal (10) on the security thread has a specific pattern and provides both a visual discernible security feature and a magnetically detectable security feature. The present invention provides in a second aspect a security product for security paper such as banknotes, the security thread comprising a polymeric substrate, catalytic material covering at least a portion of one surface of the polymeric substrate, and a layer of electrolessly deposited magnetic metal (10) covering at least a portion of the catalytic material with a depth in the range 0.01-3.0 $g(m)m.
(FR)
Selon un premier aspect de la présente invention, un procédé de fabrication d'un produit de sécurité est conçu pour s'appliquer à des articles de sécurité incluant le papier fiduciaire tel que celui utilisé pour les billets de banque, ce procédé consistant à déposer un métal magnétique (10) sur un film de substrat polymère tandis que l'on fait passer le substrat dans une solution contenant le métal magnétique, une opération préparatoire étant effectuée sur une surface du substrat avant son immersion dans une solution. Ce procédé se caractérise en ce que l'opération préparatoire permet que le métal magnétique (10) soit déposé sur le substrat selon un motif choisi de sorte que, lorsqu'on réalise le produit de sécurité par découpage du film, le métal magnétique (10) déposé sur le fil de sécurité ait un motif spécifique et ait à la fois une caractéristique de sécurité discernable à l'÷il nu et une caractéristique de sécurité détectable magnétiquement. Selon un second aspect, la présente invention se rapporte à un produit de sécurité pour papier fiduciaire tel que des billets de banque, le fil de sécurité comprenant un substrat polymère, un matériau catalytique recouvrant au moins une partie d'une surface du substrat polymère, et une couche de métal magnétique (10) déposée par un procédé chimique, recouvrant au moins une partie du matériau catalytique à une profondeur comprise entre 0,01 et 3 $g(m)m.
