Title (EN) SECURITY ARTICLES
(FR) ARTICLES FIDUCIAIRES
Abstract:
(EN) This invention is concerned with a security article including security paper especially for banknotes which comprises at least one elongate security element, said security element being visually detectable in transmitted light to display portions which transmit light and portions which are opaque, wherein said security element comprises a plurality of layers including a light-transmitting support layer and two or more series of opaque regions which are separated by at least said support layer, the arrangement of the opaque regions being such that at certain parts of the security element the said regions overlap to prevent light transmission and elsewhere along the length of the security element the opaque regions do not overlap or partially overlap such that light transmission through the security element can occur. The security article may be a credit card, identity card or travel document.
(FR) L'invention concerne un article fiduciaire comprenant du papier fiduciaire destiné en particulier aux billets de banque équipés d'au moins un élément de sécurité oblong, ledit élément de sécurité étant décelable visuellement à l'aide de lumière faisant apparaître les parties transparentes et des parties opaques. Ledit article fiduciaire comprend plusieurs couches dont une couche de support propageant la lumière et deux ou plusieurs séries de zones opaques qui sont séparées par au moins ladite couche de support. Les zones opaques sont conçues de telle sorte que dans certains endroits de l'élément fiduciaire, lesdites zones se recouvrent afin d'empêcher la propagation de la lumière, et ailleurs le long de l'élément de sécurité les zones opaques ne se recouvrent pas ou se recouvrent partiellement de telle sorte que la lumière puisse être transmise à travers l'élément de sécurité. L'article fiduciaire peut être éventuellement une carte de crédit, une carte d'identité ou un document de voyage.
