Abstract

A security paper is described, which includes, in combination, one or more regions printed with a magnetic ink detectable by a sorting machine, and electrically conductive and non-magnetic fibres.

Description

PAPIER CONTENANT DES ELEMENTS DE SECUR1TE
METALLIQUES ET NON MAGNETIQUES L'invention concerne un papier contenant des éléments de sécurité ayant des propriétés métalliques , plus particulièrement des fibres métalliques conductrices d'électricité, ces éléments étant non magnétiques.PAPER CONTAINING SECURITY ELEMENTS
The invention relates to a paper containing security elements having metallic properties, more particularly electrically conductive metallic fibers, these elements being non-magnetic.

On connait dà des papiers de sécurité qui contiennent des fibres métalliques.We know of security papers that contain metallic fibers.

De tels papiers ont été décrits dans le brevet R -A-2 425 937. Le papier ou structure fibreuse est fabriqué en soumettant les fibres métalliques à un traitement au moyen d'un liant hydrosoluble, de façon à enrober les fibres de liant, puis on introduit les fibres ainsi traitées dans une dispersion aqueuse de fibres de cellulose comportant éventuellement d'autres fibres non métalliques et on forme une feuille dans une madihie à papier.Such papers have been described in patent R -A-2,425,937. The paper or fibrous structure is manufactured by subjecting the metal fibers to a treatment using a water-soluble binder, so as to coat the binder fibers, then the fibers thus treated are introduced into an aqueous dispersion of cellulose fibers optionally comprising other non-metallic fibers and a sheet is formed in a paper tissue.

De tels papiers peuvent être authentifiés par détection des fibres metalliques quantitivement ou qualitativement.Such papers can be authenticated by detecting metallic fibers quantitatively or qualitatively.

Cependant, les fibres métalliques présentent aussi la propriété d'être magnétiques.However, metallic fibers also have the property of being magnetic.

En et, elles sont le plus souvent constituées d'alliages ferreux, par exemple des aciers moxydables, telles que celles décrites dans le brevet FR-A- 242050937. In and, they most often consist of ferrous alloys, for example oxidizable steels, such as those described in patent FR-A-242050937.

Or les papiers de sécunté contenant de telles fibres sont utilisés le pus souvent comme papiers pour billets de banque.However, security papers containing such fibers are often used as paper for banknotes.

Ces papiers sont imprimés par des imprimeurs au moyen d'encres magnétiques sous forme de dessins, par exemple de dessins codés. Ces encres magnétiques sont ensuite détectées sur des machines de tri
Ainsi si les fibres métalliques introduites dans ou sur le papier sont aussi magnétiques, elles troublent par interférence, le message fourni par les encres magnétiques.These papers are printed by printers using magnetic inks in the form of drawings, for example coded drawings. These magnetic inks are then detected on sorting machines
So if the metallic fibers introduced into or on the paper are also magnetic, they interfere with the message provided by magnetic inks.

L'invention a pour but de remédier à ces inconvénients.The invention aims to remedy these drawbacks.

A cet effet, l'invention concerne un papier de sécurité comportant des éléments de sécurité conducteurs d'électricité et non magnétiques.To this end, the invention relates to a security paper comprising electrically conductive security elements and not magnetic.

Les éléments de sécurité peuvent par exemple être des fibres métalliques ayant une composition métallique teIlle que ces fibres présentent un magnétisme ioiieur an magnétise détectable sur les machines de tri.The security elements can for example be metallic fibers having a metallic composition such that these fibers exhibit a magnetism or magnetism detectable on sorting machines.

Les fibres non magnétiques peuvent être déposées sur le papier ou à l'intérieur de cehici Non-magnetic fibers can be deposited on paper or inside it
