Description

Document sécurisé par une matière opaque aux infrarouges. Document secured by an opaque infrared material.

La présente invention concerne un document sécurisé par une matière opaque aux infrarouges.The present invention relates to a document secured by an opaque infrared material.

ARRIERE PLAN DE L'INVENTION On sait que pour éviter la reproduction frauduleuse de documents, en particulier de billets de banque, il est nécessaire que le document comporte des éléments de sécuri- té qui, pour être efficaces, doivent être difficiles à reproduire tout en étant facilement identi iables .BACKGROUND OF THE INVENTION It is known that in order to avoid fraudulent reproduction of documents, in particular banknotes, it is necessary that the document includes security elements which, to be effective, must be difficult to reproduce while being easily identifiable.

Dans le passé, les éléments de sécurité étaient principalement constitués par des signes ou des caractères imprimés sur le support formant le document en utilisant des moyens d'impression de définition élevée ne permettant pas une reproduction par les moyens classiques. Toutefois, l'augmentation de la définition des moyens de reproduction par photocopie, qu'il s'agisse des photocopieurs ou des scanners associés à des imprimantes, permet d'assurer la reproduction d'un motif imprimé avec une qualité telle qu'il devient difficile de faire une distinction entre l'impression authentique et la reproduction frauduleuse.In the past, the security elements were mainly constituted by signs or characters printed on the support forming the document using high definition printing means which do not allow reproduction by conventional means. However, the increase in the definition of reproduction means by photocopying, whether photocopiers or scanners associated with printers, makes it possible to ensure the reproduction of a printed pattern with a quality such that it becomes difficult to distinguish between authentic printing and fraudulent reproduction.

Afin de faire échec à la fraude, il est donc nécessaire de multiplier les éléments de sécurité en faisant ap- pel à des techniques différentes.In order to prevent fraud, it is therefore necessary to multiply the security elements by using different techniques.

Il est connu du document FR-A-2 589 795 d'inclure, lors de la fabrication du papier, de la poudre de strontium qui rend le papier opaque aux infrarouges . La sécurité conférée par ce procédé est toutefois limitée en raison du ca- ractère homogène de l'application du strontium.It is known from document FR-A-2 589 795 to include, during the manufacture of the paper, strontium powder which makes the paper opaque to infrared. The safety conferred by this process is however limited due to the homogeneous nature of the application of strontium.

Il est également connu du document GB 1 534 403 de réaliser un fond sombre, de préférence noir, au moyen d'une encre ne contenant pas de carbone, et de superposer à ce fond un signe au moyen d'une encre de même couleur mais contenant du carbone. Ainsi, à la lumière du jour le signe ne distingue pas du fond, mais sous infrarouge seul le si- gne contenant du carbone absorbe l'infrarouge de sorte qu'un contraste apparaît sur un capteur infrarouge.It is also known from document GB 1 534 403 to produce a dark background, preferably black, by means of an ink not containing carbon, and to superimpose on this background a sign by means of an ink of the same color but containing carbon. Thus, in daylight the sign does not distinguish from the background, but under infrared only the si- A carbon-containing gene absorbs infrared so that a contrast appears on an infrared sensor.

Par ailleurs lorsque le document est reproduit par photocopie le fond sombre est obtenu par une couleur in- cluant automatiquement du carbone de sorte que le signe' n'est plus individualisé et l'ensemble apparaît noir sur un capteur infrarouge. Ce mode de réalisation assure donc une sécurisation efficace, toutefois les couleurs contenant du carbone sont nécessairement sombres, ce qui limite considé- rablement les possibilités de réalisation d'un signe qui s'insère dans le design général du billet comportant ce signe.Furthermore, when the document is reproduced by photocopy, the dark background is obtained by a color automatically including carbon so that the 'sign is no longer individualized and the assembly appears black on an infrared sensor. This embodiment therefore provides effective securing, however the colors containing carbon are necessarily dark, which considerably limits the possibilities of producing a sign which fits into the general design of the ticket comprising this sign.

OBJET DE L'INVENTION Un but de l'invention est de réaliser un élément de sécurité au moyen d'une matière absorbante l'infrarouge tout en s' intégrant dans le design du document sur lequel il est appliqué.OBJECT OF THE INVENTION An object of the invention is to provide a security element by means of an infrared absorbing material while being integrated into the design of the document to which it is applied.

BREVE DESCRIPTION DE L'INVENTION Selon l'invention on prévoit un document sécurisé comportant au moins un élément de sécurité comprenant au moins une zone ayant une couleur n'entraînant pas ou peu d'inclusion d'un composant opaque aux infrarouges lors d'une reproduction par photocopie, et au moins un signe de sécurité s'étendant dans cette zone, le signe de sécurité étant réalisé avec une matière de sécurité opaque aux infrarouges mais ayant une couleur n'entraînant pas ou peu d'inclusion d'un composant opaque aux infrarouges lors d'une reproduction par photocopie.BRIEF DESCRIPTION OF THE INVENTION According to the invention, a secure document is provided comprising at least one security element comprising at least one zone having a color which does not cause or only slightly includes an infrared opaque component during a reproduction by photocopy, and at least one security sign extending in this zone, the security sign being produced with an opaque infrared security material but having a color not causing little or no inclusion of an opaque component infrared when reproducing by photocopy.

Ainsi lors d'une reproduction par photocopie avec une encre dont le seul composant opaque aux infrarouges est habituellement le carbone, l'ensemble de l'élément de sécurité est reproduit sans inclusion de carbone ou avec une très faible inclusion de carbone. Lors d'une exposition à un rayonnement infrarouge du document falsifié, le signe de sécurité n'apparaît pas ou apparaît très faiblement de sorte qu'il est aisé de constater que le document n'est pas authentique. En outre les couleurs qui n'entraînent pas d' inclusion de carbone lors de la reproduction par photocopie sont des couleurs claires qui s'intègrent facilement au design de l'élément de sécurité et du document. Selon une version avantageuse de l'invention la matière de sécurité est transparente à la lumière visible. Ainsi, lors d'une reproduction par photocopie le signe de sécurité n'est pas perçu par les capteurs de l'appareil de reproduction qui sont réglés pour reproduire des couleurs dans le domaine visible. En outre, l'appareil de reproduction n'est pourvu d'aucune encre transparente à la lumière visible et opaque aux infrarouges. La zone de l'élément de sécurité authentique portant la matière de sécurité est donc simplement reproduite avec ses couleurs visibles de sorte que la fraude est révélée sans aucune ambiguïté lorsque le document reproduit est exposé à un rayonnement infrarouge .Thus during a photocopying reproduction with an ink whose only opaque infrared component is usually carbon, the entire security element is reproduced without inclusion of carbon or with a very low inclusion of carbon. When the falsified document is exposed to infrared radiation, the security sign does not appear or appears very weakly, so that it is easy to see that the document is not authentic. In addition, the colors which do not entail carbon inclusion during reproduction by photocopying are light colors which are easily integrated into the design of the security element and of the document. According to an advantageous version of the invention, the security material is transparent to visible light. Thus, during a reproduction by photocopy the security sign is not perceived by the sensors of the reproduction apparatus which are adjusted to reproduce colors in the visible range. In addition, the reproduction apparatus is not provided with any ink transparent to visible light and opaque to infrared. The area of the authentic security element carrying the security material is therefore simply reproduced with its visible colors so that the fraud is revealed without any ambiguity when the reproduced document is exposed to infrared radiation.

DECRIPTION DETAILLEE DE L'INVENTION Comme matière de sécurité, on utilisera avantageu- sèment des matières transparentes habituellement connues pour assurer une protection des matières plastiques contre le rayonnement infrarouge, par exemple des matières comprenant un mélange d'une aminé et d'un sel d'antimoine, ces matières étant prévues pour recouvrir les articles en ma- tière plastique à protéger sans qu'il ait été envisagé d'autres utilisations pour ces matières.DETAILED DESCRIPTION OF THE INVENTION As a safety material, use will be advantageously made of transparent materials usually known for ensuring protection of plastics against infrared radiation, for example materials comprising a mixture of an amine and a salt thereof. antimony, these materials being provided to cover the plastic articles to be protected without having been considered other uses for these materials.

Selon un mode de réalisation de l'invention selon lequel le document comprend un support fibreux, la matière de sécurité est appliquée à une partie des fibres formant le support, par exemple dans le papier constituant un billet de banque en prévoyant lors de la fabrication du papier une proportion de fibres en matière plastique contenant la matière de sécurité et qui sont mélangés avec des fibres cellulosiques. On peut également prévoir de recou- vrir des fibres avec la matière de sécurité et, si nécessaire, de recouvrir la matière de sécurité avec un vernis. On notera à ce propos que la seule présence de fibres absorbant les rayons infrarouges et même simplement distribuées de façon aléatoire dans le papier constitue en soi un signe de sécurité sans qu'il soit nécessaire que ces fibres revêtent une forme particulière.According to an embodiment of the invention according to which the document comprises a fibrous support, the security material is applied to a part of the fibers forming the support, for example in the paper constituting a bank note by providing during the manufacture of the paper a proportion of plastic fibers containing the safety material and which are mixed with cellulosic fibers. Provision may also be made to cover fibers with the security material and, if necessary, to cover the security material with a varnish. It will be noted in this connection that the mere presence of fibers absorbing infrared rays and even simply distributed randomly in the paper constitutes in itself a sign of security without it being necessary for these fibers to assume a particular form.

Selon l'invention l'élément de sécurité peut être un fil ou un ruban incorporé au document et recouvert ou imprégné de matière de sécurité ou encore un fil ou un ruban réalisé en matière plastique contenant la matière de sécurité. La matière de sécurité peut être disposée selon un motif régulier ou aléatoire ou s'étendre sur toute la longueur du fil ou du ruban.According to the invention, the security element may be a wire or a ribbon incorporated in the document and covered or impregnated with security material or else a wire or a ribbon made of plastic material containing the security material. The security material can be arranged in a regular or random pattern or extend over the entire length of the wire or ribbon.

Selon un autre aspect de l'invention la matière de sécurité peut être incorporée dans des zones transparentes d'un film de transfert à chaud dont les zones non transparentes forment des hologrammes ou sont simplement métallisées ou recouvertes d'un motif imprimé.According to another aspect of the invention, the security material can be incorporated into transparent areas of a hot transfer film, the non-transparent areas of which form holograms or are simply metallized or covered with a printed pattern.

La matière de sécurité selon l'invention peut également être appliquée sous forme d'une bande continue su- perposee à une bande métallique discontinue (au-dessus ou en dessous de celle-ci) , ou sous forme d'une bande discontinue dont les segments sont intercalés avec des segments d'une bande métallique discontinue. Ainsi, à la lumière visible la bande métallique apparaît effectivement disconti- nue tandis que sous un rayonnement infrarouge la bande est perçue par un capteur infrarouge comme une bande continue.The security material according to the invention can also be applied in the form of a continuous strip superposed on a discontinuous metal strip (above or below the latter), or in the form of a discontinuous strip, the segments are interspersed with segments of a discontinuous metal strip. Thus, in visible light the metal strip appears effectively discontinuous while under infrared radiation the strip is perceived by an infrared sensor as a continuous strip.

Selon encore un autre aspect de l'invention, la matière de sécurité est incorporée à une composition de sécurité, de préférence une encre liquide, servant à imprimer un signe ou un motif. Dans le cas où l'on souhaite que le motif soit également visible lorsque le document est soumis à un rayonnement dans le domaine du visible, la composition de sécurité comprend de préférence des pigments clairs de sorte que lors d'une reproduction frauduleuse par photoco- pie, cette reproduction n'entraînera pas d'inclusion de particules de carbone ou une très faible inclusion de par- ticules de carbone. On entend par très faible inclusion de particules de carbone une inclusion telle que le signe de sécurité apparaît beaucoup plus faiblement sous un rayonnement infrarouge que le signe de sécurité authentique. De préférence, la composition de sécurité ne comprend que des composants transparents à la lumière visible. Il est alors possible de réaliser un signe de sécurité de grande dimension s' étendant même à cheval sur d'autres éléments de sécurité non sensibles aux infrarouges. L'élément de sécurité selon l'invention apparaît alors seul lorsque le billet est soumis à un rayonnement infrarouge de sorte qu'une vérification très rapide de l'authenticité d'un billet peut être effectuée en disposant le billet dans un appareil comprenant une source de rayonnement infrarouge et un capteur in- frarouge, ce type d'appareil étant de réalisation très peu coûteuse à l'heure actuelle.According to yet another aspect of the invention, the security material is incorporated into a security composition, preferably a liquid ink, used to print a sign or a pattern. In the case where it is desired that the pattern is also visible when the document is subjected to radiation in the visible range, the security composition preferably comprises clear pigments so that during fraudulent reproduction by photoco- pie, this reproduction will not result in the inclusion of carbon particles or a very low inclusion of carbon particles. By very low inclusion of carbon particles is meant an inclusion such that the safety sign appears much more weakly under infrared radiation than the authentic safety sign. Preferably, the security composition only comprises components which are transparent to visible light. It is then possible to make a large security sign extending even straddling other security elements not sensitive to infrared. The security element according to the invention then appears alone when the ticket is subjected to infrared radiation so that a very rapid verification of the authenticity of a ticket can be carried out by placing the ticket in a device comprising a source. infrared radiation and an infrared sensor, this type of device being very inexpensive to produce at present.

Un motif entièrement transparent à la lumière visible présente en outre l'avantage de permettre des tolérances de positionnement importantes lors de l'impression du billet sans nuire à l'esthétique de celui-ci.A fully transparent pattern in visible light also has the advantage of allowing large positioning tolerances when printing the ticket without detracting from its aesthetics.

On notera qu'il n'est pas nécessaire que la matière de sécurité soit totalement opaque aux rayons infrarouges. Il suffit qu'elle absorbe suffisamment les rayons infrarouges pour qu'une différence significative puisse être obser- vée entre le signe- comportant la matière de sécurité et les zones environnantes, ou au moins que ce contraste soit sensiblement plus prononcé que sur une reproduction du document par photocopie .Note that it is not necessary for the security material to be completely opaque to infrared rays. It suffices that it sufficiently absorbs infrared rays for a significant difference to be observed between the sign comprising the safety material and the surrounding areas, or at least that this contrast is appreciably more pronounced than on a reproduction of the document by photocopy.

Bien que l'invention ait été décrite en faisant ré- férence à des couleurs n'entraînant pas l'inclusion de carbone qui est actuellement le principal composant opaque aux infrarouges dans les encres des machines de reproduction par photocopie, l'invention vise toutes les encres ayant un composant opaque aux infrarouges . Although the invention has been described with reference to colors which do not involve the inclusion of carbon which is currently the main opaque infrared component in the inks of photocopying machines, the invention is aimed at all inks having an opaque infrared component.
