Abstract

The device (1) has two juxtaposed printed patterns (2, 4) to cover a printed pattern (8), where each pattern is printed with an ink containing fluorescent pigments. Composition of the inks of the patterns (2, 4) is such that the patterns (2, 4) form an opaque filter under an UV ray for radiation emitted towards or re-transmitted by the pattern (8) to make the pattern (8) to remain invisible. The effect of filter is diminished or disappeared when a document is exposed to another UV ray (UV2) such that the pattern (8) appears in a color distinct from colors of the patterns (2, 4).

Description

Domaine de l'inventionField of the invention

L'invention se rapporte à des dispositifs destinés à décourager la contrefaçon de documents de valeurs (titres, billets de banque, etc.) ou de documents de sécurité tels que des pièces d'identité, cartes d'accès à des zones réservées, cartes de crédit et autres.The invention relates to devices intended to discourage the counterfeiting of valuable documents (securities, banknotes, etc.) or security documents such as identity documents, access cards to reserved areas, cards credit and others.

État de la techniqueState of the art

On connaît notamment par EP 0 265 323 et GG 2 189 800 des documents présentant des zones imprimées qui, exposées à un rayonnement UV, produisent, par l'utilisation de pigments fluorescents, deux zones de couleurs contrastées (vert-rouge par exemple). Le problème est qu'en général, les usagers se contentent de vérifier s'il y a ou non fluorescence, sans pour autant authentifier les couleurs en elles-mêmes. Il y a là une faille que des contrefacteurs bien équipés pourraient contourner.We know in particular by EP 0 265 323 and GG 2 189 800 documents having printed areas which, exposed to UV radiation, produce, by the use of fluorescent pigments, two areas of contrasting colors (green-red for example). The problem is that in general, users are content to check whether there is fluorescence or not, without authenticating the colors themselves. There is a loophole that well-equipped counterfeiters could circumvent.

On connaît par EP-1 179 808 un procédé permettant un repérage plus précis de documents frauduleux. Grâce à l'usage de pigments fluorescents de caractéristiques soigneusement calibrées, on obtient, lorsqu'un document ainsi sécurisé est soumis successivement à deux sources UV de longueur d'ondes différentes, des motifs de couleurs semblables ou dissemblables, permettant l'authentification.We know by EP-1,179,808 a method for more accurate tracking of fraudulent documents. Thanks to the use of fluorescent pigments with carefully calibrated characteristics, when a document thus secured is successively subjected to two UV sources of different wavelengths, similar or dissimilar color patterns, allowing authentication, are obtained.

Résumé de l'inventionSummary of the invention

Un but de l'invention est de permettre un contrôle aisé et fiable de l'authenticité d'un document.An object of the invention is to allow easy and reliable control of the authenticity of a document.

Un autre but de l'invention est de faire appel à une technologie simple à mettre en oeuvre, mais difficile, voire impossible à reproduire par des contrefacteurs potentiels.Another object of the invention is to use a simple technology to implement, but difficult or impossible to reproduce by potential counterfeiters.

L'objet de l'invention est un dispositif d'authentification de document. Ce document porte au moins deux zones juxtaposées imprimées chacune à l'aide d'une encre contenant des pigments fluorescents. La composition de ces encres est telle que lorsque le document est exposé à un premier rayonnement UV, de longueur d'onde déterminée, les au moins deux zones apparaissent sous une couleur identique pour l'oeil humain, cependant que lorsque le document est exposé à un deuxième rayonnement UV (d'une autre longueur d'onde déterminée), elles apparaissent sous des couleurs distinctes. Ces au moins deux zones juxtaposées recouvrent chacune, au moins partiellement, au moins une troisième zone. Cette troisième zone est imprimée, elle aussi, à l'aide d'une encre contenant des pigments fluorescents. La composition des encres de ces au moins deux zones est établie de telle façon qu'elles forment chacune un filtre opaque sous le premier rayonnement UV pour le rayonnement émis vers ou retransmis par la troisième zone, de sorte que cette au moins une troisième zone reste invisible. Cet effet de filtre disparaît ou s'atténue lorsque le document est exposé au deuxième rayonnement UV, de sorte que la troisième zone apparaît à ce moment sous une couleur distincte de celles des au moins deux autres zones.The object of the invention is a document authentication device. This document carries at least two juxtaposed zones each printed with an ink containing fluorescent pigments. The composition of these inks is such that when the document is exposed to a first UV radiation, of determined wavelength, the at least two zones appear in an identical color for the human eye, whereas when the document is exposed to a second UV radiation (of another determined wavelength), they appear in distinct colors. These at least two juxtaposed zones each cover, at least partially, at least a third zone. This third zone is printed, too, using an ink containing fluorescent pigments. The composition of the inks of these at least two zones is established in such a way that they each form an opaque filter under the first UV radiation for the radiation emitted towards or retransmitted by the third zone, so that this at least one third zone remains invisible. This filter effect disappears or diminishes when the document is exposed to the second UV radiation, so that the third zone appears at this time in a color distinct from those of the at least two other areas.

Suivant une forme de réalisation préférée, les motifs formés par les trois zones n'apparaissent pas distinctement de leur arrière-plan en lumière ambiante.According to a preferred embodiment, the patterns formed by the three zones do not appear distinctly from their background in ambient light.

Suivant une forme de réalisation avantageuse, la composition des encres des au moins deux zones est telle que, sous le premier rayonnement UV (UV1), elles forment un filtre opaque pour le rayonnement réémis par l'au moins une troisième zone.According to an advantageous embodiment, the composition of the inks of the at least two zones is such that, under the first UV radiation (UV1), they form an opaque filter for the radiation reemitted by the at least one third zone.

Suivant une autre forme de réalisation avantageuse, la composition des encres des au moins deux zones est telle que, sous le premier rayonnement UV, elles forment un filtre opaque pour la part de ce rayonnement susceptible d'atteindre l'au moins une troisième zone.According to another advantageous embodiment, the composition of the inks of the at least two zones is such that, under the first UV radiation, they form an opaque filter for the part of this radiation likely to reach the at least one third zone.

Le dispositif d'authentification de l'invention comprend avantageusement au moins deux troisièmes zones.The authentication device of the invention advantageously comprises at least two third zones.

Un autre objet de l'invention est un document de sécurité qui comprend au moins un dispositif d'authentification comme décrit ci-dessus.Another object of the invention is a security document which comprises at least one authentication device as described above.

Description détaillée de modes de réalisation particuliersDetailed description of particular embodiments

La Fig. 1 montre, en coupe, et en épaisseurs fortement exagérées, le mode de réalisation général du dispositif de l'invention 1. Deux motifs contigus 2,4 imprimés à l'aide d'encres de compositions différentes contenant chacune des pigments fluorescents sont appliqués sur un support adéquat 6. Un exemple de composition pour la couleur du motif 2 est [Rouge bi-fluo jaune/orange, SICPA Rouge jaunâtre 20, SICPA Blanc transparent 20, SICPA Bi-fluo jaune-orange 60] et pour le motif 4 [Rouge fluo jaune, SICPA Rouge jaunâtre 20,0, SICPA Blanc transparent 75,0, SICPA Incolore fluo jaune 1,5, SICPA Incolore fluo jaune 2,0, SICPA Incolore fluo rouge 1,5]. Ce support 6 peut être un papier destiné à la fabrication de papier-monnaie, de documents authentiques, du plastique, etc. Ces motifs 2, 4 recouvrent (dans l'exemple montré, complètement) un troisième motif 8, imprimé à l'aide d'une encre de composition distincte de celle formant des deux autres motifs, comprenant elle aussi des pigments fluorescents. En l'occurrence, on peut utiliser la composition suivante: Blanc fluo rouge, Sun Chemical Blanc couvrant 50, SICPA Invisible fluo rouge 50]. Exposés à une lumière ambiante, comme à la Fig. 2, le dispositif 1 apparaît sous une couleur quelconque (couleur A, rendue par un pointillé), par exemple sous forme d'une pastille colorée. Le dispositif peut aussi être dissimulé dans un motif abstrait (voir Fig.3) (ici aussi, de couleur A) ou non, imprimé sur le support 6.The Fig. 1 shows, in section, and in greatly exaggerated thicknesses, the general embodiment of the device of The invention 1. Two contiguous patterns 2.4 printed with inks of different compositions each containing fluorescent pigments are applied to a suitable support 6. An exemplary composition for the color of the pattern 2 is yellow / orange fluo, SICPA Yellowish red 20, SICPA White transparent 20, SICPA Bi-fluo yellow-orange 60] and for pattern 4 [Yellow fluo red, SICPA Yellowish red 20.0, SICPA White transparent 75.0, SICPA Colorless yellow fluo 1.5, SICPA Fluorescent yellow 2.0, SICPA Fluorescent red 1.5]. This support 6 may be a paper intended for the manufacture of paper money, authentic documents, plastic, etc. These patterns 2, 4 cover (in the example shown, completely) a third pattern 8, printed with an ink composition distinct from that forming the other two patterns, also including fluorescent pigments. In this case, the following composition can be used: Fluorescent white red, Sun Chemical White covering 50, SICPA Invisible fluo red 50]. Exposed to ambient light, such as Fig. 2 , the device 1 appears in any color (color A, rendered by a dotted line), for example in the form of a colored pellet. The device can also be hidden in an abstract pattern (see Fig.3 ) (here also, of color A) or not, printed on the support 6.

La Fig. 4 montre ce qui se passe lorsqu'un document muni du dispositif de l'invention est soumis au rayonnement d'une lampe à ultraviolets 10 émettant dans une première gamme de longueur d'ondes (UV1): les deux motifs 2,4, apparaissent à l'oeil humain sous une couleur phosphorescente identique B (rendue ici symboliquement par des hachures horizontales), le troisième motif restant invisible.The Fig. 4 shows what happens when a document provided with the device of the invention is subjected to the radiation of an ultraviolet lamp 10 emitting in a first wavelength range (UV1): the two patterns 2,4, appear at the human eye in an identical phosphorescent color B (symbolically rendered here by horizontal hatching), the third motif remaining invisible.

La Fig. 5 montre ce qui se passe lorsque le même document est soumis au rayonnement d'une deuxième lampe à ultraviolets 10 émettant dans une deuxième gamme de longueur d'ondes (UV2) : chacun des motifs 2, 4, apparaît sous une couleur phosphorescente différente (couleurs rendues par des hachures obliques gauche ou droites). Le troisième motif apparaissant en une troisième couleur (hachures verticales). La transition d'une pastille de couleur uniforme en trois zones de couleurs distinctes (et de préférence violemment contrastées) est pour l'usager une preuve évidente de l'authenticité du document, cependant que la technologie nécessaire pour rendre les mêmes effets est totalement hors de portée d'un contrefacteur même bien équipé.The Fig. 5 shows what happens when the same document is irradiated with a second ultraviolet 10 emitting in a second wavelength range (UV2): each of the patterns 2, 4, appears in a different phosphorescent color (colors rendered by left or right oblique hatching). The third pattern appears in a third color (vertical hatching). The transition from a uniform color pellet to three distinct (and preferably violently contrasting) color zones is for the user an obvious proof of the authenticity of the document, while the technology necessary to render the same effects is totally out of the picture. scope of a counterfeiter even well equipped.

Pour obtenir l'effet recherché, on a recours à une technologie relativement simple, mais complexe à mettre en oeuvre :To obtain the desired effect, we use a relatively simple technology, but complex to implement:

Il est en effet nécessaire d'ajuster d'abord la composition des encres composant les motifs 1 et 2 de façon à obtenir une même couleur sous un rayonnement UV1, ce qui est déjà une tâche malaisée pour un éventuel contrefacteur.It is indeed necessary to first adjust the composition of the inks constituting the units 1 and 2 so as to obtain the same color under UV1 radiation, which is already a difficult task for a possible counterfeiter.

Par ailleurs, ces encres doivent chacune comprendre des composants bloquant le passage du rayonnement émis par les pigments du motif 8 sous l'effet de l'excitation due à un type de rayonnement précis, en l'occurrence UV1, mais ne bloquant pas (ou peu) le rayonnement émis par ce même motif 8 sous l'effet d'une autre source de lumière (UV2), de façon à laisser transparaître ce motif 8, comme montré à la figure 5. On ajoutera que cet effet de filtre doit être pris en considération pour ne pas perturber l'équilibre des couleurs obtenu lors du premier test (Fig.4), équilibre auquel il peut du reste contribuer, le cas échéant.Moreover, these inks must each comprise components blocking the passage of the radiation emitted by the pigments of the pattern 8 under the effect of the excitation due to a specific type of radiation, in this case UV1, but not blocking (or little) the radiation emitted by this same pattern 8 under the effect of another light source (UV2), so as to let this pattern 8, as shown in FIG. figure 5 . It should be added that this filter effect must be taken into account in order not to disturb the color balance obtained during the first test ( Fig.4 ), a balance to which he can contribute if necessary.

Les contrefacteurs potentiels se trouvent donc confrontés à une multitude d'effets physiques contradictoires, ce qui rend leur tâche d'autant plus malaisée, pour la plus grande sécurité des usagers.Potential counterfeiters are therefore confronted with a multitude of physical effects contradictory, which makes their task all the more difficult, for the greater safety of users.

Il apparaîtra évident pour l'homme du métier que la présente invention n'est pas limités aux exemples illustrés et décrits ci-dessus. Le dispositif de l'invention peut notamment être fabriqué distinctement du support 6 et être apposé sur celui-ci par un procédé de transfert quelconque, bien connu de l'homme du métier. L'invention comprend chacune des caractéristiques nouvelles ainsi que leur combinaison. La présence de numéros de référence ne peut être considérée comme limitative. L'usage du terme « comprend » ne peut en aucune façon exclure la présence d'autres éléments autres que ceux mentionnés. L'usage de l'article défini « un » pour introduire un élément n'exclut pas la présence d'une pluralité de ces éléments. La présente invention a été décrite en relation avec des modes de réalisations spécifiques, qui ont une valeur purement illustrative et ne doivent pas être considérés comme limitatifs.It will be apparent to those skilled in the art that the present invention is not limited to the examples illustrated and described above. The device of the invention may in particular be manufactured separately from the support 6 and be affixed to it by any transfer method, well known to those skilled in the art. The invention comprises each of the novel features as well as their combination. The presence of reference numbers can not be considered as limiting. The use of the term "includes" in no way excludes the presence of other elements other than those mentioned. The use of the definite article "a" to introduce an element does not exclude the presence of a plurality of these elements. The present invention has been described in relation to specific embodiments, which have a purely illustrative value and should not be considered as limiting.
