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

Campo de la presente invención Field of the present invention

La presente invención se refiere a dispositivos destinados a disuadir de la falsificación de documentos fiduciarios (certificados, billetes de banco, etc.) o documentos de seguridad, tales como documentos de identidad, tarjetas de acceso a zonas restringidas, tarjetas de crédito, etc. The present invention relates to devices intended to deter the falsification of fiduciary documents (certificates, banknotes, etc.) or security documents, such as identity documents, access cards to restricted areas, credit cards, etc.

Estado de la técnica State of the art

Se conocen, en particular, a partir de las patentes EP 0 265 323 y GB 2 189 800, unos documentos que presentan unas zonas impresas que, cuando se exponen a radiaciones UV, producen, mediante la utilización de pigmentos fluorescentes, dos zonas de colores contrastados (por ejemplo, verde y rojo). El problema es que los usuarios generalmente se limitan a verificar si existe fluorescencia o no, sin autentificar los propios colores. Se trata de un fallo que pueden aprovechar los falsificadores profesionales. Particularly known from EP 0 265 323 and GB 2 189 800, documents that have printed areas that, when exposed to UV radiation, produce, through the use of fluorescent pigments, two colored areas contrasted (for example, green and red). The problem is that users generally limit themselves to checking whether there is fluorescence or not, without authenticating the colors themselves. This is a bug that professional counterfeiters can take advantage of.

Se conoce a partir del documento EP-1 179 808 un procedimiento de identificación más precisa de documentos fraudulentos. Gracias a la utilización de pigmentos fluorescentes con unas características cuidadosamente ajustadas, cuando un documento realizado con seguridad de este modo se somete sucesivamente a dos fuentes de UV con longitudes de onda distintas, se obtienen unos patrones similares o distintos de colores, lo que permite la autentificación. A more precise identification procedure for fraudulent documents is known from EP-1 179 808. Thanks to the use of fluorescent pigments with carefully adjusted characteristics, when a document made with security in this way is successively subjected to two UV sources with different wavelengths, similar or different color patterns are obtained, which allows authentication

El documento FR-2 762 545 se refiere a un documento fiduciario o similar, tal como un billete de banco, pasaporte, documento de identidad, tarjeta de crédito, que comprende un medio en el que se disponen impresiones de seguridad. Las impresiones de seguridad comprende: una primera impresión realizada con tinta de un primer color invisible a simple vista, pero fluorescente o fosforescente; una segunda impresión que cubre la primera y que se realiza con tinta de un segundo color visible o invisible a simple vista, pero fluorescente o fosforescente, realizándose la segunda impresión para que difumine la primera impresión, de tal modo que con luz neutra o iluminación ultravioleta, únicamente dicha segunda impresión es visible, mientras que la primera impresión se revela únicamente en con iluminación ultravioleta y a través de un filtro del mismo color que el de la primera impresión. En esta técnica, no se requiere una equivalencia perfecta de colores, muy difícil de obtener por un posible falsificador con tintas distintas. Es necesario además disponer de un filtro particular para verificar posibles billetes falsificados. Document FR-2 762 545 refers to a fiduciary document or the like, such as a banknote, passport, identity document, credit card, comprising a means in which security impressions are arranged. Security prints include: a first print made with a first color ink invisible to the naked eye, but fluorescent or phosphorescent; a second impression that covers the first and that is made with ink of a second color visible or invisible to the naked eye, but fluorescent or phosphorescent, the second impression being made to blur the first impression, so that with neutral light or ultraviolet lighting , only said second impression is visible, while the first impression is revealed only in ultraviolet illumination and through a filter of the same color as that of the first impression. In this technique, a perfect equivalence of colors is not required, very difficult to obtain for a possible forger with different inks. It is also necessary to have a particular filter to verify possible counterfeit bills.

Sumario de la presente invención Summary of the present invention

Un objetivo de la presente invención es permitir una comprobación fácil y fiable de la autentificación de un documento. An objective of the present invention is to allow an easy and reliable verification of the authentication of a document.

Un objetivo adicional de la presente invención es utilizar una tecnología fácil de utilizar pero difícil o incluso imposible de reproducir para los falsificadores potenciales. A further objective of the present invention is to use a technology easy to use but difficult or even impossible to reproduce for potential counterfeiters.

El objetivo de la presente invención es un dispositivo de autentificación de documentos, presentando dicho documento por lo menos dos zonas yuxtapuestas, impresa cada una de las mismas con una tinta que comprende pigmentos fluorescentes. La composición de dichas tintas es tal que cuando el documento está expuesto a un primero de dos tipos de radiación UV con una longitud de onda particular, las dos zonas aparecen con un color idéntico a simple vista, mientras que cuando el documento está expuesto a un segundo de dos tipos de radiación UV (con otra longitud de onda particular), aparecen con colores distintos. En dicho dispositivo, dichas por lo menos dos zonas yuxtapuestas cubren cada una de las mismas, por lo menos parcialmente, por lo menos una tercera zona, impresa asimismo utilizando una tinta que comprende pigmentos fluorescentes. La composición de las tintas de dichas por lo menos dos zonas es tal que constituyen un filtro opaco bajo uno de los dos tipos de radiación UV para la radiación emitida hacia, o retransmitida por, la tercera zona, de tal modo que dicha por lo menos tercera zona permanece invisible. Dicho efecto de filtro desaparece o se atenúa cuando el documento se expone a los otros dos tipos de radiación UV, de tal modo que la tercera zona aparece en dicho momento con un color distinto de las por lo menos otras dos zonas. The object of the present invention is a document authentication device, said document having at least two juxtaposed areas, each printed with an ink comprising fluorescent pigments. The composition of said inks is such that when the document is exposed to a first of two types of UV radiation with a particular wavelength, the two zones appear with an identical color to the naked eye, while when the document is exposed to a second of two types of UV radiation (with another particular wavelength), they appear in different colors. In said device, said at least two juxtaposed zones cover each of them, at least partially, at least a third zone, also printed using an ink comprising fluorescent pigments. The composition of the inks of said at least two zones is such that they constitute an opaque filter under one of the two types of UV radiation for the radiation emitted towards, or retransmitted by, the third zone, such that said at least Third zone remains invisible. Said filter effect disappears or is attenuated when the document is exposed to the other two types of UV radiation, so that the third zone appears at that time with a color different from those of at least two other zones.

En una forma de realización preferida, los patrones constituidos por las tres zonas no aparecen separadamente de su fondo a la luz ambiente. In a preferred embodiment, the patterns constituted by the three zones do not appear separately from their background in ambient light.

En una forma de realización ventajosa, la composición de las tintas de por lo menos dos zonas es de tal modo que, bajo primer tipo de radiación UV, constituyen un filtro opaco para la parte de aquella radiación que puede alcanzar la por lo menos una tercera zona. In an advantageous embodiment, the composition of the inks of at least two zones is such that, under the first type of UV radiation, they constitute an opaque filter for the part of that radiation that can reach at least a third zone.

El dispositivo de autentificación de la presente invención comprende ventajosamente por lo menos dos terceras zonas. The authentication device of the present invention advantageously comprises at least two third zones.

Un objetivo adicional de la presente invención es un documento de seguridad que comprenda por lo menos un dispositivo de autentificación tal como se ha descrito anteriormente. A further objective of the present invention is a security document comprising at least one authentication device as described above.

Descripción detallada de las formas de realización particulares Detailed description of the particular embodiments

La figura 1 representa, en sección, y con los espesores muy desproporcionados, la forma de realización general del dispositivo 1 de la presente invención. Dos tramas contiguas 2, 4 impresas utilizando tintas con una composición distinta, comprendiendo cada una de las mismas pigmentos fluorescentes, se aplican a un soporte apto 6. Un ejemplo de composición para el color del motivo 2 es [rojo bi-fluo amarillo/naranja, SICPA rojo amarillento 20, SICPA blanco transparente 20, SICPA bi-fluo amarillo/naranja 60] y para el motivo 4 [Rojo fluo amarillo, SICPA rojo amarillento 20.0, SICPA blanco transparente 75.0, SICPA incoloro fluo amarillo 1.5, SICPA incoloro fluo amarillo 2.0, SICPA incoloro fluo rojo 1.5]. Dicho soporte 6 puede ser un papel destinado a la fabricación de papel moneda, documentos auténticos, plástico, etc. Dichas tramas 2, 4 cubren (completamente en el ejemplo) un tercer motivo 8, impreso utilizando una tinta con una composición distinta de la cual constituye las otras dos tramas, que comprende asimismo pigmentos fluorescentes. En este caso, se puede utilizar la composición siguiente: Blanco fluo rojo, blanco de cobertura química solar 50, SICPA invisible fluo rojo 50. Si se expone a la luz ambiente, tal como en la figura 2, el dispositivo 1 aparece con cualquier color (color A, representado por puntos), por ejemplo en la forma de parche coloreado. El dispositivo se puede ocultar asimismo en un motivo abstracto (véase la figura 3) (en este caso asimismo del color A) o en cualquier otro motivo, impreso en el soporte 6. Figure 1 represents, in section, and with very disproportionate thicknesses, the general embodiment of the device 1 of the present invention. Two adjacent frames 2, 4 printed using inks with a different composition, each of the same fluorescent pigments comprising, are applied to a suitable support 6. An example of a composition for the color of motif 2 is [yellow / orange bi-fluo red , SICPA yellowish red 20, SICPA transparent white 20, SICPA bi-fluo yellow / orange 60] and for motif 4 [Yellow fluo red, SICPA yellowish red 20.0, SICPA transparent white 75.0, SICPA colorless yellow fluo 1.5, SICPA colorless yellow fluo 2.0, SICPA colorless red fluo 1.5]. Said support 6 can be a paper intended for the manufacture of paper money, authentic documents, plastic, etc. Said frames 2, 4 cover (completely in the example) a third motif 8, printed using an ink with a different composition from which constitutes the other two frames, which also comprises fluorescent pigments. In this case, the following composition can be used: Red fluo white, solar chemical coverage white 50, SICPA invisible fluo red 50. If exposed to ambient light, as in Figure 2, device 1 appears in any color (color A, represented by dots), for example in the form of a colored patch. The device can also be hidden in an abstract motif (see figure 3) (in this case also of color A) or in any other motif, printed on the holder 6.

La figura 4 representa lo que sucede cuando un documento provisto de un dispositivo según la presente invención se somete a la radiación (UV1) de una lámpara ultravioleta 10 que emite en un primer intervalo de longitudes de onda: las dos tramas 2, 4 aparecen a simple vista con un color fosforescente idéntico B (en este caso representado simbólicamente por las líneas de sombreado horizontal), el tercer motivo permanece invisible. Figure 4 represents what happens when a document provided with a device according to the present invention is subjected to the radiation (UV1) of an ultraviolet lamp 10 that emits in a first range of wavelengths: the two frames 2, 4 appear at At a glance with an identical phosphorescent color B (in this case symbolically represented by horizontal shading lines), the third motif remains invisible.

La figura 5 representa lo que sucede cuando el mismo documento se somete a la radiación (UV2) de una segunda lámpara ultravioleta 10 que emite en un segundo intervalo de longitudes de onda: cada una de los motivos 2, 4 aparece con un color fosforescente distinto (colores representados por las líneas de sombreado oblicuas izquierda o derecha). El tercer motivo aparece con un tercer color (líneas de sombreado verticales). La transición de un parche de color uniforme a tres zonas de colores distintos (y preferentemente contrastando intensamente) constituye una prueba evidente para el usuario de la autenticidad del documento, mientras que la tecnología necesaria para la obtener los mismos efectos se encuentra totalmente fuera del alcance de incluso un falsificador profesional. Figure 5 represents what happens when the same document is subjected to the radiation (UV2) of a second ultraviolet lamp 10 that emits in a second wavelength range: each of the motifs 2, 4 appears with a different phosphorescent color (colors represented by the left or right oblique shading lines). The third motif appears with a third color (vertical shading lines). The transition from a patch of uniform color to three zones of different colors (and preferably intensely contrasting) constitutes an evident proof for the user of the authenticity of the document, while the technology necessary to obtain the same effects is completely out of reach of even a professional forger.

Para obtener el efecto pretendido, se utiliza una tecnología que es relativamente simple en de por sí, pero compleja de aplicar: To obtain the intended effect, a technology is used that is relatively simple in itself, but complex to apply:

En primer lugar, resulta necesario ajustar la composición de las tintas que constituyen los motivos 1 y 2 para obtener el mismo color en la radiación UV1, algo que resulta una tarea difícil para cualquier falsificador. First of all, it is necessary to adjust the composition of the inks that constitute motifs 1 and 2 to obtain the same color in UV1 radiation, something that is a difficult task for any forger.

Además, dichas tintas deben comprender elementos que bloqueen el paso de las radiaciones emitidas por los pigmentos con el motivo 8 debido al efecto de la excitación como consecuencia de un tipo concreto de radiación, en este caso UV1, pero que bloqueen poco o nada las radiaciones emitidas por el mismo motivo 8 debido al efecto de otra fuente lumínica (UV2), de tal modo que se permita observar dicho motivo 8, tal como se representa en la figura In addition, said inks must comprise elements that block the passage of the radiations emitted by the pigments with the motif 8 due to the effect of the excitation as a result of a specific type of radiation, in this case UV1, but that block little or nothing radiation emitted for the same reason 8 due to the effect of another light source (UV2), so that it is possible to observe said reason 8, as shown in the figure

5. Además, se ha de tener en cuenta dicho efecto de filtro a fin de no interferir con el equilibrio de los colores obtenidos durante la primera prueba (véase, la figura 4), a cuyo equilibrio se puede contribuir adicionalmente, si procede. 5. In addition, this filter effect has to be taken into account in order not to interfere with the balance of the colors obtained during the first test (see Figure 4), to which balance can be contributed additionally, if appropriate.

Los falsificadores potenciales se encuentran, por lo tanto, ante una pluralidad de efectos físicos contradictorios, lo que dificulta su tarea, para mayor seguridad de los usuarios. Potential counterfeiters are, therefore, faced with a plurality of contradictory physical effects, which makes their task difficult, for greater user safety.

Una forma de realización adicional del sistema de la presente invención se representa en las figuras 6 y 7. En el caso representado en la figura 6, las características de los pigmentos se han seleccionado de tal modo que cuando las zonas 1 y 2 aparecen con un color idéntico, a diferencia de lo que ocurre en la figura 4, los pigmentos bloqueen A further embodiment of the system of the present invention is represented in Figures 6 and 7. In the case represented in Figure 6, the characteristics of the pigments have been selected such that when zones 1 and 2 appear with a identical color, unlike what happens in figure 4, the pigments block

5 poco o nada las radiaciones emitidas por el motivo 8 debido al efecto de la fuente lumínica (UV2), de tal modo que se pueda observar dicho motivo 8. Se obtienen, por lo tanto, dos zonas concéntricas de diferentes colores. Por otro lado, en este caso se han seleccionado las características, de tal modo que bajo la iluminación de tipo UV1 el parche central 8 desaparece repentinamente, bloqueándose sus radiaciones, mientras que los colores de las zonas 2 y 4 se vuelven distintos (véase la figura 7). 5 little or nothing radiation emitted by motif 8 due to the effect of the light source (UV2), so that motive 8 can be observed. Therefore, two concentric zones of different colors are obtained. On the other hand, in this case the characteristics have been selected, so that under UV1 illumination the central patch 8 suddenly disappears, blocking its radiations, while the colors of zones 2 and 4 become different (see figure 7).

10 Resultará evidente para los expertos en la materia que la presente invención no se limita a los ejemplos ilustrados y descritos anteriormente. El dispositivo de la presente invención se puede realizar, en particular, por separado del soporte 6 y aplicarse a este último mediante cualquier procedimiento de transferencia conocido por los expertos en la materia.
