Description

Feuille de sécurité comprenant une marque de sécurité iridescente Security sheet with an iridescent security mark
L'invention concerne une feuille de sécurité comprenant une marque de sécurité colorée et présentant un effet iridescent ainsi qu'un document comprenant ladite feuille. Pour se prémunir de contrefaçons ou falsifications de documents de sécurité tels que des moyens de paiement comme les billets de banque, les chèques, ou des documents officiels notamment les documents d'identification tels que des passeports, cartes d'identité, ou des tickets d'entrée à des manifestations culturelles ou sportives ou des tickets de transport ou encore des emballages ou étiquettes comportant un élément d'authentification, on peut utiliser divers moyens de sécurité tels que par exemple des fils de sécurité, hologrammes, filigranes, ou encore des pigments iridescents qui permettent d'authentifier un document par leur effet interférentiel qui crée un changement de couleurs observable sous certains angles. De plus, ces pigments protègent de la photocopie, l'effet iridescent n'étant pas copiable.The invention relates to a security sheet comprising a colored security mark having an iridescent effect and a document comprising said sheet. To guard against counterfeiting or falsification of security documents such as means of payment such as banknotes, checks, or official documents including identification documents such as passports, identity cards, or tickets entry to cultural or sports events or transport tickets or packaging or labels containing an authentication element, various security means can be used, such as security threads, holograms, watermarks, or pigments. iridescent which allow to authenticate a document by their interferential effect which creates a change of colors observable under certain angles. In addition, these pigments protect from photocopying, the iridescent effect not being copiable.
On a notamment décrit dans la demande de brevet européen EP-A-0490825 un papier de sécurité comprenant une application superficielle contenant des pigments iridescents qui n'est pratiquement pas visible en observation directe ( c'est-à-dire face au plan de la surface de l'application sur le papier) qui ne manifeste son effet de coloration que lors d'une observation sous un angle de vue oblique et qui modifie sa coloration lors d'une modification de l'angle de vue, ledit papier étant caractérisé en ce que des zones superficielles diverses, simultanément perceptibles, sont pourvues d'applications qui contiennent des pigments iridescents différents et qui présentent une coloration différente en observation oblique. De préférence ces zones sont des bandes contigϋes. Un tel effet permet qu'un observateur ne voie pas les bandes iridescentes en observation directe mais seulement en observation oblique, le fait de mettre des bandes simultanément perceptibles permet une meilleure perception relative des changements de couleurs de chaque bande en observation oblique. Toutefois le fait que ces bandes soient non visibles en observation directe entraîne qu'un observateur non averti comme « l'homme de la rue » qui veut authentifier un document ne sait pas où repérer ces bandes lorsqu'il observe normalement le document et/ou oublie de faire ce contrôle.European patent application EP-A-0490825 describes in particular a security paper comprising a surface application containing iridescent pigments which is practically not visible under direct observation (that is to say facing the plane of the surface of the application on the paper) which shows its coloring effect only during an observation at an oblique angle of view and which modifies its coloration during a modification of the angle of view, said paper being characterized in that various surface areas, simultaneously perceptible, are provided with applications which contain different iridescent pigments and which have a different color in oblique observation. Preferably these areas are contiguous bands. Such an effect allows an observer not to see the iridescent bands in direct observation but only in oblique observation, the fact of simultaneously perceivable bands allows a better relative perception of the color changes of each band in oblique observation. However, the fact that these bands are not visible in direct observation means that an uninformed observer, such as "the man of the "Street" who wants to authenticate a document does not know where to locate these tapes when he normally observes the document and / or forgets to do this check.
Dans la demande de brevet français FR-A1 -2855640 on a décrit un motif de sécurisation formé d'un premier motif avec des substances à effet interférentiel et d'un autre motif avec des substances réagissant à certaines stimulations donnant une réponse lumineuse à l'œil humain, notamment des substances fluorescentes (réagissant aux rayons UV). Ce moyen de sécurisation nécessite un dispositif pour stimuler le second motif et le rendre visible.In the French patent application FR-A1 -2855640 there is described a security pattern formed of a first pattern with substances having an interference effect and another pattern with substances reacting to certain stimulations giving a luminous response to the human eye, especially fluorescent substances (reactive to UV rays). This securing means requires a device to stimulate the second pattern and make it visible.
La demande FR 2 782 470 décrit une encre iridescente déposée sur un film appliqué à un support et colorée lorsqu'observée par réflexion directe.Application FR 2 782 470 describes an iridescent ink deposited on a film applied to a support and colored when observed by direct reflection.
La demande EP 1 489 151 décrit une encre de sécurité comportant un pigment iridescent présentant deux couleurs différentes par observation en réflexion.The application EP 1 489 151 describes a security ink comprising an iridescent pigment having two different colors by observation in reflection.
Le but de la présente invention est de résoudre les problèmes de l'art antérieur et donc de fournir une feuille de sécurité avec un moyen d'authentification qui soit facilement observable par l'homme de Ia rue tout en présentant un niveau de sécurisation suffisant.The object of the present invention is to solve the problems of the prior art and therefore to provide a security sheet with an authentication means that is easily observable by the man of the street while having a sufficient level of security.
La présente invention propose un moyen de sécurité qui soit à la fois visible en observation normale (de face) avec des effets visibles seulement sous un ou plusieurs autre(s) angle(s) d'observation (à l'oblique) à l'œil nu.The present invention provides a security means that is both visible in normal (face) observation with effects visible only under one or more other (s) angle (s) of observation (at the oblique) to the naked eye.
L'invention présente ainsi l'avantage que l'homme de la rue sait où observer ce moyen et par ailleurs la visibilité de certains effets seulement sous certains angles lui confère un niveau de sécurité suffisant élevé.The invention thus has the advantage that the man of the street knows where to observe this means and also the visibility of certain effects only from certain angles gives it a high enough level of security.
Plus précisément l'invention fournit une feuille de sécurité comprenant une marque de sécurité iridescente observable en surface (de la feuille), qui se caractérise par le fait que cette dite marque comprend au moins une zone présentant un effet iridescent, ladite zone étant colorée en observation normale et à l'œil nu et comprenant des pigments iridescents quasi-incolores en observation normale et présentant un effet iridescent visible seulement en observation à l'oblique.More specifically, the invention provides a security sheet comprising an iridescent safety mark observable at the surface (of the sheet), which is characterized in that said mark comprises at least one zone having an iridescent effect, said zone being colored in normal observation and with the naked eye and comprising almost colorless iridescent pigments in normal observation and having an iridescent effect visible only in oblique observation.
On entend par « observation normale » qu'un observateur regarde la marque ou la zone face au plan respectivement de la marque ou de la zone, soit à environ 90 degrés par rapport au plan respectivement de ladite marque ou de la zone, en lumière blanche (artificielle ou naturelle). Cette observation peut aussi être qualifiée d'observation directe."Normal observation" means that an observer looks at the mark or area in front of the mark or zone plan respectively, or approximately 90 degrees with respect to the plane respectively of said mark or zone, in white light (artificial or natural). This observation can also be described as direct observation.
On entend « par observable à l'œil nu » qu'aucun appareil n'est nécessaire pour stimuler la coloration, un moyen grossissant, comme une loupe, pouvant être utilisé pour pouvoir voir la zone comme dans le cas où la zone serait formée de micro-caractères."By observable with the naked eye" means that no apparatus is necessary to stimulate the coloration, a magnifying medium, such as a magnifying glass, which can be used to be able to see the zone as in the case where the zone is formed of micro-characters.
Dans la présente invention, l'effet iridescent de la au moins dite zone est donc pratiquement invisible en observation normale (de face) et visible qu'en observation à l'oblique c'est-à-dire seulement sous des angles autres qu'à 90 degrés et par ailleurs les pigments iridescents de cette zone n'apparaissent pas intrinsèquement colorés sous observation normale, ils sont intrinsèquement quasi- imperceptibles en observation normale. La zone est rendue perceptible en observation normale par le fait qu'elle est colorée, par exemple par l'ajout d'un colorant.In the present invention, the iridescent effect of the at least said zone is therefore practically invisible in normal observation (of face) and visible only in oblique observation, that is to say only at angles other than At 90 degrees and iridescent pigments of this zone do not appear intrinsically colored under normal observation, they are intrinsically almost imperceptible in normal observation. The zone is made perceptible under normal observation in that it is colored, for example by the addition of a dye.

L'invention sera mieux comprise à l'aide des exemples selon l'invention 1 à 8 suivants et des figures 1 à 10 correspondantes annexées. Les figures 1 , 3 et 5 représentent une vue de face de feuilles de sécurité selon l'invention en observation normale et les figures 2, 4 et 6 en observation oblique, tel qu'indiqué dans la description des exemples. Exemple 1 :The invention will be better understood with the aid of the examples according to the invention 1 to 8 following and corresponding Figures 1 to 10 attached. Figures 1, 3 and 5 show a front view of security sheets according to the invention in normal observation and Figures 2, 4 and 6 in oblique observation, as indicated in the description of the examples. Example 1
Sur une feuille de papier de sécurité, ayant un grammage de 100 g/m2, on imprime par héliogravure une marque de sécurité sous forme de bande, tout en laissant un évidement sous forme de « 10 », par application d'une encre aqueuse comprenant un colorant bleu (Bleu Cartaréne CBR 500 de la société Clariant) et des pigments iridescents à base mica/TiO2 (Iriodin® or 205 de la société Merck) présentant un effet iridescent or, visible seulement en observation oblique. L'encre peut contenir d'autres additifs usuels tels que réticulant, antimousse, liants (liant hydrosoluble tel que du PVA et/ou des liants de type latex comme un polyuréthane), ou encore régulateur de viscosité.On a sheet of security paper, having a basis weight of 100 g / m 2 , a security mark in the form of a strip is printed by gravure printing, while leaving a recess in the form of "10", by application of an aqueous ink comprising a blue dye (Cartarene Blue CBR 500 from Clariant) and iridescent pigments based on mica / TiO2 (Iriodin® or 205 from Merck) having an iridescent gold effect, visible only in oblique observation. The ink may contain other usual additives such as crosslinker, antifoam, binders (water-soluble binder such as PVA and / or latex-type binders such as polyurethane), or viscosity regulator.
L'encre comprend 44,8 g de pigments iridescents et 0,05 g de colorant bleu pour 100 g de la composition d'encre en poids sec. Le dépôt par héliogravure de la composition iridescente est de 12 g/m2, le dépôt en pigments iridescents étant de 5,4 g/m2 ; il y a 0,11 %, en poids sec, de colorant déposé par rapport aux pigments iridescents.The ink comprises 44.8 grams of iridescent pigments and 0.05 grams of blue dye per 100 grams of the dry weight ink composition. The photogravure deposition of the iridescent composition is 12 g / m 2 , the iridescent pigment deposit being 5.4 g / m 2 ; there is 0.11% by dry weight of dye deposited relative to the iridescent pigments.
On obtient ainsi une marque apparaissant uniformément bleue en observation normale (sous un angle de 90 degrés par rapport au plan de la région) avec le motif « 10 » apparaissant en négatif (exempt d'encres) et avec un effet iridescent or, apparaissant seulement en observation oblique.This results in a uniformly blue mark appearing in normal observation (at an angle of 90 degrees to the plane of the region) with the pattern "10" appearing negative (ink-free) and with an iridescent gold effect, appearing only in oblique observation.
Exemple 2 :Example 2
Sur une feuille de papier de sécurité 1 , ayant un grammage de 100 g/m2, on imprime par héliogravure une marque de sécurité 2 en réalisant une première zone 2a sous forme de bande, tout en laissant un évidement sous forme de « 1 », par application d'une encre aqueuse A1 comprenant un colorant vert (vert Cartaréne CVB de la société Clariant) et des pigments iridescents à base mica/TiO2 (Iriodin® Bleu 225 de la société Merck) présentant un effet iridescent bleu visible seulement en observation oblique et en réalisant aussi une seconde zone 2b sous forme de bande, juxtaposée à la première, tout en laissant deux évidements côte à côte sous forme de « 0 » et à côté du « 1 » de la zone 2a, par application d'une encre aqueuse B1 comprenant ledit colorant vert et des pigments iridescents à base mica/TiO2 (Iriodin® Lilac 219 de la société Merck) présentant un effet iridescent violet visible seulement en observation oblique . Les pigments iridescents eux-mêmes sont quasiment incolores en observation normale. Les encres peuvent contenir d'autres additifs usuels tels que réticulant, antimousse, liants (liant hydrosoluble tel que du PVA et/ou des liants de type latex comme un polyuréthane), régulateur de viscosité. Chacune des encres A1 et B1 comprend 44,8 g de pigments iridescents et 0,03 g de colorant vert pour 100 g de la composition d'encre en poids sec. La teinte des encres a été ajustée par mesures colorimétriques et par mesures de brillance Gardner. Le dépôt par héliogravure des compositions iridescentes A1 et B1 est de 12 g/m2 (par composition) sur la feuille, le dépôt en pigments iridescents est de 5,4 g/m2 et celui en colorant est de 0,005g/m2 ; il y a donc environ 0,1%, en poids sec, de colorant déposé par rapport aux pigments iridescents.On a sheet of security paper 1, having a grammage of 100 g / m 2 , a security mark 2 is printed by gravure printing, producing a first zone 2a in the form of a strip, while leaving a recess in the form of "1". by application of an aqueous ink A1 comprising a green dye (Cartarene green CVB from Clariant) and iridescent pigments based on mica / TiO 2 (Iriodin® Blue 225 from Merck) having a blue iridescent effect visible only in oblique observation and also realizing a second zone 2b in the form of a strip, juxtaposed with the first, while leaving two recesses side by side in the form of "0" and next to the "1" of the zone 2a, by application of an aqueous ink B1 comprising said green dye and iridescent pigments based on mica / TiO 2 (Iriodin® Lilac 219 from Merck) having an iridescent violet effect visible only in oblique observation. The iridescent pigments themselves are almost colorless in normal observation. The inks may contain other usual additives such as crosslinker, antifoam, binders (water-soluble binder such as PVA and / or latex-type binders such as polyurethane), viscosity regulator. Each of the A1 and B1 inks comprises 44.8 g of iridescent pigments and 0.03 g of green dye per 100 g of the dry weight ink composition. The color of the inks was adjusted by colorimetric measurements and Gardner gloss measurements. The photogravure deposition of the iridescent compositions A1 and B1 is 12 g / m 2 (per composition) on the sheet, the deposit in iridescent pigments is 5.4 g / m 2 and that in dye is 0.005 g / m 2 ; there is therefore about 0.1%, by dry weight, of dye deposited relative to the iridescent pigments.
Les données colorimétriques pour la marque faites des deux bandes sont les suivantes :The colorimetric data for the mark made of the two bands are as follows:
On obtient ainsi une marque composée de deux zones juxtaposées (2a,2b), ladite marque apparaissant uniformément verte en observation normale (sous un angle de 90 degrés par rapport au plan de la région) avec le motif « 100 » apparaissant en négatif (exempt d'encres) comme indiqué sur la figure 1 et avec des effets iridescents apparaissant seulement en observation oblique et différents d'une zone à l'autre comme indiqué sur la figure 2, la zone 2a a un effet bleu et la zone 2b a un effet violet. Exemple 3 :A mark consisting of two juxtaposed zones (2a, 2b) is thus obtained, said mark appearing uniformly green in normal observation (at an angle of 90 degrees relative to the plane of the region) with the "100" pattern appearing in negative (free of inks) as shown in Figure 1 and with iridescent effects appearing only in oblique observation and different from one area to another as shown in Figure 2, the area 2a has a blue effect and the area 2b has a purple effect. Example 3
Sur une feuille de papier de sécurité 1 , on imprime par sérigraphie une marque de sécurité 2 en réalisant une première zone 2a sous forme de bande par application d'une encre aqueuse A2 comprenant un colorant rouge et des pigments iridescents à base mica/TiO2 (Iriodin® 235 de la société Merck) présentant un effet iridescent vert visible seulement en observation oblique et on réalise aussi une seconde zone 2b imbriquée dans la première, sous forme d'un hexagone comprenant deux évidements sous forme de « A » et « W » en appliquant une encre aqueuse B2 comprenant ledit colorant rouge et des pigments iridescents à base mica/TiO2 (Iriodin® 205 de la société Merck) présentant un effet iridescent or visible seulement en observation oblique. Les pigments iridescents eux-mêmes sont quasiment incolores en observation normale. Comme à l'exemple 2, les encres A2 et B2 ont la même teinte, cette teinte, est ajustée selon chaque encre en fonction des autres ingrédients et notamment des pigments iridescents. Les encres peuvent contenir d'autres additifs usuels tels que réticulant, antimousse, liants (liant hydrosoluble tel que du PVA et/ou des liants de type latex comme un polyuréthane), régulateur de viscosité et glycérine. Chacune des encres A2 et B2 comprend 28,4 g de pigments iridescents et 0,03 g de colorant rouge pour 100 g de la composition d'encre en poids sec. La teinte des encres a été ajustée par mesures colorimétriques et par mesures de brillance Gardner. Le dépôt par sérigraphie des compositions iridescentes A2 et B2 est de 12 g/m2 (par composition), le dépôt en pigments iridescents étant de 3,45 g/m2 et celui en colorant de 0,0031 g/m2, il y a donc environ 0,091%, en poids sec, de colorant déposé par rapport aux pigments iridescents.On a sheet of security paper 1, a security mark 2 is printed by serigraphy by producing a first zone 2a in the form of a strip by application of an aqueous ink A2 comprising a red dye and iridescent pigments based on mica / TiO 2. (Iriodin® 235 from Merck) having a green iridescent effect visible only in oblique observation and a second zone 2b imbricated in the first is also formed in the form of a hexagon comprising two recesses in the form of "A" and "W". By applying an aqueous ink B2 comprising said red dye and iridescent pigments based on mica / TiO 2 (Iriodin® 205 from Merck) having an iridescent gold effect visible only in oblique observation. The iridescent pigments themselves are almost colorless in normal observation. As in Example 2, the inks A2 and B2 have the same hue, this hue, is adjusted according to each ink according to other ingredients including iridescent pigments. The inks may contain other usual additives such as crosslinker, antifoam, binders (water-soluble binder such as PVA and / or latex-type binders such as polyurethane), viscosity regulator and glycerin. Each of the inks A2 and B2 comprises 28.4 grams of iridescent pigments and 0.03 grams of red dye per 100 grams of the dry weight ink composition. The color of the inks was adjusted by colorimetric measurements and Gardner gloss measurements. The silkscreen deposition of the iridescent compositions A2 and B2 is 12 g / m 2 (per composition), the deposit in iridescent pigments being 3.45 g / m 2 and the dyeing of 0.0031 g / m 2 there is therefore about 0.091%, by dry weight, of dye deposited relative to the iridescent pigments.
On obtient ainsi une marque composée de deux zones imbriquées (2a, 2b), ladite marque apparaissant uniformément rouge en observation normale avec le motif « AW» apparaissant en négatif comme indiqué sur la figure 3 et avec des effets iridescents visibles seulement en observation oblique et différents selon les zones comme indiqué sur la figure 4 faisant apparaître l'hexagone de la zone 2b dans la bande 2a. Exemple 4 :A mark composed of two nested zones (2a, 2b) is thus obtained, said mark appearing uniformly red in normal observation with the pattern "AW" appearing in negative as indicated in FIG. 3 and with iridescent effects visible only in oblique observation and different according to the zones as shown in Figure 4 showing the hexagon zone 2b in the band 2a. Example 4
On reprend les encres de l'exemple 2 auxquelles on ajoute à chacune des encres, un composé fluorescent ; à l'encre A1 on ajoute un composé fluorescent rouge, à l'encre B1 on ajoute un composé fluorescent bleu. Comme à l'exemple 2, on réalise une marque de sécurité sur une feuille. La marque apparaît rouge dans la zone 2a et bleue dans la zone 2b sous illumination UV.We recover the inks of Example 2 to which is added to each of the inks, a fluorescent compound; in ink A1, a red fluorescent compound is added, in ink B1 a blue fluorescent compound is added. As in Example 2, a security mark is made on a sheet. The mark appears red in zone 2a and blue in zone 2b under UV illumination.
Exemple 5 :Example 5
On reprend les encres de l'exemple 3 auxquelles on ajoute à chacune des encres, un composé fluorescent ; à l'encre A2 on ajoute un composé fluorescent rouge, à l'encre B2 on ajoute un composé fluorescent bleu. Comme à l'exemple 3, on réalise une marque de sécurité sur une feuille. La marque apparaît rouge dans la zone 2a et bleue dans la zone 2b sous illumination UV.We recover the inks of Example 3 to which is added to each of the inks, a fluorescent compound; in ink A2, a red fluorescent compound is added, in ink B2 a blue fluorescent compound is added. As in Example 3, a security mark is made on a sheet. The mark appears red in zone 2a and blue in zone 2b under UV illumination.
Exemple 6 :Example 6
Sur une feuille de papier de sécurité 1 , on imprime par héliogravure une marque de sécurité 2 en réalisant une première zone 2a sous forme de bande par application d'une encre A5 comprenant un colorant vert et des pigments iridescents à base mica/TiO2 (Iriodin® 205 de la société Merck) présentant un effet iridescent or, visible seulement en observation oblique et on réalise aussi une seconde zone 2b juxtaposée à la première, sous forme d'un hexagone comprenant deux évidements sous forme de « A » et « W » en appliquant une encre B5 comprenant un colorant bleu et les mêmes pigments iridescents que pour l'encre A5. Les pigments iridescents eux-mêmes sont quasiment incolores en observation normale. Les encres A5 et B5 ont donc une teinte différente.On a sheet of security paper 1, a security mark 2 is printed by rotogravure by producing a first zone 2a in the form of a strip by application of an ink A5 comprising a green dye and iridescent pigments based on mica / TiO 2 ( Iriodin® 205 from Merck) having an iridescent gold effect, visible only in oblique observation, and a second zone 2b juxtaposed with the first, in the form of a hexagon comprising two recesses in the form of "A" and "W". By applying an ink B5 comprising a blue dye and the same iridescent pigments as for the ink A5. The iridescent pigments themselves are almost colorless in normal observation. Inks A5 and B5 therefore have a different hue.
On obtient ainsi une marque composée de deux zones imbriquées, ladite région apparaissant sous forme de deux zones de teintes différentes en observation normale, l'une verte et l'autre bleue sous forme d'hexagone avec le motif « AW» apparaissant en négatif comme indiqué sur la figure 5 et avec des effets iridescents visibles seulement en observation oblique et semblables dans les deux zones, l'hexagone ne se distinguant plus comme indiqué sur la figure 6. Exemple 7 :A mark composed of two nested zones is thus obtained, said region appearing in the form of two zones of different hues in normal observation, one green and the other blue in the form of a hexagon with the motif "AW" appearing in negative as indicated in FIG. 5 and with iridescent effects visible only in oblique observation and similar in the two zones, the hexagon being no longer distinguishable as indicated in FIG. Example 7
Sur une feuille de papier de sécurité 1 , on imprime par héliogravure une marque de sécurité 2 sous forme de bande, en réalisant une première zone 2a sous forme d'une bande comprenant des évidements sous forme de "100" et des évidements sous forme de "AW", par application d'une encre comprenant un colorant vert (vert Catarène de la société Clariant) et des pigments iridescents à base mica/TiO2 (Iriodin ® Lilac 219 de la société Merck) présentant un effet violet visible seulement en observation oblique. On réalise également une seconde zone 2b sous forme d'un motif "100" par application d'une encre comprenant un même colorant vert (vert Catarène de la société Clariant) et des pigments iridescents à base mica/TiO2 (Iriodin ® 225 de la société Merck) présentant un effet bleu visible seulement en observation oblique, lesdits motifs "100" étant appliqués au repère par rapport aux évidements sous forme de "100" de la première zone 2a, de façon à coïncider. Les pigments iridescents des zones 2a et 2b sont quasiment incolores en observation normale.On a sheet of security paper 1, a security mark 2 in the form of a strip is printed by rotogravure, producing a first zone 2a in the form of a strip comprising recesses in the form of "100" and recesses in the form of "AW", by application of an ink comprising a green dye (catarene green from Clariant) and iridescent pigments based on mica / TiO 2 (Iriodin® Lilac 219 from Merck) having a visible violet effect only under observation oblique. A second zone 2b is also produced in the form of a "100" pattern by applying an ink comprising the same green dye (Catarene green from Clariant) and iridescent pigments based on mica / TiO 2 (Iriodin® 225 from Merck) having a visible blue effect only in oblique observation, said patterns "100" being applied to the reference relative to the recesses in the form of "100" of the first zone 2a, so as to coincide. The iridescent pigments of zones 2a and 2b are almost colorless in normal observation.
On obtient ainsi, en observation normale, une marque apparaissant comme une bande verte avec des évidements "100", comme indiqué à la figure 7. En observation oblique, on obtient une bande présentant un effet violet, avec des évidements (exempts d'encre) en forme de "AW" et des motifs "100" présentant un effet bleu, comme indiqué à la figure 8.This gives, in normal observation, a mark appearing as a green band with recesses "100", as shown in Figure 7. In oblique observation, we obtain a band with a purple effect, with recesses (ink-free ) in the form of "AW" and patterns "100" having a blue effect, as shown in Figure 8.
Exemple 8 :Example 8
Sur une feuille de papier de sécurité 1 , on imprime par héliogravure une région de sécurité 2 sous forme de bande, en réalisant une première zone 2a sous forme d'une bande comprenant des évidements sous forme d'hexagone, par application d'une encre comprenant un colorant vert (vert Catarène de la société Clariant) et des pigments iridescents à base mica/TiO2 (Iriodin ® Lilac 219 de la société Merck) présentant un effet violet visible seulement en observation oblique. On réalise également une seconde zone 2b, en appliquant au sein de chaque évidement en forme d'hexagone un motif "AW" en une encre comprenant un colorant vert (vert Catarène de la société Clariant) et des pigments iridescents à base mica/TiO2 (Iriodin ® 225 de la société Merck) présentant un effet bleu visible seulement en observation oblique. Les pigments iridescents des zones 2a et 2b sont quasiment incolores en observation normale.On a sheet of security paper 1, a security region 2 in the form of a strip is printed by rotogravure, by producing a first zone 2a in the form of a strip comprising recesses in the form of a hexagon, by applying an ink comprising a green dye (catarene green from Clariant) and iridescent pigments based on mica / TiO 2 (Iriodin® Lilac 219 from Merck) having a visible violet effect only in oblique observation. A second zone 2b is also produced by applying, within each hexagon-shaped recess, an "AW" pattern in an ink comprising a green dye (Catarene green of the Clariant company) and iridescent pigments based on mica / TiO 2. (Iriodin ® 225 from Merck) with a visible blue effect only in oblique observation. The iridescent pigments of zones 2a and 2b are almost colorless in normal observation.
On obtient ainsi, en observation normale, une marque apparaissant comme une bande verte avec des évidements (exempts d'encre) en forme d'hexagone, chaque hexagone comprenant un motif "AW" de la même couleur que la bande, comme indiqué à la figure 9. En observation oblique, on obtient une bande présentant un effet violet, avec des évidements (exempts d'encre) en forme d'hexagone et des motifs "AW" présentant un effet bleu, comme indiqué à la figure 10. This gives, in normal observation, a mark appearing as a green band with recesses (ink-free) in the form of a hexagon, each hexagon comprising a pattern "AW" of the same color as the band, as indicated in FIG. Figure 9. In oblique observation, a band with a violet effect is obtained, with hexagon-shaped (ink-free) recesses and "AW" patterns with a blue effect, as shown in Figure 10.
