Abstract
Description
L'invention concerne une feuille de sécurité et plus particulièrement un papier pour page de garde de passeport.The invention relates to a security sheet and more particularly to a paper for a passport cover page.
Les passeports sont constitués en général d'une couverture en papier fort, du genre simili cuir, et de feuillets. Les feuillets sont réalisés à partir de papier de sécurité pouvant comporter des filigranes, des fibres ou des planchettes colorées ou fluorescentes, des agents chimiques d'infalsification. Les feuillets et la couverture sont le plus souvent solidarisés par le milieu à l'aide d'une couture avec des fils qui peuvent être fluorescents. Les mentions importantes du passeport, à savoir le nom et le prénom du titulaire, sa nationalité, ses date et lieu de naissance, son adresse, sa photographie sont portées sur une face d'un feuillet et recouvertes d'une feuille de matière synthétique transparente, collée sur la face du feuillet de façon à ne pouvoir être arrachée sans détruire le feuillet auquel elle est solidarisée.Passports generally consist of a strong paper cover, of the kind imitation leather, and sheets. The sheets are made from security paper which may include watermarks, fibers or colored or fluorescent boards, chemical agents for falsification. The sheets and the cover are most often joined together in the middle using a seam with threads which can be fluorescent. The important details of the passport, namely the name and first name of the holder, his nationality, his date and place of birth, his address, his photograph are carried on one side of a sheet and covered with a sheet of transparent synthetic material. , glued to the face of the sheet so that it cannot be torn off without destroying the sheet to which it is secured.
Cependant, bien que ces passeports, ainsi constitués, présentent une bonne sécurité contre les contrefaçons ou les falsifications, on cherche encore à améliorer la sécurité.However, although these passports, thus constituted, offer good security against counterfeits or falsifications, efforts are still being made to improve security.
Un premier but de l'invention est de fournir un papier de sécurité qui puisse être solidarisé avec la face interne de la couverture du passeport lors de la fabrication de celui-ci et qui ne puisse pas être désolidarisé postérieurement.A first object of the invention is to provide a security paper which can be secured to the internal face of the cover of the passport during the manufacture of the latter and which cannot be separated later.
Un second but de l'invention est de fournir un papier de sécurité mentionné ci-dessus qui soit en outre capable de supporter la couture des feuillets à l'aide d'un fil.A second object of the invention is to provide a security paper mentioned above which is also capable of supporting the sewing of the sheets using a thread.
Un troisième but de l'invention est de fournir un papier de sécurité mentionné ci-dessus qui soit en outre imprimable.A third object of the invention is to provide a security paper mentioned above which is also printable.
A cet effet, l'invention concerne une feuille de papier comportant une zone mince d'épaisseur inférieure à 80 micromètres et une zone épaisse d'épaisseur supérieure à 50 % de l'épaisseur de la zone mince.To this end, the invention relates to a sheet of paper comprising a thin area of thickness less than 80 micrometers and a thick area of thickness greater than 50% of the thickness of the thin area.
De préférence, la feuille de papier comporte une zone ayant une épaisseur de 60 micromètres et une zone épaisse ayant une épaisseur de 90 micromètres.Preferably, the sheet of paper has an area having a thickness of 60 micrometers and a thick area having a thickness of 90 micrometers.
Selon un mode de réalisation, la feuille est rectangulaire et comporte une zone épaisse médiane située transversalement. On peut aussi prévoir que la feuille comporte une zone épaisse le long des bords et mince au centre. La feuille peut aussi comporter une zone mince rectangulaire dans un coin de la feuille.According to one embodiment, the sheet is rectangular and has a thick central area located transversely. It can also be provided that the sheet has a thick zone along the edges and thin in the center. The sheet may also have a thin rectangular area in a corner of the sheet.
De préférence, la zone médiane est un filigrane sombre. Ainsi, la feuille selon l'invention est suffisamment mince pour empêcher le grattage des mentions imprimées ou écrites sur la feuille et pour empêcher le décollage de la feuille lorsqu'elle est solidarisée à la face interne d'une couverture de passeport. En outre, la zone médiane plus épaisse permet de supporter la couture à l'aide d'un fil qui solidarise la couverture et les feuillets du passeport.Preferably, the middle area is a dark watermark. Thus, the sheet according to the invention is thin enough to prevent scratching of the imprints printed or written on the sheet and to prevent the sheet from taking off when it is secured to the internal face of a passport cover. In addition, the thicker central zone allows the seam to be supported with a thread which secures the cover and the passport sheets.
Selon un mode de réalisation préféré de l'invention, la feuille de papier est couchée de façon à l'opacifier et à améliorer l'imprimabilité de la feuille. La feuille est couchée de préférence à l'aide d'une composition aqueuse décrite et revendiquée dans la demande de brevet français 90 13310. Par exemple on peut coucher la feuille avec une composition aqueuse comprenant un liant tel qu'une dispersion aqueuse de polyuréthane, une charge telle que de kaolin et un agent plastifiant, tel que la glycérine. La couche peut être déposée sur au moins une face de la feuille.According to a preferred embodiment of the invention, the sheet of paper is coated so as to cloud it and improve the printability of the sheet. The sheet is preferably coated using an aqueous composition described and claimed in French patent application 90 13310. For example, the sheet can be coated with an aqueous composition comprising a binder such as an aqueous polyurethane dispersion, a filler such as kaolin and a plasticizing agent, such as glycerin. The layer can be deposited on at least one face of the sheet.
La description suivante, en regard des dessins annexés, permettra de comprendre comment l'invention peut être mise en pratique.The following description, with reference to the accompanying drawings, will make it possible to understand how the invention can be put into practice.
La figure 1 est une vue en perspective d'un passeport comportant la feuille selon l'invention.Figure 1 is a perspective view of a passport comprising the sheet according to the invention.
La figure 2 représente une feuille selon l'invention.FIG. 2 represents a sheet according to the invention.
La figure 3 représente la feuille de la figure 2 en coupe.Figure 3 shows the sheet of Figure 2 in section.
Sur la figure 1, on a représenté un passeport 1 comportant une couverture 2 et des feuillets 3.
Les feuillets 3 et la couverture sont solidarisés à l'aide d'une couture 4 formée par un fil 5. Les feuillets sont par exemple constitués de papier de sécurité à base de fibres de coton, comportant des filigranes, des planchettes, des fils de sécurité éventuellement fluorescents. Avec la couverture 2 est solidarisée une feuille de papier 6 formant page de garde. Cette feuille 6 est représentée plus en détail sur les figures 2 et 3.In FIG. 1, there is shown a
The
La feuille 6 selon l'invention comporte une zone 7a et une zone 7b minces d'épaisseur e₁. Cette épaisseur e₁ est inférieure à 80 micromètres, de préférence égale à 60 micromètres. La feuille 6 est par exemple un papier obtenu à partir d'une suspension aqueuse de fibres de cellulose sur une machine à papier comportant une forme ronde et une toile filigraneuse embossée. Cette toile filigraneuse est embossée de façon qu'il y ait un dépôt plus important de fibres dans une zone médiane 8 de la feuille 6. La zone médiane 8 a alors une épaisseur e₂ supérieure à l'épaisseur e₁ du reste de la feuille. La zone médiane 8 est donc un filigrane sombre. De préférence, la zone médiane 8 a une épaisseur supérieure à 50 % de l'épaisseur e₁ de la zone mince 7a, 7b. Par exemple, la zone 7a, 7b a une épaisseur de 60 micromètres et la zone 8 a une épaisseur de 90 micromètres (soit 30 micromètres de plus, à savoir 50 % de plus).The
Ainsi, la feuille 6 selon l'invention est suffisamment mince dans les zones 7a et 7b pour que les inscriptions imprimées ou manuscrites 9 portées sur une face 10 d'une zone 7a, 7b, ne puissent être grattées sans que la feuille 6 ne soit endommagée. Si un contrefacteur essaie de falsifier les inscriptions en les grattant, la feuille 6 se perce et/ou se déchire. De même, si un contrefacteur essaie de désolidariser la feuille 6 de la couverture 2 du passeport, cette feuille 6 mince se déchirera. Selon un mode de réalisation, la feuille 6 est rectangulaire. Elle peut cependant comporter des coins arrondis, comme représenté en 11 sur la figure 2, et ce afin d'épouser la forme de la couverture 2 si celle-ci comporte des coins arrondis. Cette feuille 6 comporte une médiane 12 parallèle aux largeurs 13, 14 de la feuille. La zone médiane 8 est un rectangle dont les longueurs 15, 16 sont parallèles aux largeurs 13, 14 de la feuille 6. La zone médiane 8 plus épaisse a pour fonction de permettre de supporter la couture 4 à l'aide du fil 5 et donc la feuille ne percera pas lors de la couture de la couverture 2 et des feuillets 3.Thus, the
De préférence, la feuille 6 est solidarisée par collage à la face interne de la couverture 2.Preferably, the
Du fait que la feuille 6 est peu épaisse dans les zones 7a, 7b, cette feuille est transparente. De façon à opacifier la feuille 6, on la couche à l'aide d'une composition aqueuse comprenant au moins une charge et au moins un liant. La couche est déposée sur la face 10 de la feuille 6 destinée à recevoir les impressions 9.Because the
On préfère déposer une couche qui améliore le rendu d'impression. Par exemple, on peut déposer une couche aqueuse contenant une dispersion aqueuse de polyuréthane et une charge comme du kaolin, ainsi qu'un agent plastifiant tel que la glycérine.We prefer to deposit a layer which improves the print rendering. For example, one can deposit an aqueous layer containing an aqueous dispersion of polyurethane and a filler such as kaolin, as well as a plasticizing agent such as glycerin.
La feuille 6 peut être constituée de fibres de linters de coton et peut avoir un grammage compris entre 20 et 45 g/m² de préférence compris entre 30 et 35 g/m².The
La feuille 6 peut comporter en outre des planchettes et/ou des fils ou fibres de sécurité fluorescents ou de couleur, des agents chimiques d'infalsification, des filigranes clairs ou sombres.The
