Definitions

  • the invention relates to a sheet or film which can be used for manufacturing security documents, which is printable and which has a high print rendering, as well as good resistance to circulation, especially after printing.
  • the invention relates more particularly to sheets of paper for banknotes or other valuable securities which can in particular be printed by offset printing and / or by intaglio printing. It further relates to a composition for surface treatment or impregnation of a sheet so as to simultaneously give it properties of good printability and resistance to circulation.
  • security documents for example papers for banknotes or for checks or any other security of value include chemical or physical means of authentication and / or indicators of falsification.
  • falsification indicator means react, for example, to acids (hydrochloric, citric, acetic, sulfuric, etc.), to bases (especially soda), to oxidants (bleach), to reducers and to solvents.
  • a given security document does not generally contain all of these means, since the cost of manufacturing the document increases with the number of authentication means and with their sophistication.
  • the security documents always include a superficial impression and this is why it is necessary to carry out a printing of superior quality, both with regard to the colors and the layout, so as to make it difficult for them to be imitated by counterfeiters.
  • the general public is not not very attentive to the quality of the drawings and / or prints brought to the surface of a security document, but knowledgeable people like bank staff or merchants are very sensitive to the details of a drawing, the finesse and in general when printed, and can therefore judge the authenticity of a document, with the naked eye or with a magnifying glass.
  • the print rendering is the fact that the line obtained by printing is perfectly clear, that is to say that it does not have any burrs or in term used by the skilled person in the "feathering". These burrs cause the lines to spread out more than is desired, or the difficulty of producing an impression comprising very close lines without the risk of blurring. Therefore, the central bank that prints the paper to obtain security documents is forced to make insufficiently fine prints. It is therefore difficult to produce micro-prints. However, micro-prints are very useful as security elements because they are difficult to reproduce by photocopiers who currently cannot reproduce very fine prints. Print rendering is also characterized by the color density of the print.
  • the human eye has sufficient resolution to distinguish between an impression having a good rendering and an impression comprising a "feathering".
  • the printing rendering on the security documents is quite poor and it is therefore possible to easily forge them using color photocopiers which are capable of reproducing almost exactly the color tones of an authentic document. Counterfeiting will not be obvious to the eye, even to a knowledgeable person, since the print rendering of the authentic document is not sufficiently superior to that of the image reproduced by photocopying.
  • the quality and beauty of the print also contributes to the brand image of the document sender.
  • the quality of the printing contributes to the prestige of the country which puts them into circulation. This is another reason to be careful when printing these documents.
  • pigments and binders that can be used to make such a layer is very wide. Pigments are most often mineral fillers, sometimes plastic pigments.
  • the binders can be chosen from starch, casein, animal glue, polyvinyl alcohol, natural or synthetic latex, etc.
  • pigmented layers containing bentonites have been studied in the field of usual printing-writing papers (TAPPI, vol.59, n ° 12, December 1976, NEW YORK, pages 76-80; R.L. JANES et Al).
  • the sheet of paper is impregnated, before printing, in a bath which essentially contains one or more binders chosen for their very high mechanical characteristics.
  • US-A-3,281,267 describes a coated paper used for printing and / or writing. These papers are used for magazine covers, for advertising. They must be very shiny and very icy. In addition, they must be flexible. To glaze these papers, a calendering is carried out which requires that the paper be flexible. In addition, we want the paper to be opaque. In this document, it is mentioned that flexibility is given by the elastomeric nature of the layer compound, while the so-called “plastomeric” properties make the coating composition moldable. The elastomer is added to the thermoplastic resin to give it the desired flexibility. It is even possible not to add an elastomer if the "plastomer" is sufficiently flexible. After deposition of the layer and calendering, the sheet is subjected to a heated surface which polishes the surface to obtain the gloss.
  • a coating composition described comprises an elastomer content of between 15 and 20 parts per 100 parts of pigments.
  • Document FR-A-2 288 186 describes a process for manufacturing a paper coated with a composition containing a particular amorphous filler in order to improve the printability of the paper by gravure printing.
  • a typical composition contains a maximum of 7 parts of latex binder for 100 parts of fillers.
  • the maximum rate of latex binder used is 15 parts per 100 parts of fillers, which is a conventional rate of binder for printing / writing papers.
  • the nature and characteristics of the latexes used are not specified. We do not study or envisage the use of a particular binder which is elastomeric and at particular rates greater than 25 parts per 100 parts of fillers.
  • the present invention therefore aims to improve the rendering printing of a sheet intended for the production of security documents, without degrading the resistance to circulation of the printed documents.
  • the invention also aims to improve the resistance to circulation of such documents.
  • the Applicant has overcome the prejudices of those skilled in the art, namely that it has subjected the sheet to a surface treatment, by means of a particular composition, this treatment possibly being, for example, a coating.
  • the Applicant after having tried numerous compositions containing at least one binder and at least one filler, has managed, surprisingly, to solve the problems posed by using a composition containing at least one filler and at least one binder of elastomeric character.
  • composition containing a binder and a filler does not increase the receptivity of the sheet to soiling since it improves the receptivity of the sheet to inks.
  • the invention provides a printable sheet, usable for manufacturing security documents, having a high print rendering and resistance to circulation, which is characterized by the fact that at least one of its faces is treated by a composition comprising one or more fillers chosen from mineral fillers and / or plastic coating pigments and at least one elastomeric binder, the binder being in an amount greater than 25 parts per 100 parts of fillers by dry weight.
  • the elastomeric binder can however be used in admixture with other binders usually used in stationery. Tests carried out by the Applicant have shown that binders such as starch or PVA, even insolubilized, do not allow the impression required for security documents to be maintained when these binders are used alone with a filler.
  • the elastomeric binder can be chosen from the group formed by aqueous dispersions of polyurethane, of acrylate copolymers, of optionally carboxylated styrene-butadiene copolymer, of polymers one of the monomers of which is acrylonitrile or isoprene or neoprene. , or their mixtures.
  • Polyurethane is preferably used.
  • composition can comprise other dispersing additives, viscosity modifying agents, plasticizers, bacteriostatic agents, fungicides for example. It is not excluded that it includes other authentication or tampering agents.
  • the filler is preferably mineral, in particular it is chosen from silicas or kaolins. It can however be optionally chosen from other coating pigments such as plastic pigments.
  • the charge can have any BET specific surface. It may as well have a specific surface area measured according to the BET method (standard DIN 66 131) which is low, of the order of 5 to 20 m2 / g, as a specific surface area which is high, for example of the order from 200 to 300 m2 / g (the BET method gives a measurement of the total specific surface).
  • coats of the "reverse-roll”, “champion”, “bill-blade”, dragging blade or air knife type can be used. It is preferable to choose an air knife coater. Indeed, this type of coating respects the filigree, that is to say its relief.
  • the sheet to be treated according to the invention can be a sheet based on a cellulosic composition, partially or completely synthetic or a film of synthetic material.
  • the sheet is bank note paper.
  • the invention also aims to provide a composition for the treatment of at least one face of a sheet, giving this sheet a high print rendering and resistance to circulation, which is characterized by the fact that it comprises at least one filler and at least one binder of an elastomeric nature, the binder being in an amount greater than 25 parts per 100 parts of filler by dry weight.
  • the weight of the deposited layer is between 1 and 15 g / m2 in dry, preferably of the order of 10 g / m2 in dry.
  • results are estimated visually (with the naked eye or with a magnifying device (magnifying glass, microscope) and by comparison.
  • a control sheet which has not been treated is compared with a sheet treated with the pigmented compositions according to the invention. It is observed that the print rendering is much better for the sheets produced according to the invention and that the resistance of the sheet to circulation, in particular after printing, is not less than that of the control. In some cases it has even been improved.
