Definitions

  • the present invention relates to a method for obtaining security paper, the said method being aimed at successfully enhancing the extent of security of this kind of paper from potential counterfeits, the same being specifically applicable to the field of paper money and to obtaining any other kind of document requiring a paper with like benefits.
  • the invention also relates to the security paper the said method yields.
  • the method for obtaining security paper subject of the invention, and more specifically the paper the said method yields stands as a new alternative in this field, allowing the new means to be used to "personalize” the paper, be it on their own or preferably together with the aforesaid means.
  • the method subject hereof relies on the use of raw materials, naturally besides paper that is obtained by any suitable conventional means, namely a water resistant ink and a water soluble medium.
  • the water resistant ink is used for printing any manner of indicia, such as letters, anagrams and so forth, upon the said water soluble medium.
  • the said indicia After obtaining the said indicia, suitably printed upon the said medium, the latter is left in water or an aqueous liquid for as long as it requires to be dissolved, whereupon the indicia remain in suspension and ready to be incorporated to the security paper, at a third and final operative stage, and in a manner similar to how the security planchettes or the fibrilles are conventionally incorporated to the said paper.
  • the ink used to obtain the indicia to contain fluorescent or phosphorescent pigments, and also magnetic materials, depending upon the system to be subsequently employed in detecting such indicia and verifying the document.
  • the printing ink used in the method subject hereof must be insoluble in water, for instance based upon an acrylic polymer, or styrene, butadiene, or epoxy polymer or also acrylonitrile, or such others as provide insolubility in water, which ink can as aforesaid be provided with fluorescent or phosphorescent pigments, preferably brightly coloured.
  • Such indicia can be letters or anagrams of any kind, but shall preferably be conceptually related to the issuer of the document.
  • the said indicia can in one way or another refer to the country of origin or issue of the said currency and similarly to the institution issuing a document, if the latter is in turn the case.
  • the medium envisaged to print the ink is provided as polyvinyl alcohol or mixtures of other soluble polymers.
  • the said indicia remain floating upon the ready-formed paper mass and, given the special optical characteristics thereof, they can be recognised on the dry paper with the assistance of an ultraviolet light by reflection, or under normal light by transparency, the same hence lying "latent" within the paper until inspected using the aforesaid optical means.
  • the indicia can carry magnetic or simply metal materials, and can hence be recognised within a magnetic field.
  • the said indicia are made of a flexible material, given the composition of the ink, on being inserted in the sheet of paper making up the document in question, the same are subjected to no tension whatsoever and do not disrupt the printing methods, and are compatible with any other known security.

Abstract

Le procédé consiste à incorporer au papier de sécurité proprement dit une série de signes, qui peuvent être des lettres, des anagrammes, etc., obtenus avec une encre résistante à l'eau avec laquelle on effectue l'impression correspondante sur un support soluble à l'eau, de sorte qu'après cette impression on procède à l'élimination du support, après quoi les signes restent en suspension et peuvent être appliqués au papier de manière semblable à l'incorporation à un tel papier de planchettes ou fibrilles de sécurité classiques. La bande mentionnée comporte en outre des pigments fluorescents ou phosphorescents pour l'identification de signes à l'aide de lumière ultraviolette ou par transparence, et éventuellement des matériaux magnétiques ou simplement métalliques pour la détection des signes à l'aide d'un champ magnétique.
