Definitions

  • the invention relates to the field of stationery. It relates to a new tamper-proof security paper comprising an aromatic product, a process for rendering a paper to be tamper-proof and an aqueous or organic composition useful, in particular, for rendering a tamper-proof paper.
  • French Patent No. 2,365,656 describes a security paper comprising a chemical sensitizing composition based on an indicator of acid-basicity, very sensitive to variations in pH.
  • the indicator is chosen, in particular, from the group of phthalein or sulfophthalein.
  • the pH rises due to the action of the eraser
  • the paper develops a color.
  • all of the products described are of delicate papermaking use, mainly because of their solubilization conditions, pH of use or reversibility or stability.
  • French Patent No. 2,399,505 and its certificate of addition 2,402,739 describe a security paper comprising a chemical sensitizing composition based on a salt of oxypyrene tricarboxylic acid, called Pyranine.
  • Pyranine a salt of oxypyrene tricarboxylic acid
  • French patents no. 2 406 027, 2 427 426 and its certificate of addition 2 432 576 describe a security paper comprising dinitrophenols which, under the action of an erasing pencil, are colored in non-fluorescent yellow.
  • French Patent No. 2,410,702 describes a security paper comprising a chemical sensitizing composition composed of Pyranin combined with an optical brightener and various other compounds. The action of an erasing felt on such a paper leads to a fluorescent yellow coloring.
  • the object of the invention is to provide a compound which, associated with a paper, makes it unforgeable, even with erasers, by instantly developing a color clearly detectable with the naked eye.
  • the paper according to the invention is characterized in that it comprises, on its surface and / or in its mass, at least one compound corresponding to the formula:
  • the paper can have any fibrous constitution, purely cellulosic or partly synthetic, to which can be added the conventional stationery additives, namely mineral fillers, various resistance agents, binders, resins, shading dyes, neutral bonding products, acid or basic, alumina sulfate for acid bonding or pH adjustment.
  • the conventional stationery additives namely mineral fillers, various resistance agents, binders, resins, shading dyes, neutral bonding products, acid or basic, alumina sulfate for acid bonding or pH adjustment.
  • N0 2 can be in ortho, meta or para of CH 2 CN.
  • the paper will comprise at least 0.0001 g / m 2 of the compound and, advantageously, between 0.01 and 0.15 g / m2.
  • the paper can also include sensitizing reagents, similar to those already used currently in security papers, for example products ensuring a modification of the appearance of the paper by contact of the latter with acids, oxidizing reagents.
  • sensitizing reagents similar to those already used currently in security papers, for example products ensuring a modification of the appearance of the paper by contact of the latter with acids, oxidizing reagents.
  • these products are introduced, either in aqueous solution, in which case it is necessary to ensure their retention on the fibers by direct bonding or by means of fixing agents, or in the microdispersed or pigmented precipitated state. .
  • ferric chloride / manganese ferrocyanide couple provides a reaction to attempts at falsification by acids, oxidants and erasers with an acid reaction (of the "corector" type).
  • These papers may also contain, in their mass, in the pigmented state, dispersed, one or more dyes insoluble in water but organo-soluble, so as to preserve the writings or statements made on these papers vis-à-vis attempts at falsification using organic solvents.
  • these papers can be watermarked or contain various devices intended to ensure recognition, such as fibers, pellets, colored and / or fluorescent particles.
  • a first method for making a falsifiable paper consists of incorporating the compound of formula (1) during the manufacture of the paper.
  • a second method consists in depositing on one or both sides of a sheet of paper an aqueous composition comprising a compound of formula (1), as defined above, and a coating binder.
  • coating binders mention may be made, by way of indication, of synthetic or natural polymers with compatible hydroxy terminations, such as starch, polyvinyl alcohol and cellulose derivatives.
  • the category of surfactant selected will depend on the structure of the compound corresponding to formula (I) used. Thus, for the substructure compounds (1), a surfactant from category (B) will advantageously be chosen and, for the substructure compounds (2), a surfactant from group (C) and, among these, the quaternary ammonium compounds.
  • chlorine activators such as bleach can be added to this composition.
  • a third method consists in depositing on one or both sides of a sheet of paper a composition comprising a compound of formula (1), an organic solvent and a compatible coating binder.
  • solvent there may be mentioned esters, ketones, alcohols, essences or aromatics.
  • composition designates solutions, that is to say the compositions in which the constituents are in the form of solutes but, also, the dispersions partially or not dissolved.
  • compositions can be deposited using a coating technique used in stationery (for example size press, roller systems, blade.
  • a subject of the invention is also the compositions as such.
  • the coloring obtained with ink erasers and bases is purple-magenta.
  • the paper thus treated also reacts with bleach, giving a beige-brown color, with acids and acid-erasing products (of the "corector” type), producing blue, the solvents color differently the paper according to their nature.
  • reaction with acids, bleach and acid reaction erasers can be obtained by addition of products usually known in the coating solution or in the bulk.
  • the paper thus treated becomes purple-magenta in the presence of bases, reducers or erasable felts, and. as before, in blue with the acids and the acid-erasing products with acid reaction (of the "corector” type), in brown with the bleach and of a variable coloring according to the solvents (according to the dye used).
  • a paper support During the manufacture of a paper support, are introduced into the mass, in addition to the reagents previously described as a ferric salt, a precipitate of manganese ferrocyanide and one or more dispersed organosoluble dyes, paranitrophenyl acetonitrile: finely divided, in combination with hexadecyl pyridinium chloride. After formation of the sheet, a reactivity identical to that described in Example 1 is obtained (magenta coloring with erasers, bases and reducers, blue with acids and erasers with acid reaction (of the "corector” type). ), brown with bleach, variable with solvents).
  • the paper is white and not fluorescent after facing.
