Definitions

  • the present invention relates, as a new industrial product, to a security paper comprising, as a security means, a magnetic product whose specific properties are easily detectable.
  • These first order transformations are, for example, the antiferro-ferromagnetic, ferromagnetic-antiferromagnetic, ferromagnetic-paramagnetic transitions.
  • the papers containing these materials can be printed and then laminated without the means of recognition being able to be called into question.
  • the magnetic material is chosen from the following materials: FeRh. MnAs, Mn 3 SbN, Mn 3 SnC, and (Mn, _xCrX) Z Sb.
  • FeRh. MnAs, Mn 3 SbN, Mn 3 SnC, and (Mn, _xCrX) Z Sb are of the first order transition type, and are particularly advantageous for applications in security paper, since it is known that their very small number and the specific and exceptional nature of their property makes it impossible to use them. substitution of a conventional material.
  • the varnish is deposited on a polyester film (20 microns thick) by a heliographic printing process, the quantity of varnish deposited is of the order of 5 to 10 grams per m2.
