  • the formation of color images is carried out, in particular, by laser engraving in combination with special protective effects recorded by hardware.
  • Such technologies are implemented using inexpensive equipment and available components. However, this also leads to a relatively easy forgery and imitation of documents. In addition, special expensive equipment must be used to authenticate.
  • the problem solved by the invention is the creation of a personalization technology for a valuable document, in which the effect of changing a personal attribute is clearly visible to the naked eye by the characteristic features of images formed by exposure to a valuable document with external radiation.
  • At least one of the recording layers is made of a polymer composite material with a transition temperature in the viscous-fluid state from 20 to 100 ° C and having a reactivity to temperature and optical, radiation, electron-ion radiation, leading to irreversible polymerization, and this layer contains a filler in the form of magnetic particles that form personalization images distinguishable in transmitted or reflected light.
  • magnetic particles have the form of plates - flakes, needles, or close to a spherical shape.
  • Magnetic particles can be made of transparent or translucent materials, and can also have a color or interference coating.
  • the problem is also solved by the fact that the proposed method of personalization of the valuable document described above.
  • the method includes forming a personalization image by exposing the recording layer to an external magnetic field and radiation, according to the invention, recording a personalization image is carried out by exposing the recording layer to a magnetic field of a certain direction and magnitude and radiation, leading to a decrease in viscosity and / or irreversible polymerization of the material of the recording layer in irradiated areas.
  • an additional polymerisation operation is possible after recording a personalization image.
  • a personalization image is recorded using external laser radiation. Recording personalization images is possible using wide beams of radiation and controlled and / or uncontrolled banners.
  • a personalization image occurs when the areas of the recording layer are combined with a magnetic field and external radiation (irradiation with IR, light, UV, X-ray, radiation, electron or ion beams), leading to polymerization crosslinking of the polymer-oligomer-monomer base material recording layer.
  • point-by-point or analog (continuous) recording of personalization images by focused or defocused radiation through transmitting controlled or uncontrolled banners in a recording polymer composite layer containing a filler in the form of magnetic particles is carried out.
  • reorientation and redistribution of magnetic particles occurs and their subsequent fixation due to the simultaneous and / or subsequent crosslinking of the polymer-oligomeric-monomer base of the recording layer in the places subjected to irradiation.
  • polymerization of the recording layer by external radiation is additionally carried out.
  • the distribution and orientation of magnetic particles is determined by the viscosity of the material of the layer, the method of its deposition, the magnetic characteristics and shape of the magnetic particles, and the magnitude and direction of the acting magnetic fields.
  • the position of the magnetic particles is fixed, in particular, images can be formed using radiation from laser and LED emitters or lamps with a wide spectral range from 200 nm to 10,000 nm).
  • Images can be black and white, grayscale and color.
  • the value of the order of 10 - 10 AUM conduct point-by-point recording with a point size equal to the diameter of the focused laser beam.
  • the recording is carried out by heating the magnetic particles with laser radiation, while the particles heat the thermoplastic polymer material around them. Magnetic particles rotate in a heated viscous flowing polymer in the direction of the applied magnetic field and / or line up into thin filament-like formations along the lines of the magnetic field. After the action of the laser pulse, the thermoplastic polymer cools and fixes the position of the rotated and aligned magnetic particles.

  • a recording layer 3 is placed with a sufficiently low (20 ° C-100 ° C) softening temperature — a transition to a viscous-fluid state. It may also be in a viscous liquid state prior to image recording procedures.
  • a layer of transparent sevilen doped with activators which made it possible to fix the temperature of its transition to a viscous-fluid state in the range (20 ° ⁇ -100 ° ⁇ ).
  • the specified layer is located on the polymer substrate 4 and contains a powdery filler in the form of magnetic particles uniformly distributed throughout the volume of the recording layer.
  • Recording identification information was carried out as follows. An identification document was placed in a magnetic field 5 from a source of a uniform magnetic field 6 and the standard laser engraving procedure was carried out from the side of the transparent coating layer 2 in the same way as when recording identification information on plastic documents with photosensitive (laser active) polycarbonate films.
  • regions 8 of the recording layer with magnetic particles 9 are illuminated pulsed, dotted areas due to heating, the viscosity of the recording layer decreases, and the magnetic particles under the action of the applied external magnetic field 5 are oriented and spatially redistributed.
  • more rigid fixation of images can be carried out by irradiating them during recording or after its implementation by radiation, which leads to crosslinking of the polymer material of the recording layer.
  • the sevilen-based layer was irradiated in an electron-irradiation unit L-210 with electron beams with a power of 2-10 MEV. Due to the polymerization of the material a recording layer in contact with magnetic particles, it is impossible to re-record in places with already recorded. The latter circumstance is important to prevent the possibility of unauthorized rewriting of personalization and identification information. Personalization images obtained using reoriented magnetic particles can easily be distinguished in transmitted or reflected light upon visual observation of the document.
  • the recording layer is located on the base 4, which can be transparent, translucent and opaque.
  • the recording layer is affected the magnetic field 5 created by the source 6.
  • the magnetic field is perpendicular to the plane of the recording layer. Particles were previously oriented parallel to the plane of the recording layer.
  • the configuration of the location of open transparency cells determines the configuration of the generated images.
  • the recording time of one image depending on the composition of the basis of the recording layer was several seconds. Since magnetic particles are fixed only in the irradiated areas, when opening new transparency cells and changing the direction of the magnetic field 5 during subsequent recording cycles, other images may form in the recording layer.
  • the contrast of the observed images in reflected or transmitted light is determined the location of magnetic particles in the irradiated local areas.
  • Image recording can also be carried out through uncontrolled banners.
  • the banners are made in the form of transparent plates with coatings that are opaque to the radiation used in the recording. Images in banners are formed by local removal of opaque coatings.
  • the recording of various images in one recording layer is carried out by placing the recording layer under the plates with different images and changing the direction of the magnetic fields when recording each image.
  • the invention is applicable in the field of security printing, and more specifically, in the manufacture and personalization of plastic documents, such as a passport, driver’s license, identity card.
