Definitions

  • the present invention relates to the field of securing documents or products by affixing a optically active component for the verification of authenticity.
  • optical effects produced by the means prior art authentication generally consist in animations, which it is not always easy to verify compliance.
  • these events are produce under lighting and observation conditions very specific, and the unsophisticated user may encounter doubts in the verification of whether the animation observed - sometimes with difficulty due to a bad positioning of the controlled object or bad lighting conditions - matches well with the one prescribed for an authentic object.
  • the object of the present invention is to remedy this drawback by proposing an optical component allowing easy and unambiguous verification, while guaranteeing a great difficulty of counterfeiting.
  • the invention relates in its most general acceptance a component for authentication of a document or product, presenting a transparent plastic film supporting an embossed stamping varnish to present at least a diffracting grating, the embossed surface being at least partially coated with a metallization layer, characterized in that the embossed stamping varnish has a first metallic area producing a rainbow effect according to a first orientation of the component with respect to a direction lighting, said rainbow effect disappearing when the component is oriented perpendicular to the first orientation, and a second demetallized zone then coated a layer of a dielectric material, preferably with a high optical index, producing a colored effect of a first color for a first orientation of the component and a second color different for orientation perpendicular to the first orientation.
  • Each of the two areas represents information recognizable.
  • the first orientation corresponds to an orientation in which the observer and the source are in a plane perpendicular to the surface of the component.
  • the second area is an area with a deposit of a high index dielectric material.
  • the invention also relates to a method of preparation of a component for the authentication of a document or product characterized in that it includes a step of stamping a varnish supported by a transparent film, a step of metallization of the stamped varnish, a demetallization step partial of the stamped varnish thus prepared and a deposition step of a dielectric material.
  • the method includes a step additional coating.
  • the step of demetallization is carried out by masking the parts of the first zone with a varnish, then by passing the component thus prepared in a chemical bath.
  • Other methods of demetallization known in the prior art are applicable.
  • Figures 1 and 2 show views along a first orientation of the component (observation at noon) and according to a second orientation of the component (observation at 90 °). It presents a first peripheral zone 1 presenting a metallic look, with an easy rainbow effect verifiable.
  • the central zone 2 has a uniform color, for example blue.
  • FIG. 3 represents a view according to a plan of section A-A.
  • the component is formed by a polyester film 11 supporting a stamping varnish 3 embossed by stamping, in a manner known for production holograms or diffringent structures intended for document authentication.
  • the stamped surface is coated by vacuum deposition of a metallization layer.
  • the metallization material is for example aluminum.
  • This metallization layer is partially deleted to leave only the peripheral area 1, resulting in metallized parts 4 and 5.
  • the part corresponding to the coloring zone 2 variable is demetallized by a process of masking the metallized surface, except for the area to be demetallized, with a protective varnish.
  • the component is then immersed in a bath destroying the metallization layer, in places not protected by varnish.
  • the assembly thus prepared is then coated with a adhesive film 7 deposited for example by coating.
  • the component thus produced can be affixed to a document or product to protect, for example by gluing.
  • It can also be sealed between an object or a document, and a sealing film protecting the object or document, and allowing to detect any attempted withdrawal of this movie.
  • FIG. 4 represents an alternative embodiment, for the production of a hot stamping film or a film rolling.
  • Stamping varnish 3 is coated on a layer detachment 10 itself supported by a transparent film 11, for example a polyester film.
  • FIGS 5 and 6 show variants of production of an optical component according to the invention.
  • zones 20, 30 shown in black can be formed either by the metallized area or by the demetallized area covered with dielectric.
  • the component can also have a line of micro lettering 25.
