Definitions

  • the invention relates to a security tag with tamper evidence, which is constructed on a paper support.
  • these security labels are constructed on a carrier substrate of a flexible plastic film and then have a quite reliable triggering behavior.
  • these security labels can also be constructed on a carrier substrate consisting of a paper or a composite of paper with a plastic film, although here the practice shows that in such labels the triggering of the tamper evidence does not work reliably.
  • the composite can usually be more or less easily separated, so that such a security label is only partially secure against manipulation.
  • the object of the invention was therefore to provide a security tag with tamper evidence, which is constructed on a paper substrate is, has the typical paper behavior and also allows reliable triggering of tamper evidence.
  • the invention therefore relates to a tamper evident security label comprising a carrier substrate, a release lacquer layer and a functional layer, characterized in that the carrier substrate is a paper substrate provided with a primer lacquer layer closing the surface of the paper substrate.
  • the invention is based on the finding that the separating lacquer layer applied according to the known prior art to the surface of the paper or else a functional layer, such as a colored lacquer layer or a metallic layer, penetrates into the paper and thus impedes the unambiguous triggering of the tampering detection.
  • the paper substrate consists of pulp-free or cellulose-containing paper, this paper substrate having a weight per unit area of 20-500 g / m 2 , preferably 40-200 g / m 2 .
  • the paper may also contain a proportion of plastic fibers.
  • the surface of the paper substrate is now closed according to the invention by means of a priming lacquer layer, wherein this primer lacquer layer does not penetrate into the paper, but only closes the surface and thus prevents the penetration of the release lacquer layer or a functional layer in the paper.
  • the release lacquer layer and / or the functional layer thus remains on the surface of the underlying lacquer layer and thus a trouble-free triggering of the tamper evidence is achieved.
  • the priming lacquer layer can be used as a printed layer by means of a printing process, such as gravure printing, flexographic printing, screen printing and the like can be applied to the paper surface by roll coating methods such as a plain roll method or by brushing or spraying.
  • a printing process such as gravure printing, flexographic printing, screen printing and the like
  • roll coating methods such as a plain roll method or by brushing or spraying.

  • This method is particularly suitable for papers having a Bendtsen roughness according to ISO 8791-2 of ⁇ 50 ml / min and a Bendtsen porosity according to ISO 5636-3 of ⁇ 70 ml / min.
  • this primer lacquer layer is brittle, thereby having similar tear properties as the paper substrate.
  • Particularly suitable are radiation-curable, in particular UV-curable, coatings, in particular based on acrylic methacrylates, for example trimethylolpropylene triacrylate, hydroxyethyl methacrylate, amine-modified polyfunctional polyethyl ether copolymers, acrylic epoxy resins, polyfunctional aliphatic urethane acrylates or mixtures thereof, to which one or more photoinitiators are added for crosslinking.
  • Suitable photoinitiators are preferably bis (2,4,6-trimethylbenzoyl) -phenylphosphine oxide or mixtures of bis (2,6-dimethoxybenzoyl) -2,4,4-trimethyl-pentylphosphine oxide with 1-hydroxycyclohexyl-phenyl ketone.
  • such a lacquer layer is provided on a substrate made of a flexible plastic film, for example a polyester film, and then transferred to the paper substrate using an adhesive layer, for example a laminating adhesive layer or a hot-melt adhesive layer, under the action of pressure and / or temperature on the paper or sealed. Subsequently, the plastic film is peeled off.
  • a flexible plastic film for example a polyester film
  • an adhesive layer for example a laminating adhesive layer or a hot-melt adhesive layer
  • the paper substrate treated in this way is then provided on the surface carrying the priming lacquer layer with a structure which permits tampering.
  • a partial release lacquer layer is applied in a first step.
  • a release lacquer layer in particular known, poorly adhering lacquer compositions, for example based on cycloolefin copolymers, nitrocellulose, acrylates, polyvinyl chloride, ethylene acrylate copolymers or styrene acrylates in a suitable solvent in question.
  • chlorinated polyolefins are added to adjust the adhesion.
  • the proportion of the chlorinated polyolefins in the composition may be 1 to 50% by weight, preferably 1 to 25% by weight, more preferably 1 to 15% by weight, relative to the base polymer.
  • even very thinly applied polyamide, polyethylene, fluoropolymer wax layers or silicone coatings can be used as the release layer.
  • the release lacquer layer may be applied in the form of a pattern, in the form of symbols, letters, numbers, images, patterns, logos, lines, guilloches, texts, writings or the like.
  • the adhesion of the partial release lacquer layer can be adjusted as required such that the adhesion of the release lacquer layer to the priming lacquer layer is greater than the adhesion to the layer subsequently applied to this release lacquer layer.
  • the adhesion of the release lacquer layer may be adjusted such that the adhesion of the release lacquer layer to the layer subsequently applied to the release lacquer layer is higher than the adhesion to the underlying lacquer layer.
  • a functional layer is then applied to this partial release lacquer layer.
  • a functional layer is understood as meaning a layer which may have security features, for example optical security features such as a defined color, or optically variable properties or reflective properties. This layer may be, for example, a print layer or a metallic layer.
  • a printing layer has an optical security feature and is preferably colored, white or black.
  • the optical properties of this layer can be visualized by visible dyes or pigments, luminescent dyes or pigments which fluoresce or phosphoresce in the visible, in the UV range or in the IR range, effect pigments, such as liquid crystals, pearlescent, metal pigments, bronzes and / or make multi-layer color change pigments and heat-sensitive inks or pigments accordingly.
  • such a printing layer is embodied in a color contrasting with the color of the paper substrate.
  • a metallic layer may be deposited by applying metals or metal compounds or alloys by PVD or CVD techniques.
