Definitions

  • the invention relates to a label for concealing information from a carrier layer, in particular lacquer layer, very particularly from thermosetting lacquer for laser marking, wherein on the lower side of the carrier layer, an adhesive layer is present, as well as the use thereof.
  • the labels serve to provide information, the information being generated by printing or inscription by means of a laser on the label.
  • application fields come into focus, in which information is not transmitted through the label, but where - on the contrary - information to be covered by the label, either right from the beginning of the bond or later, so that the information is first accessible and only after manipulation of the label disappears or is covered.
  • Disposable packaging for drinks will in future also be subject to the deposit system.
  • the customer Upon return of the packaging (mainly plastic bottles) the customer will receive the corresponding deposit. To simplify the return, this can be done in appropriately designed apparatus.
  • DE G 81 30 861 discloses a multilayer label of a thin and a thick self-supporting, opaque pigmented paint layer. Both layers consist of an electron beam-hardened solvent-free applied paint, wherein the layer thicknesses are different.
  • the labeling of the label takes place in that with the aid of a laser, the upper thinner lacquer layer is burned away, so that the lower thicker lacquer layer is visible, the lower layer preferably has a contrasting color to the former.
  • This lettering is a type of engraving, which eliminates the manipulation possibilities as with traditional printing with inks and inks.
  • the label is set by the raw materials used and the manufacturing process so brittle that removal of the same from the adhesive substrates is almost always possible only with destruction.
  • a laser film as from the DE G 81 30 861 is known and obtainable, for example, as tesa 6930® from the company tesa, because of its very brittle product structure good conditions to document possible manipulation attempts and thus to thwart.
  • the laser-printed label can only be removed at a very high cost and under certain conditions in a non-destructive way from its original bonding substrate.
  • a laser-writable multi-layer label material is shown which is composed of a first layer, a second layer differing optically from the first layer, the first layer being removable by laser radiation in accordance with a desired typeface or print image to visualize the surface of the second layer.
  • a transparent plastic film forming a carrier layer is furthermore arranged.
  • the DE 44 21 865 A1 shows a Ein harshlaseretikett from a carrier layer made of plastic, which contains an additive that shows a color change under laser irradiation.
  • the carrier layer is coated on one side with a self-adhesive, which is optionally covered with a release paper or a release film.
  • a security film which has a carrier layer in which an identification medium is contained.
  • the diffusion properties of this identification medium can be specifically selectively and locally changed. If the security film labeled in this way is adhered to a workpiece, the identification medium diffuses toward the substrate surface, where it causes a detectable reaction. In this case, this diffusion or reaction takes place only in those areas of the substrate surface in which the diffusion capability was triggered or not obstructed by the inscription process.
  • the security film allows a clear labeling and identification of the workpiece.
  • the security film is labeled by means of a non-contact method.
  • the labeling of the security film - and thus the change of the diffusion properties of the identification medium - can be done in particular by means of electromagnetic radiation.
  • Particularly advantageous for labeling the security film is the use of a laser, by means of which both a temperature-sensitive and a light-sensitive labeling can take place (the term "light” in this case, the entire laser-accessible range of the electromagnetic spectrum comprises).
  • Lasers have the additional advantage of allowing high-contrast labels with any choice of pattern, allowing rapid changes in the pattern of the label, and being process reliable in the factory environment.
  • a special blade tool can be placed under the label at a shallow angle. By careful cutting movements, it is possible to raise an edge, creating a so-called grip. In this way one creates an attack point, which simplifies a detachment.
  • An additional safety aspect is in the DE 199 04 823 A1 disclosed.
  • a method for producing a film is described in which initially a support carrier film is embossed by means of an embossing tool, wherein the embossing tool has holographic structures. Subsequently, a film is produced on the embossed support carrier film, so that at least one hologram appears on the film.
  • a laser label of at least one layer of plastic is known, which is coated on one side with a self-adhesive, which is optionally covered with a release paper or a release film; Between plastic and self-adhesive, a printing ink is printed.
  • the plastic layer can be transparent.
  • the object of the invention is to provide a way to specifically mask information by means of a label, so that, for example, after labeling the label with a laser, the previously (machine) readable content below the label no longer be evaluated.
  • a detachment of the label should only be possible by destroying it.
  • the invention should meet the aspect of improved security against counterfeiting.
  • the logo may be printed or embossed on the backing layer.
  • the carrier layer preferably has a thickness of 10 to 200 .mu.m, in particular from 50 to 100 .mu.m.
  • Suitable carrier layers consist of plastics such as polyesters, poly (meth) acrylates, polycarbonates and polyolefins, as well as of radiation-curable systems such as unsaturated polyesters, epoxy, polyester and urethane acrylates, as are also used for UV printing inks, in particular those of base polymers according to US Pat DE G 81 30 816 namely, aliphatic urethane acrylate oligomers.
  • the additive may be a pigment, in particular copper hydroxide phosphate or iriodine, a pearlescent pigment based on basic lead carbonate or mica, and be used in addition to the additive titanium dioxide. Furthermore, the additive may be a thermochromic dye.
  • Suitable additives are, in particular, metal salts, in particular copper hydroxide phosphate or else iriodine, a pearlescent pigment, such as is commercially available from Merck. These additives are added to the base polymers (such as in DE G 81 30 861 described) in particular of the order of a few parts per thousand to a maximum of 10 wt .-%, preferably in amounts of 0.1 to 10 wt .-%, in particular from 0.5 to 5 wt .-% based on the total weight of the carrier layer admixed , After production of sheet material by known methods such as extrusion, casting, coating, etc., optionally with subsequent radiation-chemical crosslinking, such films are coated with the adhesive layer.
  • a cover with siliconized release paper then gives the typical structure for starting material from which labels can be made.
  • the carrier layer consists of a lacquer, in particular of a cured lacquer, preferably a radiation-cured lacquer, particularly preferably of an electron beam-cured polyurethane acrylate lacquer.
  • the paint is a brittle paint. The brittleness of the paint is a cause that the label can not be peeled off after bonding because of lack of flexibility of the carrier, but splinters when attempting to detach.
  • the carrier layer consists of a polybutylene terephthalate.
  • paints In principle, four types of paint can be used, provided that their stability is sufficient, for example, acid-curing alkyd melamine resins, addition-curing polyurethanes, free-radical curing styrofoam and the like.
  • radiation-curing paints are particularly advantageous, since they cure very quickly without lengthy evaporation of solvents or the action of heat.
  • paints are for example by A. Vrancken (Farbe und Lack 83,3 (1977) 171 ).
  • the paint layer contains an additional additive of at least 5% by weight, preferably 7% by weight, which is fluorescent or phosphorescent or which is suitable for magnetic or electrical labeling.
  • a falsification by subsequent manipulation is particularly excluded by the fact that the conductivity measurement Vietnamese.Nur from edge to edge of the labels, but can be done between any points. So that a conductivity can be detected here, the complete lacquer layer must be consistently three-dimensionally conductive, which can only be ensured within the framework of the original production process.
  • Such a laser-inscribable label can be produced by adding electrically conductive substances to the formulation of the lacquer layer; This can be done in addition to the previous pigments or at least partially in replacement of the existing pigments in order to maintain the good processing properties of the paint pastes.
  • electrically conductive metallic, organic, polymeric and inorganic substances are suitable as conductive additives, the use of metals being preferred.
  • the own color of the conductive additive has to be considered for the selection.
  • Conductive carbon black is also suitable, but gives a clear black coloration of the carrier layer.
  • a minimum limit concentration of additive should be ensured, so that sufficient particles are present in the lacquer layer to touch and have contact with each other. If this limit concentration is undershot, a conductive path from A to B is no longer ensured in the three-dimensional structure of the base layer. Preference is therefore given to using metallic particles, preference being given to fibers having a high length to cross-sectional ratio, since in this case it is possible to ensure three-dimensional conductivity at lower concentrations than with spherical particles; In addition, the color change of the lacquer layer with the fibers is smaller.
  • the metals used are preferably cost-benefit considerations copper, iron, aluminum and steel and their alloys, but also expensive, highly conductive metals such as silver, gold are suitable.
  • the fiber dimensions are 0.1 to 50 mm in length and cross sections of 1 to 100 .mu.m, wherein preferably metal fibers with a diameter of 2 to 20 microns at a cross-sectional to length ratio of about 1: 100 to 1: 1000 are used.
  • Such fibers are incorporated homogeneously with 0.5 to 25 wt .-%, preferably with 2 to 10 wt .-% in the known recipe and according to DE G 81 30 861 coated and cured.
  • the additives which can be added to the carrier layer may be fine color pigments or else preferably visible particles of the order of 0.1 to 5 mm.
  • finely ground color pigments When using finely ground color pigments, a slight color change of the lettering is produced, with the visible particles a characteristic color mosaic.
  • daylight fluorescent colors the "fingerprint" can be recognized without any aids, which is often undesirable. Preference is therefore given to using color pigments or particles which do not absorb in the region of visible light and are therefore invisible under normal circumstances - it is only when the label is illuminated with a lamp of suitable wavelength that the color pigments are excited and light up in a characteristic way.
  • UV-active systems In addition to color pigments excited by IR radiation, mainly UV-active systems are used. Also suitable in principle are phosphors which are produced by electron beams, X-rays and the like. are excited as well as thermochromic pigments reversibly change in temperature change.
  • the color pigments When selecting the color pigments, care must be taken that they are sufficiently stable for the production process of the labels (film production, adhesive coating) and do not change irreversibly in the process conditions (optionally thermal drying, electron beam or UV curing, etc.). It is advantageous for continuous use of the labels that these usually sensitive phosphors are embedded in a polymer matrix. Further measures against mechanical abrasion and protection against direct oxygen and water contact are not necessary.
  • the same luminescent (phosphorescent) or fluorescent color pigments can be used as are used for the color pigments present in the paint.
  • These color pigments are only or predominantly excited by UV radiation and emit in the visible region of the spectrum (for an overview see, for example Ullmann's Encyclopedia of Industrial Chemistry, 4th edition, 1979, Verlag Chemie ).
  • IR-active luminescent pigments are also known.
  • UV fluorescence systems are xanthenes, coumarins, naphthalimides, etc., some of which are under the generic term “organic phosphors” or “optical brighteners” in the literature. The addition of a few percent of the relevant phosphors is sufficient.
  • formulations with RADGLO® pigments from Radiant Color N.V./Holland or Lumilux® CDPigmente from Riedel-de-Haen can be used.
  • inorganic phosphors are suitable.
  • photoluminescent substances, especially with the emission of light in the yellow range metal sulfides and oxides, usually in combination with suitable activators, have proved favorable. These are available, for example, under the trade name Lumilux® N or as luminescent pigments improved in terms of stability, luminosity and persistence under the trade name LumiNova® from Nemoto / Japan.
  • dyes / pigments listed in the formulation of the lacquer layer or the color in amounts of 0.1 to 50 wt .-%, preferably with 1 to 25 wt .-%, most preferably 7 wt .-%, incorporated.
  • the pre-label material is available for customer-specific use.
  • the label After stamping / laser cutting the desired label geometries and the final inscription by laser beam with lettering, barcodes, logos, etc., the label is in its final form.
  • the label When incorporating, for example, luminescent color pigments into the color layer of the logo, the label has a characteristic afterglow after appropriate stimulation of the luminescent pigments, which allows easy and rapid identification as original label. Apart from the special light source and, if necessary, a screen against disturbing ambient light, no further complex equipment is necessary - after the test the label remains unchanged.
  • Such labels which contain phosphors which emit only in the visible wavelength range in the color of the logo, are also suitable for precisely fitting production (printing, stamping, application, etc.). Instead of separately applied printing or control markings can during processing In particular, after labeling and cutting the labels by laser beam of unpunched roll material, in a downstream control unit at a defined location of the label, the excitation and emission with suitable equipment as a tax stamp for further processing steps or for the production of the next label be used.
  • Customer-specific "fingerprints" of the labels can be realized by printing different logos. Especially regular lines and line patterns create characteristic patterns of luminous dots and are also particularly material and cost saving. After punching or laser cutting of the label and the application on the adhesive substrates a pattern with respect to colors and geometries can be identified by selecting a suitable illumination source at the edge of the label.
