Definitions

  • the invention relates to a laser-inscribable label material, at least consisting of a carrier layer made of plastic film and a coating carried by it, the coating being able to be removed from the carrier layer by means of laser radiation in accordance with a desired writing or printing image, exposing the surface of the carrier layer.
  • Laser-inscribable label material of the type mentioned is known and is used in particular for the production of high-quality labels or nameplates and similar purposes.
  • the plastic film forming the backing layer is colored through and the coating applied thereon is known from e.g. a different colored lacquer layer.
  • a disadvantage of this known laser-inscribable label material is that it is very expensive, which is caused in particular by the use of solid-colored plastic films as the carrier layer.
  • Another disadvantage is seen in the fact that the label materials available on the market have only a small variety with regard to their color combinations, so that special requests with regard to the color design do not or can only be fulfilled with a high additional cost for the production of a solid-colored plastic film in a desired color.
  • a laser-inscribable label material of the type mentioned above which is characterized in that the plastic film forming the backing layer is transparent and that the backing layer on its side facing away from the first coating, which can be removed by laser radiation, has a second, from the first Coating optically different coating carries.
  • the carrier layer By using a transparent plastic film as the carrier layer, a simple, common material can be used for this, which is inexpensive to manufacture and obtain.
  • the additionally provided second coating then makes it possible to optically differentiate the typeface or print image to be represented by the label, the second coating becoming visible wherever the first coating is removed by means of laser radiation.
  • Both the first and the second coating can be applied to the carrier layer in different ways and formed from different materials. Preferred configurations for this are given in claims 2 to 5.
  • the vapor-deposited metal layer can consist of aluminum, for example either the surface can be glossy or matt.
  • a color coating applied by printing can be formed from practically any color material, for example lacquer or printing ink based on acrylic, latex or synthetic resin, which is preferably applied by means of screen printing or flexographic printing.
  • first and / or second coating applied by printing technology can advantageously be implemented in multi-color printing, which allows the production of labels which have more than two colors.
  • a further embodiment of the label material according to the invention suggests that the second coating is translucent. This allows the label material to be illuminated, for example for use on display surfaces illuminated from the inside. The area of the label in which the first coating has been removed then appears illuminated, so that a high-contrast, optically very perceptible representation is achieved.
  • this is a polyester or PVC or polyolefin film.
  • these materials offer the necessary stability and the temperature resistance required for laser marking and, on the other hand, they can be easily provided with coatings and can be produced inexpensively.
  • the second coating has an adhesive layer on its side facing away from the carrier layer.
  • the adhesive layer In order not to hinder the back of the label material from being illuminated by the adhesive layer, it is proposed that it consist of a transparent or translucent adhesive.
  • the adhesive layer is a transfer adhesive with a removable protective cover.
  • a transfer adhesive is advantageously easy to handle and easy to transfer to the back of the second coating in the manufacture of the label material.
  • the removable protective cover for example a paper layer, then remains on the adhesive layer until the label is attached.
  • the exemplary embodiment of the label material 1 shown here consists of a total of five layers which are arranged one above the other.
  • the label material can be produced, for example, in the form of sheets or as an endless material.
  • the layer thickness ratios are shown here purely schematically; in practice, the label material including the protective cover has a total thickness of, for example, 100-200 ⁇ m.
  • the supporting part of the label material 1 is formed by a carrier layer 20 made of a transparent plastic film, such as polyester or PVC or polyolefin film.
  • a first coating 21 is applied to one side, the upper side in FIG. 1, here a vapor-deposited metal layer, e.g. made of aluminium.
  • a second coating 22 is applied to the second side of the carrier layer 20, here the lower side.
  • This coating 22 is a color coating, e.g. from a printing or lacquer ink applied in screen printing or flexo printing.
  • the adhesive layer 30 is provided with a protective cover 31, e.g. a paper layer that is peelable from the adhesive layer without the adhesive detaching from the second coating 22.
  • the first coating 21 is a vapor-deposited metal layer, this layer is opaque.
  • the carrier layer 20, on the other hand, is transparent, that is to say transparent.
  • the underlying second coating 22 is applied here in such a thickness and color pigment concentration that it is translucent.
  • the adhesive layer 30 is also transparent or at least translucent.
  • FIG. 2 of the drawing shows schematically how the label material is laser-inscribed.
  • a laser 50 and the label material 1 are moved relative to one another, a laser beam 51, which is generated by the laser 50 and is emitted onto the label material 1, stored electronically as required Data that corresponds to the desired typeface or print image is switched on and off.
  • the surface of the label material 1 is gradually worked off in the form of a regular grid, for example from rows and columns running at right angles to one another, as a result of which a large number of identical or different lettering or printed images is produced.
  • the first coating 21 is evaporated in the irradiated areas 21 ′ by the thermal energy applied to the label material by the laser beam 51, so that the surface of the transparent carrier layer 20 is exposed there. From the visible side of the label material 1, i.e. in FIG. 2 from above, the second coating 22 lying under the carrier layer 20 is now visible below the regions 21 'in which the first coating 21 has been removed.
  • a punching line 40 can be seen in FIG. 2, which extends through the first coating 21, the carrier layer 20 and the second coating 22.
  • the label material 1 can later be cut along such a punching line 40 in order to break it up into individual labels.
  • the punched line 40 does not penetrate the adhesive layer 30 and its protective cover 31, so that the label material 1 thereby remains sufficiently cohesive until it is used.
  • FIG. 3 of the drawing finally shows a finished label 10 that is adhesively attached to a wringing surface 60. From top to bottom, the first coating 21, the carrier layer 20 and the second coating 22 can be seen here again. Below the second coating 22 is the adhesive layer 30, which is an adhesive bond between the label 10 and the attachment surface 60 manufactures. The protective cover 31 of the adhesive layer 30 has previously been removed.
  • the attachment surface 60 can be a transparent or translucent surface, e.g. Act glass or transparent plastic, through which a light passage from inside to outside, i.e. in Figure 3 from bottom to top. This allows light to penetrate through the adhesive layer 30, the lower coating 22 and the carrier layer 20 to the outside, as a result of which the areas 21 ′ in which the first coating 21 has been removed are perceived by an observer of the label 10 as illuminated colored areas.
  • a transparent or translucent surface e.g. Act glass or transparent plastic
