Definitions

  • the invention is based on a registration metal paper according to the preamble of the main claim.
  • a registration metal paper is described for example in DE-AS 27 48 161.
  • This known recording medium for recording devices has a tape-shaped carrier made of paper or plastic, to which a pigmented lacquer or printing ink layer is initially applied.
  • a burn-out metal layer preferably an aluminum layer, is evaporated onto this intermediate layer.
  • a matting agent for example granules of the materials polystyrene or polyethylene in the form of beads with a grain size between 0.1 / ⁇ m and 10 ⁇ m, is added to the lacquer or printing ink layer .
  • These organic matting agents are present in the paint layer in addition to the pigment soot.
  • the inventive registration metal paper with the characterizing features of the main claim has the advantage that no additional matting agent has to be used to achieve the necessary matting of the surface and that at the same time a significantly higher temperature resistance of the lacquer or printing ink layer is achieved compared to the addition of an organic, flammable matting agent .
  • the coarse grain of the pigments keeps the hot recording electrode away from the lacquer or printing ink film, since the electrode does not slide on the actual lacquer or printing ink surface during recording, but on the outstanding pigments.
  • the term "diameter” in this context generally stands for the grain size the pigments, which are usually not spherical structures.
  • soot agglomerates are added as the pigment, which, in contrast to the primary grain size of soot pigments with a diameter of 0.1 ⁇ m, have a substantially coarser grain size than so-called secondary grains.
  • These soot agglomerates have a diameter of 2 to 20 ⁇ m, preferably the diameter is in the range of about 5 to 15 ⁇ m.
  • the soot portion is preferably 3% by weight.
  • a further improvement of the solution according to the invention results from the fact that other pigments are added to the lacquer or printing ink, so that special effects can be achieved.
  • 10 denotes a paper tape onto which a lacquer or printing ink layer 11 is applied.
  • Pigments 12 and 13 are embedded in the layer 11, with 12 carbon black pigments of different diameters and 13 another pigment.
  • a burnable metal layer 14 preferably an aluminum layer, which is evaporated in a vacuum.
  • the metal layer could also consist of zinc and / or cadmium.
  • the diameter of at least some of the pigments is greater than the thickness of the lacquer or printing ink layer 11.
  • the paper support has a thickness of approximately 50 to 100 / ⁇ m, the thickness of the lacquer or printing ink layer is in the range between 1 and 10 ⁇ m, preferably 2 ⁇ m.
  • the pigments embedded therein consist on the one hand of small soot agglomerates with a diameter of 1.0 ⁇ m, which are completely embedded in the lacquer or printing ink layer.
  • the soot agglomerates used according to the invention, the so-called secondary grains are compressed primary pigments, which are then broken down to the desired grain size in a comminution process.
  • the diameter of the soot agglomerates is in the range between approximately 2 and 20 ⁇ m, preferably in the range between 5 and 15 ⁇ m, with a focus on a diameter of approximately 5 ⁇ m.
  • the proportion of the carbon black pigments is approx. 3% by weight of the wet proportion of the lacquer or printing ink; this proportion can vary in the range from about 0.5 to 5% by weight.
  • the thickness of the evaporated metal layer is between approximately 0.01 and 0.1 ⁇ m, preferably between approximately 0.05 and 0.1 ⁇ m.
  • carbon black 12 of the paint or ink layer in addition to the pigment is carbon black 12 of the paint or ink layer, as another pigment 13 in particular Heliogen be attached, for example meadow one or more of the substances iron oxide, barium sulphate, silicates, nickel titanate or phthalocyanines, having a particle size of about 2 microns to 20 / um.
  • the addition of undyed calcium carbonate causes a certain gray coloration of the black contrast layer due to the soot pigments, which is avoided by appropriate coloring of the calcium carbonate pigment.
  • the coloring or coloring of the calcium carbonate takes place with dyes dissolved in solvents and therefore requires a porous structure of the pigment to be colored.
  • the precipitation of the calcium carbonate from a solution leads to a porous structure which is well suited for staining or dyeing.
  • Another possibility is to precipitate the calcium carbonate in the presence of dark compounds, for example manganese salts.
  • the preceding explanations relate to paper as a carrier material for the record carrier.
  • one more stable plastic carrier to use as a base can be advantageous in the case of special applications.
  • the invention can also be applied in the same way to such a plastic carrier.
  • the coarse-grained pigments also fulfill the function of matting the surface, which is anyway present to a certain extent due to the rougher paper surface, especially in the case of less satin paper.
  • Registration metal paper commonly used today which, as its name suggests, has a paper tape as the carrier material, is provided with a layer of nitrocellulose varnish before vapor deposition.
  • the varnish layer contains fine-grained soot, which provides the blackness required for the contrast and also the micro-roughness required for the legibility and self-cleaning of the electrodes.
  • the hot electrode is kept away from the coating film by suitable pigmentation.
  • suitable pigmentation This is done in that the type, size and number of pigments are selected so that the writing electrode is wholly or partly carried by the pigments protruding from the film while sliding over the surface of the recording metal paper.
  • the hardness of the pigments is selected so that on the one hand the protruding parts of the grains are not removed too strongly by the electrode and that on the other hand the electrodes do not wear out too much.
  • Particularly good results have been achieved with the mixture of different pigments, in particular with a mixture with the carbon black. As a result of this measure, there were practically no more deposits on the electrode or electrodes.
  • Ribbon-shaped material is usually used as the carrier and the finished registration metal paper is then in roll form.
  • the finished registration metal paper is then in roll form.
