  • non-white pigment is used in the context of the invention, then this should preferably be one which is largely similar to the symbols to be covered, in particular characters. These are regularly blue, black, red or green. In general, the yellow hue will therefore have to be excluded. Black pigments, in particular carbon black, are particularly preferred in practical applications.

Will the crowd less than 0.1% by weight of non-white pigments in both layers falls below, then the desired effect is not to the desired extent achieve. However, if the amount of 5% by weight is exceeded, none will be significant improvement achieved more. Exceeding can also e.g. in the Connection with the pressure-sensitive adhesive layer leads to its adhesive ability is affected. To preserve the functional requirements, there should be a value here of about 3.5 are not exceeded.
  • the transfer layer is "white pigmented".
  • white pigmented means that it contains the usual white pigments in the required amount in order to To impart a certain opacity to the transfer layer.
  • These include in particular Titanium dioxide (titanium white), as well as precipitated chalk, clay and / or colloidal Silicas. In the context of the invention, this does not preclude them from being additionally suitable different colored pigments is tinted.
  • This tinting can be done by Incorporation of suitable amounts of black pigment, especially carbon black, but also by tinting with other pigments, for example yellow and green.
  • This Tinting may be required if there is a color match to the substrate Characters etc. should be covered, must be done.
  • the comments on Particle size made in connection with the "non-white pigments" apply here accordingly.
  • the choice of the respective Binder to form the transfer layer also the type of used plasticizer are considered. This should be when applying the Transfer layer on the area to be corrected or covered not by the normally thinly formed PSA layer penetrate and with the correcting point or the colorants located there and in this way cause an undesirable coloring of the transfer layer.
  • plasticizers such as silicone, castor and mineral oils serve this purpose suitable.
  • plasticizers such as for example phthalic acid esters or oleic alcohol are not equally good suitable.
  • the binder-containing transfer layer can be a so-called "Laking agent” are incorporated, the possibly migrating colorant fails or insoluble, so that it does not enter the applied transfer layer migrate and color them again.
  • Suitable varnishes are tannin and Tannin derivatives.

  • the binder selected in each case is used to form the transfer layer preferably as an aqueous solution or dispersion.
  • the additives discussed below added are discussed below added.
  • the choice of the appropriate solvent or dispersant depends on the type of binder used. For this include in particular low to medium-boiling organic solvents from the group of Alcohols such as ethanol, isopropanol and butanol, the ketones such as acetone and Methyl ethyl ketone, the ester, such as methyl and ethyl acetate, the aromatic Hydrocarbons such as toluene, the aliphatic hydrocarbons such as gasoline Boiling range from 70 to 140 ° C, alone or in a mixture, but especially water, alone or in a mixture with low-boiling, water-soluble organic solvents.
  • the concentration of the binder in the solution or dispersion is not essential to the invention.
  • a rough guideline can be that it is between about 3 and 15% by weight, with the range of about 6 to 12% by weight being preferred.
  • the solution or dispersion is preferably applied to the auxiliary carrier in an amount of about 15 to 25 g / m 2 (dry weight) and very particularly preferably between about 18 and 22 g / m 2 .

  • the pressure sensitive adhesive layer can consist of commercially available pressure sensitive adhesives. These are elastic and permanently adhesive self-adhesive compositions with great adhesive forces that adhere immediately to the various surfaces even under low pressure at room temperature. They are preferably applied in aqueous dispersion to the transfer layer and, if appropriate, the intermediate layer already on the auxiliary carrier, since the layers already formed are not dissolved again. Among pressure-sensitive adhesives of this type, those based on acrylate are particularly advantageous.
  • the starting materials can be viscous solutions and dispersions based on rubber, polyacrylates, polyvinyl ethers or polyvinyl isobutylene. Commercial materials based on polyacrylates are preferred.
