Definitions

  • the invention relates to a carbonless paper product with two reaction components applied to separate paper surfaces, which can only be brought into contact with one another by pressure.
  • the reaction components namely the color former
  • the color former is present in solution in microcapsules, which are destroyed during the writing process and thus release the color former for the color reaction.
  • reaction components applied with the neutralizing paste migrate into adjacent areas, for example in the case of prolonged storage of the papers, for example into the paper layers above or below them, so that there is an undesirable reduced write-through capability there.
  • the present invention has for its object to provide self-copying papers with areas protected for copying, in which the problems discussed above are avoided.
  • these barrier layers can be applied very easily in the printing process. Since the only requirement is that the barrier layer does not allow the two reaction components to penetrate each other, a wide range of barrier layer materials can be used, the barrier layer preferably being in the form of a lacquer, in particular as is already used today for increasing the color brilliance in multicolor printing, is used. These varnishes often contain UV-curable polymers.
  • the UV curability or the UV drying has the advantage that chemical drying can be achieved within fractions of a second and that there is already complete shielding for the layer below. There is no threat to dimensional stability, which is particularly important for payment transactions in the area of self-copying papers.
  • the barrier layer can not only cover the areas that are covered with color formers, the so-called CB layers, but it is just as possible that normally applied to the front of the carbonless papers to cover the second reaction component with the barrier layer and thus to prevent a reaction between the two reaction components when using the copy sets.
  • both reaction components can also be covered by separate barrier layers.
  • Partial areas of the CB coating are covered with a barrier layer.
  • the CF layer remains accessible over the entire area, but the write-through effect only occurs in those areas in which both the CB and the CF layers are available for the color reaction.
  • the information printed in the partial areas cannot subsequently be identified with a CB reactant, since here the full area on which the CB reactant would be used would lead to a color reaction.
  • This alternative can be selected if, under certain circumstances, there is a need to make the information that was initially not visible in the sub-areas visible later. Spraying the CB layer with the CF reaction component would then make the writing or information recognizable.
  • the covering of the CF and / or the CB layers can also be used for those fields on the copy sets in which no information is normally applied.
  • the purpose of the application of the barrier layer is to keep these fields as labeling fields for machine-readable data free of any optical changes. This is particularly interesting in the case of barcodes and in the very widespread document reading process, for example in payment transactions.
  • the present invention in particular avoids the possibility of chemical components emigrating, which could reduce the color reaction in the areas still suitable for labeling, and in particular the invention can be used for producing absolutely tamper-proof copy documents.
  • the invention also offers great advantages in the use of carbonless forms in payment transactions, in which the automated document reading processes have become very important, but only lead to great progress in rationalization if it can be ensured that the by far largest number of documents to be read in their Readability is not changed and impaired by the normal handling of the documents.
  • the barrier layer does not have to be specifically aligned with the compatibility of the individual papers. This means that different types of paper, in particular papers with different color former systems, can be processed with the same barrier layer material.
  • UV varnishes described below as barrier materials can be applied by any printing process and cured using commercially available UV dryers.
  • UV varnishes are based on a preparation of mono- and polyacrylates of polyols, modified acrylates, organic photoinitiators as well as common aids, e.g. Surfactants.
  • the coating weight with the barrier coating varnishes was varied in the range from 6 to 12 g / m2, the best results being achieved with a coating weight of approx. 10 g / m2.
  • a commercial CF paper was printed in the wet offset process with approx. 10 g / m2 UV varnish in some areas, whereby the varnishes available under the trade name SICPA ® UV overprint varnish 806181 and SICPA ® UV gloss varnish 806182 could be used equally.
  • the paper was dried in a conventional UV dryer.
  • the barrier layer reliably separates the two reaction components from one another.
  • a commercial CB paper was also printed with 10 g / m2 UV varnish using the wet offset process, in turn varnishes which are available under the trade name SICPA ® UV overprint varnish 806181 and SICPA ® UV gloss varnish 806182 were used.
  • a commercial CFB paper was printed with 10 g / m2 UV varnish in some areas using the wet offset process, again using the SICPA ® UV overprint varnish 806181 and the SICPA ® UV gloss varnish 806182.
  • the carbon copy sample again shows minor traces of writing on the protected copies or copies, and these papers are in any case so protected that manipulation can no longer lead to the traces being made visible.
  • the drawing shows a schematic illustration of a set of forms, designated overall by reference numeral 10, which, in addition to a cover sheet 12, comprises a middle sheet 14 and a last sheet 16.
  • the cover sheet 12 has on its rear side 18 a so-called CB coating, which comprises a color former dissolved in a core solvent and enclosed in microcapsules.
  • the color former or dye precursor is usually the leuco form of a dye and forms a first reaction component.
  • the middle sheet 14 has on its front side 20 a so-called CF coating which contains a component which is able to convert the leuco dye into the dye form.
  • the back 22 of the middle sheet 14 in turn carries a so-called CB coating, which is identical in terms of composition to the coating of the back 18 of the cover sheet 12.
  • the front coating of the last sheet 16 again corresponds to the front coating of the middle sheet 14, so that when the cover sheet 12 is labeled, the information is written through the interaction of the encapsulated dye precursors with the reaction component of the CF coating on the middle and last sheets 16. since the pressure exerted by the application of the information causes the microcapsules to break along the writing track and release the dye precursor and react with the second reaction component of the CF coating.
  • the corresponding fields 24 ', 26', 24 '' and 26 '' are coated according to the invention with a barrier layer, in the present case in each case on the front side, which prevents the core solvent emerging from the capsules from having the dye precursor with the second reaction component, which is present in the CF coating of sheets 14 and 16 comes into contact.
  • the trace of the writing can be added afterwards be made visible by applying the second reaction component there to the microcapsules broken along the writing track.
  • the information is completely masked out and, in addition, the certainty that the copied information cannot subsequently be made visible through manipulations and thus possibly get into the wrong hands.
