Definitions

  • the ink additionally has a so-called inhibitor, which prevents or slows down the crosslinking of the polymeric binder by means of the crosslinker until the ink is applied to the substrate provided for the ink jet printing.
  • a so-called inhibitor which prevents or slows down the crosslinking of the polymeric binder by means of the crosslinker until the ink is applied to the substrate provided for the ink jet printing.
  • This approach has the advantage that the ink has high storage stability due to the presence of the inhibitor until the ink is actually used and applied to the substrate by ink jet printing.
  • crosslinking of the ink in the printhead itself can be safely prevented by the presence of an inhibitor of crosslinking until the ink is on the substrate itself.
  • the inhibitor in the ink can then lose its inhibiting effect, for example, by having a comparatively low boiling point and correspondingly evaporating / vaporizing.
  • the inhibitor may also lose its action in other ways, for example by contact with atmospheric oxygen or by application of temperature above a corresponding limit.
  • the present in the ink solids, in particular the pigments and binder particles are present with a relatively small particle size.
  • the ink which is usually in the form of a dispersion, can advantageously be discharged from the print head of the inkjet printer.
  • the polymeric binder is present in the ink with a particle size of ⁇ 500 nm, in particular with a particle size of ⁇ 200 nm.
  • the described method is preferably characterized in that the surface of the corresponding substrate is coated or printed without chemical pretreatment, ie without application of an agent which chemically changes the surface.
  • the surface of the corresponding substrate without Coated or printed on the aid of a primer which, as a so-called primer, chemically prepares the surface in such a way that permanent coating or printing is made possible.
  • Comparative Example 2b Binder Thyon SF1 (Ecronova Polymer GmbH, Germany)
  • the examples including the comparative examples, show that the water-based inks having the claimed features of claim 1 and the preferred subclaims surprisingly result in durable coatings and imprints on the respective substrates when applied by the ink jet printing process.

Abstract

La présente invention concerne une encre aqueuse pour impression à jet d'encre qui comprend au moins un pigment, au moins un liant polymère réticulable, au moins un agent de réticulation et au moins un solvant organique ainsi que de l'eau. À cet effet, l'invention prévoit comme liant polymère réticulable au moins un polymère choisi dans le groupe comprenant le caoutchouc acrylonitrile-butadiène (NBR), le caoutchouc acrylonitrile-butadiène-styrène (ABS), le copolymère de méthacrylate-butadiène-styrène (MBS) ou le copolymère de méthacrylate de méthyle-butadiène-styrène (MBS). Concernant le liant polymère, il s'agit de préférence d'un liant polymère autoréticulable. De préférence, l'encre selon l'invention peut en outre présenter un inhibiteur qui empêche ou ralentit la réticulation du liant polymère jusqu'à ce que l'encre soit appliquée sur le substrat prévu pour l'impression à jet d'encre.
