Abstract
(DE)
Die Erfindung betrifft eine Drucktinte, vorzugsweise Tintenstrahltinte, enthaltend Perlglanzpigmente und mindestens ein Lösemittel und/ oder mindestens eine strahlungshärtbare Komponente und/ oder mindestens ein Bindemittel, wobei die Perlglanzpigmente ein weitgehend transparentes plättchenförmiges Substrat mit einer Dichte ρS und mindestens einer optisch wirksamen Beschichtung mit einer Dichte ρM umfassen und die Perlglanzpigmente einen d90-Wert der Summenhäufigkeitsverteilung der volumengemittelten Größenverteilungsfunktion aus einem Bereich von 3,5 bis 15 μm aufweisen. Weiterhin betrifft die Erfindung ein Verfahren zur Herstellung dieser Drucktinte, vorzugsweise Tintenstrahltinte.
(EN)
The invention relates to a printing ink, preferably a ink-jet ink, containing pearlescent pigments and at least one solvent and/or at least one radiation-curable component and/or at least one binder, wherein the pearlescent pigments comprise a substantially transparent plate-shaped substrate having a density ρS and at least one optically active coating having a density ρM, and the pearlescent pigments have a d90 value of the cumulative frequency distribution of the volume-averaged size distribution function from a range of 3.5 to 15 μm. The invention further relates to a method for producing said printing ink, preferably ink-jet ink.
(FR)
L'invention concerne une encre d'impression, notamment une encre d'impression à jet d'encre contenant des pigments à effet perlescent et au moins un solvant et/ou au moins un constituant durcissable par rayonnement et/ou au moins un liant, les pigments à effet perlescent contenant un substrat en forme de plaquette sensiblement transparent ayant une densité ρS, et au moins un revêtement à effet optique ayant une densité ρM. Les pigments à effet perlescent ont une valeur d90 de distribution de fréquences cumulées de la fonction de distribution de taille moyenne en volume comprise entre 3,5 et 15. L'invention concerne également un procédé de préparation de cette encre d'impression, de préférence de cette encre d'impression à jet d'encre.
