Estimating the term…
An ink for the engraved copperplate intaglio printing inks is disclosed, which comprises high-molecular-weight dendritic polymer as a binder component. Inks comprising such polymer can be formulated so as to contain a significantly reduced amount of organic solvent (volatile organic components, VOC) while still being in the appropriate viscosity range required by the intaglio printing process. The printed and cured intaglio ink of the present invention has improved chemical and mechanical resistance properties.
Ink for the copperplate intaglio printing process, comprising a binder, pigment, filler and optionally solvent, the ink having a viscosity in the range of 3 to 60 Pa·s at 40° C., wherein the binder comprises at least one dendritic polymer selected from the group consisting of unsaturated fatty acid modified hydroxyl-functionalized hyperbranched polyesters and wherein the ink further comprises at least one wax or a blend of waxes.
