  • Intaglio printing ink comprising dendrimers
    Patent number: 8540813
    Abstract: 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.
