CA 2728878

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) whilst 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.

L'encre ci-décrite pour l'impression intaglio sur plaques de cuivre gravées comprend un polymère dendritique de poids moléculaire élevé à titre de composant liant. Les encres comprenant ce type de polymère peuvent être formulées de manière à contenir une quantité significativement réduite de solvant organique (composants organiques volatils, VOC) tout en restant dans la plage de viscosité appropriée requise par le procédé d'impression intaglio. L'encre intaglio imprimée et durcie selon la présente invention a des propriétés de résistance chimique et mécanique améliorées.
