ELECTRON BEAM-CURABLE INKJET INKS AND USE THEREOF IN INKJET PRINTING METHODS

摘要

The invention relates to electron beam-curable inks which contain 10 to 40% by weight of oligomer, 30 to 89% by weight of reactive diluent and 1 to 15% by weight of pigments, and are free of photoinitiators. The invention likewise relates to a printing method wherein electron beam-curable inks are applied to a substrate surface by means of inkjet technology and then cured by the action of an electron beam. The inventive inks and methods can be used for printing of articles in health-critical areas, such as food and drink packaging and children's toys.
