Abstract

See full text

The present invention provides radiation-curable (UV-curable) inks and coatings for inkjet printing comprising an inert thermoplastic acrylic resin and multifunctional monomers. The inks and coatings can be applied in a single pass printing operation. Furthermore, the inks and coatings are suitable for the printing of food, pharmaceutical and other sensitive packaging materials, particularly of plastic materials. The acrylic polymer (or copolymer) preferably has a molecular weight of 10,000 g/mole, or less, and the ink comprises less than 5 wt % of any blend of monofunctional monomer. The inks and coatings of the invention are particularly suitable for curing by UV-LED radiation.
