FAST-CURING UV INKJET INKS BASED ON HYPERBRANCHED POLYESTER ACRYLATES

摘要

PROBLEM TO BE SOLVED: To provide a fast-curing UV inkjet inks based on hyperbranched polyester acrylates.SOLUTION: The present invention relates to a fast curing UV inkjet inks based on hyperbranched polyester acrylates. The ink according to the invention is characterized in that it contains the following components: 1 mass% to 20 mass% of at least one hyperbranched polyester acrylate having functional groups in the range of 6 to 30; 1 mass% to 30 mass% at least one reactive diluent; 1 mass% to 20 mass% of at least one free-radical photoinitiator of the Norrish type I; 30 mass% to 70 mass% of at least one multifunctional (meth)acrylate monomer; and 0 mass% to 30 mass% of at least one monofunctional (meth)acrylate monomer. The invention further relates to a method for inkjet printing, using the ink of the invention.SELECTED DRAWING: None
