Photopolymerizable inkjet ink, printing coating method, printing coating, composition container, and printing coating equipment

摘要

PROBLEM TO BE SOLVED: To provide a photopolymerizable inkjet ink excellent in curing properties even if an ultraviolet light-emitting diode (UV-LED) light source is used, while having low skin sensitization properties.SOLUTION: A photopolymerizable inkjet ink at least includes: a polymerizable monomer being at least one of a methacryloyloxy ethyl acrylamide and a glycerol dimethacrylate monoacetate; and a photoinitiator having an absorption sensitivity at wavelength 365-395 nm. The photoinitiator is preferably one kind selected from an α-aminoketone compound, an acylphosphine oxide compound and a thioxanthone compound.SELECTED DRAWING: None
