Abstract
An ink composition which is used for active energy ray-curable inkjet printing, has excellent curability or adhesiveness to multiple base materials while having low viscosity, and exhibits excellent non-yellowing properties of the printed matter is provided. The composition comprises a polymerizable monomer (A) and photopolymerization initiators (B), the polymerizable monomer comprising 2-(2-vinyloxyethoxy)ethyl acrylate (A-1), and the photopolymerization initiators comprising oligo(2-hydroxy-2-methyl-1-(4-(1-methylvinyl)phenyl)propanone) (B-1) and other initiator (B-2).
Claims7
