PROBLEM TO BE SOLVED: To provide an ultraviolet-curable ink composition that has low viscosity, excellent adhesion, and suppressed contractility.SOLUTION: An ultraviolet-curable inkjet ink composition comprises: a compound of 20-70 mass% relative to the total mass of the ink composition, represented by the general formula (I): CH=CR-COOR-O-CH=CH-R(where Ris a hydrogen atom or a methyl group, Ris a C2-C20 divalent organic residue, Ris a hydrogen atom or a C1-C11 univalent organic residue); and at least one of a polymerizable compound having an alicyclic structure in a molecule and a polymerizable compound having a cyclic ether structure in a molecule, of 10-20 mass% relative to the total mass of the ink composition.SELECTED DRAWING: None |
