PROBLEM TO BE SOLVED: To provide an ultraviolet curable ink-jet ink composition which realizes low viscosity and excellent curability.SOLUTION: An ultraviolet curable ink-jet ink composition comprises: a monomer A represented by the general formula (I) defined by CH=CR-COOR-O-CH=CH-R, where Ris a hydrogen atom or a methyl group, Ris a C2-20 divalent organic residue, Ris a hydrogen atom or a C1-11 monovalent organic residue; at least one monomer B selected from the group consisting of monomers represented by the general formula (II) defined by CH=CR-COO-R-R, where Ris a C0-2 linear or branched alkylene group, and Ris an aromatic ring, a 5-6 membered cyclic saturated hydrocarbon, or a 5-6 membered cyclic ether having one oxygen atom; and a photoinitiator. The content of the monomer A is 15-60 mass% based on the total mass of the ink composition, and the content of the monomer B is 10-50 mass% based on the total mass of the ink composition.SELECTED DRAWING: None |
