<P>PROBLEM TO BE SOLVED: To obtain an ultraviolet-curable ink-jet ink composition having excellent fixing properties to a non-absorbent material such as plastic, metal, etc. <P>SOLUTION: The ultraviolet-curable ink-jet ink composition comprises at least pigment, an ultraviolet-curable resin and a photopolymerization initiator. The ultraviolet-curable resin contains a phosphorus-based compound. The ultraviolet-curable resin containing a phosphorus-based compound preferably contains an acryloyl group or a methacryloyl group and is at least one selected from triacryloyloxyethyl phosphate, (2-hydroxyethyl)methacrylate acid phosphate and phosphoric acid mono(2-hydroxyethyl)methacrylic ester. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
