<P>PROBLEM TO BE SOLVED: To provide: an ink composition having excellent ink ejection stability and stretching property, curable with high sensitivity by irradiation of radiation rays, and forming an image excellent in rubfastness and blocking resistance; an inkjet recording method using the ink composition; and a printed article. <P>SOLUTION: The ink composition includes (a) a polymer having a siloxane structure and a polymerizable group on a side chain thereof, (b) a polymerizable compound, and (c) a photopolymerization initiator. The polymer (a) having a siloxane structure and a polymerizable group on a side chain thereof preferably further contains, as a copolymerization component, a monomer forming a homopolymer having a glass transition temperature of ≥50°C. The inkjet recording method includes a step of ejecting the ink composition onto a recording medium to be recorded with an inkjet recording apparatus and a step of curing the ink composition by irradiating the ejected ink composition with active radiation rays. <P>COPYRIGHT: (C)2009,JPO&INPIT |
