<P>PROBLEM TO BE SOLVED: To provide an ink composition for inkjet recording, having high sensitivity to active radiation, excellent curability and excellent ejection stability and giving an image having excellent blocking resistance. <P>SOLUTION: The ink composition for inkjet recording contains (A) a polymer having a partial structure selected from the group consisting of a fluorine-substituted hydrocarbon group, a siloxane skeleton and a long-chain alkyl group and a radically polymerizable group on a side chain, (B) a sensitizing dye expressed by general formula (i), (C) a radically polymerizable compound different from the polymer (A), and (D) a radical polymerization initiator. In the formula (i), X is O, S or NR; R is a hydrogen atom, an alkyl group or an acyl group; n is 0 or 1; and R<SP>1</SP>to R<SP>8</SP>are each independently a hydrogen atom or a univalent substitution group. <P>COPYRIGHT: (C)2010,JPO&INPIT |
