<P>PROBLEM TO BE SOLVED: To provide an ink composition which has high discharge stability from an inkjet head of an ink, cures with high sensitivity by irradiation with radiation, can form a high quality image, and excels in the adhesion on to a medium to be recorded and storage stability, an inkjet recording method using the ink composition, a good quality print, a lithographic printing plate, and a method for producing a lithographic printing plate. <P>SOLUTION: The ink composition comprises (a) a polymerizable compound, (b) a polymerization initiator, (c) a colorant, and (d) at least one organic solvent having a dielectric constant of 7 or more. The inkjet recording method comprises discharging this ink composition and thereafter irradiating the discharged ink composition with active radiation to cure it. The print is recorded by this recording method. The method for producing a lithographic printing plate comprises imagewise discharging the above ink composition on a hydrophilic support to form a hydrophobic image, and the lithographic printing plate is produced by this method. <P>COPYRIGHT: (C)2007,JPO&INPIT |
