ABSTRACT:
An ink composition is provided that includes (A) one type of compound (monomer (A)) selected from the group consisting of a difunctional (meth)acrylic acid ester or amide having an alkylene group of 6 to 12 carbons, and a difunctional vinyl ether having an alkylene group of 6 to 12 carbons, (B) a polymerization initiator, and (C) a colorant. There is also provided an inkjet recording method that includes a step (a) of discharging the ink composition onto a recording medium and a step (b) of irradiating the discharged ink composition with actinic radiation so as to cure the ink composition. Furthermore, a process for producing a lithographic printing plate is provided that includes a step (a′) of discharging the ink composition onto a hydrophilic support and a step (b′) of irradiating the discharged ink composition with actinic radiation so as to cure the ink composition, thus forming a hydrophobic image on the hydrophilic support by curing the ink composition. A lithographic printing plate produced by the process for producing a lithographic printing plate is also provided.
