<P>PROBLEM TO BE SOLVED: To obtain an ink composition for inkjet recording, which has high sensitivity to radiation exposure, forms a high-quality image and has excellent storage stability and to provide a method for manufacturing a planographic printing plate, which eliminates the need for development and forms an image having high printing durability and high image qualities. <P>SOLUTION: The ink composition for inkjet recording comprises at least a colorant, a polymerizable compound and a polymerization initiator having a polymerizable structure, especially a structure represented by general formula (I) (R<SP>a</SP>and R<SP>b</SP>are each independently a hydrogen atom, a halogen atom, a cyano group or an organic group; Z is CN or COY; X is a group bonded through a hetero atom to an α carbon or a halogen atom; Y is a group bonded through a hetero atom to a carbonyl group or a halogen atom) in the molecule and is curable by radiation exposure. <P>COPYRIGHT: (C)2007,JPO&INPIT |
