<P>PROBLEM TO BE SOLVED: To provide an ink composition having high adhesion to a medium to be recorded and giving an image with good quality, an inkjet recording method and printed matter by it and further a planographic printing plate which makes it possible to record an image with a high sensitivity without bleeding and with a high adherence especially to the medium to be recorded and to provide a manufacturing method of it. <P>SOLUTION: The ink composition comprises (a) a cationically polymerizable compound, (b) at least one of diazoketosulfone compounds which generate an acid by irradiation of a radioactive ray, represented by general formula (I):R<SP>1</SP>CO-C(=N)-SO<SB>2</SB>R<SP>2</SP>(I) and optionally (c) a coloring material. Provided that in the formula, R<SP>1</SP>and R<SP>2</SP>each independently represent a substituted or not-substituted alkyl group, a substituted or not-substituted cycloalkyl group or a substituted or not-substituted aryl group. <P>COPYRIGHT: (C)2007,JPO&INPIT |
