<P>PROBLEM TO BE SOLVED: To provide an ink composition having greatly enhanced preservation stability, exhibiting high curing sensitivity and giving an image of good image qualities, an inkjet recording method and a printed matter, and to provide a lithographic printing plate capable of recording an image free from blotting, highly sensitive, and exhibiting high adhesion to a recording medium and a manufacturing method thereof. <P>SOLUTION: The ink composition comprises (a) a cationically polymerizable compound, (b) a compound generating an acid by radiation irradiation, and (c) at least one acid crosslinking agent selected from among compounds represented by general formulae (I)-(III) and alkoxymethylated melamine compounds. In general formula (I), R<SP>1</SP>is each independently a hydrogen atom, a substituted or unsubstituted alkyl group, or a substituted or unsubstituted acyl group; R<SP>2</SP>-R<SP>5</SP>are each independently a hydrogen atom, a hydroxy group, a substituted or unsubstituted alkyl group, or a substituted or unsubstituted alkoxy group; and X is a single bond, a methylene group or an oxygen atom. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
