<P>PROBLEM TO BE SOLVED: To provide an ink composition which can be polymerized and cured, by irradiating active energy rays after recording, has high sensitivity to the active energy rays, and excellent curability. <P>SOLUTION: This ink composition is characterized by comprising a cation-polymerizable compound, a compound represented by the general formula (I) (R<SP>1</SP>, R<SP>2</SP>, R<SP>3</SP>and R<SP>4</SP>are each independently H, a 1 to 20C alkyl, a non-substituted or hydroxy-substituted 1 to 20C alkoxy, provided that at least one of R<SP>1</SP>, R<SP>2</SP>, R<SP>3</SP>and R<SP>4</SP>is not H; X<SP>-</SP>is a non-nucleophilic anion), and an anthracene compound. <P>COPYRIGHT: (C)2007,JPO&INPIT |
