The photocation-curable ink according to the present invention uses a 2,2,6,6-tetramethylpiperidine 1-oxyl free radical or a compound including a 2,2,6,6-tetramethylpiperidine 1-oxyl free radical structure; wherein molar concentration of the 2,2,6,6-tetramethylpiperidine 1-oxyl free radical or the 2,2,6,6-tetramethylpiperidine 1-oxyl free radical structure in the ink is 19.6 mM to 39.2 mM. Accordingly, it is possible to obtain the photocation-curable ink having the high adhesion performance with respect to the printing medium.Type: ApplicationFiled: December 4, 2009Publication date: June 10, 2010Applicant: BROTHER KOGYO KABUSHIKI KAISHAInventors: Akiko NOGUCHI, Yuki MIURA, Atsushi NARUSE
