<P>PROBLEM TO BE SOLVED: To provide an ink composition excellent in curing ability that offers an image excellent in abrasion resistance, and further to provide an inkjet recording method using the ink composition. <P>SOLUTION: The ink composition includes a photo acid generator (a), a polymerizable compound (b) and a sensitizer (c). The photo acid generator (a) includes a triarylsulfonium salt compound (a-1) having a molar absorption coefficient of 100 or higher in any wavelength between ≥315 nm and ≤400 nm and having substituents at every position of the aryl skeletons, and a photo acid generator (a-2) having a molar absorption coefficient lower than 100 in a wavelength between ≥315 nm and ≤400 nm. <P>COPYRIGHT: (C)2011,JPO&INPIT |
