BRIEF DESCRIPTION OF DRAWINGS

FIG. 1 is a ¹H-NMR chart of Sulfonium salt B of the present invention.

Claims

1. A sulfonium salt having a cation represented by Formula (II),

2. A sulfonium salt having a cation represented by Formula (II),

3. A curable composition comprising the sulfonium salt according to claim 1.

4. A curable composition comprising: (a) the sulfonium salt according to claim 1;(b) a polymerizable compound; and(c) a sensitizer.

5. An ink composition comprising the curable composition according to claim 4.

6. The ink composition according to claim 5, wherein it comprises (d) a colorant.

7. The ink composition according to claim 5, wherein it is for inkjet recording use.

8. An inkjet recording method comprising: a step (a1) of discharging an ink composition onto a recording medium; anda step (b1) of irradiating the discharged ink composition with actinic radiation so as to cure the ink composition,the ink composition being the ink composition according to claims 5.

9. The inkjet recording method according to claim 8, wherein the actinic radiation is ultraviolet radiation emitted by a light emitting diode that has a light emission peak wavelength in the range of 350 to 420 nm and generates ultraviolet radiation whose maximum illumination intensity on the surface of a recording medium is 10 to 2,000 mW/cm2.

10. A printed material recorded by the inkjet recording method according to claim 8.

11. A process for producing a lithographic printing plate, the process comprising: a step (a2) of discharging the ink composition according to claim 5 onto a hydrophilic support; anda step (b2) of irradiating the discharged ink composition with actinic radiation so as to cure the ink composition, thus forming a hydrophobic image on the hydrophilic support by curing the ink composition.

12. A lithographic printing plate produced by the process for producing a lithographic printing plate according to claim 11.
