ACTIVE RAY-CURABLE INKJET INK COMPOSITION, ACTIVE ENERGY RAY-CURABLE COMPOSITION, METHOD FOR FORMING IMAGE USING THE SAME, INKJET RECORDER AND TRIARYLSULFONIUM SALT COMPOUND

摘要

PROBLEM TO BE SOLVED: To obtain a triarylsulfonium salt compound that does not release benzene harmful to the human body, has excellent character quality, causes no color mixing and extremely stably records a high-definition image on all recording materials even under various printing conditions, an active ray-curable inkjet ink composition and an active ray-curable composition containing the compound and to provide a method for forming an image using the active ray-curable inkjet ink composition and an inkjet ink recorder.

SOLUTION: The active ray-curable inkjet ink composition comprises an onium salt as a photo acid generator not emitting benzene by active ray irradiation and an oxetane ring-containing compound as a photopolymerizable compound.
