PHOTOACID GENERATOR COMPOSITION, CATIONICALLY PHOTOPOLYMERIZABLE COMPOSITION, INKJET INK AND INKJET RECORDING METHOD USING SAME

摘要

Disclosed is a photoacid generator composition containing a sulfonium salt compound which does not discharge benzene while being excellent in long-term storage stability. Also disclosed are a cationically photopolymerizable composition containing such a photoacid generator composition, an inkjet ink and an inkjet recording method. The photoacid generator composition is characterized by containing a sulfonium salt having a structure represented by the general formula (1) below and a sulfonium salt other than the sulfonium salt having a structure represented by the general formula (1) below.
