A latent curing system was necessary for the anisotropic conducting film (ACF), and a fast reaction system was also necessary to fast production. In this study, the benzylsulfonium salts were synthesized and were used as latent curing initiators for epoxy resin. These benzylsulfonium compounds exhibited a long shelf life with epoxy resin. The curing behaviors of an epoxy resin with these sulfonium salts were investigated using differential scanning calorimetry (DSC), and the curing times were determined at $150^{\circ}C$ using an indentation method.
