The present invention provides a sulfonium salt photoinitiator and a method for producing the same, a photocurable composition containing the same, and an application thereof. The sulfonium salt photoinitiator has the structure represented by the formula (I). By modifying the structure of the conventional sulfonium salt photoinitiator, a sulfonium salt photoinitiator having a new structure can be obtained. When applied to a photocurable composition, it can exhibit higher photosensitivity, has excellent solubility, low odor, and low toxicity, and is clearly superior to conventional photoinitiators of the same type. ing. |
