The present invention provides a photoinitiator containing fluorine fluorene oxime esters, a photocurable composition comprising the photoinitiator, and application of the photoinitiator. The photoinitiator has a structure represented by general formula (I) or (II). In the photoinitiator containing fluorine fluorene oxime esters represented by general formula (I) or (II) provided by the present application, the photoinitiator has high initiation efficiency due to the introduction of fluorine-containing groups. Moreover, due to the structural particularity, the photoinitiator further has good surface drying performance, good surface curing effect, non-susceptibility to migration, etc. On this basis, the photoinitiator has non-susceptibility to migration, high initiation efficiency, good surface drying performance, and good surface curing effect, and thus has a wide application prospect. |
