A hybrid photosensitive resin having a structure represented by general formula (I) and contains an oxetanyl functional group and a (meth)acryloxy functional group. The functional groups are coordinated with each other and the functionality is adjustable and controllable. The hybrid photosensitive resin is highly suitable for radical-cation photocuring systems, there is no problem of polymerization inhibition by oxygen, and its cured film has high hardness, good flexibility, excellent adherence, and excellent heat resistance.
