A kind of ketoxime ester compound used as photoinitiator, especially a kind of ketoxime ester photoinitiator used as the photocuring material, wherein said ketoxime ester photoinitiator has following general formula (I): wherein R 1 is formula (II), n is the integer of 1ˆ¼4, m is the integer of 1ˆ¼6; R 2 is C1-8 alkyl, phenyl, substituted phenyl, benzyl, or substituted benzyl; R 3 is diphenylthioether group, substituted diphenylthioether group, carbazyl group or substituted carbazyl. The ketoxime ester photoinitiator solves the problems that the existing ketoxime ester photoinitiator such as OXE-1 has bad application performance and bad thermal stability.
