A carbazole oxime ester photoinitiator and the preparation method thereof. The structure of the carbazole oxime ester photoinitiator is shown as the formula ( I ), in which the group R is the aliphatic hydrocarbon group substituted by the cycloalkyl, the cycloalkyl is the aliphatic cycle from cyclopropyl to cyclooctyl; the linking group between the cycloalkyl and the oxime ester group is the linear aliphatic hydrocarbon group, generally, the chain length thereof is 1-5 carbon atoms. The carbazole oxime ester compound with this structure is a new compound, and it has good performance of photoinitiators. |
