HIGH PHOTOSENSIBILITY CARBAZOLE OXIME ESTER PHOTOINITIATOR, PREPARATION AND USE THEREOF

摘要

A carbazole oxime ester-type photoinitiator represented by the following structural formula (I) is disclosed. The photoinitiator has excellent properties in application, especially high photosensibility. The photoinitiator can greatly improve the photocuring properties of photopolymers when applying on them, thus can significantly increase the productivity of photosensitive compositions in application fields such as preparing color filter. The preparation method of the carbazole oxime ester-type photoinitiator and its use in photosensitive composition are also disclosed.
