UV photocurable composition containing fluorenylaminoketone photoinitiator, preparation method thereof and fluorenylaminoketone photoinitiator.

摘要

The present invention relates to a fluorenylaminoketone photoinitiator, a method for preparing the same, and a UV photocurable composition containing the fluorenylaminoketone photoinitiator. The photoinitiator includes a compound having a structure represented by the general formula (I) or a derivative compound thereof. The fluorenylaminoketone photoinitiators provided by the present invention can effectively improve the solubility of traditional photoinitiators, reduce the amount of small molecule active diluent used, and increase sensitivity. High, good deep layer hardening effect. This has a good driving effect on promoting photocurable compositions, especially colored ink systems, in the field of photocuring. The UV light curable composition containing the fluorenyl amino ketone photoinitiator of the present invention has high sensitivity, has no residue after development, has good pattern integrity, and has a odorless or low odor coating layer after curing. And excellent yellowing resistance. Embedded image
