Title:
OXIME ESTER PHOTOINITIATOR OF CHALCONE STRUCTURE, PREPARATION METHOD THEREFOR AND APPLICATION THEREOF
Document Type and Number:
WIPO Patent Application WO/2022/237644
Kind Code:
A1
Abstract:
The present invention provides an oxime ester photoinitiator of a chalcone structure, a preparation method therefor and an application thereof. The initiator has the following structure: Ar1, wherein Ar2 is a substituent containing an aromatic ring or a heteroaromatic ring, and R1 is C1-C20 linear or branched alkyl, C3-C20 cycloalkyl, C3-C8 cycloalkyl-substituted C1-C10 alkyl, C1-C20 alkyl-substituted C3-C8 cycloalkyl, C6-C20 aryl, C1-C5 alkyl-substituted C6-C20 aryl, C4-C20 heteroaryl, or C1-C5 alkyl-substituted C6-C20 heteroaryl. The oxime ester photoinitiator of the chalcone structure has a large conjugated structure and excellent sensitivity, is difficult to migrate after curing, and has excellent yellowing resistance. In addition, the photoinitiator also has the characteristics of simple synthesis, no need of expensive catalyst in the synthesis process, excellent curing speed and the like, and can be widely applied to the field of photocuring.
