Title:
OXIME ESTER PHOTOINITIATOR, PREPARATION METHOD THEREFOR AND USE THEREOF
Document Type and Number:
WIPO Patent Application WO/2024/021979
Kind Code:
A1
Abstract:
The present application provides an oxime ester photoinitiator, and a preparation method therefor and the use thereof. The oxime ester photoinitiator has a structure as shown in general formula (I), wherein R1 and R2 are each independently selected from a substituted or unsubstituted C1-C20 alkyl, a substituted or unsubstituted C3-C20 cycloalkyl, a substituted or unsubstituted C6-C20 aryl, a substituted or unsubstituted C4-C20 heteroaryl, and a substituted or unsubstituted C3-C20 cycloaliphatic heterocyclic group; m is 1 or 0, n is 1 or 0, x is 1 or 0, y is 1 or 0, and z is 1 or 0. The oxime ester photoinitiator of the present application has a diketone oxime ester structure and asymmetric substituents, and has a delocalization structure. Compared with an existing similar photoinitiator, the oxime ester photoinitiator has significantly improved solubility, can take both high sensitivity and low yellowing into consideration when applied to a photocurable composition, and has good application prospects.
