Title:
ETHER-FUNCTIONALIZED COUMARIN OXIME ESTER COMPOUND, AND PREPARATION AND USE THEREOF
Document Type and Number:
WIPO Patent Application WO/2024/067718
Kind Code:
A1
Abstract:
The present invention relates to an ether-functionalized coumarin oxime ester compound of formula (I), wherein the variables therein are as defined in the description. The compound has good photosensitive absorption in the range of 300-550 nm, especially in the range of 365-450 nm; after absorbing light energy, the compound can rapidly undergo a photochemical reaction, initiate the polymerization of polymerizable monomers within several seconds, and complete a polymerization reaction within 10 minutes (especially in 3 minutes); and the compound has significant advantages in the aspect of photosensitivity, and has good thermal stability, storage stability and solubility, thus being applicable as a photoinitiator for curing with a UV-VIS LED light source. The present invention further relates to a preparation method for and the use of the ether-functionalized coumarin oxime ester compound of formula (I). The compound can serve as a photoinitiator and is particularly applicable to curing with a UV-VIS LED light source.
