Title:
COUMARIN OXIME ESTER COMPOUND AND PREPARATION AND USE THEREOF
Document Type and Number:
WIPO Patent Application WO/2019/019792
Kind Code:
A1
Abstract:
The present invention relates to a coumarin (ketone) oxime ester compound of formula (I), wherein the n and R1, R2, R3, R4, R5, R6 and R7 are as defined in the description. The compound has a very strong ultraviolet absorption in a range of 300-450 nm. Energy transfer can occur rapidly after absorbing light energy and polymerization is continuously initiated. The compound has obvious advantages in terms of photosensitivity and pattern integrity and is very suitable for the radiation curing of UV-LED light sources. In addition, the compound of formula (I) also has a good thermal stability. The present invention also relates to a preparation method for the compound of formula (I) and uses of the compound. The compound is suitable as a photoinitiator in a UV-LED photocuring system and is suitable for radiation wavelengths of the UV-LED photocuring.
