Document Type and Number:
WIPO Patent Application WO/2022/068871
Kind Code:
A1
Abstract:
The present invention relates to a bifunctional coumarin oxime ester photoinitiator of formula (I), the variables thereof being as defined in the description. The compound has very strong ultraviolet absorption in the 300-550 nm range and, after the light energy is absorbed, can rapidly implement energy transfer and continuously initiate polymerisation, having obvious advantages in terms of photosensitivity and pattern integrity, and being very suitable for (UV-vis) LED light source radiation curing. In addition, the compound of formula (I) also has good thermal stability and solubility. The present invention also relates to a preparation method for the compound of formula (I) and a use for said compound, the compound being suitable for use as a photoinitiator in a (UV-vis) LED photocuring system, and being suitable for the radiation wavelengths of (UV-vis) LED photocuring.
