  • Coumarin oxime ester compounds, preparation and use thereof
    Patent number: 11142511
    Abstract: The present invention relates to a coumarin (keto) oxime ester compound of formula (I), wherein n and R1, R2, R3, R4, R5, R6, and R7 are as defined in the specification. The compound has strong ultraviolet absorption in the range of 300 to 450 nm. After absorbing light energy, it can quickly transfer energy and continuously initiate polymerization. It has obvious advantages in terms of photosensitivity and pattern integrity, and is very suitable for radiation curing by UV-LED light source. In addition, the compound of formula (I) also has good thermal stability. The present invention also relates to a method for preparing the compound of formula (I) and use of the compound. The compound is suitable as a photoinitiator in a UV-LED light curing system and is suitable for the radiation wavelength of UV-LED light curing.
