More Information
Summary:The invention discloses a carbazole oxime ester compound, a preparation method, a composition and an application thereof. The carbazole oxime ester photoinitiator has the characteristics of high sensitivity and ability to absorb long-wavelength light. On the one hand, absorbing long-wavelength light can increase deep curing. On the other hand, it can also avoid competition between other shorter-wavelength ultraviolet light absorbers and photoinitiators in the formulation. The initiation ability of the compound of the present invention in the long wavelength band is stronger than the existing carbazole oxime ester photoinitiator, and can be used alone or in combination with it.
