In order to reduce the migration of photoinitiators in UV-curable coating，two polymerizable oxime ester photoinitiators with double bond end capping were synthesized usingcarbazole as the chromophore. The UV absorption，steady-state photolysis and migration were studied by UV-visible spectroscopy，the decarboxylation and photopolymerization were characterized by Fourier Transformed Infrared（FT-IR）， and the thermal stability was determined by Thermo-Gravimetric Analysis（TGA）. The results showed that the maximum absorption wavelength ofthese photoinitiators was at 338 nm，with a tail absorption extending to 380 nm. Under low-intensity 365 nm LED irradiation（1 mW/cm²），the carbazole-based oxime esters could undergo decarboxylation reaction，and the released active free radicals could effectively initiatepolymerization of acrylate monomers and thiol acrylate systems. Migration tests indicated that bothpolymerizable carbazole-based oxime esters exhibit low migration in photo-cured coatings.
