Abstract: The photochemical properties of eight novel water-soluble thioxanthone photoinitiators were studied by UV absorption, fluorescence and ESR. The maximal UV absorption wavelength and extinction coefficient, fluorescence quantum yield and the signal intensity of ESR were determined. The relationship between the structure and the photochemical properties was also discussed.

Key words: thioxanthone, photoinitiator, electron spin resonance
