Reaction Steps

1-fluoro-4-hydroxy-thioxanthen-9-one (2.5 g, 0.01 mol), 2,6-di-tert-butyl-4-methylphenol (0.07 g, 0.32 mmol) and trifluoroacetic acid (0.1 g=92.4 μL, 1.2 mmol) were added to 2-(2′-vinyloxyethoxy)ethylacrylate (27.6 g). The mixture was heated to 70° C. and stirred for 4 hours. After cooling down to room temperature, activated Lewatit M600 MB (10 g) was added and stirred for 1 hour. After filtration, a 15 w % solution of acrylic acid 2-{2-[1-(1-fluoro-9-oxo-9H-thioxanthen-4-yloxy)-ethoxy]-ethoxy}-ethyl ester in 2-(2′-vinyloxyethoxy)ethylacrylate was obtained, which was directly used in the radiation curable compositions according to a preferred embodiment of the present invention.
