The photocrosslinking of the diacrylate (HDDA)-short oils alkyde in the presence of different photoinitiators have been studied. The curing process was followed by infrared spectroscopy, insolubilization and hardness measurements. The decay of the photoinitiator during the process was followed by UV spectroscopy. The photocrosslinking of the HDDA-short oil alkyde system was the fastest and the properties of the UV-cured product was the best in the presence of D-1173 photoinitiator.
