Applies FT‐IR spectroscopic techniques to study the degradative process occurring on ageing/UV irradiation of lac resin. Unequivocally concludes that hydroperoxidation and inter‐etherification reactions are more likely to occur during the degradative process. MS(FAB) and solubility studies also support FT‐IR studies. Establishes that lac resin is remarkably stable to long wavelength UV radiation but tends to undergo prominent degradation on exposure to short wavelength UV irradiation.
