It is found that synergistic effects based on combined use of HALS (hindered Amine Light Stabilizers) with phenolic antioxidants consist of the action of HALS as hydrogen donor to quinones, derived from the phenol in autoxidation, excited by uv light. The finding has been realized as a new photostabilizer of hydrogenated benzoin derivatives. They are generally characterized by multifunctions. The o,o`-dihydroxyl-substituted derivatives inter alia extend the life of a phenolic antioxidant co-used, as hydrogen donor, as well as ultimately act as uv absorber.
