Polymer coatings have been commonly employed to protect a large variety of materials against photo-aging
as well as to improve the surface properties.The stabilization technologies have been studied actively in material science and photochemistry of polymers.This paper reviews recent developments in photostabilization and photooxidation of polymer coatings.Especially the new trends of hindered amine light stabilizers (HALS) and UV absorbers (UVA)
photoinitiators and multifunctional monomers applied for UV-cured coatings have been emphatically discussed in terms of the reaction characteristic and the photochemical mechanism of photostabilization.
