摘要：

The lifetime of organic coatings is reduced in outdoor applications by attacks of solar radiation, oxygen and atmospheric pollutants. Undesirable mechanical, physical and chemical consequences of the resulting degradation can be substantially restricted by properly selected photostabilizers. Structures of absorbers of UV radiation (UVA) and photoantioxidants (hindered amine stabilizers, HAS), mechanisms of their activity, processes responsible for loss of their durability, interferences with other coating components (catalysts, pigments, extenders) and application in various coatings are outlined.
