摘要

Use of a nitrogen containing hetero aromatic compound (I) and/or its derivatives for the protection of inanimate organic materials before damaged by the effect of light, oxygen and/or heat. Use of a nitrogen containing hetero aromatic compound of formula (I) and/or its derivatives for the protection of inanimate organic materials before damaged by the effect of light, oxygen and/or heat.
