摘要

The mixtures contain (a) at least one sterically hindered amine of the formula (I) <IMAGE> in which R<1> and R<2> are H, methyl or phenyl, and a further component from the groups (b) UV absorbers and/or (c) antioxidants from the classes consisting of sterically hindered phenols, phosphites and/or vitamin E or derivatives thereof. The mixtures are distinguished by a good light-stabilisation action in polyurethanes.
