Abstract
The present invention relates to oxygen-substituted sterically hindered amines of the formulae I or II: (II), wherein, for example, F2, R3, R5, R6, R8, R9, R11, R12, R13, R14 are n-butyl; Z1 to Z10 are propoxy and R1, R4, R7, R10, R13 are 2,2,6,6-tetramethyl-1-propoxy-piperidin-4-yl. Compositions comprising compounds of formulae I or II and an organic material, which is susceptible to oxidative, thermal or light-induced degradation, are further disclosed. Optionally, further additives are contained.
