Claim:
A compound of the formula (I): where K a , L, M, N a , O a and P a , independently of one another, are identical or different and are where the symbols and indices have the following meaning: R 3 : H, C 1 -C 22 -alkyl, C 6 -C 14 -aryl, C 5 -C 20 -alkylaryl or C 5 -C 20 -arylalkyl; m: 1, 2, 3, 4, 5 or 6; n and p: independently of one another, identically or differently, 0, 1, 2, 3, 4, 5 or 6; X and Y: CR; Z: CR 2 , —CH═CH—, or —CR 2 ═CR 2 —; R: H, C 1 -C 22 -alkyl (linear, branched or cyclic), or C 6 -C 14 -aryl, R 1 : independently of one another, identically or differently, R, A, B, or C, where where at least one radical R 1 is A, B or C and the number of groups of A, B or C is from 1 to 50 with the total number of groups of A, B and C being up to 50; R 2 is, identically or differently, H or a hydrocarbon radical having 1 to 30 carbon atoms, with the proviso that the following compounds are excluded from formula (I) when (a) O a , K a , M and L simultaneously, R 1 as R, then K a and N a cannot have R 1 as A or B, and (b) O a , K a , M and p simultaneously have R 1 as R, then N a and L cannot have R 1 as A or B.
