摘要：
Disclosed is the use of silane and siloxane bis(biphenyl)triazine derivatives of formula (1), wherein n is a number from 1 to 4; if n=1, X is *-L-Sil; or a radical of formula (11′), L is a linker selected from a radical of formula (2); R1, R2, R3 independently from each other are C1-C22alkyl; C6-C20aryl; C1-C22alkoxy; or O—C6-C20aryl; R4, R5, R6 and R7 independently from each other are hydrogen; C1-C22alkyl; C6-C20aryl; C1-C22alkoxy; or O—C6-C20aryl; b is a number from 0 to 30; c is a number from 0 to 6; and d is a number from 0 to 1; p is a number from 1 to 250; q is a number from 0 to 250; and Sil, Sil1 and Sil2 independently from each other are a silane-, oligosiloxane or polysiloxane moiety; if n=2, X is a bivalent radical of formula (1a); or (1b); x is a number from 2 to 250; y is a number from 0 to 250; and z is a number from 1 to 50; if n=3, X is a trivalent radical containing a silane-, oligosiloxane or polysiloxane moiety; If n=4, X is a tetravalent radical of formula (1c); and A is a radical of formula (111′) as UV absorbers.
