Abstract
A stabilizer mixture containing (A) for example a compound of the formula (A-I) 1 wherein R1 is hydrogen or C1-C4alkyl, R2 is a direct bond or C1-C10alkylene and n1 is a number from 2 to 50; (B) a sterically hindered amine compound; and (C) anatase; with the proviso that the component (B) is different from a compound of the formula (A-I).
