HYDROXYPHENYLTRIAZINES

摘要

Compositions based on synthetic organic polymers or prepolymers are effectively stabilized against the damaging effects of light, oxygen and/or heat by addition of a compound of the formula I (see fig. I) in which Z is a group of one of the formulae II or III, (see fig. II) (see fig. III) R7 and R17, independently of one another, are a radical of one of the formulae IV, V and VI (see fig. IV) (see fig. V) (see fig. VI) and the remaining symbols are as defined in claim 1.
