ABSTRACT:
A compound of the formula (IA) or (IB)whereinG1, G2, G3and G4are independently of one another C1–C18alkyl or C5–C12cycloalkyl or the radicals G1and G2and the radicals G3and G4form independently of one another, together with the carbon atom they are attached to, C5–C12cycloalkyl;R is hydrogen C1–C18alkyl, C1–C18hydroxyalkyl, C2–C18alkenyl, C5–C12cycloalkyl, C7–C12phenylalkyl unsubstituted or substituted on the phenyl radical by C1–C4alkyl and/or C1–C4alkoxy; or C1–C18alkanoyl;R* is hydrogen, C1–C18alkyl, oxyl, —OH, —CH2CN, C3–C6alkenyl, C3–C8alkynyl, C7–C12phenylalkyl unsubstituted or substituted on the phenyl radical by C1–C4alkyl and/or C1–C4alkoxy; C1–C8acyl, C1–C18alkoxy, C1–C18hydroxyalkoxy, C2–C18alkenyloxy, C5–C12cycloalkoxy, C7–C12phenylalkoxy unsubstituted or substituted on the phenyl radical by C1–C4alkyl and/or C1–C4alkoxy; C1–C18alkanoyloxy, (C1–C18alkoxy)carbonyl, glycidyl or a group —CH2CH(OH)(G) with G being hydrogen, methyl or phenyl;n is 1, 2, 3 or 4;n* is 1, 2 or 3;X is an organic radical of a valency equal to n; andX* is a triazinic radical with a valency equal to n*;with the proviso that when n is 1, R is methyl, ethyl, propyl, C1–C18hydroxyalkyl, C2C18alkenyl, C5–C12cycloalkyl or C1–C18alkanoyl.The compounds described above are useful for stabilizing an organic material against degradation induced by light, heat or oxidation.
