The invention relates to a stabilizing mixture containing A) a certain sterically hindered amine which is, for example, at least one compound of formula (I) wherein the radicals R1 are each independently hydrogen, a C1-C8 alkyl group, -O., -CH2CN, C3-C6 alkenyl, C7-C9 phenylalkyl optionally substituted on the phenyl radical by one or more C1-C4 alkyl groups, or a C1-C8 acyl group; B) an organic oxide, hydroxide or salt of magnesium or zinc, or a hydrotalcite; and C) a UV light absorbent and / or a pigment. This stabilizing mixture is useful for stabilizing a polyolefin against degradation caused by light. Field of application: Stabilizers for plastics. |
