A stabilizer composition is described which comprises a 3-arylacrylic acid ester, a polymeric compound having a molecular weight of at least 2000 and which has side groups with secondary amine functions on a polymeric skeleton, in which all substituents in the alpha position to the amine nitrogen atom are different from hydrogen, a chroman derivative and a contains organic phosphite and / or phosphonite. The stabilizer composition is particularly suitable for stabilizing thermoplastic polyurethane against light, oxygen and heat. |
