Suitable stabilizers for organic material are a mixture comprising  

Stabilizer mixture

A description is given of a stabilizer composition comprising

Stabilizer composition

4-formylamino-N-methylpiperidine derivatives, the use thereof as stabilizers and organic material stabilized therewith

Described is a stabilizer composition comprising a 3-arylacrylic ester, a polymeric compound having a molecular weight of at least 2000 which carries, on a polymeric framework, side groups having secondary amine functions, all substituents positioned to the amine nitrogen being other than hydrogen, a chroman derivative, and an organic phosphite and/or phosphonite. The stabilizer composition is particularly suitable for stabilizing thermoplastic polyurethane against light, oxygen and heat.

A polymer is obtained by removing the medium from a polymer dispersion or polymer solution containing at least one polymeric phase and at least one stabilizer suitable to protect against the damaging effect of light, heat and/or oxidation.
