The present invention relates to novel compounds containing a tetramethylpiperidinyl unit. More specifically, it relates to novel compounds containing 2,2,6,6-tetramethyl-piperidinyl and 2-hydroxybenzophenone or (2-hydroxyphenyl) -2 benzotriazole units, which can be easily obtained from current raw materials. These compounds can be used as light stabilizers and thermal stabilizers in organic polymers. |
