    摘要： The invention is related to modified polyurethanes which have a permanent, wash-fast, acidresistant, dry cleaning-resistant and solvent-resistant stabilization based on 2,2,6,6-tetraalkyl-piperidine light protective agents. These stabilizers are an integral constituent of the polyurethanes, that is to say they take part in the polyurethane synthesis by the reaction of an H-active reactive group (for example NH.sub.2, NH-alkyl, CO--NH--NH.sub.2, NH--CO--NH--NH.sub.2, OH or some other H-active group) of the 2,2,6,6-tetraalkyl-piperidine derivatives with isocyanate groups of polyisocyanates or isocyanate prepolymers.
