    摘要: Mixtures of a polymer which contains polyalkylpiperidines chemically bonded in any form and a metal compound MeL.sub.w, in which Me is a divalent or trivalent metal ion or a divalent oxo-metal ion or a divalent dialkyl-tin ion, L is the monovalent anion of a carboxylic acid, of a phosphinic acid or of a phosphonic acid monoester or of an enol and w is 2 or 3, are effective light stabilizers for plastics. The piperidine-containing polymers can be, for example, polyesters, polyamides, polyamines, polyaminotriazines or poly(meth)-acrylates. Examples of metal compounds MeL.sub.w are nickel oenanthate or nickel acetylacetonate. Plastics to be stabilized are in particular the polyolefins.

    摘要: Compounds of the formula I ##STR1## in which X is a group ##STR2## and R.sup.1, R.sup.2, R.sup.3, R.sup.4 and R.sup.5 are monovalent organic radicals, at least one of which contains a sterically hindered phenol group and at least one of which contains a polyalkylpiperidine group, are outstanding light stabilizers for color-photographic recording materials. They also have a stabilizing action on the photo dyes and their precursors when stored in the dark.
