Compounds containing both a UV-absorbing moiety and a 1-hydrocarbyloxy hindered amine moiety are effective stabilizers for protecting polymer compositons against the deleterious effects of actinic light. The UV-absorbing moieties include the substituted 2H-benzotriazoles, s-triazines, acrylates, benzophenones, oxanilides and oxamides. |
