LIGHT-STABILIZED COMPOSITION

摘要

The present invention relates to a light-stabilized composition comprising at least one polymer and 0.01 to 25 % by weight, based on the total weight of the composition, of a light-stabilizing component comprising at least one heptaazaphenalene compound of general formula (I), wherein the radicals R₁, R₂ and R₃ are defined in the description, optionally in combination with at least one further light stabilizer (Z), articles, moulds, sheets, foils or films produced of such light-stabilized composition, the use of at least one heptaazaphenalene compound of general formula (I) as a light stabilizer for polymers as well as to a light stabilizer combination comprising at least one of said heptaazaphenalene and at least one further light-stabilizer (Z).
