Heterocyclic Carbon Compounds Containing A Hetero Ring Having Oxygen Or Sulfur
(AREA)
Abstract
Method of preparing protective means against light, characterized in that an organic compound is added containing the structure at least once ** (See formula) ** wherein A and B are isocyclic-aromatic radicals consisting of at most two condensed rings which may be further substituted by halogen and groups without a chromogenic character, which are linked by a carbon, oxygen or sulfur atom with the aromatic rings, to which end, further aromatic radicals, which are present, are bound directly or with the aid of bridging links saturated with A and B and in which A is linked at two neighboring carbon atoms with nitrogen atoms, to substrates or vehicles adequate.
