Abstract
Tris-aryl-s-triazines of formula V ##STR1## which contain from one one to three resorcinol derived moieties with at least one of said moieties substituted in the 5-position with a group such as, for example, alkyl or phenylalkyl have UV spectra which are red-shifted to the near UV range and provide excellent stabilization to polymeric substrates against the deleterious effects of actinic light.
