Abstract
The present invention provides compounds having the formula: in which R is hydrogen, hydroxy, halogen, C-C-alkyl, C-Ccycloalkyl, C-Calkenyl, C-Calkynyl, C-C-alkoxy, C-Ccycloalkoxy, C-Calkenoxy, C-Calkynoxy or C-Caralkyl; Rand R, independently, are hydrogen, C-Calkyl, C-Ccycloalkyl, C-Caralkyl, —C(═O)—R(in which Ris C-Calkyl, C-Calkyl interrupted by 1 to 6 oxygen atoms, hetero-substituted C-Calkyl, C-Ccycloalkyl, C-Calkenyl, C-Calkynyl, C-C-alkoxy, C-Ccycloalkoxy, C-Calkenoxy, C-Calkynoxy, C-Caryl, C-Caryloxy or C-Caralkyl), or —C(═O)—NH—Rin which Rhas its previous significance; and Ris hydrogen, halogen, hydroxy, C-Calkyl, C-Ccycloalkyl, C-Calkenyl, C-Calkynyl, C-C-alkoxy, C-Ccycloalkoxy, C-Calkenoxy, C-Calkynoxy, phenyl, C-Caralkyl or —N(R)(R) in which Rand Rhave their previous significance, or Rand Rtogether form a C-Cmembered ring. The new triphenyltriazine compounds have improved absorption spectrum characteristics and superior resistance to exposure to UV light, relative to known triphenyltriazine compounds.
