    • The present invention provides compounds having the formula: in which R is hydrogen, hydroxy, halogen, C1-C20-alkyl, C4-C12cycloalkyl, C2-C20alkenyl, C2-C20alkynyl, C1-C20-alkoxy, C4-C12cycloalkoxy, C2-C20alkenoxy, C2-C20alkynoxy or C7-C13aralkyl; R1 and R2, independently, are hydrogen, C1-C20alkyl, C4-C12cycloalkyl, C7-C13 aralkyl, —C(═O)—R4 (in which R4 is C1-C20alkyl, C2-C20alkyl interrupted by 1 to 6 oxygen atoms, hetero-substituted C1-C20alkyl, C4-C12cycloalkyl, C2-C20alkenyl, C2-C20alkynyl, C1-C20-alkoxy, C4-C12cycloalkoxy, C2-C20alkenoxy, C2-C20alkynoxy, C6-C12 aryl, C6-C12 aryloxy or C7-C13 aralkyl), or —C(═O)—NH—R1 in which R1 has its previous significance; and R3 is hydrogen, halogen, hydroxy, C1-C20alkyl, C4-C12cycloalkyl, C2-C20alkenyl, C2-C20alkynyl, C1-C20-alkoxy, C4-C12cycloalkoxy, C2-C20alkenoxy, C2-C20alkynoxy, phenyl, C7-C13 aralkyl or —N(R1)(R2) in which R1 and R2 have their previous significance, or R1 and R2 together form a C4-C12 membered ring. The new triphenyltriazine compounds have improved absorption spectrum characteristics and superior resistance to exposure to UV light, relative to known triphenyltriazine compounds.
