Patent

CA 2249570

The present invention provides compounds having the formula (1) or (1A) 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-C13aralkyl, -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-C20alkoxy, C4- C12cycloalkoxy, C2-C20alkenoxy, C2-C20alkynoxy, C6-C12aryl, C6-C12aryloxy or C7-C13aralkyl), 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-C13aralkyl 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.

La présente invention concerne des composés de la formule (1) ou (1A). Dans cette formule, R est hydrogène, hydroxy, halogène, C¿1?-C¿20?-alkyle, C¿4?-C¿12?cycloalkyle, C¿2?-C¿20? alkényle, C¿2?-C¿20? alkynyle, C¿1?-C¿20?-alkoxy, C¿4?-C¿12?cycloalkoxy, C¿2?-C¿20?alkénoxy, C¿2?-C¿20?alkynoxy ou C¿7?-C¿13?aralkyle; R¿1? et R¿2? indépendamment sont hydrogène, C¿1?-C¿20?-alkyle, C¿4?-C¿12?cycloalkyle, C¿7?-C¿13?aralkyle, -C(=O)-R¿4? (où R¿4? est C¿1?-C¿20?alkyle, C¿2?-C¿20?-alkyle interrompu par 1 à 6 atomes d'oxygène, du C¿1?-C¿20?-alkyle hétéro-substitué, C¿4?-C¿12?cycloalkyle, C¿2?-C¿20?alkényle, C¿2?-C¿20?alkynyle C¿1?-C¿20?-alkoxy, C¿4?-C¿12? cycloalkoxy, C¿2?-C¿20?alkénoxy, C¿2?-C¿20?alkynoxy, C¿6?-C¿12? aryle, C¿6?-C¿12?aryloxy ou C¿7?-C¿13? aralkyle) ou -C(=O)-NH-R¿1? où R¿1? a sa signification précédente; et R¿3? est hydrogène, halogène, hydroxy, C¿1?-C¿20?alkyle, C¿4?-C¿12?cycloalkyle, C¿2?-C¿20? alkényle, C¿2?-C¿20? alkynyle, C¿1?-C¿20?-alkoxy, C¿4?-C¿12?cycloalkoxy, C¿2?-C¿20?alkénoxy, C¿2?-C¿20?alkynoxy, phényle, C¿7?-C¿13? aralkyle ou -N(R¿1?)(R¿2?) où R¿2? et R¿2? ont leur signification précédente ou R¿1? et R¿2? ensemble forment une chaîne à éléments C¿4?-C¿12?. Les nouveaux composés de triphényltriazine présentent des caractéristiques améliorées du spectre d'absorption et une résistance supérieure à l'exposition aux IV par rapport aux composés de triphényltriazine connus.
