CA 2215261

There are described compounds of formula A (see fig. I) (A) wherein r, and r2 are each independently of the other 0 or 1; Y1 to Y9 are each independently of the others -H, -OH, C1-C20alkyl, C4-C12cycloalkyl, C2-C20- alkenyl, C1-C20alkoxy, C4-C12cycloalkoxy, C2-C20alkenyloxy, C7-C20aralkyl, halogen, -C~N,C1-C5haloalkyl,-SO2R',-SO3H, -SO3M, wherein M is an alkali metal, -COOR', -CONHR',-CONR'R",-OCOOR',-OCOR',-OCONHR', (meth)acrylamino, (meth)- acryloxy, C6-C12aryl; C6-C12aryl substituted by C1-C12alkyl, C1-C12alkoxy, CN and/or by halogen; C3-C12heteroaryl; C3-C12heteroaryl substituted by C1-C12alkyl, C1-C12alkoxy, CN and/or by halogen; or Q of formula 1, and at least one substituent Y1 to Y9 must be .OMEGA. (see fig. II), (I) wherein q is 0 or 1, R is a cyclic radical and R1 and T are as defined in claim 1. The novel compounds are suitable, especially in combination with hindered amines, for the stabilisation of organic material against the damaging action of light, oxygen and heat.

On décrit des composés de formule A (voir fig. I) (A) où r et r2 sont, indépendamment l'un de l'autre, 0 ou 1; Y1 à Y9 sont indépendamment les uns des autres -H, -OH, un alkyle en C1-C20, un cycloalkyle en C4-C12, un alkényle en C2-C20, un alcoxy en C1-C20, un cycloalcoxy en C4-C12, un alkényloxy en C2-C20, un aralkyle en C7-C20, un halogène, -C~N, un haloalkyle en C1-C5, -SO2R',-SO3H, -SO3M, où M est un métal alcalin, -COOR', -CONHR', -CONR'R",-OCOOR', -OCOR', -OCONHR', un (méth)acrylamino, un (méth)acryloxy, un aryle en C6-C12; un aryle en C6-C12 substitué par un alkyle en C1-C12, un alcoxy en C1-C12, CN et/ou un halogène; un hétéroaryle en C3-C12; un hétéroaryle en C3-C12 substitué par un alkyle en C1-C12, un alcoxy en C1-C12, CN et/ou un halogène; ou Q de formule 1, et au moins un substituant Y1 à Y9 doit être OMEGA (voir fig. II), (I) où q est 0 ou 1, R est un radical cyclique et R1 et T sont tels que définis dans la revendication 1. Les nouveaux composés conviennent, surtout en combinaison avec des amines encombrées, pour la stabilisation des matières organiques contre les dommages causés par la lumière, l'oxygène et la chaleur.
