Modified 2-(2'-hydroxyphenyl)benzotriazole and 2-hydroxybenzophenone light stabilizers of formula (I) are new; in which n = 1, 2 or 3 and = the valency of A; if n = 1, A = a 6-20C (hetero)aromatic group, optionally with a condensed benzene ring on one or both sides of the aromatic group; if n = 2, A = a divalent 6-20C aromatic group, which may be bivalent per se or have 2 bridged groups; if n = 3, A = a trivalent 6-20 C aromatic group of formula (IIA-E); in all cases, group A may be mono- or poly-substituted by 1-4 C alkyl, trifluoromethyl (CF3), 1-4 C alkoxy, halogen, cyano (CN), carboxyl (COOH), nitro (NO2), amino (NH2), 1-4 C alkylamino, 1-4 C dialkylamino, acyl or acyloxy. B = -C(=O)-D-E; C' = hydrogen (H), CN or -C(=O)-D-E; D = an ether (-O-) or imino (-NH-) group; if D = -O-, E = 4-benzoyl-3-hydroxyphenyl group of formula (IIIA) or a 3-benzotriazol-2-yl-2-hydroxybenzyl group of formula (IIIB); if D = -NH-, E = a IIIB) group; R<1>, R<2>, R<3>, R<4> = substituent(s) selected from 1-18C alkyl, 1-18C alkoxy, halogen or CN. Also claimed are (i) the preparation of (I); and (ii) organic material stabilized with compound(s) (I).
