Abstract: Composition (I) comprises in a support at least one UV filter system, which comprises: (i) at least one UV filter derived from dibenzoylmethane; (ii) at least one compound (a) capable of accepting the triplet excited energy level of the dibenzoylmethane derivative; and (iii) at least one siliceous-s-triazine compound or its tautomeric forms. Composition (I) comprises in a support at least one UV filter system, which comprises (i) at least one UV filter derived from dibenzoylmethane; (ii) at least one compound (a) capable of accepting the triplet excited energy level of the dibenzoylmethane derivative; and (iii) at least one siliceous-s-triazine compound of formula (D-Si(R) a1-O (3-a 1)/2) (XIV) or its tautomeric forms comprising silane units of formula (-A-(Si)(R) a1(O) 3-a1/2), or organosiloxane group of formula (R b1-Si(O) 4-b1/2). R : 1-30C alkyl optionally halogenated or unsaturated, 6-12C aryl, 1-10C alkoxy, OH or trimethylsilyloxy; a1 : 0-3; D : s-triazine group of formula (XV); X : O or NR 3>; R 3>H or 1-5C alkyl; R 1>1-30C alkyl (optionally unsaturated and containing silicon atom), 5-20C cycloalkyl (optionally substituted by 1-3 1-4C alkyl group), or group of formula (-(CH 2CHR 4>-O) m1R 5>) or (-CH 2CH(OH)CH 2-O-R 6>); R 4>H or CH 3, where the group (C=O)XR 1>may be ortho, meta or para to the amino group; R 5>H or 1-8C alkyl; R 6>H or 4-8C alkyl; m1 : 2-20; n1 : 0-2; either R 2>OH, 1-8C alkyl, or 1-8C alkoxy; or R 2>R 2>1 or 2C alkylidene dioxy group; A : methylene, -[CHSi(CH 3) 3]-, ethylene or group of formula (-Z-CHW 1>-CH 2-) (XVI), (-Z-CHCH 3-) (XVII), (-Z-CH=CH-) (XVIII), or (-Z-CH(=CH 2)-) (XIX); b1 : 1-3; Z : 1-10C alkylene diradical (optionally substituted by OH or O and optionally containing amino group); and W 1>H, OH or optionally saturated 1-8C alkyl. Independent claims are included for: (1) method for improving chemical stability against UV radiation of at least one dibenzoylmethane derivative comprising combining dibenzoylmethane derivative, at least one compound capable of accepting the triplet excited energy level of dibenzoylmethane derivative and at least one siliceous s-triazine (XIV); and (2) compounds comprising methyl 4-[[4-[(4-methoxycarbonylphenyl)amino]-6-[3-(methyl-bis(trimethylsilyloxy)silyl)propylamino]-1,3,5-triazin-2-yl]amino]benzoate, propyl 4-[[4-[3-(methyl-bis(trimethylsilyloxy)silyl)propylamino]-6-[(4-propoxycarbonylphenyl)amino]-1,3,5-triazin-2-yl]amino]benzoate, isopropyl 4-[[4-[(4-isopropoxycarbonylphenyl)amino]-6-[3-(methyl-bis(trimethylsilyloxy)silyl)propylamino]-1,3,5-triazin-2-yl]amino]benzoate, tert-butyl 4-[[4-[(4-methoxycarbonylphenyl)amino]-6-[3-(methyl-bis(trimethylsilyloxy)silyl)propylamino]-1,3,5-triazin-2-yl]amino]benzoate, tert-butyl 4-[[4-[(4-tert-butoxycarbonylphenyl)amino]-6-[3-(methyl-bis(trimethylsilyloxy)silyl)propylamino]-1,3,5-triazin-2-yl]amino]benzoate, pentyl 4-[[4-[3-(methyl-bis(trimethylsilyloxy)silyl)propylamino]-6-[(4-pentoxycarbonylphenyl)amino]-1,3,5-triazin-2-yl]amino]benzoate, 2,2-dimethylpropyl 4-[[4-[[4-(2, 2-dimethylpropoxycarbonyl)phenyl]amino]-6-[3-(methyl-bis(trimethylsilyloxy)silyl)propylamino]-1,3,5-triazin-2-yl]amino]benzoate, hexyl 4-[[4-[(4-hexoxycarbonylphenyl)amino]-6-[3-(methyl-bis(trimethylsilyloxy)silyl)propylamino]-1,3,5-triazin-2-yl]amino]benzoate, cyclohexyl 4-[[4-[[4-(cyclohexoxycarbonyl)phenyl]amino]-6-[3-(methyl-bis(trimethylsilyloxy)silyl)propylamino]-1,3,5-triazin-2-yl]amino]benzoate, cyclohexylmethyl 4-[[4-[[4-(cyclohexylmethoxycarbonyl)phenyl]amino]-6-[3-(methyl-bis(trimethylsilyloxy)silyl)propylamino]-1,3,5-triazin-2-yl]amino]benzoate, and (4-dodecylcyclohexyl) 4-[[4-[(4-dodecoxycarbonylphenyl)amino]-6-[3-(methyl-bis(trimethylsilyloxy)silyl)propylamino]-1,3,5-triazin-2-yl]amino]benzoate.
