<p>Composition (A) comprises in a support at least one UV filter system, which comprises (i) at least one dibenzoylmethane derivative; (ii) at least one caprolactam compound (I); and (iii) at least one siliceous-s-triazine compound (II) or its tautomeric forms, and comprising silane units, or organosiloxane groups. Composition (A) comprises in a support at least one UV filter system, which comprises (i) at least one dibenzoylmethane derivative; (ii) at least one caprolactam compound of formula (I); and (iii) at least one siliceous-s-triazine compound of formula (D-Si(R) a-O (3-a )/2) (II) or its tautomeric forms and comprising silane units of formula (-A-(Si)(R) a(O) 3-a/2), or organosiloxane group of formula (R b-Si(O) 4-b/2). n, m : 0 or 1; p : 0-13; R 0>alkyl containing t number of carbon atoms, preferably 1-20C; R : 1-30C alkyl optionally halogenated or unsaturated, 6-12C aryl, 1-10C alkoxy, OH or trimethylsilyloxy; a1, a : 0-3; D : s-triazine group of formula (III); 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-) (IV), (-Z-CHCH 3-) (V), (-Z-CH=CH-) (VI), or (-Z-CH(=CH 2)-) (VII); b : 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. Provided that: when p is 0 then m is 0; when p is 1 and n is 1, then m is 1; and when p is 1 and n is 0 then m is 0 and R 1>is 2-20C alkyl, and the sum of p and t is 3-20. An independent claim is included for method for improving chemical stability, against UV radiation, of at least one dibenzoylmethane derivative comprising combining dibenzoylmethane derivative, at least one caprolactam derivative (I), and at least one siliceous-s-triazine compound (II).
