摘要

Photostabilization of at least a dibenzoylmethane derivative against UV radiation, comprises contacting an s-triazine silane compound (I) or its tautomeric form with the dibenzoylmethane derivative. Photostabilization of at least a dibenzoylmethane derivative against UV radiation, comprises contacting an s-triazine silane compound (I) of formula ((D)-(Si)(R) a-O (3-a)/2) or its tautomeric form with the dibenzoylmethane derivative. R : optionally halogenated or unsaturated 1-30C alkyl, 6-12C aryl, 1-10C alkoxy or trimethylsilyloxy group; a : 0-3; D : s-triazine compound of formula (II); X : O or NR 3; R 3H or 1-5C alkyl; R 11-20C alkyl (optionally unsaturated and comprising silicon), 5-20C cycloalkyl (optionally substituted by 1-3 radicals of 1-4C alkyl), (CH 2CHR 4-O) m-R 5 or CH 2-CH (OH)-CH 2-O-R 6; R 4H or CH 3; R 5H or 1-8C alkyl; R 6H or 4-8C alkyl; R 2OH, 1-8C alkyl or 1-8C alkoxy; A : divalent radical of methylene, [CH(Si(CH 3)) 3], ethylene or a group (III) of formula ((Z)-CH(W 1)-CH 2), group (IV) of formula ((Z)-CH=CH) or group (V) of formula ((Z)-C(=CH 2)); Z : 1-10C alkylene diradical (optionally substituted by a hydroxyl radical or O and optionally comprises amino group); W 1H, OH or 1-8C alkyl; m : 2-20; and n : 0-2. Provided that: two adjacent R 2 groups of the same aromatic nucleus together can form a 1-2C alkylidene dioxy group; and (C=O)XR 1 can be in ortho, meta or para position with respect to the amino group. Independent claims are included for: (1) a composition comprising a filter system, containing at least a UV filter derived from dibenzoylmethane and (I) in a support; (2) s-triazine silane compound (I); (3) 2,4-bis[4'-diylamino benzamide (1,1,3,3-tetramethylbutyl)]-6-{[1,3,3,3-tetramethyl-1-[(trimethylsilyl)oxy]disiloxanyl]propyl-3-ylamino}-s-triazine; (4) a triazine silica compound (Ic) of formula (D)-Si(R 8)-3; (5) 2,4-bis(4'-diylamino methyltrimethylsilyl benzoate)-6-{[1,3,3,3-tetramethyl-1-[(trimethylsilyl)oxy]disiloxanyl]propyl-3-ylamino}-s-triazine; (6) 2,4-bis(2'-hydroxy-4'-diylamino ethyl-2-hexyl benzoate)-6-{[1,3,3,3-tetramethyl-1-[(trimethylsilyl)oxy]disiloxanyl]propyl-3-ylamino}-s-triazine; and (7) s-triazine compound of formula (Ig) (where r is 1 or 8).
