<p>Organo-siloxane and organo-silane salicylic acid derivatives of formulae (I), (II) and (III) are new. Ra-Rg = 1-10C alkyl, 2-10C alkenyl (these may be unsaturated or saturated (sic)), phenyl or 3,3,3-trifluoropropyl,≥80% of Ra-Rg being methyl; A = a group of formula (IV) directly attached to a silicon atom; R1 = OH, 1-4C alkoxy (saturated or unsaturated), or O(C=O)R4; R2 = OH, 1-8C alkyl, 2-8C alkenyl or 1-8C alkoxyl; or two adjacent groups R2 may form 1-2C alkanedioxy; R3 = H, cation, 1-6C alkyl, 2-6C alkenyl, or benzyl (optionally substituted by 1-6C alkyl, 2-6C alkenyl, OH, amino, 1-6C alkoxy, 2-6C alkenyloxy, halo, carboxylic acid, 1-6C alkyl carboxylate or 2-6C alkenyl carboxylate); such that when R1 is other than OH, then R3 is H or a cation; R4 = 1-8C alkyl or alkenyl; m = 0-2; p = 0 or 1; X = O, NH, C=O, NH(C=O)NH, NH(C=O), or (C=O)NH; n = 0 or 1; Z = 1-6C alkanediyl, optionally unsaturated and optionally substituted by OH, or optionally unsaturated 2-8C alkoxy; Y = H, OH, or optionally unsaturated 2-8C alkoxy; B1, B2 = as Ra-Rg or A; R1', R2', R3' = 1-8C alkyl, 2-8C alkenyl, phenyl, or 1-4C alkoxy; r = 0-50; s = 0-20, such that when s = 0, then≥1 of B1 and B2 is A; u = 1-6; and t = 0-10, such that t+u≥3.</p> |
