    • Prevention of the uptake of migrating dyes in wash liquors containing a peroxide-containing washing agent by adding 0.5-150 mg/l of a non-symmetrical Mn complex (I) is claimed, as are also: (i) some the compounds (I) which are novel; (ii) (ii) novel bisphenol ligands (II) for preparation of (I); (iii) preparation of (II); (iv) 2 specific compounds of type (I); and (v) wash liquors containing (I). The Mn complexes (I) used in the wash liquors: n = 0, 1, 2 or 3; m = 1, 2 or 3; A = an anion; Y = (a) an alkylene group of formula -(C(R5)2)r; (b) -CX:CX-; (c) -(CH2)q-NR4-CH2)q-; or (d) 1,2-cyclohexylene or -phenylene, each optionally substituted by R9 as per formula (III) or (IV); r = 1-8; R4 and R5 = H or 1-4C alkyl; X = cyano, 1-8C alkyl or di(1-8C alky)amino; q = 1, 2, 3 or 4; R9 = SO3H, CH2OH or CH2NH2; R and R1 = cyano, halogen, OR5, COOR5, nitro, 1-8C alkyl (optionally partially or fully fluorinated), NHR6, NR6R7, 1-8C alkyl-R8, or N R4R6R7, with the proviso that R and R1 are not the same when n = m; R6 and R7 = 1-12C alkyl or together and with the bonded N atom form a 5-, 6- or 7-membered ring optionally containing further heteroatoms; R8 = OR5, COOR5, NR6R7 or NH2; R2 and R3 = H, 1-4C alkyl, aryl (optionally substituted by cyano, halogen, OR5 or COOR5), nitro, 1-8C alkyl, NHR6, 1-8C alkyl-R8 or N R4R6R7 The Independent claims cover (i) novel compounds (IA) as per formula (I) but in which R2 and R3 are both H and the case in which one of these is H and the other is phenyl is excluded; (ii) novel ligands of formula (II); (iii) preparation of (II); (iv) the 2 specific compounds of type (I) as shown by formulae (IB) and (IC) under SPECIFIC COMPOUNDS below; and (v) wash liquors comprising by wt. (a) 5-90% anionic and/or nonionic surfactants; 5-70% builder; 0.1-30% peroxide; and 0.005-2% (I); or (b) 5-70% anionic and/or nonionic surfactants; 5-40% builder; 1-12% peroxide; and 0.1-0.5% (I).
