Abstract:
A process for washing and cleaning as well as for preventing the reabsorption of migrating dyes in a washing liquor, which process comprises adding to a washing liquor which comprises a peroxide-containing washing agent, 0.5 to 150 mg per liter of the washing liquor of a mixture consisting of 2 to 85% by weight of a manganese complex which is a compound of formula whereinA is an anion; n is 0, 1, 2 or 3, m is 0, 1, 2 or 3, R4 is hydrogen or linear or branched C1-C4alkyl, R8 is hydrogen or linear or branched C1-C4alkyl, Y is a linear or branched alkylene radical of formula â€”[C(R4)2]râ€”, wherein r is an integer from 1 to 8 and the R4 groups have each independently of one another the meanings cited above; â€”CX&boxH;CXâ€”, wherein X is cyano, linear or branched C1-C8alkyl or di(linear or branched C1-C8alkyl)amino, â€”(CH2)qâ€”NR4â€”(CH2)qâ€”, wherein R4 has the meaning cited above, and q is 1, 2, 3 or 4; or a 1,2-cyclohexylene radical of formula: â€ƒor a 1,2-aryl radical of formula whereinR9 is hydrogen, SO3H, CH2OH or CH2NH2, R and R1 are each independently of the other cyano, halogen, OR4 or COOR4, wherein R4 has the meaning cited above, nitro, linear or branched C1-C8alkyl, linear or branched partially fluorinated or perfluorinated C1-C8alkyl, NR5R6, wherein R5 and R6 are identical or different and are each hydrogen or linear or branched C1-C12alkyl, or linear or branched C1-C8alkyl-R7, wherein R7 is NH2, OR4, COOR4 or NR5R6, which have the meanings cited above, or â€”CH2â€”NâŠ•R4R6R7, or â€”NâŠ•R4R5R6, wherein R4, R5 and R5 have the meanings cited above, R2 and R3 are each independently of the other hydrogen, linear or branched C1-C4alkyl or unsubstituted aryl, or aryl which is substituted by cyano, halogen, OR4or COOR4, wherein R4 is hydrogen or linear or branched C1-C4alkyl, by nitro, linear or branched C1-C8alkyl, NHR5 or NR5R6; wherein R5 and R6 are identical or different and are each hydrogen or linear or branched C1-C12alkyl, or by linear or branched C1-C8alkyl-R7, wherein R7 is NH2, OR4, COOR4 or NR5R6, which have the meanings cited above, or by â€”NâŠ•R4R5B6, wherein R4, R5 and R6 have the meanings cited above, and 98 to 15% by weight of an organic ligand of the formula wherein R, R1, R2, R3, R8, Y, n and m are as defined above, the percentages being based on the entire weight of the mixture.
