    摘要： The present invention provides a process for inhibiting the re-absorption of migrating dyes in the wash liquor, comprising introducing into a wash liquor containing a peroxide-containing detergent, from 0.5 to 150, preferably from 1.5 to 75, especially from 7.5 to 40 mg, per liter of wash liquor, of one or more compounds having the formula: in which n is 1, 2 or 3; A is an anion; Y is —(CH2)m in which m is an integer ranging from 1 to 8; —(CH2)p—CH(R1)— in which p is an integer ranging from 1 to 7 and R1 is linear or branched C1-C4-alkyl, preferably methyl; —CX═CX— in which X is cyano, linear or branched C1-C8-alkyl or di(linear or branched C1-C8-alkyl)-amino; —(CH2)q—NR1—(CH2)q— in which R1 has its previous significance and q is 1, 2, 3 or 4; or a 1,2-cyclohexylene residue having the formula: R is cyano; halogen; hydroxy; OR1 in which R1 has its previous significance; CO2R2 in which R2 is hydrogen or linear or branched C1-C4-alkyl; nitro; linear or branched C1-C8-alkyl; di-(C4-C12alkyl)amino; NR3R4 in which R3 and R4 are the same or different and each is linear or branched C1-C12-alkyl; or —N⊕R1R3R4 in which R1, R3 and R4 have their previous significance.
