ABSTRACT:
A process is described 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 (1), (2), (3), (4), (5), (6), (7), (8), (9), (10), (11), (12), (13) or (14) as defined in the specification. The compounds of formula (1), (2), (3), (4), (5), (6), (8), (9) (10), (11), (12), (13) or (14) are new compounds. The compounds used do not exhaust at all on to cotton, polyamide or polyester fibers, so that the compounds cannot lead to fiber discoloration problems.
