Abstract (en)
[origin: WO2007107313A2] The invention relates to agents which contain a combination of special sulphinic acid derivatives of formula (I) in a carrier, wherein M represents a hydrogen atom or an equivalent of a mono or polyvalent cation, R is derived from a peptide or represents a group according to one of the formulae (II) to (VI), (for the meanings of the remaining substitutients see claim 1) and at least one compound comprising at least one quaternary nitrogen atom. Said agents enable a durable decolouration of the dyed substrates to take place without darkening the decoloured substrate. The substrate structure is not damaged during the decolouration process.
