SULFIDE DYES

Formula (I) wherein R1 and R2 each independently from each other are a residue of an organic dye; Y1 and Y2 each independently from each other are unsubstituted or substituted, straightchain or branched, interrupted or uninterrupted -C1-C10alkylene-; -C5-C10cycloalkylene-; C5-C10arylene; or-C5-C10arylene-(C1-C10alkylene)-; Z1 and Z2 independently from each other are Formula (II) are each independently from each other hydrogen; or unsubstituted or substituted, straight-chain or branched, monocyclic or polycyclic, interrupted or uninterrupted C1-C14alkyl; C2-C14alkenyl; C6-C10aryl; C6-C10aryl-C1-C10alkyl; or C5-C10alkyl(C5-C10aryl); r, q and n independently from each other are 0 or 1, if n is 0, Z3 is hydrogen; and if n is 1, Z3 is -S-; with the proviso that the method does not comprise treating the fiber with an enzyme of the type of a protein disulfidisomerase (EC 5.3.4.1). Further, the present invention relates to novel disulfid compounds, compositions thereof, especially comprising other dyes, and to processes for their preparation.
