wherein
R 1 and R 2 each independently from each other are a residue of an organic dye;
Y 1 and Y 2 each independently from each other are unsubstituted or substituted, straight-chain or branched, interrupted or uninterrupted -C 1 -C 10 alkylene-; -C 5 -C 10 cycloalkylene-; C 5 -C 10 arylene; or-C 5 -C 10 arylene-(C 1 -C 10 alkylene)-;
Z 1 and Z 2 independently from each other are -C(O)-; -C 2 -C 12 alkenylene-; -(CH 2 CH 2 -O) 1-5 -; -C 1 -C 10 alkylene(C 5 -C 10 arylene)-; -C 5 -C 10 arylene-; -C 5 -C 10 cycloalkylene-; -C(O)O-;
-CON(R 4 )-; -(R 5 )NC(O)-; -O-; -S-; -S(O)-; or-S(O) 2 -;
R 3 , R 4 and R 5 are each independently from each other hydrogen; or unsubstituted or substituted, straight-chain or branched, monocyclic or polycyclic, interrupted or uninterrupted C 1 -C 14 alkyl; C 2 -C 14 alkenyl; C 6 -C 10 aryl; C 6 -C 10 aryl-C 1 -C 10 alkyl; or C 5 -C 10 alkyl(C 5 -C 10 aryl);
r, q and n independently from each other are 0 or 1,
if n is 0,
Z 3 is hydrogen; and
if n is 1,
Z 3 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. |
