| abstract |
B = CH=CH 2 oder CH 2 CH 2 Z, worin Z eine abspaltbare Gruppe darstellt R = H oder gegebenenfalls substituiertes C 1 -C 4 -Alkyl R 1 = H oder Substituent K = Rest einer Kupplungskomponente der Hydroxynaphthalin-, Pyrazol- oder Pyridon-Reihe W = direkte Bindung oder zweiwertiges Brückenglied X = Rest einer Reaktivkomponente der Pyrimidinreihe, der mindestens ein unter Färbebedingungen abspaltbares Fluoratom enthält n = 0 oder 1. The present invention relates to the copper, cobalt or chromium complexes of disazo dyes of the formula wherein B = CH = CH 2 or CH 2 CH 2 Z, wherein Z represents a removable group R = H or optionally substituted C 1 -C 4 alkyl R 1 = H or substituent K = rest of a coupling component of the hydroxynaphthalene, pyrazole or pyridone series W = direct bond or divalent bridge link X = residue of a reactive component of the pyrimidine series which contains at least one fluorine atom which can be split off under dyeing conditions n = 0 or 1. n n n They are suitable for dyeing and printing hydroxyl groups or materials containing amide groups. |
