ABSTRACT:
RELATED APPLICATIONS
This application is a Rule 1.137 application of PCT application No. PCT/EP01/11542 filed Oct. 6, 2001 which claims benefit to German application no. 100 51 018.3 filed Oct. 14, 2000.
DESCRIPTION
The present invention relates to novel reactive dyes, processes for their preparation and their use for dyeing or printing textile fiber materials.
Reactive dyes for dyeing or printing hydroxyl- and/or carboxamido-containing materials these days must combine good general fastness properties with good washoff of the unfixed portions. Given the dyes available at present, there is accordingly room for improvement.
It is an object of the present invention to provide novel, improved reactive dyes for the dyeing and printing of hydroxyl- and/or carboxamido-containing materials, especially fiber materials, that combine good general fastness properties, especially a high lightfastness, with good washoff of the unfixed portions.
This object is surprisingly achieved by the hereinbelow described dyes according to the invention.
The present invention accordingly provides reactive copper, cobalt or chromium complex compounds of the general formula (1)

B is a direct bond or a bridge member;
X is a fiber-reactive structural element;

R

is hydrogen, hydroxyl, carboxyl or sulfo;
R
4
is hydrogen or sulfo;
R
5
is hydrogen, alkyl of 1 to 4 carbon atoms which can be substituted by halogen, hydroxyl, cyano, alkoxy of 1 to 4 carbon atoms, alkoxycarbonyl of 2 to 5 carbon atoms, carboxyl, sulfo or sulfato;
h, k, l, m are independently 0 or 1;
Me is copper, cobalt or chromium, preferably copper and cobalt and particularly preferably copper;
M is hydrogen or an alkali metal, such as sodium, potassium or lithium, or the mole equivalent of an alkaline earth metal, such as calcium, and preferably is hydrogen or an alkali metal.
Suitable fiber-reactive radicals X, i.e., those which react with the OH or NH groups of the fiber under dyeing conditions to form covalent bonds, are for example —SO

or pyridinium, which may be substituted, for example by alkyl of 1-4 carbon atoms, carboxyl, sulfo, cyano or carbamoyl, where M is as defined above, or are fiber-reactive radicals X, especially those which contain at least one reactive substituent attached to a 5- or 6-membered aromatic heterocyclic ring, for example to a monoazine, diazine or triazine ring, especially a pyridine, pyrimidine, pyridazine, pyrazine, thiazine, oxazine or asymmetrical or symmetrical triazine ring, or to such a ring system that comprises one or more fused-on aromatic carbocyclic rings, for example a quinoline, phthalazine, cinnoline, quinazoline, quinoxaline, acridine, phenazine or phenanthridine ring system.
Fiber-reactive radicals selected from the pyrimidines or triazines are particularly suitable.
Examples of reactive substituents on the heterocycle include halogen (Cl, Br or F), ammonium including hydrazinium, pyridinium, picolinium, carboxypyridinium, sulfonium, sulfonyl, azido(N3), thiocyanato, sulfinic acid and sulfonic acid.
