Abstract
The invention relates to anthraquinone compounds of the formula (1) ##STR1## wherein the substituents are as defined in the specification. The compounds of formula (1) are water-soluble, fiber-reactive dyes useful for dyeing and printing materials, in particular fiber materials containing hydroxy, mecapto, amino and/or carboxamide groups.
Claims8
An anthraquinone compound of the formula ( 1) ##STR15## in which R.sup.1 is hydrogen, C.sub.1 -C.sub.6 -alkyl-carbonyl, C.sub.6 -aryl-carbonyl, C.sub.1 -C.sub.4 -alkylphenylcarbonyl, C.sub.1 -C.sub.6 -alkyl, C.sub.3 -C.sub.6 -cycloaklyl or phenyl, where C.sub.1 -C.sub.6 -alkyl, C.sub.3 -C.sub.6 -cycloalkyl and phenyl are optionally substituted by one or more radicals from the group consisting of hydroxyl, sulfo, carboxyl, C.sub.1 -C.sub.4 -alkyl, C.sub.1 -C.sub.4 -alkoxy, halogen, cyano, amino and nitro;
- R.sup.2 is sulfo or carboxyl;
- m is a number from 0 to 2;
- R.sup.3 is sulfo, carboxyl or halogen;
- n is the number 0 or 1;
- R.sup.4 is sulfo, carboxyl, C.sub.1 -C.sub.4 -alkyl or C.sub.1 -C.sub.4 -alkoxy;
- p is a number from 0 to 2;
- W is a C.sub.1 -C.sub.6 -alkylene group;
- X is vinyl or --CH.sub.2 CH.sub.2 --L, in which L is a group which can be split off under alkaline conditions and is selected from the group consisting of chlorine, bromine, --OSO.sub.3 M, --SSO.sub.3 M or --OP.sub.3 M.sub.2, in which M is hydrogen or an alkali metal;
- Y is a bridge member of the formula --O-- or --NH-- with the proviso that W is a C.sub.3 -C.sub.6 -alkylene group if
- X is vinyl and at the same time Y is --NH--.
