Abstract
Monoazo compounds which possess fiber-reactive groups and have useful dye properties and are capable of dyeing hydroxyl- and/or carboxamido-containing materials, in particular fiber materials, such as cellulose fibers and natural and synthetic polyamide, such as wool, in strong, fast shades. They conform to the formula ##STR1## wherein D, K and Me are as defined in the specification.
Claims10
A monoazo compound conforming to the formula (b 1) ##STR13## where Me is hydrogen or an alkali metal;
- K is a radical of the formula (2) ##STR14## where Me has one of the abovementioned meanings and
- n is zero or 1 (if zero, this group being hydrogen);
- D is a group of the formula (3a), 3b) or (3c) ##STR15## where Me has one of the abovementioned meanings,
- R.sup.1 is hydrogen, alkyl of from 1 to 4 carbon atoms, which may be sulfo-, carboxyl- or sulfato-substituted, alkoxy of from 1 to 4 carbon atoms, which may be sulfo-, carboxyl-, or sulfato-substituted, chlorine, bromine, hydroxyl, cyano, carboxyl or sulfo,
- R.sup.2 is hydrogen, alkyl of from 1 to 4 carbon atoms or alkoxy of from 1 to 4 carbon atoms,
- Y is vinyl or ethyl which contains in the .beta.-position a substituent which is eliminable by alkali to form a vinyl group, and
- m is zero, 1 to 2 (if zero, this group being hydrogen).
