Abstract
Fibre-reactive asymmetrical triphenodioxazine compounds conform to the formula I ##STR1## where the individual symbols are as defined in the description, and mixtures thereof and are present in the form of a free acid or as salt. They are used as reactive dyes for dyeing or printing hydroxyl-containing or nitrogenuos organic substrates, such as leather or fiber material consisting of or comprising natural or synthetic polyamides or natural or regenerated cellulose; the most preferred substrate is textile material consisting of or comprising cotton.
Claims1
A dyestuff composition comprising (A) a compound according to formula (I) ##STR56## its salts or mixtures thereof, wherein
- T.sub.1 and T.sub.2 are independently of each other selected from hydrogen, chlorine, bromine, C.sub.1-4 alkyl, C.sub.1-4 alkoxy and phenoxy,
- X is selected from -NR.sub.2 R.sub.3 and -NR.sub.1 -Z,
- each R.sub.1 is independently of the other selected from hydrogen, C.sub.1-4 alkyl, and substituted C.sub.1-4 alkyl,
- R.sub.2 and R.sub.3 are independently of each other selected from hydrogen, C.sub.1-4 alkyl, substituted C.sub.1-4 alkyl and cyclohexyl, or
- -NR.sub.2 R.sub.3 is a group selected from a 5- or 6-membered heterocyclic ring, a 5- or 6-membered heterocyclic ring having one or two additional hetero atoms selected from oxygen, nitrogen and sulphur atoms and a 5- or 6-membered heterocyclic ring having one or two additional hetero atoms selected from oxygen, nitrogen and sulphur atoms which is further substituted with a group selected from amino, sulpho, hydroxyl, alkyl, alkoxy, fluoro, chloro and bromo,
- R.sub.4 is selected from hydrogen, halogen, C.sub.1-4 alkyl, C.sub.1-4 alkoxy and carboxyl,
- W is selected from an aliphatic, araliphatic, aromatic- and cycloaliphatic diamino bridge member,
- Y is selected from fluorine, chlorine and C.sub.1-4 alkoxy,
- each Z is independently of the other a heterocyclic fibre-reactive radical containing at least one labile fluorine or chlorine atom, and
- each m is independently of the other 1 or 2;
- (B) a compound according to the formula (V) ##STR57## and (C) a compound according to the formula (VI) ##STR58## their salts or mixtures thereof.
