Abstract
Dyes of the general formula (1): where M is hydrogen, alkali, ammonium or the equivalent of an alkaline earth metal ion, X is halogen, alkoxy or an N-containing heterocycle, Q is a grouping of the formula (e) where Y is vinyl or an alkali-eliminable grouping and W is alkyl which may be interrupted by an O or an NR group and the radicals R1 and R2 represent alkyl, alkoxy, alkylcarbonylamino, arylcarbonylamino, and also the radicals R3 and R4 are alkyl or hydrogen, their preparation and their use for dyeing and printing hydroxyl- and/or carboxamido-containing material, preferably fiber material.
Claims14
A dye of the general formula (1):
- wherein
- M is hydrogen, alkali, ammonium or the equivalent of an alkaline earth metal ion,
- X is halogen, C1-C4 alkoxy, amino, a 5- or 6-membered nitrogen heterocycle of the formula (a), (b), (c) or (d)
- wherein when X is a group of the formula (a)
- A- is fluoride, chloride or the equivalent of a sulfate ion and
- n is 1 or 2;
- or X is unsubstituted or sulfo- or hydroxyl-mono- or -disubstituted anilino, an alkylamino or N,N-dialkylamino with C1-C4-alkyl,
- R1 is C1-C6 alkyl, C1-C6-alkoxy, chlorine, C1-C4-alkylcarbonylamino or arylcarbonylamino;
- R2 has any meaning of R1 or else R1 and R2 combine to form a ring of the formula (f) or (g):
- R3 is C1-C6-alkyl or hydrogen;
- Q is a grouping of the formula (e)
- wherein
- R4 has any meaning of R3 or is phenyl which is optionally substituted by chlorine or sulfo;
- W is a CnH2n-alkylene group wherein n is 2 to 6, which is optionally interrupted by 1 or 2 oxygen atoms or an NR5 group, wherein
- R5 has any meaning of R3 or is phenyl, or else when X is fluorine or chlorine, Q can be a group of the formula (a), (b), (c) or (d),
- Y is vinyl or is a grouping of the formula CH2CH2Z wherein
- Z is an alkali-eliminable group.
