Abstract
Reactive dyes of the formula ##STR1## where m is 0 or 1, A.sup.1 and A.sup.2 are different and each is a fiber-reactive radical or else, in the case of A.sup.2, hydrogen, D.sup.1 and D.sup.2 are substituted or unsubstituted phenylene, substituted or unsubstituted phenylenemethyl, substituted or unsubstituted naphthylene or substituted or unsubstituted naphthylenemethyl, K.sup.1 and K.sup.2 are each the radical of a coupling component of the aminonaphthalenesulfonic acid series and L is a bridge member, are useful for dyeing and printing hydroxyl- or nitrogen-containing substrates.
Claims7
A reactive dye of the formula I ##STR106## where m is 0 or 1,
- A.sup.1 and A.sup.2 are different from each other and each is an additively fiber-reactive radical or a substitutively fiber-reactive radical or else, in the case of A.sup.2, hydrogen, with the proviso that no more than one of A.sup.1 and A.sup.2 is a substitutively fiber-reactive radical and no more than one of A.sup.1 and A.sup.2 is an additively fiber-reactive radical,
- D.sup.1 and D.sup.2 are identical or different and each is independently of the other substituted or unsubstituted phenylene, substituted or unsubstituted phenylenemethyl, substituted or unsubstituted naphthylene or substituted or unsubstituted naphthylenemethyl,
- K.sup.1 and K.sup.2 are identical or different and each is independently of the other the radical of a coupling component of the aminonaphthalenesulfonic acid series, and L is a bridge member.
A reactive dye which conforms to the formula Ia ##STR107## where V is 2-chloroethylsulfonyl or a 2-hydroxyethylsulfonyl radical which has been esterified with an inorganic or organic acid and forms vinylsulfonyl under dyeing conditions,
- S is a substitutively fiber-reactive radical, D.sup.1 and D.sup.2 are identical or different and each is independently of the other substituted or unsubstituted phenylene, substituted or unsubstituted phenylenemethyl, substituted or unsubstituted naphthylene or substituted or unsubstituted naphthylenemethyl, K.sup.1 and K.sup.2 are identical or different and each is independently of the other the radical of a coupling component of the aminonaphthalenesulfonic acid series, and L is a bridge member.
A reactive dye which conforms to the formula Ib ##STR108## where V is a 2-hydroxyethylsulfonyl radical which has been esterified with an inorganic or organic acid and forms vinylsulfonyl under dyeing conditions, D.sup.1 and D.sup.2 are identical or different and each is independently of the other substituted or unsubstituted phenylene, substituted or unsubstituted phenylenemethyl, substituted or unsubstituted naphthylene or substituted or unsubstituted naphthylenemethyl,
- K.sup.1 and K.sup.2 are identical or different and each is independently of the other the radical of a coupling component of the aminonaphthalenesulfonic acid series, and L is a bridge member.
A reactive dye which conforms to formula Ic ##STR109## where S is a substitutively fiber-reactive radical, D.sup.1 and D.sup.2 are identical or different and each is independently of the other substituted or unsubstituted phenylene, substituted or unsubstituted phenylenemethyl, substituted or unsubstituted naphthylene or substituted or unsubstituted naphthylenemethyl, K.sup.1 and K.sup.2 are identical or different and each is independently of the other the radical of a coupling component of the aminonaphthalenesulfonic acid series, and L is a bridge member.
