Abstract
Bichromophoric methine and azamethine transfer dyes have the formula Z.sup.2 --Z.sup.1 --LY.sup.1 --Y.sup.2 where L is a bridge member which does not permit any conjugation of .pi.-electrons between Z.sup.1 and Y.sup.1, Y.sup.1 and Z.sup.1 are each independently of the other aminophenylene, which may be benzofused, or heterocyclyl and Y.sup.2 and Z.sup.2 are each independently of the other benzoquinoeiminyl, which may be benzofused, or heterocyclyl.

A bichromophoric dye of the formula I
- Z.sup.2 --Z.sup.1 --L--Y.sup.1 --Y.sup.2 (I)
- where
- L is a bridge member which does not permit any conjugation of .pi.-electrons between Z.sup.1 and Y.sup.1, said bridge member having the formula
- --E.sup.1 --D--E.sup.2 --
- where
- D is a chemical bond, oxygen, --SO.sub.2 --, --O--CO--O--, 1,4-cyclohexylene, phenylene, --O--CO--(CH.sub.2).sub.1 --CO--O, --O--(CH.sub.2).sub.m --O--, ##STR83## where 1 is from 1 to 10 and m is from 2 to 10, ##STR84## E.sup.1 and E.sup.2 are identical or different and each is independently of the other a chemical bond or C.sub.1 -C.sub.15 -alkylene,
- Z.sup.1 and Y.sup.1 are identical or different and, together with the bridge member L, each is independently of the other a radical of the formula ##STR85## where R.sup.1 and R.sup.5 are identical or different and each is independently of the other alkyl, alkoxyalkyl, alkoxycarbonylalkyl or alkanoyloxyalkyl, which may each have up to 10 carbon atoms and be hydroxyl- or cyano- substituted, hydrogen, benzyl, cyclohexyl, phenyl or tolyl,
- R.sup.2 and R.sup.3 are identical or different and each is independently of the other hydrogen, C.sub.1 -C.sub.8 -alkyl, C.sub.1 -C.sub.6 -alkoxy, C.sub.1 -C.sub.6 -alkanoylamino or C.sub.1 -C.sub.6 -alkylsulfonylamino,
- Z.sup.2 and Y.sup.2 are identical or different and each is independently of the other a radical of the formula ##STR86## where R.sup.7 is C.sub.1 -C.sub.6 -alkoxycarbonyl, C.sub.1 -C.sub.6 -monoalkylcarbamoyl, C.sub.1 -C.sub.6 -monoalkylsulfamoyl, C.sub.1 -C.sub.6 -alkanoylamino or C.sub.1 -C.sub.6 alkylsulfonylamino, wherein alkyl may in each case be interrupted by 1 or 2 oxygen atoms, or C.sub.5 -C.sub.7 -cycloalkoxycarbonyl, C.sub.5 -C.sub.7 -monocycloalkylcarbamoyl, C.sub.5 -C.sub.7 -monocycloalkylsulfamoyl, C.sub.5 -C.sub.7 -cycloalkylcarbonylamino, phenoxycarbonyl, monophenylcarbamoyl, monophenylsulfamoyl, benzoylamino, phenylsulfonylamino, methylphenylsulfonylamino, fluorine or chlorine,
- R.sup.8 is C.sub.1 -C.sub.8 -alkyl, C.sub.1 -C.sub.6 -alkanoylamino or C.sub.1 -C.sub.6 -alkylsulfonylamino, wherein alkyl may in each case be interrupted by 1 or 2 oxygen atoms, or C.sub.5 -C.sub.7 -cycloalkylcarbonylamino, C.sub.5 -C.sub.7 -cycloalkylsulfonylamino, benzoylamino, phenylsulfonylamino, hydrogen, fluorine or chlorine.
