The present invention relates to para-substituted-amino-.beta.,.beta.-dicyano- or .beta.-cyano-,.beta.-acyl-distyryl disperse dyes in which the benzene nuclei of the two styryl radicals are connected by a bridge member.
Methine transfer dyes have the formula ##STR1## where L is a bridge member which does not permit any conjugation of .pi.-electrons between Z and Y, X is cyano, C.sub.1 -C.sub.6 -alkoxycarbonyl or C.sub.1 -C.sub.6 -monoalkylcarbamoyl, wherein alkyl may in each case be interrupted by oxygen atoms, or is C.sub.5 -C.sub.7 -cycloalkoxycarbonyl, C.sub.5 -C.sub.7 -monocycloalkylcarbamoyl, phenoxycarbonyl or monophenylcarbamoyl, and Y and Z are each independently of the other aminophenylene, which may be benzo-fused, or heterocyclyl.
Bichromophoric methine and azamethine transfer dyes have the formula 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.
