Abstract: Dye formulations for dyeing and printing cellulose and cellulosic textile material which in addition to conventional components contain a dye of the general formula (I): (I) in which D is the radical of a diazo component; R is hydrogen, C1 to C7 alkyl, phenyl or phenyl bearing methyl as a substituent; X is cyano, carbamoyl or substituted carbamoyl; R1 is hydrogen or an aliphatic, cycloaliphatic, araliphatic or aromatic radical; R2 is hydrogen or an aliphatic, cycloaliphatic or araliphatic radical; R3 and R4 independently of one another have the same meanings as R1 and R2; and R1-N-R2 and R3-N-R4 independently of one another are saturated heterocyclic radicals.

Abstract: Compounds of the general formula I I where R1 and R2 independently of one another are each C6-C24-alkyl or are each benzyl which is unsubstituted or substituted by alkyl or by cycloalkyl, and one of the radicals may furthermore be hydrogen, and the rings A, B, C and D can be further substituted by chlorine, methyl or methoxy, with the exception of the compound of the formula +TR are useful as dyes in electrooptical liquid crystal displays or for the production of polarization films.

Abstract: The novel compounds of the general formula I I where A is a radical of a coupling or diazo component which, if necessary after conversion, is capable of complex formation, Ar is an unsubstituted or substituted aromatic or heterocyclic radical, D is a radical of a diazo component and Me is a Co2+, Cu2+, Zn2+, Mn2+ or Ni2+ ion, and the ring B can be further substituted, are very useful for dyeing cellulose fibers, polyesters and blends of cellulose fibers and polyesters. The present dyes are lightfast and fast to washing and to solvents.

Abstract: The invention relates to compounds of the formula I in which n is 1 or 2, R is optionally substituted alkyl, cycloalkyl, aralkyl or aryl, and Y is a radical of the formula where the rings A, B and C may also be substituted and fused to a benzene ring, and where R and R are hydrogen or optionally substituted alkyl, aralkyl or cycloalkyl or, together with the nitrogen, are piperidino, pyrrolidino or morpholino, R is optionally substituted alkyl, cycloalkyl, aralkyl, aryl, acyl, alkoxy- or aroxycarbonyl or arylsulfonyl and, R is hydrogen, alkyl or cycloalkyl. The compounds according to the invention are suitable as dyes for liquid crystals and polarising films.
