    Abstract: Dye mixtures, containing dyes of the formula I I where X is hydrogen, chlorine or bromine, R1 is hydrogen, methoxy, ethoxy or phenoxy, R2 is hydrogen, methyl, ethyl, n-propyl or iso-propyl and R is where R3 is allyl, methallyl, crotonyl, prenyl or benzyl, R4 is C1-C5-alkyl, allyl, methallyl, crotonyl, prenyl or benzyl and R4 is C1-C5-alkyl, the mixtures containing not less than 60% of dyes wherein R is or NHC2H4CN, from 0 to 40% of one or more dyes wherein R is and from 0 to 40% of one or more dyes wherein R is the two last-mentioned components accounting for not less than 5% of the mixture. The mixtures are exceptionally useful for dyeing polyesters.

    Abstract: Novel dyes of the formula where A is cyano, carbo-C1-C4-alkoxy, carbamyl, N-C1-C4-alkylcarbamyl, N-phenylcarbamyl, acetyl, benzoyl, 4-nitrophenyl or 4-cyanophenyl, X is hydrogen, chlorine, C1-C4-alkyl or C1-C4-alkoxy, and if n is 2 the substituents may be identical or different, n is 1 or 2, R1 is hydrogen, methyl, ethyl or 2-hydroxyethyl and R2 is phenyl or cyclohexyl, or R1 is hydrogen and R2 is C1-C4-alkyl, or R1 and R2 are C1-C6-alkyl, allyl or phenyl-C1-C4-alkyl or the group is a saturated heterocyclic five-membered or six-membered ring which may additionally contain an oxygen or a further nitrogen as ring members, Y is hydrogen, hydroxyl, methyl or ethyl; where R3 is linear or branched C1-C12-alkyl, or is phenyl; where R4 is hydrogen or C1-C4-alkyl and R5 is hydrogen, linear or branched C1-C12-alkyl or trifluoromethyl; chloromethyl; C1-C4-alkoxymethyl, phenoxymethyl, benzyl, phenylethyl, C3-C7-cycloalkyl, phenyl, H5C6-CH=CH- or -CH2-PO(OR6)2, where R6 is C1-C4-alkyl; or where R7 is C1-C12-alkyl, phenyl or C1-C12-alkylphenyl; or Y is N-C1-C4-alkylamino if R1 and R2 are C1-C4-alkyl, or Y is N,N-di-C1-C4-alkylamino, N-pyrrolidinyl, N-piperidinyl or N-morpholinyl if has the same meaning, and Z is hydrogen or, if R1 and R2 are C1-C4-alkyl or allyl and Y is Z is hydrogen, methoxy or ethoxy, and alkyl, phenyl, phenoxy and phenylthio may contain additional substituents. The dyes give blue to violet hues on synthetics, in particular on linear polyester fibers. Where Z is methoxy or ethoxy, greenish blue dyeings are obtained. The dyeings are very deep, clear and brilliant. Some of the dyes may also be used for the mass coloring of thermoplastics.
