ABSTRACT OF THE DISCLOSURE Dyestuffs consisting of the mixture of isomers of the formulae Image and Image wherein R1 is hydrogen, alkyl with 1 to 20 carbon atoms, alkoxyalkyl or alkoxycarbonyl alkyl each with 1 to 4 carbon atoms per alkyl moiety, benzyl, alkoxycarbonyl with 1 to 20 carbon atoms per alkyl moiety or phenyl, R2 is alkoxycarbonyl with 1 to 20 carbon atoms per alkyl moiety, cyano, alkanoyl or alkoxyalkoxycarbonyl each with 1 to 4 carbon atoms per alkyl moiety, carbonamido, phenylcarbonamido, mono- or dialkylcarbonamido with 1 to 8 carbon atoms per alkyl moiety or cyclohexylcarbonamido, R3 and R4 are identical and are hydrogen or alkoxy with 1 to 4 carbon atoms or R3 is alkoxy with 1 to 4 carbon atoms and R4 is hydrogen and R is phenyl- thio which may be substituted by one or two chlorine or bromine atoms or alkyl, alkoxy, carbalkoxy or alkylsulfonyl groups each having 1 to 4 carbon atoms per alkyl moiety or a cyano, trifluoromethyl or nitro group; naphthylthio, pyridinethio, benzimidazolyl-2-thio, benzoxazolyl-2-thio, benzthiazolyl-2-thio or an amino group of the formula Image wherein R5 and R6 represent hydrogen, alkyl or hydroxyalkyl each with 1 to 4 carbon atoms or phenyl, or together are piperidine, morpholine or piperazine. The new dyestuffs are very suitable for the dyeing of synthetic materials such as polyethylene-glycol torephthalate, acetyl cellulose or polyamides. They yield brilliant greenish yellow to orange red shades which have a good fastness to light and to thermofixation. They are also very suitable for the dyeing of fibre-forming polymers such as for example polyethylene-glycol terephthalate in the mass. Furthermore, a big part of the dyestuffs can be used for dyeing synthetic fibre materials sucll as polyester fibres from organic solvents, for example perchloroethylene.
