Compounds of the formula <IMAGE> wherein R1 is nitro or cyano; R2 is cyano or halo; R3 is C1-4alkyl; R4 is methyl or ethyl; R5 is C1-8alkyl; and R6 is -CH2CHOHCH2O(CH2CH2O)aR7, -CH2CHOHC6H5, -CH(C6H5)CH2OH; -(CH2)nO-CO-NHR3, -CH2CH(R4)-O-CO-NHR3; -(CH2)n-O-CO-R3, -CH2CH(R4)-O-CO-R3 or C2-4hydroxyalkyl, with the provisos that R6 may be any of the last three groups only when R1 and R2 are both cyano and that R6 may be C2-4hydroxyalkyl also when R5 is C1-2alkyl, wherein R7 is phenyl; phenyl substituted by 1 or 2 substituents independently selected from hydroxy, chloro, bromo, methyl and C1-4alkoxy; benzyl; benzyl substituted by 1 or 2 substituents independently selected from hydroxy, chloro, bromo, methyl and C1-4alkoxy; allyl; haloalkyl; propyn-2-yl or halopropyn-2-yl, with the proviso that R7 may be allyl, haloallyl, propyn-2-yl or halopropyn-2-yl only when a is 0; a is 0 or 1; and n is 2 or 3, processes for their preparation and their use for dyeing and printing textiles comprising synthetic or semi-synthetic, hydrophobic, high molecular weight materials, e.g., linear aromatic polyester, cellulose 21/2 acetate, cellulose triacetate and synthetic polyamides, by, for example, the rapid dyeing procedure.
