Compounds of the formula <IMAGE> (I) in which K is the radical of a coupling component of the aniline, alpha -naphthylamine, pyrazolone, aminopyrazole, indole, tetrahydroquinoline, thiazole, phenol, naphthol, pyridine or pyridone series. R is -CHO, -CH=C(CN)-R1, -CH=CH-R2, -CH=C(NO2)-R3, -CH=NOH or -CN, wherein R1 is (C1-10alkoxycarbonyl; (C1-10alkoxy)carbonyl monosubstituted by chloro, bromo, cyano, hydroxy, C1-2alkoxy, (C1-2alkyl)carbonyloxy or (C1-2alkoxy)carbonyl; (C1-10alkoxy)carbonyl disubstituted by hydroxy and by chloro or bromo; (C3-8alkenyl)oxycarbonyl; (C3-8chloroalkenyl)oxycarbonyl; (C3-8bromoalkenyl)oxycarbonyl; propynyloxycarbonyl; benzyloxycarbonyl; chlorobenzyloxycarbonyl; nitrobenzyloxycarbonyl; C1-4alkylsulfonyl; phenylsulfonyl; tolylsulfonyl; carbamoyl; (C1-2alkyl)carbamoyl; di(C1-2alkyl)carbamoyl; phenylcarbamoyl; aminothiocarbonyl; benzimidazolyl-2; cyano; acetyl; phenyl; benzoyl or phenyl or benzoyl substituted by 1, 2 or 3 substituents each of which is independently chloro, bromo or nitro, with the proviso that the maximum number of nitro groups is two, and R2 is phenyl; benzoyl or phenyl or benzoyl substituted by 1, 2 or 3 substituents each of which is independently chloro, bromo or nitro, with the proviso that the maximum number of nitro groups is two, and R3 is hydrogen, methyl or ethyl, and m is 0 or 1, useful as disperse dyes for dyeing and printing textile substrates comprising or consisting of synthetic or semi-synthetic, hydrophobic, high molecular weight, organic materials such as linear aromatic polyesters, cellulose 21/2 acetate, cellulose triacetate and synthetic polyamides, with those wherein R is formyl also being useful for dyeing wool.
