A heterocyclic compound of the formula, ##STR1## wherein A and B are each hydrogen, alkyl or alkoxy, Y is hydrogen, alkyl, alkoxy or --O--R.sup.2 --X--R.sup.1, or Y and B are taken together with each other to form methylenedioxy, R.sup.1 is alkyl, phenyl or alkenyl, R.sup.2 is unsubstituted or substituted alkylene, and X is --O--, --S--, --SO--, --SO.sub.2 -- or ##STR2## in which R.sup.3 is hydrogen or alkyl, with the proviso that R.sup.1 is C.sub.3 or C.sub.4 alkyl or alkenyl, or C.sub.1 -C.sub.4 alkyl when R.sup.2 is unsubstituted ethylene or propylene, respectively, X is --O-- or --S--, and Y and B don't form methylenedioxy, which is useful for dyeing or printing hydrophobic fiber materials with superior dyeability to give a dyed or printed product of a red color excellent in fastness properties, particularly those such as washing fastness.
