Abstract
Abstract A heterocyclic compound of the formula, wherein A and B are each hydrogen, halogen, alkyl or alkoxy, R¹ is alkylene having upto 6 carbon atoms, X is direct linkage or divalent group such as -O-, -S- and the like, T and U are each hydrogen or alkyl, ℓ is 0 or 1 to 3, Q is 5-, 6- or 7- membered saturated or unsaturated heterocyclic residue, and Y is hydrogen, halogen, alkyl, alkoxy or or Y and B are taken together with each other to form methylene-dioxy, 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.
