Abstract: Novel sulfonated quinolone compounds used in the preparation of fiber reactive dyes having the formula: ##STR1## being N-alkyl substituted-4-hydroxy-6-sulfo-2-quinolone. The alkyl group bonded to the nitrogen in the quinolone has from 1 to 4 carbon atoms which may be further substituted by an hydroxy, amino, or sulfo group.
