This invention concerns water soluble quinacridones of general formula (I) in which Mo is a lithium, sodium, potassium or ammonium cation, and, independent of each other, R?1, R2, R3, and R4¿ are hydrogen, C¿1?-C8-alkyl, C1-C8-alkoxy, carboxyl, C1-C4-alkoxycarbonyl, sulfamoyl, mono- or di-(C1-C4)-alkylsulfamoyl, carbamoyl, mono- or di-(C1-C4)-alkylcarbamoyl, unsubstituted or substituted mono- or diphenylsulfamoyl, unsubstituted or substituted mono- or diphenylcarbamoyl, halogen, nitro or cyano, n is 0, 1, or 2, and m is 0, 1 or 2, and the sum n + m is at least 1. Said quinacridones are used to dye and print natural and synthetic fiber materials.
