Dyestuffs of the formula (1) ##SPC1##Wherein A is an optionally substituted radical of the benzene or naphthalene series which, however, does not contain a sulfonic acid group, B is the radical of a coupling component of the benzene, naphthalene, pyrazolone, aminopyrazole, hydroxyquinoline or aceto-acetyl-arylamide series, which, however, does not contain a sulfonic acid group, and R is hydrogen or the lower alkyl.These dyestuffs are very well water-soluble in spite of having a high molecular weight and containing only one sulfonic acid group. They are especially suitable for dyeing or printing materials of natural and synthetic nitrogen-containing fibers, such as wool, silk, polyamide or polyurethane fibers, preferably if dyed from an acid to neutral dye bath. They show a very good colour buildup and migration power when being applied on the material mentioned which allows to obtain even dyeings of good fastnesses to light and to wet processing, for example, to washing and to perspiration.
WHEREIN A is hydrogen, lower alkyl, such as methyl, ethyl, butyl or lower alkoxy, such as methoxy, ethoxy, butoxy, or chlorine; B is hydrogen, lower alkyl such as methyl, ethyl or butyl or lower alkoxy, such as methoxy, ethoxy or butoxy; B1 is lower alkoxy such as methoxy, ethoxy or butoxy; E1 is hydrogen, lower alkyl such as methyl, ethyl, butyl or lower alkoxy such as methoxy, ethoxy or butoxy, E2 is hydrogen, lower alkyl such as methyl or ethyl, lower alkoxy such as methoxy or ethoxy; R is lower alkyl of 1 to 4 carbon atoms, such as methyl, ethyl, propyl or butyl and OR is either ortho or para to the azo linkage; and -SO3H is either meta or para to A, provide yellow to scarlet dyeings of very good fastness and dyeing properties and excellent leveling characteristics on natural and synthetic polyamide fibers.
