Abstract: A monoazo dye or pigment of the formula: ##STR1## in which D is the radical of the diazo component, preferably a diazotized compound of the aminoanthraquinone, aminophthalimide or aniline series;X is --NH or a direct bond; andY is --NH, --CONH, --NHCO or a direct bond; andWherein the rings A and B may contain from one to three substituents such as chloro, bromo, methyl, ethyl, methoxy, ethoxy, cyano, nitro, alkoxycarbonyl, trifluoromethyl, methylsulfonyl and optionally N-substituted carbamoyl or sulfamoyl radicals. The dyes or pigments are eminently suitable for coloring for example printing inks, surface coatings and resins because of their color strength and very good fastness properties.

Abstract: Dyes of the formula: ##STR1## in which D is the radical of a diazo component;R.sup.1 is hydrogen, chloro, bromo, methoxy or ethoxy;R.sup.2 and R.sup.3 independently of one another are hydrogen, chloro, bromo, methyl, ethyl, trifluoromethyl, nitro, methylsulfonyl, ethylsulfonyl, phenylsulfonyl, unsubstituted or N-substituted carbamoyl or sulfamoyl, carboxylic ester, unsubstituted or substituted C-acylamino or phthalimidyl; orR.sup.2 and R.sup.3 together form a radical of the formula: ##STR2## The dyes are eminently suitable for coloring printing inks, surface coatings and resins with excellent fastness properties.
