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; PA1 X is --NH or a direct bond; and PA1 Y is --NH, --CONH, --NHCO or a direct bond; and Wherein 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.
