ABSTRACT:
A compound having the formula ##STR1## wherein A denotes an optionally substituted aromatic, isocyclic or heterocyclic residue; R is H, an alkyl residue having from 1 to 6 carbon atoms, an aryl residue having from 6 to 10 carbon atoms or an aralkyl residue having from 7 to 10 carbon atoms; Q is H or a methyl group; X and Y are the same or different and each is a non-water solubilizing group, or X and Y together form a fused aromatic ring system; and R.sub.1 and R.sub.2 are the same or different and each is H or an alkyl radical having from 1 to 22 carbon atoms, and R.sub.3 is hydrogen, an alkyl radical having from 1 to 22 carbon atoms or an aryl radical having from 6 to 10 carbon atoms, the alkyl radicals in R.sub.1, R.sub.2 and R.sub.3 being unsubstituted and uninterrupted or being substituted by an OH, NH.sub.2 or CN group and/or being interrupted by an ethylenic group or an oxygen, sulphur or nitrogen bridge, or two or all three of R.sub.1, R.sub.2 and R.sub.3 may form, together with the nitrogen atom to which they are attached, a heterocyclic residue, is useful for pigmenting high molecular weight organic material such as a natural or synthetic polymer or copolymer, or a coating composition for application to the surface of an article, or a printing liquid medium to yield shades from greenish yellow to red brown, exhibiting good fastness properties.
