Abstract
Abstract Azo dyestuff sulfonic acid salts of the formula: ##STR1## wherein A represents a carbocyclic or heterocyclic aromatic radical, B represents an aliphatic, cycloaliphatic or araliphatic amine, X represents a hydrogen atom or a substituted or unsubstituted alkyl group, a cycloalkyl, aralkyl or aryl group, Y represents a hydrogen or halogen atom, a nitro, cyano, acyl, sulfonic acid, arylsulfonyl, alkoxycarbonyl group or a substituted or unsubstituted alkyl, sulfamoyl or carbamoyl group, Z represents a substituted or unsubstituted alkyl group or an aryl radical, m and n are 1 or 2; said dyestuffs salts having good solubility in organic solvents and functioning to color solutions of film forming polymers in yellow to orange shades.
