A stabilized, concentrated solution of a diazo dye is prepared by coupling diazotized aniline or substituted aniline with a dialkylaniline in the presence of an aromatic solvent. After removal of the aqueous phase, the solution is stabilized by the addition of a branched chain, primary or secondary, C3-C6 alkyl phenol.
