Diarylide yellow pigment compositions which are sulfonated with 2,2'disulfobenzidine and/or p-sulfo-acetoacetanilide are rendered hydrophobic by treatment with specific quaternary ammonium salts. The pigment compositions are easily flushed into flushed bases. When incorporated into printing inks, the pigments demonstrate improved color strength and transparency.
