Abstract : Aldol condensation of 4-Acetyl-[4-dimethylamino and phynylamino] azobenzene with various aromatic aldehydes gave the corresponding chalcone-derived azo dyes. The new dyes showed a broad absorptions in the visible region with medium intensities. The halochromism of these new dyes were investigated and found in accordance with the resonance theory.
