The Synthesis and Optical Absorption of Bisazo Pigments from 1,5-Diaminoanthraquinone

Department of Chemistry, Zhejiang University, Hangzhou 310027

Received Date: 3 November 1997

Fund Project: This research was supported by Zhejiang Provincial Natural Science Foundation of China.

Ten new bisazo pigments were synthesized by coupling 1,5-diaminoanthraquinone with various couplers. The absorption studies show that a red shift of 50 nm is obtained when the coupler component is changed.
