Abstract

Importance of heterocyclic dyes has recently increased due to their deep shades, high tentorial strength, excellent colorfastness and brightness compared to azobenzene analogous. Development of novel synthetic approaches for fused heterocyclic dyes has remained a highly interesting but challenging proposition. An overview of the application of nitrogen-containing fused heterocyclic dyestuffs for textile coloration is presented. In this review, we provide details outlining the synthesis of recently prepared fused nitrogen-containing heterocyclic dyestuffs and their dyeing efficiency on textile fibers.
