Research on Some Brown Iron Complex Azo Dyes

摘要

Some novel 1:1 and 1 ：2 Fe complex azo dyes were synthesized in this study.The mass spectrum analysis of 1:1 and 1:2 Fe complex azo dyes is presented.Lightfastness,rubbing fastness and washing fastness of these metallized complex dyes were evaluated for use on wool.Results show that these dyes are of good lightfastness and satisfactory brown shades.
