Abstract: Abstract A new synthetic route was developed to create azo based dispersed dyes which are derived from 3-(3-Chloropheney)-2-((4-substituted) diazenyl)-3-oxopropanenitrile and 3-substituted 5-amino-4-arylazopyrazoles. The new dyestuff was used to dye unmodified polypropylene fabrics under both aqueous… read more here.
