Resumo Inglês:
Ten hot brand bisazo reactive dyes (D1 to D10) have been synthesized by coupling bis(diazotised), 4,4'-methylene bis(2,6-dichloroaniline) (A) with various 5-sulfo anthranilo cyanurated coupling components (R) and their dyeing performance as reactive dyes has been assessed on silk, wool and cotton fibres. The purity of dyes was checked by TLC. The IR spectra and 1H-NMR spectra prove the structure of newly reactive dyes. The percentage dye bath exhaustion on different fibres was reasonable good and acceptable. The dyes exhibited high levels of light, washing and rubbing fastness.
