Abstract

The dyeing performance of some new bisarylazopyrazolo[1,5-a]pyrimidine derivatives 4a-e and 9a,b on polyester fibers has been assisted. It is observed that these dyes have good affinity for polyester fibers. The fastness properties of the dyes on polyester fibers are compared with respect to the position and nature of substituents. The effect of the nature and orientation of substituents in the diazonium component on the color of azodyes is discussed. The newly synthesized compounds were characterized on the basis of elemental analyses and spectral data.
