Abstract: Twenty-two azo dyes have been prepared by coupling 2-cyanomethyl-4(3H)-quinazolinone with various aniline derivatives and their dyeing performance as disperse dyes has been assessed on polyester, nylon and cellulose triacetate fibres. These dyes have been found to give a wide range of colour shades varying from yellow to orange to brown with very good depth and levelness on each fibre. The percentage dye bath exhaustion on different fibres has been found to be reasonably good and acceptable. The dyed fibres show good fastness to washing, rubbing, perspiration and sublimation. A remarkable degree of levelness after washing indicates good penetration and affinity of these dyes to the fibres. Some of the selected dyes have also been characterized by TGA for their better thermal stability.
