Abstract
Synthesis of some 2,6-diamino-4-(p-arylazo)anilinopyrimidine (IIIa-c) and 2 ,6-diamino-5-(arylazo)-4-(p-arylazo)anilinopyrimidine (IVa-h) are described . Compounds IIIa-c were synthesized by condensation of 2,6-diamino-4-chloro pyrimidine (I) with the appropriate aminoazobenzene (IIa-c), while compound s IVa-h by coupling IIIa with diazotized arylamines. The effects of the nat ure and orientation of the substituents on the colour and dyeing properties of these dyes on polyester and acrylic fibres were evaluated.
