In this study 5-amino-4-arylazo-3-methyl-1H-pyrazoles (1a-1m) were diazotised and coupled with 3amino-5-hydroxy-1-phenylpyrazole to give disperse disazo dyes (2a-2m). The newly synthesized 13 disperse disazo dyes were characterized by elemental analysis and spectral methods. The solvatochromic behav
