Document Language : English 
Abstract : . Diazocoupling of 1-phenyl-3-trifluoromethyl-2-pyrazolin-5-one (1) with different aryldiazonium salts yielded 4-[(aryl)diazenyl]-1-phenyl-3-trifluoromethyl-2-pyrazolin-5-ones (2) as coloured products. The new synthesized azo-dyes have been extensively employed on wool, silk, cotton and polyester textiles to give bright fast dyes ranges from yellow to deep violet colours, which are stable to laundry and exposure to sun light.
