Pyridazine derivatives and its related compounds. Part 31. Synthesis of some disperse dyes derived from 3-amino-1H-pyrzolo[3,4-c]pyridazine and their color assessment on polyester fabrics

Pyridazine and its related compounds: Part 33. Synthesis of some disperse dyes derived from 3-hydrazinyl-4,5-diphenyl-1H-pyrazolo[3,4-c]pyridazine and their color assessment on polyester fabric

“…All of them were investigated for their dyeing characteristics on polyester. The dyed fabrics exhibit good to excellent (4)(5) washing, perspiration, rubbing and sublimation fastness properties. The remarkable degree of levelness and brightness after washings is indicative of good penetration and the excellent affinity of these dyes for the fabric due to the accumulation of polar groups.…”

“…Also, they are used as key starting material for the synthesis of commercial aryl/ hetarylazopyrazole dyes [4]. All these properties aroused our interest in synthesis new heterocyclic compounds including the pyrazolo [3,4-c]pyridazine moiety which is a continuation of our previous work [5][6][7][8][9].…”

Application of some novel pyrazole disperse dyes to synthetic fabrics

“…in the medical field [12][13][14][15][16][17][18][19][20][21]. Besides, it is widely used for dyeing synthetic based fabrics for textile industry due to their wide and different color choices [22][23][24][25]. Color and color fastness characteristics of synthetic fibers dyed with these dyes displayed satisfying results [26][27][28][29][30][31].…”
