“…The absorption ability of these dyes substituted with electronwithdrawing and electron-donating groups at their o-, m-and p-positions was examined in detail. 116 These synthesized yellow-red dyes were applied to PLA, PET, and polyamide (PA) 6.6 fibers, resulting in quite high color yield on PLA and PET fabrics with high K/S values leading to medium to heavy depth of shades at only 2% dye concentration. PLA and PET fabrics presented higher color strength and darker shades than PA 6.6 fabrics, while the light fastness of PET fabric was better than PLA and PA 6.6 fabrics.…”

“…The studies in which pyrazole has been used as a heterocyclic coupling component have grown in importance and are frequently encountered in the literature, especially in recent years. 16,[18][19][20][21][22][23] The fact that the various pyrazole derivatives have been used in pharmacology, agricultural chemistry and the dye industry has resulted in the improvement of new synthetic procedures for the synthesis of these compounds. Condensation of β-enaminonitriles and β-ketoesters with hydrazine is one of the most widely used methods for the synthesis of aminopyrazoles and pyrazolones, respectively.…”

“…Due to their chemical significance and spectroscopic properties, hetarylazo dyes were studied extensively by spectroscopic and theoretical methods. Their higher tinctorial strength and brighter dyeing make azo dyes based on heterocyclic amines superior than aniline based azo dyes [23][24][25][26][27][28]. Some hetarylazopyrazolone dyes have not only potential use as dye stuff, but also other potential nontextile applications such as optical materials [29].…”
