Nine dyes with the CH2CH2SC(NH2):NH2+X- group (X = Br, iodine) were prepared and gave fast dyeings on wool in cationic form and on polyesters in disperse form (by decomposition to the thiol immediately before application). P-C6H4(NH2)2 [106-50-3] was acylated with BrCH2CH2COCl [15486-96-1], and the resulting 4-BrCH2CH2CONHC6H4NH2.HCl [57058-91-0] was diazotized and coupled with 1-(2-chlorophenyl)-3-methyl-5-pyrazolone [14580-22-4] to give an azopyrazolone, which was treated with (H2N)2CS to give I [57058-92-1]. The 8 other azo and anthraquinone dyes were prepared as described in Ger. Offen. 1,962,859 (1970). Level dyeings on wool-polyester blends could be obtained by decomposing the dye to the disperse form in an alk. bath, neutralizing, and adding more dye to give a mixture of the cationic and disperse forms. The cationic dyes also readily dyed silk, hair, and acrylic fibers, but their fastness on cellulosics was inadequate. It seems unlikely that the fastness on wool is due to formation of mixed disulfides with cystine units.<\/p>\n

Journal of the Society of Dyers and Colourists published new progress about 14580-22-4. 14580-22-4 belongs to pyrazoles-derivatives, auxiliary class Organic Pigment, name is 1-(2-Chlorophenyl)-3-methyl-5-pyrazolone, and the molecular formula is C10H9ClN2O, Product Details of C10H9ClN2O<\/a>.<\/p>\n
