Isothiazoleazo dyes I ##STR1## where R.sup.1 is H, halogen, C.sub.1 -C.sub.4 -alkyl or C.sub.1 -C.sub.4 -alkoxy and A is the radical of a coupling component are used predominantly as disperse dyes for dyeing hydrophobic organic fibers and fiber materials.
摘要:
Azo dyes having the general formula ##STR1## in which each of X, Y and Z are independently selected from H and a variety of substituents, preferably provided that at least one of X and Y is a substituent selected, for example, from --CN, halogen, alkyl, and alkylsulfonyl, and C is the residue of a phenol, naphthol, indole, imidazothiazole, pyrazolone, thiazole, isothiazole or pyrazole type disperse dye coupling component. These dyes which are unexpectedly non-phototropic produce yellow to orange shades on hydrophobic fibers and exhibit improvements in one or more properties such as dyeability, dye exhaustion rate, light fastness, nonblooming, pH stability, build, fastness to ozone and nitrogen oxide, crock and wash fastness, migration, transfer, and pH stability on polyester, polyamide and other fibers including cellulose ester.
