This invention relates to azo dyes which may be unsubstituted or substituted with a variety of groups known to the dye art, and containing diazonium moieties from 2-aminobenzothiazole or 2-aminobenzisothiazole type compounds, and certain coupler moieties from aniline, tetrahydroquinoline, or benzomorpholine compounds, wherein the diazonium moieties have one or two cinnamoyl substituents, and wherein one or more water-solubilizing groups such as a sulfonic acid group or its metal or amine salt may be present as a substituent in the dye molecule for acid dyeing. These dyes are particularly useful in dyeing one or more of polyamide cellulose acetate polyester, wool and other fibers.
