ABSTRACT:
Disclosed are azo dyes containing diazonium moieties from aminothiazoles, aminoisothiazoles, or aminothiadiazoles (1,2,4- or 1,3,4-), and certain coupler moieties from aniline, tetrahydroquinoline, and benzomorpholine type compounds, wherein the diazonium moieties have at least one cinnamoyl group, and wherein a wide variety of groups, e.g., one or more water-solubilizing substituents such as sulfonic acid groups or their metal or amine salts may be present in the dye molecule. These dyes are useful for dyeing materials selected from polyamide, cellulose ester, polyester, wool and other natural and synthetic fibers and generally exhibit improvements in dyeability and fastness properties.
