Disperse and acid azo dyes having one or two cinnamoyl substituents on a phenyl diazonium moiety and containing an aniline, tetrahydroquinoline or benzomorpholine coupler

This invention relates to azo dyes which may be unsubstituted or substituted with a variety of groups known to the dye art, and containing a diazonium moieties from an aniline type compound and certain coupler moieties from aniline, tetrahydroquinoline, or benzomorpholine compounds, wherein the diazonium moiety has 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.
