Abstract
Disclosed are novel azo dyes containing an isothiazole diazo moiety which may be substituted, and a tetrahydroquinoline coupler which also may be substituted. The dyes produce red to violet shades on, for example, hydrophobic textile fiber including polyesters, polyamides, and cellulose esters and have excellent properties including lightfastness, washfastness and resistance to sublimation, and dye at unusually low energy levels. The dyes have the general formula ##STR1## wherein the various substituents, R.sup.1 through R.sup.9, are selected from a wide variety of groups such as alkyl, --CN, halogen, alkoxy, and the like.
