    摘要: 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.

    摘要: Disclosed are monoazo dyes derived from diazotized 5-amino-4-halo-3-methylisothiazoles and m-acylaminoaniline couplers. These dyes impart scarlet and red shades on nylon and polyester fibers and exhibit good fastness properties. The dyes are represented by the general formula: ##STR1## wherein R.sub.1 and R.sub.2 are each selected from lower alkyl, cycloalkyl, substituted cycloalkyl, or lower alkyl substituted with phenyl, cyano, sulfonamido, carboxamido, alkoxy, hydroxy, or an imide radical; R.sub.3 is lower alkyl, lower alkyl substituted as above, phenyl, or trifluoromethyl; and X is chlorine or bromine.
