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.
