Compounds of the formula ##STR1## in which R.sub.1 is C.sub.1-4 alkyl, Hal is halogen, R.sub.2 is ##STR2## --SO.sub.2 C.sub.1-4 alkyl, --SO.sub.2 NR.sub.8 R.sub.9 or --NHCOOR.sub.10, R.sub.3 is hydrogen, C.sub.1-4 alkyl or C.sub.1-4 alkoxy, R.sub.4 is hydrogen or C.sub.1-4 alkyl, R.sub.5 is hydrogen; C.sub.1-4 alkyl; cyclohexyl; cyclohexyl substituted by one to three C.sub.1-4 alkyl groups; phenyl or phenyl substituted by one or two substituents selected from halo, C.sub.1-4 alkyl and C.sub.1-4 alkoxy, R.sub.6 is hydrogen or hydroxy, with the proviso that R.sub.6 is hydrogen when R.sub.2 is --NHCOOR.sub.10, R.sub.7 is hydrogen, C.sub.1-4 alkyl or C.sub.1-4 alkoxy, each of R.sub.8 and R.sub.9, independently, is hydrogen, C.sub.1-4 alkyl, C.sub.2-4 hydroxyalkyl, cyclohexyl; or phenyl or phenyl substituted by one or two substituents selected from halo, C.sub.1-4 alkyl, C.sub.1-4 alkoxy, sulfo and carboxy, with the proviso that not more than one of R.sub.8 and R.sub.9 is cyclohexyl, phenyl or substituted phenyl, R.sub.10 is C.sub.1-6 alkyl, the triazinylamino group is in the 4-position when R.sub.2 is --NHCOOR.sub.10 and otherwise is in the 4- or 5-position, m is 1 or 2, n is 0 or 1, and p is 0 or 1, and the molecule contains at least two sulpho groups, and mixtures of such compounds, which compounds are in free acid or salt form and are useful as reactive dyes for dyeing and printing hydroxy group-containing and nitrogen-containing organic substrates such as leather and textile materials consisting of or comprising natural or regenerated cellulose (for example, cotton, viscose and spun rayon) or natural or synthetic polyamides (for example, wool, silk and nylon. The obtained dyeings and prints have notable fastness to light, washing, water, sweat and milling. The combination dyeings obtained when used in combination with other sulfo group-containing reactive dyes are tone-in-tone, resist catalytic fading and exhibit good fastness to light and wet treatments.
A compound of the formula ##STR38## or a salt thereof each cation of which is non-chromophoric, wherein R.sub.1 is C.sub.1-4 alkyl,
