Abstract
Dyes of formula ##STR1## wherein D is the radical of a diazo component of the benzene or naphthalene series or of the heterocyclic series, R.sub.1 is hydrogen or C.sub.1 -C.sub.4 alkyl and R.sub.2 is phenyl or substituted phenyl, give dyeings of good fastness properties on nitrogen-containing or hydroxyl group containing fibre materials.
Claims6
A dye of the formula ##STR67## wherein D is the radical of a diazo component of the benzene or naphthalene series or of the heterocyclic series, R.sub.1 is hydrogen or C.sub.1 -C.sub.4 alkyl and R.sub.2 is unsubstituted phenyl or phenyl which is substituted by C.sub.1 -C.sub.4 alkyl, C.sub.1 -C.sub.4 alkoxy, C.sub.2 -C.sub.4 alkanoylamino or halogen, and wherein the dye of formula (1) contains only one sulfo group.
A compound of the formula ##STR71## wherein R.sub.1 is hydrogen or C.sub.1 -C.sub.4 alkyl and R.sub.2 is unsubstituted phenyl or phenyl which is substituted by C.sub.1 -C.sub.4 alkyl, C.sub.1 -C.sub.4 alkoxy, C.sub.2 -C.sub.4 alkanoylamino or halogen.
