Abstract

Polyester fibres are dyed in yellow and orange-red color shades with good fastness to light and wet processing when dyestuffs of the formula <IMAGE> wherein K denotes the radical of a 5-amino-pyrazole coupling component which couples in the 4-position, R denotes an optionally substituted alkyl, cycloalkyl, aralkyl or aryl radical and the ring A can contain further non-ionic substitutents customary in dyestuff chemistry, are used.
