Abstract: Dyestuffs of the formula ##STR1## wherein R denotes hydrogen or alkyl,X denotes R, Cl or Br,m and p denotes 0 or 1,n denotes 2 to 4,A denotes oxygen or --NR-- andB denotes C.sub.1 -C.sub.8 -alkyl, alkenyl, cycloalkyl, aralkyl or aryl,are especially suitable for the dyeing of polyester-materials; they give deep yellow dyeings with good light fastness properties.

Abstract: Concentrated solutions of water-insoluble bis-acetoacetic acid-diphenylamides as coupling components; these solutions contain in addition to one or more of these coupling components water and sodium and/or potassium hydroxide and as aliphatic solvent one or more mono- or di- to hexa-ethyleneglycol monoalkyl ethers having lower alkyl radicals, and optionally ethyleneglycol, diethyleneglycol and/or propyleneglycol. The coupling components are contained in the solutions in a concentration of up to about 50% by weight without deteriorating the storage stability of the solutions. The solutions may be used for preparing water-insoluble azo dyestuffs on the fiber according to "ice-color" dyeing. On pouring into water containing a small amount of sodium hydroxide they give immediately ready-to-use impregnation baths.
