    Abstract: Monoazo dyestuffs which in the form of the free acid correspond to the formula

    WHEREIN R1 is alkyl or aryl; R2 is hydrogen or alkyl; R3 is hydrogen, halogen or alkyl; R4 is hydrogen, halogen, alkyl, alkoxy, or nitrile; p or m are 0 or 1 with the sum of the two being 1 or 2; and n is 1 or 2; and A may contain further substituents free of sulfo or sulfato, and their use for the dyeing of natural and synthetic fibre materials, especially for dyeing polyamide fibres. They give level dyeings of good yield with very good fastness to light. They are even absorbed well on polyamide fibres from a neutral to weak acid dye bath. By polyamide fibres there are here especially understood those of synthetic polyamides such as Epsilon -polycaprolactam or condensation products of adipic acid and hexamethylenediamine.

    Abstract: Disazo dyestuffs which in the form of the free acid correspond to the formula

    IN WHICH R1 is aryl, a C1-C4-aliphatic radical or dialkylamino with 1-6 carbon atoms in the alkyl radical; R2 is chlorine, bromine, alkoxy, or alkyl; R3 and R4 are hydrogen, chlorine, bromine, alkoxy, or alkyl; R5 is alkyl or aryl; R6 is hydrogen, alkyl, or alkyl substituted by cyano, carbonamide or carboxyl; R7 is a substituent, such as alkyl, alkoxy, halogen, nitro, sulfo, or cyano; B is a 1,4-phenylene or 1,4-napthylene radical; M IS A NUMBER 0-2; AND N IS A NUMBER 0-2; AND THEIR USE FOR THE DYEING AND PRINTING OF NATURAL AND SYNTHETIC FIBER MATERIALS CONTAINING AMIDE GROUPS, FOR EXAMPLE THOSE OF WOOL, SILK AND POLYAMIDE, SUCH AS POLY- Epsilon CAPROLACTUM OR THE REACTION PRODUCT OF HEXAMETHYLENE-DIAMINE WITH ADIPIC ACID, ARE DISCLOSED. The dyeings obtained, especially those on polyamide materials, are distinguished by good fastness properties, especially by good fastness to wet porcessing and good fastness to light.
