Abstract

Procedure for the preparation of the disazo pigments of the formula ** (See formula) ** where A stands for an alkylene, arylene or heterocyclic radical; Z means a hydrogen or halogen atom or an alkyl, alkoxy, alkoxycarbonyl or aryloxy group; R stands for an alkyl, cycloalkyl, aralkyl, aryl or hethocyclic radical; and B means an aromatic radical, characterized by coupling a diazo or diazoamine compound of an amine of the formula ** (See formula) ** where A, R and Z have the meaning already stated, with a bis-acetoacetyl-arylenediamine of the formula CH3COCH2CONH-B-NHCOCH2COCH3 where B has the meaning already stated, in the molar ratio of 2: 1.
