Abstract

Procedure for the preparation of disazo pigments of the formula **(See formula)** in which A and B signify arylene radicals; R1 and R2 signify benzoyl radicals; and X means an alkyl group with at least 3 carbon atoms; characterized by: a) condensing in the molar ratio of 1: 2 a dihalide of a dicarboxylic acid of the formula **(See formula)** with an amine of the formula **(See formula)** or, in a variant of it, b) coupling, in the molar ratio of 2: 1, a diazo or diazoamine compound of an amine generically belonging to the same group as that indicated in variant a) and of the formula **(See formula)** with a diacetoacetylarylene diamine generically belonging to the same diacetylated group as the dicarboxylic dihalide, also indicated in variant a) and of the formula **(See formula)** in all of which the substituents A, B, R1, R2 and X have the same meaning as in the general formula of the pigments.
