Abstract
Process for the preparation of monoazo dye pigments of the formula ** (See formula) ** in which R1, means a benzene radical, which does not show in the metal position to the azo group no carboxylic acid anilide group, R2 means a naphthalene radical, in which the azo, hydroxy and carboxylic acid amide groups are in position 1, 2, 3, R3 means a phenylene or diphenylene radical, in which the -NH- and -CO- groups are in para position to each other, and R4 means a hydrogen atom or an aryl radical free of benzylamino groups, characterized by that a) a carboxylic acid halide of the formula is condensed ** (See formula) ** with an amine of the formula H2n-R2-CONH-R4 O b) a carboxylic acid halide of the formula is condensed ** (See formula) ** with ammonia or an arylamine free of benzoylamino groups, O c) copying the diazo compound of an aminobenzene, which does not show in the meta position to the amino group any carboxylic acid amide group, with a naphthol of the formula (see formula) (Machine-translation by Google Translate, not legally binding)
