Abstract

Process for the preparation of monoazo dye pigments, of the formula ** (See formula) ** in which R1 means a benzene radical in which the group -CONH is in the meta position with respect to the azo group R2 means a naphthalene radical in which the azo, hydroxyl and carbonamide groups are in the 1,2,3 position R 3 means a phenylene or diphenylenic radical; Y R4 and R5 mean hydrogen atoms or aryl radicals lacking benzoylamines, characterized by: a) a carboxylic acid halide of the formula ** (See formula) ** with an amine of the formula H2N-R3-CONH-R4 b) condensing a carboxylic acid halide of the formula ** (See formula) ** where And it means a halogen atom or the radical -NH-R5, with ammonia or with an arylamine lacking benzoyl amine groups, O well c) copying the diazo compound of an amine of the formula H2N-R1-CONH-R5 with a naphthene of the formula (see formula) (Machine-translation by Google Translate, not legally binding)
