Abstract

Procedure for obtaining azo compounds, of difficult solubility in water, of the formula: **(See formula)** where A represents the remainder of a diazo component, B represents phenylene or naphthylene, optionally bearing substituents, means hydrogen or alkyl or aryl, optionally bearing substituents, R2 and R3'independent of each other, meaning cyano or a group of the formula -CO-OR4 or -CO-NR5R'5 or together a group of the formula -CO-NR5-CO-, R4 signifies alkyl or aryl, optionally bearing substituents and R5 and R5'independent of each other, signify hydrogen or alkyl or aryl, optionally bearing substituents, the molecule being however free of carbonic acid or sulfonic acid groups, characterized in that an amine of formula A - NH2 diazotized and coupled with a compound of the formula (see formula) (Machine-translation by Google Translate, not legally binding)
