Abstract

Procedure for obtaining water-soluble monoazo dyes of the formula: **(See formula)** wherein R1 represents hydroxyl, amino, alkylamino, dialkylamino, arylamino or sulfate alkylamino; R2 represents hydrogen, sulfo or carboxy; R3 represents hydrogen, alkyl, sulfo or carboxy; R4 represents hydrogen, halogen, hydroxy, aryl, alkyl or alkoxy; And R5 represents hydrogen, alkyl, acyl or arylsulfonyl, with the group -OR5 in position 2 or 4 with respect to the azo group and the substituents R1, R2 and R3 being chosen so that the total number of sulfo, sulfate and carboxy groups is two, of which not more than one is a carboxy group; characterized in that it comprises diazotizing an amine of formula; **(See formula)** and coupling the resulting diazo compound with a phenol of the formula: **(See formula)** wherein R1, R2, R3 and R4 are defined as above and, where necessary, the hydroxyl group is converted to an alkoxy, acyloxy or arylsulfonyloxy group.
