Abstract
Procedure for obtaining azo dyes of difficult solubility, of formula: ** (See formula) ** where D means the remainder of a diazo component, K means the remainder of a coupling component containing as substituent a group of the formula ** (See formula) ** R1 is chosen from hydrogen and a group of the formula ** (See formula) ** R2 and R3, independently, are chosen from hydrogen, halogen, cyano, alkyl and alkoxy, being able to carry substituents, R4 is chosen from hydrogen, alkyl, alkoxy and phenyl, being able to carry substituents and n represents 1-2 and the molecule is free of groups sulfonic acid and carboxylic acid, characterized in that it comprises diazotizing an amine of formulas ** (See formula) ** wherein D and R1 are defined as above and couple the obtained diazo compound with a compound of formulas: h-K where K is defined as above.
