Abstract

Procedure for preparing sulfolic group-free azole dyes of the formula ** (See formula) ** where D signifies the residue of a diazo component, A signifies an alkylene residue, R1, R2 and R3 signify alkyl, cycloalkyl, aralkyl or aryl, R4 signifies hydrogen, alkyl, cycloalkyl, aralkyl or aryl or, together with R3, including the nitrogen atom, can form a 5- or 6-membered heterocycle and Q signifies hydrogen, a cyano group, a carbonamide group, optionally substituted, or a carboxylic acid ester group; characterized by diazotized amines of the formula D - NH2 where D has the meaning indicated in claim 1, they are coupled with coupling components of formula ** (See formula) ** where R1-R4, A and Q have the meaning indicated above.
