Abstract

Procedure for preparing water soluble monoazo dyes corresponding to the formula ** (See formula) ** where A means a benzene radical, alk means an alkylene group, in particular a methylene or ethylene group, B means an aryl radical, R1, R2 and R3 mean alkyl groups, cycloalkyl groups or monocyclic aralkyl groups, where R1, R2 and R3 together with the nitrogen atom form a heterocyclic ring, Z means a group -CO-, -SO2- or imino and X means an anion, characterized by the fact that: a) the diazo compound of an amine of the formula is coupled ** (See formula) ** where R1, R2, R3, alk and A have the meaning set forth above, with a compound of the formula ** (See formula) ** where B and Z have the meaning set forth above, for which the components must be free of sulphonic acid groups, O well b) a dye of the general formula is reacted ** (See formula) ** where alk, A and B have the meaning stated above and Hal means a halogen atom, for example a chlorine atom or a bromine atom, with an amine, secondary or tertiary, O well c) a monoazo dye of the general formula is treated ** (See formula) ** where R1, R2, alk, A, B and Z have the meaning set forth above, with alkylating agents.
