Abstract

Procedure for the preparation of new water-soluble monoazo dyes of the general formula (1) **(See formula)** in which K means the radical of a coupling component of the series benzene, naphthalene, acetoacetic acid arylamide, pyrazolone or dihydroxyquinoline, which as aqueous solubilizing groups may contain sulfonic acid or carboxylic acid groups, R means an atom hydrogen or an alcohol or aryl group, X means a grouping of the formula (2) **(See formula)** or of the formula (3) **(See formula)** in which R'means a hydrogen atom or an alcohol group, R''means a hydrogen atom or an alcohol or phenyl group, Y and Y' means fluorine or chlorine atoms, and n means the numbers 0 or 1, characterized in that an amine of the general formula is diazotized **(See formula)** wherein E is a hydrogen atom or has the aforementioned meaning of X, and why the obtained diazonium compound is coupled with an azo component of the general formula **(See formula)** where E, K, R and n have the aforementioned meanings, and the monoazo compound thus obtained of the formula **(See formula)** Where E stands for a hydrogen atom and K, R and n have the aforementioned meanings, it is reacted with an acid halide of the general formula or of the general formula (8) in which R', R'', Y and Y' have the aforementioned meanings and Z represents a chlorine or bromine atom, in purely aqueous, aqueous-organic and organic media in the presence of acid fixing agents, at temperatures between 0 and 80ºC and at pH values between 4 and 10.
