Abstract

A process for the production of monoazo dispersion dyes of formula I **(See formula)** wherein R1 signifies an unsubstituted or substituted phenyl or aminocarbonyl alkyl radical or a C1-C4 alkoxy or unsubstituted (C1-C4) alkoxy-, carbonyl radical, R2 means an unsubstituted (C1-C4) alkoxy- or carbonyl radical or a cyano group, with the requirement that such be cyano only when at least one of R1 and R3 has a different meaning than methyl, R3 means hydrogen or a C1-C4 alkyl, cycloalkyl or optionally substituted phenyl radical, and K means the radical of a coupling component selected from the series of aminobenzene, aminonaphthalene, pyrazolone-5, 5-aminopyrazole, pyridone, pyrimidone, tetrahydroquinoline, coumarin or pyrrole, or from the aliphatic series containing an activated methylene group, characterized in that a diazation product of an amine of formula II is reacted. **(See formula)** wherein R1, R2 and R3 are as defined above, with a compound of formula H-K, where K is as defined above.
