    Abstract: The quaternized heterocyclic monoazo dyes having as a diazo component a nitrogen containing cyclic group linked through the azo bridge to an imidazo heterocyclic coupler prepared by quaternization of the intermediate azo dye, are useful as dyes for acyclic, modacrylic and acid-modified polyester textile materials.
