Abstract
Disclosed are novel stable violet-blue to blue imidazolium azo compounds that have a simplified chromophore and high relative solubility in aqueous systems, and that are stable under the conditions of use and storage. The compounds are useful for dyeing fibers such as fabrics and hair, as fabric hueing agents, and as dyes for other keratinaceous materials. Also disclosed are laundry care compositions comprising the imidazolium azo compounds and methods of using the compositions.
