Abstract:
Rinsable dyes with improved fugitivity are formulated by attaching dyestuff compounds with amine-capped sulfonic solubilizing groups to commercially available ethoxylated aniline, so that the surfactant effect of the ethoxylated aniline counteracts the substantivity of the dyestuff compound, while the neutralization of the sulfonic solubilizing groups reduces substantivity.
