  • Rinsable dyes and methods for their preparation
    Patent number: 8802829
    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.
    Type: Grant
    Filed: May 16, 2012
    Date of Patent: August 12, 2014
    Assignee: Spectra Colors Corp.
