1. A reactive polyurethane dispersion, comprising a polymer strand comprising a polymer backbone having two ends terminating at a first capping unit and a second capping unit, wherein the polymer backbone comprises polymerized monomers including:

  • a reactive diol selected from an acrylate-containing diol, a methacrylate-containing diol, or combination thereof, anda diisocyanate;

    wherein the first capping unit is an acrylate-containing monoalcohol or a methacrylate-containing monoalcohol reacted with an isocyanate group of the diisocyanate; and

    wherein the second capping unit is 3-(cyclohexylamino)-1-propanesulfonic acid or 2-(cyclohexylamino)ethanesulfonic acid reacted with an isocyanate group of the diisocyanate.
