Title: REACTIVE POLYURETHANE DISPERSIONS
Abstract:
The present disclosure is drawn to a reactive polyurethane dispersion including a polymer strand having a polymer backbone that has two ends terminating at a first capping unit and a second capping unit. The polymer backbone can include polymerized monomers including a reactive diol and a blend of two or more diisocyanates. The reactive diol can be an acrylate-containing diol, a methacrylate-containing diol, or combination thereof. The first capping unit can be an acrylate-containing monoalcohol or methacrylate-containing monoalcohol reacted with an isocyanate group of the diisocyanates. The second capping unit can be an ionic stabilizing group. The polymer backbone can be devoid of ionic stabilizing groups.
