Abstract: The present disclosure is drawn to reactive polyurethane dispersions. In one example, a reactive polyurethane dispersion can include 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 diisocyanate. The reactive diol can be an acrylate-containing diol, a methacrylate-containing diol, an acrylamide-containing diol, a methacrylamide-containing diol, or combination thereof. The first capping unit can be an acrylamide-containing monoalcohol or methacrylamide-containing monoalcohol reacted with an isocyanate group of the diisocyanate. The second capping unit can be an ionic stabilizing group.
