Abstract: An inkjet ink includes a polyurethane binder particle including at least two polyurethane polymers; a pigment; and an aqueous vehicle. A first of the at least two polyurethane polymers has a first backbone chain formed from a first diisocyanate, a first hydrophobic graft diol, a first polycarbonate based diol, and a sulfonated diamine. A second of the at least two polyurethane polymer has a second backbone chain formed from a second diisocyanate, a second hydrophobic graft diol, and a second polycarbonate based diol, and includes a mono-amino substituted sulfonic acid as its capping moiety.

Abstract: The present disclosure is drawn to polymeric photoactive agent compositions. The polymeric photoactive agent composition can include a polymeric photoactive agent including a xanthone analog modified with a polyether chain connecting to the xanthone analog through an ether linkage. The polymeric photoactive agent can be present in a reaction product mixture with either i) a xanthone analog modified with a hydroxyl group, or ii) a carbonate base.

Abstract: An example of a thermal inkjet fluid composition includes a water soluble photoacid generator having substantially no absorbance at a radiation wavelength ranging from about 360 nm to about 410 nm, a water soluble polymeric sensitizer having absorption at the radiation wavelength ranging from about 360 nm to about 410 nm, a polymeric binder, and a balance of water. The water soluble polymeric sensitizer includes a functionalized aromatic chromophore moiety, a polyether chain, and an amide linkage or an ether linkage attaching one end of the polyether chain to the functionalized aromatic chromophore moiety.

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 diisocyanate. The reactive diol can be an acrylate-containing diol, a methacrylate-containing diol, a styrene-containing diol, or combination thereof. The first capping unit can be a styrene-containing monoalcohol reacted with an isocyanate group of the diisocyanate. The second capping unit can be an ionic stabilizing group.
