A toner composite material includes toner particles that include a sulfonated polyester and a wax and metal nanoparticles disposed on the surface of the toner particles. A method includes providing such toner composite materials, fusing the material to a substrate and covalently linking a ligand to the surface of the silver nanoparticles via a thiol, carboxylate, or amine functional group. Detection strips include a substrate and such toner composite materials fused on the substrate.

Sulfonated polyester-metal nanoparticle composite toner for colorimetric sensing applications

An aqueous ink composition including water; an optional co-solvent; an optional colorant; and a composite nanoparticle comprising a core and a shell; wherein the core comprises a styrene/acrylate polymer core resin, optionally comprising a metal; and wherein the shell comprises a metal. An aqueous ink composition including water; an optional co-solvent; an optional colorant; and an ionic polymer-metal composite; wherein the ionic-polymer metal composite nanoparticle acts as a reservoir for the delivery of metal ions for anti-bacterial effect, antifungal effect, antiviral biocide effect, or a combination thereof. A process comprising incorporating an aqueous ink into an ink jet printing apparatus; ejecting droplets of ink in an imagewise pattern onto an intermediate transfer member or directly onto a final image receiving substrate; optionally, heating the image; and optionally, when an intermediate transfer member is used, transferring the ink in the imagewise pattern from the intermediate transfer member to a final substrate.

Anti-bacterial aqueous ink compositions comprising metal ion composite ionomer resins

Toner particles contain a core-shell resin particle containing at least one (sulfo) polyester containing a metal on nanoparticle, and a shell containing a metal ion nanoparticle.

Antimicrobial sulfonated polyester resin

Ionomer composite resins and core/shell nanoparticles are described. The ionomer resin contains a metal ion. The metal can be in the core, shell or both.
