Abstract: A photo curable ink composition includes a photo-reactive binder, a water soluble polymeric sensitizer, a water soluble photoinitiator, a colorant, and a balance of water. The water soluble polymeric sensitizer includes a functionalized anthrone moiety, a polyether chain, and an amide linkage or an ether linkage attaching one end of the polyether chain to the functionalized anthrone moiety. The water soluble photoinitiator having a formula (I) of: wherein n is any integer from 1 to 5 and M is a metal with a valence from 1 to 5.

Abstract: The present disclosure is drawn to printing systems. In one example, a printing system can include an inkjet print head and a plasma generator. The inkjet print head can be used to form a printed image on a media substrate. The plasma generator can be positioned with respect to the inkjet print head to treat the printed image after application to the media substrate.

Abstract: In example implementations, a system is provided. The system includes at least one fluid ejection apparatus, a heater and an energy source. The at least one fluid ejection apparatus dispenses a de-contented fluid onto a substrate during conveyance of the substrate. The heater is arranged after the at least one fluid ejection apparatus along a substrate conveying path. The heater removes a liquid from the de-contented fluid on the substrate such that the particles of the de-contented fluid remain on the substrate. The energy source is arranged after the heater along the substrate conveying path. The energy source applies energy to the substrate during the conveyance of the substrate to heat the substrate to a temperature that is approximately a melting temperature of the substrate to fuse the particles on the substrate to the substrate.

Abstract: An example of a liquid bonding agent, for a liquid ink including a wax emulsion in an amount less than 1% actives, includes a calcium salt, the wax emulsion, an acetylenic surfactant, a glycol, and a balance of water. The wax emulsion is present in the liquid bonding agent in an amount ranging from greater than 0% actives to about 2% actives. The liquid bonding agent is to be digitally printed with a thermal inkjet printhead on a substrate under the liquid ink.

Abstract: The present invention is drawn to a method of treating silica in an aqueous environment. The method can comprise steps of dispersing silica particulates in an aqueous environment to form an aqueous dispersion; reversing the net charge of a surface of the silica particulates from negative to positive using a surface activating agent, thereby forming surface-activated silica particulates dispersed in the water; and contacting the surface-activated silica particulates with organosilane reagents to form reagent-modified and surface-activated silica particulates.
