The present disclosure is drawn to a base paper substrate that is cellulose-based and an ink-receiving layer on the base paper substrate. The ink-receiving layer, for example, includes a metal salt, inorganic particulates, a polymeric binder, and an emulsifier including a hydroxylated saturated hydrocarbon block including from 6 to 24 carbon atoms and a hydroxyl group and further includes a polyalkylene oxide block including form 10 to 35 polyalkylene oxide units selected from polyethylene oxide, polypropylene oxide, or a combination thereof.

The present disclosure relates to a binding agent for printing a 3D green body object. The binding agent includes from about 0.3 wt % to about 3 wt % multi-functional carboxylic acid having a weight average molecular weight range from about 100 MW to about 1,000 MW, from about 2 wt % to about 20 wt % a (meth)acrylic latex binder, from about 10 wt % to about 40 wt % solvent package including from about 3 wt % to about 40 wt % of a coalescing solvent, and from about 40 wt % to about 88 wt % water. The weight percentage ranges are based on total content of the binding agent.

An emulsion ink includes a carrier fluid, pigment particles, and a liquid resin. The carrier fluid is a dielectric, non-aqueous carrier fluid. The pigment particles are within the carrier fluid. The liquid resin is in a dispersed phase within the carrier fluid. The liquid resin is to be polymerized after the ink is applied to a substrate.
