A method for producing a cyan liquid electrophotographic ink composition includes: dispersing in a first portion of carrier fluid cyan pigment particles and inorganic spacer particles, the inorganic spacer particles having a particle size (d50) of 0.1 μm or less, such that the inorganic spacer particles adhere to the cyan pigment particles; heating a polymer resin in a second portion of carrier fluid to dissolve the polymer resin; adding the dispersion of the cyan pigment particles having the inorganic spacer particles adhered thereto in the first portion of carrier fluid to the dissolved polymer resin in the second portion of carrier fluid; cooling the carrier fluid at a controlled rate to effect precipitation of the polymer resin from the carrier fluid such that a coating of the resin is formed on the cyan pigment particles having the inorganic spacer particles adhered thereto, thereby producing the cyan liquid electrophotographic ink composition.

A conductive ink able to be stretched without significant increase of the resistance includes a flexible resin, a plurality of plastic particles, and a conductive agent. The plastic particles and the conductive agent are mixed in the flexible resin. The conductive agent includes at least one conductive carbon material selected from a group consisting of conductive carbon black and carbon nanotube, and a mass ratio of the conductive carbon material in the conductive ink is in a range from 20% to 40%.

The present disclosure describes three-dimensional printing kits, systems for three-dimensional printing, and methods of three-dimensional printing. In one example, a three-dimensional printing kit can include a particulate build material and a binding agent. The particulate build material can include metal particles. The binding agent can include a polyhydroxy polyol and a water-dispersible blocked polyisocyanate having multiple blocked isocyanate groups. The blocked isocyanate groups can include a blocking group bonded to the carbon atom of the blocked isocyanate group through a labile bond breakable by heating to a deblocking temperature. Breaking the labile bond can produce a released blocking group reacted with hydrogen and an isocyanate group.

One example of a flexible printed article includes a non-conductive, graphene oxide membrane base substrate; and an electronic component positioned on the non-conductive, graphene oxide membrane base substrate. An example method for generating this example of the flexible printed article includes inkjet printing a conductive ink directly on the non-conductive graphene oxide membrane base substrate.
