The present disclosure is drawn to coated print media, methods of making coated print media, and methods of printing. In one example, a coated print medium can include a substrate, a base coating layer on the substrate, and a top coating layer on the base coating layer. The base coating layer can include an inorganic pigment, a binder, and a fixing agent. The top coating layer can include polyvinyl alcohol and polymer nanobeads having a gloss transition temperature from 70° C. to 350° C. The polyvinyl alcohol and polymer nanobeads can be included at from 50 wt % to 100 wt % by dry weight of the top coating layer.

The present disclosure is drawn to printable media. A printable medium includes a substrate having a first side and a second side. An ink-receiving layer is positioned on the first side of the substrate. The ink-receiving layer includes a colloidal sol. An ink-penetrable layer is positioned on the ink-receiving layer. The ink-penetrable layer includes a binder and polymer particles having a glass transition temperature from 80° C. to 150° C. A repositionable adhesive layer is positioned on the second side of the substrate. A release liner is removably positioned on the repositionable adhesive layer. A friction control layer is positioned on the release liner, where the friction control layer includes a slip aid.

An inkjet recording medium includes a substrate having a resin layer, a bonding layer disposed on the resin layer, and an ink-receiving layer disposed on the bonding layer. The surface of the inkjet recording medium on the ink-receiving layer side of the inkjet recording medium has a 20° glossiness of 13.0 or more. The bonding layer contains an ultraviolet inhibitor at a content of 5.0% by mass or more and 35.0% by mass or less based on the total mass of the bonding layer.

Dispersible record materials or media include a water-soluble or water-dispersible paper substrate, a printable layer carried by the substrate, and a base coat between the substrate and the printable layer. The printable layer may be a thermally responsive layer, e.g. containing a leuco dye and an acidic color developer, or an inkjet receptive layer. The binder material used in the base coat, and the base coat itself, are non-water-soluble, but nevertheless tailored in such a way that the record material as a whole is water-dispersible, i.e., it breaks apart under the influence of water with minimal agitation. The binder material of the base coat is preferably a non-resinous binder, a particulate binder, and/or a binder derived from a dispersion, such as latex. Use of such a binder material in a carefully selected concentration, with other elements, provides a base coat that allows for high quality images to be thermally printed at high print speeds on the thermally responsive layer.

A method of forming a digital print on a surface by applying powder of dry ink including colourants on the surface, bonding a part of the dry ink powder to the surface by a digital heating print head such that the digital print is formed by the bonded dry ink colourants and removing non-bonded dry ink from the surface.

Provided is an inkjet recording medium for an organic semiconductor device including a base material, an electrode, and ink receiving layer in this order, wherein the ink receiving layer has an ink penetration prevention area on an electrode side that prevents ink which permeates from a surface far from the electrode toward the electrode from reaching the electrode.
