A multifunctional identification label comprises a paper substrate formed from a cellulose furnish including 1 to 2.5 percent of a wet strength resin and a rosin size. A front side of the substrate is machine glazed, coated with a print receptive coating, and printed with a bar code. The back side of the substrate has a coating comprising one or more pigments selected from the group of clay, magadite and mixtures thereof, a binder, and 1 to 2.5 parts by dry weight of pigment of a salt. A conductive ink antenna is printed on the back side coating. A RFID chip is secured to the back side of the coated substrate and electrically connected to the antenna. Embodiments of the invention include a pressure sensitive adhesive label including RFID and bar code identification, a ticket adapted for printing on both sides incorporating RFID identification, and an RFID insert.

A high quality ink jet recording medium is formed of a dimensionally stable absorbent paper base sheet and a coating that is primarily a reaction product of polyvinyl alcohol and boric acid. The reaction product has molecule bonds that are principally polyvinyl alcohol-boric acid-polyvinyl alcohol bonds which, when applied to the substrate, form a three-dimensional sieve or screen-like coating facilitating penetration to the absorbent base-sheet of ink carrier vehicle and holding out on the sieve or screen the ink pigments and colorants. The coating facilitates manufacture of a high quality recording medium of exceptionally low cost, ideally suited for high-speed multicolor ink jet printing in continuous web form. Methods of making the coating and the medium are disclosed.
