Abstract
Disclosed is a recording paper which comprises (a) a cellulosic base sheet having a first surface and a second surface opposite the first surface, said base sheet having a dielectric constant of at least about 1.5 under conditions of about 50 percent relative humidity and at about 23° C., said base sheet having a dielectric constant of no more than about 10 under conditions of about 50 percent relative humidity and at about 23° C., said base sheet having, under conditions of about 50 percent relative humidity and at about 23° C., a surface resistivity of at least about 1×10 ohms per square, said base sheet having, under conditions of about 50 percent relative humidity and at about 23° C., a surface resistivity of no more than about 1×10 ohms per square; (b) on the first surface of the base sheet an image receiving coating comprising a monomeric or polymeric material, said image receiving coating having a glass transition temperature of at least about 55° C., said image receiving coating having a surface resistivity that is within about 10 percent of the surface resistivity of the base sheet, said image receiving coating having a gloss value of at least about 50 GU; and (c) on the second surface of the base sheet a back coating comprising a monomeric or polymeric material, said back coating having a surface resistivity that is within about 10 percent of the surface resistivity of the base sheet.
