Abstract:
A printing medium comprising:(a) a substrate having at least one surface; and(b) a coating on the surface wherein the coating comprises:(1) binder comprising organic polymer, wherein poly(ethylene oxide) having a weight average molecular weight in the range of from 100,000 to 3,000,000 constitutes at least 20 percent by weight of the organic polymer of the binder and wherein the organic polymer of the binder constitutes from 20 to 80 percent by weight of the coating; and(2) finely divided substantially water-insoluble filler particles, of which at least 25 percent by weight are finely divided substantially water-insoluble nonfilm-forming thermoplastic organic polymer particles, wherein the filler particles have a maximum dimension of less than 500 nanometers, are distributed throughout the binder, and constitute from 20 to 80 percent by weight of the coating.
