A paper comprised of a plastic supporting substrate, a binder layer comprised of polymers selected, for example, from the group consisting of (1) hydroxypropyl cellulose, (2) poly(viny1 alkyl ether), (3) vinyl pyrrolidone/vinyl acetate, (4) quaternized vinyl pyrrolidone/dialkylaminoethyl/methacrylate, (5) poly(viny1 pyrrolidone), (6) poly(ethy1ene imine), and mixtures thereof; and a pigment or pigments; and an ink receiving polymer layer. The aforementioned binder polymer layer can be present on both sides of the supporting substrate, and the ink receiving polymer layer may be present on both sides of the polymer layer. Specific examples of polymer binders include (1) hydroxypropyl cellulose, (2) poly(viny1 methyl ether), (3) vinyl pyrrolidone/vinyl acetate copolymer with a vinyl acetate content of from about 40 to about 70 percent by weight, (4) quaternized vinyl pyrrolidone/dimethylamino ethyllmethacrylate copolymer, (5) poly(viny1 pyrrolidone), (6) poly(ethy1ene imine), or mixtures thereof. Various suitable pigments can be selected including, for example, (1) titanium dioxide, (2) zinc oxide, (3) hydrated alumina, (4) barium sulfate, (5) calcium carbonate, (6) high brightness clays, (7) blends of calcium fluoride with silica, (8) blends of zinc sulfide and barium sulfate, and mixtures thereof.

Examples of the ink receiving polymer includes (1) poly(dially1 phthalate), (2) poly(dially1 isophthalate), (3) cellulose propionate, (4) ethylene-vinyl acetate- vinyl alcohol terpolymer with ethylene content of from about 20 to about 60 percent by weight, vinyl acetate content of from about 40 to about 20 percent by weight and vinyl alcohol content of from about 40 to about 20 percent by weight, (5) blends of chlorinated rubber with ethyIene/vinyl acetate copolymer, (6) blends of chlorinated rubber with poly(caprolactone), (7) blends of chlorinated rubber with poly(chloroprene), (8) blends of poly( ethylene) chlorinated with ethylenelvinyl acetate copolymer, (9) blends of poly(ethy1ene) chlorinated with poly(caprolactone), (10) blends of poly(ethy1ene) chlorinated with poly(chloroprene), (11) blends of poly(propy1ene) chlorinated with ethylenehinyl acetate, (12) blends of poly(propy1ene) chlorinated with poly(caprolactone), (13) blends of poly(propy1ene) chlorinated with poly(chloroprene), (14) poly...
