ABSTRACT:
A coated xerographic photographic paper comprised of (1) a cellulosic substrate; (2) a first antistatic coating layer in contact with one surface of the substrate; (3) a second toner receiving coating on the top of the antistatic layer, and comprised of a mixture of a binder polymer, a toner spreading agent, a lightfastness inducing agent, a biocide, and a filler; and (4) a third traction controlling coating in contact with the back side of the substrate comprised of a mixture of a polymer with a glass transition temperature of from between about -50.degree. C. to about 50.degree. C., an antistatic agent, a lightfastness agent, a biocide and a pigment. The traction promoting third coating is also capable of receiving images from a xerographic copier/printer. The cellulosic substrate is comprised of alkaline sized and acid sized blends of hardwood kraft and softwood kraft fibers, which blends contain from about 10 percent to about 90 percent by weight of softwood and from about 90 to about 10 percent by weight of hardwood. The sizing value of the cellulosic substrate varies between 200 seconds to 1,100 seconds, the porosity varies from 50 to 300 mil/minute, and the thickness varies between 50 microns to 250 microns.
