Zusammenfassung:	Ink jet media having low coefficients of friction to enable efficient sheet feeding performance and which are compatible with modern inks. In a preferred embodiment, ink jet media include a substrate, a coating including a binder, a pigment, and a low friction substance. The low friction substance, in an emulsified form, is selected from the group consisting of waxes, simple organic polymers, silicone polymers and fluoropolymers. The binder is selected from the group consisting of polyvinylversatate, polyethelene, polyvinyl alcohol, polyvinylpyrrolidone and polyvinylacetate and it comprises between about 5% and about 30%, by weight, of the coating. Preferably, the pigment is alumina or silica. In addition, polyterfluoroethylene latex is utilized as a slip aid. A method of preparing ink jet media includes the steps of providing a substrate and a coating including a binder, as described above. The binder is mixed with a low friction substance, in an emulsified form, selected from the group consisting of waxes, simple organic polymers, silicone polymers and fluoropolymers. The mixture is applied to the substrate and the substrate is dried.
