This invention relates to electrophotographic recording media that are suitable for use in high speed color copiers and printers. The media are composites comprising: a) a film substrate having a front surface coated with a toner-receptive layer and a back surface coated with a polymeric layer, and b) a paper backing that is attached to the back surface of the film substrate. The toner-receptive layer comprises a mixture of a hydrophobic toner-compatible polymer and hydrophilic toner-compatible polymer. The paper backing has a Sheffield Smoothness greater than 70 SU.

Electrophotographic media for use in high speed color copiers and printers

A color electrophotographic recording medium is disclosed that contains a polymeric base film substrate having coated on a side thereof a toner-receptive coating. The coating contains at least one low molecular weight toner-compatible resin segment and at least one high molecular weight thermoplastic resin segment, with the toner-compatible resin segment having a number average molecular weight in the range of about 1,000 g/mole to about 10,000 g/mole, and the thermoplastic resin segment having a number average molecular weight in the range of about 10,000 g/mole to about 500,000 g/mole. Optionally, the toner-receptive coating layer can also contain a polymeric particulate, an anti-static agent, and a surfactant.
