ABSTRACT:
The present invention provides a coated cellulosic web product and coating composition which provides enhanced toner adhesion for documents printed using noncontact printing devices such as ion deposition printers. The toner adhesion enhancing coated cellulosic product and composition comprises a cellulosic web having first and second major surfaces with at least one of the major surfaces having coated thereon a layer of a polymeric toner receptor. The polymeric toner receptor layer preferably also includes an electrolyte to adjust the electrical conductivity of the cellulosic web to have a volume resistivity of between about 5.0.times.10.sup.9 and 1.0.times.10.sup.12 ohm cm. The toner receptor layer is applied at a coating weight of from about 0.3 to about 2.0 lb/ream. The invention provides printed documents which can withstand the normal automated handling operations commonly encountered by business documents such as checks, other MICR coded documents, bar coded documents, and the like without the flaking off or removal of the toner from the document. Further, documents printed on substrates utilizing the coating composition of the present invention have been found to have increased resistance to intentional defacement or alteration of printed information.
