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.

Toner adhesion enhancing coating and coated paper

A security coating for business documents printed using noncontact as well as impact printing devices is provided which enhances the adhesion of toner particles and/or ink to a document substrate. Other security features may be also be added to the coating to provide a dual-function coating which also provides visible evidence of tampering, either by the application of solvents, mechanical abrasion, heat, or when pressure is applied.

Business document having security features

A confidential information bearing article comprising a cover sheet adhered to a base sheet is provided which is capable of providing hidden confidential information to a recipient. Through the use of camouflage, obscuring, and opacifying and reflectivity increasing coatings, the paper used for the mailer becomes effectively opaque, and information printed on the inside of the article is substantially unreadable from the outside. The article includes an adhesive for securing the base sheet and cover sheet and perforations along the edges to assist the recipient in opening the article.

Confidential information bearing article

A protective coating composition for protection of thermal images on thermal paper is provided. A mixture of oligomers, monomers, and a photocatalyst are blended together, coated onto thermal paper and then cured by ultraviolet radiation. The coating provides protection to images subsequently printed on the paper by providing resistance to solvents, abrasion and fading due to exposure to light.
