摘要

A coated cellulosic web product and coating composition which provides enhanced toner adhesion for documents printed using noncontact printing devices such as laser printers is provided. The toner adhesion enhancing coated cellulosic product includes a cellulosic web having first and second major surfaces with at least one of the major surfaces having coated thereon a polymeric toner adhesion-enhancing composition comprising a generally transparent copolymer of styrene and acrylic acid having a glass transition temperature of between about -16 and 22 degrees C and from about 1 to about 5% by weight zinc as a cross-linking agent for said copolymer. The web may be either continuous or in sheet form. The toner adhesion-enhancing composition may also optionally include a coloring agent and a plasticizing agent.
