Abstract
The specification discloses papers suitable for liquid electrophotographic printing ('LEP') and a method for making such papers. According to the method, a papermaking furnish containing cellulosic fibers is formed into a fibrous web on a papermaking machine and at least partially dried. The web is then treated with a sizing composition comprising starch, an acrylic acid polymer, an organic material having an HLB value of from about 2 to about 14 such as a polyglycerol ester, and water. The treated web is dried and calendered to a final desired caliper. Since the sizing composition is an aqueous mixture, it may be applied to the web on-line during production of the paper on the papermaking machine, thereby avoiding the expense and inconvenience of conventional off-line methods used to make existing LEP papers. The resulting paper exhibits at least 80% and preferably above 90% toner adhesion as measured by the tape pull tests used for the assessment of papers printed by LEP.
