International Classification:

D21H 21/16
D21H 17/28
D21H 17/37

US Classification:

1621681, 162135, 162158, 1621641, 162175, 1062061, 1062152

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.

International Classification:

D21F 11/00

US Classification:

162158

Abstract:

The present invention relates to a sizing composition that, when applied to paper substrate, creates a substrate, preferably suitable for inkjet printing, having increased print density, enhanced print mottle, as well as print sharpness, low HST, and/or image dry time, the substrate preferably having high brightness and reduced color-to-color bleed as well. In addition, the present invention relates to a method of reducing the HST of a paper substrate by applying the sizing composition to at least one surface thereof. Further, the application relates to methods of making and using the sizing composition, as well as methods of making and using the paper containing the sizing composition.
