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, 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.

Paper substrate having enhanced print density

This invention relates to a paper substrate containing high surface sizing and low internal sizing and having high dimensional stability, as well as methods of making and using the composition.

Paper substrates containing high surface sizing and low internal sizing and having high dimensional stability

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.

Paper substrate containing a wetting agent and having improved print mottle

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, and 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.

Paper substrate containing a wetting agent and having improved printability

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.

Papers for liquid electrophotographic printing and method for making same

The invention involves papers having either an internal starch or a size press applied starch and a boron-containing compound which is added in proportion to the starch and which is believed to interact with the starch to provide improved physical and mechanical properties in the paper. Method of forming the papers are also disclosed.

Papers having borate-based complexing and method of making same

The present invention relates to paper substrates containing either an internal starch or a size press applied starch and a boron-containing compound and having improved physical and mechanical properties, as well as methods of making and using the same.

A method of producing dimensionally stable paper and/or paperboard products by treating a hygroreactive cellulosic fiber matrix with a hydrophobic sizing agent solution; and drying the treated fibers using heat and/or pressure so that the hydrophobic sizing agent penetrates the fiber matrix making it hydrophobic.
