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.

The roll properties of tissue sheets are improved either by imparting cross-machine direction dominant bar-like protrusions to the air side of the tissue by using specially woven transfer fabrics and / or by offsetting recurring surface features of the sheet relative to the surface features of adjacent sheets within the roll, such as by providing a throughdryer fabric with an offset seam. Both techniques provide the resulting tissue sheets with improved capabilities for providing an improved combination of roll bulk and roll firmness.

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.

Sanitary tissue products employing 3D patterned fibrous structure plies having a surface comprising a novel three-dimensional (3D) pattern such that the 3D patterned fibrous structures and / or sanitary tissue products employing the fibrous structures exhibit novel cushiness as evidenced by compressibility of the fibrous structures and / or sanitary tissue products, novel flexibility as evidenced by plate stiffness of the fibrous structures and / or sanitary tissue products, and / or surface smoothness as evidenced by slip stick coefficient of friction of the fibrous structures and / or sanitary tissue products, and methods for making same, are provided.

The invention relates to an apparatus for the application of coatings to surfaces of substrates in the form of paper, paperboard, or plastics foils, preferably for the finishing of print products. The apparatus encompasses a coating unit for the application of coating material in fluid form to the substrate surface, and equipment for smoothing of the film while it is still fluid after it has been applied by means of the coating unit to the substrate surface, where the equipment encompasses equipment for generating a gas stream orientated onto the substrate surface coated with the film, where the gas stream smooths the film with at least partial elimination of undesired structures in the film surface, e.g. depressions, elevations and craters, prior to the hardening of the coating material.

This invention provides a gloss-coated electrophotographic paper with superior runnability and print quality in colour and monochrome copiers and printers. The coated paper product comprises a paper substrate coated on at least one side with a pigmented coating. The pigment coating consists of a mixture of at least three different pigments and a binder. The coating may further include a lubricant. Optionally, the coating formulation may contain an optical brightening agent, a defoamer and a thickener. In addition, the gloss coated electrophotographic paper of this invention provides a superior toner adhesion in colour and monochrome electrophotographic imaging applications.
