Total heat exchange element paper having excellent moisture resistance and gas barrier properties, comprising a substrate sheet and a moisture absorbent and colloidal silica both of which are adhered to the substrate sheet, wherein the substrate sheet contains natural pulp which has been beaten to a freeness specified in JIS P 8121-1:2012 of not lower than 80° SR and the colloidal silica is cationic colloidal silica.

Novel coatings disclosed herein can be used to mitigate dust adhesion. In one embodiment, a method of making a dust repellant coating includes combining a titanium dioxide sol with colloidal silica to form a mixture. The method also includes adding solvent to the mixture, stirring the mixture for about an hour, and filtering the mixture into a solution of titanium dioxide and silica dioxide.

The present invention relates generally to the field of polymer dispersion coated, paper-based flexible packaging materials. In particular, the present invention relates to improving the barrier properties of polymer dispersion coated 5 paper-based flexible packaging materials. Embodiments of the present invention relate to a process for improving the barrier properties of polymer dispersion coated paper-based flexible packaging materials comprising the step of applying an Al2O3 coating to at least one surface of the dispersion coated paper-based flexible packaging materials, for example by using atomic layer deposition; and an Al2O3-coated paper material 10 obtainable by such a process.

Provided are a printing sheet having a coating layer for receiving ink on at least one surface of a substrate and having excellent printability, excellent adhesiveness between the substrate and the coating layer, and excellent antistatic performance and thus being less likely to cause troubles such as paper jams during printing, and further having excellent properties such as water resistance and weather resistance in a printing sheet; and a method for producing the same. The printing sheet includes a coating layer formed by blending (meth)acrylic ester-based resin particles in a proportion of 1% by mass or more and 10% by mass or less and clay in a proportion of 50% by mass or more and 70% by mass or less in a continuous phase made of an acrylic polymer.

The invention relates to a paper coating slip composition comprising a copolymer of thickening acrylic acid, a mineral material in the form of particles, a binding agent, and water. The invention also relates to the use of said composition for the production of paper or cardboard, improving the water retention of the paper coating slip.

A cellulosic structure including a cellulosic board substrate, a metal oxide layer positioned over the cellulosic board substrate, and a tie layer between the cellulosic board substrate and the metal oxide layer.

The invention relates to a titanium dioxide particle with high opacity and UV-greying resistance comprising two silica coats and at least one alumina coat, to a method for the obtaining the same, and to the use of said particle in a method for obtaining a decorative paper laminate or a décor foil. The present invention further pertains a decorative paper laminate or a décor foil containing said coated titanium dioxide particle.

The invention relates to a wrapper paper for smoking articles, comprising cellulose fibres loaded with calcium carbonate particles, wherein the mass of the cellulose fibres loaded with calcium carbonate particles is at least 1% of the mass of the wrapper paper, and the calcium carbonate particles in the cellulose fibres loaded with calcium carbonate particles make up at least 5% and no more than 80% of the mass of the cellulose fibres loaded with calcium carbonate particles.

The present invention concerns a process for preparing self-binding pigment particles from an aqueous suspension of calcium carbonate containing material, wherein an anionic binder and at least one cationic polymer are mixed with the suspension.

The present invention relates to a process for the preparation of precipitated calcium carbonate allowing for a more sustainable and cost-efficient use of milk of lime. The obtainable products show good optical properties as well as fine particle size distributions.
