A color sampling display product is provided that includes a radiation-curable water-based coating composition applied to a substrate, and shows mechanical integrity and aesthetic appeal.

A composition of matter wherein the composition comprises a siliceous substrate having silanols on the surface and a polymer selected from the group consisting essentially of a water soluble polymer, a water soluble copolymer, an alcohol soluble polymer, an alcohol soluble copolymer, and combinations of such polymers, wherein the polymer is chemically bonded to the siliceous substrate by a silane linking material having the general formula

O.sub.3/2SiQY

that is derived from an alkoxy-functional silane having the general formula

(RO).sub.3SiQX

and processes for preparing the crosslinked polymer that is chemically bonded to the surface of the siliceous substrate.

The invention relates to a packaging board comprising a fibrous base and one or more polymer coating layers on one or both sides of the fibrous base. According to the invention the fibrous base contains the combination of an alkyl ketene dimer size, stearic acid anhydride, a wet-strength size and an aluminium compound, which give the board resistance to aggressive liquids as well as thermal treatment, particularly an improved resistance to raw edge penetration in such circumstances. The invention further relates to containers and packages made of the board, for instance disposable drinking cups, dairy product cartons and auto-clave packages, as well as use of the board for such purposes.

A composition for treating cellulosic materials is provided. The composition comprises a dispersion of micronized additives. The dispersion comprises additive particles with diameters in the range of 0.001 to 25 microns. Also provided is a method for the application of the additive-containing composition to wood, as well as wood products which have been treated with the composition.

A barrier coating composition may include an alcohol-based binder; and an inorganic particulate, wherein mineral oil transmission through the barrier coating is such that the reduction in measured IR intensity at 2920 cm.sup.1 is less than 1.0%, as determined by ATR-FTIR spectroscopy.

A wet coating composition useful for coating a cellulosic fiber-based substrate is provided. The composition includes two aqueous emulsions. The first emulsion includes an oxidized paraffin/polyethylene wax and the second emulsion includes an ethylene/acrylic acid copolymer wax, ethylene/acrylic amide copolymer wax, ethylene/acrylic acid/acrylic amide copolymer wax or a mixture thereof. The oxidized paraffin/polyethylene wax has a surface energy less than or equal to 25 mN/m being substantially dispersive energy. The wet coating composition when dried forms a coating having a surface energy ranging from 20 to 60 mN/m being the sum of dispersive and polar energies. A process for treating a cellulosic fiber-based substrate with the wet coating composition, a substrate coated and articles including the coated substrate are also described. The process involves a heating step to allow migration of the coating towards a core of the cellulosic fiber-based substrate.

A primer-less coating composition for facestock comprises: a binder being a water-dispersible polymer; an ethylenically unsaturated compound which is aqueous-dispersible and miscible with or bonded to said water-dispersible polymer, wherein said ethylenically unsaturated compound is able to form a covalent bond with an ink; and a crosslinker, wherein said crosslinker is suitable for binding the coating to the facestock. The coating composition may be applied to a substrate to form a printable film. A printed film in accordance with the invention may be used in a label, for example for use on a container such as a bottle.

A non-transparent paper is described for non-transparent art or graphic design sketches, which prevents seepage of the inks, it accepts any type of gel, water-based, solvent-based, oil-based or mixed inks and solid materials for sketching and drawing, as well as fixatives for the solid materials. This paper consists of a lamination of at least two sheets of uncoated bond paper, inserting at least one intermediate layer of pigmented opacifying emulsion between both sheets, applied between the layers of paper to prevent transparency and the seepage of inks from one face of the lamination to the other. This layer of emulsion contains at least one opacifying pigment, at least one adhesive, agents to control viscosity and surface tension and other components. The outside layers of paper have a drying capacity which fixes the materials used for the sketching and prevent outlines made on one face passing to the adjacent sheets of paper, and also has a texture suitable for receiving any dry material for drawing or sketching.
