A layer structure includes a substrate, a clay coating applied to the substrate, and a high performance coating applied to the clay coating, the high performance coating is configured to be thermally stable when subject to heating in either of a conventional oven and a microwave oven.

A coated paperboard having a natural appearance is disclosed which includes a barrier coating containing substantially no fluorochemical or wax, exhibiting good resistance to oil, grease, and moisture and having no tendency toward blocking.

A coating structure for a sheet-like substrate is disclosed including cellulosic fibres and a sheet-like product. The structure includes at least one pre-coat layer and a top coat layer, where the pre-coat layer(s) and the top coat layer include 10-90 weight-% of a styrene (meth)acrylate copolymer which is polymerised in the presence of a stabiliser, and which has a glass transition temperature Tg20 C., preferably 15 C., more preferably 13 C. Furthermore, the pre-coat layer(s) includes a polysaccharide, such as starch, and the top coat layer includes 5-60 weight-% of at least one water-soluble coating binder, which is selected from polysaccharides and polyvinyl alcohols, as well as at most 5.0 weight-% of a cross-linker, which reacts with OH or COOH groups.

The present invention relates to a coating composition for coating of paper or paperboard, said composition comprising: a pigment, a binder, an optical brightening agent (OBA), a colorant, and a sugar alcohol, and to paper or paperboard coated with at least one layer of the coating composition. The present invention further relates to a method for preparing said coating composition and to an OBA premix useful in the method of preparing the coating composition, said premix comprising an OBA, a sugar alcohol, and optionally a colorant, wherein the OBA and sugar alcohol together make up at least 10% by weight, preferably at least 20% by weight, based on the total weight of solids in the premix.

The invention relates to a method for producing a color-changeable decorative surface. In order to provide a decorative surface that can be changed in a particularly simple manner in terms of its coloring by the end consumer and which is particularly cost-effective and resistant, it is provided that at least one layer of a coating agent, which enables the absorption of color particles, is applied.

The invention relates to a method for producing a synthetic resin surface or lacquered surface with a variable color, having the steps of providing a support layer with a lower face and an upper face, impregnating the support layer with a liquid impregnant without using a pickling additive and at least drying the impregnated support layer. The aim of the invention is to provide a decorative surface, the coloring of which by the end consumer can be modified in a particularly simple manner and which is particularly inexpensive and resistant. This is achieved in that a layer of coating agent is deposited on the upper face of the support layer and is dried, and the support layer is then connected to a material, wherein the layer is cured in order to form an open-pore layer which is at least as transparent as possible upon drying and/or connecting to the upper face.

The present disclosure is drawn to a recording medium including a substrate, a first coating applied to the substrate, and a second coating applied to the first coating. The first coating can include inorganic pigment, fixative agent, and a first binder. The second coating can include inorganic nanoparticles, aluminum silicate, and a second binder.

Paper and paperboard coatings are disclosed using a modified clay which is characterized by an average shape factor less than 60, a sediment void volume greater than 48%, and containing less than 30% by mass of particles less than 1 micron in diameter.

A method for manufacturing a paperboard structure includes passing a paperboard substrate through a hot-hard calender to yield a calendered paperboard substrate, the hot-hard calender including a nip defined by a thermo-roller and a counter roller, wherein a contact surface of the thermo-roller is heated to an elevated temperature. The method then includes applying a basecoat to the calendered paperboard substrate to yield a basecoated paperboard substrate, the basecoat includes a basecoat binder and a basecoat pigment blend. The method further includes applying a topcoat to the basecoated paperboard substrate.

Disclosed herein is a wallpaper, including: (a) a paper substrate including a paper layer and an ink decorative layer attached to an upper surface of the paper layer that faces away from the wall during use; (b) a fluorine-containing coating attached to a surface of the ink decorative layer; and (c) a supporting layer attached to a lower surface of the paper substrate, in which the supporting layer comprises 25 to 45 wt % of polyacrylate, 25 to 40 wt % of a styrene-acrylic acid copolymer and 10 to 50 wt % of inorganic particles based on the total weight of the supporting layer, wherein the inorganic particles are selected from the group consisting of silicon dioxide, titanium dioxide, calcium carbonate, kaolin clay, diatomite and talc powder, and a combination of two or more thereof.
