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 composition for a corrugated paper board is described. The corrugated paper board includes an inner liner sheet and an outer liner sheet adhered to opposite sides of a corrugated medium. The coating composition includes a pre-coat layer and a topcoat layer. The pre-coat layer includes an ink fixer agent and a pigment, and is disposed on one or both of the liner sheets. The topcoat layer is disposed on top of the pre-coat layer to form an ink receiving layer. The topcoat layer includes a wax and is devoid of the ink fixer agent.

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.

A coated paperboard including a paperboard substrate having a first side and a second side, and a multilayer coating having two or more layers in contact with the first side of the paperboard substrate, the multilayer coating including a base coating in contact with the paperboard substrate, the base coating having a coat weight from 6 to 10 pounds per 3000 ft.sup.2, and a top coating forming the outermost layer of the multilayer coating, the top coating having a coat weight from 3 to 10 pounds per 3000 ft.sup.2, wherein the multilayer coating comprises binder and pigment, the binder comprising one or more synthetic polymer binders and one or more natural biodegradable binders, and wherein the coated paperboard has a caliper of at least 0.010.

In a decorative material, a matting agent is added to, of a first gloss-adjusting layer and a second gloss-adjusting layer, one with lower gloss, where the matting agent has a particle diameter of 1.0 times or more the thickness of the gloss-adjusting layer with lower gloss. Accordingly, sufficient unevenness can be imparted to the surface of the gloss-adjusting layer; thus, glossiness does not increase in oblique observation, and low gloss can be maintained. Therefore, it is possible to provide a decorative material having a feeling of unevenness obtained by the difference in gloss that hardly changes even when observed obliquely.

The invention relates to a coated packaging material that has a substrate having a base material of cellulose, an outer side to be faced away from the packaging item as well as an inner side to be faced towards the packaging item. The inner side of the substrate carries at least one layer of an aqueous composition, which includes at least polyvinyl alcohol and/or at least one polyvinyl alcohol copolymer as well as a cross-linking agent, wherein the aqueous composition has at most 40% by wt. of polyvinyl alcohol and/or polyvinyl alcohol copolymer and a total solid content of at most 55% by wt. The layer and cross-linking the polyvinyl alcohol and/or the polyvinyl alcohol copolymer is dried with the aid of the cross-linking agent with formation of a barrier layer for hydrophobic compounds are performed.
