Tissue products are disclosed containing an additive composition. The additive composition, for instance, comprises an aqueous dispersion containing an alpha-olefin polymer, an ethylene-carboxylic acid copolymer, or mixtures thereof. The alpha-olefin polymer may comprise an interpolymer of ethylene and octene, while the ethylene-carboxylic acid copolymer may comprise ethylene-acrylic acid copolymer. The additive composition may also contain a dispersing agent, such as a fatty acid.

The invention provides a high strength wood-plastic coated coextruded composite material. The material is composed of a core layer and a coating layer. The coating layer coats the surface of the core layer through a co-extrusion technology, biomass powder in the core layer is improved to a biomass fiber material, because of a large length-diameter ratio, the biomass fiber material not only plays a "filling" role in a wood-plastic composite material, but also plays a "reinforcing" role, greatly improves the mechanical properties of the composite material, especially improves the impact resistance, creep resistance and other properties, thereby broadening the application scope of the wood-plastic composite material. In addition, the coating layer involved in the invention preferably contains ethylene-methyl acrylate copolymer resin, ethylene-vinyl alcohol copolymer resin and high strength fiber, thus being conducive to further enhancing the mechanical properties of the composite material and the binding force with the core layer.

This patent describes an ink jet printable heat transfer material with cold release properties. The invention consists of multiple layers of coatings applied to a suitable substrate, typically paper. The first optional layer coating consists typically of a pigmented coating bound together with a synthetic or natural binder and is applied in sufficient quantity to level and densify the surface of a given substrate. The second coating is applied over the first and consists of a silicone coating with a controlled surface energy. The surface energy must be such that the subsequent aqueous coatings can be applied over top with good wetting and adhesion, but low enough for an easy removal from the heat transfer after cooling. A third or wash layer is applied over the silicone release layer. This layer must easily wet and adhere to the silicone release layer so the coating does not come off during subsequent coating passes and during handling by the user. The wash layer consists of one or more thermoplastic polymers including ethylene acrylic acid, waxes, and other polymers along with dispersions of non-water soluble plasticizers and antioxidants. An ink receptive layer consists of a low binder thermoplastic organic pigmented coating containing non-water soluble plasticizers and antioxidants along with water soluble and insoluble cationic polymers and/or cationic inorganic pigments. The non-water soluble cationic materials, either organic or inorganic, aid in the retention of the dyes and reduce the wet bleed and wash out of the dyes when the transfers get wet.

The emulsion has such advantages as high wet adhesivness of the coating film and high washing resistance of the coating film.
