Abstract: A foldable paper-based substrate coated with primer coat and top coat. Primer coat includes a wax-free aqueous dispersion wherein a dry film thereof has a flexibility of at least 1100% for a film thickness from about 1.0 to about 2.5 mm. Top coat is blocking resistant and includes an aqueous dispersion of a polymer providing water resistance, grease or oil resistance, heat resistance, odor barrier, moisture barrier and/or heat sealability to the paper-based product. The top coat aqueous dispersion is characterized in that a dry film thereof has a flexibility of at least 570% for a film thickness from about 1.5 to about 2.5 mm. A process for preparing the coated foldable paper-based substrate includes applying the primer coat to the surface of the paper-based substrate, applying the top coat and drying the coats. The primer coat may be dried before application of the top coat.

Abstract: 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.

Abstract: A paper for a label which has an uncoated basic paper substrate on a verso side of which there is applied at least one coat of a liquid polymer, into which is incorporated one of an opacifier and an opacifying filler, intended to give product opacity in a dry state and in a wet state, adding to the opacity of the uncoated basic paper substrate so as to create a coat that is opaque and limits the ingress of water, between a product that is to be labeled and the uncoated basic paper substrate for use of the product in a wet environment or that is to be immersed in water, while at the same time preserving the qualities of the label.

Abstract: A method of producing a printed electronic device on a thin PDMS film which includes coupling a first layer of a water-soluble polymer to a substrate and drying the first layer of the water-soluble polymer. The method further includes coupling a second layer of a crosslinkable PDMS polymer to the first layer of the water-soluble polymer and curing the second layer of the crosslinkable PDMS polymer to form the thin PDMS film. The method also includes printing one or more functional layers on the thin PDMS film and drying the one or more functional layers on the thin PDMS film to form the printed electronic device coupled to the substrate.
