Abstract: The invention relates to a process of forming an embossed coated substrate. The process comprises the steps of: (I) forming on a substrate at least one coating whose composition comprises a radiation-curable polyurethane dispersion, (II) embossing the coated substrate on a relief surface, (III) irradiating the embossed coated substrate to cure the polyurethane-containing coating. An application of the process is the manufacturing of caul paper.

Abstract: The invention relates to a water based polymer composition comprising a biopolymer and a synthetic polymer resin. The biopolymer results from a mechanical thermoplastic processing of a polysaccharide and/or protein starting material using shear forces in the presence of a crosslinking agent. The synthetic polymer resin consists of a water based hydrophilic resin and/or hydrophilic/hydrophobic resin. These compositions have a good storage stability. They are intended for the production of coatings with fair properties.
