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.
