Zusammenfassung:	Coating composition, in the form of a solution, comprises at least one polyurethane urea, where the polyurethane urea is terminated with a copolymer unit of polyethylene oxide and polypropylene oxide. An independent claim is included for producing the polyurethane urea-solution comprising: reacting the polycarbonate polyols and optionally the polyols in the melt or in the presence of solvent in a solution, until all hydroxyl groups are used; adding further solvent and optionally adding dissolved diamines or amino alcohols; and optionally blocking the residue of isocyanate groups with a monofunctional aliphatic amine after reaching the desired viscosity.
