摘要： The invention concerns a two-component coating agent with a) a water dilutable binder component of a polyester resin base and/or polyacrylate resin base, whereby the polyester and/or polyacrylate resin has a content of hydroxyl groups of 2.5 to 8% by weight OH and b) an aqueous organic polyisocyanate component of at least one polyisocyanate with free isocyanate groups which is prepared ready for use for a limited time by the stirring of the polyisocyanate component b) into the binder component a) and hardens by cross-linking of the binder component with the polyisocyanate to the binder components according to the invention are provided as aqueous emulsions of a water insoluble carboxylate-free and sulfanate-free polyester resin and/or polyacrylate resin, whereby the emulsion is produced with the aid of an emulsifier added to the polyester or polyacrylate resin. The subject of the invention is, further, a process for producing the water-dilutable binder component a).
