摘要： The invention concerns an aqueous two-component coating agent based on one or a plurality of polyols and one or a plurality of polyisocyanates, in particular for coating plastics substrates, the polyol(s) being present in a first component and the polyisocyanate(s) being present in a second component and the components being combined before application. When the components have been combined, the coating agent comprises the following constituents: between 10 and 40 wt % of one or a plurality of polyols with a number average of the molecular mass of between 300 and 2,000,000, an OH number of between 10 and 400 mg KOH/g and a content of up to 400 milliequivalents/100g of solid resin of ionic groups and/or groups which can be converted into ionic groups; between 0.5 and 10 wt % of one or a plurality of chlorinated and/or unchlorinated polyolefins; between 1 and 35 wt % of electrically conductive pigments and/or fillers; between 5 and 30 wt % of one or a plurality of organic solvents; between 25 and 75 wt % water; and between 1 and 30 wt % polyisocyanates with an average of at least two free isocyanate groups per molecule, the total of these constituents being 100 wt % and the quantitative proportion between the polyisocyanate component and the polyol component being such that the ratio between the number of reactive NCO groups and the number of OH groups is between 5:1 and 0.5:1.
