The invention relates to a method of increasing the stonechip resistance of OEM coat systems composed of an anticorrosion coat, a surfacer coat, and a concluding topcoat, in which 0.1% to 30% by weight, based on the nonvolatile fractions of the coating material, of electrically charged inorganic particles AT whose ratio D/d, the ratio of the average particle diameter (D) to the average particle thickness (d), is &#x3e;50 and whose charge is at least partly compensated by singly charged organic counterions OG, are incorporated into the coating material that is used to produce at least one of said coats and that comprises at least one polymer P, and the coating material is applied and, lastly, is cured.

Method for the production of high-impact layers

Disclosed is an aqueous effect basecoat material comprising at least one liquid-crystalline aqueous preparation (WZ) in fractions of 1% to 99% by weight, based on the aqueous basecoat material, at least one film-forming polymer (FP), and at least one effect pigment (EP).

Waterborne effect base coats having improved optical properties

Aqueous dispersions entirely or substantially free from volatile organic compounds, comprising

Aqueous dispersions that are free or substantially free from volatile organic compounds, and method for their production and use thereof
