Patent ID: 7297375

Claim:
An aqueous coating material curable physically, thermally and with actinic radiation comprising A) at least one stabilized polyurethane, as binder B) at least one effect pigment or a mixture of a color pigment and an effect pigment, and C) at least one transparent or colorless powder present in an amount of from 0.09 to 5.0% by weight, based on the solids content of the coating material, the powder C) being substantially inert with respect to the other constituents of the coating material and whose particles have an average particle size of from 3.0 to 7.5 μm, a particle size distribution such that the maximum particle size is below 10 μm, and a density of from 0.8 to 3.6 g cm −3 , wherein the at least one stabilized polyurethane, the at least one effect pigment, and the at least one transparent or colorless powder are present in a combination such that a coating prepared from the aqueous coating material provides a cloud free metallic effect.
