Abstract: Post-treatment method and/or fine patterning method of effect pigment-containing or metal-containing particle-containing objects, for example car body parts or cosmetic containers or layers, for example paint layers or printing ink layers, by means of energy input (e.g. heat input, preferably by laser light), whereby the hiding power of metal-containing pigment platelets or metal-containing particles is permanently reduced by their change in shape factor. In the treated surfaces, this change in shape factor causes a permanent local increase in transparency, translucency or transmission for electromagnetic waves, in particular radar wave, radio wave and/or light wave transmission, and/or a local reduction in reflectance, for example for the production of painted radomes.

Abstract: The present invention relates to a pigmented coating composition for an automobile clear coat, to the use of a coating composition of this type, to an automobile clear coat, and to a process for the coating of an automobile with a clear coat.
