Abstract
The present invention relates to an acidic aqueous particulate composition containing, in addition to iron(III) ions, fluoride ions and at least one water-insoluble, dispersed organic binder, a water-insoluble, dispersed oxide pigment with elevated resistance to agglomeration for the autophoretic deposition of organic-inorganic hybrid layers onto metal surfaces, the composition additionally containing at least one anionic wetting agent which comprises functional groups selected from sulfonates, phosphonates and/or carboxylates. The invention furthermore comprises the use of such a composition for the autodeposition of a film-forming organic-inorganic hybrid coating onto metal surfaces which are at least in part selected from surfaces, the main constituents of which are iron, zinc and/or aluminum.
