Summary:Aqueous dispersions of composite particles composed of addition polymer and finely divided inorganic solid and obtainable by free-radical emulsion polymerization on a mixture of ethylenically unsaturated monomers including at least one ethylenically unsaturated alkoxysilane monomer in an aqueous medium in the presence of a dispersely distributed, finely divided inorganic solid and at least one dispersant are used to prime mineral substrates. Aqueous dispersions obtainable by blending an addition polymer obtainable by free-radical emulsion polymerization of a mixture of ethylenically unsaturated monomers including at least one ethylenically unsaturated alkoxy silane monomer in an aqueous medium with a dispersely distributed, finely divided inorganic solid in the presence of at least one dispersant are used to prime glasslike substrates.
