ABSTRACT:
A multicoat system comprising(I) at least one constituent (IA) comprising mesomorphic polyelectrolyte complexes prepared by reacting, in a liquid phase (IB), at least one polymeric and/or oligomeric, organic, anionic polyelectrolytes (IC) with at least one polymeric and/or oligomeric, organic, cationic polyelectrolytes (ID) and/or at least one cationic surfactant (IE) or at least one polymeric and/or oligomeric, organic, cationic polyelectrolytes (ID) with at least one anionic surfactant (IF) in a stoichiometric or non-stoichiometric ratio, pouring the resulting liquid phase (IG) onto a substrate or into a mold and allowing it to solidify, and heat-treating the resulting solid (IH); and(II) at least one coat (IIA), which is three-dimensionally crosslinked, prepared by applying at least one aqueous, thermally curable coating material (IIB) comprising at least one binder (IIC) and at least one crosslinking agent (IID), to the surface of the constituent (IA), and thermally curing the resulting wet film (IIE).
