Abstract:
1. A multicoat system comprising (I) at least one coating layer (IA) which comprises mesomorphic polyelectrolyte complexes selected from I.1.1 and I.1.2 and which are prepared by I.1) reacting, in a liquid phase (IB), I.1.1) at least one polyelectrolyte selected from the group oonsisiting of polymeric and oligomedc, organic, anionic polyelectrdytes (IC) with at least one compound selected from the group consisting of polymeric and oligomeric, organic, cationic polyalectrolytes (ID) and cationic surfactants(IE) or I.1.2) at least one polyelectrolyte selected fom the group consisting of polymeric and oligomeric, organic, catonic polyelectrolytes (ID) wifth at least one anionic surfactant (IF) in a stoichiometric or non-stoichiometric ratio, to form liquid phase (IG), I.2) pouring the resulting liquid phase (IG) onto a substrate or into a mold and I.3) allowing it to solidify, and I.4) heat-treating the resulting solid (IH); and (II) at least one three-dimension ally crosslinked coating layer (IIA) formed by (II1) applying to coaling layer (IA) at least one aqueous, thernally curable coaoing material (IIB) comprising II.1.1) at least one binder (IIC) and II.1.2) at least one crosslinking agent (IID), and II.2) thermally curing the resulting wet film (IIE).
