Abstract:
PCT No. PCT/EP96/05693 Sec. 371 Date Aug. 21, 1998 Sec. 102(e) Date Aug. 21, 1998 PCT Filed Dec. 18, 1996 PCT Pub. No. WO97/23307 PCT Pub. Date Jul. 3, 1997A description is given of a process for preparing a multilayer coating on a substrate surface, in which (A) an aqueous coating composition (ii) containing as film-forming agent an aqueous polymer dispersion is applied as basecoat (II) to a substrate surface coated with an aqueous basecoat (i), (B) the composition applied in step (A) is subjected to partial drying, (C) an appropriate transparent topcoat composition is applied to the basecoat (II) thus obtained, and (D) the basecoats (I) and (II) are baked together with the topcoat, wherein the basecoat composition (II) contains an aqueous polymer dispersion comprising (x) an acrylate polymer based on from 30 to 60% by weight of C1-C8-alkyl (meth)acrylate monomers, from 30 to 60% by weight of vinyl-aromatic monomers and from 0.5 to 10% by weight of (meth)acrylic acid, and (y) a thickener, which does not have an associative effect, containing an acrylate copolymer based on (C1-C6)-alkyl (meth)acrylate and (meth)acrylic acid.
