Zusammenfassung:	PCT No. PCT/EP91/00358 Sec. 371 Date Dec. 27, 1993 Sec. 102(e) Date Dec. 27, 1993 PCT Filed Feb. 27, 1991 PCT Pub. No. WO91/13923 PCT Pub. Date Sep. 19, 1991The invention relates to a process for the production of multi-layer finishes in which the base coating contains crosslinked polymer microparticles which are obtainable by (A) reacting a polyester-polyol or a mixture of polyester-polyols with a polyisocyanate or with a mixture of polyisocyanates and (B) when at least 25% of the NCO groups have reacted, dispersing the resulting reaction mixture in water.
