Zusammenfassung:	PCT No. PCT/EP90/02148 Sec. 371 Date Jul. 28, 1992 Sec. 102(e) Date Jul. 28, 1992 PCT Filed Dec. 11, 1990 PCT Pub. No. WO91/09685 PCT Pub. Date Jul. 11, 1991.A process utilizing a pigmented aqueous basecoat composition which contains as the film-forming material a water-thinnable emulsion polymer. The water-thinnable emulsion polymer is prepared in a two-stage emulsion polymerization. In the first stage a polymer is prepared having a glass transition temperature (TG1) of +30 DEG to +110 DEG C. In the second stage a mixture of monomers is polymerized in the presence of the polymer prepared in the first stage, which mixture, polymerized on its own, would give a polymer with a glass transition temperature (TG2) of -60 DEG to +20 DEG C. The hydroxyl value of the emulsion polymer is between 2 and 100.
