Abstract
A pigmented aqueous basecoat material is disclosed. The pigmented aqueous basecoat material includes a polyether-based reaction product which is preparable by a reaction of trimesic acid with at least one polyether of the general structural formula (I) R is a Cto Calkylene radical and n is selected accordingly such that the at least one polyether possesses a number-average molecular weight of 500 to 5000 g/mol. The trimesic acid and the at least one polyether are used in the reaction in a molar ratio of 0.7/2.3 to 1.6/1.7 and the resulting reaction product possesses an acid number of 10 to 50 mg KOH/g.
