Beschreibung
Zusammenfassung:	The present invention relates to a method for producing a multi-coat colour and/or effect paint system. The method of the invention is characterized in that a pigmented aqueous base coat material is employed that comprises at least one phosphine oxide characterized by the following structural formula (I): where the radicals R1 to R3 are selected from the group of aliphatic or aromatic hydrocarbons. The sum of the weight percentage fractions of all the phosphine oxides of structural formula (I) is 0.1 to 5 wt%, based on the total weight of the base coat material. The invention further relates to the corresponding base coat materials, to a corresponding multi-coat colour and/or effect paint system, and to the use of the phosphine oxides in pigmented aqueous paints. The invention relates, moreover, to a method for repairing defects on multi-coat colour and/or effect paint systems produced by means of the method of the invention above.
