Process for the production of multi-layer lacquer coatings by electrophoretic deposition of a first coating layer of a first, aqueous coating composition onto an electrically conductive substrate, application of a second coating layer based on a second, powder coating composition and joint baking of the coating layers so obtained, which process is characterised in that a powder coating composition is used for the second coating layer which is based on binders which contain no diene-based polymer units, wherein the coating composition is selected such that the minimum baking temperature range of the second coating layer is above that of the first coating layer or overlaps with this range in such a manner that the lower limit of the range of the second coating layer is above the lower limit of the range of the first coating layer.
